Your Cultivation Plan is the Most Important Factor to Increase Your Yield

By David Perkins

Having a well-built grow room with adequate lighting, the ability to properly control the environment, proper nutrient feedings, a good pest management plan, well trained employees and an experienced cultivation manager are very important to the overall output of cannabis plants. However, even if you have all those measures in place, there’s no guarantee of success. One factor that is often overlooked is how many harvests you can get per year, as clearly the more harvests you can get in a given time period, the more likely your chances of success are in this competitive industry. This is why having a good cultivation plan in place, with proper foresight and planning, is so essential to success.

Increasing yield or production output in a cannabis cultivation facility can often be as simple as having the right cultivation plan in place to ensure that you are harvesting the maximum number of times per year. All it requires is a well thought out plan, and best of all, that does not cost any money if you have someone with enough cultivation experience assisting you and will earn back more than the cost of paying a consultant to get such a plan in place.

In this article I will explain why changing nutrients, grow media or even a cultivation manager may not necessarily increase yield, quality or your chance of success. What you should be focusing on is your cultivation plan and the scheduling of your cultivation cycles.

Why changing nutrient companies may not necessarily increase your yield

Nutrient dosers are used to inject fertilizer directly into irrigation lines

For the most part, nutrient companies use the same ingredients in their product lines and often buy them from the same source, but they combine them in different forms and ratios to create their “unique” product. You can go to a grow store, pick five different nutrient products, read the labels and compare the different nutrients in each one. You will find for the most part that they are very similar. Generally speaking, you could pick any one of those five nutrient companies and have great results. Mixing nutrients into a nutrient tank needs to be done precisely and if your employees are not doing it properly this can lead to plant health issues. In larger cultivation facilities, often nutrient dosers are used to inject fertilizer into the irrigation lines without having to mix nutrients. However, if the dosers are not set to the proper ratios, this can also lead to plant health issues.

There are a few companies that I really like that have a different approach to plant nutrition, which saves time and can prevent human error associated with mixing and applying liquid nutrients. Soilscape solutions, Organics Alive and Beanstock Agriculture all have nutrient lines that are intended to be used with soil or soilless media that can be amended into the soil which provide a slow steady release of nutrients that the plants can uptake as needed. This avoids the risk of human error in repeatedly applying liquid nutrients to the plants.

Why changing grow medium and nutrients will not necessarily improve your yield but may increase yourquality

Whether it is rock wool, coco fiber, a soilless mix or living soil, everything has a limit. Giving your plants the proper amount of water and the frequency at which you water, along with having sufficient room for the roots to grow are key factors to ensuring plant health. If your plants aren’t getting watered properly, no matter what media you are growing in, you will be having problems. Changing things like grow media won’t result in instant success, as there will always be a learning curve when making changes to your cultivation. If you cannot adapt quickly enough, you can quickly create major problems.

plebanisoil — Changing things like grow media won’t result in instant success, as there will always be a learning curve when making changes to your cultivation.

You would be better off to master the grow media you are currently working; you will have more chance of success making slight alterations to your current media than you will if you switch your grow media altogether. There are so many different nutrient lines, soil companies, coco coir companies and the truth is any of them can lead to success.

Changing grow media and nutrients do play a large role in quality though. With cannabis being legalized in many states, the overall quality of cultivation inputs have increased, especially nutrients. However, in general, with some exceptions, the quality of cannabis has not necessarily increased along with the increase in quality of nutrients. One exception: I would argue that switching from salt nutrients and rock wool, to organic living soil will result in an improvement to the flavor, quality and terpenes of the cannabis.

A lot of people use rock wool with salts because it’s easier to scale up than if you are growing in soil, but some quality is also sacrificed. Soil is heavy and messy and most people throw their soil away which takes a lot of money and labor to do. Reusing your soil is one of the best ways to save time, money and increase quality. I had a friend that grew the same variety, same lights, same ventilation but grew hydroponically with salt-based nutrients and he would always say the cannabis I grew, organically, tasted better. The same was true when we grew the same variety outdoors. He used salt-based fertilizer, I used amended soil with water. There wasn’t really a comparison in flavor and the yield was not compromised either! This was his opinion not mine.

I think the vast majority of consumers have not seen the type of quality that someone in Northern California who has been smoking and growing for 20 plus years has seen. Quality is relative to what you have been able to acquire. Most people especially nowadays will never see the quality that used to be common when we didn’t treat the sacred herb like a commodity. When you do it for the love of the plant it shows. Remember, quality is relative to your experience and if salty weed is all you know, you are probably missing out.

Why changing your Cultivation manager may not necessarily increase your yield

Every cultivation facility should have an experienced cultivation manager who is knowledgeable in the areas of nutrient requirements, pest management, environmental requirements, managing employees and overall facilities operations. If a grow room cannot sustain the proper environmental set points, blaming the problems and issues that arise on the cultivation manager is not fair. It is a common problem in the cannabis industry – the owners of a company are not seeing the results that they want and think that by replacing the cultivation manager it will solve all their problems. In reality, often the problem results from upper management or owners of the company not providing the cultivation manager the tools necessary to perform their job at the highest level. Another common problem is when owners fire the cultivation manager and replace them with lower-level employees to manage the facility. The problem with this is those employees do not have enough experience nor the attention to detail to successfully run a cultivation facility. The result is that yield and quality suffer tremendously.

You should be harvesting every 60-70 days

If you are cultivating strains that finish flowering in 60 to 70 days you should be getting five harvests per year.

The reality is there is no one specific thing you can try or buy that will result in success. It is everything combined, the HVAC system, lights, genetics being grown, water quality, air quality, root zone temperature, ability to control environment, having a clean facility, disease free plants, knowledgeable cultivation manager etc. that are required to operate a successful cultivation.

But all of that is less important to yield than a good cultivation plan. Cultivation methods directly tie into the overall production of a facility. But, regardless of whether you’re growing in soil, hydroponics, using LED or HPS, have low or high plant counts, if you don’t have the ability to harvest a grow room, clean and replant within a very short amount of time (ideally one or two days) then you’re going to be losing out on profit.

If you’re cultivating strains that finish flowering in under 60 days you should be getting six harvests per year. If you are cultivating strains that finish flowering in 60 to 70 days you should be getting five harvests per year. To do this, you will need to have the appropriate amount of plants that are ready to be flowered to refill your grow room or greenhouse ready to flower. With a little bit of planning and foresight you will be able to do this, and you will be on your way to producing your highest yield potential.

