from the EDITOR TG Toby Gorman

Maximum Yield

inally, it’s March. The long, dark nights of winter are giving way to longer days, and the energy from the sun strengthens, giving all that bask in its rays that welcome, rejuvenating energy. The anticipation of another season of growing is at its height. For the modern grower, March is the time to take stock of what is needed for the upcoming growing season, plan a strategy, and get your seedlings off to a strong start by starting them indoors. As Monica Mansfield states in her article “Off to an Early Start: Starting Seeds Indoors” on page 40, this is the time to get your garden underway by starting your seeds indoors. The benefits of this practise are numerous: It’s less expensive, there are more varieties to choose from, the plants are safe from the elements, and there is always the satisfaction of noticing when that little seedling has poked through the soil. “The process is simple, but it can be somewhat of an art and it pays to learn

from others’ experiences,” says Monica, who provides all the information you need to set your plants and yourself up for success before taking them outside. To complement that story, in this issue you’ll also find Grubbycup’s article “Caring for Delicate Pre-veg Seedlings” on page 50. In this article, Grubbycup takes us inside the seed and provides us with all we need to know to ensure our seeds survive. “Seedlings can wither and die in a matter of hours without proper moisture,” he says. “They don’t have an extensive enough root system to reach very far within the growing medium to take advantage of large containers, and as such are frequently started in smaller containers, then transplanted as they increase in size.” The success of your garden in late summer or early fall depends on the foundation you create now. All of that hard work you put into your garden in the coming months will pay off by getting your seeds off to a strong start.

GRAFTING

Grafting is the act of taking a bud, shoot, or scion of a plant and inserting it into

a groove, slit, or surface opening in a stem or stalk of another plant in which it will continue to grow symbiotically. Grafting has been practiced for thousands of years. Grafting has many purposes, from protection against diease to the creation of new fruit vareties. Grape varietals are often grafted onto different root stock to provide protection from disease and in-soil threats like fungi that one species might be adapted to, but the desired fruit crop is not. Some grafts are within families such as apples, while some are more exciting. For example, tomatoes can be grafted onto potato plants to create a more productive garden plot. Grafting can only be successful if the grower manages to put the vascular tissues of the scion and the rootstock into contact with one another.

ask a GROWER Q

Quick question on solar. I want to run eight, 1,000W adjustable double-ended bulbs along with a five-ton AC unit and a Quest 205 dehumidifier. Along with fans, lights and AC on 240V, and the rest 120V. On an average of 18 hours a day. Around 150 amps to be safe. Is that a sufficient amount of info to receive an idea on what type of solar kit I can buy? Thank You Hello, For most people, the main purpose of going solar is to offset the cost of electricity. However, solar power systems come in two general types, grid-tied and off-grid. This is generally one of the first decisions to make when it comes to solar panel installation. Grid-tied means that the solar panels are directly tied to the conventional power grid and may provide some or all of your power needs. When unused power is created by your solar panels it is automatically delivered to the grid, earning you credits on your power bill. Off-grid systems are not connected to the conventional power grid and operate independent of your local power company, and requires that 100 per cent of your power comes from your system. Also, unused power must be stored in a battery bank until it can be used at a later time. A truly off-grid system will greatly increase the cost per watt of your solar system and also cost more to maintain over time. I will assume you are most interested in a grid-tied system. Because of the sensitive nature of the equipment, I would recommend having a licensed electrician pull four circuits from your supply of power. Subpanel No.1 will be for the eight lighting fixtures. Each doubleended fixture is capable of 1,150 watts, so we will estimate maximum power consumption at 9,200 watts. At 240V the total draw is approximately 38.3 amps (38.3A). For safety and load ratings I always add 20 per cent which makes the correct choice for Subpanel No. 1 a 50A double pole 240V breaker.

Subpanel No. 2 will be for the five-ton commercial grade A/C which will use about 32A or less at 240V, so that makes the correct choice for Subpanel 2 a 40A double pole 240V breaker. Subpanel No. 3 is for the commercial-grade 205-pint dehumidifier that will require a dedicated 120V 20-amp circuit with a NEMA 5-20 plug. Lastly, I would have your electrician pull a final 120V 15-amp circuit for all of your additional fans and accessories. The total wattage of the major appliances is around 18,325 watts. Assuming all the major appliances are running at maximum for 18 hours a day, that is approximately 330 kilowatt hours (kWh) per day, or 10,030 kWh per month. However, although the lights will operate for 18 hours a day continually, the A/C and dehumidifier will not, so your actual consumption will be less. Because of the complexity when it comes to selecting the right size solar system, I would recommend you to consult a local company to determine the number of solar panels you will need. Local factors such as geographic location, weather, positioning, and line of sight blockages in your horizon all play a factor into how many kilowatt hours you can produce per day. Also, local laws, permits, and regulations will apply, which makes consulting a local solar expert worth the time and money to insure a smooth purchase and installation. Scott Wakeham

max FACTS Weed-eating Ants Could Be Boon for Farmers

Research suggests harvester ants, which eat weed seeds, can help farmers manage weeds in their fields. Farmers can also save water and improve soil quality through less tilling, which preserves the ants. “These ants are naturally present in the fields,” says Barbara Baraibar Padro, a postdoctoral scholar in plant science from Penn State. “They are able to remove a huge amount of weed seeds from the system, and if farms till less to preserve ants, it can benefit them.” The research, conducted in Spain, and published in Biological Control, shows non-tilled fields had larger nests, leading to better weed management. Tilling less can help farmers save water, improve their soil, reduce the costs of fuel and labor, and help the ants that consume weed seeds. Harvester ants can also help farmers manage herbicide-resistant weed species such as rigid ryegrass. — sciencedaily.com

Black Apples: Rare and Costly

When people think of apples they think of vivid reds, greens, yellows or a mixture of the three colors, but they can grow dark purple, almost black, as well. These rare apples are called Black Diamond and are only grown in the mountains of Tibet. They cost $7.26 per fruit and are sold in high-end Chinese supermarkets in packs of six to eight. Black Diamond apples are a breed of Chinese Red Delicious that get their plum-like dark purple color from the geographical conditions of Nyingchi, in the Tibet Autonomous Region of China. A Chinese company has set up a 123-acre orchard at an elevation of 10,170 feet above sea level. The reason these apples turn dark is the notable night and day temperature differences, and their exposure to intense sunlight and ultraviolet light which causes their skin to go from the characteristic deep red to dark purple. — freshplaza.com

