LETTERS TO THE EDITOR Kudos!
Thank you Maximum Yield and Matt LeBannister for answering my question on companion planting for pest control and nutrient balance in the January issue of Maximum Yield. You gave me just info I was looking for! In particular, I’m excited about your suggestion to plant multiple varieties of tomatoes, basil, etc. (not only because it helps boost the chance that one type might survive a disease/pest outbreak, but I never really considered planting more than one variety of each herb and veggie before). I can’t wait to try out your tips when I plant my garden this coming spring; it’s sure to be a tasty season! Thanks again, JD You’re very welcome, JD! The team of experts here at Maximum Yield are always happy to answer any indoor gardening questions you might have. Keep sending them in—and have your friends send in theirs, too—to editor@maximumyield.com. You can also ask questions through our Facebook page.
Greetings,
One of the things I miss the most is picking up my copies [of Maximum Yield] at the local grow shop. I have learned so much from you over the years. When I come home my first stop will be to grab the latest issue. Thanks, David

In our October 2012 E-News, we asked, “What growing techniques and products do you plan to use in the new year?” This is what one of our readers had to say: Dear Maximum Yield, I have a greenhouse and a separate indoor grow room. I am interested in using both of these spaces to develop a hybrid system that utilizes the strong points of each growing space. What should I do to get the most out of my growing spaces? How should I move forward and what type of system should I build? Lawrence Tandy There are many types of indoor and hydroponic gardening methods available today. It‘s tough to say which system will suit you best. Aeroponic, deep water culture, ebb and flow, drip… the list goes on. It’s really up to the individual to assess their own needs and capacities and develop a system that suits them best. You may want to develop a system for each of your grow spaces as they will have different lighting, ventilation and environmental control issues. This month’s informative articles offer a lot of information about the various options open to the new grower.

ASK THE EXPERTS
I’m a woman trying to be a thoughtful wife, but I don't really know anything about indoor or outdoor processes. My husband and I live where it snows and is cold more than half the year. He is currently growing indoors but wants to move outdoors with a greenhouse. My question is: what kind of system can I get him so it can go inside and outside without a drop in performance and fruit quality, using the same system? He prefers a more natural light system and natural feeding, but we also need to watch the bill side as well! Please help! Leticia Ryan M. Taylor
What a great gift idea! I hope this thoughtful response will satisfy a thoughtful wife. Without knowing the size of the growing area and number of plants your husband will be growing throughout the year, my answer is focused rather on the key information you provided: the desire to build a flexible, low-cost growing system that can utilize natural (that is, organic) nutrients. While there are a number of commercially made systems available that meet your criteria, I would recommend a do-ityourself project to save as much money as possible. Two types of systems can be built relatively cheaply, will be highly effective indoors and out and can effectively deliver organic nutrients: drip irrigation and the nutrient film technique (NFT). Drip irrigation technology (e.g. tubing, barbed tees, emitters, etc.) can be reconfigured in an infinite number of ways depending on your changing growing conditions. Combined with a suitable substrate, drip irrigation can provide organic nutrients provided that the tubes are flushed periodically with pure water to prevent the build-up of non-soluble material.
20
Maximum Yield USA | February 2013
With NFT, plants are grown in tubes or channels where a thin film of nutrient solution passes constantly across the bottom of the root zone; this perpetual motion sufficiently oxygenates the solution—decreasing the probability of an outbreak of bad bacteria—and provides plants with enough nutritious moisture in the event of an otherwise devastating heat wave. Both irrigation systems can be used to grow small or large plants. With drip irrigation, your choice of container size will largely influence the ultimate size of the plant, whereas with NFT, your choice of tube (e.g. pvc pipe, vinyl gutter) will dictate the ultimate size of the plant. One key thing to keep in mind is that planting arrangements are ultimately infinite with drip technology, whereas plant spacing is typically static in NFT once the tubes have been drilled. Unfortunately, this answer is vague, primarily because hydroponic horticulture as a field of study is so complex. But take my word for it: you really won’t go wrong if you invest in a basic drip irrigation or NFT system. Ryan M. Taylor

Scientists Seek Genetic Diversity in Watermelons Scientists are analysing the wild watermelon for genetic traits that might help develop cultivated forms that are more resistant to diseases. An international team led by Zhangjun Fei at Cornell University’s Boyce Thompson Institute for Plant Research identified 10 genes as candidates for making the fruit more resistant to plant diseases. Fei said the number of years it will take to cultivate more desirable melons with genetic sequencing technology is half that of older techniques. Once his team identifies a marker for disease resistance on the ancient melon’s genome, it is simple to check a new strain of melon for the same marker and know whether or not it will hold up to certain plant pests.

According to the researchers, this approach could improve efficiency of solar panels by over 50 percent. (Source: inhabitat.com)
Cheating Slime Mold Gets the Upper Hand A new study has found that a “cheater” mutation (chtB) in Dictyostelium discoideum—a free living slime mold able to co-operate as social organisms when food is scarce—allows the cheater strain to exploit its social partner. When conditions are right, the usually amoeba-like Dictyostelium behaves more like a fungus, producing a stalk and a fruiting body that releases spores. The chtB strain is able to reduce the ability of normal Dictyostelium to form spores so that when mixed in equal numbers with wild type Dictyostelium, 60% of the spores will be chtB. The chtB mutation appeared to be normal in all other respects. (Source: sciencedaily.com)

Finding Chicago's Food Gardens with Google Earth John Taylor, a doctoral candidate, was skeptical about the lists of Chicago’s urban gardens provided to him by local NGOs. So, he looked them up in Google Earth, using a set of reference images to determine visual indicators of food gardens. Of the 1,236 community gardens listed, only 13 percent were actually producing food. However, Taylor estimated that there are 4,648 urban agriculture sites in the city. This suggests that both backyard gardens and vacant lot gardens contribute substantially to Chicago's total food production. (Source: sciencedaily.com)

Helpful Ditches USDA scientists report that vegetated drainage ditches can help capture pesticide and nutrient loads in field runoff, giving farmers a low-cost alternative for managing agricultural pollutants and protecting natural resources. One study evaluated the transport and capture of the herbicide atrazine and the insecticide lambda-cyhalothrin for 28 days in a 160-foot section of a vegetated agricultural drainage ditch. One hour after researchers starting a simulated runoff event, 61 percent of the atrazine and 87 percent of the lambda-cyhalothrin had transferred from the water to the ditch vegetation. At the end of the ditch, runoff pesticide concentrations were generally non-toxic to downstream aquatic fauna. (Source: sciencedaily.com)

Boeing Uses Potatoes to Test In-Flight Wi-Fi Wi-Fi is now is now an easy payment away for passengers, but it’s not exactly as reliable as the connection you get in your own living room. However, Boeing has employed an interesting tool to help sort out the in flight Wi-Fi issues: potatoes. Apparently, water-logged tubers interact with electronic signal properties much like humans. So, Boeing filled the plane with sacks of spuds when testing how radio signals interacted with the plane's electrical systems, and now the company is using them to test and tune wireless signals so a stronger signal can be received throughout the aircraft in the safest way possible.

PRODUCT SPOTLIGHT ExHale Bags Photosynthesis is the process by which plant leaves make carbohydrates. Sunlight, CO2 and water are converted into carbohydrates and O2 by the action of chlorophyll in the chloroplasts of the plant. Plants growing indoors under artificial light often lack enough CO2 to efficiently photosynthesize. When plants are able to maximize the process of photosynthesis, the result is larger plants with larger yields. ExHale cultivates CO2 24 hours a day with no need to refill bottles or use expensive CO2 production units. The power of ExHale lies in the mycelial mass inside the vented cultivator. This mycelial mass cultivates CO2 and the microporous breather patch releases CO2 continually for up to six months. No need to turn it on or turn it off, simply place ExHale in your grow space and leave it alone to do its job. To learn more, visit a hydroponics store near you.

Phosphorus
Phosphite
First, plants need certain essential nutrients—carbon, hydrogen, oxygen, nitrogen, phosphorus and potassium—in large quantities. Nitrogen, phosphorus and potassium are sold in the market as fertilizers; they make up the N-P-K numbers [grade] on fertilizer bags. In terms of phosphorus (P), not all forms of phosphorus are available in the soil for plants to use, nor are all of the forms useful to the plant once inside. The main use of phosphorus in plants is for the formation of adenosine triphosphate (ATP). ATP is the energy-storing molecule (or gasoline, if you will) of the plant. Phosphorus is also used heavily in root growth and other biochemical processes. Phosphorus can come in many forms—each with a different function in the plant—and yet still be sold as fertilizer. It is important to know the differences between these products and their functions so you know what kind of results to expect from them. In fertilizers, phosphorus is usually in the phosphate form (PO4) and expressed as a percentage of equivalent P2O5. Phosphate fertilizers are made using phosphoric acid. It makes more sense to list the amount of phosphorus on fertilizer labels (as it is done in Europe), but the P2O5 equivalence requirement stems from an archaic law that is still on the books in the United States. Some common phosphate fertilizers are super phosphate and ammonium phosphate. Phosphate fertilizers are used in large amounts in horticultural, agricultural and turf applications and they are often blamed for algae blooms in rivers and lakes (water carries phosphates and nitrogen fertilizers to these bodies of water). The rapidly growing algae blooms suck oxygen from the water, thus resulting in large fish kills. It is for this reason that many states are regulating and limiting the amount of phosphorus products that can be applied to crops and turf as fertilizers. In fact, the Environmental Protection Agency (EPA) is considering regulating waste water effluent from greenhouses and hydroponics operations in the future to control their levels of nutrients released into municipal sewer systems and the environment. In other words, growers will have to become more efficient in their use of phosphate, nitrogen and other nutrients, so it will become more important in the future to know the various forms of these materials and how to use them correctly.
Phosphite (PO3) is a phosphorous compound that has one less oxygen molecule than phosphate fertilizer. Phosphite is made using phosphorous acid. The key difference between phosphite and phosphate is that phosphite has very strong fungicidal qualities, particularly against the water mold fungi phytophthora, rhizoctonia and downy mildew. This quality makes phosphites particularly attractive for hydroponics applications since the plant’s roots are kept in very moist and wet conditions for prolonged periods of time. Phosphites also have some fungicidal activity against fusarium, apple scab, phomopsis, colletotrichum leaf spot (anthracnose), uromyces, sclerotinia and xanthomonas. Conversely, phosphate fertilizer has no fungicidal activity.

understanding phosphorous acid products Phosphites are labeled and sold as both fungicides and fertilizers. The reason for the fertilizer label is that the phosphite will be exposed to oxygen and microbial action over time and, thus, transformed into phosphate fertilizer. The problem is that, according to some scientists, this process is too slow to be of any practical value (it takes at least six weeks). For example, bone meal is a form of phosphorus certified for use in organic food production, but you can imagine how immediately available to plants the phosphorus in bones might be—yet bone meal has no label restriction in this regard. Nevertheless, it is for this reason that thirteen states—California, Georgia, Indiana, Kentucky, Michigan, Minnesota, Missouri, North Carolina, Oklahoma, Oregon, Pennsylvania, Texas and Washington—do not recognize phosphites as a source of phosphate fertilizer. In these states, a phosphite with an analysis of 0-2825 would have to be labeled 0-0-25. In California, it would be labeled as 0-28*-25 (the asterisk is required since a state law was passed in 2006). So, there are often arguments about whether phosphites are really fungicides or fertilizers—sort of like the old Saturday Night Live skit: “It’s a floor wax, no it’s a dessert topping; actually, it’s both!” The mode of action in which phosphite materials control fungal disease is not clear, but it is thought that there is direct activity against the pathogen and an effect on the crop plant. Phosphites are known to jump-start the plants’ immune system by ramping up the production of phytoalexins. There is evidence for the existence of other lesser-known modes of action, thus making the formation of resistance to phosphites very unlikely (given that the pathogen has to overcome these multiple systems). It is for these reasons that phosphites are so effective for disease control and why there are literally dozens of manufacturers worldwide selling them as fertilizer and fungicide. Phosphites are routinely used in fungicide rotations to manage resistance. The phosphites belong to resistance management class FRAC 33. Phosphites are usually created by combining a strong inorganic acid (low pH solvent) with a strong inorganic base (high pH solvent) to form phosphite salts. Inorganic, in the chemical sense, means there is no carbon in the molecule.

