FROM THE EDITOR | Linda Jesson This month we celebrate Earth Day—an important day for us because the heart of our gardens really begins with the Earth. So, in this issue of Maximum Yield we are all about articles that promote a more sustainable way of living. Jonathan Valdeman talks about the benefits of greenhouse growing yearround, and Eric Hopper takes us through the steps of making an organic transformation.

Message from the

Editor Linda Jesson

We've also included features on composting wood (it takes at least a year), the best starter crops (there are five we recommend) and how to best germinate seeds (it's so easy!). Matt Lebannister also sheds some light on effectively combining the right lights with the right levels of carbon dioxide to maximize your indoor garden's growing power. Maximum Yield is also happy to welcome back Erik Biksa, an experienced gardener who, in this issue, writes about raising transplants for larger yields later on. You’ll also be able to find him regularly on our Facebook page. To top off our April issue, we also feature some interesting trivia and some of the up and coming products filling the shelves of retail grow stores across the country.

Big Charts:

Will More Stuff Give Better Yields?

Erik Biksa

I have been growing for over a year and I am starting to get the hang of things. It took some work to get the environment to stay optimal with the lights on, but that’s dialed in now. At the recommendation of a friend, I started simple with my nutrients and growing medium. My harvests are good, but I know they could be better. The environment is great, so I want to see if I can step up my yields and quality with my growth method. I plan on changing my large containers to an automated drain-to-waste system with coco coir as the medium. My question is: Do I really need all of that stuff I see on the “experienced” sections of hydroponic nutrient feed charts? What about organics for my system?

You speak for a lot of growers, and I would like to bring attention to the fact that you are building your garden on a solid platform by optimizing one area at a time. By not changing more than one critical factor at a time, you can see if your changes are working or not. One of the things you should consider in your decision on what program to use, or the types of products you need to customize your own program, is how you’re going to set up your drain-towaste system. The main factor is if the solution will be pre-mixed before being fed to the crop (i.e. reservoir and pump via timer) or mixed while the crop is being fed (i.e. dose system injects nutrient concentrates and pH adjusters into the main line from concentrate reservoirs)? Besides the big difference in cost, the critical factor here is that one solution is left standing and the other is mixed fresh. In the standing solution, even if recirculated or aerated between feedings, you run the risk of having biological components become active in the

reservoir rather than in the growing medium. Also, some ingredients and microbial life don’t like to swim, and nasty imbalances and growths might occur. Now, if you mix that same solution fresh and apply it to the growing medium right away, you typically won’t have any issues because the ingredients are being delivered in balanced ratios and at the correct pH. So, if you go with a standing reservoir, try and limit the biological load. In other words, stick to mostly synthetic nutrient sources and go lighter on the biologicals. If you do use bio-ingredients, reservoir temperature is critical and the solution shouldn’t stand for more than a few days. Also, it’s a good idea to recirculate or aerate it between feedings if left standing for more than a few hours. If you go with an accurate dosing system, look for one that is suitable for injecting organic liquid concentrates and you’ll typically be able to run totally organic solution without issue. Look at it this way: synthetics are like leaving a glass of orange juice made from drink

crystals out on the counter—not much is going to happen quickly. Then try that with fresh squeezed; this OJ is likely to turn bad within a day or two (especially when coupled with warmer temperatures). To answer the other part of your question: no, your plants don’t need all that stuff to survive until harvest. However, that stuff can be used as the building blocks to create better flavors and aromas while potentially making your plants hardier and capable of yielding greater harvests. If you want to get more out of something, you typically have to put more into it. Choose wisely, though. Do your research on a feeding program. What works great in one garden might not do as well in another. It depends largely on the application; although, today’s crop nutrient technologies can help make anybody a better gardener than ever possible before. Cheers, Erik Biksa grozine.com

hydroponic news, tips and trivia

Heroic Hazelnuts Just a few years ago the entire hazelnut industry in Oregon was threatened by eastern filbert blight, but decades of research by Shawn Mehlenbacher (professor of horticulture at Oregon State University) has ensured a supply of resistant varieties. In the late 1970s, scientists discovered a blight-resistant pollinator in fields, with a gene they named gasaway, and began the slow process of breeding trees that shared that resistance. By the time farmers were really hurting, researchers could offer plants that were not perfect, but had at least some resistance. Now, those trees are all over the Willamette Valley and growers are putting their hope in them, replacing blighted trees with these new varieties. (Source: npr.org)

hydroponic news, tips and trivia Understanding Microbes Blowing in the Wind USDA scientists are studying travel patterns of microbes in soils carried off by strong winds. The work has implications for soil health and could lead to management practices that minimize the damage to soils caused by wind erosion. Researchers collected airborne dust and samples of a type of organic soil susceptible to wind erosion from fields where potatoes, beets and onions had grown a few years earlier and exposed them to windy conditions using a portable wind tunnel. They characterized the bacteria they found in both the source soils and the wind-eroded sediments. The study’s results showed that certain types of bacteria, known as bacteroidetes, were more predominant in the fine dust. Other types, known as proteobacteria, were more predominant in coarse sediments. (Source: ars.usda.gov)

Sugar Makes Vegetables More Palatable for Children Valerie Duffy, a dietician and researcher at the University of Connecticut, came up with the idea of sweetening vegetables to make them more palatable to young people. In this study, funded by the American Diabetes Association, researchers offered kids two servings of the same vegetable. In a double-blinded experiment, they lightly misted one serving with plain water and the other with a dilute solution of aspartame. Two out of three kids preferred the vegetables that had been sweetened. Duffy said the sweetener should not be of concern to parents as only small quantities are involved. She also suggested that once better eating habits are established the sweetener can be removed. (Source: freshplaza.com)

University of Maine Battling Potato Blight University of Maine’s Department of Plant and Soil Sciences graduate student Kristen Michelle Brown is working with two potato varieties from the university’s breeding program that will hopefully one day hold a late blight-resistant gene. “Late blight is a big problem in Aroostook County because the climate is so fantastic,” she said. “The only way you can treat it is by pouring fungicides onto your plants. There are genes in a number of potato varieties that are late blight-resistant genes. The idea is that if you can get those genes into your potato varieties then you don’t have to use as much fungicide,” said Brown, whose research is a reproduction of a 1977 experiment by researcher William Fry.

Mix-and-Match Cover Cropping Can Optimize Organic Production Farmers can fine-tune their use of cover crops to help manage costs and maximize benefits in commercial organic production systems, according to USDA scientists. Agricultural Research Service horticulturalist Eric Brennan examined several different cover cropping strategies for an annual organic lettuce-broccoli production system. He selected three winter cover crops often grown in the Salinas, California, area—rye, mustard and a legume-rye mix—and planted each cover crop using either a typical seeding rate or a seeding rate that was three times higher. The legume-rye and rye cover crops produced approximately 25% more dry matter biomass than the mustard crops. But effectively suppressing weeds with the legumerye crops required seeding at three times the typical rate, while rye and mustard crops appeared to suppress weeds adequately with typical seeding rates.

California Farms Smaller Than National Average The average size of a California farm remains significantly smaller than the national average, according to a report released in February. The US Agriculture Department says the average California farm totaled 316 acres, compared to the national average of 421 acres. The report listed the number of farms in California at 80,500, down slightly from the previous year. (Source: cfbf.com)

Test for Mercury-contaminated Water with a Mobile Phone Researchers have developed test sheets that change color when exposed to mercury in water, which will enable quick, cheap and on-site mercury detection. The results of the test can be determined by eye, but for more accuracy, the sheet can be photographed with a mobile phone and compared with color reference values using an image editor program on the phone. The test sheets contain rhodamine, a florescent organic compound that acts as the mercury sensor. The research team calibrated these sheets to change color when the mercury contamination in the water exceeds two parts per billion of divalent mercury-Hg(II). (Source: treehugger.com)

San Diego Avocado Industry in Decline Avocados in San Diego County are in decline and trees are being replaced with other crops. Grower Phil Pace bought 15 acres of property more than a year ago. Since then he says two water hikes— a 30% jump, followed by a 10% hike—have made the avocado crop too costly. According to the San Diego County Farm Bureau, in a fiveyear span, the avocado acreage in California went from 26,000 acres in 2007 to 17,673 acres. (Source: freshplaza.com)

Microbes Team Up to Boost Plants’ Stress Tolerance While most farmers consider viruses and fungi potential threats to their crops, these microbes can help wild plants adapt to extreme conditions, according to Penn State virologist, Marilyn Roossinck. A team of researchers tested four different viruses and several different plants, including crops such as rice, tomato, squash and beets, and showed that the viruses increased the plants’ ability to tolerate drought. Virus infection also provided cold tolerance in some cases. Discovering how microbes collaborate to improve the hardiness of plants is a key to sustainable agriculture that can help meet increasing food demands, in addition to avoiding possible conflicts over scare resources, said Roossinck.

Find Free Seeds By ‘Renting’ From a Library Seed libraries have sprouted up all over the place, though an interested person probably has an easier time finding a branch of their public book library than any local seed library. That’s why the Basalt Regional Library in Colorado has made it easier for patrons to find more than just books at their branch. Here’s how it works: a library card gets you a packet of seeds. You then grow the fruits and vegetables, harvest the new seeds from the biggest and best, and return those seeds so the library can lend them out to others. (Source: treehugger.com)

MIT Scientists Engineer Yeast Cells to Produce More Efficient Biofuels In the hunt to replace petroleum, scientists are looking for more efficient ways to produce biofuels from organisms. A team of researchers at MIT have engineered yeast to manufacture the heavy alcohol, isobutanol. Yeast normally creates isobutanol in small amounts, and by altering the cell so that the production takes place entirely in the mitochondria, the scientists were able to boost the amount of the chemical by 260%. While still not able to generate enough isobutanol on an industrial scale, the technology holds the potential to open up biosynthetic pathways for a whole host of other chemicals. Currently, the researchers are still working towards increasing the production of isobutanol while reducing the amount of ethanol, a major by-product of sugar breakdown. (Source: inhabitat.com)

Local Food Movement a Game Changer for Established Producers A report released by Rabobank’s Food & Agribusiness Research and Advisory group titled “Local Foods: Shifting the Balance of Opportunity for Regional U.S. Produce” finds that the growing local food movement, in which consumers seek out and purchase foods grown in closer proximity to them, is causing smaller regional producers to take market share from established producers who don’t qualify as locally sourced. This local food movement has evolved into a permanent mainstream trend, which is generating more opportunities for regional American growers, who traditionally had less market share than larger, more well-established national suppliers.

In addition, the Liquid Ladybug Mite Shield was invented to prevent reinfestation during and after treatment. Wrapping a simple 0.5-in.-wide sponge strip soaked with Liquid Ladybug around the stem during treatment prevents mites and hatching eggs that fall out of plants into the growing medium from crawling up back into the plants. Liquid Ladybug is a zero-environmental-impact pesticide safe for people, pets and plants. Ask about it at your local garden retailer today.

Bluelab pH Probe KCl Storage Solution We know it is extremely important to care for and store pH probes correctly. pH probes are sensitive glass instruments that age through normal use. The life and performance of pH probes is reduced heavily when they are stored dry. Remember, keep your pH probe wet—if it dries, it dies! Bluelab pH Probe KCl Storage Solution is made specifically for use with Bluelab pH products. Manufactured to high laboratory standards, it is designed to increase response time and maximize the life of Bluelab pH pens and probes. For best results, use the solution to store the pH probe after use, and hydrate monthly. Contact your local Bluelab retailer for more information.

The Roottrapper II The versatile and effective Roottrapper II is the only container that can grow with virtually any media and growing style. Unlike air pruning bags, the Roottrapper II uses a very different technique called roottrapping, which happens when the root tip grows into the fabric and gets stuck or trapped. Unable to continue to grow forward, the root is forced to branch. This process is repeated over and over again as more roots meet the container wall, thus creating a fibrous, non-circling root system. Because these containers do not require the root tip to dry out, the Roottrapper II can be used effectively with continuous drip systems. Outdoors, the containers offer the additional benefit of keeping the root zone much cooler. For more information, contact a garden supply store.