Pesticide Laws Need to Protect All Bee Species

New reports argue pesticide regulations designed to protect honeybees fail to account for potential threats from agrochemicals to the full range of bee species. With the human population on the rise, and as pollinators continue to suffer declines caused by everything from habitat loss to pathogens, regulators need to widen pesticide risk assessments to protect not just honeybees, but other species from bumblebees to solitary bees, says environmental sciences professor Nigel Raine, holder of the Rebanks Family Chair in Pollinator Conservation. “There is evidence that our dependency on insect-pollinated crops is increasing and will continue to do so as the global population rises,” says Raine, who co-authored three papers recently published in the journal Environmental Entomology. Government regulators worldwide currently use honeybees as the model species for assessing pesticide exposure to insect pollinators. The papers call on regulators to look for additional models among solitary bees and bumblebees to better gauge health risks and improve protection for those species. — sciencedaily.com

max FACTS The Five Healthiest Leafy Greens

Most know leafy greens are good to grow and good for you as well, but which are the healthiest? Kale is number one due to its many vitamins, minerals, and antioxidants. To benefit from all its properties it’s best to eat it raw as cooking can reduce its nutrient profile. Second best are microgreens, which can contain up to 40 times more nutrients than their mature counterparts, including vitamins C, E, and K. Collard greens come in at number three and they are a great source of calcium as well as vitamins A, B9, and C. They are also one of the best sources for vitamin K. Ranking fourth is spinach, which is another fantastic source of vitamins A, K, and manganese. Cabbage is fifth thanks to its overall nutrient value, plus studies on animals have shown it protects against lung and esophageal cancer. — healthline.com

European Wheat Not Resilient to Changing Climate

With the global climate not only warming but becoming more variable and extreme, food security can be undermined by unpredictable weather. According to research published in the Proceedings of the National Academy of Sciences, Europe’s wheat cultivars are not resilient enough to the evolving climate. The response diversity of wheat on farmers’ fields in most European countries has worsened in the past five to 15 years, depending on the country. The research predicts greater variability and extremeness of local weather conditions will lead to reduced yields in wheat and increased yield variability. Of note is how badly wheat does under heavy rain conditions. Wheat yield is generally sensitive to even a few days of exposure to waterlogging and to wet weather that favors disease. In addition, heat stress rather than drought sensitivity appears to be a limiting factor for adaptation of wheat to climate change in Europe. — sciencedaily.com

Massive Mushroom Considered Largest Organism on Earth A mega honey mushroom, thought to be one of the biggest living organisms on Earth, is much larger and much older than scientists first thought. First studied in 1992 in a Michigan forest, the massive mushroom, first thought to be 1,500 years old, is in fact closer to 2,500 years old and weighs more than 440 tons. Amazingly, it stretches across 70 hectares. The honey mushroom, which largely consists of an underground network of tendrils wrapped around tree roots, is heavier than three blue whales. While the Michigan fungus is large, it is outclassed by another honey mushroom from Oregon that is even bigger. There is also the Pando aspen in Utah, a forest originating from a single underground parent clone that is thought to weigh up to 6.6 tons. The honey mushroom is edible but isn’t among the most flavorful fungi out there. — independent.co.uk

Meet the New American Farmer

More and more these days, people want to know where their food is coming from and the agricultural industry is responding. The number of farmers markets in the US has skyrocketed in recent years and it’s the new American farmer spurring the growth. It’s a term used by Andrew Flachs, an environmental anthropologist at Purdue University, to describe a movement of younger people in agriculture who do it for different reasons than the traditional farmer. Flachs says they are motivated through higher education, personal politics, disenchantment with urban life, or in search of an authentic rural identity. Flachs’s research shows newer farmers appear to thrive on the outskirts of cities that provide high demand and purchasing power, a large population, and a healthy number of farmers markets. New American farmers occupy an important intersection of niche marketing strategies, environmental politics, and rural demographic change that could have a significant impact on food production and social life in agrarian landscapes.

How Robotics Will Influence Agriculture in 2019

More and more, farmers and cultivators are turning to technology to help maintain crop health and production. In 2019, robots, or agribots as they are sometimes called, will have more influence on the industry. Robots will help address the problem of a dwindling workforce while allowing farmers to work more efficiently. Harvest CROO Robotics develops crop-harvesting robots which have a workload capacity equivalent to 30 human workers. And despite fears robots are taking jobs, one agricultural researcher says that’s not true. “The jobs have already been lost. What we’re trying to actually do is increase the skill level that farm workers will have, where they’ll become a fleet manager overseeing the autonomous vehicles,” says Jonathan Gill. Soon, robots will be able to detect plant disease, saving farmers money. Using automation also gives growers more time to focus on the business of farming.

Accelerator

CANNABOOST is an accelerator designed to increase the uptake of nutrients by boosting a plant’s metabolism, essentially stimulating the development of new flowers. It also has secondary benefits including better immune response, faster finishing, and increased quality and taste. Increasing the speed of photosynthesis greatly increases the sugar production in the fruits. This makes for a sweeter taste, while the natural flavors in the fruits will be produced in higher concentrations. It’s suitable for every type of substrate.

Pruning Container

Hydrofarm now offers RediRoot Plastic AirPruning containers. The slatted design reduces and often eliminates circling roots, while providing an ideal environment for airroot pruning to occur. Airroot pruning is a process where a plant’s roots are pruned as they grow rather than when they are transplanted. When a root tip contacts the air, it sends a signal to the plant to produce more lateral roots, creating a dense, fibrous root structure. RediRoot’s design features raised feet for 360-degree aeration, allowing your medium to dry evenly, reducing the possibility of wet spots and root rot.

ragrant, zingy, and an essential culinary ingredient, citrus is not a crop to be left out of the hydroponic realm. While we may be more used to thinking of expansive orchards of spreading citrus trees grown in sun-drenched climates, with a little modification citrus can be a valuable and productive specimen for the indoor garden. By selecting high quality, grafted, and dwarf varieties of citrus, a thriving crop can be grown all year indoors, avoiding the limitations of cold outdoor environments and the risk of frost damage. As an added bonus, citrus flowers are highly fragrant and the glossy, deep-green leaves make an attractive display within any hydroponic system.

Citrus Types

Often overlooked in hydroponic growing, many citrus varieties make for excellent indoor growing cultivars and reward horticulturists with some tasty fruits and fragrances.

While a wide range of citrus is grown commercially using hydroponic methods, these are largely long-term outdoor systems with drip irrigation. Some citrus such as Makrut lime (also called k-lime), grown largely for its fragrant leaves, are produced in greenhouses where heating is applied to extend the harvest season. With a smaller indoor garden, the objective is to maximize yields and fruit quality, while at the same time growing a healthy and attractive tree. To achieve this, investing in dwarf, grafted trees of known cultivars is the best option, as although citrus can be grown from seed, the characteristics of the resulting tree are highly unpredictable. The time to first flowering is often many years and fruit is generally inferior and lower yielding than that of named varieties on grafted plants. There are even some types of grafted trees with two or three different types of citrus grafted onto the one root stock, making more efficient use of valuable growing space. Grafting tends to produce superior trees and crops as the root stock provides additional vigor and disease resistance. Citrus trees are great specimens for restricted spaces as many varieties, such as lemons and limes, tend to fruit relatively young and while still quite small in stature. They can also be pruned and trimmed to restrain excessive vegetative growth and kept compact, while at the same time, still be highly productive. If grown with a restricted root zone volume in limited-sized pots, the height and spread of the tree can be minimized and citrus can even be grown as fruiting bonsai specimens.