Phosphites have another interesting characteristic: once absorbed into the plant they travel in both the xylem and phloem conductive tissues, meaning that they are transported to all plant tissues in a systemic fashion. Moreover, phosphites are readily absorbed by root, stem and leaf tissues, making for versatile application procedures (such as drenches, root dips, tree bark treatments, soil application, soil injection, chemigation and foliar and aerial application methods). And besides being useful during the crop season, many phosphites are labeled for post-harvest applications by either spraying the crop as it enters a storage bin or by using a vaporizing system. As a rule, phosphites are very safe for humans and the EPA often approves them as reduced-risk pesticides.

understanding phosphorous acid products
One side benefit of using phosphites is that they enhance root growth through root flushes. There is some debate as to whether this is the result of direct growth promotion of the roots, or a suppression of root-rotting fungi, leading to healthier and more extensive root systems. Phosphites have both curative and preventive action, so it is important to apply them preventively to get the full benefit.
Phosphonate In chemistry, any material with a carbonphosphorus bond is termed a phosphonate. The main beneficial feature of phosphonates is that they decompose or break down to become phosphites. One particular phosphonate product is made with aluminum, but—true to the phosphonates—this product must undergo a chemical conversion after application to produce phosphite. Ethylene gas is released during the conversion process, which can be a problem at times as ethylene gas controls the ripening of fruits. Moreover, aluminum can be toxic to plants in acidic soils and it can compete with other micronutrients in the soil, thus causing nutrient deficiencies. Although this type of product has been in the market a long time and is effective, many growers like to buy products where the ratio of ingredients that are usable by plants is maximized (for example, potassium phosphite, calcium phosphite, ammonium phosphite and others are preferred as potassium, calcium and ammonium are all used by plants). Therefore, the term phosphonates is often used or confused as an umbrella term for all phosphiterelated products, but this is a misnomer since inorganic phosphites (phosphite salts) contain no carbon.

Consistency is the key
Further increasing the complexity, there are often multiple subspecies that can also greatly vary in their requirements for optimal growth. The good thing for horticulturalists is that although plant species vary greatly in their specific requirements, almost every plant species on the planet thrives with consistency. So, in order to help your plants thrive, it is important to understand the parameters required to supercharge the plants throughout all stages of growth.
Seedlings Although seedlings from different plants will vary greatly in their requirements for optimal performance, most fast-growing annual seedlings share the same basic needs. By following some general rules of thumb, a gardener can achieve seedling success fairly easily. During germination, the majority of summer plant varieties require warm conditions (usually 72 to 80°F). Spring or fall varieties of flowers or vegetables require lower tempera-
tures for germination. A seedling heat mat is a must-have for any indoor horticulturalist. This device, teamed with a thermostat, ensures consistent temperatures for even the most novice of growers. A consistent temperature throughout the germination stage is crucial to root development. Many plant varieties also benefit from higher humidities during the early stages of seedling growth. A humidity dome, plastic bag or any other device that can be used to raise the humidity level around the seedling is beneficial. Unlike cuttings and clones, seedlings usually only require high humidity for the first day or two and then can acclimate well to the surrounding environment. Nutrient requirements for seedlings are generally one-eighth of what is required for a mature plant of that particular variety. Most potting soils will contain more than enough nutrients to start seeds. If you are using an inert medium, add a very diluted fertilizer. You can use a diluted grow fertilizer (one-eighth strength), although few seedlings require high nitrogen at this early stage. Many horticulturalists supplement a blooming fertilizer at one-eighth strength to their seedlings with great success.

Cuttings Most cuttings have similar requirements to the seedlings. Horticulturalists need to pay special attention during this stage of growth. Cuttings are more sensitive to large temperature and humidity variances. Cuttings are usually most successful if they have their own grow space (note that some plant varieties are simply easier to clone than others). This is not to say that you cannot successfully grow cuttings in a vegetative room alongside other plants; however, having a specific place to grow cuttings allows the grower to have more control over the atmospheric conditions. Still, most plants have a range of desirable conditions that are almost universal when discussing the cutting process. The temperature requirement for most cuttings is between 72 and 82°F, with the sweet spot usually right around 78°F. A heat mat can be a lifesaver in keeping consistent temperatures throughout the cutting process. In environments where temperatures stray too far from the ideal range,

Growers should utilize humidity domes, ultrasonic humidifiers or any other device that can keep the humidity between 80 and 100% for the first five to seven days of the cutting process.

less than desirable results will occur. If temperatures are too low, the cuttings will enter a state of suspended animation—that is, they will appear green and healthy but will never sprout roots. Eventually they will die or rot. Cuttings grown in temperatures that are too high usually soften and rot within a week without producing any viable roots. This can be a problem for growers using aeroponic cloners in atmospheric conditions that are too warm. The submersible pump in aeroponic cloners produces heat that, if left unchecked in an already warm environment, can put the water temperature above the desired range. This can be rectified by placing the cloner in a cooler environment or cycling the pump. A cycle timer can reduce the heat created by the pump by allowing it to cool between cycles. Sophisticated cycle timers allow the grower to set the on and off time down to the second or minute. A basic fifteen minute increment timer can work in a pinch for a grower with a hot cloner. Consistent humidity is another crucial parameter in the cutting stage. Most plant varieties require high humidity levels for the first week or so. This is because
70
Maximum Yield USA | February 2013

the leaves still transpire moisture the way they did when they were part of the whole plant. If a cutting transpires more moisture than it is able to replace it will wilt and die. In a high-humidity environment a cutting can retain much of its moisture and, therefore, retain its structural integrity. Growers should utilize humidity domes, ultrasonic humidifiers or any other device that can keep the humidity between 80 and 100% for the first five to seven days of the cutting process. After the first week, or at the first sign of roots, the cuttings can be slowly acclimatized to their surrounding environment. Nutrient requirements for cuttings are similar to that of seedlings. Most plant varieties require very little fertilizer for the initial cutting stage. High nitrogen fertilizers can actually hinder root development, so diluted blooming fertilizers or specific cutting fertilizers are usually the best choice for growers.
Vegetative stage The majority of fast-growing annual plants have a vegetative stage and a fruiting or flowering stage. Throughout the vegetative stage most plants will thrive in a temperature range of 72 to 85°F. Keeping the temperature consistently within that range during the light cycle will be extremely beneficial. Humidity for the vegetative stage can be much higher than that of the fruiting or flowering stage. The ideal range is usually between 60 and 80%. With the temperature
and humidity consistently kept in the desired range, the plants are able to most efficiently use the light energy, nutrients, CO2 and water supplied by the horticulturalist. When temperatures and humidity fall too far from the desired ranges, the plant’s ability to photosynthesize is compromised, its metabolism slows down and all plant functions are no longer operating at optimal levels. Consistent temperature and humidity in the vegetative stage, teamed with adequate light energy and quality nutrients, results in accelerated, vigorous growth. Nutrient intake for plants in the vegetative stage revolves around nitrogen. A good grow fertilizer will always have a higher ratio of nitrogen relative to potassium and phosphorus. Nitrogen is needed for fast, luscious, green growth. The vegetative stage is the foundation for the future harvest of fruit or flowers and its importance should be recognized as equal to any other stage of growth. The more structurally sound a plant’s vegetative growth, the larger the fruit or flowers it can produce.

Consistency is the key or flowering stage are just slightly lower than that of the vegetative stage—usually around 70 to 80°F, with no more than a 15 degree variance in the light to dark cycle temperatures. The ideal humidity for the fruiting or flowering stage is 40 to 60%, which is significantly lower than that of the vegetative stage. Keeping an indoor garden within these parameters will ensure your fruit or flowers can develop quickly and to maximum size without being impeded by molds or fungus. High temperatures teamed with high humidity in a bloom room are an invitation for a variety of pathogenic molds and a recipe for disaster. Low temperatures in a blooming room will dramatically slow growth and lower yields. Consistency is also important in the temperature difference between the light and dark cycle of a growroom. Repetitive temperature fluctuations that exceed 15°F can create condensation, which raises humidity and increases the likelihood of pathogenic mildews. Nutrient requirements for the blooming stage require a lessened amount of nitrogen in comparison to the other macronutrients. Bloom fertilizers with high phosphorus and potassium are usually the best choice for any fast-growing annual plant. The reduction of nitrogen along with the increase of phosphorus will help trigger plant hormones specific to fruiting or flowering. Once a horticulturist finds the optimal conditions for their given crop, the best way to continually maximize performance is to make those magical parameters as consistent as possible. Consistency allows for the basic plant functions we all take for granted to function at full tilt. Variance from those optimal conditions will slow plant functions down. Our goals as indoor horticulturists are not only to give the plants what they need to survive, but to create an artificial environment in which they can thrive. In order for plants to thrive, they must have their basic needs met—met in a consistent manner on which they can capitalize.