My Hydro Minerals by Eco Organics

X Nutrients

Eco Organics introduces My Hydro Minerals™, the worlds’ only magnetic vortex-activated mineral supplement for massive root growth, early maturity and higher yield for hydroponic growing. My Hydro Minerals is not a fertilizer; it makes all fertilizers work better. It is 62 ionic minerals extracted from ocean water that grow roots so fast and dense in six weeks that you can’t stick a finger through them. Tests have produced roots so massive and fast that treated plants are maturing two to four weeks earlier than untreated plants, thus shortening the time to harvest. This indicates that the number of crops per year can be increased for an additional crop-per-year yield even though the amount of fertilizer and energy in that time is unchanged.

Tasty Tomatoes

Most people have tasted, or rather not tasted, hydroponically-grown tomatoes during the off-season. Dampened by the cold of winter, consumers are looking for that taste of warmer times only to be rewarded with a shell of the summer tomato. Color, taste, firmness and selection are usually severally lacking. There is still much experimentation that is needed until we produce a great tomato in the winter, but research is truly a work in progress. While breeding programs have brought us closer to a better-flavored tomato, the scope of this article will focus on the cultural practices that should enhance the palate response. With that said, genetics should focus not only on storage qualities (shelf life, skin thickness, disease resistance for plants, etc.) but on promoting those factors associated with superior taste, which include but are not limited to soluble solids (measured by a refractometer in Brix %), pH and organic acids. Now let’s dive into the chemicals and the factors influencing tomato flavor.

Generally a good-flavored tomato possesses both a high amount of sugars and a high amount of acids.”

Maximum Yield USA | April 2013

With plant genetics aside, let’s focus on certain compounds that impact flavor. Tomatoes are roughly 90% water with the solids representing 5% to 7% of the dry weight. Tomato fruit flavor is generally created from the ratio of carbohydrates (glucose, fructose, sucrose) to organic acids (citric and malic acid). Generally a good-flavored tomato possesses both a high amount of sugars and a high amount of acids. Likewise, bland tomatoes contain a high amount of sugars to a low amount of acids. As the tomato matures, the amount of sucrose (imparts a sweet flavor) decreases as starch (not so sweet) increases. Starch consists of many linked units of glucose acting as an energy storage reserve. From this reserve, the readily metabolizable glucose units can be cleaved off for the plant’s use. When a traditional red tomato is changing from the orange to red color, the acidity drops, which increases the fruit’s pH. This has important ramifications to harvesting as tomatoes that are fully vine ripened might have a reduced blend of acid to sugar. However, the ripening process is ethylene dependent. This plant hormone gives rise to lycopene (antioxidant/carotenoid) production, the causative agent in red color change. Therefore, the implication of early harvest might slightly reduce the rising pH, but will impact the flavor attributed to lycopene that is maximized during the deep red stage of ripening. In the book Tomato Plant Culture, it is stated that the recent genetic breeding programs of tomatoes have favored increased yields, shelf life and skin thickness with the negative side effect of an increase in fruit pH. Further stating, this is why so many consumers are shifting back to the heirloom varieties as the pH is generally lower than the recent hybrid cousins and therefore generally regarded as better tasting. So now you might be asking, “How can I produce tomatoes that are high in both sugar and acid?” While some of these

Tasty Tomatoes

subsequent points below are not directly tied to flavor, they do promote healthier, more productive plants, which when coupled with the right cultivar should produce better tasting tomatoes.

Maintain ideal temperature range of 77oF daytime to 65oF nighttime Ideal and constant temperatures will influence the biochemical reactions related to the water, carbohydrate and organic acid content of the ripened fruit. Proper growing temperatures will also improve yields by increasing pollination capability and decreasing fruit drop.

Maximum Yield USAâ&#x20AC;&#x201A;|â&#x20AC;&#x201A;April 2013

Expose plant to high/full light Saturation of light by leaf receptors will maximize photosynthesis and subsequent carbohydrates that will be used for a myriad of biochemical reactions including fruit production.

Utilize a nutrient formula geared toward optimal tomato production The nitrogen ratio should be derived from nitrates more than ammonia. In addition, keeping the ratio of potassium to nitrogen high will promote thicker skin that should reduce skin cracking.

Fertilize with a slightly higher EC at 3.5 dS/m Ensuring a higher level of fertilizer is probably beneficial in a two-fold manner. In one regard, maintaining adequate levels of nutrients, like calcium, will not only improve plant vigor, but in the case of high cytosolic calcium, reduce the prevalence of blossom end rot. Secondly, the increased fertilizer (salt content) could contribute to the benefits of slight saline stress as detailed below.

Tasty Tomatoes

Experimentation by growers with new and emerging cultivars coupled with ideal cultural practices will continue to improve the tomato flavor closer to its summer relative.”

Avoid periods of drought stress followed by excess watering during cultivation Drought stress has been linked to fruit cracking and blossom end rot. Proper irrigation will go a long way in reducing both.

Store ripening tomatoes in warm temperatures

Add of sodium chloride at 35 ppm

Temperatures below 400F will cease enzymatic activity necessary for maturity.

Research studies have shown a correlation between slight salt stress and higher accumulation of soluble solids in particular sugars, organic acids and amino acids. At first one might be inclined to think this is merely a function of salt removing water from the fruit and thereby concentrating the sugar, organic acids, etc. However, one study showed that during initial fruit development, salt stress caused a doubling of starch in the fruit that subsequently increased the soluble sugars in the ripened fruit. It appears that slight saline stress at the time of initial fruit development could be advantageous, but constant saline stress likely would lead to decreased vigor of the plant and decreased yield and size of the fruit.

In conclusion, both genetics and cultural practices play a pivotal role in the overall taste of the tomato fruit. In general the smaller cherry and grape tomatoes have a higher total soluble solids (Brix %) relative to the larger ones like beefsteak. Experimentation by growers with new and emerging cultivars coupled with ideal cultural practices will continue to improve the tomato flavor closer to its summer relative. For more information on growing tomatoes in the greenhouse or field, refer to the book Tomato Plant Culture in the literature cited.

The Top Five Easiest Crops for Beginning Gardeners

by Kristen McKenzie

Finding space isn’t the biggest issue when it comes to starting your own food garden. The biggest issue is knowing what the best starter crops are.

Maximum Yield USA | April 2013

No matter

Growing one’s own produce is a nutritious, affordable alternative to the chemical-laden harvests and costly organic fare offered at the local supermarket. No matter if you have got a large backyard or a tiny apartment balcony, it’s possible to reap your own tasty fruits and veggies with minimal fuss or effort. The trick, of course, is in knowing which crops to start with. Whether you are a newbie gardener still finding your green thumb or you are a seasoned pro seeking to grow the most low-maintenance produce possible, here are the top five hardy crops guaranteed to thrive with the least amount of exertion possible. Bonus: all of these plants can be grown in pots and they’re even able to survive a little neglect here and there.

if you have got a large backyard or a tiny apartment balcony, it’s possible to reap your own tasty fruits and veggies with minimal fuss or effort.”

Potatoes This sturdy crop can be grown in straw or soil, and is easy to store once harvested (just be sure to keep in a cool, dark place). Potatoes grow quickly and can be planted successively for the greatest yield possible. You can grow these tasty nuggets by either purchasing seed potatoes at your local nursery or by simply planting old potatoes that have sprouted in the cupboard. Cover your starting tuber under 9.75 in. of soil and be sure to regularly mound dirt and mulch around the plant as it grows. If you water regularly (potatoes require 1 to 2 in. of water per week) and provide adequate light, your spuds will be ready to harvest two to three months later. Tip: Potatoes are vulnerable to frost, so be sure to plant following the last frosts of the winter season.

Strawberries Gardeners can easily achieve bountiful amounts of this sweet berry by exerting a little love and care. To begin your fruitful relationship with the strawberry, buy some certified disease-free starter plants from your local nursery or gardening center. If you don’t have a lot of space to work with, even a few plants can produce decent yields. Plant them in your desired garden bed or pot (autumn and winter months are best), sprinkle with a handful of fertilizer (tomato food is a good option), give plenty of access to sunshine, water regularly and you’ll be enjoying strawberry parfaits in no time.

Tip: Although the strawberry is considered a perennial by some, it provides its best results in the first year and should be replaced with new stock after three years.

Tomatoes

This wildly popular crop can grow nearly anywhere and in any kind of soil. Tomatoes can be nurtured from seeds, but the easier option is to get started with seedlings (select short, sturdy plants over tall, lanky ones, as these will last longer and produce better yields). As with the other crops on this list, tomatoes require two basic ingredients—water and sunshine—to thrive. Sprinkle here and there with sulfate of potash for an especially fertile crop, and place several stakes around the plant so that side shoots can sturdily continue growing upwards. Tip: Throughout the winter months, cover your tomato plant with plastic to create a mini greenhouse effect and to protect from cold winds.

Chili peppers Not only are these fiery crops easy to grow, but they also add a nice dash of color to a garden and are a great way to spice up any dish. Chili peppers can falter in colder climates, so seedlings should be planted in their permanent location at least two weeks after the last frost. This crop does need a bit more time to mature, so be patient; peppers should become ready for picking six to eight weeks after the plant blooms. Tip: Chili peppers can become hotter when left on the vine to ripen fully, so decide what level of heat you desire when choosing your harvest time.

Lettuce This leafy crop can essentially be grown year-round; however, it does prefer cooler weather, so ensure it gets plentiful water and shade during the hot summer months. It’s also extremely inexpensive to produce and a variety of seed packages can be purchased at low cost from any garden center. Tip: Cos lettuce (also known as romaine) is one of the fastest and easiest varieties to grow. It also works great for a Caesar salad.

However, just like professional athletes, experienced croppers also know that the best finishes come from a strong start.

to start your garden. These can be convenient and easy, especially if you aren’t growing for a living. Be warned, though; while you can take home some great starts, you can also take home problems (for example, insects and diseases). If you can’t talk to who grew your transplants, there can also be uncertainty as to whether or not they were sprayed with chemicals that could harm you or lessen the yield potential from your crop. This makes an even stronger case for growing your own, especially if you make your living from your crops and if you have a short season (meaning you can only bank on getting one crop planted and harvested). In other words, there’s a lot riding on the quality of your starts.

Prepare for success Fact is, the majority of the work that needs to be done when starting new plants typically has more to do with setting up to plant rather than the act of planting itself. Farmers know the importance of creating a proper seed bed: firm, but not hard, and of finer texture that still drains freely. If you are using a medium to start cuttings or seeds, that description still fits. Commercial peat or coco-based soilless mixes work great (especially if starting from seeds) and can be used to fill cell trays that fit into a standard 10- by 20-in. propagation dome/tray set-up. There are specially made plugs available too, with rockwool being just one of the choices. Different mediums will have different pretreatment requirements in order to stabilize the pH or provide/remove nutrients. Some mixes and plugs are ready to use right out of the package. Also, make sure your medium is sterile or else rots and other problems could occur easily in the warm, moist environment created. Inoculating your seeds and cuttings and encouraging them to be extra healthy is easy with additions of B vitamins and beneficial soil fungus (for example, mycorrhizae and trichoderma). Bacillus strains of bacteria also promote bigger and healthier root systems that resist the bad guys, which can occur in the soil. To get the best bang for your buck, you can soak your seeds for a short period in good-quality water mixed with ¼- to 1/8- strength beneficial inoculants and B vitamins. Once your seeds are planted and have emerged, you water with this solution until they need a regular fertilizer program, which could also include

super starts some of the beneficials you’re already using. It’s also a good idea to start with new trays and domes every time you propagate (be sure to recycle them after you’re done). For the cost, relative to how many healthy transplants you can start in a single tray, it is worth the peace of mind. However, if you prefer, mild bleach solutions and lots of rinsing can be used to sterilize and reuse plastic materials. Ninety-nine percent pure isopropyl alcohol is also effective; just use in a well-ventilated area away from sparks or flames. Nonetheless, note that plastics can get porous; so, overtime, you could be leaving behind harmful pathogens that can quickly infect the next batch of new plants.

Newbies tend to over soak it (A.K.A. killing with love), while veterans might get lazy and give a light mist once in a while to even out moisture to the different cells in the tray. However, having the right balance of oxygen-to-water around stems to root or germinating seeds is critical to having a fast and healthy trouble-free start. With peat and coir mixes, you can learn to watch the color of the medium. As it goes from dark to light, it is losing moisture. Of course, lifting the dome and touching with a

While we’re on the topic of water, using RO filtered water that has been remineralized with nutrients, vitamins, humates, etc. helps ensure that the water is free of harmful contaminants (including disease-causing organisms) while removing chlorine, which would hurt the beneficial life you introduced into your propagating medium.