If you are struggling to have enough plants that are ready to flower once you are done harvesting and cleaning your grow room, having trouble planning your cultivation schedule to maximize production, or struggling to maintain a mother and clone room to supply your own plants or planning for the appropriate amount of labor, contact Floresco Consulting and talk with one of our cultivation advisors to get you back on track. We can guide you to ensure you are harvesting, cleaning and replanting every 60 days. Contact us today to get your facility producing at its maximum potential.

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?

A facility that Andras designed in Massachusetts

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.

A California cultivation facility he designed

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.

Too Many Cannabis Firms Put Sustainability in Last Place

By Mitesh Makwana

No Comments

Cannabis has long been considered a green industry by the masses.

As a standalone item, the cannabis plant is very environmentally friendly. This is particularly true when it comes to hemp, a variety of the cannabis plant with a huge range of environmental benefits. An extremely versatile and robust crop, hemp uses far less land and water than other common crops and even captures carbon dioxide and regenerates soil. Approximately 20,000 products can be made from its seed, fiber and flower, from biodegradable plastics to food supplements, meaning all in all – it is an environmentally and economically sustainable crop

Yet as with most things, when cultivated in mass, the cannabis plant isn’t quite so green anymore. With its high demand for water, land and artificial lighting, cannabis cultivation can actually leave a large environmental footprint (this does however, pale in comparison to the food industry).

What’s more, many firms do not properly understand how to correctly treat and apply chemical fertilizers and pesticides, and use a machine gun approach to growing their crops. This can result in unnecessary bleed waste, which in turn can kill micro-organisms and contaminate soil, water and other vegetation. Packaging has also been cited as particularly environmentally unfriendly in the cannabis industry, with several organizations using single use plastic for their products, due to the strict guidelines attached to packaging products of a medical or pharmaceutical nature.

A field of hemp plants, (Cannabis sativa L.)

So as the CBD, medical and even adult use cannabis industries become increasingly commercialized across the globe, there is risk cannabis might start moving in the wrong direction when it comes to sustainability.

Still relatively new, the cannabis sector is nascent and exciting, with the global cannabis market size valued at $10.60 billion in 2018 and projected to reach $97.35 billion by the end of 2026. Yet as the industry grows, so too will its footprint.

I’ve seen it first-hand. The industry being hugely competitive, so for companies vying for precious investment and fighting for a spot on the stock market, often, sustainability is the last thing on their minds. In my opinion, this is wrong. Not only morally – we all play a part in looking after our planet – but it’s also a poorly calculated business decision.

It’s no secret sustainability and ESG have become a hot topic when it comes to investing. Just yesterday, Credit Suisse told CNBC that the pandemic has accelerated the trend towards sustainable investments. The bank has even introduced an exclusion strategy whereby those investing can actively exclude controversial sectors.

So with the environment firmly on investors’ minds, cannabis firms need to realize that actually, if they want to secure the support of forward-thinking shareholders, they need to consider more than just the bottom line and truly take the sustainability of their operations into account.

Luckily, there are practices which cannabis cultivators can take on board to reduce their environmental footprint. To start with – growing outdoors. This enables cannabis farmers to harness the sun’s natural power, saving them money on electricity bills and increasing energy efficiency. With cannabis being a rather thirsty plant, water use is also a major concern – although this is nothing compared to the amount of water used by cotton plants. However, it is in fact possible to design indoor operations which recycle close to 100% of the water use, including capturing the perspiration from plants – at AltoVerde this is something we are looking to implement in our upcoming Macedonian sites.

Firms keen to improve on sustainability should also cultivate in a way in which soil is fully replenished and repaired after use – this is called regenerative farming, and it’s extremely effective for maintaining and improving soil quality, biodiversity and crop yields. Another interesting concept is the use of hemp. Some farmers have started using hempcrete – a concrete-like material made from harvested cannabis plants. As if the recycling aspect wasn’t good enough, hempcrete is actually carbon negative, meaning the production of hemp for hempcrete removes more carbon from the atmosphere than it produces.

It’s been incredibly exciting to be a part of the cannabis industry and I am excited to watch its growth in the years to come. It’s taken hard work for the sector to improve its traditionally poor image and to be accepted across the globe, so now, cultivators must lead by example and stop industry from being branded as one which pollutes. By transitioning to more environmentally sustainable practices, firms will be doing their bit for the planet, attracting the investors of tomorrow and ensuring their own success for years to come.

Essential Elements to Set Up a Green, Zero-Waste Grow Facility

By Anthony Franciosi

1 Comment

Clean, ecologically sound production methods are the ideal for any cultivation or farming activity. Taking from the earth only what is needed to grow the crop and leaving behind little in the way of chemicals and land/water loss is the goal; with cannabis grow facilities, it can also be a reality.

This type of production does require some capital investment into state-of-the-art equipment and facilities, with standards that are equal to or even surpass current EPA and USDA regulations. While cannabis growing does not yet have access to the organic certification, that doesn’t mean growers can’t abide by and even go beyond the rules, to grow clean, healthy and environmentally sound cannabis.

There are a few essential elements required to make this kind of operation a reality.

Ecologically advanced use of power

For any indoor facility, one of the key elements is lighting. Using as energy efficient a system as possible is key. The best option at the moment is LEC lighting, which provides a spectrum of light that is very close to natural. This makes checking on plant progress more realistic and, with the inclusion of UV-B in the spectrum, can improve yields as well. In addition, the LEC bulbs have a long life—up to 2 years—which means lower maintenance costs as well.
The demand for high-quality, organically grown cannabis continues to increase

Another aspect of growing that tends to use a lot of power is the cooling system. A standard HVAC system will be power intensive, so alternative ones like water chilled climate control systems are just as effective and 30% more power efficient. These systems are also able to reuse wasted power by feeding it back into the system, creating an additional 10% energy reduction. In addition, when the outdoor air temperature dips below 45 degrees, a water chilled system can switch to using the outside air, creating 60—70% in energy savings.

Efficient management of water resources

Cultivators depend heavily on water to ensure that the plants are hydrated and able to absorb the nutrients they need to grow and thrive. The result for many however is an excessive waste of water. This is a problem when a grow facility is leveraging municipal water resources. A water meter helps to manage and track usage but to ensure that it is used as efficiently as possible, a “top feeding” method of usage ensures minimal water waste (5% or less).

Effective waste management

Wastewater is a byproduct of any water intensive cultivation method but there again, managing the systems to ensure that what water isn’t reused and becomes “gray water” is still as clean as possible is the ideal. A high-quality filtration system keeps sediment, chlorine and other harmful elements out of the water supply — and out of the municipal sewage system. Further, by using organic matter throughout the growing process, the wastewater that is produced will meet every federal standard for organic food production.
All plant waste in a grow facility—for example: stems and fan leaves—is disposed of according to state and local laws. With cannabis plants, that requires a certain level of security, including locked dumpsters that are only unlocked and placed outside when the removal trucks arrive on site.

