Thank you! Amanda Hair

Thank you so much for this. I’m pretty shocked that I won, but I’m also super stoked. I’ll be sure to document my use of the pots in a subsection of my blog and give feedback on how they work for me. Michael McGowan

Commenting on Compost

The Greenhouse (Maximum Yield USA, May 2012) and Water (Maximum Yield USA, June 2012) issues had a lot of pertinent subjects. I especially enjoyed the article on biodynamic compost. I think it would be great if you could fill people in a little more in a future issue on how to make their own. Can you [also] publish an article on essential microbes? [It’s] a subject I’ve just heard of from a knowledgeable person working at one of the indoor gardening stores in your directory. When I asked for Alaskan humus, wanting compost that was supercharged with microbes and many beneficial stains of fungus like mycorrhizae, he told me to look into essential microbes, populations of microorganisms and beneficial bacteria you can harvest, colonize and breed yourself. Thanks for increasing awareness in diverse issues pertaining to this beautiful art and science of growing plants in progressive ways. Sincerely, Oskar Newsman, A.K.A. G.I. Grow Stay tuned for upcoming issues of Maximum Yield, particularly our December All About Organics issue, which will highlight many of your requests and, hopefully, answer these questions and more.

“As humans, we tend to consider ourselves the most central entity in the universe. It’s called anthropocentrism and it is rampant in modern society. We think we have the world under our thumbs, and we have screwed it up in the process. Take artificial fertilizers, nuclear bombs, water fluoridation, table salt, clear-cutting virgin forests for paper, pharmaceuticals and processed foods. On every level we have removed the magic and replaced it with materialism.” Evan Folds, Maximum Yield USA, May 2010 Evan, I couldn’t agree with you more. It’s like your right inside my head. I totally support this type of analytical and responsible thinking toward our modern world. I think a good way to start fixing our mistakes is by first acknowledging them as a community, then making baby steps to change our views and actions toward sustainability, healthy living and the value of life on Earth and its delicate biological systems. Matt Stergiou

We’ve Got You Covered

Great magazine this month. I hate to judge a book by its cover, but I knew from the cover I would enjoy it, and sure enough I am. Keep up the good work helping people get their maximum yield. Davy Stanford

Nuts About Nutes

Loving the new issue this month! The focus on the nutrients was especially awesome. North Country Hydroponics

From Stressed Out to Easy Street

Because of your magazine, I was able to pinpoint the problem of my garden. It was in bad shape for a couple weeks. Turns out heat stress caused by 98° weather and no airflow, plus a small case of chlorosis, is bad combo. I’m a first-time gardener; after about three years, [I became] seriously fed up with in-ground garden maintenance, weeding and such. It was too big of an area to maintain by myself, so I started a grow box. It’s much easier, I must say, as far as maintenance goes. I just want to say thank you for the education and I hope to [attend] your next garden trade show. Juan Martinez







ASK THE EXPERTS I'm growing tomatoes in a 430,000 sq. ft. greenhouse. I'm looking for information about bioponics, i.e., using natural fertilizer with my fertigation system. Arno Natural and organic fertilizers can be used in hydroponics. However, the process is highly technical and comes with a few challenges. Firstly, obtaining Dr. Lynette Morgan high-quality, concentrated, natural fertilizers for commercial production is much more costly than using chemical fertilizer salts. Secondly, growers usually have to blend many different sources to get the balance of minerals just right for heavy-feeding crops like tomatoes, and often nutrient deficiencies can become a problem. Because natural fertilizers are often unprocessed, the system relies on strong microbe populations in the growing media and root zone to carry out mineralization of the organic nutrients to release plant-usable nutrient ions. This process can strip oxygen from a plant’s root zone under warm growing conditions. Also, natural fertilizers are

carbon-based, and as such, can ferment or go bad quickly, and they tend to block drippers and emitters. There are, however, a few good natural nutrient products on the market for hydroponic use that have been wellprocessed and mineralized and suit media-based growing systems (coconut fiber is a good substrate when using natural fertilizers and in organic systems). I advise trialing a number of these to determine which products help your crops grow best in your system. Kind Regards, Dr. Lynette Morgan

Can you use Epsom salts as a magnesium sulfate treatment for plants? Juan Martinez

Eric Hopper

22

Yes, Epsom salt can be used as a magnesium sulfate treatment for your plants. Epsom salt is a form of magnesium sulfate that is highly soluble in water. This means it can be easily fed to your plants by foliar or root applications. Besides being highly soluble in water, Epsom salt also has a relatively neutral pH compared to other magnesium sources, which makes it compatible with horticultural applications. For foliar applications, start with 1 tbsp. per gallon. of water. For root applications, use 2 tbsp. per gallon of water. Allow the Epsom salt to dissolve before feeding the concoction to your plants. For plants showing signs of a magnesium deficiency, it is recommended to use a foliar application because plants can absorb nutrients more quickly through their leaves than their roots.

Eating Citrus Fruit Could Lower Women's Stroke Risk New research found that women who ate high amounts of flavanones in citrus, especially oranges and grapefruit, had a 19% lower risk of blood clot-related (ischemic) stroke than women who consumed lower amounts. More studies are needed to confirm the association between flavanone consumption and stroke risk, and to gain a better understanding about why the association occurs, the authors said.

Why Store-bought Tomatoes Taste Like Cardboard The mischievous culprit of why tomatoes taste like cardboard is a gene mutation discovered accidentally around 70 years ago, which is now deliberately bred into nearly all modern tomatoes. This mutation makes tomatoes a uniform and seductive deep scarlet red when ripe, but it also deactivates an important gene responsible for producing the sugar and aromas that are essential for a fragrant and flavorful tomato. When researchers “turned on” the deactivated gene, the fruit had 20% more sugar and 20 to 30% more carotenoids when ripe. (Source: treehugger.com)

hydroponic news, tips and trivia

Can Organic Food Feed the World? A new study published in Nature concludes that crop yields from organic farming are generally lower than from conventional agriculture. That is particularly true for cereals, which are staples of the human diet, yet the yield gap is much less significant for certain crops and under certain growing conditions, according to the researchers at McGill University and the University of Minnesota. “To achieve sustainable food security we will likely need many different techniques—including organic, conventional and possible hybrid systems—to produce more food at affordable prices, ensure livelihoods to farmers and reduce the environmental costs of agriculture,” the researchers conclude. (Source: sciencedaily.com)

A Greener Way to Raise Cotton and Combat Nematodes USDA scientists are using molecular tools to help cotton growers cut back on their use of pesticides against the root-knot nematode. They are hunting for genetic markers that will lead to development of commercial varieties of cotton better equipped to resist the pest. (Source: ars.usda.gov)

Keep That Racket Down! A growing body of research shows that birds and other animals change their behavior in response to human-made noise, such as the din of traffic or the hum of machinery. Then, since many animals also pollinate plants or eat or disperse their seeds, human noise can have ripple effects on plants too. To find out what animal responses to noise might mean for plants, the researchers conducted a series of experiments in northwestern New Mexico. The experiments revealed that noise might be bad news for many plants, but it could indirectly benefit others (the black-chinned hummingbird made five times more visits to plants in noisy sites than quiet ones because its predators were driven away).

Add Heat, Get Flavor A spell of hot, dry weather in the Midwest this July had an interesting effect on chili peppers. Instead of being mild, as they usually are at that time of year, the chili peppers were blazing hot. The increased intensity was the result of a higher concentration of alkaloids, the substance that binds to heat resistors on the tongue, due to the hot, dry weather. Also, the absence of water ensures that the flavor was not diluted, which also helped to make for a stronger taste. The same thing happens with onions, garlic and certain fruits too. Local farmers said they noticed a taste difference in several of their crops. Melons were also reputed to be extra sweet this year as a result of the weather. (Source: freshplaza.com)

Glass Ideal Alternative to Perlite, Parboiled Rice Hulls A recent study compared perlite and parboiled rice hulls—two common components used to increase air-filled pore space (AFP) in substrates—to a new aggregate produced from finely-ground waste glass. The experiments showed that new aggregate resulted in a higher AFP and a higher water-holding capacity than equivalent perlite-containing substrates. As such, it was concluded that the new aggregate could be used as an alternative to adjust the physical properties of peat-based substrates. (Source: sciencedaily.com)

Tiny Plants Could Gut Costs, Shrink Environmental Footprint Burkhard Schulz, a Purdue University assistant professor of plant biochemical and molecular genetics, has found a way to knock out the steroid function in corn plants. Inhibiting steroids in maize produced short, feminized versions of the plants that developed more kernels where pollen would normally grow. The process uses propiconazole—a chemical used to treat fungal dollar spot disease on golf courses—which costs about 10¢ per gram. It is speculated that these shorter plants could reduce agriculture’s environmental footprint as they would need much less water, fertilizer and pesticides. (Source: sciencedaily.com)

Introducing the Humboldt MicroMole Electronic Ballast Lumens are for humans; for plants, it’s all about the micromole. The standard measurements of light output have traditionally been done in foot-candles, lumens or lux. They only quantify how humans experience the brightness of light. Plants, however, use a much wider spectrum of colors for photosynthesis called PAR spectrum (photosynthetically active radiation). Photosynthesis is not driven by the brightness of light, but purely by the number of photons hitting your favorite crops. This is measured in micromoles. Research and development for the Humboldt MicroMole electronic ballast was done to maximize PAR light. With dimmable features, the SuperMole setting will send your micromole reading and yields off the charts. The MicroMole is competitive in both pricing and performance.