Knowing when to push and when to breathe Some seeds need light to germinate, although most will pop up in dark conditions when provided with the right temperature range and moisture. However, once a tiny seedling emerges, it will need light. It’s important to get this right—with cuttings, lighting is a critical factor. The right photoperiod (duration of light to dark) and the right intensity can make all of the difference between developing a strong healthy root system in a short time frame or having the cuttings lag during rooting, making them very weak and pale by the time they are ready to plant. When plants absorb light wavelengths, they combine this light energy with the chemical energy from air and water (CO2 for leaves, O2 for roots) and nutrients to form glucose (C6H12O6). Then, when it’s dark, they grow by burning the sugars they made during the light cycle. However, temperature is king. In fact, deciding the intensity of artificial light you give your seedlings and transplants will often have more to do with temperature, as they are sealed up tight underneath a humidity dome. This is because seedlings or cuttings can get dehydrated in environments that are too warm since they can’t keep up with the water demand on a non-existent or newly developing root system. As a rule of thumb, light-loving plants like fluorescent lighting kept at a distance of 6 to 12 in. and HID lighting at least a couple feet away from their tops. For cuttings, this author finds between 800 and 1,200 lumens of T5 lighting provides the best results. Two 4-ft. long tubes roots two 1,020 trays nicely. Seedlings can start with similar lighting conditions. Maintaining steady temperature of about 80°F in the humidity dome typically gives the best balance between fast development and less risk of problems. Usually maintaining a light cycle of 18 hours on proves optimal for most varieties, however, if it gets colder with the lights out, the lights can be left on 24/7. If it gets too warm under the covered dome, you’ll need to move the light source further away. Keep in mind though that venting warm air away with powerful vent fans is not advisable, even with a snug fitting dome.

When the time is right Once about 75% of the seedlings have emerged or cuttings are showing roots, it’s time for the young crop to gradually get acquainted with the outside world. If left under the dome for longer, they will stretch and grow soft and weak, thus wasting your earlier efforts to promote optimal health. Start by taking the dome off for an hour 72

Super Starts or two and then recover by letting it sit covered for a few more hours. Then uncover for longer. If no signs of wilting appear, your plants are ready to stand uncovered. At this point, if going outdoors right away, you might want to harden your plants off by putting them outside in cooler conditions and then bringing them back in, repeating the process until they get acclimated to outdoor weather. Watch out for strong breezes or intense light, as tender young transplants can get fried quickly. Insects and animals would love to eat your seedlings, so take care here too. Keep in mind that bigger plants stand a better chance outdoors. If you are going to keep growing indoors, which is advisable, you will want to do what savvy indoor growers do. That’s to pre-veg your plants before introducing them to more intensive growing conditions. This way the young plants experience no

hiccups early on and end up producing maximized yields.

Pre-growth tactics

Instead of putting plants straight outside or even indoors into more intensive full-on vegetative growing conditions, it pays to provide them with a healthy adolescence before they become young adults. This way they will be revving to go for the big race ahead, and will have bulked up enough on the top and bottom to resist troubles and grow big. One of the best and easiest methods to accomplish this is by planting into small pots (or beer cups with drain holes—beer cups are great because they are deeper than wide so you can still fit lots of plants under one light fixture). At this point, keep fluorescent lights just off the tops of the plants (if using

Go light on nutes and heavier on things like vitamins, bacteria, fungi, humates, fulvates and amino acids. This will encourage strong healthy root development without making your plants stretch. Also, let them dry out a little between waterings (but don’t let them wilt) now that the plants have some roots to stand on. You will have hardier, studier plants that are better able to withstand stresses. However, while your plants are growing up and able to resist a bit more, do keep a watchful eye so that you don’t accidentally stress or dry out your valuable starts. After ten to fourteen days in this pre-veg stage, your plants should be very well-established and ready to transplant into larger containers or well-prepared planting holes. However, if the leaves don’t look vibrant or healthy, or you see signs of troubles from insect or diseases on them, hold off on planting. Plants are much easier to treat and handle while they are smaller, so it’s much easier to nip the problem in the bud (so to speak) at this stage. In other words, don’t ignore a problem if you do see one! They rarely go away on their own. 76

Feeling Low: Problems

by Guy Sela

with Acidic Soil

Many growers have a problem of low pH in their soil or growing media. Some soils are acidic by nature and, in other cases, low pH is the result of prolonged and intensive fertilization and irrigation. In growing media, pH changes are much more rapid than in soils. Although various growing media are available with different baseline/starting pH levels, the effect of fertilization and irrigation on their pH levels can be enormous. Soil pH below 5.5 might result in reduced yields and damages to the crop. Under these pH conditions the availability of micronutrients such as Mn, Al and Fe increases, and toxicity problems of micronutrients might occur. On the other hand, at low pH, availability of other essential nutrients, such as K, Ca and Mg is decreased and might result in deficiencies.

Common causes of low soil pH Prior to applying materials that increase pH, make sure that the low pH is not caused by an inappropriate fertilization regime. Often, an adjustment of such a regime could solve the acidity problem. This is especially true for growing media (soilless media). The ammonium/nitrate ratio is a major factor that can determine the media pH, and it can be controlled by proper fertilizer application.

Maximum Yield USAâ&#x20AC;&#x201A;|â&#x20AC;&#x201A;April 2013

In soils, intensive fertilization with ammoniumbased fertilizers or ammonium-forming fertilizers (urea) could lower soil pH. Other factors affecting soil pH include:

Parent material - type of rocks from which the soil developed.

Rainfall - soils under high rainfall conditions are more acidic than soils formed under dry conditions.

Soil organic matter - soil organisms are continuously decomposing organic matter. The net effect of their activity is that hydrogen ions are released and the soil becomes more acidic. Native vegetation - the type of the native vegetation under which the soil was formed affects the pH of the soil. Soils formed under forest vegetation tend to be more acidic.

Raising soil pH using lime The most commonly used technique to elevate the soil pH is applying agricultural lime. Solubility of lime is relatively low, so if it is applied only to the soil surface, it usually affects only the top layer of the soil, not more than an inch or so deep. In soilless media, lime should be incorporated into the media prior to planting and the process is usually logistically difficult. Waiting until after planting only makes it more complicated, because the lime should then be individually applied to each growing container or each plant. Again, due to its very low solubility, itâ&#x20AC;&#x2122;s impossible to apply it through irrigation.

Solubility of lime is relatively low, so if it is applied only to the soil surface, it usually affects only the top layer of the soil, not more than an inch or so deep.â&#x20AC;? Raising soil pH using potassium carbonate Unlike lime, potassium carbonate is highly soluble and therefore can be applied by drip irrigation. Due to its high solubility, potassium carbonate can be easily distributed throughout the root zone together with irrigation water and reach deeper soil profile. In both soils and growing media, potassium carbonate can rapidly affect chemical reactions in the root zone, thus elevating root zone pH. Irrigation with water that has a low buffering capacity (low bicarbonate content) might drastically decrease pH levels in growing media. In this case, and especially when using inert media, pH drop can present a constant problem. Applying potassium carbonate periodically, or even regularly as part of the fertilization program, can prevent the pH drop.

Potassium carbonate as a fertilizer Potassium carbonate also contributes potassium to the nutrient content of the irrigation water. Therefore, potassium carbonate can be regarded as a fertilizer and its K contribution should be considered. When applying potassium carbonate through the irrigation water, it is important to keep the pH below 7.0 in order to avoid emitter clogging. Sometimes growers need to increase the buffer capacity of the irrigation water, while keeping pH levels low enough. In this case, it is possible to add potassium carbonate to water, and at the same time to acidify the water. The acid will neutralize some of the carbonate ions, while the pH level will still be low enough to prevent emitter clogging.

Undergoing an organic transformation Many people are becoming more educated in organic production techniques and, in turn, realizing the multifaceted benefits of organic goods. In horticulture, consumer demand has sparked an increase in organically grown products. This trend can also be seen throughout the country as more and more grocery stores steadily increase their inventory of organic foods. The consumer’s reasons for supporting organic agriculture can vary greatly. Many consumers are taking a moral objection to the methods deemed acceptable by current conventional food producers. Consumers are concerned about the potential health hazards associated with the consumption of chemical pesticides and genetically modified foods that are all too common in conventional agriculture. The environmental impact has many customers turning away from conventional products and embracing organics as well. It is not just tree huggers on this bandwagon, though. The general public is gaining knowledge about the negative impacts that chemical pesticides, herbicides, fertilizers and preserving agents can have, not only on our health, but also on the health of the environment. With this heightened knowledge consumers are determining that organic products are healthier, of a higher quality and worth the slightly higher price tag.

“ Many gardeners report better taste, aroma and overall quality when using organic gardening methods.” Organics indoors

For many of the same reasons mentioned above, indoor horticulturalists are turning their gardens green. Aside from the environmental benefits, most indoor horticulturalists are attracted to organic gardening methods because of the potential increase in quality. For the average indoor horticulturalist, quality is of the utmost importance. After all, most people take the plunge into indoor horticulture because they are unsatisfied consuming tasteless products. They have decided that they can grow their own food and have absolute control over the entire process. Many gardeners report better taste, aroma and overall quality when using organic gardening methods. This rise in quality is making organic gardening attractive to the indoor gardener. Whether it’s grown indoors or out, it’s true what they say: nothing tastes better than a homegrown tomato. If organic gardening methods increase quality then the old saying could need a slight modification: nothing tastes better than a homegrown organic tomato. 82

Maximum Yield USA | April 2013

Undergoing an organic transformation Growing organically isn’t just about quality and the health of the environment. The indoor gardener has his or her own safety to worry about as well. Many indoor horticulturalists have their gardens in their homes or, at least, in close proximity to their homes. This means any pesticide or chemical fertilizer that is used can find its way into the grower’s home. Unsuspecting gardeners might touch a wall or piece of equipment in their gardens, not realizing the residual insecticide they sprayed just a few days prior is still active. They could unknowingly spread trace amounts of this toxin throughout their entire home as they go about their daily activities. Although organic pesticides aren’t to be used without caution, they tend to break down faster and be less toxic in general making them a safer choice for the indoor garden hobbyist.

“ the micro-organism symbiotic relationship regulates nutrient uptake in a way that has a direct influence over the growth rate and the quality of the fruit or flowers.” Organics and microbes

Organic fertilizers rely on the network of micro-organisms found in and around the plant’s roots to function. These micro-organisms are as intricate to the growing process as any other variable. The plant’s symbiotic relationship with micro-organisms has developed over millions of years of evolution. Although scientists have not figured out exactly why, the micro-organism symbiotic relationship regulates nutrient uptake in a way that has a direct influence over the growth rate and the quality of the fruit or flowers. Conventional fertilizers bypass the network of micro-organisms in the root zone. Chemical fertilizers are broken down into a form that is readily available for nutrient absorption. They don’t require the complex chain of events unfolded by micro-organisms and the enzymes they produce to break down organic matter into a soluble form. It is the bypassing of these micro-organisms that gives conventional gardening techniques the increased speed of growth it proudly boasts. This increased speed of growth can sometimes lead to larger yields. In most cases, as the speed of growth increases, the quality of the product decreases. Flavor, aroma and, in some cases, nutrient value are degraded in order to boost production to the maximum level. In extreme cases this method of horticulture will quickly produce large yields of tasteless products void of nutrient value. It is this output of substandard products being supplied by large scale commercial growers that has indoor horticulturists growing their own and leaning toward organics.

There are now various organic certification companies devoted solely to determining if the horticultural products submitted to them are, indeed, certifiable organic. These companies will analyze the product’s ingredients and, in some cases, the method used to extract an ingredient. Then, based on standardized federal requirements, these companies will certify the product as organic. The reason for the growing number of organic certification companies is a direct result of supply and demand. There has been a continually increasing demand for organic products over the last 10 years and it doesn’t seem to be slowing down. This demand from customers drives fertilizer and soil companies to produce more certifiable organic products, increasing the need for more certification companies.

Implementing organics

Some growers are interested in organic gardening but do not know how to make the transition. Regardless of the style of gardening currently being used, growers can begin to convert their gardens by implementing organics. Some changes are easier than others and can be introduced immediately. Other transitions can take a longer period of time or might require slight modification to the growing system to function properly.