Hydroponic Citrus Varieties

The most commonly grown citrus for hydroponic production are the smaller types of lemons and limes; however, there are some more unusual citrus types which offer a unique opportunity to grow a tree crop indoors. These include the tiny-fruited orange kumquat, the limequat, the Australian finger lime (Citrus australasica), blood limes, the strangely shaped Buddhaâ&#x20AC;&#x2122;s hand citrus, and the uniquely flavored calamansi. The Australian finger lime, often called citrus caviar, is a relatively new specimen on the culinary scene which is currently being prized by chefs worldwide and one which is likely to become a valuable commercial hydroponic crop. Finger limes are a relative of citrus, native to Australia, but available from some citrus nurseries in the US. The fruit are elongated and finger like, and are split open to reveal rounded lime green, tart, and juicy vesicles which resemble caviar. Finger limes require warm growing conditions and are frost sensitive outdoors, thus well suited to the year-round protected climate of an indoor garden. Maximum Yield

Opposite page top right: The uniquely shaped `double’ leaves of the Makrut lime are used in Asian dishes. Middle: Citrus flowers are attractive and highly fragrant. Bottom: Citrus often set many more fruitlets than can be carried to maturity.

For hydroponic production, suitable varieties of common citrus types include Meyer and Yen Ben lemons, Tahiti, Key and Mexican limes, mandarins, and sweet Washington navel oranges. Makrut lime is another small citrus tree ideally suited for indoor hydroponic production which produces a double crop of highly fragrant leaves which are finely sliced and used in Thai and other Asian dishes as well as small, knobbly green fruit which provide aromatic zest and juice. The advantage of Makrut lime is not only that the fresh leaves are far superior to the dried version, but the plant is often only grown for its valuable foliage and doesn’t necessarily need to flower and set fruit.

Start with Plants from a Good Nursery

For a new hydroponic planting, obtaining relatively young plants from a reputable nursery is a good place to start as these can then be regularly pruned to maintain a compact and attractive shape before flower buds start to form. Obtaining older, tall and sometimes straggly plants makes the process of height control much more difficult and productivity often suffers with this type of planting stock. Once plants are in place and well established, citrus should be pruned to remove the growing points of any dominant stems and promote the production of several side branches which will allow the plant to carry more fruit and remain compact. 30

Maximum Yield

Light, Nutrients, and Pots

Citrus, being fruiting plants, require a moderately high level of light to keep plants compact, prevent elongated growth, and produce sufficient assimilate (sugars) for high-quality fruit. A light level similar to that provided for fruiting tomato and capsicum plants is ideal, provided citrus trees are not overcrowded and kept pruned for maximum light interception. If light levels are low, citrus trees will continue to grow foliage, but often fail to flower or any sparse flowers that do open may not carry fruitlets through to maturity. Temperature optimums are also similar to many other hydroponic fruiting crops, although they vary depending on the type of citrus being grown. For optimal year-round growth, most citrus grows well within a temperature range of 75-86°F, however, will survive much cooler conditions down to 35°F for short periods of time. Since most citrus fruits are a long-term crop and will continue to be productive for many years, growing containers of at least four gallons are recommended. Substrates such as coconut fiber or perlite are ideal, however, citrus have been grown on a wide range of soilless mediums including gravel, grow rocks, peat, bark, stonewool, rice hull, and even in aeroponics. Good drainage is essential with citrus as oversaturated root zones can be prone to root rot, so the addition of some coarser material in the base of the growing container is always a good

idea for long-term plants. Drip irrigation systems are most often utilized for nutrient delivery with standard vegetative and fruiting formulation applied during the different stages of citrus tree growth. A nutrient formation high in potassium with additional magnesium is essential during the fruit formation phase, as citrus fruit quality is related to potassium nutrition as well as environmental growing conditions.

Tips for Indoor Cultivation

Apart from good light and sufficient warmth, citrus benefit from some gentle air flow through the foliage. This helps remove any stale air and excess humidity and reduces the disease risk to the plants. One of the most vital aspects of growing fruiting citrus indoors is pollination which is essential for fruit set. Outdoors, bees and other insects carry out the pollen transfer role with great efficiency, however, indoors this needs to be done manually. The process is relatively simple as citrus don’t need to be cross pollinated. A small paint brush can be used to collect the yellow pollen grains from within a citrus flower; these are then brushed off into the stigma (found at the top of the long column in the middle of the flower). The stigma becomes sticky when receptive to pollen, allowing the brushed-on pollen grains to adhere and stay in place. This process can be carried out a few times a week when citrus trees are in flower and is usually highly successful.

It is normal for many types of citrus to produce masses of highly fragrant flowers, far more than the tree could ever support as fruit. For this reason, it’s not usual to see the excess flowers or tiny fruitlets drop from the tree — this is just a natural self-pruning process which thins fruit to only those which the tree can support through to maturity. Young trees may only be able to carry a small handful of fruit in the first season and fruit loading will increase with the age and size of the tree.

Harvesting Hydroponic Citrus

Harvesting citrus fruit is relatively simple — it’s best to cut these from the tree rather then pull them off as this often snaps branches or causes fruit damage. Lemons and limes, once mature, can be left on the tree for a considerable length of time, often months, before harvest and this is often used as a way to store excess fruit until it’s required. However, retaining a high fruit load can delay flowering and the next crop of young fruit, so prompt removal is often a better option. Excess citrus fruit and even k-lime leaves can be stored in the freezer until required or processed into juice, jellies, marmalade, or syrups. Whether it’s the new and exotic Australian finger lime or a common everyday lemon tree, hydroponic citrus fruits are a valuable addition to any indoor garden. Fragrant flowers, glossy deep green foliage, and bright decorative fruit make these ideal productive specimens well suited to hydroponic systems. 32

eliberately shading a greenhouse to control the photoperiod is a gardening technique known as light deprivation. Many plant varieties won’t fruit or flower until the daylight hours are reduced past a certain point. Light deprivation enables a horticulturist to limit the amount of sunlight hours per day to initiate a crop’s flowering cycle. This technique gives a grower heightened control over the photoperiod and allows him or her to bring plants to maturity earlier than they would naturally. Most light deprivation greenhouses have a transparent material (glazing) that is identical to any other greenhouse. Unlike typical shade cloths, which only reduce the amount of light entering the greenhouse, the shade material (also called blackout material) used for light deprivation is designed to keep out as much light as possible. To make the interior of the greenhouse as dark as possible, the shading material used for light deprivation needs to cover the entire greenhouse structure. Each day the shade cover is removed for the desired number of light hours, then manually or automatically positioned back over the greenhouse.

Advantages of Light Deprivation

The advantages of using light deprivation include more control over when to harvest, multiple harvests per year, increased overall yields, and reduced risk.

When to Harvest

A light deprivation greenhouse allows a gardener to control when the flowering stage is initiated and, in turn, when to harvest. This could be advantageous for many reasons, including the ability to harvest the crop at a time of year when other growers still have plants in the ground. That means a higher price for the product and a higher return on investment for the grower.

Multiple Harvests Per Year

The light deprivation method gives the ability to harvest several times per year, much like an indoor garden. If a horticulturist could do the vegetative growth in another greenhouse or indoor garden, he or she could potentially reap as many as four or five harvests per year.

Increased Overall Yields

Although the individual harvests of a light deprivation greenhouse are smaller than a typical outdoor harvest, the overall yield for the season will end up being comparable or even larger.

