SIMON SAYS What is a good disinfectant to clean out hydroponic units that can be used while growing a crop? Thanks, John

There are many more people inoculating hydroponic systems with various microbe armies in today’s high-tech gardening environment. This is tempered by those people that feel the best way to run a hydroponic system is with zero tolerance to life forms, taking hydroponics back to its sterile roots. There is definitely a case to be made in both circumstances. Since your question relates to the disinfecting approach, let’s start there. Remember that whichever approach you take, having a

Maximum Yield USA | September 2011

clean growing area is the key to success; dirty spaces and equipment will always develop more problems than clean and organized spaces. When choosing the disinfecting route, there are a couple of options that can be useful while actively growing. An option that is popular with growers is the use of hydrogen peroxide. Hydrogen peroxide can act as a disinfectant as it disassociates into water and free oxygen. This disinfecting effect will be temporary and may only last a few hours. Be cautious when using this substance, especially when diluting high concentrations in water. A better option would be a type of continuous disinfection, rather than a staggered application of hydrogen peroxide. If you are concerned about water contaminants you might want to consider installing an inline UV sterilizing system placed between the reservoir and the hydroponic units. A small bulb blasts the water with UV light as it passes through the filter. As long as this type of unit is well maintained, it will virtually eliminate all biological issues within your water supply. Whether you are culturing helpful biology or banishing all biology, in both situations you want to be sure to focus on dissolved oxygen levels since most pathogenic organisms thrive in low oxygen environments. This is directly related to water circulation and temperature so ensuring water movement and low temperatures will both help dissolved oxygen. Also consider the use of supplemental oxygen supply ranging in sophistication from air pumps to electrolysis systems.

Something that more gardeners are attempting is to bring specific biology into their system. The concept behind this is to inoculate with beneficial organisms that will displace or out-compete undesirable ones. This is a delicate process that is gaining more traction, and for good reason; it can be very effective. There are a variety of bacterial and fungal-based products available in the market. These organisms are generally quite aggressive and will form what is called a biofilm on roots, thereby protecting the plants, essentially creating a perimeter shield. These organisms secrete all sorts of substances that can do much more that protect your plant. Check with your local shop to learn more about biological inoculants. Part of what makes organisms effective is their release of enzymes, which break down unwanted material. It is also possible to take advantage of enzyme-based products, which will do a great job cleaning up a system without adding biology into your set-up. There are several quality options so research this opportunity if you don’t want to look at a living army in your water. Above all else, remember to take the time to scrub down your equipment and growing area between cycles. If you don’t, you may be setting yourself up for problems. MY Do you have a question for Simon?

Record Nighttime High Temperatures Big Deal for Crop Health This summer 93 weather stations in the US recorded all-time nighttime highs, which have a bigger impact on crop yields than increases in daytime temperatures—for each 1°C increase in nighttime temperature above the long term average, a 10 per cent decrease in crop yield was observed.

Don’t Underestimate the Power of Herbal Teas The idea that herbal teas may provide a variety of health benefits is not just folklore. A survey of the research literature on the health benefits from drinking three of the most popular herbals in America—chamomile, peppermint and hibiscus tea—found compelling science-based evidence. • Evidence of moderate antimicrobial activity and significant antiplatelet-clumping activity was found in chamomile tea. • Peppermint tea was found to have significant antimicrobial and antiviral activities, strong antioxidant and antitumor actions, and some antiallergenic potential • Based on a human clinical trial, drinking hibiscus tea was found to lower blood pressure in a group of prehypertensive and mildly hypertensive adults.

E. coli an Unlikely Contaminant of Plant Vascular Systems Scientists have helped confirm that Escherichia coli is not likely to contaminate the internal vascular structure of field-grown leafy greens. There was no evidence that E. coli had become “internalized” in leaves or shoots of baby spinach plants 28 days after the plants had germinated and grown in pasteurized soil.

Boosting the Pineapple Industry in the Bahamas Bahamas Agricultural and Industrial Corporation (BAIC) has started distribution of 5,000 tissue cultured sweet cayenne pineapple slips throughout the islands in an effort to stimulate the Bahamian pineapple industry. The slips were imported and hardened at Nassau’s Lucayan Tropical hydroponics farm. Presently, sweet cayenne pineapples are imported from Costa Rica and sold in the food stores. By producing them locally, there would be no need to import them. BAIC’s next initiative is the distribution of fruit trees—avocado, mango, sour sop, guava, and Persian lime.

Fundraising Effort for Hydroponics A fundraising effort was recently launched for an ongoing documentary project and web series called A Sustainable Reality: Redefining Roots that focuses on the key areas of sustainable indoor gardening. The goal is to raise at least $11,000 to redefine and restructure the concept of food production to enhance sustainability by farming indoors using a grow box and hydroponics systems. In the long-term, the people behind the project hope to expand the scope beyond Chicago and the Mid-West and even to other states and eventually around the world. The mission is to reimagine the current models of sustainability in urban settings, transform long-abandoned decrepit buildings into spaces where visionaries can collectively work on sustainability projects. The project also aims to document and unite a number of individual and community grow projects to create a sustainable hub through donations. (Source: www. onlineprnews.com)

Plant People Promotes Hydroponic Growth Teresa Busch, owner and operator of The Plant People in downtown Juneau, is installing a hydroponic and aquaponic system in her plant shop. The system will demonstrate how growing can be accomplished in local homes to produce produce and other plants without the need for soil. The store will carry the necessary materials and counseling to create similar systems at home, which can be set up in something as small as a fish tank. Part of the elaborate set-up is a backdrop of mountains and sky above the two tiers of pond liners to make the fish feel at home. Vegetarian tilapia and comet fish will live together, be fed from plants and supply their leavings, which in turn will act as vital nutrients for the plants.

Teenager Sells His Hydroponicallygrown Produce What began as a ninth-grade science fair project has turned into an all-consuming enterprise in the Frazier household. Last fall, Brad Frazier, 14, set out to prove that grown using a hydroponic system would outperform tomatoes grown in soil. Six months later, the experiment, which won third place at the regional science fair, has expanded into an innovative and impressive growing operation at their St. Rose, Louisiana home and a subsequent stand at the Gretna Farmer’s Market. Brad plans to expand by building a new greenhouse at twice the size, and a pond for goldfish, coy and perch. At this point the lettuce is Brad’s “prized-possession”. He grows butterhead, oakleaf and baby romaine. He’s found the “baby” or miniature varieties—like his baby cucumbers—are popular among buyers. (Source: www.nola.com)

BASIC PLANT GENETICS by GrubbyCup

The basic principles at work behind the modification of plant genetics can be demonstrated with a simple pack of playing cards. 46

Basic plant genetics

Gardeners have been breeding plants for specific traits for thousands of years. By following the simple rule of “cross your best examples together” substantial modification can be made to any plant over enough generations. Many of the original heirloom vegetables are believed to have been developed using this basic technique. Most of the different varieties of tomatoes we know today are examples of plant breeding and many of them were originally developed by home gardeners. While improvement can be made to plant strains without understanding any of the science behind it, learning even just the basics of Mendelian genetics can greatly improve breeding attempts and doesn’t require an advanced degree in molecular biology. Plants have a number of chromosomes in their reproductive cells. The number of chromosomes depends on the type of plant. For example, peas have only 14 chromosomes, while some strains of wheat have 42. Each chromosome contains many genes, which are the blueprints for how the plant will grow. A plant may have a gene present that

will determine, say, whether it has the instructions to grow red flowers or to grow white flowers. In this example, flower color is a trait and it may be expressed as red or white, depending on the gene. All the instructions contained in the genes are collectively known as the genotype of the plant. It’s true that some complex traits require multiple genes to express, and some traits require specific combinations of genes to manifest. For example, calico cats have to be female, with a different color on each X chromosome. For the purpose of this discussion, though, we’ll keep things simple and talk about an either/or situation: red flowers or white. Mendelian traits are binary; they have two states. Since our hypothetical plant can have either red or white flowers, playing cards can be used to model a single regular trait, controlled by a single gene, located on a single chromosome. Take a deck of playing cards and remove the jokers. Cut the deck in half and create two stacks—the left stack will represent genes from the father and the right stack the genes from the mother. To show your first resulting offspring, place one card from each stack face up. Red cards symbolize the genetic instruction for red flowers and black cards represent an instruction to grow white flowers. There are three possible scenarios governing what the two face-up cards will be. Twenty-five per cent of the time both cards will be red and your imaginary plant will produce red flowers. Twenty-five per cent of the time both cards will be black and your subject will produce white flowers. A plant with two of the same form of the gene is said to be homozygous for that trait. Fifty per cent of the time, however, the pair will consist of one red card and one black card. A plant with one of each of the two forms of a certain gene is said to be heterozygous for that trait. The color of flower that will manifest in a plant that is heterozygous for that trait will depend on which gene is dominant. Simply stated, the dominant gene wins all ties. If the red gene is dominant then the mixed pairs will show red flowers,

while if the white gene is dominant then mixed pairs will have white flowers. In order to keep things simple, we’ll assume that red genes will be the dominant form in our demonstration. Because of the principle of dominance, when both parents are heterozygous the recessive form will present 25 per cent of the time and 75 per cent of the time the dominant form will show up. Even though 25 per cent of the plants are homozygous for the trait and 50 per cent are heterozygous, the resulting plants will have red flowers 75 per cent of the time. To show the result over a number of plants, deal out 25 cards face down in a five by five grid—these will represent the genes inherited from one parent.To represent the gene each plant gets from the other parent, deal a card face up on each of the down cards.

Maximum Yield USA | September 2011

Basic plant genetics

Since red is dominant, for each pair that has a black card face up, flip the pair to exchange the up card and the down card. Approximately 25 per cent of the face-up cards should be black and the rest red. The phenotype is the plant that is expressed by growing out the seed. No matter what the face-down card is, the face-up card determines the phenotype. The genotype refers to both the up card and the down card together. If the face-up card is red, then our hypothetical plant will grow with the dominant trait of red flowers. This will happen

75 per cent of the time, since the four possibilities in the two cards are: • Red, red = true breeding (homozygous) for red flowers. • Black, black = true breeding (homozygous) for white flowers. • Red, black = red flowers, since it is heterozygous and red is dominant. 52

Maximum Yield USA | September 2011

• Black, red = red flowers, since it is heterozygous and red is dominant. In other words, the same ratio we saw before—of 25 per cent recessive to 75 per cent dominant—will occur, but on a larger scale. The reason why understanding these ratios is important is that with real plants, there is no way to peek at the hole card—the only way to determine its value is by testing and deduction. All that can be observed directly is that about 75 per cent of the face-up cards are red. Traits become stable or fixed when the other form of the gene (card color) is eliminated or at least greatly reduced in the gene pool.

