Controlled Environment Agriculture: An Interview with Sam Andras

By Aaron Green
1 Comment

Food-focused controlled environment agriculture (CEA) is a multidisciplinary production technique whereby plants and products are grown inside greenhouses, vertical farms and growth chambers where every aspect of the environment can be monitored and controlled. Using CEA, cultivators can produce high-value and traditional food crops with the goal of maximizing plant productivity in an efficient and environmentally friendly way.

As the industry’s first integrated building and cultivation systems design firm, urban-gro is ushering in a new era in the design of efficient indoor agriculture facilities, providing productivity and efficiency benefits to CEA operators when designing and operating facilities.

We interviewed Sam Andras, executive vice president of Professional Services at urban-gro, and principal of MJ12 Design Studio. Sam joined urban-gro after his company MJ12 Design Studio was acquired in July 2020. Prior to that, he was principal in charge of 2WR+ Partners, a 20-year Georgia-based architecture and interior design firm.

Aaron Green: Sam, tell me, how did you get started in the cannabis industry?

Sam Andras: I started my architecture firm in 2001 in Georgia and later moved to Colorado in 2012. In 2013, I had the opportunity to do three cannabis facilities and really saw it as an emerging market that I thought would be really cool to dig into and pursue. Due to the marijuana stigma at the time, our company, 2WR, decided to create a cannabis-specific entity and developed MJ12 Design Studio. We built a website and it took off. Since 2013, I’ve personally designed about 130 cultivation facilities and vertically integrated facilities, from Hawaii all the way to New Zealand.

Green: When you say vertically integrated, what does that include?

Andras: The full building design of cultivation, product manufacturing, extraction, infusion and dispensaries.

Green: Is that something urban-gro currently does as well?

Andras: Now? Yes, with MJ12 under the facility design umbrella. After urban-gro acquired us in July, they were able to start offering full turnkey services. Everything from architecture, mechanical and plumbing engineering, electrical engineering, integrated cultivation, design of fertigation, benching, lighting, water treatment, environmental controls and other plant focused services– all of that is under our umbrella.

Green: Can you explain what controlled environment agriculture (CEA) is?

Andras: Absolutely. To me, CEA is crop agnostic, it can be anything from leafy greens to cannabis. Though we’re mainly focused on the cannabis industry and controlling that environment, we do also serve some leafy green companies. Environmental control includes things like temperature and humidity levels in the various stages of growth which is key to the economic success of organizations.

I’m a firm believer in legalization on the federal level down the road, which means that everything’s going to be under FDA for human consumption. If you look at the European models, when you look at the medicinal product development, it’s focused on consistency of the crop, from one crop to the next. And the way you achieve consistency is with CEA.

Green: From a resource perspective, can you describe how CEA differs from indoor to outdoor and greenhouse?

Andras: When you look at the market and the sale value of cannabis flower grown indoors versus outdoors or even greenhouse, greenhouse growing has huge variations by region. I believe greenhouses function better in more of a dry, arid climate. Indoor grows give you the ability to design and control your entire environment including temperatures, humidity levels, plant sizes, watering rates and other considerations. Growing indoors, in a controlled environment, gives you more flexibility to explore different alternatives in your cultivation.

Green: Final question: what in cannabis or in your personal life are you most interested in learning about?

Andras: That’s a great question. I’m a hands-on kind of guy. I would love to spend a couple of weeks working in extraction, as that’s the piece of the puzzle, as an architect, I know the least about. We’ve designed pretty much every type of cultivation from drip irrigation aeroponics to aquaponics, ebb & flow. You name it, we’ve done it, but the whole extraction process and the different equipment, and why companies choose ethanol, butane, hydrocarbon, CO2 and how to design for those extraction processes is something that as an architect, I’d love to learn more about.

Green: Okay, Great. That concludes the interview. Thanks Sam!

Andras: Thanks, Aaron.

Back in November of 2017, urban-gro announced the development of their Soleil Technologies platform, the first technology line for cannabis growers utilizing Internet-of-Things (IoT). Today, urban-gro is announcing that line is now officially available.

The technology portfolio, aimed at larger, commercial-scale growers, is essentially a network of monitors, sensors and controls that give cultivators real-time data on things like temperature, humidity, light, barometric pressure and other key factors. The idea of using IoT and hypersensitive monitoring is not new to horticulture, food or agriculture, but this is certainly a very new development for the cannabis growing space.

According to Brad Nattrass, chief executive officer and co-founder of urban-gro, it’s technology like this that’ll help growers control microclimates, helping them make the minor adjustments needed to ultimately improve yield and quality. “As ROI and optimized yields become increasingly important for commercial cultivators, the need for technologies that deliver rich granular data and real-time insights becomes critical,” says Nattrass. “With the ability to comprehensively sense, monitor, and control the microclimates throughout your facility in real-time, cultivators will be able to make proactive decisions to maximize yields.”