Anyone who has grown plants in a greenhouse is well aware of the challenges associated with how air is moved into and within the greenhouse structure. Most greenhouses are designed for a specific use so that the spacing and placement of exhaust fans and cooling pads, as well as interior mixing fans, are placed to make atmospheric control within the greenhouse as effective as possible. Unfortunately, even with the best of designs, growers can be constantly struggling to establish and keep the interior of the greenhouse conforming to the requirements of the plants being grown. With most current greenhouse designs, it is not an easy task to maintain certain parameters within the greenhouse—as well as the plant canopy—when growing tomatoes. In some greenhouses, I have seen large fans mounted in the greenhouse gable area to push air toward the plants with the hope that there is sufficient force to penetrate and mix the air within the canopy. In most common greenhouse designs, a cooling pad is mounted at one end of the greenhouse and an exhaust fan at the opposite end, usually 4 to 6 ft. off the

Air is pulled through the cooling pad by the operating exhaust fans, and the cooled air is pulled solely through the top half of the tomato plants, leaving much of the air within the rest of the canopy undisturbed. However, my best tomato yields were obtained in a polyethylene-covered, 30-ft.-wide greenhouse fitted with a cross-flow ventilation system with the exhaust fans and cooling pads mounted at floor level. This way the airflow was being directed through the plant canopy at the base of the plants. Having moving air within the plant canopy has several significant advantages: it has a cooling effect, it keeps the plant foliage dry and the carbon dioxide concentration within the canopy air at the ambient level, and it stimulates the evaporation of transpiring water from leaf surfaces.

Curing the Flaw

Maintaining upward movement of water in the transpiration stream within the plant reduces the potential for nutrient element deficiencies—for example, such water movement within the plant can reduce the potential for the occurrence of blossomend rot in setting and developing fruit. Keep in mind, however, that ventilation—important as it is—has its flaws. Drawing air into the greenhouse invites the potential for insect invasion; therefore all openings must be properly screened. However, depending on the mesh size of the screen, airflow can be restricted. Also, ventilating the greenhouse will remove any extra carbon dioxide that has been generated to enhance photosynthesis—this is a significant, expensive loss that can reduce the effectiveness of the added carbon dioxide on plant growth. Most greenhouses in use today have these design faults. In order to correct some of these inadequacies, some growers place plastic pipes or tubes at the base of each tomato plant row. This solves the canopy air mixing problem, but other insufficiencies remain. For example, the air being drawn into the greenhouse might not be sufficient to obtain the desired

The ideal ventilation system conditions air in its own facility before introducing it into the greenhouse through floor vents. The return air is then taken from the greenhouse gable area to be processed through the air-handling facility before introducing it once again to the greenhouse. With such a recirculating system, the air properties can be more easily maintained at the desired temperature, relative humidity and carbon dioxide content. The only required opening into the greenhouse would be a double door entrance for workers; therefore, there are no other openings that can provide the entrance of pests and unconditioned air into the greenhouse. I visited an experimentally designed greenhouse where air was being conditioned in a separate facility and then introduced into the greenhouse through holed tubes running along the base of the tomato rows. The return air was drawn from the greenhouse gable and taken back into the air handling facility for reconditioning.

Keeping Things Cool Through Evaporation

Heat and humidity: plants need certain levels of these for optimum growth, but too much of them means plants get roasted or steamed in an overly hot environment. Then, if these conditions are combined with a lack of airflow and cause plants to stagnate, physiological disorders become common place and fatalities can occur. A good rate of fresh airflow can rejuvenate suffocating crops, but heat can still be an issue if it’s stiflingly hot and dry outside—in this case, the air vented into the growroom has little cooling effect. Luckily, indoor and greenhouse growers have long known how to take advantage of what is termed the “latent heat of evaporation,” meaning that combining water with sufficient airflow can give some fairly impressive cooling, provided that a few other conditions are met. Calculating just how much ventilation and evaporation are required to sufficiently cool down a small growing area for maximum growth does require some number crunching; however, once the basics are understood, this process is not as difficult as many growers think.

Evaporative cooling walls make use of air movement and water to cool the growing environment.

Ventilation and cooling methods

The simplest way of using ventilation to cool a growing area is to bring in fresh, cooler air from outside while venting out the stale, moist and warmer air at the correct rate. Using ventilation

64

Maximum Yield USA | October 2012



Keeping Things Cool Through Evaporation this way can reduce the inside temperature to about that of the outside air; however, the rate at which air must be exchanged can be surprisingly high, particularly in small, enclosed spaces where unvented high-intensity lights can be adding to the heat load. In warm climate greenhouses with mature crops, the rate of ventilation required to simply remove the heat from incoming solar radiation, supply fresh CO2 for photosynthesis and lower humidity from crop transpiration is often as high as one complete air exchange per minute. Still, a high rate of ventilation might not be enough in warm climates. If the outside air is already super heated on a hot summer’s day, the incoming air can seem like a blast from the furnace rather than a cooling breeze. Further cooling methods need to be incorporated into the ventilation system in this situation, and one of the most effective and commonly used is evaporative cooling. Ventilation requires air to be pulled in from the outside for cooling, providing fresh supplies of CO2 and humidity control.

66

Maximum Yield USA | October 2012



Keeping Things Cool Through Evaporation How evaporative cooling works

As water evaporates into the air, energy is lost and causes the air temperature to fall—this is the same as the cooling we feel when wet skin is exposed to moving air. In a growing area, this evaporation of water for cooling can take advantage of plants’ requirements for fresh air. The latent heat of evapo-

Warm, humid air is required to help control a number of fungal and bacterial pathogens.

ration of water is 970 BTU/lb.; meaning that 970 BTU of energy is removed from the environment for each pound of water that is evaporated. Ventilation is an essential component of evaporative cooling as the evaporation of water causes humidity levels to rise. Since high levels of humidity can create problems for plant growth by slowing transpiration and increasing the occurrence of disease, this humid air needs to be vented out at a sufficient rate to keep relative humidity below 85 to 89%. Air pulled into a greenhouse or indoor garden can be cooled by fan and pad cooling systems, which usually consist of exhaust fans at one end of the indoor garden or greenhouse pulling air in through vents on the opposite side. The vents contain porous pads that have water circulating over them. Water evaporates as air is pulled through the wetted pads, thus removing energy from the air and lowering the temperature in the process. The cooled air is then circulated through and over the

68

Maximum Yield USA | October 2012


crop, cooling the growing environment, and vented out the other side. For fan and pad cooling to work at maximum efficiency, it is important to keep the growing area as air-tight as possible. This way the air being drawn in from outside is forced over the wet pads and does not come in through other openings where it won’t be cooled. Also, greenhouses should have air-inlet vents positioned to take maximum advantage of prevailing winds. This way, the system takes advantage of natural airflow rather than working against them. Some hobby growers make their own fan and pad system using capillary matting and other similar materials; however, pads can rot over time if they are continually in use and, therefore, wet for most of the day. Commercially designed evaporative cooling pads are manufactured from material that might incorporate wetting agents and other compounds to resist rot. An algaecide might also be used in the water to prevent the buildup of algae on surfaces, which lowers the efficiency of the cooling pad.

HID lamps can be a large contributor to heat buildup in small, confined growing areas, increasing the requirement for rapid ventilation rates.

Keeping Things Cool Through Evaporation

Another method of evaporative cooling is using misters or high-pressure fog systems. These are more suited to larger greenhouse environments where uniform cooling of a wider area is required. Fog or mist systems use nozzles to form fine water droplets under high pressure. Fog contains droplets of 0.05 to 50 microns, whereas mist is larger droplets of 50 to100 microns with the smaller droplets absorbing heat from the environment faster as they vaporize. Fog is a better option for most situations, as it tends to fully evaporate before any droplets can fall on the plants below—wet plant surfaces encourage the development of many fungal and bacterial pathogens and should be avoided with any evaporative cooling system in use. Just as with fan and pad cooling, it is vital with fog and mist systems that there is sufficient air ventilation and movement to both circulate the cooled air and draw it out once humidity levels increase. A disadvantage with fog or misting cooling, however, can be blockages of the high-pressure nozzles; so, in some cases, the water supply could need ultra-fine filtration to prevent this occurring.

Fogging is an efficient way of cooling the growing environment.

Air temperature and humidity

The amount of cooling that can be achieved with evaporative methods is not unlimited. It is linked to temperature and humidity of the incoming air. To work out how much cooling is possible in a wellventilated growing area, two variables are important: dry-bulb and wet-bulb temperatures. The normal air temperature that we measure with a standard

70

Maximum Yield USA | October 2012


thermometer placed in the ventilation stream of the growing area is the dry-bulb temperature. The wetbulb temperature is a little more complex. It is the lowest temperature that can be achieved by evaporation of water only, and it is linked to the moisture content or humidity of the incoming air. In fact, the wet-bulb temperature tells us how much cooling is possible given the temperature of the incoming air and its relative humidity level. The higher the relative humidity of the air, the lower the amount of evaporation can occur; thus, less cooling is possible. Wet-bulb temperatures can be easily measured onsite with use of certain electronic humidity meters. Growers who don’t have meters with the ability to measure wet-bulb temperatures can still work out the cooling potential of evaporation by the slightly more old fashioned way of using psychometric charts. These charts allow wet-bulb temperature to be calculated based on dry-bulb or normal air temperature and the relative humidity, which can be measured with a standard RH meter placed in the air stream. The best time to measure or calculate wet-bulb temperature is midafternoon when the outside air, which is to be vented into the growing area, is at its warmest. This should give the greatest difference between wetand dry-bulb temperatures and thus the maximum cooling effect of evaporation can be determined. As a general rule, the air in the growing area or greenhouse can be cooled and held at wet-bulb temperature plus 3°F. When evaluating how much cooling can be achieved with current temperature and humidity levels, it's also important to remember that the cooled air will gather heat as it circulates in the growing area and is eventually vented out. Heat accumulation will depend on factors like how far the cooled air travels inside the growing area, heat output of lamps and solar radiation from direct sunlight. It is possible for the temperature buildup inside the indoor garden or greenhouse to reheat the circulating air to greater than that of the outside environment, so correct calculations of both the amount of evaporative cooling and amount of air to be vented in and out need to be carried out correctly.

The following equation can be used to work out how much water needs to be evaporated into a known area and how much air movement or ventilation is required in order to reduce the temperature inside a growing structure to the required levels. Note that most of the equation is calculated using metric figures, but the end result is imperial. Equation for fog cooling of greenhouses Step 1:

enrichment also allows stems and branches to grow faster, often causing tremendous growth in plants during the vegetative stage." The indoor garden is a chain of networks much like the human body. If one element of that system fails or is not working at the required level, then the whole chain becomes weakened and the system can collapse. You can have as many high-quality HID light bulbs running in a room, but if the nutrient levels are too low, it will make no difference. You can use the best nutrients that money can buy, but you will just be flushing money down the drain if the pH levels are not in the ideal 5.8 to 6.5 range. The same applies to CO2-enrichment systems—if you are not ventilating the room, expelling stale air, bringing in fresh air and keeping the temperature and CO2 at a plant-friendly level, you might actually be doing your plants more harm than good. This article aims to highlight and tackle the symbiotic relationship between CO2 generators and ventilation, and how they cannot truly benefit your plants in the desired way without working together in harmony.