If the recessive form of the gene (represented by a black card) is paired with another recessive form (another black card) there will be no ties, as only black cards are available, and the trait will breed true. All the face-up black cards should have a black card underneath as well. This is why recessive traits are easier to breed than dominant traits: if a recessive trait expresses itself, you know it will breed true if crossed with another plant that also expresses that trait. If you take a plant with two black cards and cross it with another plant with two black cards, all the offspring will also have only black cards. Most of the time the face-up card will be red and the plant will show the dominant form of the gene.The reason that dominant traits are harder to work with is that both the true-breeding plants and the heterozygous (mixed card) plants will both express as red flowers. To stabilize a cultivar, as many important traits as possible are bred to be homozygous (both cards of the same color). Since Maximum Yield USA | September 2011

the bottom card can only be indirectly observed, it is more difficult to know the difference between the two. What can be done with dominant traits is to keep breeding plants that appear to be true-breeding for the trait until it is statistically improbable that they aren’t true-breeding. If one of the parents with a red up card has a black down card, you will still get red flowers, but as the generations continue then at some point two black cards will come together in the same plant. This will be a throwback and will show the recessive form. Heterozygy may not be desirable for breeding a stable line, but it can have benefits. Hybrid vigor tends to express itself in heterozygous plants. Because of this factor hybrids are often ideally the product of two true-breeding plants of opposite color—two red cards to two black cards. To observe the effects of hybridization, separate the cards by suits into four stacks. Put the

two red stacks face up together to symbolize the mother and the black stacks face up for the father. The mother plant will show the dominant form since she has a red card and the father plant will not, since both his cards are black. Randomly take one card from one of the two mother stacks. Since all her cards are red it doesn’t matter which stack you take from—the card will be red. Then take one card from one of the father stacks and again, no matter which stack you take from the card will be black. Since offspring get one card from their mother and one from their father, all the offspring will have one black card and one red card. Therefore, the children will all express the dominant trait because they will all have a red card. Hybrids that all have one red and one black card will all show the dominant form and can appear very similar to each other. This technique is often used to create commercial seeds. Hybrids can also express hybrid vigor, which generates superior plants, although one drawback to hybrids is that they do not breed true. In the following demonstration of hybridization all the offspring will have one red card and one black card. Arrange the stacks so that the mother has one red stack and one black stack and the father has one red stack and one black stack.

To simulate crossing the two parents, take one card from the mother (randomly choose between her two stacks) and do the same with the father. Deal several hands, flip the black pairs and what you should find is that the results change dramatically from the original hybrids. While the offspring of the cross making the hybrid creates siblings that are similar to each other, the generation after that will show both dominant and recessive traits. This is how traits can hide or skip generations.

If two plants that both show the recessive form of a trait are crossed, the offspring will also (generally) show the recessive trait. If two plants that both show the dominant form of the trait are crossed, the offspring may or may not all show the dominant traits. If all the offspring show the dominant trait, that is an indication that at least one of parents is true-breeding for that trait. In the generation after that if no offspring display the recessive form of the trait then that is an indication that the line is true-breeding for the dominant trait. It is only an indication, however, since as long as one of the plants involved in the crossing has a black down card the recessive form may resurface in later generations. Keeping good records is a must, and each plant should be evaluated for the desired trait (or traits). By observing traits over several generations and then comparing the results to the ratios from either dealing pairs with different combinations of parent stacks or the mathematical results from a Punnett square, educated guesses as to the value of the unseen facedown cards can be made. Making sense of the mysteries of genetics can take a bit of effort, but by understanding these basic principles you can begin to improve your own seed making results dramatically. MY

Fertilizers

A Sea of Fish by Donald Lester

Despite recent controversy, fish fertilizers can be used successfully in outdoor, indoor, organic and hydroponic gardens. Sound fishy? It’s not. Read on to discover the various advantages and how to implement sea sustenance into your garden.

A sea of fish fertilizers

he use of fish as a fertilizer for food crops has a long history. Perhaps the best-known stories are those relating to the coastal Native Americans placing a whole fish in the planting hole with their corn seeds—fish products have come a long way since then! Fish fertilizers offer several advantages over their chemical counterparts. They can be totally organic, with all the associated benefits such as improved soil structure, increased microbial activity and better plant health, they don’t cause plant burn (phytotoxicity) as readily or as commonly as chemical fertilizers do and they generally have slower, more even release rates so they do not need to be applied as often. Moreover, fish fertilizers are not readily leached from

the soil but are instead slowly broken down by microbes that convert the fish into plant food. Fish fertilizers also often contain trace nutrients not found in chemical formulas. Finally, with the technological advances in fish farming, fish are considered to be a sustainable, renewable resource whereas the mined minerals used in chemical fertilizers are not. Unfortunately, fish products have taken on a bad name in recent years because two unscrupulous fertilizer manufacturers were caught spiking their ‘certified organic’ fish fertilizers with synthetic nitrogen. The main culprit is now out of business but these incidents have created a firestorm of controversy in the organics industry, leaving many to question the thoroughness of the organic certification process. These examples of fraud were an embarrassment not only to the organic certifying agency involved but also to the USDA that oversees the organic certification process—the stories made the national news and congressional hearings were held on the matter. Since then increased oversight has been implemented. Now, any fertilizer considered for organic certification with a nitrogen content greater than three per cent is considered to be a ‘high-nitrogen product’ and is subject to additional scrutiny and mandatory yearly inspections by the organic certifying agencies. Regulatory burdens like this and the resulting increased costs have already driven several organic fish product manufacturers out of the market. Rather than using whole fish as a fertilizer, manufacturers today offer processed fish products in several easy-to-use forms, the most common being fish emulsion, fish hydrolysate and fish meal, all of which are usually available in both conventional and organic versions. Each formulation has its own set of pros and cons for indoor gardening.

Fish meals are made by grinding fish carcasses after a heating process has removed much of the oil—waste water left over from making fish meal can then be concentrated to produce fish emulsions. Finally, fish digested in vats using enzymes or strong acids or bases—instead of heat—produces fish fertilizers called hydrolysates. Basically, this process breaks down protein into its component amino acids, which are the building blocks used by plant cells. Fish emulsion Over the years fish emulsion has meant anything from ground-up fish to fish excrement. In fact, there is a misapprehension that fish excrement or fish emulsion added to a hydroponics system makes it an aquaponics system. But, technically, aquaponics actually refers to a growing system where fish are grown in a tank and their waste is cycled through to the plant roots to act as a natural fertilizer. An aquaponics system does not need additional fish-based products added to work properly. Fish typically have a high oil content, which is beneficial not only for humans but also for plant growth. In recent years, however, omega-3 oils have been singled out for their health

benefits for the heart and brain, which has led to much of the oil being removed from fish products and only the remaining leftovers used for agricultural products. Often users will ask manufacturers what the oil content is in their fertilizer product, and typically the oil content is in the 40 to 45 per cent range. Marine species of fish like salmon typically have higher omega-3 levels and are therefore more likely to be processed for that oil, while freshwater species have lower oil levels to begin with so as a rule they are often considered to be less desirable for use in commercial plant production. In California the rules state that for a product to be a fish emulsion it must contain greater than 40 per cent solids in the product. 60

“Technically, aquaponics actually refers to a growing system where fish are grown in a tank and their waste is cycled through to the plant roots to act as a natural fertilizer.” Some manufacturers have told me they average about 38 per cent solids, so to avoid a penalty for low solids content they avoid using the term fish emulsion on the label at all and instead label it a ‘liquid fish product’. Fish hydrolysate Fish hydrolysates are another class of fish-based product available for use in agriculture and indoor gardening. In commercial fish processing plants the meat is usually removed as a filet and the remaining head and body are discarded. This discarded material is often kept on ice to reduce odor and then sold to other companies like fertilizer manufacturers for further processing into things like fish protein products. Animal protein is not actually very useful in plant production—what is more desirable are the amino acids that make up the protein. There are three primary ways in which to break down protein into its amino acid building blocks: you can treat it with a strong acid (low pH) or a strong base (high pH) or with enzymes. Generally these acids and bases are synthetic in nature and so are not permitted in organic production, but an allowance has been made for manufacturers to allow them to use just enough of these materials to do the job while not adding any other nutrients to the final product. Using an acid has the side benefit of bringing down the pH of the final product into a pH range of 3.5, which prevents the growth of odor-causing bacteria and human pathogens. Enzymes tend to be more expensive than acids or bases. Maximum Yield USA | September 2011

Fish meal Unlike liquid hydrolysates and emulsions, fish meals are granular or powdered in form. Fish is heated to remove fats and oils to use in various health and cosmetics products and the lean carcasses that remain are ground up into a meal, sprayed with phosphoric or sulfuric acid for stabilization and deodorization and then dried. Generally, fish meals contain more protein than emulsions, but less than hydrolysates. Fish meals usually have an NPK analysis of around 10-6-2 or 12-6-2. The high nitrogen content obviously makes them good for vegetative growth and the relatively high phosphorus content makes fish meals good for root development and bloom as well. The downside is that fish meals have a strong odor—after application they continue to smell for a few days and are therefore usually buried into the root zone. They are not recommended for indoor use, but if you can stand the smell they can be mixed into potting or bulk soils where they act as a slow-release fertilizer. Suitability for hydroponics and foliar applications Fish emulsions and fish hydrolysates can be used in hydroponics systems because they are liquid in form. Emulsions are more soluble and some of their nutrients are useable by plants

Fish meal

Maximum Yield USA | September 2011

without the need for beneficial microbiology, but both product types work best in organic systems with microbes present. Toxins and heavy metals may be present in these products and odor is always a concern, especially with emulsions, although some manufacturers are introducing fish emulsion products into the market that have essential oils like lavender added to improve the smell. If you use a filter in your system, fish hydrolysates may need straining to prevent clogging of the filter’s fine mesh screen. For soil applications with a drip system be sure the fish product will pass through at least a 70 mesh screen to minimize emitter plugging and fouling. Beneficial biology Organic fish fertilizers excel at supporting the beneficial microbe populations that are the base of the soil food chain. They all provide some NPK and most of these products, at least those made from sea fish, also provide trace elements, micronutrients, vitamins, minerals and other desirable materials. Fish hydrolysates in particular come about as close as possible to duplicating the practice of burying a whole fish, although the hydrolysis process actually makes the fish more available to microbes, breaking down large molecules into tiny ones.

“Fish meals also support increased microbial activity. They contain tremendous amounts of protein and are a great food source for bacteria and the annuals and vegetables that prefer a bacterial dominance in their soil.”

Microbes can and do readily feed on the organic matter and proteins from the meat and guts. Calcium from the fish bones is also retained in hydrolysates and the oils make great fungal food for those plants that prefer fungal-dominated soils: perennials, trees and shrubs. For this reason, hydrolysates make great fungal food for inclusion in compost and compost teas.

Fish meals also support increased microbial activity. They contain tremendous amounts of protein and are a great food source for bacteria and the annuals and vegetables that prefer a bacterial dominance in their soil. Covered with bacteria, fish meal added to a compost pile gets the pile cooking due to the heat generated by high microbial metabolism. In addition, flies (and fly larvae) readily feed on it, which in turn attracts other members of the soil food web. Not all products sold as fish fertilizers are made just from fish. Some contain non-fish organic additives, primarily seaweed and crab shells. The seaweeds are full of micronutrients and plant hormones like auxins and cytokinins, while crab shells provide chitin, which is found in the cell walls of fungi and is a big structural component in insect exoskeletons. The right fish fertilizers or combinations of fish fertilizer products can be great for your plants. Fish hydrolysates provide more nutrients, vitamins, hormones and micronutrients, fish meals are slower acting but more suitable for outdoor use and larger areas, while fish emulsions are ideal for quick-acting foliar sprays. With such a nice array of choices perhaps you should consider adding fish products to your plant feeding program! MY

Have You Forgotten About Magnesium?