Maximum Yield

“The advantages of using light deprivation INCLUDE MORE CONTROL OVER WHEN TO HARVEST, MULTIPLE HARVESTS PER YEAR,

increased overall yields, and reduced risk.”

That’s because some of the plants are flowering under the mid-summer sun, so they get stronger, more direct sunlight with a higher level of UV light.

Reduced Risk

By breaking up the outdoor season into multiple harvests, a horticulturist reduces the chance of complete failure. Because of multiple harvests in a light deprivation greenhouse, the grower will not experience a complete loss if one crop is ruined. In other words, if an entire crop is destroyed, the grower will still have other crops to help negate losses. It isn’t an all-or-nothing situation.

Cooling a Light Deprivation Greenhouse During the Light Hours

Controlling the temperature of a light deprivation greenhouse can be tricky. These greenhouses are closed tight during the peak heat of summer, so overheating is possible. The following are some cooling techniques to follow only when the crops are exposed to light. These techniques don’t apply during the dark cycle because they could create a light leak.

can be tricky.â&#x20AC;?

Convection

Convection is the physical movement of a warm gas or liquid to a colder location. Some growers rely on convection to help cool their greenhouses. Strategically placed vents in a greenhouse allow hot air to escape from the top, while cool air replaces it, entering from the lower portion of the greenhouse. This cooling method can only be used in a light deprivation greenhouse during the light cycle. Once the dark cycle begins, the vents need to be closed or covered to ensure no light leaks occur.

Evaporative Coolers

Evaporative coolers work well to cool down smaller light deprivation greenhouses during the light period. They draw air over a wet pad to create an evaporative cooling effect. Most evaporative coolers come with a float valve and are connected to a water spigot so water can be replenished as it evaporates. Evaporative coolers work best when they have access to fresh air, so they should be placed near the greenhouse entry or a fresh air intake vent. If the vent intake is not a light trap, the vent will need to be covered during the dark cycle.

Cooling a Light Deprivation Greenhouse During Dark Hours

The most popular and most effective way to cool a light deprivation greenhouse during the dark cycle is to use motorized fans in conjunction with light traps.

Motorized Fans

The best way to cool most greenhouses is with a motorized fan. A fan in a greenhouse pulls fresh, cooler air through the greenhouse (around the plants) and then exhausts the warm air outside of the structure. Actively drawing cooler air from outside the greenhouse brings the temperature down within the greenhouse. In fact, a powered ventilation system will typically keep a greenhouse’s temperature about 10-15 degrees cooler than if the greenhouse is passively cooled. If a fan system is to work during the dark cycle, it must be used in conjunction with a light trap.

Light Traps

A light trap, also known as a breathable wall, is a bent finned device allowing airflow while blocking all light. Essentially, the wavy fin design of light traps blocks light rays from entering the garden, but still allows for sufficient airflow between the fins, allowing horticulturists to maintain a well-ventilated environment in blacked out conditions. Light traps are a perfect fit for light deprivation greenhouses. They are typically used in conjunction with an intake or exhaust fan, or both. The light trap blocks the light but needs a motorized fan or other device to actively move the air. Light traps can be installed on one or more sides of the greenhouse. Much like an indoor garden, having both an intake and exhaust vent will create the most efficient flow of air. Both the intake port and exhaust port on a light deprivation greenhouse should be equipped with light traps. This enables the ventilation system to operate 24 hours a day, regardless of whether it is during the light or dark cycle. Without light traps, it is difficult to properly ventilate a light deprivation greenhouse and not disrupt the dark cycle.

Shade Material

The shade material, or blackout material, used in light deprivation greenhouses can influence the temperature of the greenhouse itself. A shade cloth that has a white or reflective exterior can reflect a good amount of solar energy, thus reducing the temperature when compared with an all-black or dark colored shade material. Choosing the right shade material can significantly help with cooling.

Maximum Yield

Air Circulation

Air circulation, or air movement, within a light deprivation greenhouse serves many purposes. Oscillating fans are the go-to device for creating air movement within an indoor garden or greenhouse. There are many benefits to proper air circulation, including uniformity of temperature, humidity, and CO2 within the environment. Plants respond well to environmental consistency and proper air circulation ensures each plant within the greenhouse receives the same atmospheric conditions. Proper air movement in a light deprivation greenhouse will only help maximize the efficiency of the ventilation system. Air movement is also how growers mimic wind in an enclosed environment. In nature, wind strengthens the cell walls of a plant’s stem and directly influences a plant’s structural integrity.

“Choosing the right SHADE MATERIAL CAN SIGNIFICANTLY

help with cooling.”

Keeping Cooler Temperatures During Hot Summer Months

Protecting the dark cycle of a light deprivation greenhouse is extremely important and keeps the crop’s flowering cycle unhindered. By implementing convection, mechanical fans, oscillating fans, and evaporative coolers during the unshaded period of the day, a grower can vastly reduce heat build-up in the greenhouse. During the shaded or dark period, growers must rely on light traps in conjunction with mechanical cooling equipment, ensuring things stay cool and that the dark cycle will not be breeched. After all, if the ability to provide the crop with a true dark cycle is compromised, it defeats the purpose of light deprivation. Light deprivation greenhouses that use light traps to protect the dark cycle will not only produce prolific yields but will also more closely replicate the sought-after results of highly controlled indoor gardens.

s winter winds down, you may find yourself flipping through seed catalogs and daydreaming about this year’s garden. Soon it will be time to come out of hibernation and start the back-breaking, yet enjoyable work of digging in the soil. Until then, you can get a jump on your garden by starting your seeds indoors. Not only is it less expensive than buying starts, but you also have more options. Garden centers tend to carry a limited variety of starts, but you have the opportunity to experience flavors you would otherwise never taste when you germinate your own seeds. Starting your seeds indoors also gives your plants a head start by minimizing risks. They won’t have to contend with harsh winds and rains, slugs, or hungry rabbits. You can keep them safely protected in an ideal environment until they are old enough to be hardened off and planted outdoors. However, starting your own seeds indoors isn’t foolproof. Most people who have tackled this project have had seedlings die or not germinate at all. The process is simple, but it can be somewhat of an art and it pays to learn from others’ experiences.

Set Yourself Up for Success

“STARTING YOUR SEEDS INDOORS ALSO GIVES YOUR PLANTS A HEAD START BY MINIMIZING RISKS.”

Maximum Yield

First things first, it is important to get your timing right. A common mistake is to start your plants too early. Different plants require different time frames, so do a little research on each plant you plan on growing. For example, artichokes, celery, and onions should be started about 10 weeks before your last frost date. Broccoli, cauliflower, and tomatoes should be started about six weeks before, while pumpkins, cucumbers, and cantaloupes only need about three weeks. You also need to make sure your seedlings have the right environment to thrive. Most importantly, consider the amount of light they receive and their soil temperature. Most seeds need darkness to germinate, though there are exceptions. For example, lettuce, poppies, and snapdragons need light to sprout. Your seed packet should tell you what your individual seeds need. Once your seedlings break through the soil, ensure they have enough light. Often, a window is not sufficient. You will have better success if you use a grow light on a timer. Place the light about two inches above the seedlings so they don’t grow long and leggy, and give them 12-16 hours of light per day.