What can CO2 do for you?

CO2 is used by plants in photosynthesis, the process through which the plant converts energy from the sun, water and CO2 into sugars and O2. The air around us contains roughly 200 to 300 ppm (or, 0.02 to 0.03%) CO2. Plants do well in this range, but we have learned that you can supercharge your garden by enriching the 80

atmosphere in your grow room to 1,200 to 1,500 ppm (or, 0.12 to 0.15%)—however, keep in mind that anything above this can be harmful to plants and humans. When every aspect of the garden system is aligned, this CO2 enrichment has been known to double, even triple, yields. CO2 enrichment also allows stems and branches to grow faster, often causing tremendous growth in plants during the vegetative stage. This can actually take weeks off the amount of time you would need to grow your plants before they were large enough to switch to the flowering stage. This saves you time, as well as money. You can also get more crop rotations in each year, saving you money on electricity. If you are using HID bulbs in your garden, the number of lumens and PAR watts drops off over time; however, CO2 enrichment allows you to efficiently utilize the bulbs in your growroom and get the most out of them. You might get one more crop rotation per bulb when adding CO2 to your garden than without, and that’s just money back in your pocket. Another benefit of enriching your growing atmosphere with CO2 is that plants in this environment can handle growing at higher temperatures. In fact, they prefer it. The ideal temperature for plants in a CO2-enriched 82

(Keep in mind, however, that fluorescent light bulbs should not be used if you’re enriching the atmosphere of your growroom with C02. Fast growing plants require intense light to produce large yields and CO2 enrichment will only enhance the plant’s ability to absorb and assimilate PAR.) With the temperature in the room higher, metabolic rates within the plant will accelerate and growth will increase. This also means that you can run ventilation fans less. In summer months, you won’t need to run your air conditioning as high or as frequently. This can mean some big savings on your electricity bill.

Generating CO2

There are many ways of generating CO2. Some ways are easier and more reliable than others, but each can be effective. Fermentation and decomposition, like the processes used to make wine or organic compost, can be utilized to produce CO2. However, one issue with these methods is that it’s impossible to control that amount of CO2 being made— it can vary depending on certain factors, such as room temperature. Also, there is the problem of the potential odors produced by having organics decomposing in your growroom. These would attract pests. 84

Using dry ice is another way to enrich your growroom’s atmosphere with CO2. Dry ice is frozen CO2 that turns from a solid to gas when it comes into contact with the atmosphere, without ever becoming a liquid. The downside to using dry ice is that it is difficult to store enough of it to replenish larger growrooms. Dry ice is only practical in the smallest growrooms, and even then it can be expensive. A CO2 emitter is a practical and cost-effective way of enriching a small, single-light room with CO2. A CO2 emitter system uses tanks of compressed CO2 and pumps it through tubing throughout your room using regulators and valves. Since CO2 is heavier than air, it is most effective when the tubing is placed along the ceiling of your room above the plants. This will allow the CO2 to fall among the foliage where it can be used by the plants. Also, CO2 emitter tanks can be refilled at most hydroponics retailers at an affordable cost. CO2 generator systems are the most practical for largerscale or commercial growrooms with multiple lights. This system involves creating CO2 by burning fossil fuels, usually natural gas or liquid propane (other fuels might not be safe and can emit poisonous gas as a byproduct).

There are a number of reasons we need to ventilate our growrooms. If the temperature becomes too high, we need to remove the heat from the room. When there is an excess of humidity, it must be vented from the growroom to prevent things like powdery mildew from inflicting our plants. Ventilation is also needed when CO2 levels are toxic or too low. When enriching the atmosphere of your growroom with CO2, the trick is to manage all these things while keeping the CO2 in the air long enough for it to be of some benefit to your plants. With CO2 being heavier than air, you must also consider circulating it throughout the growroom. A couple well-placed oscillating fans positioned near where the CO2 is being released can do a fantastic job of circulating the CO2 and keeping it off of the floor. As mentioned above, there really is no way of regulating how much CO2 is being produced when generating CO2 via fermentation, decomposition or dry ice. You only have control of how much is allowed to stay in the room. There are some very high-tech devices that can be used to measure CO2 levels. You can hook your fans up to a CO2 monitor specifically designed for growing and have it set to vent your room once the CO2 levels reach a stage that could

be harmful for plants or humans. Alternatively, you can set up the exhaust fans to a thermostat that will vent your growroom once the room reaches a certain temperature deemed to be too high for the plants to thrive. If you are using a CO2 generator or CO2-emitter system, you can have more control. There are some great interfacing products that can totally monitor and control the levels of CO2 being generated in the room, as well as monitoring the humidity and room temperature. They can shut off fans when CO2 is being generated, shut off CO2 generators when they hit the ideal level and then turn on fans when the room becomes excessively humid or too hot for the plants. These products can be expensive, but they offer the gardener total control of these elements and you really can’t put a price tag on that. Garden systems are only as strong as their weakest link. CO2 enrichment is no different. If you are not using your exhaust fans properly, providing the right types and levels of nutrients, using the right spectrum and strength of lights, you will be wasting your time by enriching your growroom atmosphere with CO2. However, having all these factors dialed in and enriching your grow space with CO2 can lead to tremendous growth and yields. When gardening with CO2, the sky’s the limit. 90

10 facts On…ventilation by Philip mcintosh

1. The word ventilation comes from the Latin word ventilationem, meaning “an exposing to the air.” 2. The original use of the term ventilate was in relation to tossing grain in the air to remove chaff. 3. The first use of the term ventilate to mean “provide fresh air to a room” is believed to have occurred in the 1660s. 4. A Google search for ventilation fan returns 4.5 million pages. 5. Ventilation fans provide no direct cooling. The impeller of a fan actually imperceptibly warms the air as it passes through the fan. 6. Fans can be coupled with wetted cooling pads, which can lower the temperature of the air moved by the fan. 7. Ventilation (exchanging the air in a room) is not the same as recirculation (moving the air in a room without exchanging it). 8. Recirculation systems can be generally classified as parallel or series. 9. A parallel recirculation system uses fans that are next to each other, such as along a wall, to move a mass of air across a room. 10. Series recirculation is characterized by fans arranged in such a way that the output of one fan is directed toward the input of another.

While many of you are familiar with the concept of aquaponics, as well as several basic components of aquaculture and hydroponics, there is some other information you need before you give freshwater aquaponics a try... In 2009, total world aquaculture production of fish was still significantly lower behind wild-caught production (55.1 and 90 millions tons, respectively). However, aquaculture remains the fastest growing sector in agriculture, with an annual average increase of 6.6% from 1970 to 2008. The potential for profit102

able food production of fish and plants has never been more prominent. After all, aquaculture must supply a growing population and there is an open, global market to generate revenue. Also, there is need for growth and development of additional aquaculture and aquaponic facilities to meet domestic needs.

So, growing fish through aquaponics sounds pretty good, doesn’t it? Well, let me break it to you quickly: not all fish are the same and not all are as easily cultured. So, even though you don’t need to have an advanced degree in aquaculture or prior experience, I still recommend starting simple.



The Aquaculture Component to Aquaponics

This recirculating NFT aquaponics system is made from 3 in. PVC with non-toxic glue.

A first point to ponder is if your fish species of interest takes pelleted food easily. If not, you will have great plant production, but no fish to sell and lots of wasted feed. Personal experience has shown that yellow perch and striped bass and their hybrids are prone to stress and subsequent disease outbreaks. Freshwater prawns are certainly catching steam domestically, but they are best left to pond production as cannibalism is quite high! Popular salmonids (trout and salmon) require pristine-waterquality parameters. For example, they need above 8 ppm of dissolved oxygen, which is only accomplished with colder water temperatures or injection of pure oxygen—an endeavor that is pricey and potentially dangerous to your aquatic friends. Therefore, it is recommended to try black/white crappie (Pomoxis nigromaculatus and Pomoxis annularis), bluegill and relatives (Lepomis spp.), largemouth bass (Micropterus salmoniodes) and tilapia (Oreochromis spp.). In regards to fast growth, high-stress threshold and ease of accessibility, tilapia is arguably the best choice. Fish meal comprises the bulk of protein in most fish diets. This feedstuff is predominately harvested from marine fish like menhaden. The harvest of these fish domestically has been capped, thus creating an exponential growth in price. Therefore, for aquaculture to be sustainable, fish meal cannot comprise the largest component of diets. Instead, alternative plant-based protein sources have been tested and utilized. Due to domestic supplies, soybean meal is one of the better sources of protein suitable in 104

aquatic diets, but is not without problems (refer to anti-nutritional factors in soybeans for more information). Tilapia is considered an omnivore and is very tolerant to a high-inclusion rate of soybean meal in pelleted diets. Though proteins, carbohydrates and lipids are integral to fish production, it is the mineral premix found in fish diets that is most important to plants. This mineral premix will contain most of the macro- and micronutrients needed for plant growth and development. However, be aware that fish will utilize a large component of the nutritional value of the pellets; as such, overfeeding will be integral for aquaponic systems to ensure there are no plant-nutrient deficiencies. Proper water-quality parameters are also paramount to fish and plant health. Ammonia is a waste product that is excreted via the gills, urine and feces of fish. However, ammonia at a specific dose is detrimental to fish and plants. To forgo frequent and inefficient water changes,

be sure to promote denitrifying and beneficial bacteria. Nitrosomonas spp. and Nitrobacter spp. in turn will convert ammonia to nitrite and then to nitrate. It is this final form that is relatively non-toxic to fish and that can be directly utilized by plant roots. For “seeding” the water, you can add fish waste via a low-density stocking of fish. Or, for fishless seeding, target a dosing rate of at least 1 ppm ammonia directly. This will promote colonization by Nitrosomonas spp. bacteria. As the ammonia levels drop and nitrites increase, subsequent Nitrobacter spp. bacteria colonization will occur. A critical component to keeping both types of bacteria healthy is having sufficient access to their food sources at all times. Therefore, if you 108

Maximum Yield USA | October 2012

are doing a fishless seeding, make sure you do not allow ammonia levels to reach zero, as this will eventually lead to a crash in the Nitrosomonas spp. population, negating the whole process. Also, do not add fish to pre-seeded water if the levels of ammonia are 1 ppm or above. Both fish and plant roots alike are net consumers of dissolved oxygen. If values are too low, both will suffer from stunted growth or death. A give-and-take relationship exists between the ideal water temperature for fish production and the concentration of dissolved oxygen that will impact plant health. Given the constraints of temperature, dissolved oxygen should not fall below 5 ppm. Additional air pumps might be necessary for the fish effluent entering the hydroponic system.