I began my professional career as an assistant professor of agronomy at the Ohio Agricultural Research and Development Center (OARDC). In order to become acquainted with the agricultural industry in the state, I attended regional and county extension meetings, met with farmers and made visits to the outlying agricultural research stations. With the coming of spring, newly planted crops were emerging, new growth was appearing in pastures and trees were advancing into full leaf. With the coming of summer, however, I observed that not all crop plants were growing very well, with visual evidence of a possible nutrient element deficiency—even some of the roadside plants were showing signs of stress. The visual leaf symptoms on all of these plants were similar to those present in magnesium (Mg) deficiencies.

“Most of the plant tissues collected were found to be either deficient in Mg or near what would be considered deficient for each crop or plant species.”

A graduate student in the agronomy department was concluding a long-term corn fertilizer research project on plots that were located on each of the major soil types in the state and he had observed visual leaf symptoms of a possible nutrient element deficiency on corn plants in some treatment plots. I had him collect corn leaf tissue from all of the plots for elemental analysis and in my visits to the various outlying research stations I also collected soil samples and leaf tissue from plants showing symptoms. That fall and winter was spent assaying the soil and plant samples collected and then making an evaluation of the results. Most of the plant tissues collected were found to be either deficient in Mg or near what would be considered

“It turned out that stress was the factor that had contributed to the widespread appearance of Mgdeficient plant leaf symptoms.”

deficient for each crop or plant species. Most of the soils collected with the plant tissues, however, soil-tested sufficient in Mg, based on current soil testing interpretation criteria. A colleague and I then decided to do a more detailed analysis that would require us to collect sufficient quantities of soil in order to conduct a greenhouse study. With the coming of the next crop year, we made preparations to revisit those sites where I had collected plant tissue and soil samples the year before. But as the season progressed, the expected symptoms of Mg deficiency did not appear! No more widespread signs of Mg deficiency were seen in field crops or even among roadside plants. So what had been the cause for the high incidence of Mg deficiency symptoms seen in many plants throughout the state the previous year? The answer was that the previous year was the final year of a succession of summers of low rainfall and high air temperatures, coupled with high light-intensity days due to cloudless sky conditions, meaning that plants had undergone a

Maximum Yield USA | September 2011

Have You Forgotten About Magnesium?

number of years of moisture and heat stress. Now, with more normal rainfall, moisture stress was at a minimum, while air temperatures were also within their normal expected range and cloud-covered days had returned. It turned out that stress was the factor that had contributed to the widespread appearance of Mg-deficient plant leaf symptoms and that these symptoms had then disappeared when growing conditions became less stressful. At one time Mg was classified as a secondary element along with the elements calcium (Ca) and sulfur (S). Today, that classification has been dropped and Mg, Ca and S are classed as major elements, in the same grouping with the elements nitrogen (N), phosphorus (P) and potassium (K). An atom of Mg is in the structure of the chlorophyll molecular. Magnesium acts as an enzyme activator in various energytransfer functions in plants, so any deficiency will slow plant growth. The visual leaf symptom of a Mg deficiency is a chlorosis appearing on older leaf tissue, which is an indication that this element is mobile in the plant. For those growing in soil, Mg sufficiency is usually assumed when the soil is adequately supplied with Ca and the soil water pH is within the recommended range. However, Mg soil availability is pH-dependent and if the soil water pH is less than 5.4 Mg deficiency can occur even when soil Mg availability is classed as being sufficient. When liming an acid soil based on a soil test recommendation, the form of limestone recommended

may be specified depending on the soil test level for Mg. If the level is less than sufficient, dolomitic limestone would be recommended, since this form of limestone contains Mg. Among the three cations, K+, Ca2+ and Mg2+, the Mg2+ cation is the least competitive and its deficiency can be induced when both K and Ca are at high levels in the rooting medium, whether the rooting medium is a nutrient solution or a solid matrix. Ammonium (NH4+) is another cation that is highly competitive among the three major cations and its presence in the rooting medium can be a factor in creating Mg deficiency in a plant. There are plant species and varieties within species that are sensitive to Mg and deficiencies can occur when the plant is under moisture or temperature stress, even when there is sufficient Mg in the rooting medium or in that being supplied by a nutrient solution. Tomato is a plant that would be classified as Mg sensitive. Among field crop plants corn is also Mg sensitive, although plant breeding has reduced this sensitivity to some degree. The appearance of visual Mg deficiency symptoms in greenhouse tomatoes is not an uncommon occurrence when plants are setting and maturing fruit, as this function acts as a form of stress on the tomato plantâ&#x20AC;&#x2122;s metabolism.

“Tomato is a plant that would be classified as Mg sensitive. Among field crop plants corn is also Mg sensitive, although plant breeding has reduced this sensitivity to some degree.” of growth will not correct the deficiency, though, as its origin occurred during the vegetative plant growth period, either due to insufficient Mg being supplied or as a result of an imbalance among the major cations that reduced Mg root absorption. Although insufficiency of Mg during vegetative growth may not result in visual leaf symptoms it can eventually be a factor resulting in lower than expected fruit yield. Based on my own hydroponic tomato growing experience, I have increased the Mg content in the Hoagland/Arnon nutrient solution formulation by 50 per cent, so that when the tomato plant enters its reproductive stage there is sufficient Mg in the plant to advert the potential for deficiency. I believe that many nutrient solution formulations are insufficient in Mg or that the other major cations in the formulation are at such concentration levels that Mg root absorption is impaired—the Steiner concept of elemental balance among the ions in a nutrient solution addresses the issue of cation balance as essential to ensure plant nutrient element sufficiency1. Most hydroponic nutrient solution formulations do not take into consideration the effect that Mg concentration and its ratio among the other major cations can have on the potential for creating a Mg insufficiency. What determines Mg sufficiency in a rooting medium and within the plant is a complex subject, with the occurrence of its insufficiency being the result of various factors as discussed in this article. Magnesium is an essential plant nutrient element that has attracted little attention, but its insufficiency can significantly affect plant growth and fruit yield. How do you avoid an insufficiency? You should ensure that there is sufficient Mg in the rooting medium—in proper balance among the other cation essential nutrient elements—and that those factors that can place undue stress on your plants be minimized.

Water by Michael Bloch

Drought is a part of normal life in many parts of the world and given the threats posed by climate change combined with traditionally low rainfall, growers and non-growers alike need to keep their clean water supplies high. A rainwater tank is a sustainable option to help through lean times. Water tanks haven’t been an overly attractive home addition until recently.These days, tanks come in many shapes, colors, materials and sizes to suit any home and space. If having a full size water tank isn’t an option for you, rain barrels are a very affordable and easy-to-install option.They look like a pickle barrel, are mostly made of plastic and hold up to 80 gallons. In this article we’ll take a brief look at the various materials commonly used to construct larger tanks—and the various advantages and disadvantages.

Poly (plastic) rainwater tanks Poly tanks are made from polyethylene, a UV-stabilized, food-grade plastic.These tanks are light and have a long, serviceable life. Many poly tanks carrying a 25 year warranty, although many claim 15 years is a more realistic lifespan.They are also usually the second cheapest of the options covered in this article.

One of the major disadvantages of polyethylene is the material is made from petrochemicals, meaning this big hunk of plastic will take generations to breakdown and it will release toxins in doing so. However, polyethylene tanks can be easily recycled after 15 years, so it’s just a matter of breaking the tank up and carting it to a recycler. Some poly tanks are made with a vertical seam; this is a weak point that may cause splitting and subsequent water loss so a seamless tank is probably a better choice. Polyethylene water tanks and fire don’t mix as they’ll just melt should the flames get too close. The other issue is the effects of drinking water stored for such a long time in this material. Polyethylene tanks are relatively new on the market, so there are no serviceable life studies in relation to these issues as far as I know. I had a polyethylene rainwater tank at my old place where temperatures would get up to around 114°F in the shade and below freezing during winter.The tank performed well over the couple of years I had it before selling the property, but there was a bit of an odd taste to the water on hot days.A subsequent poly tank I acquired for my current property has also stood up well to similar extremes, and without the odd taste. Before purchasing a poly tank, check the warranty for temperature stipulations as some manufacturers will void the warranty if the tank is installed near extremely hot conditions.

Steel tanks Galvanized tanks have been around for over 150 years and are usually the cheapest option. Hot-dip galvanizing is a process used to coat steel or iron with zinc.The zinc helps slow down corrosion, but depending on environmental factors, a galvanized tank may last well under five years, particularly if the roof of the structure capturing the rainwater is made from Zincalume, due to electrolysis. Zincalume® has been around for about 30 years and was originally used for roofing. It’s a mix of 55 per cent aluminum, 43.5 per cent zinc and 1.5 per cent silicon bonded to steel.There’s a lot of conflicting information around about lifespan, but the general consensus seems to be about 10 to 15 years. Some metal tanks now also have polyethylene linings to further slow down corrosion. If you do buy a steel tank, look into installing extra sacrificial anodes to further delay corrosion.

Concrete water tanks Concrete rainwater tanks can be installed either above or underground. The latter is a good option if you’re short on space as they can be constructed to allow for load bearing, for example, under a driveway.

Given the material, they are very heavy and often poured on-site or delivered in sections that are then basically cemented together. Again, a polyethylene liner may be used.Without a liner, the tank will leach lime and over time you’ll have slightly alkaline water. Concrete is porous so without a liner water will penetrate into the concrete over time, which may cause corrosion of steel framework. Concrete is also an energy-intensive product that requires a great deal of heat and water in its production.

Fiberglass This is another long-lasting option that can be installed above or underground. Fiberglass tanks resist corrosion and are not generally affected by chemicals.As fiberglass tanks tend to allow more light in than other types of tank materials, this can encourage the growth of algae, so they should be painted or a gel coat should be applied. Fiberglass can also be brittle, leaving it prone to cracks; something you don’t want, particularly in an in-ground situation.

Choosing a tank material Choice is wonderful, but as you can see, there are advantages and disadvantages with each type of tank—particularly when it comes to environmental impact—so it’s really a matter of gauging your needs and budget and then choosing the lesser of the evils. In regards to the required investment, you should bear in mind the initial cost and possible replacement costs. Rebates on rainwater tanks and associated plumbing are working checking into; many governments now offer cash-back schemes. Even with the various disadvantages of each material, given the length of serviceable life of most tanks and the tens of thousands of liters of water you can collect over that time; installing a rainwater tank is still a very green move.

A brief note on rainwater tank regulations Before buying and installing a tank you should check with your local authorities as in some places you will need a special permit and in others they may be totally banned. MY About the author:

Fodder Dr. Lynette Morgan

T h e r e ’ s n o d o u b t a b o u t i t: h y d r o p o n i c s isn’t just for humans. Fresh fodder g r o w n h y d r o p o n i c a ll y c a n b e f e d t o livestock, zoo animals and even pets.