Soil

If you build your own soil, be sure that all of the individual ingredients are, in fact, organic. Look for organic certifications or contact the manufacturer directly to verify the ingredients. The same goes for purchasing a pre-made potting soil. Many soil companies are getting their soils certified organic just like the fertilizer companies, making it easier for the consumer to purchase organic potting soil. Never assume a pre-made soil is organic just because it’s a soil. Unfortunately, most potting soils sold at home improvement centers or grocery stores are not organic potting soils. They can contain a variety of chemical additives. If the soil is not certified organic, the best thing to do is to closely examine the ingredients lists. If it contains ingredients that you cannot pronounce, assume it is not organic. Also, be aware of hidden ingredients. Some soil companies will hide the chemical additives in the ingredient list as a “starter nutrient charge” or something similar.

“If the soil is not certified organic, the best thing to do is to closely examine the ingredients.” All organic nutrients are compatible with soil. This makes for an easy transition to organics for any soil gardener. Most large fertilizer companies will have all of their organic products certified by one of the various organic certification companies. This is great for organic consumers, who can walk into their local indoor gardening center and instantly determine which products are organic. Some of the smaller fertilizer companies might opt out or not be able to afford the certification process but still produce a quality, organic product. In this case, a closer look at the ingredient list is the only way growers can determine if the product suits their desires. As with the soil ingredients, if you cannot pronounce it then it probably is not organic.

Hydroponics

Converting a hydroponic garden to organics depends on many variables. Because organic nutrients tend to have more sediment, operating particular hydroponic systems may be troublesome. Aeroponics and top-feed hydroponic systems are most prone to problems caused by excessive sediment. Clogged emitters or feed lines can be a common occurrence in these systems if the system’s pump lacks the proper filtration device. Additional filters for the submersible pump are recommended for any hydroponic system utilizing organic nutrients but are absolutely necessary in aeroponic and top-feed systems.

“Additional filters for the submersible pump are recommended for any hydroponic system utilizing organic nutrients.” Recirculating hydroponic systems can pose additional problems when using organic nutrients. As plants (more specifically the micro-organisms in the root zone) break down organic matter the pH will fluctuate and the nutrient concentration will change. It could be difficult to make adjustments to the nutrient concentration in the reservoir because electric conductivity cannot produce accurate readings with organic nutrients. This creates a sort of guessing game for the gardener regarding their nutrient strength. In my experience, the best way to implement organic nutrients into an existing hydroponic system is to do so gradually. In other words, start with one organic additive and see how it affects the system. After you feel comfortable with one additive try another and so on and so forth. Eventually you can attempt to switch out your base fertilizers for organics. Many growers do not completely switch to organic but find a hybrid nutrient cocktail that gives them some of the benefits of both worlds.

“Beneficial insects can be an organic gardener’s greatest ally and act as an effective first line of defense.” Pest control

Pest control is an area where any grower can immediately make the switch to organics, especially now when the technologies to extract the active compounds have accelerated the effectiveness of organic pesticides to the equivalent of their chemical counterparts. Beneficial insects can be an organic gardener’s greatest ally and act as an effective first line of defense. When the pest insect has built a tolerance to chemical insecticides, beneficial insects are the most effective control. A bug cannot build a resistance to being eaten.

Conclusion

As our knowledge increases even further regarding the complex, microscopic world that affects the quality and performance of our indoor gardens, the increasing desire to work in tune with these microbes is inevitable. Organic gardening techniques allow the horticulturist to work with these valuable, invisible assets that we are still trying to completely understand. Even without a full understanding, we know that by transforming even a portion of the garden to organics, a grower can help the environment, instill safety at home, increase quality and, all the while, allow nature’s incredibly designed symbiotic relationships to function in the way they were intended.

IPM

for Small-scale

Growers

by Raquel Neofit

The buzz word in the horticulture industry these days is IPM, or integrated pest management. But what exactly is IPM and is it a viable option for the hobby or home gardener? Integrated pest management (IPM) steers away from the line of hard-core chemicals to kill detrimental bugs in favor of natural predators (biological controls), soft insecticides (preferably organic-, oil- or soap-based products) and baiting and trapping (like sticky tapes and pheromone traps) to control crop pests. According to Tony Bundock of the National Precision Growing Center, there is evidence of IPM from way back in 2,500 BC when Sumerians used sulfur compounds to control insects and mites. The modern form of IPM gained popularity in late 1960 and has been developed into a major crop management toll for commercial horticulture. I like to call IPM the bug-eat-bug method, but you should also consider the other factors recommended by this method of pest control. First, you need to identify which bugs are bugging your local area on a regular basis, then, determine the level of infestation that is likely to occur. Perhaps sticky traps combined with a soft insecticide will do the job for you. But, if you do find the problems are slightly bigger, then maybe introducing a low level of beneficials will be a more cost- and time-effective solution. 92

Maximum Yield USA | April 2013

For large-scale growers, implementing an IPM program can be a complex and daunting project; however, for the small-scale grower, you might just see quicker and more economical results.

Here’s a quick looks at the pros and cons of IPM on a small scale: Advantages • Reduced risk of chemical contamination to people, produce and the environment • Slows the development of resistance to pesticides • Pests do not develop resistance to beneficials • It’s a step closer to organic agriculture practices • It’s also a step closer to sustainable agriculture practices Disadvantages • There is a higher level of education and knowledge required. We need to understand the interactions between good and bad bugs and who is whose predator • In large-scale growing situations, the good bugs have a better chance of multiplying because there are many more of them to begin with than in a smaller area; therefore, they leverage greater control over a larger environment • Beneficial bugs really need to be introduced to your garden before the pests infiltrate • If you grow a whole range of crops, you might require a whole range of different beneficials, as different bugs are attracted to different crops. Thus, this can become expensive

COST FACTORS

IPM looks expensive from the out-set, but by the time you take into consideration the cost of harsh chemicals and the time and labor used to treat an infestation, the results can be very cost-effective. Tony Bundock believes we should look at the cost as an investment rather than an expense because the beneficial bugs work tirelessly for you day and night. He suggests finding a large-scale local grower who might sell you beneficials from their commercial supply.

A FEW CONSIDERATIONS

Here are a few things to keep in mind if you decide to travel the IPM road: • You need to be able to identify the bad from the good • You need to know what bugs are circulating your crop and which bugs are their natural predators • You need to introduce the beneficial bugs before major problems occur • You need to know the level of tolerance your crop has to any given bug • And you need to find a local biological control agent to assist you when you need predatory bugs or advice The principle of IPM is about taking control over the whole season rather than just a week or two. Remember that the true benefits of an effective IPM program lie in introducing the beneficials early and not waiting for an infestation.

“ The principle of IPM is about taking control over the whole season rather than just a week or two.” As with every greenhouse endeavour, do your research. Ask yourself, “Is IPM best suited to my area, my crops and the bugs that infiltrate my local area?” Seek out the advice of experts that can help you answer these questions; an informed decision is the best decision.

SIMPLY SILICA

Since plants

lack the immune system that animals rely on to stay healthy, silica helps perform many of the same functions and can be thought of as a super vitamin and an immune support for plants.”

Silica plays an important role in just about everything. It is one of the main components of the Earth’s crust; it makes up the sandy beaches that border the oceans of the planet; it lies in the veins of quartz crystal that course through granite boulders; it is used to make the glass products that we use in our everyday lives on a regular basis. Silica, often renowned for its rigid properties, is also an important component of the plant kingdom, a jack of all trades, if you will, in the horticulture hemisphere.

What is silica?

Silica is the common term for the compound silicon dioxide. It is formed when silicon comes into contact with oxygen. Silica is abundant in many soils and is a major component of plant tissue, sometimes in even higher concentrations than nitrogen and potassium. Although vital to plant health, silica is not classified as one of the essential nutrients for plants in general, which can lead some growers to believe it is not necessary to add to a normal feeding regimen.

Maximum Yield USA | April 2013

What benefits does silica provide for plants? The list of benefits that silica provides to plant health is lengthy. Any grower who is serious about growing strong beastly plants should consider adding silica to their normal fertilization schedule. Some of the most important benefits are:

Stronger cell walls Silica can be compared to the likes of a liquid bamboo, virtually fortifying cells from the inside out. Cells are the building blocks of the plant’s framework. Strengthening the cell walls helps the plant build strong hearty branches and stems that are reinforced enough to support the weight of the fruit that the plant will eventually produce.

Stronger cells mean bigger stems Thicker cell walls resulting from silica use create bigger stalks and stems that can uptake and transport more water, nutrients and plant secretions throughout the plant body, facilitating faster growth rates and bigger plants.

Increased resistance to environmental stress Since plants lack the immune system that animals rely on to stay healthy, silica helps perform many of the same functions and can be thought of as a super vitamin and an immune support for plants. It contributes to areas such as: Climate: The addition of silica helps plants withstand extreme temperatures, whether hot or cold. This is especially helpful for outdoor growers that experience hot midday peaks or low temperatures at night. Drought: Silica forms a protective coating on an intracellular level that decreases the amount of water loss through transpiration, making plants less likely to suffer as dramatically during drought conditions. It also enables them to continue functioning during high-temperature or lowmoisture conditions and reduces the amount of shock they experience in such extreme cases.

SIMPLY SILICA

Plants grown

Increased resistance to pathogens When a plant is fed a soluble form of silica, the plant accumulates the silica around the infected site forming selectively fortified areas that can fend off fungal infections such as rust, pithium and powdery mildew. As a resistance measure, the plant uses the silica to build up an additional mineral barrier, essentially lining the cells, making it more difficult for diseases and pathogens to make their way inside the plant.

Increased resistance to pests Silica accumulates in the epidermal cell walls of leaves, making it harder for biting and sucking bugs to damage the plant. Deposits of silicic acid within the cells act as an additional barrier to sap sucking insects. Foliar feeding is the best way to ensure the silica gets directly absorbed into the leaves where it can be immediately used to combat pests.

Enhanced metabolic functions Plants grown with the use of soluble silica are shown to have higher concentrations of chlorophyll in their leaf tissue compared to plants grown without it. It also enables them to make more efficient use of CO2, resulting in lush healthy green foliage with excellent leaf structure and reduced amount of leaf wilt.

When should silica be used in the garden?

in soil are more likely to uptake trace amounts of silica that could be present in the soil, whereas plants grown hydroponically have no direct source of silica unless it is added as a supplement to the nutrient regimen.”

Studies show that silica should be used throughout the entire life cycle of the plant, from the seedling or clone stage up until harvest. In order to produce optimal results, silica needs to be continually made available to the plant via the nutrient solution. Once a plant has absorbed the available silica into its cellular structure, it can no longer be redistributed to other parts of the plant. Plants grown in soil are more likely to uptake trace amounts of silica that could be present in the soil, whereas plants grown hydroponically have no direct source of silica unless it is added as a supplement to the nutrient regimen. Plants grown hydroponically without silica will most likely be sub par compared to those grown with it.

Cuttings and seedlings that have been fed silica tend to show less shock during root formation and transplanting. Introducing silica early on in the plant’s life is also said to reduce the chances of leaf curl. Cut flowers also benefit from silica, as it has been known to extend flower shelf life. Have you ever added a powder sachet into the vase of water when you buy a bouquet of flowers? That is a nutrient mixture combined with silica!

SIMPLY SILICA

When one

product has a seemingly endless list of positive attributes, it’s a no-brainer that it should be put to use by growers that are serious about producing results.” How should silica be applied to plants?

It’s a good idea to follow the dosage rates of the particular product being used, but as a good rule of thumb, when plants are very young, introduce silica at about 20 to 30% of the general feeding rate and gradually increase the application as the plants grow in size and enter the bloom phase. Most silica products on the market can be applied as a root feed or as a foliar spray. Plants can absorb much more

through foliar feeding than just absorption through the root zone. Silica is also known to prevent powdery mildew when used as a foliar spray. If using silica as both a foliar and a root feed, be careful not to overdose the plants. Follow the feeding schedule according to the brand carefully before mixing the solution.

What else is there to know about silica?

Silica is alkaline by nature and therefore will naturally raise the pH level of your nutrient solution. It should be added after the other nutrients have been thoroughly mixed into the water. It is a good idea to dilute the silica in about one gallon of water before adding it to the reservoir to avoid nutrient lockout that can occur when it comes into direct contact with other elements in the solution. In many cases, silica could raise the pH level of the solution enough that the additional use of pH up will not be necessary.

What types of silica are the best?