Another big water quality parameter is pH. Ideally, pH should be 6.5 to 7.5. At this range, macro- and micronutrients should not be tied up and the fish will not be bothered. It is important to note that while the above mentioned parameters are critical to both fish and plants, there are other tests—such as for calcium, phosphorous, potassium, iron, etc.—that might be important in monitoring the “nutrient” solution of the fish-culture water. Be sure to use available resources in the form of university extension publications and various textbooks on aquaculture and aquaponics for specific details. It’s worth it, as aquaponics truly offers an efficient means of sustainably growing food sources for an ever-growing human population. MY

Venus Flytraps in

Hydroponics by Chad Garbet

Some people see the impossible as nothing more than a challenge. Venus flytraps are a bit of a challenge to grow hydroponically, but if you can get it just right, they make a gorgeous and exciting addition (or centerpiece) to your garden…

A lot of time and effort has to go into a hydroponic Venus flytrap—it’s not any ordinary plant. Checking the pH at least twice a day is usually a must, and a humidity dome helps a bit too since most carnivorous plants like the flytrap are found in bogs and swamps, so they like a moist climate.

Medium When choosing a grow medium for the flytrap, don’t try something that raises the pH too much. Certain hydroponic grow media are particularly great because they are pH neutral. A good mix to try is coco polymer covered with a layer of diatomaceous earth. One can also use soil in conjunction with a hydroponic system when growing flytraps since these plants will not get any form of root rot. Soil is a harder method, but it does pay off. The soil mix should consist of something like this: five parts peat moss, three parts silica sand and two parts perlite by volume. The silica sand helps with aeration and the formation of a healthy root system. To hold the

110

Maximum Yield USA | October 2012


soil in the hydroponic system, use a reusable coffee filter. Be sure to use one of the plastic ones so the water can flow through into the soil without making a big muddy mess in the reservoir. It’s still possible to lose some soil through the reusable coffee filter, so top ups every once in awhile might be necessary.

pH This is the most hassle of the whole hydroponic fly trap experiment. The Venus flytrap likes low pH—like most plants that live in bogs or swamps—so some pH down and a pH pen or strips are definitely needed when growing this plant. A constant pH of 4.5 to 5.5 is ideal, so one must check the pH at least twice a day (pH will slowly rise even when using a pH-neutral grow medium). If using soil, one will prob-

ably have to check levels three or four times a day. A bigger reservoir, however, can help fix this problem, often to the point that a gardener only has to check pH a few times a week.

Diet The diet of the Venus flytrap is extremely important. The roots of the plant don’t absorb nutrients, so that leaves all the work up to the flytrap’s head. Even though it’s called a flytrap, flies are the least of the plant’s diet. It mostly eats insects that crawl on the ground, such as ants, spiders, beetles and grasshoppers. The flytrap traps its prey and sucks the needed nutrients out of it with enzymes made in glands found in the plant’s head. It takes the plant several days to fully digest the nutrients from an insect; afterward, the trap will open

to reveal a depleted husk of an exoskeleton. It is an amazing sight to see the flytrap shut on its prey, trapping them into their impending doom and slowly digesting them over several days. It also makes the plant—which comes in a few different colors and shapes —a great interactive treat for company.

Light it Up Fifteen years ago, the big debate was whether or not to have a separate room for vegetative growth. These days, most growers know that a healthy vegetative garden is key to the flowering phase. So, with the trend toward raising more and healthier vegetative plants in order to increase the flowering garden, the need for more lights has risen as well. Growing with multiple lights

gives options like perpetual (or, staggered) harvests, side-by-side comparisons and bigger production. However, while many growers would like to take advantage of these options, not everyone knows how to meet the electrical requirements involved. Most rooms in residential homes have one or two electrical circuits with 15 A per circuit. If you have two circuits, this limits you to two 1,000 W lights or four 600 W lights. If you only have one circuit, you can get away with a single 1,000 W light or two 600 W lights. So, how do ambitious growers seeking numbers like four, six, or eight HID lights in a garden power these things without blowing breakers? That’s where lighting control boxes come in to play. The boxes are like beefed-up power strips for grow lights. Running on 240-V power, lighting control boxes allow growers to plug in multiple lights on a single circuit. These units have two power


cords: one big one that powers the grow lights and a small “trigger cable” for connecting to a timer. The trigger cable does not power any equipment; it simply triggers the on/off switch for the control box. Some control boxes omit the trigger cable and incorporate a built-in timer instead.

Voltage

The standard electrical outlets in your house operate on 120-V power. This is the voltage for powering toasters, televisions, computers, etc. Electric stoves, dryers and other high-powered appliances use 240-V outlets. The ballasts that power HID grow lights can operate on 120 or 240 V, but they must be wired specifically

Light it Up for the matching voltage. Many electronic ballasts can be used on either voltage with no switching or rewiring. Still, always check the label on the ballast to avoid damage. Higher voltage translates to lower amperage, and that allows for more lights. When ballasts are functioning with double the voltage, the amperage is cut in half. For example, a 1,000 W HPS light uses 9.5 A when plugged into 120 V. When that same ballast is operating on 240 V, the amperage is 4.75. That means you

116

can plug in another ballast without blowing a breaker. With a 30-A circuit at 240 V, you could safely run up to five 1,000 W lights. Would you rather grow with two lights or five? Just think about the harvests! Please note that this is not an electricity-savings technique. Grow lights use the same amount of electricity regardless of the voltage. Switching to 240 V will not reduce your power bill.

Power options

Go look at the cable on the back of your dryer. That is one big power cord. When you are dealing with 240 V, the large power capacity requires a large cable and outlet. One of the best ways to run a lighting control box is with a dryer cord. Many indoor gardens are set up near a laundry area so that dryer outlet is conveniently located nearby. If your basement has a dryer outlet, visit a quality hydroponics store and ask for a lighting control box with the


correct style of dryer cable to match your outlet. Mount the box and plug in the big power cord. The control box will have power outlets for the ballasts. Make sure the ballasts are set up for 240 V and then plug them into the lighting control box. The final step is plugging the trigger cable into a regular 120-V timer. The lights are powered through the dryer cable, and the trigger cable turns the lights on/off. With those four steps, you can run multiple lights with minimal effort. All of the lights are controlled by the single timer. Stove outlets can run even more lights. While dryer outlets often have a 30-A circuit, electric ranges typically boast 50-A outlets. At 240 V, the larger amperage allows growers to use eight lights with plenty of headroom. Just picture eight ballasts the same amount of plugged into one box electricity regardless and one timer.

Light it Up

If you are comfortable adding breakers to the electrical panel in your house, you can skip the outlet and simply hardwire your lighting control box. Simply run a length of solid-core cable directly from your breaker panel to your growroom and wire that cable to your control box. Note that you will still need to plug the trigger cable into a 120-V timer for on/off cycles.

118

What about laundry?

You might be thinking, “I’d love to use my dryer outlet or stove outlet for grow lights, but I use my dryer and stove!” No problem. Qualified repairmen can tap into either of those outlets and run a cable from your kitchen into your growroom, where the lighting control box is positioned. Your appliance stays plugged in, but the grow lights are wired to the same circuit. The important thing to remember, however, is to never run your appliance from that outlet while the grow lights are on. So, if your grow lights are on at night, do your laundry and cooking during the day. If you need access to your appliances 24/7, your best option is to hardwire the device to your breaker panel. This gives your grow lights a dedicated circuit, so no other devices can cause the breaker to trip. While I am not a licensed electrician, I am able to safely and legally install such devices in my home with ease. If you have no experience with electrical repair, get a qualified installer to add a circuit for the garden. So, don’t be afraid to run multiple grow lights. You will need plenty of fans, air conditioning and various growing supplies to go along with the lights, but the big harvests are always worth it. With lighting control boxes, adding more lights is a snap. Check your local grow store to see these boxes up close, and ask about various power options for your garden.

Boost When the Time is Right: Stage-specific Amendments by Eric Hopper

To get the most out of their plants, gardeners use nutrient additives, soil amendments and foliar treatments specifically designed for particular stages in a plant’s life cycle. Of course there are plenty of choices available, but this author wants you to know about the high-performance organic options.

120

Maximum Yield USA | October 2012

In order to increase production and optimize efficiency within their indoor gardens, horticulturists use various stage-specific nutrient amendments. The most common example of these is blooming and ripening additives designed specifically to boost a plant’s fruiting or flowering stage. Organic growers have also become more in tune with the benefits of stage-specific feeding programs. As our knowledge of organic supplements expands (along with our technologies used to extract the vital compounds), more stage-specific organic supplements are becoming available for the high-performance organic grower.

Guano

Bat and seabird guano have been used to boost fruiting and flowering since the beginning of indoor horticulture. High-phosphorous guano helps trigger flowering hormones within the plant and contributes to an increase in flower sets. There have been much advancement in the harvesting and extraction methods used by guano suppliers that help preserve the powerful elements that were lost due to outdated methods. One extraction method is guano tea, a liquid guano formula that is chock full of the beneficial nutrients and micro-organisms found in the guano. Liquid guano extracts like this one


are more easily absorbed by the plants and give growers the option to foliar or root feed. Unlike guano directly amended to the soil or medium, liquid guano also gives gardeners more control over dosage.

Kelp extracts As with guano, kelp suppliers have made much advancement in extracting and preserving the beneficial elements and hormones found in kelp. Although kelp was once rarely used as a bloom booster, some of the kelp formulations available today are specifically designed to do just that. Kelp extracts specific to bloom stimulation encourage rapid cell division during flowering and increase the production of specialized sugars found in fruit or flowers. It is important to select a kelp formula that is designed specifically for blooming, or you could end up promoting vigorous growth during your plant’s ripening stage. Kelp extract, if harvested at the correct time or in a particular manner, can also contain a variety of hormones that help trigger flowering and ripening.