We usually think of hydroponic or indoor crops as being destined for human use, but livestock and pets can also benefit from hydroponic growing methods. Many of us are familiar with wheatgrass shoots grown in trays and snipped to produce a healthy juice —the principal of hydroponic animal fodder is exactly the same, only the livestock eat the entire product, root mat and all, without the need for any expensive juicing equipment. Although green fodder production using sprouted grains is not a new idea, using modern technology and methods to produce high volumes of quality animal feed in a small space is something that has a lot of appeal today. The great thing about hydroponic fodder is that it can be produced by everyone from pet owners to very large-scale commercial operations with considerable benefits to livestock health and productivity. What is hydroponic fodder production? Hydroponic green fodder is essentially sprouted grain such as wheat or rye—or barley, which works best. The grains are soaked, laid out onto growing trays or channels and left to germinate under ideal temperatures of 60 to 75°F. While the grain initially contains enough storage reserves to fuel growth for the first few days, a complete hydroponic nutrient solution is then given to the developing fodder shoots to boost nutrition and produce a better product. Every two pounds of grain produces between 15 to 20 pounds of fresh green feed after seven to eight days and the resulting feed consists of large thick mats of shoots and roots that are then fed entirely to livestock.

The benefits of hydroponic fodder Using fodder systems has allowed farmers with relatively small blocks of land to run higher stock numbers than would normally be possible by supplementing grass or other feed with fresh fodder on a daily basis. Feeding high-value animals such as horses, which need a certain level of quality nutrition, is another area where commercial fodder systems have been put to good use, particularly in areas where grass production is low for many months of the year.Young or sick animals—as well as breeding, lactating and fattening livestock and those being housed indoors—can all obtain enhanced benefits from fresh fodder year round as a supplement to dry feed, and they enjoy the juicy shoots once they become familiar with the mats of fodder. Hydroponic fodder has been fed to livestock as diverse as dairy and beef cattle, sheep, goats, pigs, horses, rabbits, poultry and deer in both commercial and domestic applications. Well-designed hydroponic fodder factories are also very economical with water and fertilizer. In these systems the nutrient solution is circulated round the trays of sprouting fodder so there is maximum efficiency and no wastage of valuable nutrients. Why sprouted fodder? There are numerous benefits to feeding sprouted grains. Many of us are familiar with the health benefits of wheatgrass, which

is essentially a type of fodder that is cut when young and juiced for us to drink. However, hydroponic fodder goes one step further, as the livestock actually consume the root mat, grains and 10 inch shoots, thus ensuring they get the most nutrition possible from the entire system. While wheat shoots are grown hydroponically in NFT systems for food juicing, animal fodder systems often utilize only barley grain. Seed barley (Hordeum vulgare) has proven to be one of the best grains in terms of production and animal nutrition and is in fact recognized as being one of the most nutritious of all plant foods, containing a broad range of essential vitamins, minerals and amino acids in high concentrations.Young green barley leaves are almost 40 per cent protein; protein which is 90 per cent usable and easily digested and assimilated. Cereal grains are high in phytates, which are enzyme inhibitors. As the seed germinates the phytates are eliminated and this allows maximum absorption of the nutrients contained in the grain. Many other nutrition changes occur in the sprouting grain as well—complex compounds break down into

and free folic acid in sprouted grains are often more than tenfold. Nutritional feed analysis of hydroponic barley fodder has found protein levels of up to 40 per cent, amino acids at 12.9 per cent, carbohydrates at 71 per cent and fat at three per cent, as well as enzymes, vitamins and minerals—including potassium, calcium, magnesium, iron, manganese, zinc, beta-carotene, B1, B2, B6, C, folic acid, chlorophyll and alkalinity (required for animal diets). Finally, fresh fodder does not cause acidosis in livestock in the way that dry grain can.

Fodder systems—big and small Fodder system package deals consisting of growing sheds, channels, nutrients and equipment to provide the correct growing environment and nutritional system for maximum feed production are now commercially available.

produce is considered superior to many other types of feed available for livestock. Fodder-production systems for livestock are essentially the same as those used for many other crops, such as lettuce, herbs, microgreens and even the human equivalent of fodder—wheatgrass for juicing. NFT—or nutrient film technique—is the preferred method of fodder production, although other systems using overhead misters that deliver water and nutrients to the trays of sprouting grains are also sometimes used. In NFT systems large shallow channels contain pre-soaked 88

grain, while hydroponic nutrient solution flows through these channels at a shallow depth, providing mineral elements and moisture. Within 24 hours the barley or wheat grains begin to sprout and rapidly send up fresh green shoots—and at the high density the grain is sown at, a dense mat of fodder is ready to harvest within a week.

The main concern with sprouting grains for both animal and human consumption is hygiene and climate control. High humidity around the developing grain can lead to the development of certain bacteria and fungi, some of which produce toxins that can lead to animal health problems. The best way of combating the growth of these naturally-occurring fungi is to not sprout the grains in a high-humidity environment and to ensure there is adequate air movement around the developing fodder, to keep everything as clean as possible and to use bottom-watered systems such as NFT rather than overhead misting. Some growers, particularly those just growing a few trays of fodder on a small scale, pre-sterilize their grains with a short soak in a diluted household bleach solution to kill off any fungi spores naturally occurring on the grain. A one per cent solution of bleach should be used to wash the grains for 10 minutes before rinsing with fresh water several times, then soaking and

sowing into the fodder system or trays. Water should also be treated to make sure it is clean before applying to the grains and general hygiene procedures—such as washing and sterilizing trays between crops of fodder—should be maintained in order to produce a clean and healthy product. A crop of fast-growing grains under ideal conditions of temperature and humidity will produce healthy fodder at a rapid rate. Although wheat and barley will sprout and grow under cooler conditions, temperatures of 60 to 75°F provide the fastest rate of production and lessen the possibility of any problematic fungi developing.

Healthy, dense fresh shoots, fodder requires a clean system and humidity control to prevent fungal diseases outbreaks.

Maximum Yield USA | September 2011

Wheatgrass is commonly used as a popular juice for humans, but is also a nutritional fodder for a range of animals.

Most hydroponic fodder systems for small-scale feed production for a few animals don’t really need a lot of space. The growing trays or channels are usually stacked into a tiered system of shelves from floor to roof, allowing sufficient space for the sprouts to grow upwards and for air movement over the trays. Hydroponic fodder grown on a large scale is typically produced in specifically designed, climate-controlled sheds rather then greenhouses, as high light levels are not required. However, many smaller-scale fodder producers modify existing buildings or use shaded greenhouses or propagation areas, provided they are warm, free of rodents and can be kept clean and dry. Fodder production with indoor grow rooms Growing fodder indoors offers the same benefits as other hydroponic crops. The main advantage is complete control over the environment, which is essential for high-quality, healthy fodder growth. Like many crops grown at a high density, the sprouted grain is prone to problems originating because of high humidity, a condition in which many fungal and bacterial pathogens thrive. Maintaining the right temperature range (60 to 75ºF) and humidity level (70 to 80 per cent) as well as a good degree of airflow in the grow room area will provide the best fodder growth and nutritional value. Lighting for indoor fodder production doesn’t need to be intense, but it does need to be of sufficient strength to promote a good degree of chlorophyll formation. Compact fluorescents are ideal, as additional heat from

Maximum Yield USA | September 2011

overhead lamps can scorch tender new shoots. While automatic systems such as wide NFT channels are used for commercial fodder production, in a small indoor system hand-watered shallow trays stacked on tiers to maximize production space are a good option. Trays should have drainage holes in the base and will need to be checked and watered once or twice daily, but with the average crop taking less than 10 days to mature a full tray of healthy green fodder can be grown with very little effort. A simple ebb and flow system with a solid tray placed underneath the perforated sprouting tray holding the grains is the best system for manual watering, rather than pouring water and nutrient solution over the crop. Water alone should be given for the first few days as the grains sprout, then a dilute, complete hydroponic nutrient solution—a grow formulation—can be applied at an EC of 0.8 to one mS cm-1. The entire tray of fodder can then be offered to pets or livestock to graze or the whole mat of fodder, roots and all, can

Trays should then be thoroughly sterilized before reseeding with the next crop. If any fungal growth (mold) or bacterial disease (slimy grains) has developed during the fodder production process the tray should be discarded, sterilized and re-sown with clean grains. Fodder for pets The diets of many animals can benefit from supplementation with fresh green fodder and while the main commercial use of hydroponics fodder factories is for larger livestock such as cattle, deer and horses, smaller animals and pets also enjoy fresh hydroponic sprouts on their menu. Zebras in zoos, petting animals, rabbits and poultry are some of the livestock known to enjoy a feed of hydroponic fodder, particularly if they are housed indoors or in areas suffering drought or low wintergrass production. Fresh hydroponic fodder may also prove to be a valuable and cost-effective supplement to help hens produce higher-value, more ‘consumer-friendly’ eggs when access to outdoor green feed is limited or not possible. If you have livestock pets or hens, providing a few trays of sprouted green fodder can give them a higher degree of nutrition as well as cut back on the cost of providing them dry feed.

Biological Diversity and Microbe Strength by Evan Folds

All microbes are not created equal. Discover when microbes are the most effective and at their most powerful in a living system, like a plant.

Maximum Yield USAâ&#x20AC;&#x201A;|â&#x20AC;&#x201A;September 2011

We know a lot about microbes but relatively little about what they actually do or how to use them to help us grow plants. This can be illustrated through a discussion of compost tea. Our current understanding of how to best view microbes and brew compost tea when growing plants is limited. It seems that most of the energy being put into biological research of compost tea in the gardening and agricultural industry is with regard to the identification of groups of microbes—whether active or inactive, fungi or bacteria—and not what those microbes can do within a living system. It’s much easier to create grids and count microbes (which is all a lab does for routine biological assays) than it is to patiently perform growing trials to determine the ability of specific microbes in assisting plant growth. By specific microbes I’m not just talking about categories, but individual microbial strains. For instance, microbes from a farm are far stronger and capable than those from a lab. Total numbers can be relevant when evaluating the balance of biological products or whether a humus product is stable, but it does not address the most important aspect of all—which is how well the product works. The most important things to plants—microbial strength and diversity—cannot be measured or seen under a microscope. Maximum Yield USA | September 2011

Biological Diversity

Rudolf Steiner said, “Human beings want to receive everything passively, to sit down in front of the world as though it were a movie, and let the microscope and telescope tell them everything.”

“As humans, we tend to want to rip things apart to find the truth when the truth lies in the whole synergy of life.”