Since there are so many brands of silica in the horticulture industry, it can be tough to decide which

100

Maximum Yield USA | April 2013

one to use. It is wise to choose one with a high concentration of silicon dioxide so that a little bit goes a lot further. There are brands that boast fancy labels and high-sticker prices but then only provide products that contain 3% or less concentration of silica. Look for brands that have at least 7 to 8% silicon dioxide. Liquid silica that is clear will be more soluble in the reservoir than those types that have a milky, chalky consistency. Remember to choose products that are free of dyes or colorants. In the world of hydroponics and gardening, the sheer amount of products on the market can be daunting. There are many secret recipes, mysterious formulas, cryptic ingredients and vague labeling to contend with. Once in a while it’s nice to fall back on a basic product that is easy to understand, is even easier to use and produces great results. When one product has a seemingly endless list of positive attributes, it’s a no-brainer that it should be put to use by growers that are serious about producing results. For robust crops and impressively healthy harvests, try silica as a super supplement in your next grow!

organic rooting medium Fresh wood by-products, such as pinebark, wood chips and course sawdust, are suitable for use in soilless organic rooting media mixes. Pinebark is a common ingredient in many peatmoss-based formulations. However, these wood by-products contain tannins that are toxic to plants. Therefore, composting is essential in order to remove this chemical, as well as other unwanted oxidizable substances. The time and method of composting varies with the product and composting conditions. For freshly gathered pinebark, wood chips or course sawdust, composting for at least a year under warm climatic conditions is required. Composting is best done outdoors, with periodic turning for equal exposure of the material to the climatic elements. Heat gener-

ated in the composting process might require cooling by watering during low rainfall periods, thereby keeping the compost pile from catching fire. Composting also stabilizes the physiochemical properties as the easily oxidizable components are eliminated, leaving a bio-stable organic structure. Following composting, the material will require milling and sieving in order to obtain a uniform, particlesized product, as well as removing the fines not decomposed during composting. The useful particle size range is between 0.02 to

Composting is also a concentrating process for elements that could reach a toxic level. Elemental accumulation will depend on what elements were in the initial composting materials. For example, manganese is present in pinebark at fairly high concentrations and, with a relative increase due to composting, can potentially reach a toxic level. Therefore, before use, the pinebark needs to be laboratory tested to determine its pH and elemental content. This test procedure is by water-equilibrium extraction, a test method not provided by all soil testing laboratories. Adjusting the water pH of pinebark to between 5.6 to 5.8 using dolomitic limestone is recommended. Since pinebark, wood chips and sawdust are natural plant products, they will contain some content level of all of the essential plant nutrient elements, some in sufficient quantity to provide that needed by a plant

rooted in it. Having the material assayed before use as described above, nutrient element supplementation can be done selectively by taking advantage of what elements already exist in sufficient plantavailable quantities. I have used composted milled pinebark as a rooting medium in both greenhouse and field growing of tomato, lettuce and other garden vegetables with great success. One of the interesting observations is that crop performance seems to improve with continued use, suggesting that stabilization of its physio-chemical properties is a long-term composing-use process. This method of growing works best using the subirrigation method. Before use, dolomitic limestone and 10-10-10 chemical fertilizer are mixed into the pinebark (Table 1). Similarly prepared pinebark as a rooting medium placed in pots for the growing of tomato and cucumber with delivery of water by drip irrigation has been used with excellent results. If a nutrient solution formulation is delivered by

SOF

R'S not that Hard!

Softened water is one of those “hate it or love it” things; however, regardless of which camp you’re in, knowing a little bit about water softener can help you better evaluate your water needs.

110

Maximum Yield USA | April 2013

soft water’s not that hard Softened water is a divisive issue. Like cilantro, two-stroke engines and Bon Iver, most people either love it or hate it. Proponents love the clean bathroom fixtures, superior lather of soap and laundry detergent and streak-free windows. Haters primarily dislike “that slimy feeling” softened water leaves on the skin and the added salt, which requires a point-ofuse filter for drinking water and plants. Regardless of which camp you’re in, knowing a little bit about

“when people did their laundry by hand, they found that heavily mineralized water made it hard to wash clothes—hence, hard water.” water softeners can help you make an informed decision when evaluating your water needs. Softeners look a little like an oxygen tank, are available in several sizes and can use either sodium chloride (salt) or potassium chloride as a medium. They work by exchanging the hardness (that is, minerals) in water for either sodium or potassium using cationic exchange. Hardness is measured in “grains;” the more grains of hardness present in the water, the higher the salt or potassium content of the softened water. Gardeners who use a reverse osmosis (RO) filter to prevent nutrient lockout of their plants might want to add a softener before their system to reduce hardness and help extend the life of their RO system.

It all comes out in the wash

Soft water is so named because it isn’t hard. In researching this article, I came across the Water Quality Associations’ (WQA) reason for the designation of “hard” and “soft,” which is this: years ago, when people did their laundry by hand, they found that heavily mineralized water made it hard to wash clothes—hence, hard water. Apparently, their solution was to collect rainwater to wash with, which was referred to as soft. This might seem like a lot of trouble to go to for the sake of washing a few dirty clothes, but check this out: the WQA also cites a Purdue University study that found clothes washed in hard water wore out 15 times faster than those washed in softened water. This statistic is attributed to the way that suspended minerals simply rub on clothing fibers and wear them out, which seems somewhat obvious. Apparently detergent is another factor. Laundry soap was originally highly alkaline, which helped to create a water environment in which dirt was easily released. As people got tired of saving rainwater for their laundry, their laundry soap wasn’t working very well to wash their clothes. Soapbased cleaners combine with hard water to create what is somewhat disgustingly called soap curd. This unappealing substance is a combination of soap and hard-water minerals, and is what ends up coating your shower door, bathroom fixtures, etc. It’s also hard on fabrics. Enter detergent. 112

soft water’s not that hard

Detergent was developed as a petroleum product and dissolves nicely in hard water. This is helpful when doing laundry, but not so helpful for the planet. Many people are doing their best to avoid petroleum products whenever possible, and synthetic detergents are not nearly as biodegradable as their soapy predecessors. If you cringe at the price of clothes these days, remember that wearing out those skinny jeans 15 times faster can really add up. As innocuous as doing laundry might seem, the effects of hard water can impede the process of cleaning your clothing, towels and linens, which costs money. Although synthetic detergent mitigates some of the soap curd (gross) associated with laundering in hard water, the best solution is to simply use a water softener. Once used, a return to traditional laundry soap will help keep your clothes clean and the planet happy, or synthetic detergents can be used in much smaller amounts than before, saving more money. Hot water use will decrease, as the soap will do an excellent job in cool water, saving on energy costs. Additionally, using a water softener ensures that your skin will no longer be repository for soap curd residue.

Slippery = clean?

That’s right; soap curd is responsible for that squeaky clean feeling on skin and hair… maybe. The lack of squeak, the feeling that maybe the soap hasn’t rinsed entirely off, is one of the most controversial effects of softeners. According to some, the slippery feeling skin gets in softened water is a result of the ionic exchange that occurs when mineral content is exchanged for sodium or potassium (depending on which media is used in the softener) and the resulting ions keep the soap from sticking to the water and getting rinsed off. Sounds pretty legit, but check out the internet for any water softening company and the explanation changes. These companies claim that the slippery feeling is actually the way that clean skin feels without the rubbery squeak of soap curd. Both sides acknowledge that since soap works much better in soft water, people sometimes use the levels they used in 114

hard water—much more than is necessary in soft water. It’s a tough claim to parse, as rinsing a soapy sink in softened water leaves no hint of curdy ring, which points to superior rinsing ability and the claim of the makers of softeners. Then again, rinsing in naturally soft water like rainwater or water softened by other means like RO, both of which wouldn’t contain which added sodium or potassium, doesn’t seem to cause any sort of slimy skin-feel, regardless of soap. I failed to find any third-party study which actually measured soap residue left after a softened water rinse verses a hard water rinse. Anecdotally, some users of softeners rave about the improved condition of skin and hair without soap or mineral residue when using a softener, while others bemoan the drying effects of softened water on their person. When it comes to the skin/hair debate, it might just be a matter of preference. Personally, I hypothesize that it might very well be the way that the sodium/potassium ions feel on the skin, not necessarily that soap is being left behind.

soft water’s not that hard

But how does it taste?

The WQA, along with softener companies, claim that unless one is on a severely salt-restricted diet, the added salt in softened water isn’t a health risk, with an average of about 0.02 oz. of added sodium per gallon of water. While this amount is about one-fifth of the sodium in skim milk, I’d be more concerned with taste. In my humble opinion, the drinking water that tastes the best is water that has been filtered using RO to take 96 to 99% of all contaminants

“ Using a remineralizing post filter is an easy solution that adds minerals your body can use and allows RO to remove many other harmful contaminants.” out, and then treated with a remineralizing post filter to add back about 30 to 50 ppm of calcium carbonate for that clean, crisp taste. Drinking water that has been demineralized (whether by an ion exchange softener or RO) is another source of controversy, some claiming that it strips the body of its own minerals, and others pointing to the fact that many dissolved minerals on water are too large to be absorbed by the body. Using a remineralizing post filter is an easy solution that adds minerals your body can use and allows RO to remove many other harmful contaminants. An added benefit of using a softener is that it acts as excellent pre-filtration for a RO drinking water or plant water system, preserving expensive RO membranes and saving you money! 116

soft water’s not that hard

What about the plants?

Let’s be clear—sodium-chloride softened water should never be given to your plants, especially in a hydroponic garden, as plants are very sensitive to levels of sodium. Some outdoor gardeners who have a whole-house softener might choose to use potassium chloride media, as the relatively low levels found in softened water are not generally harmful for lawns and other non-sensitive plants. However, hydroponic gardens can also be disrupted by excessive potassium. A softener can, however, benefit your plants in much the same way it can benefit your drinking water—as a pre-filter for RO. Reverse osmosis has become the gold-standard of water treatment in hydroponics, removing blocky, unusable minerals, heavy metals, volatile organic compounds and a host of other toxic contaminants and preventing nutrient lockout. The most expensive parts of a RO filter are the membranes—and those with large gardens using lots of water know that replacing those membranes can add up. Incidentally, the very hardness that prompts many gardeners to purchase an RO system is the same hardness that can prematurely clog the RO membranes. Since softeners exchange that damaging hardness for sodium or potassium chloride, the membrane’s job is much easier. Both sodium chloride and potassium chloride are easily removed by RO membranes, which will remove 99% of sodium or potassium chloride.

“ sodium-chloride softened water should never be given to your plants, especially in a hydroponic garden, as plants are very sensitive to levels of sodium.”

Bottom line

The bottom line is that if you have hard water, you should probably get a softener. Whether or not you use the softened water for your whole house, for your shower or just to preserve your RO membranes in the greenhouse is a matter of preference. The money it can save you in the laundry room and the garden is undeniable. Don’t worry, you can still hate cilantro, but now you can spend less money growing it by using a softener to assist your RO system.

TOSS aside

the notion, if you will, that there is not one single agricultural crop cultivated commercially that is grown solely using artificial lighting.” For just a moment, forget about the immense amount of electricity that is used to grow plants strictly under lights. Forget about the fact that no bulb can replicate all the properties of the sun. Remove the fact that the high cost of building an indoor growroom still leaves you dependent on either your local electric company or a fuel consumptive generator in order to run all the grow lights and fans. These costs become so high that you might as well consider your local meter reader as a very silent partner that receives 20 to 40% of your harvest. Toss aside the notion, if you will, that there is not one single agricultural crop cultivated commercially that is grown solely using artificial lighting. Don’t even consider for a moment the environmental impact from bulbs that are improperly, or even properly, disposed. Now that we have stripped away some of the potential downsides to indoor cultivation, let’s consider some of the benefits. One benefit is security. Not only is your crop protected from unwanted visitors by a solid wall and a door, but you have complete control over your grow zone in other ways too. This would include the control of the lighting schedule, which empowers the grower to determine the flowering schedules of their plants. This allows for optimum efficiency of crop production throughout the year and allows the farmer the ability to bring product to market whenever they choose, often dictated by seasonal demands.