Organic farming practices

Using OMRI (Organic Materials Review Institute) listed soil is an essential part of clean, environmentally friendly growing. To ensure the proper nutrients are available for each harvest, once a crop is gathered, the soil is transferred to a local landscape company to compost and reuse.
Pesticides need to obviously be avoided and all fertilizers need to be USDA approved as organic and all nutrients need to be certified by OMRI to ensure they don’t contain any synthetic materials.

Considering all of these aspects is essential to creating an ecologically friendly grow facility with tremendous yields that are clean and safe for the end consumer, as well as minimizing the impact to the earth.

Designing Precision Cannabis Facilities: A Case Study

By Phil Gibson

No Comments

With data forecasting expert BDSA predicting that the global cannabis market will reach $56B by 2026, there is no time to waste. Whether it’s Oklahoma, New York or even Macedonia, the frenzy is on. Investment decisions are immediate, and you have to be correct out of the box. This is where an expert like Andrew Lange and his company, Ascendant Management, come in. Andrew has designed more than 1.5 million square feet of cannabis facilities and moved them into profitable production in North America and Europe. One of his active customers is Onyx Agronomics in Washington. Bailee Syrek is the director of operations at Onyx and this is the story of the key points in designing a precision cannabis facility with state-of-the-art efficiency.

Background

Andrew Lange, a navy veteran, runs a global cannabis consulting business based in Washington. With a “prove it to me” approach, he regularly tests the best new technologies in the facilities he designs. He integrates his knowledge of what works in practice into his subsequent facilities. One of his previous projects, Onyx Agronomics in Washington, started in 2014 and moved quickly into production in a retrofitted warehouse. Many of his best ideas started with Onyx, including some new innovations in the latest expansion there this month. Onyx is a tier 3 cannabis cultivator.

Bailee Syrek’s operation at Onyx currently produces 9,000 lbs. of dry trim bud per year in 8,000 square feet of canopy. She operates the state-of-the-art, clean room style, indoor grow facility around the clock, delivering 2.7 grams/watt from every square foot of canopy in her building. She runs a highly efficient facility.

Onyx has had an ongoing relationship with Ascendant Management and chose to leverage them again with their current expansion to increase their capacity further. Onyx uses a range of advanced technologies including aeroponic cultivation equipment and control software from AEssenseGrows to hit their metrics.

Precision, Quality & Consistency

“I look for ways that my clients can differentiate themselves,” says Lange. Maybe it’s his military background, but Andrew demands precision, quality and consistency in the operations he designs. “Cannabis is a just a plant really so we look for the highest performance grow methodology. I find that to be AEssenseGrows aeroponics,” says Lange. “The AEtrium Systems provides a good foundation to manipulate for grow recipes and business process. I add teamwork, communications, and operations procedures to that foundation.”

At Onyx, Bailee Syrek works closely with her channels. She invites her customers in regularly to review the Onyx cultivars and to cover their ideal requirements. These can range from bud size for their packaging to THC or terpene profiles (Yes, channels do want both higher and lower THC content for different consumers and price points). Based on that feedback, Bailee and Andrew work together to dial in the ideal grow recipe in the AEssenseGrows Guardian Grow Manager central control software. They push their target strains to optimize the results in the direction requested by their customers. For example, “How do you get the highest possible THC out of 9lb Hammer?” You’ll have to ask Andrew and Ascendant Management.

Driven by customer requests, Onyx is adding new strains to build on their innovative brand. Bailee expects to reach new levels of terpene bundles with Cheeseburger Jones, Koffee Breath, Shangri-La and OK Boomer. Utilizing Andrew’s expert knowledge, they can take typical sub-20% cannabinoid bundles and improve them using aeroponics and better controls, into standout aeroponic 30% packages.

The Onyx Vision

Bailee Syrek believes this is the most exciting time yet for Onyx. Delivering premium grade cannabis as a white label flower supplier for years, Onyx is a profitable and successful business. But even with doubling capacity every year, they are still having trouble keeping up with customer demand. Bailee wants to get to the point where she can always say yes and accept an order from their white label customers. With this objective, she again engaged Ascendant and Andrew to get beyond 15,000 lbs. of output in 2021 to make her customers happier. Beyond that basic expansion, she is also ambitious and is preparing plans for additional lines of revenue with their own proprietary flower, oil and derivative products.

“This expansion will be a new challenge,” says Syrek. “Flower production is in our wheelhouse. We have tighter operations, with the most consistent bud size, terpenes and test results in our state. These new products will require that same quality but now in new areas.”

Her Path to Leadership

Bailee started with Onyx in a compliance position that grew out of the constant demands for government licensing and reporting. In that compliance role, she had the opportunity to work a bit in every department, giving her a good understanding of all of the facility operations and workflows. All of that experience led her to eventually take over the operations leadership role. She instills care and effort to maintain the cleanest and most efficient operations possible. “With aeroponics, we don’t have to lug soil from room to room or in and out of the facility. This saves us a ton of work that we can redirect to plant health and maintenance,” says Syrek. “Medical precision and GMP quality is a given. Each room on average is 105 lights and one room manager and one cultivation technician take the room from clone/veg transfer to harvest as a two-person team.”

Bailee Syrek, director of operations at Onyx Agronomics

Bailee prides herself with results. “Medical grade precision is normal for us. We use medical grade SOPs for every aspect of our production.” Bailee has designed these guides into their control system that runs on the Guardian Grow Manager software. From sensor tracking, to performance graphs to time cards; everything is integrated in her performance monitoring.

A quality focus is very apparent in every Onyx flower room. Every watt of light energy is transferred to the pristinely manicured canopy. Naked stems feed nutrients up to the fat buds at the trained canopy surface. Fan leaves are removed and all possible energy turns into bud weight and potency. The room technician has a passion for plant health, table care and plant maintenance all the way through to the harvest bonanza.

What is the biggest challenge for Bailee as she drives the operation? Even at 105-110 grams per square foot per harvest, they are sold out. “Every customer wants to buy beyond our capacity. It is a good problem to have,” Bailee says. “Customers want our quality and love the consistency. This is the most exciting thing about our expansion. We will finally be able to make additional channels happy with high quality supply.”

This is where Andrew credits Onyx’s performance. “Most well running operations deliver 1.1-1.8 grams of dry trim bud per watt of electricity used in powering a grow room,” says Andrew. The Onyx grow formula results leave this in the dust. Running Fluence SPYDR 2i grow lights and the AEtrium System aeroponics, Onyx plants are delivering just shy of 4 lbs. per light with every harvest cycle. At 630 watts max output, that delivers ~2.7 grams/Watt, the most efficient operation he has seen. The Onyx process and execution works.