Alfalfa extracts One of the newer organic extracts to hit the indoor horticulture market is alfalfa extracts. Alfalfa has a great nitrogen to carbon ratio, contains a variety of trace elements and has been shown to promote larger flowers. Alfalfa contains

triacontanol, a growth hormone that is thought to speed up the rate of photosynthesis by increasing the amount of CO2 that a plant can process. Many studies have shown an increase in flower-site production and overall yield with the use of alfalfa extract.

Protein hydrolysate Protein hydrolysate is a recent advancement in organic stimulators. Protein hydrolysate is essentially organic matter (usually soy protein) broken down into the essential L-animo acids. Amino acids are the building blocks for the proteins and enzymes that directly influence the structure and metabolism of plants. Supplementing a protein hydrolysate during a blooming period will enhance the utilization of other nutrients, boost the plant’s immune system, increase plant respiration and reduce stress. Protein hydrolysate is a multifaceted additive that increases fruit and flower production in many different ways. If you are going to try one organic stimulator, I recommend a protein hydrolysate formula. Whether growing conventionally or organically, bloom boosters play an important role in enhancing yields.

New and innovative products, teamed with advancements in extraction methods, allow organic growers to achieve harvests once only obtained by conventional methods. As more is learned about the intricate aspects of plant physiology, new products, methods and technologies will be created, allowing organic bloom boosters to even further evolve.

What Do You Know About the

‘Dew? by Frank Rauscher

In the garden, mildew is often confused with mold. However, they are very different problems and it is important not to mix the two up when it comes down to controlling the ’dew. So, here are a few hints on how to identify and control horticultural mildew.

122

Maximum Yield USA | October 2012



What Do You Know About the ‘Dew? Though horticultural mildew and general mold have many similar characteristics, the two are very different—particularly in color and texture. While both are indeed fungi, mildew is usually white or gray, while mold can be black, green, red or even blue. Mold often looks fuzzy or slimy and looks like a colorful plant growth covering the surface of a fruit. It is also often found on organic material like clothing, leather and paper, as well as inorganic materials and places like shower curtains. Though mold spores can survive in a dry environment, mold itself generally does not grow without moisture. Some types of horticultural mildew, on the other hand, can thrive in a relatively dry climate. If you search the web on the issue of mildew, you will likely find many websites that confuse varieties of mold with mildew. Some sites even provide incorrect information, so be very careful when you do your own research on this. To minimize the chance for confusion here, the only horticultural mildews that will be referenced are powdery and downy mildew. The others that might better fit into the mold category will not be mentioned.

Horticultural mildew Mildew thrives in a moist environment, but does not necessarily require high moisture. It is started by spores, which generally start off airborne.

Powdery mildew spores 124

Maximum Yield USA | October 2012



What Do You Know About the ‘Dew? The two main types of horticultural mildew are powdery and downy. Powdery mildew is mostly found on flowering plants and is propagated by an ascomycota-type of fungus. It typically gives leaves the appearance of having been dusted by cooking flour. Downy is found more on agricultural plants and is from an oomycota fungus. Its appearance is often like leaf spots, distortions, fuzzy patches and crystalline patches that look like sugar. Downy mildew is a primary concern for potatoes, grapes, tobacco and cucurbits (pumpkins, squash, cucumber, watermelons and the like). Recognizing and understanding the difference between powdery and downy mildew is essential if you want to be able to obtain control of these two extremely damaging pests in your garden.

Recognizing and understanding the difference between powdery and downy mildew is essential if you want to be able to obtain control of these two extremely damaging pests in your garden." Powdery mildew Characteristics: Light, powdery spore growth covering shoots, leaf surfaces and sometimes flowers. Controls: Garden sanitation, resistant varieties, spacing plants for good air movement, pruning infected tissue, providing adequate bright direct sunlight and appropriate fungicide sprays. Powdery mildew is one of the oldest plant diseases known and almost every gardener has seen or experienced this mildew on their plants (both ornamental and agricultural). The main symptom is thick webbing or a felt-like covering on the either side of the leaf or stem surfaces of the plant. This can make the plant look like it has been dusted with some sort of powder—hence the name powdery mildew. The leaves then can turn yellow, curl and die or fall off. This type of mildew can infect many different plants. It can be especially serious on crops like cucurbits, as well as a frequent threat to ornamental plants like roses, phlox, lilacs and crape myrtle. Though a bit less likely to be infected, beans, peas, lettuces, grapes and small fruit trees can also 126

What Do You Know About the ‘Dew? be affected by powdery mildew. Ornamentally, various types of grass and euonymus are also quite susceptible. Powdery mildew can seriously affect the health and vigor of a plant, as well as crop yield. Since different species and genera of fungi attack different varieties of plants, the actual identification and control might be tricky. The most common genera found around and in gardens are erysiphe, sphaerotheca and podosphaera. All powdery mildew fungi, however, infect the plant tissue in the same way. They send hollow tubes from a spore on the leaf surface into the plant and then suck out nutrients. The mildew then grows in a radius from the initial location of inoculation and after about four days, additional spores start forming in chains on upright stalks. The spores are what actually give the visual powdery effect. On perennial host plants like roses, fruit trees and soft fruits (like berries); mildew spores can even survive for more than a single season in those buds

What Do You Know About the ‘Dew? that have become infected. In some types of plants, certain special spores that enable the fungi to survive over the offseason are also produced. Powdery mildew fungus spreads rapidly when spores become airborne. If plants are grown too close together, the likelihood for the disease spreading is high. Even a small or singular infection can rapidly damage your whole crop. Low and shady locations lacking sufficient air circulation also provide the conditions in which mildew prefers to take hold and multiply, and so is sufficient to initiate an epidemic. Unlike most fungi, many powdery mildew spores do not need water in order to germinate. Some species do require considerable humidity, but the moisture provided on the leaf surface after a cold night followed by a warm day is sufficient. Though moist conditions increase the chances that your plants could get powdery mildew, preventing moisture is not enough of a preventative measure in itself. The most favorable outdoor condition for powdery mildew is when nighttime temperatures are around 60ºF and there is high relative humidity. The higher the nighttime temps, the lower the humidity required. Still, not all species require this much humidity and warmth, so keep an eye on your crop or you might lose a lot of yield and effort. Since the spores are sensitive to high heat and strong direct sunlight, you might be able to use these conditions to your advantage.

What Do You Know About the ‘Dew? Downy mildew differs from its powdery cousin in a number of ways. Unlike powdery mildew spores (which are spread by the wind), downy mildew is spread by splashing water. Also unlike powdery mildew, which appears on both sides of the leaf surface, downy mildew produces spores primarily on the undersides of leaves. Growth of these spores is often in a tree-like formation on branched fruiting structures (unlike the powdery mildew spores, which are produced in chains). The tops of leaves will have yellow blotches, while the undersides develop a faint frost of fuzz. Fruits on infected plants are often small and bitter—or, worse yet, they won’t even make it to harvest. There are various species and genera of downy mildew fungi, just as with powdery mildew, and these will attack different plants. However, all downy mildew fungi are in the peronosporaceae family. Downy mildew fungi prefer cool and moist conditions, which makes it less of a problem in arid climates. As such, when growing indoors, you’ll want to have good ventilation to avoid too much humidity in order to keep this pest away. When conditions are very humid, such as following a rainstorm or in a poorly ventilated indoor tent, spores will germinate quickly—often within several hours. The population of these spores on leaf surfaces might develop in several days under

ideal conditions of 65 to 75ºF. Below 40ºF, the spores won’t germinate, and exposure to 80ºF or above for 24 hours will exterminate the spores. Dry winds and warm, clear days also inhibit spore production. Roses, for example, are unaffected by downy mildew when humidity is less than 85%.

Horticultural mildew is a real nuisance to gardeners, both indoors and out. Gardening is a practice where frequent vigilance and maintenance have big pay-offs. Observing and controlling the mildew pest will help you maximize your yield every time.

As real estate prices soar and space becomes sparser, more and more people are turning to rental units within apartment complexes—residences that often have little to no yard space for gardening. But that doesn’t mean apartment-dwellers can’t still enjoy growing their own flowers, shrubs and produce. Matthew Carroll, spokesperson for Nursery and Gardening Industry Australia, says more and more apartment folk are finding ways to create their own little garden havens despite the limited space. It just takes a little time, creativity and imagination. “There are definitely space wars going on,” he says. “But there are plenty of ways to integrate green space into people’s lives.” Here are some of his top suggestions for creating an apartment-friendly garden retreat.

Even apartment-dwellers can reap the benefits of growing fresh food, flowers and herbs.

Say hello to herbs Carroll says herb gardens have become a trend among urban dwellers and it’s not hard to see why: they’re easy to maintain and can be grown indoors in a variety of tight spaces. Moreover, they’re visually appealing, aromatic and can make a great addition to any recipe. Even if you don’t have a balcony, herbs can still thrive on a windowsill or kitchen counter. All that’s really required for success is regular watering and adequate access to sunlight. And to make things extra simple, ready-to-grow herb kits are available for sale at a number of garden centers and nurseries. Tip: some of the easier herbs to start with are chive and parsley, as they both require less light than other varieties.

Get passionate about pots “Container gardening has become more and more popular,” Carroll says, adding there are now new varie-

ties of stylish, lightweight products available for purchase. “If you pair the right plant with the right pot, you can minimize your upkeep.” Your local garden center will be able to advise on which numerous plants or seeds are suitable for indoor potting. In addition to growing an appealing array of flowers and houseplants, Carroll recommends trying dwarf varieties of crops that will produce smaller fruits and vegetables, but still yield great results from pots and smaller garden spaces. These include apples, quince, cherries, peaches, plums, figs, avocados and blueberries.

Think vertical “If you don’t have a lot of floor space you can take [your plants] up the wall,” Carroll says, referring to the hot trend of vertical gardening systems.