growing for health
by Chad Garbet Nothing is worse than finding pests in your garden or your growroom, and it’s no different when those pests are tiny fungus gnats. 74
Maximum Yield USA | February 2013
Fungus gnats are a common nuisance to many gardeners. This tiny black creature with a slender thorax (much like a miniature mosquito) is annoying when in the area and its larvae eat away at precious root growth, destroying plant structure. Even the smallest amount of fungus can attract them, and infestation can happen quickly—often before most can notice. The larvae—translucent, greyish-white mini worms with black heads—hatch from small grey silk-like cocoons. Any signs of any of these creatures can stress gardeners out, and most people will immediately think of turning to pesticides. Now, that might be a good option, but one should always remember that a pesticide is a poison. So, that being said, pesticides should always be used as a last resort. Luckily, we have other options. There are now natural-based gnat products on the market. Also, as humans have dealt with pests naturally for thousands of years, it is possible to take things into your own hands. Pesticide-free options are almost always an easy fix and, being the busy gardener that I am (like most gardeners), easy sounds like it saves some of that precious time. First, you have to think like the gnat. Be the gnat. Now, that we are gnats: aren’t you kind of hungry? After all, we see that there’s a bunch of hungry gnats out there on our plants, so now we have to figure out what they eat and how to get rid of that. They are called fungus gnats so that saves us some brainstorming. Fungus is the primary food source for gnats. These little buggers are attracted to it like the scourge. Fungus might not even be apparent at the time, but these pests smell it out. Small amounts of fungus are easy enough to clear out. In bad fungus cases, we might want to move directly out of the growroom. For small fungus infestations, an easy solution is baking soda. It’s in most refrigerators, cupboards and pantries, so it saves us a bit of time and
some money. Mix about a level tablespoon of baking soda and a single drop of dish detergent per quarter gallon of water, remembering to shake well. Spray this on your plants lightly about once every three days for about two weeks. The baking soda raises pH, thus causing fungus to stop its growth, and the detergent makes sure the area is clean, thus stopping anymore fungi from forming. Now that the fungus gnat’s main food source is gone, hopefully no more fungus pests will be attracted. After this, the current population’s numbers will start to dwindle down. You might find the few stragglers, but this is okay; home remedies sometimes take time. Now, like Superman, the fungus gnats have a kryptonite. It’s cinnamon. Those little guys can’t stand it. You can see them squirm when you lightly dust the soil with the cinnamon. Also, the same effects are present when you water with chamomile or spearmint teas. (I personally think the cinnamon works the fastest.) Gnats will literally flee the scene, leaving only a few egg sacks. However, you have to be persistent and repeat a few times or they will multiply and come back. After a few weeks of treatment, you will see the fungus gnats are not present. To make sure the little pest’s don’t come back, ensure your garden or growroom is always clean. For heavily effected plants, these home remedies might not work and pesticides might have to be applied. Remember, this is only a last resort; try to do the all-natural ways first. Still, there is another way to get around pesticides and home remedies. Mother Nature provides us with more bugs to fight against the pests. Bugs that eat other bugs… seems pretty neat to me. Nematodes and Hypoaspis miles are two great warriors to use to get revenge on the fungus gnats.

“ it is in the best interest of the gardener to have some idea of the nutritional value of the fertilizer being added.” Plants require nitrogen (N), phosphorus (P) and potassium (K), along with other elements known as macro- and micronutrients, to grow well. In the wild, plants send out roots and try to find usable sources of these elements. In a garden, these nutrients are usually supplied (one way or another) by the gardener via fertilizers. With fertilizers, the gardener adds material that contains the desired elements in forms that are either immediately available to the plant, such as is the case with many nutrient salts, or will break down gradually over time to become available to the plant, as organic materials tend to do. In either case, it is in the

best interest of the gardener to have some idea of the nutritional value of the fertilizer being added, both to make sure that they don’t overfeed or insufficiently feed their plants, and to make sure that they aren’t adding several sources of one element and not enough of another. Nutrient solutions are generally based on true solutions, although the math works out the same even if they are mixtures instead. A solution is made of at least two substances. The majority of the solution will be the solvent (in aqueous solutions, like those used in gardening, the solvent used is water). The substance dissolved into the water is known as the solute. The amount of solute in a solution determines the solution’s concentration. To put it simply,

the more nutrient added to the water, the stronger the solution becomes. Knowing what elements (nutrients) a solute (the fertilizer) has, and at what strength they are in, is important to calculating the final nutrient solution given to the plants. To help with this, fertilizers are marked with an N-P-K listing values to help gardeners get an idea of how much N, P and K is in the bottle or bag. Parts per hundred is a pretty common way to relate two things, although it is more commonly referred to as percent. For example, a fertilizer with an N-P-K rating of 10-5-14, is made of 10 parts N per 100 parts of fertilizer. Another way to express that is to say it is 10% N. In the case of N, the N-P-K value listed and the amount of elemental N are the same. For P and K, their N-P-K values are for the oxide forms. Phosphorus oxide is 43.6 parts per 100 elemental P, so— using the N-P-K value above—multiplying 5 by 0.436 will give the elemental P value of 2.18 parts per hundred, or 2.18%. Potassium oxide is 83% elemental K, so a final N-P-K value of 14 would indicate a fertilizer that is 11.62% K (0.83 x 14 = 11.62). While knowing that the composition of our solute is 10% N, 2.18% P and 11.62% K tells us some useful information about the proportions of what we are putting into the water to make our solution, concentration is another critical factor. As this is a
pretty potent nutrient, the difference between mixing 1 mg per liter and 1 tsp (5 mg) per liter makes for a very different experience for the plants (this is why I recommend at least reading the recommended feeding rates even if you don’t follow them exactly). Just how big of a difference can be shown with a little more math and the numbers we already have. 1 liter of water weighs 1,000 mg. If we add 1 mg of solute, the total weight becomes 1,001 mg. Since our solute is 1 mg of 10% elemental N, we can calculate the weight of the element: 10% of 1 mg = 0.1 mg. Since fertilizers are added to in small amounts, and the amount of the desired elements are only a fraction of those small amounts, it is common to use parts per million (ppm) to express how much of each element is in the nutrient solution. Parts per million is used for concentrations smaller than can be easily expressed in parts per hundred (percent), but larger than those commonly expressed in parts per billion. To calculate ppm, simply divide the weight of element in solute by the total weight of solution and multiply that total by one million. So, using the data from our example for N:
(0.1 mg N / 1,001 mg) x 1,000,000 = 100 ppm elemental N We can also calculate the value of P and K using this same formula.
(0.0218 mg P / 1,001 mg) x 1,000,000 = 22 ppm elemental P (0.1162 mg K / 1,001 mg) x 1,000,000 = 116 ppm elemental K So, if 1 mg of this nutrient is added per liter, the nutrient solution will have 100 ppm N, 22 ppm P and 116 ppm K—which is in the ballpark for many plants that aren’t actively fruiting. Since plants can survive twice those values, going as high as 2 mg per liter would be reasonable to work up to.

“not only can current feeding schedules be analyzed, but they can be adjusted to produce specific ppm solutions for different stages of plant growth.”
Note: if gallons are easier for you to work and mix in, simply multiply the 1 mg by 3.78541 to get the amount to add per gallon (in this case, we would use 3.78541 mg per gallon). Back to our example, if you were to use 1 tsp per liter (or a heaping tablespoon per gallon) instead of 1 mg, calculating ppm shows how dramatic a difference that makes for your plants. Here is the math:
feeding problems. Also note that the equation can be reversed to estimate a dose from a desired ppm. If a concentration of 150 ppm of N is the goal (and we’re using our sample solute of 10% N), then:
150 ppm = 10% x 1,000,000 x amount to add / 1,000 mg (ish) This reduces to:
1 tsp = 5 mg
This will almost certainly cause over-
Weight of N in solute = 0.5 mg (10% of 5 mg)
Weight of P is solute = 0.109 mg (2.18% of 5 mg) Weight of K in solute = 0.581 mg (11.62% of 5 mg) Total weight of solution = 1,005 mg (1,000 mg water + 5 mg solute) So, (0.5 mg / 1,005 mg) x 1,000,000 = 498 ppm of elemental N (0.109 mg / 1,005 mg) x 1,000,000 = 108 ppm of elemental P (0.581 mg / 1,005 mg) x 1,000,000 = 578 ppm of elemental K

Maximum Yield USA | February 2013
150 ppm = 0.1 x 1,000 mg x amount to add Leading to the answer of:
1.5 mg = amount to add One of the most important statistics to consider in formulating a feeding schedule is the ppm of each element of the final solution. By running the numbers on paper, schedules can be evaluated (even if they use several different components in concert). Also, not only can current feeding schedules be analyzed, but they can be adjusted to produce specific ppm solutions for different stages of plant growth. For those that follow the manufacturer’s recommended application schedule, these types of calculations should already have been into account. However, for those gardeners who like to experiment while trying to perfect their own feeding regimen concentrations, these types of calculations can be critical. Oh, and if math isn’t your strong suit, or you would just prefer not to do the calculations yourself, don’t despair! There are free nutrient calculators online that can be used to compute the ppm values with a minimal effort on your part.

Maximum Yield USA | February 2013
As conscious gardeners, we take great pride in the produce that we grow. The main goal in the garden is to cultivate the most delicious, nutritious, high-yielding fruits and flowers possible. Experiencing the bloom stage of a female plant’s life cycle is the fun part of growing that makes hours of tedious labor well worth the effort. It’s the sexy, seductive stage when the plant shows herself in all of her flowering glory. From bashful budding to ripe, busty blooms, the flowering stage is the time in a plant’s life cycle in which it undergoes the most drastic transformation. It is so satisfying—the joyous ending when gardeners get to celebrate the fruits of their labor! As the horticultural industry advances in research and development, specialized fertilizers and supplements have been perfected to give plants the specific nutrients they need to grow into healthy producers. There are hundreds of fertilizers on the market and sometimes deciding which brand to use can be an overwhelming and daunting process. To choose a fertilizer that will produce the best results, it is important to understand the specific nutritional requirements of the crop during the different stages of the flowering process. Experienced gardeners might also choose to use a bloom booster, a potent formula designed to significantly increase the size of the crop’s final yield.

The importance of nutrients The bloom cycle is the stage when plants are focusing all of their energy on producing big, juicy fruits and flowers. Indeed, as plants make the transition from the vegetative cycle to the flowering cycle, their nutritional requirements also change. Specific macronutrients, vitamins, minerals, amino acids, enzymes and trace elements work together in the flowering process to aid in the formation of healthy flowers. Each ingredient in a nutrient mixture plays a different vital role, so making sure that all of the plant’s needs are met can be the biggest challenge for growers.
1,308 words Bloom Boosters Helene Isbell of sunlight down to 12 hours of sunlight per day. In the natural environment, this occurs when autumn arrives and the days begin to shorten and the seasons begin to change. In an indoor garden, growers have the ability to control the seasons with indoor horticultural lighting. By setting the lights on a timer with 12 hours under lights and 12 hours in the dark, the indoor garden mimics the natural cycle of the sun. It sends a message to the plant, triggering the end of its life cycle and forcing it to reproduce. This is the stage in which the plants begin budding. A female plant produces flowers in hope that it will be pollinated by a male plant to produce seeds, which will carry on both parents’ genetics. By preventing male plants from entering the garden space and exposing females to their pollen, gardeners have the ability to create seedless varieties of flowering plants. However, if the plant is exposed to environmental stress, such as light leaks during the flowering process, there is the possibility that it could self-pollinate and produce seeds.

Macronutrients of the flowering cycle
Macronutrients, sometimes referred to as base nutrients, are the primary elements that are the most vital in sustaining healthy plants. Metaphorically speaking, they are the main course in a plant’s meal plan, while micronutrients would make up the side dishes. The three main macronutrients are nitrogen (N), phosphorous (P) and potassium (K) and at least one of these elements are found in all fertilizers. The ratio of those ingredients, known as the N-P-K ratio, represents the proportions of available nutrients by weight in that particular formula. It is delineated on the bottle by numeric values separated by dashes (the first number represents the volume of nitrogen, the second corresponds with the phosphorous and the third with the potassium).

