Going Vertical: How Vertical Farming Is Revolutionizing the Cannabis Industry

By Jeffrey L Garber

In the cannabis industry, it’s crucial to be able to predict the future, to adapt and survive in a competitive industry that is arguably regulated more closely than any other.

From licensing to buildout, there are a growing number of barriers to entering the cannabis industry as a cultivator. Those who are lucky to successfully establish a grow operation are well aware that one of the crucial hurdles is managing space to maximize facility efficiency and capacity.

To stay profitable, the more plants you can grow and harvest at a time in a continuous cycle, the better. From an economic and environmental perspective, managing cost, space and time comes down to automation and efficiencies. One of the most efficient ways we optimize is through the practice of vertical farming.

Vertical farming maximizes canopy square footage while minimizing Cost of Goods Sold (COGs) to produce high-quality cannabis at scale year-round, and the industry is slowly finding that this method is an incredibly efficient and profitable way to maximize cannabis output.

Yellow Dream Farm is our family-owned cannabis cultivation, manufacturing and distribution company based in San Bernardino County, California, often known as the Silicon Valley of cannabis. Our craft, boutique-style cannabis is grown from floor to ceiling in the 30,000-square-foot facility. We’re using cutting-edge technology that’s only come to market in the last five years and using a variety of sustainable practices. With environmental and feeding efficiencies, we’re able to harvest 300 pounds per week when compared to 150 pounds per week from a facility of the same size.

Vertical Farming for Space Optimization

Like any medical field, cannabis has seen large numbers of outside investments into the space, bringing ideologies and efficiencies from other time-tested industries. One such efficiency is vertical farming – a practice already seen in large-scale agriculture.

We choose vertical farming to maximize our canopy square footage and minimize COGs to produce high-quality cannabis at scale. The barrier to entry into the cannabis industry is expensive, and you must utilize every square inch to stay profitable. We believe vertical farming is the most efficient and most profitable way to maximize output and our numbers can back that up; for example, we can produce double the amount of flower than the average single-tier room with the same square footage, without doubling the cost.

Our rooms contain double stacks to double room capacity by using ceiling heights instead of square footage. Even though vertical farming has larger start-up costs, we can maximize square footage and output, allowing us to get a better and faster ROI. Vertical farming can be done in many different ways but the way we built our facility was always with a sustainable outlook. We also look to improve and remove human error; with full irrigation control and crop steering technologies, we can recalibrate sensors, irrigation media and environmental sensors when needed based on successes, challenges or environmental constraints. Additionally, we have a few other sustainable practices that make a difference.

Water Conservation, Lighting and Automation

Being a California-based grower, water conservation is a key part of our operations. With San Bernardino County being located in the heart of the high desert, conserving water is not only a requirement but a competitive advantage. Our practices provide cost savings which we then pass along to our customers. Each cannabis plant on average requires between a half gallon and one gallon of water per day, which we then recirculate through condensate water from our A/C and dehumidifiers. All runoff nutrient water is re-filtered and reused to get the most out of our nutrients before discarding waste. Our freezer panel walls hold temperatures at consistent rates, and we have a fully automated system to dial in specific needs at any given time.

Lighting is another major environmental and capital cost. Our primary lighting system is LED technology, and we use LED spectrums to find which spectrum benefits the plant most. With LEDs, our energy consumption is 30 percent less.

Vertical Farming Is the Future of Cannabis and Agriculture

Vertical farming has been hailed as the future of many agricultural industries and cannabis is no different. We already see large vertical farms in most legal states, but surprisingly it’s still not a common style of growing. As the price per pound steadily declines in California, being able to keep COGs down will allow vertical farmers to sustain and thrive in this volatile industry.

In order to adapt, grow and leave a positive mark on the industry, we must pave the way for new styles of growing and utilizing new technology and science that was not available to growers in the past. We can use these advanced new technologies to make real-time changes to each sector of our facility and optimize both people power, and energy efficiency. And most importantly, we’ll be able to produce top-quality cannabis for adults to enjoy at affordable prices.