The most innovative and aesthetically pleasing of these systems is the greenwall, a soilless, vertical patch of garden that grows along the flat surface of a structure. The plants used for greenwalls are those that can adapt and survive in difficult growing conditions, including ferns, grasses, herbs and perennials like the begonia. You can get tricks and tips on how to create your own greenwall at your local nursery center. There are also many landscaping companies that have begun specializing in these visually stunning gardens. An alternative to the greenwall is espalier, a vertical gardening method in which a lattice or wire provides support for branches and offshoots, so they can continue to grow upward. Finally, there’s always the trusty hanging basket, a space-saving gem that grows a variety of plants and flowers and even certain edible crops.

Good planning is as an important factor when it comes to thinking about your garden space as the location, water, soil, plant variety and weeding. So, before you start digging out your garden space or building your raised beds, take the time for observation.

136

Maximum Yield USA | October 2012


We often forget in our busy lives to take time out to observe our canvas before we start creating something on it. Just like a skier or snowboarder usually takes a moment to pick a line, gardeners should set aside a few moments before we begin working. Watch the direction the sun travels in and where its shadows are. Look at your landscape and observe the terrain. Good planning can save you lots of time, countless gallons of water and ensure a successful, abundant harvest. If you want to build your garden on a slope, take some time to do a little terracing or dig a swale (a swale is basically a ditch that allows excess ground water to collect in before slipping away down a hill with needed water and potentially useful nutrients). Choose a location that offers enough sun and shade for the plants you are growing. If on flat ground, make sure there is good drainage so water does not get stuck in the area you are looking to cultivate. If there isn't good drainage, either look for a new spot or use plants that like wet feet. Or, encourage better drainage by adding more porous soil or digging a trench around your grow space to redirect your water flow. One can save a lot of energy when working with the natural terrain instead of choosing a locale that one has to work against. Next, check your soil. The plants that are above ground are a direct reflection of the soil biology that is subterranean. Is your natural soil good for growing or does it need to be amended, or even replaced, in this space? Measure the pH and see if it matches the needs of your plants. If

not, buffer it so it does. If you need to create a soil mix, the DIY approach is definitely not the best way for beginning gardeners. There are many organic soil blends that can be purchased from your local gardening or hydroponics shop. Just make sure it is actually organic; also, it is even better if it’s inoculated with beneficial bacteria or mycorrhizae. Good soil biology is one of the most important factors to consider when testing the

nature as much as possible. Choose shade-loving plants for areas that are not soaked in all-day sun, and avoid planting cool-loving plants in the middle of a full-sun zone. However, remember that shade cloth is one way you can cool down the area you are planting during the summer months. When building a plant nursery, find a place with some direct sun and some filtered light as these conditions are great for plants that are still young and aren’t ready to be transplanted into the main garden. Your land’s water capabilities might also direct the plant you choose (based on the plant’s water needs). Mulching is a great way to provide a healthy environment for your plant. It keeps the weeds down, cools the soil temperature and retains more water in the soil. However, make sure to leave a little ring around the base of your plant so as to not build moisture on the stock and cause rot. Choose a mulch that does not reseed, and observe your mulch to make sure it is not becoming a condominium for local pests that might eat your food before you do.

When it comes to pests, the best start—if the plant is not infested—is integrated pest management (IPM). In this method, beneficial bugs eat pests. IPM can be started by adding certain plant species that will attract beneficial bugs to your garden—remember that monocrop planting does not create that biodiversity that nature yearns for—or by introducing the good bugs yourself.

Visual Identification of Nutrient Deficiencies In addition to soil and tissue analysis, visual identification of nutrient deficiency symptoms can be a practical tool for evaluating the nutrient status of the plant. In order to correctly identify the nutrient deficiency, one should be familiar with the factors affecting their development… Tip burn, chlorosis, necrosis and other symptoms of nutrient deficiencies can also be associated with other stresses. One example is plant disease. Some plant disease symptoms might be misinterpreted as nutrient deficiencies, but they can be differentiated by the distribution of the symptoms throughout

144

Maximum Yield USA | October 2012

the crop. If symptoms do not occur uniformly across the affected plants, it is more likely they are related to plant disease rather than to nutrient deficiencies. Under certain circumstances, apply-

ing chemicals to plants might induce symptoms that can resemble nutrient deficiencies. Knowing the spray history of your plants can help you in determining whether symptoms are related to the spray or something else. Also, you should pay attention to timing. If symptoms occur soon after a chemical was applied, they might be related to the spray. The distribution of the symptoms can give you another clue. In most cases, spraying does not cover the plants uniformly.


As such, note the path of spraying and compare it to it to the occurrence of the symptoms. Finally, salinity damages like tip burns might be misinterpreted as nutrient deficiencies. For example, marginal leaf burn could be interpreted as potassium deficiency.

Effect of nutrient mobility on deficiency symptoms The location on the plant where deficiency symptoms are expressed can help in diagnosing the nutrient disorder. Plant nutrients can be divided into two groups: mobile nutrients and immobile nutrients. Very mobile nutrients include nitrogen, phosphorus and potassium; and moderately mobile nutrients include magnesium, iron, and sulphur (mobility of this element varies with species). Immobile nutrients include elements like calcium and boron. The mobility of a nutrient in the plant affects the location of the deficiency symptom on the plant. Basically, nutrients are translocated by the plant to its actively growing parts, which are the younger leaves. Mobile nutrients can be translocated from older leaves to younger ones, while immobile nutrients cannot. As such, deficiency symptoms of mobile nutrients will first develop on the older mature leaves. Deficiency symptoms of immobile nutrients on the other hand will first show up in the newer growth because these nutrients cannot be translocated from the older leaves to the new growth.

Causes of nutrient deficiencies The first question you should ask yourself when attempting to identify the nutrient deficiency is whether the reason for the deficiency is a shortage of the nutrient in the soil or water, or other factors. In many cases, it might be more efficient to correct the cause of the deficiency rather than trying to correct the deficiency itself.

Irrigation schedule Overwatering affects the availability of nutrients to the plant. It results in lack of oxygen and a poor root system. The efficiency of nutrient uptake is therefore reduced and nutrient deficiencies, such as that in iron, might be induced. In addition, overwatering leaches nutri ents from the root zone. Under watering can also affect nutrient availability to the plant. When soil is dry, the movement of water through the soil is reduced. Since nutrients move with this water, their availability to the plant is reduced as well.

Nutrient antagonism and competition Often, nutrient deficiency symptoms are a result of interactions between nutrients. An excess of one nutrient can cause a deficiency of another because some nutrients have similar uptake mechanisms. This kind of interaction is referred to as “nutrient antagonism.” For example, excess potassium can interfere with the uptake of magnesium, and an excess of metals like manganese or zinc can induce iron deficiencies.

pH

induced when pH is higher or lower than the recommended pH range for individual plants. Fixation of nutrients is also influenced by soil pH. Fixation refers to the reactions of soil particles with nutrients, which render them unavailable to plants.

Summary and conclusions There are many factors that might affect the nutrition status of your crop. (However, remember that some nutrient deficiency symptoms might not be caused by nutrient deficiencies at all.) A visual identification of nutrient deficiencies can be used as a practical and quick diagnostic tool. Nevertheless, it has a major drawback: once deficiency symptoms occur, there is already a major effect on yield, growth and development.

The pH plays an important role in the availability of nutrients. The pH affects most reactions with soil particles and other nutrients. Micronutrients are most influenced by pH, but the uptake of nutrients like calcium and magnesium are also affected. Nutrient deficiencies are

Four Transplanting Mediums and Methods

It’s said that transplanting is one of the most stressful times of a plant’s life—for many, it can be a matter of life and death. And while a newly rooted 146

Maximum Yield USA | October 2012

clone’s fate depends upon a variety of factors, the most important is the handling and care it receives right after going into a new home.



Moving on Over Just like a newborn baby, clones should only be taken from one environment to another when they are strong, healthy, have an ample supply of quality nutrients and are in nurturing, caring hands. And just like a baby, clones’ lives are in your hands, so it’s up to you to choose a home where they can grow and thrive to their fullest potential. There are so many new homes to choose from for these little babies, too! From traditional soil to rockwool and coconut fiber, the mediums can be tailored to fit the plants’ needs, depending on the available space and environment. So, here are a handful of the most widely used grow mediums, as well as tips on how best to transplant your little babies to best ensure their future success. Keep in mind that due to the stressful after-effects, it’s ideal to limit the frequency of transplants. So, if your plant’s ultimate home is a 10-gal. pot, transplant it directly into that container once it’s rooted.

Traditional soil Soil is so...earthy. It’s natural, it’s the medium in which many of us first learned to grow fruits and vegetables and it’s forgiving. It’s one of Mother Nature’s greatest gifts, and is many plants’ innate, native home. And it can be used at ground level, or gathered into containers for a more mobile gardening experience. Transplanting into soil requires a bit of finesse, but is still simple enough for a child to maneuver. You’ll want to do so

when the roots are relatively short—about 2 to 4 in. long— as opposed to waiting until they’ve become lengthy, which is preferable in hydroponics units. As the roots grow longer, they can also become tangled in the cloning unit and can suffer damage when removed. As well, if such mangled messes are put into soil without being separated, the likelihood of root rot killing off the plant increases. So, stick with the short-rooted clones for soil transplants; anything else will just cause unnecessary frustration. When it comes to brand type, it’s generally a matter of the plant species, personal preference and whether it’s nutrient-rich or poor. While some people prefer nutrient-free soil (with which the control over the plants’ diet is in the hands of the grower), you ultimately just need be sure it’s fresh, free of pests and disease, and reputable. When watering your newly potted plants, find the balance between being overly generous and stingy. Overwatering is a surefire way to promote root rot, disease and unhealthiness, and not watering enough is just as bad.

Moving on Over allows the plant to dry out quicker and pushes the roots to spread out for more water sources. Increase the watering as the plant grows, but only as needed and without drowning it. Speaking of roots, another way to increase your plants’ success rate is to use mycorrhizal fungi—which puts a blast on the roots’ nutrient uptake— while transplanting.