Nitrogen (N): this is the least important macronutrient in the flowering cycle. It encourages photosynthesis and chlorophyll production, aiding in vertical growth
of foliage, and stem and leaf production. Nitrogen is necessary during the vegetative stage, but it should be used very sparingly–or not at all—during the flowering cycle. So, for the bloom cycle, choose nutrients with a low N value on the N-P-K rating. Phosphorous (P): this is an overall beneficial stimulant for flowering plants. It promotes the production of healthy roots and flower sites, as well as plays an important role in respiration, conversion of energy and cell division and growth. Phosphorous also speeds up plant maturity. Potassium (K): this is another important macronutrient during the flowering cycle. It transports liquid throughout the roots and stems of the plant and assists in enzymatic activity. Potassium also regulates fluctuations in plant metabolism, increases the amount of flower sites, fortifies plant growth, heightens the immune system and disease resistance of the plant and aids in overall plant vitality.
The other macros Calcium, magnesium and sulfur are three mineral elements that are categorized as the secondary macronutrients. These elements are generally needed in lower quantities than primary base nutrients.

Calcium (Ca): this plays an important role in cell wall formation and division. Calcium is also a necessary component of the roots, stems, leaves and flowers of a plant. It increases fruit set and promotes beneficial microbial activity. Magnesium (Mg): this element is a key component of chlorophyll. It also increases the availability and efficiency of phosphorous, as well as activates and enables several enzymatic processes. Sulfur (S): this is an important constituent of amino acids. Sulfur also aids enzyme and vitamin development.
Micronutrients Micronutrients, sometimes referred to as trace elements, are other minerals that are vital to plant health. Each plays a specific role in supporting necessary functions in the plant life cycle. They are used in lesser quantities compared to primary and secondary base nutrients (hence, the term micro). The main micronutrients are boron (B), copper (Cu), iron (Fe), chloride (Cl), manganese (Mn), molybdenum (Mo) and zinc (Zn).
What are bloom boosters? Bloom boosters are specialized, multi-functional supplements designed to enhance the natural performance of plants during the flowering cycle. There are dozens upon dozens of bloom boosters to choose from, so considering their N-P-K ratios and specific features highly influences the success that they bring to the garden.

Choosing the best bloom booster While the common goal of bloom boosters is to increase size, density and quality of the final yield, exceptional boosters will also assist with the ripening of the harvest. The boosters that produce the most dramatic results will contain daring levels of phosphorous and potassium. Some might contain vitamin B-1 to assist with shock that plants might experience during the powerful growth rates that result from the booster. To reduce the amount of products you introduce to the nutrient regimen, look for bloom boosters that are versatile enough to use not only as a finishing agent, but also during the first week of flowering to kick-start an aggressive bloom cycle. A well-rounded, clean bloom booster should be compatible with all lines of nutrients, be formulated with food-grade ingredients and be free of dyes and coloring agents. To witness a flowering plant transition through the different phases of its life cycle is nothing short of a miraculous experience. Nature has designed plants to be intuitive creatures; their cycles are triggered by the seasons to precisely perform the functions necessary to ensure their genetic survival. Modern science has allowed humans to perfect the natural process, resulting in yields of unprecedented proportions. With the use of premium-quality nutrients and power-packed bloom boosters, hobby gardeners and farmers worldwide are celebrating exceptional harvests. An expert nutrient schedule combined with the innovative technology continually emerging in the horticulture industry has the unique potential to produce gardens that boast the revolutionary results that will shape the gardens of our future.

Tips to Make Hydroponics Simple Using Foam Propagation Media By Dr. Vijay Rapaka To make hydroponic gardening easy, here are some handy tips on to using foam propagation media from just getting started and propagating unrooted cuttings to germinating seeds and transplanting.
Getting started
Unrooted cutting propagation
The first step is to sterilize all your tools, trays and equipment—really, anything you expect to come into contact with seedlings or cuttings—in order to reduce the risk of disease. Once you’re done cleaning, separate the hydroponic media sheets into strips or individual cells, as crop spacing or your hydroponics system requires. Be sure to space cubes enough to allow proper air circulation and light levels for the specific plant you’re growing. Next, you should fully saturate the media with water, making sure to drain off and dispose of any excess. After sowing your seeds, be sure to keep the media moist. And be sure to use to a new, clean sheet of foam each time you start a new crop in order to maintain a diseasefree environment.
Prior to sticking unrooted cuttings, gardeners should fully saturate the media with fresh water. Once that’s done, place cuttings in the foam’s hole with only enough pressure to seat the cuttings at the bottom. This is typically between a half and three-quarters of the full depth of the cube. Since cuttings have no roots, you must maintain high humidity levels with a humidity dome, spray bottle or mist system. Be sure to keeping the media moist, too. Once you begin to see initial root development, feel free to reduce humidity levels. For the best performance, gardeners should maintain a consistent bottom heat of 75 to 80oF, depending on crop requirements. Then, after plant roots begin to develop, you can begin a more formal fertilization program (adjusting temperature and light levels according to the needs of your specific plant).
94
Maximum Yield USA | February 2013
Seed germination Prior to sowing, make sure you fully saturate the growing media with fresh water. Next, place your pelleted or raw seeds in the cube’s hole. Please note there is no need to cover your seed with any other media. However, you should always keep the media moist during germination. In fact, you maintain a water level of approximately 0.25 in. in the tray, lowering the level as the plant roots develop. For uniform growing results, we suggest maintaining a consistent bottom heat level of 75 to 80oF. Using a humidity dome will aid in germination, but you’ll need to remove the dome as soon as roots begin develop to help reduce the risk of disease. Once germination occurs and the roots start sprouting, you can begin your fertilization program to enhance plant growth. Again, you’ll need to adjust the temperature and lighting according to your specific plant’s needs.
Transplanting
Depending on the crop and the particular hydroponics system you use, you might need to transplant your seedlings or cuttings. If that’s the case, you’ll want to thoroughly water the propagation media prior to transplanting into another media. To determine whether or not your seedlings or cuttings are ready to transplant, simply measure how far the roots protrude from the media. If they stick out 0.25 to 0.50 in. from the media, it’s definitely time to transplant. But rest easy; you don’t need to remove your plants from the foam when transplanting. Just transplant the media along with the plant into its new home. Eliminating the need to remove the plantlet from the foam will prevent root shock or damage and continue to promote healthy plant growth. At this point, you should continue with your regular fertilization program, maintaining the proper temperature and light levels for your specific plant type.

riding the shortwave
Light provides a source of external information to plants, which have a series of photo receptors that sensing parameters such as intensity, direction, photoperiod, spectrum and wavelength. Different parts of the light spectrum can cause different physiological and morphogenetic responses, many of which vary from species to species. This allows growers to use high-tech lighting to tailor the light spectrum towards desirable plant characteristics (while the exact details of the potential of customised wavelength lighting are still being researched and understood, this concept is already well accepted by many indoor gardeners).
Ultraviolet wavelengths While we are aware of the wavelengths that power photosynthesis (blue—450 to 495 nm—and red—629 to 750 nm—light), other wavelengths are sensed by different receptors in plants and might help control normal plant growth and function. Of particular interest these days is ultraviolet (UV) shortwave light. Also known as electromagnetic radiation, this light has a wavelength is shorter than that of visible light but longer than that of X-rays. It is the range 10 to 400 nm. Within this range, UV is divided into a number of band spectrums, including UV-C (below 280 nm), UV-B (280 to 320 nm)
Some studies have reported that other compounds such as beta carotene, which gives the orange color in fruits and vegetables, is also stimulated by UV light.”

and UV-A (320 to 400 nm). UV is a natural part of sunlight and while humans can’t see UV light, some insects and birds can. When we think of UV light most of us are reminded of sun burn, skin damage, genetic mutation and other negative affects; however, small doses of UV are also beneficial for humans as it is responsible for vitamin D synthesis.
When it comes to plants, UV has been known for some time to have harmful effects plants, but in certain plant species, it seems that small doses can have some very beneficial effects (most of which we are only just starting to understand). For example, it’s only recently that it was discovered that plant roots can sense UV-B and use it as a signal between cells, which helps young plants with seedling morphogenesis and normal growth patterns (as with all plants, too much UV light can be toxic, and only small doses are required to activate receptors in plant tissue). Still, this of particular interest for both greenhouse and indoor gardeners—both who have more control of light intensity and wavelength than ever before as they are able to pick and choose from different lamp types and greenhouse films in order to provide varying degrees of UV shortwave light.
UV and protected cultivation When exposed to UV, plants can produce a range of defence proteins that are similar to those activated when a plant is physically damaged. Shortwave light in the UV bands acts as a stress factor on plant growth and is therefore able to induce a wide range of plant growth and developmental characteristics. For example, UV-B light has been shown in a number of studies to
100

reduce plant height and cause the development of smaller, thicker and shorter leaves (a typical stress response in plants). While this type of growth effect might be useful in a number of crops where a short, compact plant form is desirable, such as with potted flowering ornamentals, it might not be an advantage for others. Also, plants can increase their production of these defence proteins as the level of UV light increases up to a point where cell damage starts to become severe. In greenhouse horticulture, there has been the development of a range of cladding films that have incorporated into the polythene material specific spectral filters designed to block or allow through certain wavebands. This finding has an obvious and significant benefit to growers of all crops as a reduction in the use of plant protection chemicals and compounds is a major advantage in commercial production. In contrast, some studies have found certain greenhouse pests (such as whitefly) to be significantly reduced under UV-blocking film claddings. However, at the same time, filtering out all UV might have negative effects on certain aspects of plant growth. Most commercial greenhouse production is still carried out under standard horticultural-grade plastic or glass claddings that block some of the UV wavelengths, allowing other short wavelengths through. In the future, we can
expect to see the development of different greenhouse films for different crops and purposes based on their UV penetration category. One of the most interesting and commercially important findings regarding UV light is the effect on the production of anthocyanin, which gives the deep red pigmentation in red lettuce cultivars and similar colored plants. It has been found that red lettuce (Lollo rosso) grown under greenhouse films that transmit UV light (transparent above 280 nm) had eight times more anthocyanin content, and hence a significantly deeper red color than those grown under UV-blocking greenhouse films. It was also found that total red pigmentation was highest in lettuce when both UV-A and UV-B wavelengths were provided together rather than when just UV-A was provided on its own. Anthocyanin production in many plants has also been found to be stimulated and increased when UV light was supplemented with use of lamps producing short wavelengths in the UV region. Some studies have reported that other compounds such as beta carotene, which gives the orange color in fruits and vegetables, is also stimulated by UV light. Plants produce these antioxidants to protect themselves from the negative effects of shortwave light exposure. For producers of red lettuce and other salad plants where a strong pigmentation is essential for marketability, this is an important finding as the penetration of UV (both as UV-A and UV-B) light down to the crop is likely to be just as essential as the initial selection of highly colored cultivars to maintain anthocyanin levels. As well as increased anthocyanin and plant coloration, exposure to shortwave UV light has been found to