Most seeds germinate at 65-75˚F, but each plant has its own optimal soil temperature. For example, peppers germinate in eight days at 86˚F, but take almost two weeks at 58˚F. Eggplants, melons, pumpkins, squashes, and tomatoes all have optimum soil temperatures between 80-95˚F. You might be able to achieve these temperatures by placing your seedling trays on top of the refrigerator; however, a heat mat with a temperature controller is better if you want to be more precise. You can test soil temperature by inserting a soil thermometer three- to four-inches deep in the soil.

Choose Your Medium and Containers

Next, gather your containers, clean them, and fill them with the proper medium. Most garden centers carry seed starter trays with individual cells that you can fill with a seed starting mix. They usually have matching trays to catch water and clear plastic domes that help your soil retain moisture between watering. Be sure to clean your containers with a bleach solution to prevent fungal diseases. You can also use small paper cups, rolled up newspaper, or toilet paper rolls to create tiny pots if you would like to stay away from plastic. Whichever container you use should hold about three to four ounces of seed starter mix and have drainage holes. Instead of purchasing clear plastic domes, you can simply use plastic wrap to cover your seeds. Puncture the wrap with a few holes to allow for air flow. The medium you use is very important. Seedlings need more air flow than standard potting mixes provide. You can buy a soilless seed starting mix, or you can prepare your

own with equal parts peat moss and vermiculite or perlite. Presoak your medium, fill your trays and containers to the top, and then tamp down on the mix to get rid of air pockets.

Prepare Your Seeds

Depending on their natural habitat, seeds may require certain environmental factors before they germinate. For example, seeds native to deserts usually need a good soak from the rain before they pop. Seeds whose native climate has cold winters benefit from time spent in a dark, cool, moist place. You can learn what each plant needs by reading the seed packet and doing some minimal internet research. To improve your chances of success, you can prepare your seeds with stratification or scarification. These techniques can take days off the normal germination time. Stratification is when you trick seeds into thinking they are experiencing winter by putting them through a period of moist cold. You can do this by soaking them and putting them into a plastic bag filled halfway with moist seed starting mix, then placing the bag in the fridge.

“SEEDS CONTAIN ENOUGH NUTRIENTS TO FEED THEMSELVES UNTIL THEY SPROUT.”

When you see the roots peeking out, use a spoon to scoop out the seed with some medium and plant it in a small pot. Scarification is ideal for bigger seeds with a thicker skin. This is when you break the seed’s skin with either a pocket knife or a little sandpaper so that moisture can reach the embryo inside and start the germination process. All but the smallest seeds usually benefit from a 24-hour soaking. Be sure not to soak them for longer than this or they could rot. Once they swell up, plant them right away and keep them moist. If you have seeds that are a few years old, you can check their viability with a couple of different methods. The first is to place your seeds in water. It is likely that the ones that float won’t germinate. This method is not always accurate, however, so if you want to have a better idea if your seeds will sprout, place 10 seeds from the packet between two wet paper towels. Then, place them in a plastic bag on top of the fridge for a little added warmth. If only a couple of the seeds sprout, then there is a good chance you are wasting your time planting the entire packet.

Planting and Care

After you prep your seeds (or not), press the seeds gently into your presoaked seed starting mix. Plant two or three seeds per container (you can thin them later by snipping at the base with a pair of scissors so you don’t

disturb their roots). The general rule of thumb is to plant seeds three times as deep as their size. If they need light to germinate, however, press them lightly into the soil and barely cover them. Then, cover them with plastic wrap or a dome until they sprout, and then remove the covering. Be gentle when watering your seeds so you don’t disrupt them. Mist them with a spray bottle, use a turkey baster, or water them from the bottom. Seeds contain enough nutrients to feed themselves until they sprout. Once they break through the soil, however, feed them with a diluted fish emulsion or seaweed fertilizer. Some also recommend using compost tea to water your seedlings for accelerated growth. The sooner you can establish microbial colonies on their root systems, the more effective the microbes will be. Also, remember, at this point in their life, your sprouts need plenty of light. When your plants have two or three pairs of true leaves and are ready to go outside, you can foliar spray them with a neem oil treatment to prevent pests from attacking them right away (personally, I dilute the neem oil a little more than I usually would since they are so young). This may stress them slightly, but it may also save them from hungry bugs. Preventing pests is a lot easier than fighting a full-blown infestation.

Hardening Off Your Plants

Before planting your babies in the garden, you need to acclimate them to harsher outdoor conditions. You can harden them off by putting them outside for a few hours every day. For the first few days, put them in a shady spot that is shielded from wind for a few hours. Over the next week, gradually increase their time outside and the amount of sun and wind exposure they receive. Once they have toughened up, transplant them into the garden on a cloudy day or in the late afternoon so the full sun doesn’t shock them. Starting your seeds indoors can save you money, give you a head start on the growing season, and offer you more options than your local garden center provides. These tips will help you avoid failure and start your garden with happy plants.

FUSARIUM WILT:

Unwanted

& Unwelcome Feared because it is virtually impossible to get rid of, fusarium wilt is wreaking havoc on lettuce and other field and greenhouse crops. Lee Allen explains how the fungus is being studied, and if there is any hope of stopping it.

usarium wilt, a soilborne pathogen, is like that relative you just can’t stand — the one you aren’t happy to see when he shows up because you know once he arrives, he’s going to be around for a long time. That unwelcome arrival was first reported in Japan in the 1950s before it started to spread, arriving in California (primarily Fresno, Monterey, Santa Cruz, and southeastern Imperial County) in the early 1990s, then it hit the western Arizona lettuce fields, where it was first spotted in 2001 before it really began to branch out. “It’s marching around the world,” says Barry Pryor, a researcher at the University of Arizona (U of A). Fusarium wilt is dreaded by those who farm open fields as well as those who grow under glass. It will attack tomatoes and can render iceberg and romaine lettuce unmarketable. “It’s boxing growers into a corner, unable to meet market demand at certain times of the year,” says Paul Brierley of the Yuma Center of Excellence for Desert Agriculture (YCEDA), where fusarium wilt on lettuce management techniques is their top priority. “Other soilborne diseases are treatable. Fusarium wilt of lettuce is not,” Brierley warns. “Once you’ve got it, it’s there to stay because we don’t yet know a good way of getting rid of it.” The aggressive pathogen causes disease in lettuce but may be sustained on the roots of many plants, according to researchers from the University of California. It exists in three categories — Race 1, Race 2, and Race 3. Race 1 is found in lettuce and favors high soil temperatures. Once introduced into a field, the fungus will probably remain indefinitely. While lettuce and tomatoes are susceptible to Race 1, Race 2 and Race 3 will attack a variety of crops like peppers, soy beans, eggplant, and potatoes, which are especially vulnerable to Race 3.