“Bailee is a great example as a professional. She builds a motivated team that executes better than her competition,” says Andrew.

At the same time, Onyx runs a highly space efficient nursery with just enough mother plants feeding energetic cuttings into the 4-layer stacked AEtrium-2.1 SmartFarms in their environmentally controlled clone room. They produce more than enough healthy clones to jump from veg to flower in the span of a week. Grow time, harvest turn time and no veg space, results in very efficient use of power in the complete operation.

Mirroring Onyx for Medical Grade Cannabis in Europe

Andrew Lange’s current passion is a green-field project in Portugal. Self-funded, Andrew says that this facility will be one of the first that is pure enough in operations to supply non-irradiated clean-room-level-quality cannabis beyond the precise standards required by European regulators. Current importers have not been able to clear the European standards for cleanliness without irradiating their buds. Other companies like Aurora have abandoned efforts to access the market due to the precision requirements. Typical methods used for fruit imports use gamma radiation to get bacterial counts down. This was tried with cannabis to sterilize buds, but the problem with cannabis is this degrades the quality of the flower.

Andrew’s Portugal facility will be using a sterile perimeter surrounding his grow space (mothers, clones/veg, flower rooms) and harvest and processing areas (dry, trim, packaging). Andrew creates a safe environment for healthy production. A steady harvest cleaning regimen is built into his operational designs from the beginning. All operators are trained in procedures to exclude pathogens and limit all possible transmission (airborne, physical/mechanical touching, or water carried). Every area is cleaned during and between harvests. Andrew is confident he will reach a consistent level of accuracy and purity beyond European requirements because it is routine in all of his designs.

Certified Efficiency is the Message

Good Manufacturing Practices (GMP) and Good Agricultural and Collection Practices (GACP) are required for certification and access to European markets. Andrew always builds tight operations, but in this case, his Portugal facility is designed with the fit and finish to be GMP and GACP compliant from day one with advanced air filtration and air management throughout.

Automated aeroponics is a foundation technology that Andrew recommends for his facility designs. The automatic data logging, report generation, cloud access and storage make this a foundational technology. Andrew does get some resistance from cultivators that are used to the classic soil media approaches but he explains that software configurable grow recipes, precision controls, zero soil/no pests and hyper-fast growth makes aeroponics the foundation of competitive advantage. Precisely controlled medical quality precision operations are built on top of this foundation.

The initial phase of the Portugal facility is 630 lights and this facility is Andrew’s latest personal investment. From secure perimeters to modular grow rooms and highly automated equipment, this location will be state-of-the-art in terms of grams/watt yields and renewable energy with an output of 6 metric tons per year. Solar powered electricity from a 4-megawatt farm will use Tesla megapacks for storage and be grid independent.

Technology & Innovation, Onyx & Ascendant

From his first experience with AEssenseGrows aeroponics, Andrew has been able to design complete grow recipes in the Guardian Grow Manager software with very tight precision on dosage. This makes it possible to create ideal recipes for each strain (nutrition, irrigation cycles, lighting and environmental management). This frees up the operations teams to focus on plant health and execution. The nutrients, pH, CO2, temperature and humidity, follow the Guardian directions that he sets.

Working with Bailee at Onyx, Andrew is now consulting on the post-harvesting side of operations (drying, trimming, extracts and packaging). In parallel with his efforts, Bailee is optimizing THC & terpene production on the cultivation side with UV lighting (considering far-right red frequency light recipe enhancements).

That is the Ascendant Management approach to innovation. Trial, test constantly, perfect ideas in practice. Optimize the results for consistent, high-quality results. Even while driving for the personal craft touch, use automation to increase efficiency of mundane, but important tasks. With these methods, Andrew believes that the Onyx labor cost is one third of typical soil media grow operations. Zero soil aeroponics offers many benefits. Bailee’s team is able to give each plant more attention and delivery better quality. Automation is a win-win for them.

Bailee finds that constant testing is useful for two things: one, great results, and two, surface the best talent with their hand’s-on approach.

Always Finish with People

Bailee says that her staff works incredibly hard. “We are a different grow, with better ergonomics on the job, aeroponics for precision and yields, and advanced technology at the leading edge in every part of our grow. No dirt up and down stairs. People are proud to work here. We are not your dad’s grow operation.”

“We promote from within. Everyone starts as a room tech and has the opportunity to move up. Teams are isolated by rooms so there is no contamination between rooms or humans. Put in the work, and you will get promoted with expansions, and grow with the company as we take a bigger share in the market.” Female employees make up almost half of the current staff, and Bailee encourages employees to refer their friends. “Good people invite good people,” she says.

Her training program introduces the technical aspects of their unique operation, the positive expectations and career path for every new employee. The social environment is friendly with good pay and regular raises. Each new employee fills a range of roles during their 1-month training circuit and are assigned to a cultivation space under a lead as an official cultivation tech at the end of 30 days. “One thing that we do more than at other grows is constant cleaning,” says Bailee. “This is an ever-present mantra for the staff.”

Flower-Side Chats Part 2: A Q&A with Bill Conkling, Founder and CEO of Maggie’s Farm

By Aaron Green

No Comments

Flower continues to be the dominant product category in US cannabis sales. In this “Flower-Side Chats” series of articles, Green interviews integrated cannabis companies and flower brands that are bringing unique business models to the industry. Particular attention is focused on how these businesses navigate a rapidly changing landscape of regulatory, supply chain and consumer demand.

Maggie’s Farm is an integrated cannabis company based in Southern Colorado. Maggie’s Farm has seven adult-use and medical dispensaries and cultivates the vast majority of their flower on outdoor farms. All Maggie’s Farm products are sun-grown from seed in soil that is 100% custom-mixed onsite as well as spring-watered, slow-cured and hand-trimmed. Maggie’s Farm does not use any synthetic pesticides or growth hormones in its cultivation. In addition, for the past eight years, Maggie’s Farm has recently obtained Clean Green Certified®, a designation certifying organic standards and testing that mirrors the USDA organic certification. Maggie’s Farm was the first cultivator in Colorado to earn the Clean Green certification.

We spoke with Bill Conkling, Founder and CEO of Maggie’s Farm to learn more about the benefits of outdoor growing, localism and their Clean Green certification. Bill started Maggie’s Farm in 2010 after growing up on cattle ranches and farms in Colorado.

Aaron Green: Bill, thanks for taking the time today. Tell me a bit about how you got involved in the cannabis industry.

Bill Conkling: I am a native of southern Colorado. I was a medical caregiver back in the early days of legalization, and I saw an opportunity to vertically align after my first legal crop in 2010. I opened up the store in 2011. I’ve been a lifelong proponent of medical, recreational and adult use of marijuana.