have a range of other benefits. In many species, UV light is an important contributor to flavor and aromatic compounds. Overall higher levels of secondary metabolites are produced under UV and it is thought that when both UV-A and UV-B wavelengths are present, plants accumulate secondary products that protect them from damage to the photosynthetic systems. These secondary metabolites are thought to include UV-protecting or -absorbing compounds that prevent some of the damage to cells and DNA caused by UV radiation reaching the photosynthetic apparatus. This means that the photosynthesis systems are not as damaged as we would expect with exposure to UV radiation. However, in some studies it has been found that damage can still occur to photosystem II in particular under UV wavelengths. In certain species, this causes a reduction in growth; so, it is possible that under UV wavelengths, the plant might divert some of its photosynthetic energy into producing compounds to protect it, thus reducing overall growth slightly. In yet other studies, no significant effect on growth reduction was seen when UV light was provided, so it’s likely any negative effects are species and environment dependant.
These protective secondary metabolites are likely to include flavonoid and phenolic compounds, many of which are also of interest for human health benefits. Anthocyanins, flavonoids and phenolics provide the anti-oxidant activity in fruits and vegetables that are linked to a range of health promoting effects and prevention of degenerative diseases. More recently, the possibility of producing commercial crops with increased beneficial compounds under greenhouse films that transmit sufficient UV has been under investigation.
What does this mean for indoor gardeners? While plants will grow and yield perfectly well under the tried-and-true red and blue spectrums of photosynthetically active radiation (PAR), there does exist the potential to provide specific supplementary short wavelengths where they provide benefits to certain species. Enhancing the deep-red coloration in those plants that require high levels of anthocyanin production—such as red lettuce, ornamentals with highly colored leaves and others grown indoors—would be one such use. Another might be to promote short, stocky, compact plant growth, an advantage in the confined space of an indoor garden where height restriction is a bonus. Increased resistance to pest and disease attack with harder, tougher
plant roots can sense UV-B and use
it as a signal between cells, which helps young plants with seedling morphogenesis and normal growth patterns.”

plants and an activation of the plants’ natural immune response by UV wavelengths could be seen as another major benefit of including some shortwave radiation in the plants’ smorgasbord of light. Many full-spectrum bulbs, fluorescents and other commonly used lamps still provide some UV output, although it pays to check the spectral output to ensure this is in the correct wavelengths of UV-A and UV-B. Despite the potential benefits, the use of UV wavelengths must be considered with some caution: while plants can generate secondary metabolites to protect themselves against low levels of UV, people can’t do the same thing. UV is still an issue with damaging sensitive human skin, so sunscreen protection might be required when working under UV for prolonged periods of time. Also, we need to remember that research studies have shown that both UV-A and UV-B wavelengths should be used together as they have a synergistic effect on plant response. Supplying just some UV-A might give no response and no benefit, while UV-A and UV-B together produce a much greater accumulation of flavonoids and other beneficial compounds. So, while shortwave UV won’t necessarily increase growth, it seems to have certain advantages that can’t be ignored when we consider how complex the interaction of plants and wavelengths actually is.

Vermicompost: Micronutrient Rich Fertilizer From Worms Want to produce your very own homemade organic fertilizer while eliminating waste from landfills? Well, it’s all about the worm poop. There are few friends in the garden more important than the earthworm. Worms increase the permeability of soil, improving drainage and allowing more air and water to penetrate the soil. They eat organic material and the waste they produce, referred to as worm castings, is a micronutrient-rich organic fertilizer. Worm castings are not only rich in the micronutrients our plants crave, but they are full of beneficial bacteria. Now, what if I told you that you could bring the benefits of worms to the indoor garden? What if you could use them to make your own fertilizer loaded with micronutrients and you could do it essentially for free? Too good to be true? Actually, making, maintaining and harvesting your own vermicompost is a really simple process that anyone can learn if they follow a few easy steps.
Making your own worm bin Worm bins are easy to make at home. First, you need a box or bin (plastic storage containers are great for this) to house your worms and the compost. The size of the box depends on the amount of food scraps your family produces; however, the box must be no taller than 12 to 18 in. otherwise the weight of the compost can cause compaction—and if there is not enough air getting to the compost, it won’t be a healthy environment for the worms and millions of beneficial bacteria that are

converting the compost into a great organic fertilizer. To further improve oxygen levels in your worm bin, drill small holes around the sides of your container, roughly 2 to 4 in. above the base. The next step is to line the base of your worm bin with a couple inches of bedding. Bedding will house the worms and can be made from a light organic material—shredded newspaper that has been moistened but not soaked with water makes great worm bin bedding. Once the bedding is in place, you can add the worms. Worms can be purchased at bait shops or dug up in a garden. The worms will work their way down into the bedding instinctively.
Feeding your worms Now that your worms are comfortably set up in your worm bin, it is time to start feeding them. Spread organics loosely over the bedding. Most table scraps are acceptable to add to your worms bin. Fruit and vegetable rinds are great, as well as eggshells and coffee grinds (in small amounts). You can also add lawn clippings, leaves and used napkins and paper towel. Try to avoid adding meat, dairy and fatty foods, mainly due to the odor (especially if your worm bin is indoors). Also, citrus fruits can be a problem if you add too much.
The worms will instinctively move away from the light, to the lowest section of the vermicompost pyramid. Remove the top third of the pile and repeat the process until you have removed most of the compost and most of the worms are left in the bottom. Keep the last bit of compost containing the worms and reintroduce it into your worm bin once you have adding fresh bedding. The little bit of compost will accelerate the breakdown of the next round of organics added to your worm bin. You can now repeat the process of feeding and harvesting year-round.

Harvesting your vermicompost After two to three months, your vermicompost is ready to be added to your indoor or outdoor garden. If you are able to wait four to six months, the organics in your worm bin will resemble healthy soil. To harvest your vermicompost, you need to sort out the worms. One of the easiest ways to do this is to spread the contents of your worm bin on a tarp underneath a light. Try to pile it all into a pyramid shape.

Starting Plants from Cuttings Why would anyone want to go to the trouble to start a plant from a cutting when it is so easy to just go out and buy a small plant at the nursery? Well, think about it: it’s not always so easy to locate that certain plant you want to grow, and it’s even tougher to find it in a healthy condition. And what if you want certain unique characteristics in your specimen? Not every plant with the same genus, species or even same variety will have the same exact traits. Only clones, or cultivars, can guarantee identical characteristics.
“ Only clones, or cultivars, can guarantee identical characteristics.” Grafted clones can be hybridized to produce certain benefits, such as sweetness or health, or to create a new type of fruit. If you’re not so interested in developing some new type of fruit or plant, remember that grafting allows you to produce as many of that awesome tomato plant you had last year as you can. Another reason for wanting to start a new plant from a cutting could include the fact that the original or mother plant doesn’t produce many seeds; a new plant started from a cutting off the old one can produce more seeds. So, let’s get started looking at how we can start a plant from a cutting. The basic process after we have

Starting Plants from Cuttings selected the plant we want to clone involves cutting off a section from the mother plant and getting it to create some roots so we can transplant it. That sounds simple enough, but if we aren’t particular about what time of year, where on the plant we cut, what we cut with and how we plan to get the new roots started, it’s not likely we’ll have easy success. Plants are generally woody or herbaceous. Woody plants have three categories: arborescent (single trunk, such as an ash tree), fruticose (large and woody with many trunks, such as a ligustrum) and suffrutescent (shrubs or vines that are only woody at the base; these are often also considered herbaceous).The suffrutescent group would be the easiest to start from a cutting within the woody grouping. Herbaceous plants are generally the easiest to start from a cutting. These also have three main subgroupings: annuals, which only live for one season

or one year (the celosia is an example); biennials, which complete their life cycle in two years (for example, carrots); and herbaceous perennials, which continue for at least three years (an example would be asparagus). Tomatoes are an interesting case as it they are actually perennials that are cultivated as annuals and are, in my opinion, one of the easiest to start. The best time of year to take a cutting from a plant will depend on what type of plant it is. We want to try to get soft wood or new growth cuttings. The interior cellular walls need to be active and so more easily encouraged to reproduce. For outdoor plants, the odds favor spring. For indoor or hydroponic plants, it will depend more on the plants current life cycle than the time of year. You want the plant specimen to be in top health. No signs of nutrition insufficiency or disease. The plant should also be properly hydrated. Not overwatered or suffering from drought. The cells in the plant tissue will need moisture in order to begin knitting themselves back together and creating the root system you need. Do a thorough inspection of the proposed plant before deciding. Don’t forget to look for insects. Chances are many of the insects that might be on your plant are too small to see without a microscope or at least a good magnifying glass.
Starting Plants from Cuttings
“ Cut back your specimen to just below a node on the stem.” Next, prepare for cutting and restarting. You will need pruners; a razor blade (box cutters provide safety); distilled water; containers for disinfectant, water and rooting hormone; containers with drainage for potting; bleach; soilless potting mix; plastic wrap or plastic bags or a humidity dome; and a pencil or Q-tip (for making soil holes). After selecting a good, healthy specimen, you will need to perform the cutting. You’ll want to prune off your specimen where it grows and then bring it inside where you are set up to do the rest of your starting process. Make sure your pruners are sharp and clean. Cut your specimen from green nonwoody stems near the tip of a branch, not near the base. Once inside the house, you will make your final cuts before restarting. Use a sharp knife for this cut is key as it will reduce trauma and avoid failure. The blade should be cleaned and sterilized. Any bacteria or fungi present on the blade will have a serious negative effect. Wash with soapy water first to remove any dirt or grease, and rinse using distilled water. Dilute the bleach at 10 parts to one, submerse the blade and rinse again. Wipe dry with fresh tissue paper. Now cut back your specimen to just below a node on the stem. Nodes exist where a leaf or petiole was attached. After you make this cut, you will want to remove all but a few leaves with your blade (so keep this in mind when choosing where you cut; the larger the leaf, the fewer needed). The new little root system will need to provide nutrients for the leaves you left on the specimen. Too many leaves are stressful on the new roots and too few will not provide sufficient photosynthesis. Make a final cut on the specimen at the middle of the end node. This is the spot where the plant has the best chance to generate roots. Before planting, wash off the tip in distilled water to assure cleanliness. The amount of time between this final cut and insertion into your prepared potting mix is critical. Be prepared and transplant at once.

Starting Plants from Cuttings While rooting hormone is not always necessary (some plants will even root in water), it does stimulate a plant to generate new roots and can increase your chances of success. Put an adequate amount of hormone into a container (you cannot return the unused hormone to the bag). Dip the new cutting in the water and then into the hormone before putting into the potting mix. Only a moderate amount of hormone should be on the cutting, so tap off any excess. Whether you prefer rooting in water or soil, it will take a week or two before the cutting is ready to transplant. There are pros and cons to rooting in water. While you can see the roots and moisture is always available, some plant types do better with more oxygen available and sometimes transplanting into soil later can be an issue.