Field Trials Ongoing

The U of A and YCEDA began a public-private partnership more than three years ago, collaborating with lettuce growers in Yuma — where 90 per cent of America’s winter leafy green vegetables come from — to figure out what to do with the disease that causes so much loss. Researchers say about $9 million in lettuce is lost annually in Yuma fields alone. Brierley’s researchers have been examining several different angles involving the pathogen by working with it in trials in heavily infected fields. “You need trials to be ongoing with current seed varieties and soil combinations as well as current biological and chemical products, which, to date, have been discouraging to be honest,” says Brierley. “We haven’t found anything to be effective yet.” Steaming infected garden beds and breeding resistance into seeds are two methods being discussed, as is genomic analysis. “We’re working with a start-up company on genomic sequencing and DNA analysis of the soil, so they can tell in a single analysis what different types of soilborne diseases might be present, as well as different pressures expected for the disease,” says Brierley. “That would offer advanced indication of what kind of pressure you’d have for Fusarium wilt as you decide where to plant your lettuce.”

“Fusarium wilt is dreaded by those who farm open fields as well as those who grow under glass. It will attack tomatoes and can render iceberg and romaine lettuce unmarketable.”

Dependent on Heat

Fusarium wilt is dependent on heat, a big problem in the Yuma area. “The problem is mainly in our fall crop planted in September when it’s still 100°F-plus in the field,” Brierley says. “When we plant winter lettuce in the November timeframe with cooler temperatures, we have virtually no problem at all.” But avoiding the hot months when planting isn’t an option. “We plant every day because lettuce is a perishable commodity that requires daily delivery. Waiting until temperatures drop a bit would be nice, but the product is driven by market demand and existing contracts,” added Brierley. Seed companies are also involved in the trial research, seeing if they can breed a variety that will fight Fusarium. In one field trial, Fusarium wilt had a 98 per cent kill rate, but there were two seed varieties from one company that mostly survived it. If those seeds can withstand further testing, they may become a commercially viable option. Type of soil is another area to study as some soils holding plants with Fusarium didn’t lead to actual plant damage. Researchers are experimenting with fumigation — killing everything in the soil to eliminate disease — and biome build-up, creating a stronger, healthier environment in the soil to naturally fight off disease.

Mike Matheron and Barry Pryor split Fusarium research duties — Matheron in the open field, Pryor doing greenhouse research. “I focus on variety of product rather than the soil it’s grown in. I’m looking for head lettuce cultivars that are resistant to the disease,” says Matheron. “There aren’t many that are… and that’s the problem.” Currently studying the disease and its relationship to different types of soils, Pryor is using polymerase chain reaction-based technology and loop-mediated isothermal amplification methods to determine how long it takes the lettuce to become infected after pathogen exposure. “The great thing about these methods is we can now have detection in the field in as little as 20 minutes,” he says. While wilt research continues with a hint of hope, Yuma lettuce farmers contend with today’s realities. Matt McGuire of JV Farms, which has more than 5,000 acres of iceberg and 3,000 acres of romaine, says farmers have become more production- and schedule-oriented in volume and timing of harvest. “We need the right volume on a consistent basis because our product isn’t storable like grains or dry goods,” he says. McGuire says cultural practices, seed treatments, chemical treatments, and field rotation have yet to show any positive effects. Only the seemingly resistant seeds and DNA soil testing that identifies infected fields are maintaining hope. “We should see more new items like this in the coming years, but those, presently, are the only things that give me optimism,” says McGuire.

TR ANSMITTANCE THROUGH GREENHOUSE GLAZING by Ian Ashdown

Maximum Yield

Lighting expert Ian Ashdown examines why there is less photosynthetically active radiation at the canopy level in a greenhouse compared to light measured outside.

ook at a greenhouse manufacturerâ&#x20AC;&#x2122;s product specifications and you will see that the light transmittance of singlepane clear glass is typically 88 to 91 per cent. Compared to double-wall polycarbonate with a transmittance of 80 per cent, it would seem glass is the better choice. However, if you measure the photosynthetically active radiation (PAR) at the leaf canopy within the greenhouse, it is often only 40 to 60 per cent of that measured outside the greenhouse. Why is this?

EFFECT OF INCIDENT LIGHT ON GLAZING MATERIAL

The answer is that these transmittance values were based on standard test procedures developed by the American Society of Testing Materials (ASTM), which require the incident light to be perpendicular to the glazing material. For greenhouses, however, the incident light comes from direct sunlight, diffuse daylight, and daylight reflected from the ground and other exterior surfaces. In other words, light is incident upon the glazing material from all angles. To better understand the issue, look at a sheet of clear glass. When it is perpendicular to your line of sight, it is essentially transparent. However, as you tilt the glass, you begin to notice reflections. These reflections increase in brightness until you are looking at the glass at a grazing angle, at which point it behaves essentially like a mirror. This also happens, of course, with daylight entering the greenhouse. On a clear day, this is mostly direct sunlight, and so the amount of sunlight entering the greenhouse depends on the incidence angle (Fig. 1). Assuming that the glazing material is perfectly transparent (that is, it does not absorb any light), the PAR light transmittance varies with the incidence angle (Fig. 2).

TR ANSMITTANCE OF DIRECT SUNLIGHT THROUGH CLEAR GLAZING

To put this into perspective, consider a gutterconnected greenhouse with a 1:2 (30 degree) roof pitch and double-pane glass glazing that is located in Vancouver, Canada, at a latitude of 49 degrees and oriented on an east-west axis. The solar elevation at noon on December 21st will be 18 degrees. The incidence angle will be 42 degrees, and so the transmittance of the south-facing roof panels will be 48 per cent. We can now see where the “40 to 60 per cent” figure comes from. It is important to note that these results apply only to clear glazing materials with smooth surfaces, such as glass and acrylic. For materials such as polyethylene and polycarbonate with rough or striated surfaces that tend to diffuse the incident light, it becomes more difficult to predict their optical characteristics. A better approach is to measure their transmittance for various incidence angles in a test laboratory. Predicting the precise amount of daylight that will be incident upon the leaf canopy in a greenhouse can be done, but it requires a horticultural lighting design program that considers building latitude and orientation, building layout and dimensions, glazing materials, date and time, weather conditions, and more. For now, however, it is sufficient to see why the measured light at the leaf canopy is considerably less than what is measured outside.

fter a seed has sprouted â&#x20AC;&#x201D; but before it enters the preadolescence of vigorous vegetative growth â&#x20AC;&#x201D; plants go through an oft-overlooked and frequently under-appreciated seedling (pre-veg) stage. While the time spent in this stage is usually limited to a week or two, it can be fraught with opportunities for mistakes by unseasoned growers and is less forgiving of errors than mature plants.

Anatomy of a Seedling

Inside a seed is a miniature, undeveloped plant, packaged in a protective shell. A seed can survive without light or additional moisture for months (sometimes years) in a state of suspended animation under conditions that would kill the same plant in any other life stage. Seeds should be kept in a cool, dark environment away from moisture or high humidity for long storage periods. Before sprouting, some seeds require a moist period of lowered temperatures to simulate winter in a process called stratification. Seeds sprout when environmental conditions are favorable and moisture enters through small holes in the seed coat called micropyles. The moisture causes the dehydrated plant to swell, and hydraulic pressure bursts the seed coat from the inside. Food stored in the endosperm feeds the sprout until it has developed the ability to photosynthesize. The sprout sends down a root (radicle) to draw in moisture and nutrients, then sends up and unfurls a single seed leaf (cotyledon) in the case of monocots (monocotyledonous plants), or a pair of seed leaves in the case of dicots (dicotyledonous plants).