Clean Green Farming is Good for Cannabis

By Khalid Al-Naser

At Raw Garden, we have a ‘Farming First’ philosophy because we understand that the process of farming is the process of managing the plant’s life and the management of the land those plants grow on – this is when the plantgets its chance to thrive but requires that it is properly nurtured in order to provide resources such as high-quality terpenes and cannabinoids.

Our cannabis plants are sun-grown in Santa Barbara county soil just like other California crops. From the seed to the shelf, we are vertically integrated and maintain quality control at every step in the process. We grow our own seeds, farm and harvest our own plants, and process our own products while employing sustainable and regenerative farming practices – only organic and natural fertilizers, soil amendments and pest control methods are used on thefarm.

As farmers we have a responsibility to care for the land and the soil to ensure it is fertile and healthy well into the future. We take care of the soil and it takes care of our plants. The result is premium quality products that our customers love and trust. Our success and commitment to quality is proof that the economics of clean, sustainable operations are achievable. We’re farmers and scientists on a mission to make clean, high quality cannabis that is affordable and accessible.

A few of the sustainable agriculture practices we employ at Raw Garden include:

Clean Green Certification – Since our inception, we have been certified and licensed members of Clean Green, the #1 globally-recognized organic and sustainable cannabis certification program. The program was created in 2004 as a way to standardize legal cannabis products and the result was a program to help farms and brands obtain organic-like certification based on the USDA National Organic program. Clean Green-certified growers and processors regularly win awards for their high-quality products, including our award-winning extracts.

Water Conservation – Our farm team waters at the right time of day to reduce evaporative water loss; we also use drip irrigation and mulch to reduce water waste and runoff. Last year, we used about 8,000 gallons of water per acre on average, which is significantly less than standard outdoor grown crops.

Natural Fertilizer and Pest Control – We apply only organic fertilizers and foliar feeds and we spray only organic pathogen-free inoculants to keep our plants healthy and disease-free, which consistently results in high yields. To naturally deter pests, we recruit beneficial predatory insects like ladybugs and parasitic wasps, in addition to botanical oils and diatomaceous earth.

Precision Agriculture (PA) and Site-Specific Crop Management (SSCM) – We utilize technology to manage crops and increase farm efficiency, such as machine learning for fertilizer optimization and digital sensors in the field to monitor crops.

Soil Health and Terroir – Like grapes for wine, cannabis plants grown in the soil have terroir that affects the flower’s qualities, characteristics, terpene profile, aroma and taste, based on temperature, climate, soil composition and topography, as well as other environmental influences. Micro-climates matter – the same strain of cannabis grown along the coast likely has a different taste and potency than one grown inland. We grow in Santa Barbara wine country for the combination of fertile soil, hot sun, and cool nights which yield an incredibly diverse, potent and flavorful crop of cannabis flowers. Between growing seasons, we employ regenerative agriculture by planting cover crops including oat, beans, peas and buckwheat to add nitrogen and organic matter naturally back in the soil. This method of cover crops also helps reduce pests and soil-borne diseases in preparation for the next growing season. We know that an ideal environment in combination with healthy soil and good land management results in healthier, more vigorous plants, which translates to higher-quality products.

As farmers, it is our responsibility to care of the land with good management decisions today so that we grow the best quality products while better preserving the land for the future. It takes careful planning, knowledge of the land, a commitment to sustainable practices and a desire to put farming first.

Environmental Sustainability in Cultivation: Part 3

By Carl Silverberg

No Comments

Part 1 in this series went into a discussion of resource management for cannabis growers. Part 2 presented the idea of land use and conservation. In Part 3 below, we dive into pesticide use and integrated pest management for growers, through an environmental lens.