Starting Plants from Cuttings
“ Tomatoes are super easy to root and almost assure your success.” If you choose to root in soil, a good quality potting mix is very important. Soil has clay, silt and sand in it and can inhibit tender new roots. A sterile soilless mix with only fine particles is best. After all, you don’t want all your efforts to be wasted because there pests in the soil. Germinating mix is pre-sterilized, but you can sterilize your own in the oven at 180°F for about 30 minutes (just don’t let the temperature go over 200°F). Pre-moisten the soil with your distilled water (avoid using tap water that could contain chlorine), but do not saturate it. The combination of adequate air and moisture is what your fragile little plant needs to develop roots. Use your pencil for making an inch-deep hole in the potting mix—this step reduces any trauma created by pressing the stem into the mix and helps the hormone to stay attached.
120

Keeping the potting mix adequately moist is your next concern. Covering the pot with clear plastic, but allowing enough room for the leaves and making a couple small holes for ventilation, will do the trick. By reducing evaporation like this, you won’t need to be adding more water and risk drowning the plant. The new plant needs UV light but not strong direct sun. After a week or two, you can poke some more holes in the plastic to allow oxygen and drier air to help it adapt. During this period you will need to check and add water. Don’t ever overwater, though; plants need air in the soil as well as moisture. A gentle tug on the plant after a couple weeks will indicate if it has developed roots and is ready for transplanting. Remember that insects love little new plants like this, so even after transplant, you might want to keep it indoors for awhile. Though the process sounds a bit complicated at first reading, it is actually quite easy once you understand it and have tried a couple times. If this is a first time for you, you might want to try a tomato plant. Tomatoes are super easy to root and almost assure your success. Starting a plant from cuttings is a fun new way to take your next step in gardening. Try it, and don’t give up if you don’t succeed at first. The end result is a plant that you will certainly be proud to show your friends.

g n i t n a l p s n Tra s c i n o Aerop from
by Karen Wilkinson
Aeroponics is an innovative growing method that makes optimal use of its airmist environment. There is no growing medium; instead, plants are grown in a closed or semi-closed environment where its roots and lower stem are sprayed with a nutrient-water solution. The roots never stand in stagnant water and constantly receive oxygenated water, thanks to the mist cycle. Aeroponically grown plants are also fast to respond to nutrients, as there is no medium between its roots and food. They can grow bigger and badder than if grown in soil or other media—and due to the direct nature of aero, they have limitless growth potential. To go down the cheesy lane, the sky’s the limit with aero!

Transplanting is by far one of the most critical stages of a plant’s life—after cloning—and it requires much care and preparation, along with patience and a gentle touch. (Just like the stress people feel when moving from one home or office to another, plants feel similar moving pains.) When taken from an aeroponics system to another grow medium, plants are at higher risk of getting broken roots, so handle them delicately. Also, try to limit the number of transplants, and if going into a container, choose one that is large enough for its roots to spread and live a long time. While there are many, some are more popular than others. We compiled a list of five growing mediums and detailed the benefits and potential drawbacks of each.
To aeroponics A simple and smooth transition for the plants, aero-to-aero is the least messy transplanting method (though aero is arguable one of the most challenging grow methods). For the plants, there is virtually no transplant shock; with proper, plant-specific nutrients, they shouldn’t notice a thing.
To coconut fiber A truly organic growing medium that’s gaining popularity in the grow world, coconut fiber can be used in soil and hydroponic gardening systems; some growers also mix it with perlite or expanded clay for increased drainage.
To expanded clay A wildly popular and simple hydroponic growing medium, expanded clay is lightweight and nearly inert, meaning it’s pH neutral and releases virtually no minerals into the nutrient stream. Due to its incredible ability to hold oxygen and nutrients, expended clay is an ideal growing medium for rooted clones and mother plants. Next to soil, it’s the most versatile growing medium.
To soil One of the more forgiving growing mediums, soil is ideal for transplanting to if you want to grow outdoors and enjoy the pleasures of a little dirt.
To rockwool cubes Rockwool is comprised of spun rock and sand, allowing it to retain great amounts of water. It also comes in many shapes and sizes, and holds onto air—which is prefect for newly transplanted clones’ vulnerable roots. Like with most growing methods and techniques, there is no one right way, as it’s all up to the grower’s preference. So, do what works best for you and don’t be afraid of a little experimentation— it could end up increasing your plants’ yield and prove to be a great learning experience!

Interpreting a Water Report
Alkalinity Think of this as the ability of water to neutralize acid. The higher the alkalinity, the more acid it will take to lower the pH of the water. Alkalinity is a measurement that incorporates the amount of bicarbonates, carbonates and hydroxides joined to calcium, magnesium and sodium. Alkalinity is expressed in parts per million (ppm) of calcium carbonate (CaCO3). • Anything above 120 ppm CaCO3 could cause a gradual increase in the pH of your potting medium • Low-alkalinity water (less than 60 ppm CaCO3) is not able to neutralize sufficient amounts of acid. As such, the recurrent use of acidic fertilizers might result in a decrease in the pH of your growing medium
Electrical conductivity (EC) This is a measure of the conductivity of a solution. As the level of mineral salt dissolved in the water increases, so does the solution’s conductivity. EC is often expressed in reciprocal ohms (mhos). Most water reports express EC in millimhos per centimeter (mmhos/cm). • Acceptable range is 0.5 to 0.75 mmhos/cm • Problematic range is 0.76 to 3.0 mmhos/cm • The severity of the problem will be determined by two factors: which compound is responsible for the elevated EC and how high the EC is
Sodium absorption ratio (SAR) This is a measure of the suitability of water for use in agricultural irrigation. It defines the sodium (Na) hazard by comparing the concentration of Na to the concentration of
So, before you sits a water quality report and you’re asking yourself, “Now what?” It says you have a pH of 6.84 and an alkalinity of 37.3… is that good or bad? Well, read on my friends as we delve deeper into deciphering a water report.
pH Potential of hydrogen. This is the measure of the concentration of hydrogen ions (H+). pH is measured on a logarithmic scale of 1 to 14, with 1 being most acidic and 14 being most alkaline. • Acceptable range is 6.5 to 8.0 • pH values under 6.0 and over 8.0 can cause severe problems • pH influences the availability of plant nutrients and other elements.

Interpreting a Water Report calcium (Ca) and magnesium (Mg). A high SAR value can cause reduced porosity in soils and create a salt crust on the surface, which will prevent water from being absorbed by the soil. Fine soils (i.e. clays) are affected more than large particle soils (i.e. sandy soils.) • Acceptable range is less than 10 mEq/L(mEq/l is short for milliequivalents per liter) • Problematic range is 10.1 to 18 mEq/L • Severe problem range over 18 mEq/L
Phosphate (PO4-3)
Commonly found in groundwater and fertilizers. Too many phosphates can cause algal blooms in runoff water, followed by significant decrease in dissolved oxygen. You can manage these levels with reverse osmosis filters or build fertilizer programs around the levels in your water supply. • Acceptable range is less than 1.2 ppm • Problematic range is 1.2 to 2.4 ppm • Severe problem range is over 2.4 ppm
Too many phosphates can cause algal blooms in runoff water.
Potassium (K+)
Calcium (Ca+2)
Potassium (K) originates from dissolved rock, soil and fertilizer. High levels in the solution can increase K levels in plant tissue, thereby creating nutrient antagonism of N or Mg. You can also manage these levels with reverse osmosis filters • Acceptable range is less than 20 ppm • Problematic range is 20 to 50 ppm • Severe problem range is over 50 ppm (can cause foliar damage)
This originates from dissolved rock, limestone, gypsum, soil or fertilizer. High levels of Ca form lime deposits when combined with CO3 or HCO3. • Acceptable range is less than 25 ppm for soil and water hazard, and less than 60 ppm for ideal foliar levels • Problematic range is 25 to 250 ppm for soil and water hazard, and 60 to 100 ppm for problems with foliar injury • Severe problem range is over 250 ppm for soil and water hazard, and over 100 ppm for severe foliar injury
Magnesium (Mg+2) Magnesium originates from dissolved rock, limestone, dolomite, soils, and fertilizers. High levels of Mg form lime deposits when combined with CO3 or HCO3. • Acceptable range is less than 20 ppm • Problematic range is 20 to 40 ppm • Severe problem range is over 40 ppm *Note: When designing a fertilizer program, remember the ideal ratio of K:Ca:Mg is 4:2:1.
Zinc (Zn) Occurs naturally in small amounts. • Acceptable range is less than 2.0 ppm • Problematic range is greater than 2.0 ppm

tips and tricks
Is it
Dead? by Heather Rhoades
How to tell if a plant is dead and how to recover it if it’s only almost dead. How do you tell if a plant is dead? While this might seem like an easy question to answer, the truth is that telling if a plant is truly dead can often be a difficult task. If your plant has lost all of its leaves or the leaves have all gone brown, don’t panic. If you suspect your plant is dead, but you are not sure, the fastest way to tell if it is dead is to check the stems. The stems of the plant should be pliable and firm and will have a green cast on the inside if they are still alive. If the stem is mushy or brittle, check the roots for the same conditions. The roots too should be pliable but firm. If both the stems and roots are brittle or mushy, the plant is dead and you will simply need to start over.
Is the plant really worth saving? If your plant is not dead, the next step is to decide if you really want to make the effort of nursing the plant back to health. Keep in mind that a plant might still die despite your best efforts. Also, the plant will look utterly pathetic for weeks, month or even years. Is it worth spending the time to recover what might be a lost cause, or could you get a comparable but healthy plant at the local nursery or store for a reasonable price? If this is a plant that has sentimental value or is hard to find, then it is certainly worth saving; otherwise, you should just start over again.
132
Maximum Yield USA | February 2013
What to do when only the roots are still alive? If the roots are still good, but the stems are dead, you will be hoping that the plant re-grows from the roots. Cut away the stems a third at a time. You might find that as you get closer to the roots, parts of the stem might be alive. If you do find living stem, try to leave as much as possible. If you find no living stem, leave 2 in. of the stem intact above the soil. Place the plant in conditions where it will get roughly half the amount of sun that is normally recommended for that plant. Water only when the soil is dry to the touch. If the plant is able to, you will see new stems sprout from around the remaining stem in a month or two. If you do not, recheck the roots to see if the plant has died.
What to do when the stems are still alive? Trim away as much dead stem as you can find on the plant. Place the plant in indirect light or in conditions where it will get roughly half the amount of sun that is normally recommended for that plant. Water only when the soil is dry to the touch, but do not let the soil dry out completely. In three to four weeks, maybe less, you will hopefully start to see new stems or leaves being produced where the old leaves were. As the leaves and stem become more fully developed, cut away any parts of the stems that are not producing leaves or stems. If you do not see any new leaves or stems after a few weeks, recheck the stems on the plant and prune away the dead wood as the stem dies. Remember, even with all the love and attention in the world, it is sometimes not possible to save a badly damaged plant. Sometimes you just have to start over and try not to let what happened before happen again.