Plants with only these first seed leaves are commonly called “sprouts.” Meristem cells are among the most important to new development as they are undifferentiated and can further develop into a variety of specialized cells depending on location and need. The apical meristem at the tip of the radius develops into the root system, while the apical meristem between the seed leaves develops into the first growth tip. Once the first true leaves start to appear, the plant is considered a seedling. Once sprouted, the plant goes from one extreme to the other; from its most durable stage to its most vulnerable.

Starting Seedlings

Seedlings can wither and die in a matter of hours without proper moisture. They don’t have an extensive enough root system to reach very far within the growing medium to take advantage of large containers, and as such are frequently started in smaller containers, then transplanted as they increase in size. Nursery pots sized to fit 1020 trays are a common choice, as are plastic beverage cups. Seedlings planted directly outdoors should be well marked and protected from flooding or other traumata. Markers or garden maps can be helpful in ensuring each mature plant can be identified if multiple varieties of the same type of plant are grown. While it can be obvious to visually tell the difference between a squash sprout and a tomato sprout, telling the difference between similar tomato varieties can be difficult before fruit set, so keeping a record is handy.

Dos and Don’ts for Pre-Veg Seedlings

• Overwatering can be as detrimental as giving too little water. Aside from the potential to drown the plants if kept in stagnant water, an abundance of moisture or humidity can lead to a fatal fungal infection known as “damping off,” which is generally considered untreatable once infected. • Seedlings require light to grow, but high-intensity discharge lighting can be detrimental. Of particular risk is heat damage, which can not only overheat the plant directly, but can cause indirect damage by drying out the grow medium. • Their small size means they are more susceptible to physical attacks and mishaps than established plants. Even a single insect bite that would go practically unnoticed on a larger plant can put an end to a tender seedling. • Errors in nutrient solutions are magnified when dealing with seedlings. Nutrient solutions for seedlings should be kept mild and simple. They are not tolerant of overfeeding and are particularly susceptible to nutrient burn and negative reactions from intense additives. • Particularly in the case of moving indoorgrown seedlings to the outdoors, hardening off can help reduce the stress from a change of environments. One approach to hardening plants is taking them outside during the mildest part of the day for an hour for the first day, and for an additional hour each consecutive day (two hours on the second day, three hours the third day, etc.) for a week to 10 days. By giving

the plants time to acclimatize from their (hopefully) idyllic indoor conditions to the harsher realities of outdoor life, the shock of the experience can be mitigated and the stress reduced. Hardening off is generally not required when moving to a milder environment, so outdoor plants can be moved indoors (after a quarantine period) with relative safety. • Similar to hardening off, if the seedling will be grown under harsher high-intensity discharge indoor lighting, it is less stressful to gradually increase the intensity over a period of time than making a harsh transition to the new environmental conditions. This can be accomplished by first moving to the periphery of the lit area for a few days before placing directly under the lighting fixtures. It behooves a gardener to take particularly good care of their seedlings, as they are the tender starts to robust mature plants. Healthy seedlings enjoy a more vigorous growth spurt from transitioning into adulthood, whereas sickly starts can take additional time to recover from their retarded development before maturing.

Leaks

in hydroponic equipment

When you work with water, pumps, and pressure, youâ&#x20AC;&#x2122;re eventually going to have leaks. The risk of springing a leak in your hydro system can be mitigated, however, by identifying the most susceptible areas and sticking to an inspection schedule.

Maximum Yield

over time due to the pressure of the water and, possibly, the roots. Wear and tear can happen, and over time even the most durable materials can be weakened under the strain caused by the water and weight. You’ll want to keep an eye on your reservoirs for any potential issues. When you find a weakened area, assess it to see if there’s a way that you can shore it up or repair it.

Hose Fittings

The hose fittings on your spray or drip system need to stay tightly in place. However, the pressure of the pump can cause them to weaken or move over time. They can even eventually become disconnected. This type of leak can be a big mess to handle. You may find it necessary to set a regular maintenance schedule to keep them staying secure and in good condition or replacing the fittings when needed.

“Leaks are possible in any set-up because you’re working with water.” by Shannon McKee

ne of the biggest issues that you can have with your indoor hydroponic set-up has to do with water: leaks. Leaks can be a pain. When they occur, leaks create slipping hazards, waste water and nutrients, and take effort to clean up. While high-pressure systems are more likely to leak than low-pressure systems because of the pump pressure used, leaks are possible in any set-up because you’re working with water. Here are some common areas you can experience leaks and how to keep them from returning in the future.

Reservoirs

Reservoirs may experience leaking when you use a deep water culture set-up or similar system. This issue can happen if you have many roots and a smaller reservoir. It’s important to have a reservoir big enough to handle what you’re growing in addition to the amount of solution that needs to be run through the system. You also must keep in mind the roots themselves can become clogs that cause leaks and other issues. Also, depending on what your grow set-up is made of, you may have areas that get weakened

Part Size

The size of your pipes may also cause some issues with leaking in your hydroponic system. Going too small with your pipes to save money may result in your system having leaks, which can evaporate any savings gained from the smaller pipes. Pipe size can also be an issue if you have vigorous roots that are able to get into them.

Power Issues

Power issues are another factor that you need to watch when it comes to leaks. If your hydroponic system loses power, this can cause your solution to drain back into your nutrient reservoir. Not having the power necessary to push the water and nutrients to your plants can be a leaking hazard if your reservoir isn’t big enough to accommodate all the solution coming back at it. You’ll experience an overflow of all that excess liquid. The key is to always to be vigilant. Check out the different areas where leaks can happen, including all junctions, fittings, and connections. Also look for places where cracking may occur or for parts that may slip from where they should be. There are some things that you may not have control over, such as power outages, but looking over your system often can help you to prevent many of the leaks that could turn into real issues for your hydroponic growing set-up. Keep your expensive water and nutrient solution in your system by identifying potential problem areas and by creating a maintenance inspection schedule and sticking to it.

2601 S. Lemay Ave. Ste. 7 #402, Ft. Collins, CO, 80525 1 year in business • 1.720.772.9767 • impellobio.com

Impello Biosciences is a leading provider of advanced biostimulant technologies for crop cultivation. Their integrated solutions — ranging from growth-promoting microorganisms to other bioactive compounds — support the agriculture industry around the world to increase the quality and output of crop cultivation in a sustainable manner. Impello CEO Michael Key, COO Eric Hagstrom, and CCO Adam DeRosa took time to answer our questions.

What did you and your partners do before starting Impello Biosciences?

Michael Key gained an in-depth knowledge of both technology and agriculture as the Director of R&D at Functional Remedies, the first certified-organic hemp farm in the world, and in the Center for Rhizosphere Biology at Colorado State University. Eric Hagstrom worked for CW Technologies, a small business investment firm in Madison, WI. There, Eric operated behind the scenes at CW Tech to identify potential high-value startups. Adam DeRosa worked as a business consultant for The Regis Company in Golden, CO. From there he brought an exceptional understanding of business development needed to take action.