Greenhouses offer

Most often when people think of greenhouses, they think of a wooden structure clad with old yellowing plastic or a mega gutter-connected greenhouse that covers acres of farmland with millions of dollars of investment glistening in the summer sun. These structures might leave you feeling a little disheartened or with a feeling that a greenhouse for your own yard is out of reach. However, there are greenhouse companies that specialize in customer service and making sure that you have the right fit for what you are looking for. Specifically, in our scenario, you need a greenhouse company that specializes in light deprivation. Light deprivation techniques allow you the ability to step into the same game as an indoor grower while receiving all the benefits of greenhouse growing. Light deprivation is the ability to cut out sunlight from your greenhouse when you require extra hours of darkness to flower your plants while the outdoor light cycle is still in a period of vegetative growth. Whether this is done with an automated light deprivation greenhouse or done manually by pulling tarps of a breathable blackout fabric, the end goal is the same: a consistent amount of required hours of light and of darkness, making your plants think it is fall and the end of their life cycle is approaching (therefore causing them to flower so as to continue the reign of their species). A greenhouse company that specializes in light deprivation will have the knowledge of how to work most efficiently and effectively throughout the different seasons within your greenhouse. As I mentioned earlier, greenhouses have traditionally been used to extend your growing season early in the spring and

up the control that indoor growrooms provide, as well as giving the plants the full spectrum of the sun that will increase the plants’ nutritional aspects and will dramatically increase your yield.” Humidity and wind velocity are also all easily controlled by fans that are monitored by an automated environmental control panel. Temperature is controlled as well, so the outside climate has little to no effect (in the heat of the summer, the room is often cooled by air conditioning units, and winter-time lows sometimes see the need for heating units to keep the ambient room temperature up). Though all these benefits do lend a sense of bling to crops grown indoors, it does leave open the conversation of what might be missing in a photosynthesizing plant that is using a bulb and not the sun for its main source of life force. Enter greenhouses. Greenhouses offer up the control that indoor growrooms provide, as well as giving the plants the full spectrum of the sun that will increase the plants’ nutritional aspects and will dramatically increase your yield. Traditionally used to extend your growing season through the cold of the off-season, greenhouses are now also being utilized with remarkable benefits during the rest of the year. Indeed, greenhouses can be used efficiently with ease and security by anyone with a green thumb and attention to plants.

late into fall and even potentially through the winter months. This, however, does not address the harshest climate to deal with a greenhouse. The summer heat can become unbearable in a greenhouse that hasn’t been properly set up. Solar gain is the term used for the increase of heat in a greenhouse from the inability to properly ventilate the space. A properly ventilated greenhouse will not exceed the temperature outside and will therefore not have much, if any, solar gain. Proper ventilation can be achieved through exhaust fans or with passive cooling. When using fans, make sure to calculate the cubic foot dimensions of your structure and match it with fans that can exchange that air about every one to three minutes in the hotter parts of the year and two to four minutes for the rest of the year (cubic feet per minute [cfm] is the term the fan will use in determining how many cubic feet the fan can exhaust in one minute). I prefer to use a dual fan/ dual intake louver system so that the temperature and humidity can be controlled in stages. Also, take note that exhaust fans only work properly in a sealed environment; so, while leaving a door open or rolling up a sidewall might intuitively sound like a good idea, it isn’t always. The fan will exhaust air from its closest location, so if there is an opening in the structure close to the fan, the fan will take the air from that point and not pull the air across the whole structure. A greenhouse grower also has the ability to supplement the desired hours of light and warmth for the plant during the colder, darker months

This can be done at a drastically reduced cost when compared to indoor growing because of their ability to use the sun. Though the amount natural lighting might not be sufficient, you’ll only need a few hours of supplemental lighting in the beginning or end of the day in order to meet your daily quota of light and darkness. On cloudy days, lights can also be used to increase the intensity of the light allowing plants to stay in optimal conditions. As an added bonus, the winter sunlight also adds heat to your structure, thus reducing the need for a complete heating source. Many people heat their structures with overhead forced heat, although the more efficient and effective heat comes from the bottom up. By heating the root zone, the most important part of the plant to stay warm, the heat will passively rise up through the canopy and start heating the rest of the empty structure (instead of starting in the empty zone of the structure that has a high level of heat loss). This methodology can save thousands of dollars in heating costs. This bottom heat is usually done with water-based radiant heat. A solar collector, a passive method of heating water from the sun, can be installed in the loop to heat the water before the

boiler needs to expend energy heating the water on a cold but sunny day, saving you even more on utility expenses. When looking at the methods of light deprivation, consider a high-quality polyweave, not film, covering that has the correct amounts of UV stabilization and the ability to diffuse light. These qualities in a fabric do a couple of things, most obviously is in the appearance of your finished product. These fabrics were designed for the flower industry and the filtration causes plant resins to pop and wind up resembling plants that were grown strictly under lights. Also, the UV stabilization filters out the harmful intense spectrums of the sun that heat up your structure and your plants. As such, this material lowers the temperature of your soil, causing less need for water and giving more optimal conditions to your soil microbes. It also reduces the temperature of the surface of the leaf, which is one of the biggest benefits. The advantage to this is on hot summer days when plants outdoors are putting a lot of energy into transpiration, staying cool and survival, while the plants inside your greenhouse are putting their energy into photosynthesis, growth and flourishing. Another bonus of greenhouse gardening is that you can use any system of growing that you would indoors—hydro, in bags, on tables, in beds, on a trellis system or vertical the greenhouse structure is going to allow you to take what you’ve mastered and step it up to the next level in efficiency and production. So, in a greenhouse, you can grow your plants like you would indoors, but at a fraction of the cost. Greenhouses excel in efficiency and offer a more complex finished product. In a greenhouse, you have the ability to cultivate plants efficiently with indoor quality and outdoor quantity while greatly reducing your overhead and environmental impact to do so. So, go green and go outside while still being indoors—go into a greenhouse!

HIGH-TECH PROPAGATION

Ever since the dawn of agriculture, plant propagation techniques have been under intensive study. Without reliable methods of plant multiplication we would have no crops to harvest and no way of creating future generations of improved genetic stock. While the basic principles of plant propagation have been understood and used for centuries, these days we have a whole host of new technology, equipment, products and knowledge that have made vast improvements in the reliability and speed of this process. Furthermore, researchers are still delving into many aspects of plant multiplication and uncovering new information to further improve the process of propagation of a wide range of species. As indoor gardeners we have a major advantage when it comes to propagation. With precise control over the environment, heat, humidity, light, oxygenation, CO2 and other factors, propagation becomes a more reliable process. Couple this with advances in hydroponic equipment and products specifically designed for the nurturing of new plants, seed production and treatment technology, and knowledge of root formation compounds, hydroponic growers have all the tools required for successful propagation.

Based on

produced on stolons and others. However, the majority of vegetable and herb species we grow hydroponically are produced via seeds and cuttings. The advantage of cuttings is that the resulting new plant will be genetically identical to the motherplant the material was taken from. This means all the good characteristics of the plant are retained and we know exactly what to expect in terms of growth and yields from the propagated plantlets. The disadvantage is that pests, diseases and viruses carried on the motherplant can be transferred to the daughter plants. Cuttings also require a motherplant to be maintained in a healthy state for cuttings to be taken from, so genetic material can’t be stored for extended periods of time in the way that seeds can. Cutting material, depending on species, can take anywhere from a few days to many months to form new roots, although most of the species grown indoors are relatively quick to do so. Cuttings are often a preferred way of multiplying plants that are very slow or unreliable from seed. For example, a stem cutting of mint will form roots in water in a few days, whereas the tiny seeds take many weeks to produce a seedling large enough to plant out. Seeds have the advantage of being small, portable and easy to store for a relatively long period of time. Most vegetable and herb seed germinates quickly, within a few days for most, and commercially produced seed usually has a very high percentage germination rate. Hybrid seed will have uniform genetics and have been bred for adventurous characteristics. However, open pollinated seed will not produce new plants identical to the parents. As you can see, genetics can be fairly random when hybrid seed is not used.

Cuttings or clones? The technology Some softwood species will easily root quickly, often in a jar of water; however, most species we want to clone benefit from some assistance, care and attention. After carefully selecting and preparing the cutting material from a healthy stock plant, a root promotion product should be applied. Back in the old days, there were just basic powders or solutions of an auxin

Based on extensive research into root promotion compounds, rooting gels now contain not just IBA or NAA, which are auxin plant growth regulators, but also other stimulants and bioactive compounds shown to be beneficial for this process.

136

Maximum Yield USA | April 2013

Auxin (IBA and NAA) are plant growth regulators that stimulate root development by inducing root initials that differentiate from cells of the young secondary phloem, cambium and pith tissue of the cutting material. IBA is most commonly used in these products as it is relatively stable and doesn’t break down due to enzymes within the plant. It’s well proven that use of a product containing an auxin such as IBA increases the percentage

of rooted cuttings, the number of roots and the speed of root formation. However, advances in plant research over the last few decades and even quite recently have also discovered other root formation substances which are synergistic with IBA. Since the 1950s, it’s been known that boron is essential for the development of adventitious roots on stem cuttings. Many researchers have found that whereas roots are initiated in response

Thiamine (vitamin B1) is another root promotion substance in cuttings of many species. Studies have shown thiamine assists with promotion of rooting in terms of speed and number of roots formed. Many highly effective hydroponic rooting gels and other products contain boron, thiamine, humic or fulvic acids and a host of other vitamins, minerals and bioactive compounds that might be beneficial to root formation on cuttings. More recently we have seen a range of microbial products being developed specifically to help promote root formation on cuttings and young seedlings. These microbial products are not new—the beneficial effect of mycorrhizal fungi on rooting of woody plant cuttings was reported in the 1970s; however, its only more recently that shelf-life stable and effective products have been available for smaller growers to purchase. These plant growth promoting rhizobacteria are thought to enhance root development either directly by producing phytohormones, or indirectly by inhibiting disease pathogens. Along with increasingly effective rooting promotion gel products and bio stimulates, advances in propagation substrates and systems have seen sometimes miraculous improvements in percentage germination and cutting take rates. Root formation and germination are highly reliant on the correct environment, as well as freedom from certain pathogens such as pythium and other root rot diseases. Sterile, highly aerated propagation media such as oasis, rockwool, foam substrates, coconut fiber, vermiculite and many new types of starter cubes are a vast improvement on trays of sand and peat historically used for propagation. Many of these new mediums have been created with specific air-to-water ratios to boost oxygen around the newly forming root initials or germinating seed. Other new propagation products are highly specific to hydroponics and include a wide range of

138

different sized propagation systems– often termed cloning machines–that mist highly aerated water and nutrients inside a chamber, maintaining the optimum environment for root formation. These types of systems are particularly useful for harder wood cuttings and difficult on root species as they speed up the rate of root formation.

Seeds: the technology Just as with cuttings, seed germination has also seen some advances in technology and specialized materials. Most hydroponic gardeners these days raise seedlings in specially designed propagation mediums. These can be sterile foams, rockwool, oasis or any of wide range of synthetic materials or more organically based mixes of coconut fiber, composts and propagation cubes made from a bound matrix of these materials. As with cuttings, there are a range of bio stimulant products for seed germination and seedlings, including those based on humic and fulvic acids, vitamin and minerals and microbial inoculants. Along with a suitable germination medium, growers can utilize a range of propagation equipment from the easy to use heating pad to an enclosed germination chamber, which maintains the right degree of heat, humidity and light once the seedlings emerge. Seed technology itself has also improved in modern times. Many small and difficult to handle seeds, such as lettuce, can be purchased in pelleted form. For species such as lettuce, thermo pelleting assists the seed to germinate in a wider range of temperature conditions, while other seeds can be coated in growth promotants or fungicides to help control pre- and post-germination rot pathogens. Other seeds might be primed to promote rapid germination and most are viability tested before they are sold.

Cheap ‘n’ Easy Starts:

How to Germinate Seeds at Home by Heather Rhoades

Buying plants is expensive, but if you learn how to germinate seeds, you’ll never have to worry about spending too much for plant starts again.

Maximum Yield USA | April 2013

Many people will tell you that one of the most expensive parts of gardening is buying the plants. The best way to avoid this problem is to simply grow your own plants from seeds. Once you learn how to germinate seeds, you will always be able to have cheap plants. It is easy to get started with cheap seed starting.