Organic Fertilizer Elemental Content:
Why It's Important by J. Benton Jones, Jr.
Knowing the elemental content of your organic fertilizer is imperative to plant health. However, as J. Benton Jones, Jr. points out, this information isn’t as easy to discover as one would think…
136
Maximum Yield USA | February 2013
Organic Fertilizer Elemental content A colleague who owns both a couple hydroponic stores called me with an inquiry. He and his customers had tried to wade through the current maze of organic fertilizer products in order to make a selection that would meet the elemental requirements of the plant species that they were growing. They didn’t know what to do. State statutes that regulate the labeling and sale of materials as fertilizer do not fit those substances that are identified as containing organically-sourced essential plant nutrient elements. A material marketed as fertilizer, in terms of its elemental content, requires an analysis that identifies its percent content. For nitrogen (N), the amount on the label is the elemental total; for the element phosphorus (P), the number represents the citrate-soluble form (expressed as the oxide, P2O5); and for potassium (K), it is the water-soluble form (expressed as the oxide, K2O). The other essential plant nutrient elements, if guaranteed, are identified as their elemental total content, although some might use their oxide form. However, labeling is not the primary concern for the user; when using an organic fertilizer as a source for a particular element, it is the accompanying elements—identified or not—that can result in an elemental insufficiency. A recent correspondent asked me about various organicbased sources for N, in particular wondering if blood meal would be suitable (it has relatively high N content).
“ when using an organic fertilizer as a source for a particular element, it is the accompanying elements— identified or not—that can result in an elemental insufficiency.”
138
Maximum Yield USA | February 2013
Organic Fertilizer Elemental content I responded with another question: What about the companion elements? In blood meal, P has been reported to be as high as 1.0% (2.2% P2O5), depending on the blood source. With repeated use of blood meal as an N source, the accumulating P could eventually result in an excess that could adversely impact plant growth. I was sent a sample of a blood meal material that had excellent physical properties, finding that its N content was 14.0%, the high end of that reported in the literature. Another blood meal product I saw listed only N (at 12.0%). This range in N content raises an interesting question: what is the expected natural range in N content among blood meal products? It might seem like an inconsequential question, but could have significant importance if blood meal is the only available N source. The other element of interest would be P, reported to be 1.0% in some literature, but was found to be 0.6% in the sample that I assayed. I decided to purchase a package of blood meal from a local fertilizer store for analysis. The results of the two blood meal products are given in Table 1. When I was preparing the samples for elemental analysis, I found that blood meal product A went into solution when concentrated nitric acid was added to the digestion flask, while blood meal product B did not. The physical form of the blood meal product A is a small pill, while blood meal product B was a mix of fine and small particles of varying size. Would the differences in solubility and particle characteristics have an effect on the reactivity of blood meal when added to a rooting medium? It’s a question that needs to be determined by testing.
140
Maximum Yield USA | February 2013
The differences in elemental content between in the two blood meal products is considerable (see Table 1), and many of the element contents are not in agreement with values found in the literature for blood meal (N higher, P and K lower). So, the next question is: what would be the range in elemental content among batches of the same blood meal product, as well as between different blood meal sources? For a grower assuming that the blood meal product being using has a 12% N content, what plant growth effect would occur if the actual product contains 16.6% N? The other element in blood meal that can affect a plant’s physiology is iron (Fe). Depending on the growing conditions and method of use, high Fe availability can interfere with zinc (Zn) metabolism in the plant by inducing a Zn deficiency (a deficiency that might not be visually evident, but will result in reduced plant growth). The elements in an organic fertilizer are not in that form required for root absorption, therefore requiring
“ Depending on the growing conditions and method of use, high iron availability can interfere with zinc metabolism in the plant.”
Organic Fertilizer Elemental content decomposition of the organic matrix. Such decomposition might not readily occur and, in addition, decomposition might then result in either the transformation of an element into another form not available for root absorption, or be absorbed by the micro-organisms present in the rooting media. Those organisms that carry out decomposition are also plant-like, having the same elemental requirements as the green-leaf plant growing in the rooting medium. Since these organisms are strong competitors, they are in position to absorb released elements and thereby deprive the plant. A good example is what occurs when a highly carbonaceous substance is added to a soil, as the growing plant might become N deficient as the organisms in the rooting medium absorb whatever N is available in order to decompose the added material, thereby depriving the plant of N.
“ There are three physical phases within a rooting medium: organic, inorganic and a solution phase.”

Organic Fertilizer Elemental content
“ plants do not grow well when an active biological environment exists within a rooting medium.” There are three physical phases within a rooting medium: organic, inorganic and a solution phase. The factors that will determine which equilibrium exists within the solution phase are determined by the physical and chemical characteristics of the mineral and organic components, plus the factors of temperature, moisture level and pH. With the addition of an organic substance to a rooting medium, a dynamic and ever-changing environment will evolve, which could significantly alter the biochemical activity within the rooting media. However, plants do not grow well when an active biological environment exists within a rooting medium. Such activity consumes oxygen and interferes with the movement of ions within the water solution that surrounds plant roots. When an element is not sufficient in the rooting medium, the trick is to apply only what is required by the plant, adding either an inorganic or organic fertilizer source of that element. In order to do so, three things need to be known: 1. The nutrient element requirement of the plant. 2. The available concentration of that nutrient element already existing in the rooting medium. 3. The quantity of nutrient element being supplied by the applied inorganic or organic fertilizer. For most inorganic fertilizers, the elemental content is usually known for all the elements in the fertilizer. For most organic fertilizers, on the other hand, the primary element content is known and the accompanying elements are not. For the user, this can result in an elemental insufficiency of a companion element when using an organic fertilizer. The remedy: have the organic fertilizer assayed for its elemental constituents. 144

We spent close to a month traveling the countryside, procuring and learning, and we collected and returned to the United States with more than 200 strains. One of these strains eventually became ExHale. When producing mushrooms, your goal is to find a strain that produces mushrooms easily and consistently. When looking at a strain for CO2 production, the reverse is true. A strain that is non-fruiting will produce more CO2 for a longer period of time. After a strain actually produces a fruiting body, CO2 production falls off as vigor drops. The mycelium

The amount of CO2 produced by each strain was also tested. After a long and vigorous process, we focused in on one strain that we believed held great promise. Through a process of tissue

transfers from petri dish to petri dish, we subcultured this strain a number of times. With a trained eye, you can notice desirable characteristics and selectively transfer this thread of mycelium into a new plate insuring that characteristic is preserved. The ExHale strain is now stored in a number of strain vaults that we operate here at the farm, as well as off-site locations—one of which stores the strain cryogenically at -70°F. When working with mycelial cultures, we must continually be

The mycelial cultures for ExHale begin their life inside a petri dish, where the substrate is potato dextrose agar. Once the mycelium has colonized the plate, it’s time to move to a more nutritious substrate. Cereal grains are the perfect choice for the second phase of mycelial growth. The substrate is autoclaved at 250°F for one hour to insure sterilization. There are many choices of grain, but most use rye, wheat or millet. Mycelium is transferred to the cereal grains and allowed to grow out completely.

Once this second phase is complete, we begin to prepare the final substrate for the purpose of CO2 production. We have developed techniques here that are on the cutting edge. Our scientific discoveries have been published in scientific journals and presented at scientific conferences worldwide. The science lies in the carbon-nitrogen ratio (or, C-N ratio). Most mushroom producers pay little attention to this; however, it might be the single most important factor when it comes to a good substrate. The ExHale substrate is fortified with more nutrients than normal mushroom substrates, which allows for more CO2 production over a longer period of time. The substrate

is blended and water is added to achieve a moisture content of around 65%. After blending, the substrate is placed into a heat-tolerant bag prior to being autoclaved. This bag contains a microporous breather patch that will allow the bag to breathe after it is inoculated. Once sterilized, the bags are allowed to cool in a HEPA-filtered environment to maintain sterility. Once cooled, the bags are inoculated with the ExHale strain and the bag is sealed using a high-heat continuous belt sealer. The bags are pressure tested to insure a good seal and allowed to sit in our incubation room while the mycelium recovers from the transfer. After a few days, mycelial growth is evident and it is now time to label and date each bag. Each bag receives a replace-by date and is packed and is now ready to ship. ExHale is made to order, we ship within one week of inoculation. We ship to a number of stores direct, as well as utilizing a number of distributors. Within the next few weeks the color of the bag changes from the brown color of the substrate to the whitish color of the mycelium. This white color means optimum CO2 production. ExHale was created with the grower in mind. We are here to help those in our industry succeed. ExHale was created by farmers for farmers. We believe that customer service is key. They say the customer is right; well, our motto is “If the end-user of our product is not happy, then we are not happy.” We welcome calls from anyone who has questions or concerns about the ExHale bag. When you call us, you talk to someone who cares about your concerns. That is just the way we operate. So, the next time you see an ExHale CO2 bag, you will know a little bit more about us and know a little bit more about how it’s made. Maximum Yield USA | February 2013

Balance In
Wat er & So i l
Balance has a number of different meanings when it comes to your system’s water, nutrient solution and soil. One example is the cation-anion balance, which refers to the system’s total electrical charge. Here’s how it works…

According
Cation-anion balance of a given system is calculated by comparing the total charge of the positive-charged ions (cations) with the total charge of the negative-charged ions (anions).
Calculating the cation-anion balance
to the principle of electroneutrality, the total charge of an aqueous solution must be zero.”
In order to find the amount of charges, we have to use a unit that integrates both the concentration (and mass) of the ion and its charge. This unit is called the equivalent (we also use the milliequivalent (meq), which is 1/1,000 of an equivalent). The equivalent is calculated simply by multiplying the number of moles of the ion by its charge. For example, the molecular weight of calcium is 40 lbm/ lbmol and it carries a positive charge of +2 (Ca+2). Therefore: 40 lbm of calcium = 1 mole x 2 = 2 equivalents. As another example, the molecular weight of nitrate (NO3-) is 62 lbm/lbmol and it carries a negative charge of (-1), hence 62 lbs of NO3- = 1 mole = 1 equivalent. Cation-anion balance is calculated by comparing the number of equivalents of the cations with the number of equivalents the anions.
analysis is not accurate. Also, if the laboratory did not test for one of the major cations or anions, then a correct balance cannot be calculated.
Cation-anion balance in nutrient solutions
All nutrient solutions are always balanced in respect to the cation-anion balance. For example, a typical analysis of calcium nitrate is:
14.4% N-NO31.1% N-NH4+ 19% Ca+2 • Converting to milliequivalents results in:
1.03 meq NO3 0.08 meq NH4 0.95 meq Ca • Calculate and compare the cations and anions:
Is your irrigation water balanced? When ionic compounds—minerals, salts and fertilizers—dissolve in water, they are dissociated into ions. According to the principle of electroneutrality, the total charge of an aqueous solution must be zero. Therefore, the number of positive charges must be equal to the number of negative charges. This implies that the irrigation water is always balanced. So, if water is always balanced, why do we check the cation-anion balance for? The purpose of checking the cation-anion balance in a water analysis is to validate the water test results. If the analysis is accurate, then the sum of milliequivalents of cations and anions should be nearly equal. However, an error of more than 5% in the cation-anion balance might imply that the
Cations (NH4+, Ca+2): 0.08 + 0.95 = 1.03 Anions (NO3-): 1.03
As we can see, it is balanced. This same principle applies to all mineral fertilizers. Therefore, addition of mineral fertilizers to the irrigation water always results in a balanced nutrient solution. Also note that there is a difference between a balanced nutrient solution