I come from a background of farmers and I had worked on cattle ranches and farms throughout childhood. As soon as I graduated from college, I went back to work on a large cattle ranch in the four corners area [of southern Colorado]. That’s where I started to incorporate my indoor cultivation experience and skills with outdoor.

Aaron: What trends are you following in the cannabis industry?

Bill: I was one of the first medical operators to support legalization, so I have certainly followed legalization trends. I’ve looked at some other states in our region in terms of growth and legalization.

Bill Conkling, Founder and CEO of Maggie’s Farm

We’re trying to stay a regional supplier and producer so that we are locally grown. We believe the southwest of Colorado is optimal for outdoor cannabis cultivation.

At Maggie’s Farm, we have followed an organic trend from the beginning and I think that’s becoming more of a trend now. We recently received Clean Green certification to that effect. Our goal is to try to provide the healthiest product at a good value to the market.

I believe that all of the products that are made in the cannabis world come from the flower. Downstream products are only as good as their ingredients. It all starts with the flower. So, we focus on producing a clean, top-shelf quality flower that is produced outdoors.

Aaron: How do you define local?

Bill: Local is staying in the climate that is optimal with the least amount of carbon footprint to the earth. That also means trying to operate so that we’re not moving a lot of product across long distances.

We’re trying to set up farms that are in optimal climates. There is a two or three-state region that I believe is the optimal climate for outdoor marijuana cultivation in our country.

Aaron: What states are those specifically?

Bill: I think Colorado and New Mexico, primarily.

Aaron: What geographies is Maggie’s farm currently in?

Bill: We’re in southern Colorado. We don’t go into the plains of Colorado.

Aaron: So Colorado state only right now?

Bill: Yes. The wet mountain range is one of the mountain ranges that we are in. I’ve also cultivated in the La Plata mountain range.

Aaron: What specifically is it about that region that makes it conducive to cannabis growing?

Bill: I think if you get the right elevation and the right microclimates within those elevations, and you have the number of sunny days that Colorado offers in those areas – the intensity of the sunlight, and the cool nights – all those things are factors that coincide in these areas that we like to cultivate in.

Aaron: We’ve been talking about outdoor growth. Does Maggie’s do any indoor?

Bill: No. We’re essentially an outdoor farm. We do a little bit of breeding and we’ve got starter houses, greenhouses and hoop houses for that purpose. We’ve got one greenhouse that we use for some wholesale, but we are primarily outdoors.

Aaron: How do you go about selecting the genetics or evolving the genetics to meet your local environment, given that you’re growing outdoors?

Bill: A lot of it is honestly through testing and experimentation, historically. You just cultivate and harvest and see how the genetics performed, you know? You test, you take test inputs, you take customer reviews, and blind test results from the team and from the customers and you consider all those facts.

Aaron: Do you produce and use your own seeds or are you purchasing those?

Bill: We have done both. I think I’ve probably created somewhere north of 800 different strains at this point. So, we’ve got a huge seed bank. We do also buy from vendors and experiment with some of those genetics as well.

Aaron: Do you market your seeds in Colorado?“I don’t think that you can get anywhere near the terpene value indoors that you can outdoors.”

Bill: We do not.

Aaron: How did you settle on outdoor-only as the strategy for Maggie’s?

Bill: I believe outdoor is a premium flower. I think it has less impact on the earth. I think that there is a lot less pest mitigation than there is indoors, which makes it a healthier, cleaner product. You don’t have to mitigate the concentration of pests that you get in temperate climates of stagnant corners of greenhouses and buildings that you cultivate indoors. Therefore, you never get into the situations as often or as intensely, where you might have to really work hard at mitigating your pests. You can use the natural predator insects you can introduce and oftentimes they survive and they create their own climates and it’s a more natural, healthier product.

I don’t think that you can get anywhere near the terpene value indoors that you can outdoors. You just don’t have the value of the sun, which nothing compares to. You can hold up as many high wattage bulbs as you want and you don’t even pale to the sun and the effect that the sun has on the flower.

Aaron: What are some of the challenges of growing outdoors that you see frequently?

Bill: You have to be nimble. You can’t rely completely on a schedule. You’ve got to be able to shift around in your planting days and your harvest dates.

You’ve obviously got to be on your toes all the time for weather changes. Higher humidity years can tend to bring more insects or pests. Some years you’ve got higher winds than other years. This year, we had a snowstorm on September 9, which left nine inches of heavy wet snow on one of our farms. So, you’ve got to be nimble, very proactive and ready for those kinds of weather events that happen in very short notice.

Aaron: We mentioned Clean Green Certified® briefly. Can you explain more about the Clean Green certification and why that’s an important thing for you at Maggie’s?

Bill: The choice to become Clean Green Certified® was really an effort to validate the organic process that we have. We vetted out what we believe was and still is the premier, organic criteria certification endorsement in the market for cannabis. To this day, they really do an ethical, vetting-out process whereby if you fail the parts of any of the soils that are sent to federal-licensed labs, you do not get your endorsement. The owner of Clean Green also had a mother company that was an endorser of other agricultural products such as coffee, wheat and dairy.

Aaron: How would you compare Clean Green Certified® to USDA Organic?

Bill: Identical. When the federal government legalizes, we are poised to automatically convert to a USDA Organic certification and endorsement. The processes the founder and owner of Clean Green uses to test cannabis is the same process used to test other agricultural industries. For plants, he takes random samples of soils throughout a cultivation field and sends them to a federal-licensed lab where they test for impurities.

Aaron: Did you decide to get your Clean Green certification due to pulling from the market, or is this more something you decided to do internally as Maggie’s Farm?

Bill: I decided to do this internally. I wanted to be recognized for all of our organic efforts and I wanted to let people know that we have a safe product that doesn’t have synthetics in it. Even to this day, a lot of people in Colorado unlike the coastal states like maybe California are still pretty unaware of a Clean Green certification or even the fact that there is an organic process for cannabis or marijuana. So, it’s really just to let our customers know that there is value in a safe, healthy choice for them.

Aaron: What kind of products do you create at Maggie’s farm?

Bill: We grow flower. We are also a big producer of a very high-quality pre-roll. We are developing promoted products as well.

Aaron: Do you do fresh frozen?

Bill: We do some, yes.

Aaron: Are you selling direct to the dispensary or to manufacturers?

Bill: We finally had produced some excess. So, we started wholesaling flower this year and lots of high-quality shake for concentrates to concentrate makers. Our customer is typically a little more of a mature customer. I don’t want to say necessarily older, but I think we probably do hit a little bit of a higher, more experienced, health-conscious, connoisseur customer.