How to germinate seeds Start with seeds that are less than two years old, a soilless seed starting medium of some kind and a container that can help hold moisture in. A soilless seed starting medium will insure that the seeds and seedlings are not killed by too much salt or salinity (frequently found in soil or even regular soilless mixes). The soilless seed starting medium can be an actual soilless seed starting mix from your local nursery, or a folded paper towel. If you choose to use a paper towel, you will need to move the germinated seeds to soil or another growing medium after they have sprouted. This container you select should hold in moisture. A plastic container is ideal for this. Some people might use a Tupperware container while others might use a Ziploc bag. The next step is to dampen (but do not soak) the soilless seed starting medium and place it in the container. This will ensure that the seeds continuously receive the appropriate amount of moisture. Now, find a warm place to put your seeds. Warmth is another important factor that affects seed germination. Many people find that the top of their refrigerator is ideal, but you can use a

“The most commons

factors that affect seed germination are moisture, salinity and heat.”

heating pad set very low or even the top of your TV. Anywhere that has a very low, steady heat. You should always keep your seed germination container out of direct sunlight, even if the package specifies they need sun to germinate. If you need the sunlight, place in indirect light. Check your seeds often to see if they have sprouted. Germination time for seeds varies and should be marked on the seed packet. Once they have sprouted, vent the container by opening it a little bit. If using a paper towel, move the seedlings to proper soil, otherwise transplant seedlings when they have two true leaves.

Factors that affect seed germination The factors that affect seed germination vary from plant species to species, but there are a few that are standard. The most commons factors that affect seed germination are moisture, salinity and heat. If the seeds you are growing are not germinated in what is considered a standard way, the seed packet will state this in the directions. Contrary to popular belief on how to germinate seeds, sunlight is not a standard factor that influences seed germination (unless otherwise stated on the seed packet). In fact, sunlight can do more harm than good as it might overheat the seeds and seedlings and kill them. Now that you know how to germinate seeds and you can do cheap seed starting, you can grow your own cheap plants!

Lights

: & CO2 Pros & Cons by Matt LeBannister

CO2 enrichment can dramatically improve your overall grow, but did you know that your choice of lighting can affect this process? 144

Maximum Yield USAâ&#x20AC;&#x201A;|â&#x20AC;&#x201A;April 2013

Carbon dioxide (CO2) is a hugely important component in the process of photosynthesis and therefore, overall plant health. This is especially so with rapid growing plants. There is roughly 300 to 400 ppm of CO2 in the air we breathe and these rapid growing plants can use that up very quickly. Grow can dramatically slow when the CO2 levels drop below 200 ppm. Enriching your growroom to 1,200 to1,500 ppm of CO2 is the logical next step to improve plant development. At this range plant growth is accelerated as much as two to three times and crop yields can be increased by 20 to 30%. For CO2 enrichment to be effective one must have all other aspects of your indoor garden running perfectly. One main factor that I have been asked about recently is lights and which style of lights are the best for gardens utilizing CO2 enrichment. Here I offer some pros and cons regarding the most popular types of garden lights. Just keep in mind much of this is based on personal opinion. Each of the following varieties will do the job, some just better than others.

Fluorescent Fluorescent light bulbs come in a number a varieties. The most popular for gardens are the newer T5 high output bulbs. They usually come in banks of two or more and are generally 2- to 4-ft. long.

Pros There are benefits to gardening with fluorescent light bulbs. The create very even lighting and can be positioned all around the garden, even vertically. And can be placed very close to the leave canopy. They are low wattage and will save you some money on your electricity bill and are low heat.

Cons The fact that they are low heat can be a bad thing when enriching your growroom with CO2. Plants benefiting from CO2 enrichment can tolerate higher temperatures and actually prefer it. A room temperature of 85ºF will boost the metabolic rates of the plants and speed up growth. Rapid growing plants, especially those be boosted by CO2, need as much light as possible. Fluorescent lights, even T5s, are not intense enough to really maximize the benefits of the extra CO2.

HIDs

need annual replacement to maintain high lumen levels and spectrum.”

Replacing fluorescent bulbs and changing them for different stages of growth, i.e., bloom and vegetative, can be costly. After a year of use the lumen output of these bulbs will have dropped dramatically. In my opinion, fluorescent bulbs are not ideal when enriching your garden with CO2.

LEDs LED stands for “light emitting diode.” They are relatively new to the market and are no doubt the future of indoor gardening.

Pros LEDs use an extremely low amount of electricity. They also give off next to no heat and can safely touch the leaf canopy without the risk of burning. LEDs can also last upwards of 10 years without requiring replacement.

Cons There are downsides to using LEDs in CO2enriched gardens. LED light fixtures are not really available in larger sizes yet and most CO2enhanced gardens are at least 10 by 10 ft. It is really hard to regulate the amount of CO2 in a space any smaller than that and most LEDs on the market today are really only suited for 4 by 4 ft. spaces. The spectrum on most LEDs are neutral and not interchangeable for the bloom and vegetative stages of plant growth. LEDs are also very low heat which, as mentioned with the fluorescent, can hinder plant growth. There is no doubt in my mind that LEDs are the future of indoor gardening and will

146

Lights and CO2

someday replace all types of gardening lights, but right now I feel like they are still unproven. That, coupled with their lack of heat and intensity mean they are not ideal for CO2-enriched indoor gardens unless they are set up in large arrays.

HIDs High intensity discharge (HID) is a broad term for metal halide (MH), high pressure sodium (HPS) and mercury lamps. They come in a variety of strengths and spectrums.

Pros One-thousand-watt HID bulbs can cover an area as large as 8 by 8 ft. or higher. You can interchange MH bulbs for the vegetative stage of plant development and HPS for the bloom stage of plant development, thus maximizing the PAR watts within each spectrum. This is also cost effective by comparison versus fluorescent bulbs especially when you consider the digital ballasts available that can fire both MH and HPS bulbs. HID bulbs do give off considerable heat, but this can be beneficial for plants being enriched with CO2 as they do best around 85ºF.

Cons High levels of heat can be detrimental if it causes evaporation of the nutrient solution in your reservoir. This can cause the nutrient levels to become too concentrated leading to nutrient toxicities and leaf burn. One must be vigilant and constantly check and maintain the ideal nutrient to water ratios.

HIDs do need annual replacement to maintain high lumen levels and spectrum. In addition, they are high-wattage lights so you will spend more on electricity than the previously mentioned alternatives. In my opinion, HIDs are still the go-to light when enriching your garden with CO2. They are tried and tested, have the heat the plants will crave and are intense enough to efficiently cover larger areas. All of these lights will work fine when adding CO2 to your garden. My choice of HIDs over fluorescents and LEDs is largely based on personal opinion and anecdotal evidence. Don’t be afraid to try things out for yourself or consult your local hydroponic retailer for their expert opinion.

Considering

Organo-chemical Culture

If you cherish the principles of organic agriculture, or are someone who has long considered switching to a more organic form of growing but do not want to sacrifice any yield because of it, perhaps the method of organo-chemical culture will spark your interest… Chemical fertilizers, as the green revolution so pointedly revealed, have a greater capacity to maximize yields in a given amount of space. Some studies have suggested the difference in commercial agriculture—specifically with vegetables requiring high concentrations of nitrogen— can be as much as 34%. However, in attempting to achieve a high-output system by utilizing only chemical fertilizers can (and, in most cases, does) bring with it an array of potentially damaging consequences: lockout, acidic soil, loss in microbial activity and decreased resilience to disease and mildew, to name a few. Furthermore, providing a nitrogen-heavy plant with the all required N-P-K through chemical means will ensure no deficiencies in heavy compounds, but might create other deficiencies in trace elements, reducing quality and potential yield. In contrast, it is proven that citrus grown organically has more secondary plant compounds and vitamin C than citrus produced with chemical food, while organic corn has more protein and organic kiwi has more antioxidants.

150

Maximum Yield USA | April 2013

So, with all this in mind, is it possible to utilize the short-term benefits of chemical fertilizers while avoiding their negative effects? Or, worded differently, is it possible to use both chemical and organic feed to create some sort of reciprocal balance? This is exactly the logic behind organochemical culture. And the results have proven exceedingly positive. The easiest way to employ the principles of organo-chemical culture is to equip your growing medium with a few basic necessities of organics. For instance, adding worm castings (or bat guano) to your soil will provide a healthy amount of trace minerals, natural N-P-K and humic acid to increase the nutrient availability in the soil. This also enhances the organic matter (bio-humus) necessary for better water retention and pH buffering. To buffer the pH even further, lime can also be added. Ancient glacial rock dust will ensure no lack in trace elements, and bone meal is another cheap addition. Modify your soil however you see fit, but note that organo-chemical culture requires less perlite than most indoor chemical growers use, as the use of lime and worm castings offsetting the harmful effects of soil acidity. Besides, it is much more beneficial for microbial life to have more natural matter in the medium. Once your soil is loaded with organic goodies, beneficial bacteria will enjoy a much more suitable environment. It is also necessary to feed these microbes all along the way by adding natural carbohydrates like molasses in every feed. Molasses is cheap, especially when made from the by-product of sugar beets, and also contain many trace elements. Fish enzymes, seaweed and humic acid are also great additions to most, if not all, waterings. So, we have set the basic groundwork for any successful organic crop. Usually, if you throw in a few other foods, this is the limit of organics. This is restricting for, say, nitrate availability. The N-P-K of organics is released slowly or is limited based on innate natural ratios. (Just as a simple disclaimer, organics can yield great results, but the process is more difficult to achieve and subject to uncertainties, which are not problems calculated chemical formulas have.) This is where chemicals are introduced into the system.

A chemical three-part formula is applied to each watering, although more pure waterings will be required and perhaps a longer flush. With the advent of organic soil, the regular chemical formula can be adjusted to suit the situation (like reducing or completely eliminating nitrogen towards the end of the cycle). Now, you will have much more room to play around with feed ratios because your plants will still have access to a healthy amount of N-P-K in your medium. You also have the chemical arsenal at your disposal if you run into any problems like bug infestations. And the plants will be much more resilient, not just to sprayings, but also to disease and mildew. Organo-chemical growing applies the best of both worlds. Too much sodium nitrate will slowly nullify humus particles (responsible for the uptake of vital nutrients and trace minerals) in the soil. Having a foundation of organic matter in your soil directly combats these effects, including the gradual change in acidity, hostile to beneficial microbial life. This also means that reusing the soil is now a viable option. Organo-chemical culture increases nutrient uptake by equalizing natural ratios in the soil, increases plant vigor, harbors beneficial bacteria, decreases acidity, allows for better water retention and makes available all the required micronutrients and trace elements that could be lacking in a polar chemical method. All in all, itâ&#x20AC;&#x2122;s an easy way to add that extra edge to your system.

“Biosolid” is a public relations term for treated municipal sewage sludge, which is sometimes sold or given to consumers and farms to be used as a nutrient source for gardens and crops. Biosolids contain about 4% nitrogen, and several micronutrients. An estimated 3.5 to 5.4 million dry tons of biosolids are used annually as nutrients for farms and landscapes, and by homeowners. Biosolids are a product of sewage treatment. Waste products enter the sewage system through toilets, drains and other venues, and are collected at sewage facilities known as wastewater treatment plants. Untreated sewage contains everything that has entered the system, not only human waste products, but anything else that gets dumped into the sewer system. Untreated sewage is considered to be a biohazard as it can contain human susceptible pathogens or medical waste. It can also be a chemical hazard depending on the amount of drain cleaners, solvents or other potentially toxic chemicals present. Sewage sludge is defined by the Environmental Protection Agency (EPA) as a solid, semi-solid or liquid residue generated from the treatment of domestic sewage in a treatment works. “Sewage sludge includes scum or solids removed in primary, secondary or advanced wastewater treatment processes and any material derived from sewage sludge,” according to the EPA’s publication “The Standards for the Use or Disposal of Sewage Sludge–Part 503.” It also specifically mentions that material comprised of 99% industrial waste and 1% domestic

waste can still be considered “biosolids” after treatment since it contains some domestic wastewater product. The details of treatment vary, but it generally starts with the removal of large objects that could damage the processing equipment with the use of a bar screen. The waste is then allowed to settle. The portion of the material that sinks to the bottom and is the sewage sludge, and the portion that floats is called scum. The scum is sometimes collected and reintroduced to the

154

Maximum Yield USA | April 2013

collected sewage sludge after the water between the layers has been removed. Much of the water is removed and after filtration and treatment is often released into rivers and oceans. The majority of studies involving sewage treatment effectiveness has centered around this wastewater effluent, and not the leftover sewage sludge. After the sewer sludge has been collected, it is further treated before it can be labeled as biosolids (or, in some instances, the term “compost” is used).