Rachel Carson’s book Silent Spring in 1962, is often credited with helping launch the environmental movement. Ten years later, VP Edmund Muskie elevated the environment to a major issue in his 1972 Presidential campaign against Richard Nixon. 57 years after Ms. Carson’s book, we’re still having the same problems. Over 13,000 lawsuits have been filed against Monsanto and last month a jury in Alameda County ruled that a couple came down with non-Hodgkin’s lymphoma because of their use of Roundup. The jury awarded them one billion dollars each in punitive damages. Is there a safer alternative?

“Effectively replacing the need for pesticides, we use Integrated Pest Management (IPM) which is a proactive program designed to control the population of undesirable pests with the use of natural predators, a system commonly known as “good bugs (such as ladybugs) fighting bad bugs”, states the website of Mucci Farms, a greenhouse grower. While this applies to cannabis as well, there is one major problem with the crop that isn’t faced by other crops.

While states are moving rapidly to legalize it, the EPA is currently not regulating cannabis. That is in the hands of each state. According to a story in the Denver Post in 2016, “Although pesticides are widely used on crops, their use on cannabis remains problematic and controversial as no safety standards exist.” Keep in mind that it takes a lot more pesticides to keep unwarranted guests off your cannabis plant when it’s outdoors than when it’s in a controlled environment.

We’re accustomed to using endless products under the assumption that a range of governmental acronyms such as NIH, FDA, OSHA, EPA, USDA are protecting us. We don’t even think about looking for their labels because we naturally assume that a product we’re about to ingest has been thoroughly tested, approved and vetted by one of those agencies. But what if it’s not?

Again, cannabis regulation is at the state level and here’s why that’s critical. The budget of the EPA is $6.14 billion while Colorado’s EPA-equivalent agency has a budget of $616 million. According to the federal budget summary, “A major component of our FY 2019 budget request is funding for drinking water and clean water infrastructure as well as for Brownfields and Superfund projects.” In short, federal dollars aren’t going towards pesticide testing and they’re certainly got going towards a product that’s illegal at the federal level. That should make you wonder how effective oversight is at the state level.

What impact does this have on our health and what impact do pesticides have on the environment? A former Dean of Science and Medical School at a major university told me, “Many pesticides are neurotoxins that affect your nervous system and liver. These are drugs. The good news is that they kill insects faster than they kill people.” Quite a sobering thought.

“We have the ability to control what kinds of pesticides we put in our water and how much pesticides we put in our water.”Assuming that he’d be totally supportive of greenhouses, I pushed to see if he agreed. “There’s always a downside with nature. An enclosure helps you monitor access. If you’re growing only one variety, your greenhouse is actually more susceptible to pests because it’s only one variety.” The problem for most growers is that absent some kind of a computer vision system in your greenhouse, usually by the time you realize that you have a problem it’s already taken a toll on your crop.

Following up on the concept of monitoring, I reached out to Dr. Jacques White, the executive director of Long Live the Kings, an organization dedicated to restoring wild salmon in the Pacific Northwest. Obviously, you can’t monitor access to a river, but you certainly can see the effects of fertilizer runoff, chemicals and pesticides into the areas where fish live and eventually, return to spawn.

“Because salmon travel such extraordinary long distances through rivers, streams, estuaries and into oceans they are one of the best health indicators for people. If salmon aren’t doing well, then we should think about whether people should be drinking or using that same water. The salmon population in the area around Puget Sound is not doing well.”

We talked a bit more about pesticides in general and Dr. White summed up the essence of the entire indoor-outdoor farming and pesticides debate succinctly.

“We have the ability to control what kinds of pesticides we put in our water and how much pesticides we put in our water.”

If you extrapolate that thought, the same applies to agriculture. Greenhouse farming, while subject to some problems not endemic to outdoor farming, quite simply puts a lot fewer chemicals in the air we breathe, the water we drink and the food we eat.