One of the more exciting aspects of this platform is the integration of sensors, and controls with automation. With the system monitoring and controlling fertigation, lighting and climate, it can detect when conditions are not ideal, which gives a cultivator valuable insights for directing pest management or HVAC decisions, according to Dan Droller, vice president of corporate development with urban-gro. “As we add more data, for example, adding alerts for when temperatures falls or humidity spikes can tell a grower to be on the lookout for powdery mildew,” says Droller. “We saw a corner of a bench get hot in the system’s monitoring, based on predefined alerts, which told us a bench fan was broken.” Hooking up a lot of these nodes and sensors with IoT and their platform allows the grower to get real-time monitoring on the entire operation, from anywhere with an Internet connection.

Droller says using more and more sensors creates super high-density data, which translates to being able to see a problem quickly and regroup on the fly. “Cannabis growers need to maintain ideal conditions, usually they do that with a handful of sensors right now,” says Droller. “They get peace of mind based on two or three sensors sending data points back. Our technology scales to the plant and bench level, connecting all of the aggregate data in one automated system.”

In the future, urban-gro is anticipating this will lay the groundwork for using artificial intelligence to learn when controls need to be adjusted based on the monitoring. Droller hopes to see the data from environmental conditions mapped with yield and by strain type, which could allow for ultra-precise breeding based on environmental conditions. “As we add more and more data and develop the platform further, we can deliver some elements of AI in the future, with increased controls and more scientific data,” says Droller.

Pest problems in cultivating cannabis such as spider mites and powdery mildew are major concerns facing growers on a daily basis. Colorado’s ongoing recalls for cannabis products containing pesticides serve as a reminder that pest problems continue to plague growers. Utilizing integrated pest management (IPM) can help reduce the need to use any pesticides, as well as mitigate the risk of unwanted pests wreaking havoc on a cannabis harvest. urban-gro, a solutions provider for commercial cannabis cultivation, builds IPM plans for large-scale cannabis growers tailored to meet specific needs in regulatory compliance for different states.

Biological controls are essential to any proper IPM solution for growers. Beneficial living organisms such as insects, mites, nematodes or entomopathogenic fungi can all be applied as a method for controlling pests. Biological controls like those can reduce the need to use pesticides on cannabis. John Chandler, vice president of cultivation technologies at urban-gro, believes IPM requires a broad, systematic approach to eliminate the need for pesticides. “IPM is a combination of cultural, chemical and biological control,” says Chandler. “We start by evaluating the air flow of the facility, how plants are transported, any exclusion barriers and air filtration.” A robust IPM plan begins in the design phase of a new facility. “We can make key adjustments in floor plans, layouts and mechanical systems to optimize that first line of defense that is critical to mitigating the risk of pest issues.” Incorporating good agricultural practices can also help mitigate those risks.

“We help develop standard operating procedures with good agricultural practices in mind, including preventing cross contamination, which is the biggest pest issue facing cannabis growers,” says Chandler. “I encourage clients to set up harvest and vegetative rooms so that the plants are moving in one specific direction between rooms rather than back and forth.” Using positive air pressure with proper ventilation can further prevent cross contamination. Chandler also recommends scrubbing air coming into the building with gaseous hydrogen peroxide to keep filtering air in ventilation.

IPM plans require thinking in terms of systems to find the right balance of biological controls.

According to Mark Doherty, director of sales at urban-gro, their IPM plans are customized to meet different states’ rules and regulations, including each list of approved pesticides. “We work to design a system that meets each individual grower’s needs, while helping them navigate regulations in any given state,” says Doherty. “It is important to make cannabis safe for patients and IPM is critical in building a healthy ecosystem for plants to be grown in a safe, yet cost-effective manner.” Proper use of IPM can reduce the need to use pesticides, which could impact a cultivator’s bottom line, but ultimately protect patients’ wellbeing by providing safe and pesticide-free cannabis.

When all else fails and pests still find their way onto cannabis, there is a solution to address major losses. urban-gro distributes a product called Procidic2®, a broad-spectrum bactericide and fungicide compound, manufactured by Greenspire Global. The advanced commercial formula is designed to eliminate pathogenic bacteria and fungi. Procidic2® can be applied as a preventive and a curative. WSDA Organic Program has approved Procidic2® for use in organic agriculture production and handling. According to Steve Knauss, president of Greenspire Global, “Procidic2® works in sync with the plant through two modes of action: First it controls powdery mildew and gray mold on contact, and secondly it is absorbed systemically into the plant to control disease infection such as root rot,” says Knauss.

Implementing a comprehensive IPM system requires making key changes in cultural, biological and chemical controls. In doing so, growers can successfully mitigate the risk of pest problems, thus reducing the need for potentially harmful pesticides.