“An estimated 3.5 to 5.4 million dry tons of biosolids are used annually as nutrients for farms and landscapes.” Treatment to convert biosolids into Class A biosolids can be accomplished by aerobic composting, anerobic composting, heat drying or pasteurization. These methods reduce the amount of live pathogens present in the material. Class B biosolids have less stringent requirements, and use is restricted to areas where public access is limited, such as food crop production and grazing lands. Biosolids can be spread on forest sites or placed on agricultural fields as “surface disposal sites.” Cattle and other animals meant for human consumption are allowed to graze on surface disposal sites as long as there is documentation that they will “ensure protection of public health and the environment from any reasonably anticipated adverse effects of certain pollutants that can be present in biosolids,” the EPA says. Class B biosolids can be applied to food crops or grazing land as long as the edible portions do not touch the surface of the soil, and harvest is at least 30 days

after the last application. If the edible portions touch the soil, the last application must have been over 14 months before harvest. Grazing animals cannot be allowed back onto the pasture for 30 days after application. People are also restricted from the site for 30 days on a farm, or one year for general public access. Class A biosoilds are those that have undergone additional composting or drying treatments.

EQ biosolids show lower levels of heavy metals and pathogens, and are exempt from these restrictions. These biosolids can be sold or given away in bulk, mixed with soil amendments and sold to consumers, or bagged for direct consumer use. The United States Geological Survey (USGS) purchased nine offthe-shelf samples of biosolids available to consumers for study. The samples were tested for 87 different pollutant chemicals selected for their ability to pass though current treatments essentially intact. Out of the 87 chemicals tested, 55 were present in at least one of the samples. Every sample had 25 chemicals in common, with one sample having measurable levels of 45. Some of the organic wastewater contaminants (OWCs) they all had in common include an antimicrobial disinfectant, an antihistamine, an antiepileptic drug and steroids.

“The study concluded that biosolids have high concentrations of these emerging contaminants compared to treated liquid wastewater effluent.” These contaminates were found to comprise up to 1,811 ppm in the biosolids tested. The study concluded that biosolids have high concentrations of these emerging contaminants compared to treated liquid wastewater effluent. “What is not known at present is the transport, fate and potential ecological effects of these contaminants once biosolids are applied to agricultural fields, garden plots, and landscaped plants and shrubs,” states the USGS document “Household Chemicals and Drugs Found in Biosolids from Wastewater Treatment Plants.” Another study from the Environmental Science and Technology department of Colorado State University of Pueblo found elevated levels of these types of chemicals found in earthworms taken from areas of repeated biosolid use.

“The thought is that the more bacteria is exposed to antibiotics from sewage products, the more likely a random mutation will result in a resistant form.”

158

Maximum Yield USA | April 2013

One concern of introducing contaminants such as antibiotics into the environment is that they might encourage the development of antibiotic-resistant bacteria. The thought is that the more bacteria is exposed to antibiotics from sewage products, the more likely a random mutation will result in a resistant form. Although the information on long term effects of the use of biosolids is inconclusive at this time, the USGS Toxic Substances Hydrology Program, a of long term intensive land disposal of treated sewage in Cape Cod, has shown the damage caused to nearby an aquifer will take at least decades to return to precontamination conditions. While the question of how best to cope with accumulated sewage sludge is becoming increasingly more important as overpopulation continues, there are ways to deal with it that might prove safer than to store it in our lawns, gardens, and food sources. Alternative uses include using it as a fuel source, in bioreactors or to help restore already damaged landscapes like those left from mining or as a cover material for landfills. One possible cause for concern in the use of treated sewage sludge is the intentional misrepresentation of the product to the consumer. Amendment products that contain biosolids might or might not be labeled clearly as such, and the meaning of the organic-sounding word “biosolid” is not commonly understood by the public. Foods grown under conditions where they are exposed to biosolids, even under direct contact, are not required to bear any indication to allow the consumer to make an informed choice in making purchasing selections.

Maximum Yield recently spoke with Botanicare’s communications manager, Aaron Milldrum, about the company’s origins in the back of an Arizona hydroponics store, the importance of sharing education and how to set up a great growroom. Tell us a little about how Botanicare started. Seventeen years ago, the idea of Botanicare was developed by a small business owner in the back of an Arizona hydroponics store. In 1996, we began selling our first product, Pure Blend Original Organic Compost solution. Pure Blend Original was created to complement existing nutrient lines as a flavor and aroma enhancer. Over years, we have expanded our line to include hydroponic systems, base nutrients, supplements and grow mediums. This expansion and growth would not have been possible had we not stayed true to our values and company philosophy. What are Botanicare’s philosophy and values? As a company, we promote a culture of productivity and creativity, which encourages forward thinking ideas that lead to innovative results and products. We also believe in maintaining close contact with retailers and consumers of our products, which has allowed us to better understand the needs of the industry. This has allowed us to consistently bring the hydroponic industry innovative products.

Botanicare continues to be a leader in the North American hydroponic industry, and we are committed to our core values that emphasize relationships, innovation, integrity and environmental and social responsibility. These core values embody our philosophy and have helped the company build a strong foundation to support its continued success while staying true to our roots. Which was the first product you created? Pure Blend Original is where it all started. Customers were looking for a way to increase flavors, aromas and overall quality. Pure Blend Original was developed to provide growers with a tool to consistently harvest the best-quality fruits and flowers. Pure Blend Original was the genesis of the well-known, “Botanicare quality.” In fact, staying true to our core value of innovation, this premier organic flavor and aroma enhancer just got better than ever. Pure Blend Tea (formerly Pure Blend Original) combines the key elements of both Pure Blend Original Grow and Bloom into one highly effective formula. Pure Blend Tea has the perfect balance of premium natural and organic ingredients fortified with ultra-soluble humates, organic plant acids, trace minerals, vitamins and select amino acids. Pure Blend Tea is still brewed in small batches, maintaining strict quality control, and still contains all of the major components that are essential to a significant increase in end quality.

What is your most popular selling product today? Why do you think that is? Cal-Mag Plus is the number one selling bottle for many retailers. It’s a great example of how maintaining a close relationship with our end-users enabled us to develop this popular product. As plant genetics improved, and the use of RO water and coco-based media increased, Botanicare recognized that growers were lacking a calcium and magnesium supplement. Some companies have tried to duplicate the Cal-Mag formula, but it remains the leader because growers trust the proven quality and consistency of Botanicare’s products.

“ we promote a culture of productivity and creativity, which encourages forward thinking ideas that lead to innovative results and products.” You offer a lot of information on your website: Hydro 101, growroom layouts and nutrient calculators. Why do you think providing education to your customers is important? Hydroponic gardening is often a challenging hobby or profession, especially when deciding where to start. We believe providing our customers with a strong foundation is critical to their success and the success of the industry. These tools help inspire and empower growers with the information they need to have a healthy and lucrative harvest.

system using Botanicare® Low Tide Trays. Coco coir is an ideal grow media because it is ecologically sustainable, easy to work with and increases growth rates. Although many people attempt to build their own drain trays using a variety of materials, the time saved using a plastic tray with an optimized drainage pattern has many advantages. The drainage grid helps remove excess water quickly, which combats humidity and decreases the chance of algae, mold and other pathogens from taking hold in standing water. Grow trays are also easy to clean, reconfigure and move from one growroom to the next. All Botanicare Trays are made of premium ABS plastic and are designed to last a lifetime. How important do you think sustainability is to the indoor gardening industry as a whole? How do you incorporate environmental practices into your company? Botanicare integrates sustainable and environmentally responsible measures into all facets of its business. Botanicare’s new thermoforming facility is one of Arizona’s largest private sector solar projects. Our facility currently has over 24,000 sq. ft. of solar paneling. Over the next 25 years, the use of these solar panels will prevent over 7 tn. of carbon dioxide emissions from entering the earth’s atmosphere. This equates to 170,000 trees being planted or eliminating the emissions of over 1,200 cars. Another way we stay environmentally responsible is by only selling coco-coir-based products. We are proud to offer a Cocogro plugs, a new cloning plug that is completely peat free! Why? Peat harvesting is not sustainable. The microbial life contained in peat bogs is complex and stores mass amounts of carbon dioxide that would otherwise be released into the atmosphere.

Also, if I was a beginner looking to set up a growroom, which layout and products would you suggest for me? The first thing I always tell people is to set up a growroom that is manageable in both size and required resources. Growers often make the mistake of taking on more garden than they have the resources for. A fully optimized 2,000-W set-up can outperform a 4,000-W garden that is constantly battling temperature fluctuations, humidity issues and poor air circulation.

Amid the 4,000-sq.ft. facility is an interactive grow room showcasing several of his custom-built units. There is no better way to discover and explore the world of hydroponics. “There’s a lot of love in this room,” Daniel says. “It’s a handson way for customers to see how and why our products work.” The growroom is a big draw not only for beginners, but experienced gardeners as well. Whatever the crop of choice—from peppers to orchids and everything in between— Maximum Grow can design and build the perfect hydro system.

While his first days in business were hard, Justin prevailed by hitting the streets, volunteering at local community gardens and schools and sharing his knowledge and enthusiasm with everyone he met. “My ultimate goal is to inspire the younger generation to understand the importance of gardening,” he says. It didn’t take long for word of mouth to kick in, and the rest is history. “It’s not work,” Justin says. “I get to enjoy my passion everyday and share it with my clients.” With a pristine operation, infectious enthusiasm and insistence on the best, Justin will no doubt achieve his many goals through Maximum Grow. The company is currently expanding its current location by 2,000 sq.ft. and plans to open a second location in fall 2013.

DO YOU KNOW?

Light deprivation is a technique that cuts out sunlight from your greenhouse when you require extra hours of darkness to flower your plants. It gives a gardener the ability to step into the same game as an indoor grower while receiving all the benefits of greenhouse growing. The most commons factors that affect seed germination are moisture, salinity and heat. Contrary to popular belief, sunlight is not a standard factor that influences seed germination. In fact, sunlight can do more harm than good as it can overheat the seeds and seedlings and kill them. Always double check the package instructions.

Toxins from pesticides and chemical fertilizers can find their way into the grower’s living space. Unsuspecting gardeners might touch a wall or piece of equipment in their gardens not realizing the residual insecticide they sprayed just a few days prior is still active. Always use caution!

Some woods contain tannins, which are toxic to plants, and therefore need to be composted for lengthier periods of time if they are to be used in your garden. For freshly gathered pinebark, wood chips or course sawdust, composting for at least a year under warm climatic conditions is recommended.

When a traditional red tomato is changing from the orange to red color, the acidity drops, which increases the fruit’s pH. This has important ramifications to harvesting as tomatoes that are fully vine ripened can have a reduced blend of acid to sugar.

Foods grown under conditions where they are exposed to biosolids (treated sewage waste) are not required to bear any indication to allow the consumer to make an informed choice in making purchasing selections.

Sodium-chloride softened water should never be given to your plants, especially in a hydroponic garden, as plants are very sensitive to levels of sodium.

Deciding the intensity of artificial light you give your seedlings and transplants will often have more to do with temperature, as they are sealed up tight underneath a humidity dome. This is because seedlings or cuttings can get dehydrated in environments that are too warm.

10 facts on... iron by Philip mcintosh

Iron, atomic symbol Fe and atomic number 26, is a brittle, silvery gray metal of great biological and economic importance. Like many other transition metals, it has a number of different oxidation states but the +2 and +3 ions are of greatest biological importance. Most plants will be okay if the iron concentration in their dried matter is about 50 ppm; however, some plants accumulate concentrations of many times that without ill effect. Chlorophyll is green. This explains why plants that are deficient in iron lose their green color, since they canâ&#x20AC;&#x2122;t make enough chlorophyll. Iron deficiency symptoms are not always so clear-cut though, and can be mistaken for deficiencies of sulfur, manganese or zinc.

Why does it have the symbol Fe? It is one of the oldest known metals and was called ferrum by the ancient Romans.

Iron plays a role in many energy transfer reactions in plants because it can readily be made to switch back and forth between the +2 and +3 oxidations states by adding or removing an electron. Iron is required for the synthesis of the complex molecule chlorophyll, which is critical in the process of photosynthesis. Iron is not very soluble at neutral pH, which is why it is almost always provided chelated with ethylenediaminetetraacetic acid (EDTA), diethylene triamine pentaacetic acid (DTPA) or other chelating agents. Chelators wrap around the iron to keep it protected from other ions so it stays dissolved and does not precipitate out of the nutrient.

The concentration of iron in nutrient solutions is sufficient at about 2 to 3 ppm. Since the concentration of iron in water supplies varies, it is a good idea to test for it before designing a nutrient formulation for a particular application.