What he means is that the most important aspects of life cannot be quantified. They’re unobservable. As humans, we tend to want to rip things apart to find the truth when the truth lies in the whole synergy of life. Here’s a truth: all microbes are not created equal. The same truth holds for people, animals and plants. This is why we keep motherplants and clone them. Humans don’t evolve much any more so we have developed extreme diversification, but survival of the fittest is at work in evolving systems. Consider chimpanzees and bonobos—they come from the same genetic stock and grow up basically across the river from each other, but exhibit wildly different characteristics. Now consider the differences in the strength, diversity and ability of microbes that come from a biodynamic farm versus a laboratory. Some biological products in the progressive gardening industry are created from microbes raised by humans in laboratories. This biosynthetic approach is necessary for the cost-effective distribution of certain microbes in specific applications and has its merits—especially with mycorrhizal fungi—but a biosynthetic approach cannot approach the full potential of an intact biological network or soil food web. There’s no synergy among the different microbes because they didn’t grow up together. Imagine if a trapeze artist picked someone out of the crowd to catch them at the end of their death-defying pass. 98

Maximum Yield USA | September 2011

Microbes aren’t robots; they’re unique, dynamic, living, breathing life forms with varying abilities, even within a given species. No living organism operates autonomously. In other words, there is a symbiosis, or give and take, found in the natural world that we humans take for granted and therefore try to restrict. When we get in the way of nature, we mess with the magic. All microbes operate by way of teammates. They play off of each other, with one teammate unlocking the ability of the next. The big man cannot dunk without the assist from the point guard. When 52 different organisms that were individually grown by a human in a petri dish are brought together as an end product intended for use in a gardening situation, the result is compromised. Not only is the overall biological ability of the mixture hindered due to all the players not being on the court, but what happens if the coach has put the players in the wrong positions? What if the benchwarmers, or worse—people from the stands—are put on as starters? The word diversity with regard to biological organisms is used far too casually and confidently. True diversity as nature intends it cannot be measured by data points and cannot be engineered—it must grow from natural impulse and necessity. For instance, you can’t reverse engineer the natural balance in sea water, and the same goes for humus. Be assured, most of the companies out there advertising biological diversity are not performing DNA testing on their organisms and this is the only way to measure true diversity. Besides, biological diversity is virtually limitless, as evidenced by all the superbugs being discussed with regard to the overuse of antibiotics in humans and livestock. Microbes can react and adapt by design. When using microbes, starting with a quality product is essential. This is a major problem with people who compost in their backyards. Organic matter doesn’t just melt; it’s Maximum Yield USA | September 2011

“It’s true that not cleaning a compost tea brewer can generate biofilms, or colonies of anaerobic organisms that spew potentially pathogenic organisms over time.

biologically digested. Without good microbes present in the mix, good plant food cannot be created. For instance, it would not be advisable to use manure to make compost tea because manure is not yet plant food. This is why some compost brands at the hardware store cost a dollar a bag—all they are is aged manure. They’re mulch, not plant food. Remember, trees in a forest don’t eat leaves; they eat what the microbes make of them. Some tea-brewing systems advise using worm castings as a primary food source. While this is certainly a viable option to brew tea, it is somewhat limited because worms are predominately bacterial organisms. Worms utilize bacteria in their gut in order to work their magic, like termites use fungi to digest the wood they eat. You should use worm castings as an amendment—along with a balanced humus product—as castings alone may not contain some trophic levels of the beneficial organisms that provide vital benefits to plants and gardens. Again, all compost is not the same. Let’s use the biodynamic method as a means of illustrating this point. Generally, biodynamic compost is not turned 100

Maximum Yield USA | September 2011

like traditional compost; it is created over longer periods of time. While turning compost does serve to speed up the decomposition process via aeration, it can also sacrifice the potential result by oxidizing the organic matter. Good things come to those who wait. It is possible to change the look and consistency of organic matter via frequent turning, but this again creates mulch, not true plant food. Because biodynamic compost is not turned, the microbes have to do the work, and they’re fine with that. You don’t have to turn the forest floor or a prairie, right? The ability of certain aerobic (air-loving) microbes to become anaerobic if exposed to differing conditions is called facultative. The secret is in creating proper conditions, not in compensating for a lack of biological or energetic balance. It’s true that not cleaning a compost tea brewer can generate biofilms, or colonies of anaerobic organisms that spew potentially pathogenic organisms over time. But some of the more common microbes we are told to fear, such as E. coli, are found naturally in the soil on farms and in our backyards.

There are even anaerobic organisms such as bokashi—or effective microorganisms as they are known—that are becoming popular to those in the know. Their use is sometimes referred to as composting, but is actually fermentation by way of anaerobic microbes. This is not to say that biodynamic compost is anaerobic, but to say that the biodynamic method represents a means of providing microbes more life experience—in other words, more strength and diversity—than those given a cushy couch potato environment. Think of it this way: an unchallenged microbe is a lazy microbe, and you can’t tell good microbes from bad ones by looking at them. Can you see nitrogencycling or enzyme production capabilities in an organism under a microscope? The short answer is—no. My point is that one cannot truly evaluate the quality of a biological product through a lab assay or by peering at a sample under a microscope. The only way to do this is by using it and learning from your subjective experience. Keep in mind also that raw organic inputs need a biological component to make them fully available to plants and that this is true even for good organic potting soils. Finally, microbes should be utilized in all growing situations, hydroponics included. MY

Measuring Light Intensity by Philip McIntosh

Historically light intensity has been measured in a number of ways. It is complicated by the fact that light is something that we humans perceive in a specific way. Our eyes are sensitive to only a small fraction of the total electromagnetic spectrum, and our thoughts about what light is are influenced by this limited perception. The light requirement for a reading room is different from that of an office space, which is in turn different from that of a factory floor. Early light research focused on human perceptions and needs and so was biased toward the view from the human eye—not the view from the photosystems of plants. Plants have their 102

Maximum Yield USA | September 2011

own specific requirements that are not aligned with those of humans. You will see the terms candelas, lumens, footcandles, candlepower, lux, moles, Einsteins and photosynthetic photon flux density used to describe light as it relates to plants and photosynthesis. What do these terms mean?

Candlepower.

Lumens.

Candlepower (cp) is an obsolete unit of luminous intensity based on the light emitted from a specific type of candle (in England the candles had to be made of pure spermaceti weighing 1∕6 of a pound and burning at a specified rate; that should tell you how obsolete this unit really is). Candlepower was deprecated in 1948 and there is really no excuse for still using it.

The lumen (lm) is the SI unit of luminous flux (meaning something like “flow of light”), and is best thought of as a unit of perceived light power or total visible light from a source. High output lights are perceived to be brighter and have more power than dim ones; thus they output more lumens. A lumen is based on the unit the candela, and represents a light source with a radiance of one cd/sr. Keep in mind that the farther you are from a light source, the dimmer it looks but it still outputs the same number of lumens. But, there is less light energy falling on a surface as the source is placed farther away.

Footcandles. Another obsolete unit, the footcandle (fc) (also foot candle or foot-candle) is a unit of illuminance, equivalent to the light shining on a surface placed one foot away from a source having an intensity of one candle (a candlepower of one). Although you may still see footcandles (or even candlepower) in older literature and even on some light meters, lux (one fc = 10.764 lux) is the preferred illuminance unit.

Candelas. The candela (cd) replaced candlepower as the SI unit of luminous intensity. It is defined as the luminous intensity in a given direction of a source emitting 555 nanometers radiation with a radiant intensity of 1/683 watt per steridian (sr). Steridian, now there’s a unit you don’t come across every day! A steridian is roughly the area covered by 1∕12 of a sphere having a radius of one unit. The 555 nanometers wavelength (green) was chosen to correspond to the wavelength of highest sensitivity of the human eye when adapted to bright conditions. Perhaps you can already see a problem with the fact that green light was chosen as a part of the definition and method of producing a standard reference source for the candela; this is not an efficient wavelength for plant photosynthesis.

Lux. The lux is the SI unit of illuminance. Lux gives the number of lumens per square yard (the illuminance) on a surface. For example, if a luminous flux of 100 lm, is shone on an area of one square yard, the illuminance is 100 lux. One hundred lm concentrated on a four square inch surface (perhaps by moving the source closer to the surface) results in an illuminance of 10,000 lux—the illuminance is 100 times as high since the area of a four inch by four inch surface is 1/100th the area of a square yard. Knowing this does not give any information about how much of that is light is actually useful for plants.

Moles, Einsteins and Photon Flux Density. The mole (mol) is Avogadro’s number of any kind of discrete particle. Avogadro’s number, 6.022 x 1023, shows up all over the place in physics and chemistry. As a simplified example of how it’s used, if you have one mole of oxygen atoms, you have 6.022 x 1023 oxygen atoms. If a mole of oxygen atoms is combined with two moles of hydrogen atoms you will get one mole of water (H2O).

Named for the scientist (in honor of his 1905 description of the photoelectric effect, in which certain materials eject electrons when struck by light), the Einstein (E) is a unit (but not an SI unit) of quantized light energy. The Einstein is sometimes mistakenly described as one mole of photons of any wavelength. However, it is really the amount of energy (in joules/mol), of a mole photons of a given wavelength. A mole of photons is quite a lot, so in plant research, photosynthetically active radiation (PAR) measurements are reported in microEinsteins per second per square yard (micro = one-millionth). Or, to be consistent with SI units, micromol per second per square yard. These data are collected using sensors that essentially count all the photons in the range from around 300 nanometers to 700 nanometers. This is also known as the photosynthetic photon flux density (PPFD) or photosynthetic photon flux (PPF). MY About the author:

Unique Heirloom Tomatoes

“There are so few choices of tomatoes in the average grocery store because of seed companies and the farmers they do business with. “

Have you ever noticed when browsing through your local grocery store how there are only a few different varieties of vegetables, fruits and herbs to choose from? Why aren’t there more options and where have all the other cultivars gone? When I go shopping for food I am lucky if I can find two or three different types of tomatoes available for sale—there is usually only a medium-sized, red beefsteak hybrid and a red vine tomato hybrid available, and neither offers much in the way of flavor or appearance. So why are there not any alternatives? The reason for this lack of selection is somewhat disturbing. There are so few choices of tomatoes in the average grocery store because of seed companies and the farmers they do business with. The large seed companies have genetically modified the tomato seeds that they are selling to the farmer, designing them to grow more tomatoes in less time, using fewer nutrients. These seeds are generally the only seeds available to the large-scale farmer and since the seeds are hybrids, they cannot be reproduced; instead the farmer must continue to purchase seeds from the seed company each year in order to sow the crop.

The fruit is bright uninterrupted darkness, which simulates the amount of light the plants would receive if they were grown outdoors. This strain usually grows four to six feet tall, although it can get larger, and the plants need a daytime temperature between 65 and 85°F and a nighttime temperature no lower than 55°F. Persimmon tomatoes have an ideal pH range of 5.5 to 7.0 in soil and 5.8 to 6.4 in hydroponics—if the pH level drifts out of this ideal range the plant will begin to lock out nutrients and deficiencies will develop. Persimmon tomatoes are open-pollinating: when growing these types of plants indoors you must pollinate them by hand, which is best accomplished by touching the tip of a paintbrush

to each flower twice a day while the plant is in bloom in order to spread the pollen from flower to flower, male organs to female organs. All things considered, the Persimmon cultivar is an excellent heirloom tomato that takes about 80 days from seed sowing to fruit harvest. Another unique tomato cultivar is the Purple Calabash, which is said to date back to pre-Columbian Mexico. Two to three inches in diameter, Purple Calabash tomatoes have a rich purple or chocolate brown hue with purple, green or pink interiors and deep ridges, making them resemble little pumpkins. They have a rich, complex flavor which has been compared to wine, are unlikely to crack or blemish and are drought tolerant and disease resistant. Purple Calabash tomatoes are great for making salsa, bruschette,