Coconut fiber This is a truly organic growing medium that’s recently

grown in popularity. For good reason, too—it’s made from coconut husks and shells, has an amazing ability to retain water and oxygen, is high in root-stimulating hormones and protects plants from a host of issues, including root disease, pythium and fungal infections. An added organic perk is its biodegradable qualities and nearly neutral pH. It can be composted after use, is renewable and doesn’t damage the environment. Coconut fiber is also referred to as palm peat, cocopeat, cocos, kokos and coir, and is commercially available as compressed bricks (it expands when water is added). It can also be found in loose or dried forms. This product can be mixed with other growing media, including soil and hydroponic systems, and some growers blend it with perlite or expanded clay to aid in drainage. When preparing to transplant your rooted clones into coconut fiber, it’s important to remember that quality pays off in the long-run. So, don’t be cheap; buy reputable, healthy stuff. Some not-so-quality brands can have high sodium content, which isn’t ideal for plants. Also, wash the coco prior to using and get the “double-washed” coconut fiber if possible. And like any transplanting method, be gentle with the plants’ delicate roots.

Expanded clay This growing medium is incredibly popular due to its versatility and amazing ability to hold oxygen and nutrients while being lightweight and nearly inert. It’s pH-neutral, releases virtually no minerals and is ideal for growing rooted clones and motherplants. The pellets can also be reused and is therefore considered an ecologically sustainable growing medium. Expanded clay can be mixed with other growing media to increase the oxygen retention, and the pebbles are best suited for net pots, drip irrigation systems, water culture systems and ebb and flow systems. 150

Coconut fiber is biodegradable and pH-neutral, perfect for eco-conscious growers transplanting clones.

With roots that are at least 1-in. long, rooted clones should be handled gently and placed into clean clay. This means thoroughly washing new pebbles until the water runoff is clear. If reusing the medium, clean with a sterilizing solution, remove any dead roots and rinse. Also, for a thoroughly clean job, use a bleach–water solution or hydrogenperoxide–water solution for optimal results.

Rockwool

152

Maximum Yield USA | October 2012

Comprised of spun rock and sand, rockwool is a relatively new growing medium that has an incredible ability to retain water. It also holds onto air, making it ideal for newly transplanted clones’ vulnerable roots. It comes in a variety of shapes and sizes. The medium, which originated in Denmark, does have its drawbacks and criticisms. It never decomposes, can be hazardous if its fibers or dust particles are inhaled, has a high pH and has been referred to as “the Styrofoam cup of hydroponics.” Harsh. Nonetheless, growing medium preferences are based on what fits best for the situation at hand. Rockwool allows for newly rooted baby clones to be transplanted rather quickly after developing (they can have roots 0.5 to 1.5 in. long). Speaking of size, short and sweet is key here. The sooner the plants are transplanted after roots have developed, the better. At between 0.5 to 1.5 in. long, they can be transplanted into 1.5-in. cubes (or larger ones, if desired). Be careful as well when separating the rockwool cubes from the mat. Use scissors and wear gloves, as the fibers can latch onto and dig into your skin. Remember, it’s spun rock and sand and you would not want those materials on or in your body. When transplanting, split apart the rockwool and gently pinch back together around the roots. Or use a large cube, maybe 4 in., and place the cutting in the center indentation and fill with loose, shredded rockwool.


Rockwool

allows for newly rooted baby clones to be transplanted rather quickly after developing (they can have roots 0.5 to 1.5 in. long).

Whatever you do, however, don’t squeeze, squish or otherwise manipulate the cubes’ shape, as it can disrupt the air/water balance. Depending on the stress caused by the move, consider misting the plants right afterward. While not a necessity, it can’t hurt and it will limit undue stress. When watering, pH test that stuff to between 5.5 and 6.5, as rockwool inherently has a high pH. Then dip the bottom half or quarter of the cube into the water, allowing it to uptake a healthy amount without becoming soaked.

Recycled glass foam This medium is made from recycled glass beverage containers that are ground into a fine powder before being combined with a natural foaming agent and heated in kilns. The result is highly porous pieces of glass foam aggregate that provide an effective ratio between aeration and moisture. When irrigated, water is held in the substrate’s micro pores, but quickly drains through the macro pores to allow fresh air to flow through the substrate. Since this medium is made from vitreous soda lime glass, it has a naturally high pH and must be buffered before use. Once stable, simply fill half your container with glass foam, then take your seedling with the substrate still attached to the roots, hold it in the container and fill up the rest of the pot with more glass foam. Then irrigate immediately. The fate of your newly transplanted clones is in your hands. Their success is dependent on you choosing the right medium where they will grow and thrive, and giving them the best care after they are transplanted. Maximum Yield USA | October 2012

Tips and Tricks

Ocean of

Air by Grubbycup

Outdoors, plants live in an ever-moving ocean of air; however, once they’re brought inside, gardeners must find a way to replace this life-sustaining breeze. An ocean of air washes over and through plants that are grown in a natural setting, such as a meadow. Tides of air currents even out the environment; they normalize temperature and humidity, wipe away excess oxygen and bring in needed carbon dioxide (CO2). When a plant is brought indoors, however, this free flow of air is cut off by walls. Plants grown in still air tend to sit in a cloud of oxygen—thus not receiving enough CO2—and to have more problems with molds and insects. However, a good gardener will replace what is lost—in this case, moving air. Moving air helps dry excess moisture before it 154

goes stale or encourages mold spore growth. In a garden, nothing good grows in stagnant water. As such, there must be enough air circulation to dry out spills and excess moisture to maintain a healthy growroom. Moving air is also useful in controlling a growroom’s temperature. When lowering your room’s temperature, it is often more efficient to vent off the hot air than try to dilute it with cold air. Also, try to remove the hot air close to the heat source so it can’t transfer much of its heat to the rest of the surrounding environment. For example, a 1,000 W HID light puts out a lot of energy, and passing the heated air though a vented hood can quickly remove from the room. In an ideal situation for cooling, outside air is brought in, run through ductwork to the hood, passes through the hood, and is returned by ducting to the outside. The first fan in the system should either be connected to the light hood, or at least be near the lamp to remove the worst of the waste heat. When designing your ducting, keep in mind that wide turns are better than sharp turns, and that the hot air you are


trying to get rid of rises. Also, it is best to run the ballast outside the garden so its heat doesn’t contribute to the overall room temperature. If the heat from the lights can be dealt with, then ambient room environment can be controlled with much less effort. If the area needs additional cooling, vent off the air from the hottest part of the room. Depending on how air-tight the garden is, a passive air vent might be required to replace the vented hot air. This incoming air should be taken from a cool source—for example, cooler outside air or air-conditioned cold air. Solar-powered fans can also be used to give an extra boost to ventilation systems during the hottest part of the day without adding to your electric bill (if needed, this should be the second fan in the system). Speaking of fans, in a basic three fan set-up, the first fan should vent the lights, the second should vent the garden and the third should circulate the air within the garden. Keep in mind that the room itself needs air circulation as well, both to encourage evaporation and to supply fresh CO2. CO2 is sometimes added to the environment artificially, although my preference is for the gardener— who is as much a part of the system as

anything else—to spend time in the garden and contribute breath to the system. (If you think your garden isn’t getting enough CO2, consider bringing a friend in and do some breathing together. Human beings are fairly large animals, and generate quite a bit of carbon dioxide when exercising.) To calculate how many cubic feet per minute (cfm) of ventilation you need, calculate the size of the room in cubic feet by multiplying the height, length and width of the room. For example, an 8 by 10 by 10 ft. room is 800 sq. ft. A single 800-cfm fan would move the room’s area worth of air every minute, and a 400-cfm fan would do the same every other minute. Fans are usually rated at a low load, so ducting will reduce cfm dramatically. Every situation is different, and common sense must be used. In a cold winter room, heat retention might be more important than removing waste heat. We live in an ocean of air, complete with currents, flow and volume. By giving plant the fresh air and airflow they need, not only will the plants be happier, but it can help keep molds and moisture-loving insects like fungus gnats at bay.

Whatever the reason, excessively hot temperatures are not favorable to an indoor gardener. Hot temperatures break down plant immune systems, leaving gardens susceptible to attack and infection. If not properly equipped, a system designed for perpetual harvest can begin to collapse as a result of stress input on the plant. Debilitating stress can be caused by a number of factors, including insects, molds, blights, mildews and viruses. Root aphids, the spider mites of the new millennium, are a particular problem. They will infest all grow mediums from rockwool and hydroton to coco and soil, and they crawl to and from containers, pots, cubes and trays, as well as fly about. These little suckers have taken over many gardens; in fact, younger adolescents will devour root systems in hours, turning healthy vibrant plants into wilted standing sticks overnight. The damage ultimately results in root disease, which many gardeners often mistake for the primary cause of failure rather than the root aphid itself. As such, inspect for root aphids

susceptible as much as beginner growers, so practice consistency, develop methods and implement follow-through. Despite heat waves and bug swarms, your garden should stay insect- and disease-free with the proper inputs and routine practices.

No Problem One of the greatest benefits of ventilation is the ability to exchange heat from indoor gardens with fresh, cooler air from the external environment. But the when outside becomes hotter than the inside of the growroom, cooling becomes a different ball game…

Given the record heat levels that affected much of the world this past summer (especially in my drought-laden area), the topic of ventilation has been coming up in conversation much more often than usual. One of the greatest benefits of ventilation is the ability to clear excess heat from indoor gardens by exchanging it with fresh, often cooler, air from the external environment. However, when external conditions heat up a lot, it isn’t uncommon for growers to use a combination of oscillating fans and air conditioning units to decrease the indoor garden temperature and maintain it within the optimal range.

While this is an excellent stop gap solution for a couple days of extreme temperatures, growers will begin to feel the pinch in their wallet or purse as power consumption and bills grow quickly if these conditions persist for extended periods of time. If you find yourself in these circumstances, all hope is not lost. By perusing a sampling of current horticultural academic papers, a quick blueprint can be used to increase the size and quality of your yields without breaking the bank.

SET A MAXIMUM TEMPERATURE THRESHOLD Don’t try to stay in the lower portion of the optimal plant-growing temperature range. If you absolutely need supplemental air conditioning, try to set a maximum threshold. That way, the growroom temperature will not be allowed to pass a certain point, say 85ºF. Take note that the increased ambient air temperature will likely cause your media to dry out more quickly than under normal conditions. INCREASE IRRIGATION FREQUENCY Regardless of which type of irrigation method you are using (drip, flood-and-drain, top-feed, etc.), your plants can benefit from increasing the number of irrigations

they receive. Researchers have found that, in general, plant roots consume dissolved oxygen at a faster rate than both nutrients and water, which can boost growth with frequent replenishment.