Aaron: Can you give me an idea of some of the regulatory challenges in Colorado that you’ve faced in the past or are facing today?

Bill: The perpetual change of regulation has been a challenge. Being a competent operator in cannabis means getting used to the change and having the resources to be nimble with compliance. We haven’t had common problems such as metals, mold or mildew issues. However, we have had some hardware issues, which required us to change cameras along with other technical intricacies.

Aaron: How many acres do you have?

Bill: We have about 30 acres of secured premise cultivation.

Aaron: Is that all managed in-house or sublet?

Bill: It’s all managed and operated exclusively by Maggie’s Farm.

Aaron: What’s next for Maggie’s Farm? What are you excited about?

Bill: We want to continue to put a higher scale of a very healthy, quality, value flower out there and to be able to offer that to more states initially states that are within our region and eventually states across the US. Also, we will continue to do our best to meet the growing demand for healthier choices in general.

Aaron: Lastly, what are you personally interested in learning more about?

Bill: How we can continue to be as earth-conscious as we can be? How we can continue to look for ways to give back to our communities? How we can continue to operate as a view of made in the USA and to try to just support local regional and national products and vendors? Just how to be more aware and always look for opportunities for self-improvement.

Aaron: That concludes the interview, thank you Bill!

UT-Arlington and UT-El Paso to Evaluate Phytochrome Manipulation in Hemp

By Cannabis Industry Journal Staff

No Comments

The Collaborative Laboratories for Environmental Analysis and Remediation (CLEAR) at the University of Texas at Arlington (UT-Arlington) and the University of Texas at El Paso (UT-El Paso) has begun collaborating with Curtis Mathes Grow Lights (CMGL), a subsidiary of the Curtis Mathes Corporation, and the hemp genetics company ZED Therapeutics. The research will involve characterizing the phytochemical effects of phytochrome manipulation using various LED horticultural lights of differing light spectrum, and novel high-yielding varietals of hemp. All of the hemp plants will be grown by renowned geneticists Adam Jacques, Christian West, and Oriah Love of ZED Therapeutics under the CMGL Harvester LED lights at their Oregon facility. Drs. Kevin Schug and Zacariah Hildenbrand will oversee the analysis of the corresponding samples for the expression of terpenes, flavonoids, and other classes of therapeutic compounds. The expression of 15 primary cannabinoid species will be performed concurrently by Matthew Spurlock of ZED Therapeutics.

“Since its inception, CLEAR has focused almost exclusively on improving environmental stewardship in the energy sector. It is nice to now diversify into the horticultural industry to better understand how chemically-diverse plants like hemp respond to different environmental-friendly LED lights,” says Professor Kevin Schug, Shimadzu Distinguished Professor of Analytical Chemistry and co-founder and the Director of CLEAR.

Hemp has recently garnered significant attention in the mainstream media as a result of the medicinal benefits of its primary natural constituent, CBD. The collaboration amongst UT-Arlington, UT-El Paso, CMGL and ZED Therapeutics is designed to better understand how the variable of light can influence the expression of other medicinal elements.

“We are incredibly excited about our growing collaborations with UT-Arlington, UT-El Paso, and ZED Therapeutics,” says CMGL’s COO, Robert Manes, “This particular research exploring phytochrome manipulation in hemp may unlock new lighting protocols whereby the modulation of different wavelengths is associated with the expression of different phytochemical profiles.”

This research also has the potential to discover novel molecules that may be present in the ZED Therapeutic hemp varietals using high-resolution exploratory instruments that are unique to the laboratories of CLEAR, such as Liquid Chromatography Quadrupole Time-of-Flight Mass Spectrometry (LC-QTOF-MS).

“We are always searching for new ways to expand our genetic catalogue and it will be interesting to see what sort of effects light modulation have on cannabinoid, terpene, and flavonoid expression,” says Adam Jacques of ZED Therapeutics, “Phytochrome manipulation, and any resulting epigenetic effects, is a poorly understood principle of horticulture and we see a significant opportunity with this research to unearth new knowledge.”

“Hemp is a unique plant both in its light spectrum adaptation and the wide range of phytochemicals it can potentially produce,” says Christian West of ZED Therapeutics, “I’ve been waiting my whole career to be a part of this research and having the lighting knowledge of CMGL combined with the analytical power of UT-Arlington and UT-El Paso is priceless in expanding our understanding of the plant.”

5 Factors to Keep in Mind When Entering the Regulated Market

By David Perkins

No Comments

It’s a different world growing cannabis in California- in fact, it’s a completely different experience than it was even four years ago. It can be overwhelming to begin the process, which is where an experienced cultivation consultant can help. This article will highlight 5 factors to keep in mind before you begin growing in California’s regulated recreational market.

Start Up – Costs, needs & endless variables

So you’ve decided to begin a recreational grow, here are the factors to consider before you get started.

Permitting, the necessary pre-cursor to cultivation, can be time- consuming, extremely expensive, and overwhelming. General experience dictates that any grow will take longer than planned and cost way more money than you ever expected or anticipated. Always account for more money and time than you think you need. Working with an experienced consultant can help you plan and account for all the costs and variables you may not have considered, prior to beginning cultivation, in order to ensure your success.

Understand that growing boutique style cannabis is very difficult on a large scale, consistently.

Equipment. When choosing what equipment to use, stick to reputable equipment manufacturers. Don’t just go with the latest high-tech gear because you see it on Instagram being advertised by a big, fancy grow operation. Stick to what you know best. Do your homework and research the equipment as much as possible, prior to purchase. Use equipment that has been tested and well documented with success. Some questions to ask yourself: is this necessary? Is it cost effective? Will it help me reach my goals?

Grow your business slowly and naturally. Getting too big too quick will most likely expose inefficiencies in your operating plan, which will be further compounded when production increases. Don’t sink before you can swim and start out on a massive scale before you have perfected your process.

Cultivation – It pays to design it right the first time

Success begins in the grow room. Never forget that. A properly engineered cultivation plan can be the difference between 3 and 6 harvests per year. Again, it is imperative here to do your homework. A well-thought-out plan can make or break you, and that is where an experienced cultivation consultant can help.

Set realistic expectations. Understand that growing boutique style cannabis is very difficult on a large scale, consistently. Don’t expect to grow perfect cannabis every time – it is unrealistic and can ultimately lead to failure if your financial model depends on it. Growing a plant, while mostly in your control, involves too many variables to rely on a perfect outcome round after round. You can do everything in your power, yet something unexpected can still happen and be detrimental to your yield, and therefore your profit. You must expect and plan for this.