Cation-Anion Balance in Water and soil
and a cation-anion balanced solution. The first refers to the ratios, proportions and concentrations of the substances in the water. For example, we might require specific ratios between ammonium and nitrate in the solution, and we might also require minimum concentrations of certain substances and maximum concentrations of others. Therefore, a nutrient solution that is considered to be balanced for a certain crop might not be balanced for another crop; however, it will be always balanced with respect to cation-anion balance.
Is your soil balanced?
Soil is composed of two phases that are relevant to this discussion: the liquid phase and the soil phase. The liquid phase is the soil solution, and being an aqueous solution, the explanations above are valid for this phase (i.e. cations and ions are balanced). The solid phase, on the other hand, is composed of the soil minerals. As in the case of the nutrient solution, a balanced soil does not refer to the cation-anion balance, but to
the ratios between the substances in the soil or their quantity in each of its phases. In regards to cation-anion balance, most soil minerals have a negative charge on their surfaces. So, in order to neutralize this charge, cations are adsorbed to these surfaces. These cations are called exchangeable cations as they are in equilibrium with the soil solution. As such, a soil system is also always naturally balanced in the cation-anion sense. Also, there are different types of balances and different approaches to determine them. For example, when the balance refers to the ratios between the exchangeable cations (K+, Ca+2, Mg+2, Na+), then it is called base-cation saturation ratio. So, is your system balanced? The answer to this question depends on the approach you want to take for interpreting your test results and on the crop you are growing. However, as you can probably guess by now that if we referring to the cation-anion balance, the answer to this question would be yes, always.

10 facts on...COPPER by Philip mcintosh
COPPER Copper (from the latin cuprum), atomic symbol Cu and atomic number 29, is a soft, reddish-pink- to orange-colored metal.
Cu
It was discovered to be essential to the normal growth and development of higher plants in 1931. Copper is required by plants in very small amounts. It doesn’t take much to get the job done. About 2 to 10 ppm of Cu is typically found in dried plant matter. So what exactly is copper’s job in a plant? Copper is part of the electron transport system and serves as an enzyme activator. Most of it is found in chloroplasts. Copper is often provided in nutrient solutions in low concentrations of 0.001 to 0.01 ppm as Cu+2 derived from copper sulfate (CuSO4•5H2O). The Cu+1 ion is called the cuprous ion and Cu+2 is called the cupric ion. The Cu concentration of feed water should be checked because there might be enough present to meet a plant’s needs, especially if the water travels through a lot of copper pipe. Too much Cu is bad. If the Cu concentration in the nutrient solution gets too high (say above 0.1 ppm), it can damage roots. But, not enough Cu is bad too. The symptoms of Cu deficiency include chlorosis (loss of chlorophyll) in older leaves, stunted growth and malformed fruit.

Mastering the Art of Hydroponics (STEM) by Ryan M. Taylor
MAKING a Natural PLANT GROWTH
Regulator CHEAPLY
Plant growth regulators are making a buzz in the hydroponics industry lately, and one of the reasons is because they’re so darn expensive. Here’s how to make your own—it’s simpler than it sounds!
152
Maximum Yield USA | February 2013
The hydroponics industry has been abuzz in recent months with discussions concerning plant growth regulators (PGRs), hormones that are used ubiquitously in the horticulture industry. These products are used throughout the lifecycle of plants, whether we are using auxins to produce rooted cuttings or paclobutrazol to retard the vertical growth of plants. Most of the conversations I have participated in recently have revolved around one of three dimensions: the use and safety of these products, whether it is better to use natural or synthetic hormones and why these products are so expensive to purchase. Any one of these topics would necessitate many more column inches than are available here, so I will primarily focus on a single topic that has ramifications across the aforementioned dimensions: making a natural plant growth regulator cheaply. From the outset, I should make my personal philosophy clear: I advocate using plant growth regulators to efficiently optimize plant growth, regardless of whether they are derived with natural methods or synthetically created. Since I run my own hydroponic horticulture business and keep a vigilant eye on my cost structure and profit margins, I generally choose to create my own PGRs naturally than to buy them. While this might sound daunting, the technique I will describe hereafter provides cost savings across the board for interested growers. The basic method can be summarized as follows: recirculate your nutrient solution for an extended period of time (e.g. beyond one year) to allow organic compounds exuded from the roots, including PGRs, to accumulate in the nutrient solution. So, rather than periodically discard-
Using a continuous system, the lettuce was physically smaller, but the yield was not.
ing your complete solution, you should simply top-off your solution with pure water or a diluted-nutrient solution as necessary to maintain a set electrical conductivity level. As the continuously-recirculated solution builds up natural PGRs, your canopy size per plant will decrease—but your plants will mature at a faster rate. To maximize this growth strategy, it is recommended that you adopt a continuous production system rather than a batch production strategy. This might sound too simplistic to work, but I assure you that the science is sound. After reading some technical briefs from NASA, where a team of researchers grew potatoes with the nutrient film technique for over a year without changing the nutrient solution, I attempted this with my own crops. I grew three types of lettuce in floodand-drain tubes for a year without completely changing the nutrient solution and was amazed at the differences between the early plantings and those near the end. As you can see from the pictures, the plants became smaller over time, but I didn’t lose yield over time. It amazes me that I could save so much money on nutrient solution and growth regulators by growing my own PGRs so to speak; however, the major trade off is that a lot more planning and effort is needed to rationally manage your nutrient solution parameters. In any event, you can be sure that your PGRs are naturally produced and are appropriate for the crops you are growing. Maximum Yield USA | February 2013

Did you know it’s possible to grow outof-season raspberries in both warm and cool climates? Did you also know that it’s best to grow these berries indoors, no matter the climate? Well, now you do, and here’s how to do it… Since raspberries do not travel well, they are an ideal crop to grow for the local market. While it is possible to grow out-of-season production of raspberries outside in warm climates, it is favorable to grow them under some form of protective cultivation because the fruit is larger (due to shelter from wind and rain) and birds can be excluded. Size is an important aspect of all berry fruit production, and raspberries are no exception. In most developed countries, harvesting costs are high due to high labor costs; so, the larger the fruit, the more pounds of fruit can be harvested per hour. Also, consumers in general prefer large over small berry fruit. When I was an undergraduate student in the mid1950s, one of the postgraduates was Ian (later, Dr.) Williams, whose research work on raspberry physiology set the basis for the year-round production of raspberries. He demonstrated that there are essentially two types of flowering patterns for raspberries: the autumn flowering types, which produce flowers
on the tips of the young canes (primocanes), and the summer flowering types, which only produce flowers on the lateral buds of the one-year-old canes (florocanes). Of course, the autumn flowering types will also produce flowers on the lateral buds of the young cane after going through the normal winter dormancy. Thus, in theory, it should possible in theory to produce ripe raspberries at any time of the year by using the appropriate environmental treatments. I first came across this in the mid-1990s when I visited a berry fruit grower who was growing both strawberries and raspberries out of season. The methodology for the raspberries was simple in the extreme. Autumn flowering raspberries were grown outside in pots and the pots were transferred into a greenhouse once the fruit had set. The result was a crop of good-quality raspberries, which matured after the normal outdoor autumn crop had finished (or been damaged by the weather). Once the crop was finished, the pots were put outside, where the canes experienced the essential winter chill to break dormancy. In February, the fruiting tips of the canes were removed and the pots were returned to the greenhouse, where they produced an early crop of raspberries on the florocanes. The pots were then moved outside, the old canes were removed and the young canes were allowed to grow and produce new primocanes. This provides a continuous supply of raspberries year-round, and in order to achieve this, one needs to make use of both florocanes and primocanes in a more distinct way.

Raspberries have a very simple means of vegetative propagation, which was developed by Professor Hudson in the early ’50s. If dormant raspberry roots are cool stored then the dormant buds on them will shoot to produce young canes when they are put into warm, moist growing conditions. If the cultivars are ones that flower on the young wood (primocane types), then it is very simple to establish a new lot of planting material. The downside is that when growing from root cuttings, the young shoots are juvenile and do not initiate any flower buds on the lower nodes. However, this should not be a major concern because we have is the potential to produce primocanes at any time of the year without the need for large cool storage resources as the roots take up very little room (they would, of course, be sealed in plastic bags while in the cool store to reduce moisture loss). This is a technology I suspect can be undertaken anywhere in the world, provided field temperatures are not too extreme. Since florocanes are the one-year-old primocanes, they need not be autumn flowering types. One common method of producing early raspberries in protective cultivation is to grow the canes in a cool climate where the autumn temperatures cause early dormancy and then to transfer the canes to a warmer climate once they have experienced enough winter chill
to ensure good bud break. This winter chilling can be natural or it can be simply managed by transferring the canes into a cool store at the appropriate temperature (44.6°F) for the correct amount of time. This, however, will be cultivar dependent; bare-rooted canes need to have their roots protected from moisture loss while in the cool store. In fact, the best results are obtained when using potted plants. The system is called the long-cane system. Also, as we are talking of a high-value horticultural crop, it is essential that the plants are grown in a highquality growing medium with the appropriate supply of moisture and nutrients. Coir (coco peat) is a very suitable medium, and using large pots (or coir modules) with drip fertigation is the most logical solution. Pollination is essential, and bumble bees are the obvious method for out-of-season production. It goes without saying that attention should also be taken to ensure good pest and disease management.

Woody plants have three categories: arborescent, fruticose and suffrutescent.
The main use of phosphorus in plants is for the formation of adenosine triphosphate (ATP), the energy-storing molecule of the plant. Phosphorus is also used heavily in root growth and other biochemical processes.

Bloom boosters that produce the most dramatic results will contain daring levels of phosphorous and potassium. Some might contain vitamin B-1 to assist with shock that plants might experience during the powerful growth rates that result from the booster.
The elements in an organic fertilizer are not in that form required for root absorption, therefore requiring decomposition of the organic matrix.
The N-P-K value listed on a fertilizer label is the same as the amount of elemental nitrogen in the fertilizer. The label value for phosphorus and potassium, on the other hand, are for those elements’ oxide forms.

Ultraviolet (UV) shortwave light (10 to 400 nm), also known as electromagnetic radiation, has a wavelength that is shorter than that of visible light but longer than that of X-rays. Within this range, UV is divided into a number of band spectrums, including UV-C (below 280 nm), UV-B (280 to 320 nm) and UV-A (320 to 400nm).
During germination, the majority of summer plant varieties require warm conditions (usually 72 to 80°F). Spring or fall varieties of flowers or vegetables, however, require lower temperatures for germination.
Alkalinity is a measurement that incorporates the amount of bicarbonates, carbonates and hydroxides joined to calcium, magnesium and sodium.
Phosphate fertilizers are used in large amounts in horticultural, agricultural and turf applications and they are often blamed for algae blooms that suck oxygen from rivers and lakes, thus resulting in large fish kills.