110

sauces and salads, or simply on their own. Purple Calabash tomatoes can be culti-

vated at home fairly easily. They need lots of light to produce great fruit, so growing them under HIDs is recommended. For the vegetative stage of growth this strain needs 18 hours of uninterrupted light, while in order to get the plants to flower indoors you’ll have to switch the

photoperiod to 12 hours of uninterrupted light followed by 12 hours of uninterrupted darkness. Purple Calabash tomatoes also need to be hand pollinated when grown indoors. The ideal pH range for Purple Calabash tomatoes is from 5.5 to 7.0 in soil and between 5.8 and 6.4 in hydroponics. This cultivar can grow anywhere from four to eight feet tall and staking the plants is recommended to keep them from falling over and being damaged. Purple Calabash tomatoes are an indeterminate strain—which means that their fruit does not develop and ripen all at once—and it should take about 75 to 85 days from seed sowing to harvest. The next cultivar that we’ll look at is the Reisetomate, an extremely rare German heirloom strain that just might be the most strange and unique tomato

Maximum Yield USA | September 2011

111

Unique Heirloom Tomatoes

cultivar that I have ever come across. The Reisetomate is called the travel tomato—and for good reason. The fruit produced by this strange tomato plant resembles red cloves of garlic and the Reisetomate is essentially like a cluster of cherry tomatoes that has fused together. They make tasty and convenient snacks to travel with because you can break off the tomato a piece at a time while doing little damage to the remaining fruit. In fact, each piece has the makeup of an individual tomato, with skin, flesh and a core full of seeds, despite the fact that they are all fused together to make up one large fruit. As far as flavor is concerned the fruit of the Reisetomate is tasty but hardly extraordinary—it’s really more of a show tomato, something to blow the minds of those conditioned to grocery store hybrids. Reisetomate tomatoes are relatively easy to grow indoors and since they’ll only grow from 24 to 36 inches in height they’re a good choice for smaller indoor spaces.They’re an indeterminate strain—so the fruit will develop gradually and not all at once—and they’re resistant to many diseases such as fusarium wilt, verticulum wilt, root nematodes and tobacco mosaic.While their ideal pH range is the same as the other tomatoes we’ve discussed, Reisetomate plants can tolerate somewhat lower temperatures. Like most tomato strains Reisetomate plants require lots of light to produce fruit and they do best under HID lights. They need 18 hours of uninterrupted light for the vegetative stage of growth, although in order to trick the plant into flowering you’ll have to switch the photoperiod to 12 hours of light followed by 12 hours of darkness. Like the other strains we’ve discussed Reisetomate tomatoes will also need to be pollinated by hand in order to produce fruit indoors. One safety note for the home grower—certain parts of all tomato plants are toxic and must not be consumed, as the leaves and stems contain small amounts of a toxin called tomatine. MY

Micropropagation by Brian Johns Discover the basic steps of micropropagation, but before we begin all that, there is one point that cannot be stressed enough—maintain cleanliness! All other factors in micropropagation are important but none of them will affect your results as much as this one.

114

Maximum Yield USA | September 2011

1. Select a plant from which to take tissue samples. It is important that your plant is free from any visible signs of disease or infestation. Typically plants that are grown indoors are more successfully micropropagated than those grown outdoors simply due to lower levels of contaminates. It is also important to sterilize your plant as much as possible. Wipe the plant down with a mild bleach or hydrogen peroxide solution (approximately ½ teaspoon per .22 gallons). 2. Select the appropriate containers in which you will be placing your grow medium and tissue cultures. This can be something as simple as baby food jars. I recommend small mason jars because they are glass (easily sterilized); you do not have to remove any labels (labels block the plants from receiving light and you don’t want that); the lids can be easily adjusted to accommodate more or less airflow; and they are readily available and inexpensive. 3. Prepare your grow medium. There are many different forms of grow mediums suitable for tissue culture on the market today. The advantage of purchasing a prepared grow medium is that it takes a lot of the guesswork out of the process. Also many of the prepared grow mediums are plant specific, which means they contain all of the appropriate minerals, nutrients and hormones needed for your specific plant. (Note: Prepared grow mediums are only partially prepared as there is some mixing involved).You also have the option to mix your own grow medium. 4. Take cuttings from your plant and place them into the grow medium. The best way to do this is with a scalpel and tweezers that have been sterilized. As it pertains to what sections

of the plant to take your cuttings from, this is one area where you get to experiment a little bit. With some plants, even sections of the leaf tissue will root and form clones, so be creative and take samples from various locations of your plant and keep track of which cuttings work best. It is important to think small when taking your cuttings. All that is needed is .15 to .95 inches of plant material. 5. Now you have your grow medium and cuttings in sterilized jars with the lids loosely on top. Place the jars approximately 12 inches underneath cool spectrum lighting. The temperature should be kept between 60°F to 75°F. Light cycles can be kept consistent with vegetative plant light cycles (16+ hours of light per day). The area in which you store/grow your clones should have little to no air circulation, as to reduce the risk of contamination. 6. In a very short period of time you will begin to see your plants take shape and begin to resemble adolescent plants as opposed to chunks of plant material. At this point you have a couple options. A. You can continue to grow your plants with the same method, transplanting them into larger containers as needed. Once your plants have quadrupled in size you can actually divide them into pieces and start the process over. B. You can place your plants into soil or a hydroponic growing medium. The key to success in transferring your plants from the micropropagation growing medium to any other growing medium is ensuring that you have removed all of the micropropagation medium prior to transplanting. Also you should treat these small plants with as much care as possible until they have been assimilated to their new environment (placing a humidity tent over them and diffusing their lighting is highly recommended for the first week after transplantation). Again, it cannot be stressed enough that cleanliness and sterility are of utmost importance. From the instruments that you use to the area in which you take the cuttings from your plants, your success will depend on how well you are able to protect these small plants and limit their exposure to contaminants.

pH What to do, what not to do and why “I’m trying to test the pH of my solution to make sure my plants are getting enough nutrients. I think my pH tester is broke. Or maybe it is clogged. I’m not sure, but I’ve only had it a few weeks. I think I need to return it.” –Frustrated Hydroponicist

Troubleshooting Your pH Tester

Chances are the pH tester does not need to be returned. Instead, applying some simple troubleshooting and storage techniques can save the hydroponicist’s time and frustration. Several influences can impact a tester’s functionality, leading to drifting readings, slow response times, environmental interference and more. Here are some common complaints and what to do about them:

120

•

When measuring liquid that is fairly clean, carbon dioxide can cause the pH to change as the sample is allowed to sit and react with the air. This may appear as drift, but actually the CO2 is changing the pH. In general, pH testers containing electrodes with built-in temperature sensors aren’t as responsive as separate pH and temperature electrodes.

“My reading keeps drifting. What can I do?”

“I don’t think my pH tester is working. It’s so slow.”

The types of sensors or electrodes in pH testers are gel-filled.You are most likely to experience drifting when measuring a relatively large volume of liquid, measuring liquid at slightly colder temperatures or testing fairly clean water. Here’s what might be happening: • Because gel-filled electrodes leak solution at a much slower rate than liquid-filled electrodes they take longer to stabilize. This slower response can be perceived as “drift.” • When measuring a 17 ounce sample, your readings will take longer to reach equilibrium (i.e. “drift”) than if you used a smaller volume of three or seven ounces. Try using a smaller sample size.

The age and condition of the electrode in your pH tester can affect response times. Properly functioning, new gelfilled electrodes will go from pH seven to pH four in no more than 60 to 90 seconds. Keep in mind: • As electrodes age, they respond more slowly. • In some circumstances it is normal if your electrode is quick to respond during calibration but slower to respond during your test. • Electrodes that are dirty or dried out will respond sluggishly. If rinsing with clean water isn’t enough, warm, soapy water will work well for most organics, while low concentrations of acids work well for most inorganic material. After cleaning, a period of soaking to rehydrate the glass sensing bulb may be necessary—warm (140 to 176°F) pH four buffer works well and is easy to confirm when hydration is complete as the pH reading will be constant.

“Calibration is necessary to achieve an accurate reading. In a sense, it sets the meter at the correct level, much like a scale needs to be placed at exactly zero to produce an accurate weight.”

“There seems to be interference affecting my readings. What’s happening with my tester?” Be wary of electrical signals introduced into your system such as nearby electric mixers, motors, ballasts, fans, etc. These can create environmental “noise” and impact your readings.

121

Troubleshooting Your pH Tester

“My tester doesn’t seem to be calibrating. What do I do?” Calibration is necessary to achieve an accurate reading. In a sense, it sets the meter at the correct level, much like a scale needs to be placed at exactly zero to produce an accurate weight. To calibrate, always choose a pH seven buffer solution plus at least one other pH value close to your expected measurement range. Using solutions of known pH value allows you to adjust your tester. Perform calibration before each reading or set of readings. To troubleshoot: • Be sure to calibrate with fresh, unexpired buffer solution. • Try changing the batteries and calibrating again. • Reset the tester.

“My pH tester is grimy and not working well. How do I clean it?” pH testers with mechanically intact electrodes containing no broken parts can often be restored to normal performance by one of the following procedures: • General cleaning: Soak the electrode in a 1:10 dilution of household laundry bleach in a 0.1 to 0.5 per cent liquid detergent solution in hot water with vigorous stirring for 15 minutes. Place electrode under warm,

122

“Properly storing pH testers ensures optimal functioning and enhances their longevity.”

•

running tap water for 15 seconds. Soak the electrode in storage solution for at least 10 minutes. Removing saltdDeposits: Dissolve the deposit by immersing the electrode in 0.1 M HCl for five minutes, followed by immersion in 0.1 M NaOH for five minutes, and thorough rinsing with distilled water. Eliminating oil/grease films: Wash electrode pH bulb in mild detergent or methanol. Rinse electrode tip with distilled water. Clogged reference junction: Heat a diluted KCl solution to 140 to 176°F. Place the pH electrode into the heated KCl solution for approximately 10 minutes. Allow the electrode to cool while immersed in unheated KCl solution. Disposing of protein deposits: Dissolve the deposit by immersing the electrode in a one per cent pepsin solution with 0.1 M HCl for five minutes, followed by thorough rinsing with distilled water.

Measuring the pH of Pure Water

Common sense says: “What could possibly be so difficult about reading the pH of pure water? It should be neutral-pH seven, and there are no interferences.” In practice, it can be quite difficult and often frustrating to obtain reproducible pH values in samples with low-ionic strength. Water that has very few ionic species is said to be low in alkalinity, ionic strength, or have low conductivity/high resistivity such as distilled or deionized (DI) water. It is common to attain different pH values with new, sealed electrodes that calibrate perfectly in pH buffers when attempting to measure DI water. This is due to the varying junction potentials that develop across the reference junction. Some techniques and product recommendations for overcoming such limitations will be discussed here.

Other measurement tips: • It is beneficial to measure pH in the smallest sample volume possible. Direct pH measurement in large volume samples such as drums or tanks and other samples with flowing or moving water tend to fluctuate and will require excessive stabilization time. • Addition of a tiny amount of KCl will increase ionic strength to the sample and improve response time. Only high purity KCl should be used as trace contaminants in low-grade KCl can artificially alter the pH. • Maintain good-laboratory practices including using clean glassware, avoiding cross-contamination after calibration by rinsing thoroughly with DI water, using only certified calibration standards, etc. • Temperature compensation should be used during measurement and calibration. Calibrate daily at multiple pH calibration points. • Minimize exposure of your sample with air. CO2 gas absorption can actually decrease pH.

123

Troubleshooting Your pH Tester

“I’m not sure if I’m storing my pH tester correctly.”