Automating as much of your grow as possible is always a good idea. This will greatly reduce labor costs and more importantly, minimize human error. In some instances, it will even allow you to review data and information remotely, in real time, allowing you to ensure your cultivation site is always running as efficiently as possible, even when you aren’t there.

Processing – Don’t skimp on the process

If you are going to be harvesting cannabis for flower, it is imperative to have a properly built facility for drying, curing and storing your product. You must consider that this building will need to be large enough to house and properly store all of your harvest at once. This can make or break your crop at harvest time. If you don’t have the capacity to handle your harvest properly, it can lead to disastrous issues such as mold or too quick of a cure – conditions which make your cannabis unsellable in the regulated market.

Although costly, if done correctly, you can also design this area to serve as your propagation, trimming, and breeding areas, which will ultimately save on costs in the long run.

Also keep in mind, hand trimmed cannabis will always look more appealing to the consumer than machine trimmed cannabis. However, hand trimming can be time-consuming, labor-intensive, and therefore far more costly than machine trimming. These are factors you will need to consider and budget for when deciding how to proceed. If you use a machine, you may save money up front, but will you be able to sell your cannabis at full price?

Distribution – Have a plan

It is a good idea to have a plan for distribution, prior to start up. If you have an agreement with a retail outlet (or contract with a distributor) in writing, you will protect yourself from financial failure. Cannabis will never grow more valuable over time, therefore, you want to have a plan in place for distribution, as soon as the cannabis is harvested and processed. Just as was the case in the black-market days, you never want to hold on to your cannabis for long periods of time.

Do not distribute without agreements in writing! While some oral agreements may be enforceable, it will be extremely costly to litigate. Therefore, you should plan to hire a lawyer beforehand to create fail-proof agreements that will hold up in court, should a distributor not pay you for your product.

Sales – Build your brand, but be realistic

Building your brand is important. And if you don’t produce your own high-quality flower you cannot expect to have a product up to your standards. Your brand will not be successful if you cannot consistently provide consumers with high quality cannabis. Relying on other growers to produce your cannabis for you is risky to your brand. Even if you are a manufacturer, you may not be able to rely on other suppliers to maintain the quality volume you need in order to manufacture your products consistently.

The regulated market in California is new. Therefore you must necessarily account for a great degree of price fluctuations in the market. When creating your budget at the outset, you must account for fluctuations in profit. Knowing when prices are going to be at their lowest can help you avoid having an oversupply of inventory. It can also help you avoid such situations by planning your cultivation/harvest accordingly.

There are both consumer and government influenced market trends that can affect your bottom line. These must be accounted for at the outset.

On the consumer level, you must know what people are buying and how they are consuming. And these factors can change quickly with the introduction of new technology, methods or new devices intended for cannabis consumption. You must stay on top of these trends.

The government regulations can also affect these trends. Products used for cultivation can become banned, i.e. products you once relied on in your cultivation can be found to have contaminants known to cause test failures, even in “approved products.”

Ultimately, all of these factors can make or break your success, and therefore, must be considered, researched and accounted for prior to beginning your cultivation in the regulated market. Working with a consultant with over 20 years of grow experience, and more importantly, extensive experience in large scale cultivation in the regulated market, can help you achieve the success you desire. Cultivation in the regulated market is costly, but working with a consultant can help you cut costs at the outset, and save you from unexpected expenses in the long run.

The CalCannabis Appellations Project Is About to Spark a New Chapter in Place-Based Branding

By Amy Steinfeld, Jack Ucciferri

1 Comment

Connoisseurs know that pairing a fine cut of steak with a Napa Valley cabernet sauvignon is a sure winner. But how many are aware that pairing strawberry cheesecake with a certified Santa Cruz Blue Dream cannabis strain creates an equally delicate palatal synergy? Thanks to the California Department of Food and Agriculture’s CalCannabis Appellations Project (“CAP”), premium cannabis regions will soon have the potential to capitalize on such newfound awareness among discerning consumers.

For decades, cannabis connoisseurs have been willing to pay a premium for flower said to have been grown in certain regions or with certain techniques, but because of cannabis’ legal status, supply chains have been opaque. As a result, cultivators of distinct cannabis strains struggled to capture the full market potential of their products. That has begun to shift with implementation of California’s Cannabis Track-and-Trace System. The costs associated with implementation of the METRC¹ system have been bemoaned by many in the industry, but there is also tremendous potential value in having the most transparent supply chain in the world. The CalCannabis Appellations Project is the vehicle through which brands will be able to harness that value.

The underlying premise behind the CalCannabis Appellations Project is that the distinctive qualities of a cannabis product are often attributable to where and how the plant is grown. Through this project, CalCannabis is developing a statewide appellations system² that will allow qualifying licensed cultivators to effectively communicate information about their cannabis crops (i.e., the standards, practices and/or varietals used) through labels, advertisements and other marketing techniques. It will also prevent disingenuous cannabis cultivators from making inaccurate claims about where and how a product is grown, which protects the integrity and value of the appellation.

What is an appellation?

In general terms, an appellation is an identifying name, title or label that can be legally defined and protected. Appellations are most commonly used in the wine industry to geographically identify the origin of grapes in a particular bottle. This place-based identification system comes from an understanding that certain regions have unique environmental and growing characteristics, which result in a product that cannot be produced from other regions even when the same varietals are used. Famous wine appellations or American Viticultural Areas (AVAs) in California include the Napa Valley and Santa Ynez AVAs, and sub-AVAs such as the Russian River Valley AVA, located within the larger Sonoma County AVA.

Recognizing there are also growing regions that produce uniquely distinctive cannabis, CalCannabis is developing a process for:

Establishing an appellation (i.e., identifying regions that produce distinctive cannabis and defining standards, practices and/or varietals that must be used in those regions to qualify for an appellation); and
Qualifying to use a particular appellation once they are established (i.e., determining the cannabis cultivators that can legally label or market themselves as belonging to a particular appellation).

While the state has not released program details, it’s likely that cultivators will have to demonstrate their outdoor-grown cannabis is distinctly unique.³ CalCannabis has until Jan. 21, 2021,⁴ to establish these processes, but a draft is expected to be released by early January 2020.⁵ This is an opportunity for cultivators to organize and participate in the process to define and create unique local appellations.

What are the benefits of an appellations system?

Appellations benefit both cannabis cultivators and consumers. It allows small farmers to capture the value that consumers place on unique and local cannabis products. Allowing for product differentiation through an appellations system will prevent cannabis from becoming a commodity—a situation that could result in indistinguishable products and a single market price for cannabis regardless of how or where it is grown. Thus, an appellations system protects not only local economies and farming communities, but also consumers that care about the origin and growing practices of their cannabis.