How Cannabis Can Positively Impact California’s Drought

By Lukian Kobzeff

2 Comments

As the drought in California persists and quickly becomes the new hydrological norm, many within the state have embraced efforts to find ways and means to live within the drought forced water “budget.” Because of the importance of water conservation, the cannabis industry should embrace its socio-ecological responsibility and seize the opportunity to help shift the perception of cannabis cultivation into that of a sustainable, high-value agricultural crop that can be grown in an environmentally safe manner, while using water efficiently.

The intersection of Prop 64, MCRSA and the drought provides the cannabis industry with a unique opportunity to positively impact water conservation. Because legal cannabis cultivators are just now designing blueprints for grow sites, these cultivators are in a position to build infrastructure and systems specifically designed to achieve permanent, sustainable water conservation.

By embracing and championing water conservation, the cannabis industry will achieve two goals: being a collaborative player in the larger community working towards sustainable water use and enhancing the overall perception of the cannabis industry in the conscious of the general public. For an industry seeking legitimacy, there is no better way to put cannabis in the mainstream conscious than by embracing environmentally responsible philosophies. Here are a few measures the cannabis industry should embrace:

Measure

The current drought has generated a state-wide conversation about tracking and recording water usage. Some commentators believe California is suffering from a water data problem. Recently passed AB 1755 is a step by California to address that shortcoming by creating a technology platform to aggregate and share water data. Cannabis cultivators should get onboard with measuring water usage. One method is to install sensitive flow meters in each drip station to precisely measure water used during each grow cycle. First, this provides the cultivator with a precise data set. Precise data sets are extremely important, especially when trying to achieve the two-part-goal of conserving water and maximizing crop yield. Second, having precise data sets allows the cultivator to determine, from harvest-to-harvest, increasingly precise ratios of input (water) to output (flower). Most likely, this input:yield ratio is subject to diminishing returns at the margin; that is, adding additional water will not proportionately increase crop yield. For instance, 50 units of water could produce 50 units of crop, but 75 units of water might only produce 55 units of crop. By measuring the input (water), the cultivator is able to identify the precise threshold where diminishing returns set in and can therefore reduce the “diminishing returns” water usage, saving money and conserving water.

Collaborate

Building on water-usage data collection, cultivators can then collaborate with each other and with water agencies. By sharing data sets, cultivators can quickly develop ideal input:yield ratios, can better understand how water usage fluctuates within each discreet grow cycle and can develop methods such as deficit irrigation and real-time soil moisture measurements. This collective industry knowledge will help each individual cultivator to reduce water-usage. In collaborating with local water boards, the boards will better understand how much water is being used and conserved by the industry. Additionally, if the boards have a more precise understanding of the expected usage per season or per specific period in a grow cycle required by cultivators in their jurisdictions, those boards can better plan for the peaks and troughs in water demand. Besides data sharing, agencies and cultivators can collaborate in developing “fill stations” (offering free, non-potable recycled water for irrigation), or help fund development of direct potable water technologies and other recycled water technologies. Collaboration amongst growers and with water boards will lead to greater water conservation.

Energy Saving

An ancillary benefit to water conservation behaviors is the reduction of energy consumption. It takes an immense amount of energy to pump and transport water to end-users, such as cultivators. Reducing water usage in turn reduces energy consumption, because less water used means less water transported and disposed of. This is one method for indoor cultivators to offset energy consumption. In addition to reducing energy usage by conserving water, cultivators can follow Irvine Ranch Water District’s example of implementing an energy storage system to reduce costs and ease energy demand during peak hours. Indoor cultivators should adopt the same basic structure and mechanics: install Tesla battery packs to store energy for use during peak hours (when electricity is more expensive) and recharge the batteries at night when demand is low (and electricity is cheaper).

Opportunities Abound

This is an exciting time in California’s history, with the pending election of Prop 64, the passage of MCRSA, and the opportunities present in the water-energy nexus. The $6 billion cannabis industry has an incredible opportunity to have a far-reaching impact on water-conservation. By being an active collaborator conserving water, the cannabis industry can position itself as a trendsetter and private sector leader in sustainable and eco-conscious methods, technologies, and processes.