LOWER NUTRIENT CONCENTRATIONS Nothing will be gained by maintaining relatively high nutrient concentrations in a fertigation solution that is applied frequently. Instead, the potential for developing nutrient toxicities and lockout increases as unused nutrients build up in your media. Quite literally, sometimes less is more. In studies of lettuce and pepper production, horticultural researchers have found that phosphorus uptake is actually increased when lowconcentration solutions are combined with increased irrigation frequency.

SAVE MORE BY STOCKING MORE As seasoned hydroponics growers know, you can’t really have enough water in stock for your grow. Rather than buying water or running your reverse osmosis system as needed, try to stock up your supply and store it in your indoor garden. This practice is often used by commercial greenhouse growers to lower high temperatures as water has an amazing capacity to act as a heat sink.


DO YOU KNOW?

1.

Most rooms in residential homes have one or two electrical circuits with 15 A per circuit.

Higher voltage translates to lower amperage, and that allows for more lights. When ballasts are functioning with double the voltage, the amperage is cut in half.

3.

Powdery mildew is mostly found on flowering plants and is propagated by an ascomycota-type of fungus. Downy is found more on agricultural plants and is from an oomycota fungus.

Below 40ºF, downy mildew spores won’t germinate, and exposure to 80ºF or above for 24 hours will exterminate them.

The most common genera of powdery mildew found around and in gardens are erysiphe, sphaerotheca and podosphaera.

The mineral premixes used in fish diets in aquaculture contain most of the macro- and micronutrients needed for plant growth and development.

In warm climate greenhouses with mature crops, the rate of ventilation required to simply remove the heat from incoming solar radiation, supply fresh CO2 for photosynthesis and lower humidity from crop transpiration is often as high as one complete air exchange per minute.

If heat and humidity are combined with a lack of airflow, plants stagnate, physiological disorders become common place and fatalities can occur.

In aquaculture, salmonids (trout and salmon) require pristinewater-quality parameters.

Ventilation is an essential component of evaporative cooling as the evaporation of water causes humidity levels to rise.

For fan and pad cooling to work at maximum efficiency, it is important to keep the growing area as air tight as possible.

MAKING

Water Logical

Pure water is as important for plants as it is for humans, and Hydro-Logic is all about making pure water affordable, accessible and easy to produce for the masses. Here, Jennifer Casey chats with Maximum Yield to discuss how the company does it. Maximum Yield (MY): Tell us about how Hydro-Logic got started and who the people behind the company are. Jennifer Casey: Hydro-Logic was started by Rich Gellert, a dedicated gardener who was unhappy with the results he was getting from his unfiltered well water. Other RO systems on the market were unable to produce the amount of water Richard needed, so he came up with something better. [After first] teaming up with Santa Cruz Hydroponics… Richard formed Hydro-Logic. MY: Tell us a little about the company’s philosophy. Jennifer: Our philosophy here at Hydro-Logic is all about accessibility. We aim to make it easy and affordable to get pure water to your garden, business or home. We are constantly on the lookout for the latest in water technology, as well as being deeply involved in hydroponics and gardening. 170

MY: What is an RO machine? Why do I need one? Jennifer: RO stands for reverse osmosis, which is the selective diffusion of a liquid through a membrane. A membrane is a thin sheet of polymer that allows only pure water molecules through. The contaminants in the water… are washed away by waste water. If your water is over 150 ppm, you need RO because high ppm in your water will interfere with your feed schedule. Additionally, some of those contaminants could be chemical pollutants. MY: From the information on your website, RO filters seem to do everything a de-chlorinator does and more. So, why would someone need by buy a de-chlorinator? Jennifer: Yes, our RO systems do everything a de-chlorinator does, but our de-chlorinators do not do everything our


RO systems do. Although they won’t decrease your ppm, they will remove chlorine and chloramines. They also remove or reduce some heavy metals and volatile organic compounds that can harm your plants. If your ppm is under 150, a de-chlorinator might be all you need. MY: What is a UV sterilizer kit? How is it similar and different from a more traditional water filter? Jennifer: The UV sterilizer kit is meant to be used in combination with a de-chlorinator/sediment filter or RO system in order to kill bacteria. The UV sterilizer is simply a way to expose the contaminated water to a strong source of UV light, which renders the bacteria harmless by destroying its ability to reproduce…it sanitizes the water without the use of harsh chemicals. MY: What’s your most popular unit for hydroponics and indoor gardens? Why do you think that is? Jennifer: The unit flying off the shelves fastest is our Evolution 1,000. This unit is popular due to its high (1,000 gpd) flow rate. The Evolution has a much longer membrane life than the smaller units, so…the increased cost will amortize over the life of the unit. Gardeners know they need pure water. To put it simply: the Evolution is the most popular because it makes the most sense and our customers are smart. MY: How long does a filter last, on average? Jennifer: The actual carbon and sediment filter life varies from system to system. The Stealth RO 100 eco-green carbon filter needs to be replaced every 1,250 gal. of

pure water used, while the Big Boy de-chlorinator’s larger carbon filter is good for 25,000 gal. The membranes in our RO systems are rated over time rather than per gallon, as membrane life is highly dependent on source water quality. Our membranes are rated up to 1,000 ppm (the SuperLogic is up to 5,000 ppm). We have no way to guarantee membrane life because source water is different from site to site. MY: You’re slogan is “Pure water’s not magic…it’s logic.” Can you explain how pure water is logical? Jennifer: While the science of water filtration might only seem logical if you’re an expert, it’s actually the use of pure water for your plants that our slogan is referring to. Just as drinking water with poisonous, biocide contaminants is bad for your body, giving your plants poisonous water is bad for them. It’s that simple: living things need water, not all of the other chemicals that happen to be in water these days. MY: Is there anything exciting happening in the R&D stage that you are at liberty to tell us about? Jennifer: The SuperLogic is all done with the R&D stage, but it’s new enough that it bears mentioning. If purchased with the optional softener, the SuperLogic gets four parts pure water to one part waste water! Without the softener, it gets two parts pure water to one part waste water. Another exciting product is our Filox filter for removing all that pesky iron. We have whole-house Filox filters available now, but we are testing smaller units made to work in the garden with your RO system. Still in the true R&D phase is a boron-removal system.

Co-owners Kurt Borngesser and Alan Rosenthal

“Find out what you do best, and do that better.” It’s a piece of advice Alan Rosenthal, co-owner of HydroHarrys, got from his uncle years ago and it’s one that has served him and his business partner, Kurt Borngesser, well. Alan and Kurt met at the Rosenthal’s family-owned gardening store, where they both worked for over a decade. Although that workplace focused more on outdoor gardening, Kurt and Alan were introduced to hydroponics through the small amount of merchandise the store did carry. The future business partners recognized the potential of the indoor gardening market and they eventually realized that what they did—and liked—best was hydroponics. So, they decided to specialize and they left the family store to open the indoor gardeningfocused HydroHarrys. “It was a natural progression,” Alan explains.

Kurt and Alan opened up their first store in Walled Lake, Michigan in April 2011; quickly followed by a second, larger location in Hazel Park that summer. The transition into their new business venture went relatively easy and things went together quicker than expected, Alan says. Both the cities of Walled Lake and Hazel Park responded well to HydroHarrys, so getting licenses, leases and other paperwork through was a breeze. Also, the infant stores already had a built-in customer base from the family gardening store, which closed soon after they left due to retirement. Alan also credits the ease of starting up HydroHarrys to a personal motto he follows: Under promise, over

deliver. More or less, this means to set low expectations as a buffer against disappointment. However, that isn’t the same thing as lack of ambition or drive, Alan explains. One still must strive to do a job as well and as timely as possible. The point is to exceed the expectations you have set. In the case of HydroHarrys, Alan says he didn’t expect great things right away. As such, he was exceptionally happy with the straightforwardness and relative success of the store when it first opened. Alan also says he tries to keep to this motto now that the store is in its second year. He gives an example from the area of customer service: if a job or an order is going to take two days to complete, one should take an extra day or two of leeway, just in case. Then, when the job does indeed take only two days, both the store and, most importantly, the customer are happy. It is this dedication to keeping their customers happy that Alan feels sets HydroHarrys apart. Indeed, Alan credits and measures HydroHarrys’ success on their high level of customer service. It seems like both of the stores’ customers are regulars and about nine of 10 new visitors will come back, he says. That customer loyalty is in part thanks to the fact the two stores’ six

HydroHarrys is up against a “healthy” staff offer attentive and individual amount of competition from the area’s relationships with every customer that other hydroponic stores, but Alan and comes in. Since all of the staff shares Kurt don’t really worry about what a passion for indoor gardening—Kurt its competitors are doing stock- and and Alan are themselves master garbusiness-wise. Instead, Kurt and Alan deners—each member has, or at least like to concentrate on making their knows where to get, the knowledge own business better. their customers want. HydroHarrys also has a policy to never sell anything that is unnecessary; if customers come in with problems that can be fixed at home, the staff will prescribe home remedies instead of selling them something unnecessary. The hope is that customers will remember the service and come back to the store when they do need to buy something. “We’re not in this for a quick buck,” says Alan. At the moment, HydroHarrys stocks over 1,000 products, including those from big names like General Hydroponics, FoxFarm, Technaflora and Botanicare. As their website says, “If it’s not here, which is unlikely, just ask us and we will go out and get it!” Indeed, HydroHarrys is constantly adding new products and looks to its customers for guidance. These days, the number one thing people ask for is soil; however, that could Joel Rebar, Hazel Park manager change at any time. Maximum Yield USA | October 2012

The Battle Issue

Sometimes gardening can feel more like a battle than a relaxing pastime. No matter how experienced you are, the threats of insects, mold, viruses, diseases and more are always just around the corner. So, arm yourself with knowledge and protect your plants’ health. Learn how to combat mildew (not to be confused with mold), identify and control pests, and fight exotic water contaminants. Some of the other articles rounding out this issue include: • The Increasing Practicality of Indoor Food Production • The Benefits of Natural CO2 • Calculating the Success of a Crop • And more!