A criticism of appellations, particularly in the wine industry, is that they can disincentivize innovation and industry growth when strict growing practices and standards are required to be a part of an appellation. This will be an important consideration as CalCannabis establishes its appellations system.

County of Origin

In addition to setting up an appellations system, the CalCannabis Appellations Project will expand upon current county of origin regulations. Unlike an appellation designation, the county of origin designation is designed to be much more inclusive—it can currently be used on any cannabis product as long as 100% of the cannabis is grown within the designated county.⁶ Whereas an appellation will communicate information about the quality of a cannabis product and how it was produced, a county of origin designation is more like a “Made In” label. For example, a county of origin designation can be applied to indoor cannabis whereas an appellation will likely only include sun-grown cannabis.

There is also a desire to allow city of origin designations in addition to county of origin designations, which would enable products grown wholly within the political boundaries of a city to further differentiate themselves.⁷ As the legal cannabis landscape changes nationwide, it may also be important to have a statewide appellation allowing products to be marketed as “Grown in California.”

What should cannabis cultivation regions be doing now?

After CalCannabis releases a draft process for establishing an appellation, the next steps will be clarified. However, not everyone is waiting. For instance, growers in Mendocino County have already started to organize.⁸ The Mendocino Appellations Project divided the county into 11 unique subregions based on regional growing conditions and practices that could potentially be turned into appellations in the future. The goal of the appellations outlined by the Mendocino Appellations Project is to protect cannabis products coming out of Mendocino County and preserve the region’s growing heritage.

A group in Sonoma County is also discussing the establishment of appellations with the hope that it will help differentiate their cannabis and draw attention to the unique microclimate and soil structure in parts of Sonoma County.⁹ The groups involved in these discussions also believe it will allow cultivators to develop strict growing standards and to protect certain strains, while creating new jobs and encouraging agritourism. Appellations will become increasingly important as sophisticated consumers begin to select quality cannabis that aligns with their preferences.

Taking the Guesswork out of Horticultural Lighting

By Leora Radetsky

1 Comment

With 33 states and the District of Columbia having passed laws legalizing marijuana in some form, cannabis cultivation is quickly becoming a booming new business across much of the US. From an energy standpoint, unfortunately, it’s not easy being “green”.

New Frontier Data’s 2018 Cannabis Energy Report found that legal cannabis cultivation in the US consumes approximately 1.1 million megawatt hours of electricity annually – enough to power 92,500 homes or a community the size of Newark, NJ, and accounts for carbon emissions equivalent to that of 92,600 cars. And that consumption is forecasted to increase 162 percent from 2017 to 2022. The report recommended that the industry “evaluate energy-efficient and renewable energy technologies” to nip this challenge in the bud.

Growers seeking to reduce their electricity usage through more efficient lighting face a confusing landscape of options, however. It can be difficult to know what will save electricity and work well for their operations. Technology is advancing quickly and questions abound, from how long a fixture will last and whether a manufacturer’s claims about efficacy are accurate to the effectiveness of various wavelengths for growing a particular plant.

Here’s the good news: there are reliable, third-party lighting and safety standards to help indoor growers make the leap from old-school lighting to state-of-the-art light-emitting diodes (LEDs) that use a fraction of the electricity and are increasingly effective for growing crops from cannabis to tomatoes. Here’s a closer look:

Most lighting fixtures in the North American market go through rigorous inspection by certified third-party testing labs. The first part of the check is for safety – an official UL safety standard tailored for the unique challenges of the greenhouse environment was recently released (UL 8800, the Standard for Horticultural Lighting Equipment and Systems). This standard and similar safety certifications at other major labs address wiring, environmental conditions, ingress protection and worker safety related to prolonged photobiological exposure to the eyes and skin. Growers should always ask a fixture manufacturer about safety certification specifically targeted for horticultural environments.

Next on the standards checklist for horticultural fixtures is performance testing. This often happens at the same labs that do safety testing, but is designed to verify efficacy, output, spectrum and other important performance variables. Commercial labs are certified for specific standards, so that a test on a fixture is repeatable at any other lab certified to the same standard. This performance testing results in a report summarizing items like photosynthetic photon flux (PPF), input power (watts), photosynthetic flux efficacy (PPE, measured in μmol/J or micromoles of photosynthetic photons per joule of electrical input power), and spectral content (flux per nanometer (nm) between 400 and 700 nm).

Then, there are flux maintenance standards (such as IES LM-80 and IES TM-21) that help make sure the photosynthetic light output of LED products degrades at an acceptable rate to make a grower’s investment worthwhile. The testing and calculation methods that go into these standards were painstakingly developed through a consensus of knowledgeable lighting stakeholders. A key difference between general lighting and plant lighting, however, is how flux maintenance is measured and benchmarked – the bar is significantly higher for plants compared to people since their metabolism and growth are dependent on the light spectrum and amount.

A plant in flowering under an LED fixture

What’s described above just scratches the surface of the detailed testing used to determine and communicate performance features for commercial horticultural lighting fixtures. There’s a lot of important information to know, but it takes an informed reader to analyze this information and use it to select appropriate horticultural lighting. Our organization, the DesignLights Consortium (DLC), strives to make the vetting process easier for everyone, freeing up growers to focus on their core business.

In the early days of LED lighting, electric utilities had to compare these different lighting factors and reports to inform their energy efficiency rebate/incentive programs. The DLC was founded to fill this need, serving as a central clearinghouse for setting energy efficiency and other product performance minimum standards, and to evaluate products against those standards. Then and now, lighting products that pass review qualify for an online qualified products list (QPL) that utilities use to quickly and accurately incentivize high-performing products.

With its new minimum performance standards for horticultural light fixtures, the DLC seeks to accelerate the adoption of new energy-saving LED fixtures in controlled agriculture environments. To be on the new DLC Horticultural QPL, an LED fixture must be at least 10 percent more efficacious than the best non-LED alternative – a 1,000-watt double-ended high-pressure sodium (HPS) fixture. It also must have a Q90 of 36,000 hours (the number of hours before the photon flux output depreciates to 90 percent), and its driver and fan (if included) must have a rated life of at least 50,000 hours.

Most importantly, every product is listed online in a searchable, filterable database to help growers and facility designers quickly narrow their options. For example, in a retrofit, a grower might know what PPF is needed from each fixture but might also need to stay within a power budget to avoid rewiring circuits. The DLC’s Horticultural QPL can be filtered to quickly find and compare conforming products.

When a new technology is introduced, there is always uncertainty about how to optimally apply it. The horticultural world is no different. We look forward to research supporting additional predictive metrics that allow us to take advantage of the full benefits of high-performance LED and controls technologies. In the meantime, the established standards described here allow for energy efficient and safe cultivation facilities where growers can confidently produce more with less.