For all of these cleaning procedures, soak the electrode in storage solution for at least 10 minutes prior to use. If these steps fail to restore normal electrode response, replace the electrode.

124

Maximum Yield USA | September 2011

Properly storing pH testers ensures optimal functioning and enhances their longevity. However, electrodes should not be stored for longer than six months. After six months, electrodes should be rotated or replaced. For best results, always keep the pH bulb wet, preferably in a storage solution or in pH 4.01 buffer with 1/100 part of saturated potassium chloride (KCl) added. Other pH buffers or tap water are acceptable storage media, but avoid storing in distilled water or reverse osmosis water because it will deplete the hydration layer of refillable electrodes and decrease the life of nonrefillable electrodes. KCl and pH four buffers provide good conditions for mold to grow. To prevent mold from growing in storage solutions, use up

to four per cent of sodium benzoate or azide in the reference fill and storage solutions. If the electrode has not been hydrated (i.e., placed in solution for more than one hour), allow the electrode to soak in a buffer (preferably pH four) prior to standardization or measurement. This will help optimize and reestablish the thin hydration layer on the sensing bulb, which is critical to pH measurement.

The Help Desk If after applying the techniques above your pH tester still seems a bit off, it may be time to call the professionals. Many suppliers and manufacturers have technical experts available to assist you by phone, e-mail or even via live chat on their website.Write down any error messages before you call. Be ready to answer how long the problem has been going on, as well as specifics such as the temperature of the solution. Of course, if the pH tester has any cracks or physical damage, this likely is diminishing its performance. At this point, the technical expert can propose the next best steps. MY

Certain essential plant elements are required for photosynthesis and related metabolic processes. Some have a direct role in the structure of the photosynthetic apparatus. Necrosis and chlorosis (chlorophyll loss), which gives brown or yellow discoloration in the leaf , that accompanies a deficiency of an essential plant nutrient, results in reduced leaf area and plant metabolic activity.

Photosynthesis and Plant Nutrition

Often by the time symptoms are visible in the plant leaf, the metabolic activity in the chloroplast is severe and plant growth has been reduced to a loss for the grower. Essential plant nutrients involved in the translocation of photosynthesis from the site formed (light and dark reactions) to areas of sink formation—fruits, grains and storage organs—are another area where deficiencies of a specific plant nutrient can reduce overall plant growth. The rates of photosynthesis can be reduced significantly if storage sites are not developing properly and acting as a sink for the photosynthate formed in

photosynthesis. Understanding how essential plant nutrients are involved in the photosynthesis process is necessary for the plant nutritionist to maximize plant health and economic growth of the crop. P hotosynthes i s i n gene r al In the most general terms, photosynthesis can be described as the process by which plants use light energy to transform carbon dioxide (CO2) and water (H2O) into oxygen (O2) and carbohydrates. A general reaction for the photosynthetic process is shown below: C O 2 + H 2 O + L i ght E ne r gy - - - > ( C H 2O ) + O 2 Photosynthesis, however, is not that simple. It actually consists of several interconnected processes that work together in taking solar radiation and using it to turn carbon dioxide and water into starches and oxygen gas. Inorganic elements play a vital role in all of the processes of photosynthesis. Nutrients can play both a direct and indirect role in photosynthesis. Direct effects of nutrient deficiencies are usually considered reversible. Elements can be considered to have direct effects on photosynthesis when deficiencies of a particular element can cause a rapid decline in photosynthetic activity; and upon reintroduction of that element at a proper level, photosynthesis resumes. Indirect effects are not usually readily reversible. They occur over a longer period of time and involve an element that is not necessarily critical in the photosynthetic process, but instead is crucial in the production of something that is directly involved. An example of an indirect effect “ W i thout sulfu r , chlo r oplast p r oduct i on would suffe r and photosynthes i s r ates would fall off. “

would be the depletion of sulfur. Although sulfur is not directly involved in the reactions of photosynthesis, it is a major component of amino acids, which make up many of the proteins of the chloroplasts. Without sulfur, chloroplast production would suffer and photosynthesis rates would fall off. Unlike the elements having direct effects on photosynthesis, the reintroduction of elements that indirectly affect the photosynthetic process may not readily improve rates of photosynthesis. Often, the symptoms of many nutrient deficiencies are simply the visual manifestations of decreased photosynthetic activity by a plant. For example, the chlorosis that occurs when plants are deficient in magnesium (Mg) is due to the fact that magnesium makes up part of the chlorophyll molecule. Chlorophyll is a pigment in plants responsible for giving them their green color. Thus, when magnesium is lacking, chlorophyll production is lowered and leaves yellow. In order to understand the role of the essential elements in photosynthesis we must first have an understanding of where, how and why the various processes of photosynthesis occur. P hotosynthes i s i s a se r i es of pa r t i al p r ocesses : 1. Interception of incident radiation and its conversion into chemical energy as NADPH and ATP. 2. Diffusion of CO2 to the chloroplasts. Photosynthesis largely occurs in the leaves of green plants. In particular it occurs within an organelle that is unique to 136

Maximum Yield USA | September 2011

plants called the chloroplast. The chloroplast is one of three general types of plastids. The other two types are called chromoplasts and leucoplasts. Chloroplasts are organelles that are bounded by a double membrane system; which encloses an internal membrane system, the thylakoids, and a gel like matrix called the stroma. Thylakoids are grouped into stack like structures called grana, and several grana can be connected by tube like structures called frets. It is among these structures that photosynthesis occurs. Chloroplasts have also been shown to contain significant concentrations of inorganic nutrient ions. Studies have shown that more than half of the N, Ca and Mg in a plant is in the leaves. Concentrations of Ca, Mn, Fe, Cu, Mg, Al and Si have all been detected in the lamellae of the chloroplasts. When essential elements are deficient or present in toxic amounts, a number of common changes can occur in the chloroplasts of a plant. Often, the chloroplasts of affected plants display the following irregularities: • Chloroplasts are more spherical than ovoid in shape. • The number of grana tends to be reduced or appear as indistinguishable plastids. • Deficiencies in calcium can result in membrane irregularities. • Deficiencies in sulfur can result in general chloroplast irregularities. • Deficiencies in magnesium of iron can result in destruction of lamellar systems as well as irregularities in chloroplast membranes. • Ammonium toxicity can result in a decrease in the number of grana present as well as a general swelling of the chloroplast. This is likely related to the uncoupling effect that ammonia has on photosynthetic phosphorylation. “ T he r eact i on cente r cons i sts of some p r ote i ns and chlo r ophyll molecules that use th i s gathe r ed ene r gy and conve r t i t i nto chem i cal ene r gy. “

3. Synthesis from triosephosphate of starch in the chloroplasts or sucrose in the cytoplasm.

It must be noted that although we have split photosynthesis into several different processes for the purpose of studying it; all of the steps listed are invariably linked together and can all occur at the same time in the plant.

T he L i ght React i on The light reaction of photosynthesis involves the adsorption of light radiation of particular wavelengths and the utilization of this absorbed energy to split water molecules in order to generate ATP and NADPH, which can be used as a source of chemical energy in the dark reaction. The light reaction takes place within two working units called photosystems. Photosystems consist of chlorophyll and other pigment molecules, such as xanthophylls and carotenoids, which absorb light energy from particular wavelengths. The pigments that absorb light energy are called antenna pigments. These pigments absorb light energy and deliver it to an area called the reaction center. The reaction

The various pigments in plants help give them the unique ability to absorb light energy and convert it into useable chemical energy. Though all the pigments play important roles in the functioning of green plants, the one whose role is the most obvious is chlorophyll and thus it will be discussed here. Chlorophyll is a large molecule with a heme structure, much like the hemoglobin in our red blood cells. However, instead of having an iron atom in the center like a nitrogen porphyrin ring hemoglobin does, it has a magnesium atom. There are different types of chlorophyll: chlorophyll a, b and c. Chlorophyll a makes up about 75 per cent of the chlorophyll in a green plant and is thus most essential to the photosynthetic process. What makes chlorophyll so special is its ability to absorb light.

Chlorophyll absorbs some wavelengths of light better than others. It absorbs very little light in the 500 nanometer range of wavelength. Not surprisingly, this corresponds to green light in the electromagnetic spectrum. Chlorophyll best absorbs light from the 680 to 700 nanometer range. This corresponds to red/far red light on the electromagnetic spectrum. Chlorophyll takes the energy it absorbs from these wavelengths of light and converts it to useable chemical energy within the photosystems of the light reaction of photosynthesis. There are two separate photosystems over which the light reaction takes place. Appropriately enough, they are named photosystem I and photosystem II after the order in which they were discovered. One of the main differences between the two photosystems is that antenna pigments of photosystem I absorb light predominately of a wavelength of 700 nanometers while the pigments of photosystem II absorb light mostly from the 680 nanometer wavelength. The two photosystems are joined by an electron transport chain made of a number of proteins, many of which contain inorganic nutrients within them. MY

Tips and Tricks

How to Test pH Levels in

Soil by Therese Cressman

Is your soil acidic? Neutral? Alkaline? Why does it matter? Find out. Most plants need a fairly neutral soil so they can retrieve all the nutrients from it that they require, but some are more fussy and may want a more acidic or alkaline soil. By testing the soil, you can determine if a garden location will be ideal for a new plant or if the soil should be amended first (to adjust the pH level as needed). Many plants thrive in neutral soil (a pH reading of approximately 6.5 to 7.5) but there are some that require a more acidic (below seven) or alkaline soil (above seven). The scale is from zero (most acidic) to 14 (most alkaline).

“Many plants thrive in neutral soil (a pH reading of approximately 6.5 to 7.5) but there are some that require a more acidic (below seven) or alkaline soil (above seven).” Before testing: For an accurate reading use clean tools and remove any debris from the garden surface, then dig down about four inches to retrieve a soil sample. For potted plants, a couple of inches below the surface is fine.

Three ways to test soil: • Use a soil meter, probe or kit:These vary in price and quality. • Quick and dirty DIY test: Not very specific but can give you an idea of what type of soil you’re working with and the testing supplies are likely in your pantry already. • Send out samples:This can be done free or at low cost using local government or horticultural facilities (universities, greenhouses, etc.).

Soil kits, probes and meters There are a few different types you can buy and the kits will come with instructions for using their particular product. Generally a soil test kit is used by pouring a bit of dirt in the supplied tube or container, adding the provided tablet or powder, filling container with water and shaking until the powder or tablet dissolves. After a few minutes the test will display a color that you will compare against the kit’s color chart to see how your soil has tested.

Another option is a soil meter or probe that is either inserted directly into the ground or in a water and soil slurry mix. These can provide near instant readings and display either a color code or number to indicate the soil content.

Quick and dirty test This won’t give you a specific reading, but it can give you an idea whether or not your soil is acidic or alkaline. • Vinegar test:Take a sample of dry soil (about ¼ cup), mix with distilled water to make a liquid mud and then start pouring household vinegar over top.

If the mixture fizzes, the soil is alkaline. • Baking soda test: Mix dry soil and distilled water as above then start sprinkling baking soda over top. If the mixture bubbles, the soil is acidic. • If neither test produces a reaction, you have fairly neutral soil. Do you remember way back in the day when Grandpa would grab a handful of dirt on the farm and smell or taste it? It was the old-timer’s method of determining the pH level of the soil…if it tasted or smelled sour the soil was acidic and he knew then that it was time to add lime to increase the pH. If it tasted or smelled sweet that told him the soil was more alkaline.

with your local government agricultural office or university’s horticultural department. They’ll do the soil analysis or advise where local gardeners can get their soil samples tested.