How did you get into this industry?

Initially, Michael held the position as the director of research and development at Functional Remedies, a hemp farm in Pueblo, CO. It was on this farm where Michael began utilizing his knowledge in rhizosphere biology to develop and apply new biostimulants in the field. After developing microbial inoculants for Functional Remedies, he saw an opportunity to add value to the entire cannabis industry with the development of new biostimulants. Shortly thereafter, he formed Impello Biosciences with Eric and Adam. From the beginning, we knew we wanted to use our past experiences to design products for high-value and fastgrowing crops like the cannabis industry.

When and where did Impello begin?

Impello was founded in Fort Collins, CO, in May 2017.

What were the start-up years like?

The start-up years take over your life, and we still consider ourselves in that phase. We learned quickly that being in a start-up requires a lot of hard work, patience, sacrifice, and emotional balance, but it also offers endless opportunity. 58

“

IT’S OUR GOAL to create products that help growers improve efficiency and achieve a higher quality.”

Because we are a young organization, we are able to devote a lot of our time working directly with growers to implement our biostimulants. We get to see firsthand what the grower really needs, what works for them, and what doesn’t. It has taught us to never stray too far away from the grower, and to keep our eyes and ears on the frontlines where our products are used.

How does Impello’s philosophy translate to opportunities?

We are driven by innovation. It’s our goal to create products that help growers improve efficiency and achieve a higher quality — something other products haven’t been able to do before. By incorporating these technologies, growers are able to make significant improvements in their operation without changing their current infrastructure.

What did you first produce?

The first product we developed at Impello was Tribus Original — it’s our first microbial inoculant and a reflection of the latest advances in rhizosphere biology. Tribus is a consortia of three species of bacteria that, when combined, are capable of promoting plant growth through pretty much every known microbial growth-promoting mechanism. These three bacteria help both each other and the plant grow, so it’s a powerful symbiotic relationship on all levels that produces visible results.

What were some of your struggles as you started the business? How did you overcome them?

Establishing our message was a difficult task we faced early on because biostimulants represent a newer understanding of agricultural inputs. So, in order to facilitate understanding, we dialed in our message and made it easier to digest. We refocused our efforts on educating our customers about biostimulants and the role they play as a tool for crop improvement and sustainability. We’re learning more and more about biological tools each day, so it’s important for us to keep people in the know.

How did you gain market share and recognition?

Our background in large-scale cannabis farming — where we had a chance to develop and implement our products with industry leading farms — created deep ties in the industry from the get-go. Word of mouth from our partners early on became one of the best tools for gaining market share and recognition. We have developed very strong relationships with our partners and clients, and often times they will showcase their grow operations and results from implementing our biostimulants to others who want to see what they are capable of achieving. We like to let the results of our products do the talking.

Where do you distribute?

“

Our distribution channels include North America, South America, and Europe right now, and we are looking to introduce our products to new markets!

CONSTANT EVOLUTION gives us

endless opportunities to be innovative and explore new technologies.” We also have had many opportunities to speak on panels and at trade shows to help spread awareness and understanding of biostimulants. Impello has a presence across many social platforms where we are able to connect with a new generation of growers around the world.

Has Impello moved or expanded since the beginning? Our headquarters is in Loveland, CO.

What is your current product line?

Currently, we offer a unique line of biostimulants. Our microbial inoculants include Tribus Original, a seedling-harvest inoculant, Tribus Grow, an inoculant designed for vegetative growth, and Tribus Bloom, our microbial formula for the flowering phase. We also offer liquid organic nutrients called Innate Grow and Innate Bloom, which contain amino acids and organic acids that stimulate both plant and microbial growth. We also just finalized our third product group that we are releasing soon.

How many people work for the company? Currently, Impello has seven individuals in the US and one in Europe.

What are your company’s strengths?

Technology and innovation are dynamic — meaning they are constantly changing and improving. Being a technology-driven company, we see this as an advantage rather than a burden. Constant evolution gives us endless opportunities to be innovative and explore new technologies.

What are some of your proudest moments?

It’s been incredibly rewarding to see farms implement our products and realize that our technologies really deliver — they actually are the future of agriculture.

What significant things have you learned so far about the industry? As competition grows, farmers are looking for the newest and best technologies to help them remain competitive in the marketplace. These technologies, however, must always be practical and easy to use.

What have you learned about starting and growing a company? Great ideas and great products don’t sell themselves.

wherever you are, whatever youâ&#x20AC;&#x2122;re doing,

weâ&#x20AC;&#x2122;ll come

to you. What words of wisdom can you share about the business, the industry, or the future of the industry?

Developing biostimulants has been remarkably rewarding. Biostimulants are part of a revolution; a new wave in agriculture that is increasing global food outputs and diminishing unsustainable practices that have been so detrimental to our environments and societies. And further, working with growers in the cannabis industry, we have seen firsthand the importance this crop has played in so many peopleâ&#x20AC;&#x2122;s lives. The future of the cannabis industry, the future of all agriculture, and the future of biostimulants is bright.

What makes your employees so awesome? How does your team bond? The three of us founders grew up together in Madison, Wisconsin. We all went to different universities but ended up back together starting Impello several years later. We have a level of trust and respect that is crucial to success.

ten FACTS ON

CHLOROPLASTS by Philip McIntosh

No organelle is as closely identified with what it means to be a plant than the chloroplast.

FROM GREEK, CHLOROS means green and plastos means formed. Indeed, chloroplasts are well-formed small green entities that in some ways look and act like miniature cells within the cell. IT IS PROBABLY one of the most universally known biological facts that plants are green because they contain chlorophyl, and chlorophyll is critical for photosynthesis.

OF COURSE, CHLOROPLASTS contain chlorophyll,

but there is so much more to them than that. Estimates put the number of proteins to be found at work in a chloroplast to be between 3,000 to 5,000.

WHERE DO ALL those proteins come from?

Some come from the relatively small genome (120,000 to 150,000 base pairs) of the chloroplast itself, which means the rest are coded for by the nuclear genome and must be transported into the chloroplast.

AS IS TRUE for mitochondria, chloroplasts possess their own DNA which is much like that of bacteria. THAT AND OTHER evidence suggests that, as is also the case for mitochondria, chloroplasts originated as prokaryotic cells that were engulfed by early eukaryotes, eventually co-evolving into a symbiotic relationship. CHLOROPLASTS, UNLIKE MOST other organelles, possess two membranes instead of the usual one. As you might guess, there is one other organelle enclosed by a double membrane (hint: it starts with an m). INSIDE THE CHLOROPLAST double membrane is an aqueous liquid called the stroma. The stroma is where the Calvin cycle takes place. THE CALVIN CYCLE is a series of light-independent reactions that produce carbon compounds using carbon dioxide as a carbon source.

THE LIGHT-DEPENDENT REACTIONS take place in stacks

of flattened membranes called grana, where electromagnetic energy is absorbed by chlorophyll and converted into chemical energy which is then used to drive the Calvin cycle.