Quick tips for amending soil • For more acidity (sourness) try adding sulfur, pine needles or cottonseed meal to lower soil pH. • For more alkaline (sweetness) try Send out samples adding lime or wood ash to increase If it’s imperative that you know soil pH.

Beat the Heat

Depending on where you live and how extreme the seasonal variations in your area, the warmer months of the year may tend to defeat many of the techniques you’ve been using in order to harvest top-shelf indoor crops. In the summertime, indoor farming efficiency has a tendency to plummet unless the grower is prepared in advance to skillfully execute certain environmental control precautions. Pest populations may produce twice as fast in the summer months due to constant high temperatures and the excessive heat may hinder plant growth as well, leaving gardens vulnerable to pest infestation, drought and molds. Root diseases such as pythium are also at a power play advantage,

as increasing reservoir temperatures from the extreme heat decrease available dissolved oxygen to the feeder roots on the plant.This can suffocate plants, resulting in almost immediate death with little time available to try to save or recover the victims.This is not to say that indoor gardening is impossible during the summer months in places like Arizona, Colorado,Texas or Southern California, however; in fact, some of the warmest parts of the country are home to growers who boast premium-quality indoor-grown produce all year round. Last month’s discussion provided some essential techniques to help you achieve a bumper outdoor-grown harvest during the peak growing season.After all, the sun is the greatest free resource an outdoor

gardener can have. If at all possible, you should try starting a garden outside during the warm summer months—whether it is hydroponics-based or soil-grown organically, it’s a great way to increase your skill and knowledge about plants in general and it can only make you a better indoor grower. High temperatures are your worst enemy in the summer season if you’re an indoor grower.Although your HID lighting (sodium and halide) can tend to raise temperatures in your indoor grow space to untenable levels during the summer months, proper air cooling of six inch and eight inch reflectors with high velocity fans can promote easier control of your environment, in conjunction with A/C and water chilling devices if required.

For many growers, air conditioning is an essential element in the climate control properties of their room design in the summer months in arid climates such as Arizona or Colorado—upwards of five tons (60,000 BTU) and more of A/C is not uncommon for commercial growers housing multiple sets of lights in areas as large as 2,000 square feet, especially when temperatures outside are upwards of 95°F! When the sun is this hot throughout the day, 1,000 watt lights are the last thing a grower wants to have boosting the temperature without the safety valve of a high-efficiency air conditioner or watercooled air handler. Split units are also a great way to provide cool, fresh air intake to the garden while isolating the heat from the compressor. Portable A/C units are a “High temperatures are quick fix for spot-cooling treatments in your worst enemy in the gardens, but will probably require more summer season if you’re than 14,000 BTUs in order to handle an indoor grower.” gardens housing more than two 1,000 watt lights.Water chilling air handlers are advantageous for cooling purposes, but can result in excessive humidity levels caused by condensation.Water chillers may seem kind of expensive initially, but for hydroponic applications in particular these devices will ensure steady growth even in the hottest grow room environments—instances

where rooms upwards of 100 degrees will still maintain inches of plant growth per day in continually running systems using 60 to 65 degree chilled water are not unheard of. Dimmable electronic and digital ballasts have proven to be advantageous from both an energy efficiency and environmental control standpoint. Having the ability to reduce the energy consumption and light output of 1,000 watt lamps, or, in some instances, having the luxury of being able to replace them with 600 or 750 watt lamps is a good example of a recent technological breakthrough in horticulture that can improve production for the grower. Implementation of dimming functions on electronic and digital ballasts has proven to be a versatile solution for controlling temperature issues in the garden—growers are now able to maintain adequate production and photosynthesis with 1,000 watt lights, while without a dimmable option these lights would have to be turned off in order to keep the room temperature down. Obviously there is no benefit to plants to be derived from a 1,000 watt light—or any light at all—if you can’t control the temperature during the sweltering summer months. Problems stemming from the excessive heat and energy sometimes generated by conventional indoor light sources have started to steer growers towards LEDs as an alternative.They are not necessarily a perfect solution, however, although they are continuing to gain in popularity as the technology matures, and more and more interested growers are making the investment to see what this new-age lighting is capable of. Canister-style designs, intense spectral emitters no bigger than a coke can, have proven to be useful as supplemental light sources to sodium or halide reflectors, penetrating the plant canopy with less

heat and kilowatt consumption than HID bulbs. Patented LED chips are specifically engineered for different stages of growth and are advertised to never deteriorate in output for up to seven years, eliminating costly lamp replacements for those who replace their bulbs on an annual or even more frequent basis.Although many growers may find that LED technology alone will not yield the results normally produced by sodium and halide bulbs, they will enjoy a drastic reduction in overhead operating costs.The ability to maintain a productive garden without the need for A/C, expensive inline fans and costly energy bills does seem to more than pay for itself during the summer months, when many experience downtime in the form of seasonal problems like insects, molds, rots and temperature issues.

Beat the Heat

Commercial growers using multiple banks or runs of lights in industrial spaces often experience the reality of summer in its harshest form. Insulation is usually poor, making cooling and heating large growing areas difficult. If possible, you should frame out smaller individual rooms from larger spaces and try to contain lights within each area. For example, instead of one room with 60 lights, you might have six smaller rooms framed out with 10 lights in each room.This method will also help to quarantine each growing space and prevent transferring infectious pathogens, bugs and mildews. In the event that all the lights are situated in a single area for flowering and fruiting cycles, coordinate the multiple banks to stagger the lights on in sections, alternating sections in specific intervals. For example, if you have two rows of 20 lights, then starting at one end of the two rows, four lights—or two lights per row—may kick on for two hours.After two hours of operation the next bank of four lights will start a two hour cycle, and so on.Although it may cut production to some extent on most indoor-cultivated fruit and flower varieties, this technique is an energy-efficient alternative that reduces the heat in the room and maintains enough light for consistent production despite the summer heat outside.Another common sense suggestion is to always operate your garden with lights on during the night and lights off during the day if possible, providing more control over your indoor environment since the heat emitted from the lights will not be in conjunction with the heat from the midday sun. Soon the summer will draw to a close and outdoor growers will prepare for a heavy harvest to end the season and begin sowing or cloning for the indoor one yet to come. For many, the new fall season will mean a drastic reduction in temperatures, allowing growers to expand operations and turn on more lights. MY

YOU TELL US

A Maximum Yield exclusive interview with DL Wholesale owners and founders Darren Lacativo and Donald LaRosa revealed the reasons growers love their Bake Bags, how Panda Film improves lighting efficiency and why heat mats are beneficial for indoor gardeners.

Darren Lacativo and Donald LaRosa

Maximum Yield (MY): What products in the DL Wholesale line are you most excited about right now? Darren Lacativo and Donald LaRosa: Our most exciting product right now is our new line of Oasis Grow Tents.These tents are truly amazing and have countless useful features that other tents on the market don’t have. For example, our tents don’t use any Velcro. Instead we have high-quality, airtight, waterproof and lighttight zippers on all doors, windows and even vents.That feature, along with our clear plastic windows, allows growers to maintain the most consistent plant environment while still being able to visually check on their products. Each opening also uses one full zipper, so you can unzip your openings in one fluid motion. And we don’t make our customers waste time rolling up all the tent flaps; instead we designed it so you can let them hang and they won’t cover or interfere with any neighboring vents or drag on the ground.We 158

Maximum Yield USA | September 2011

also provide the perfect number of ducting and electrical openings in each tent that use drawstrings on both the inside and outside of the tent, which gives you the most airtight connection and makes them adjustable. Oasis tents are also seven feet tall, come in four sizes (which will fit all major band trays) and feature an accessory pouch on the outside. MY: What’s with the oven bag trend that has swamped our industry? Why should growers choose your “Bake Bags” version? Darren and Donald: Oven Bags were originally designed for the kitchen and are still used there as an alternative method of cooking meat and poultry in the oven, mostly turkeys. They have recently become extremely popular in the hydroponics industry because growers have discovered that these bags also work great for garden storage of things like vegetables, herbs and even soil in some cases. Because the bags were originally designed to go in the oven, they are extremely durable, heat resistant and they can hold a lot of weight. All of those features also make them great for our customers. Our Bake Bags are special because we took the features that growers love—thickness and strength— and enhanced them so that they work even better for our customers. We also increased the size of our bags to 19 by 23.5 inches so we have the largest and thickest bags on the market. MY: What is Panda Film and how does it improve lighting efficiency? Darren and Donald: Panda Film is a thick poly film that can be used to reflect light back onto the growing area, allowing growers to take full advantage of all the lumens they are putting out, improving lighting efficiency. Unlike regular Mylar, Panda Film is completely opaque so light will not seep through. It uses a white surface to reflect light and heat, instead of silver, which only reflects light and will actually absorb heat. It’s also thicker, stronger and easier to clean than traditional Mylar. MY: Explain how heat mats work and why they are beneficial for indoor growers? Darren and Donald: Temperature is a major factor in how fast a seed or cutting will germinate because it affects growth on the

cellular level. Each species of seed has an optimal temperature at which it will germinate the fastest, and heat mats are one of the best ways of controlling the temperature of your seedling’s environment. They are especially beneficial to indoor growers because temperature control and lack of space are usually two of the most important things to these growers, and our Root Radiance Heat Mats are the perfect solution. It doesn’t hurt that they’re priced competitively either. MY: What can Maximum Yield readers expect from DL Wholesale in the near future? Darren and Donald: In the near future you can expect that we will more than double the size of our catalog, again, within the next year, and you can expect our prices to stay competitive. We are also trying to increase the manufacturing of our products within the US whenever possible, so stay on the look out for those little American flags on our products. We are also planning to open a new distribution warehouse on the East Coast so we can offer those customers the same great service and shipping rates that we currently offer our customers closer to us on the West Coast. And you can also expect to see a new electronic ballast from us that will be an industry changer, and we are very excited about it! We are currently in development now, and you can check our website and blog for updates.

warehouse lighting to more efficient and eco-friendly compact fluorescent bulbs. We also use electronic invoices and other paperwork whenever possible in order to reduce paper waste, and we utilize recycled corrugated packaging for many of our products. MY: Where can growers go for educational materials on using your products and to learn more about your company? Darren and Donald: You can learn more about our company and our products on our website www.dlwholesale.com and our blog, located within our website. In terms of educational materials on using our products, we are currently working on developing our own information videos, but in the mean time there are countless articles and videos all over the Internet, especially www.maximumyield.com and YouTube, that address just that. We also do everything we can to support unbiased industry professionals who create informational videos and reviews by supplying them with products. MY

MY: How does DL Wholesale support local causes and community building? Darren and Donald: Since we are still a start up in our second year of business, it can be difficult to find the resources to support and build up the causes that we care about, but we donate to associations like the California Environmental Project and Ride Ataxia, as often as we can. MY: What strategies has DL implemented to lessen their environmental impact on our planet? Darren and Donald: We are always brainstorming new ways to reduce our carbon footprint and help the environment. We are currently switching out all of our Maximum Yield USA | September 2011
