Building or Converting to a Greenhouse? Four Considerations for Commercial Growers

By Taylor Engert

Successful cannabis cultivation practices leverage commercial agricultural industry practices for the most efficient and cost-effective production of the crop. Since the 1990s, the cannabis industry has cultivated primarily in indoor warehouses and outdoor farms, however the industry is experiencing a significant shift toward greenhouses.

Shelly Peterson, vice president of light product solutions at urban-gro, joined a recent panel of industry experts including Shivawn Brady, chief executive officer and founder of Seva Crop Consulting, and Karl Keich, executive director at Canna Consulting Group, at the Marijuana Business Conference in Orlando, Florida, to discuss how to transition from an indoor or outdoor grow to a greenhouse facility.

What are the considerations when deciding between a warehouse and greenhouse? The panel shares four factors around the costs and operational challenges, and the benefits of a greenhouse.

Maximize Efficiency in Every Process

Why are cannabis cultivators looking toward greenhouses? Peterson says it is all about efficiency. “In a warehouse, electricity costs can run up to 50 percent of the total cost of goods sold, which is a tremendous amount that can be decreased by switching to a greenhouse,” says Peterson. “In a greenhouse, you can add supplemental lighting to augment what the plant is receiving from the sun.”

For cultivators, Peterson noted that it is critical to ensure growers have experienced vendors and advisors on the team to help maximize the efficiency of the greenhouse. “As the cost of this product comes down, the efficient growers will be the ones in it for the long haul,” added Peterson.

Construction vs. Operating Costs

The panel identified upfront cost as one of the biggest challenges faced when building out a greenhouse. “The cost of retrofitting a warehouse and building a greenhouse are similar, but where you will save is in the operational costs,” says Peterson. “Lighting can be up to one third of your total cost in indoor facilities, when you switch to a greenhouse that cost can be reduced by 50 to 70 percent.”

Brady acknowledged that some traditional greenhouses have challenges in controlling the environment, but automated greenhouses offer retractable roofs and siding. “If you have the resources to invest in your greenhouse system upfront, that is generally a better way to save money in the long run,” says Brady. “Managing pests in greenhouses can also become very challenging if you don’t have the proper climate regulations.”

Lighting for Your Greenhouse

One of the greatest benefits of growing in a greenhouse is the ability to source natural light. But what about the required light levels? Peterson pointed out that light levels change throughout the year and the plants have different light needs in different stage. Supplement with a lighting system that can read the natural light levels received over any given period of time and be adjusted accordingly. “Greenhouse facilities also need to be outfitted to meet the needs of the cannabis plant, which differ in some ways from other agricultural crops,” says Peterson.

Peterson explained that every light is designed with a different purpose in mind. “There are different lights for indoor warehouse facilities where the lighting system provides 100 percent of the available light for cannabis growth versus supplemental lighting for greenhouses,” Peterson adds. “The key is to measure how much light is actually delivered by the sun on a daily basis, which changes throughout the year; at urban-gro, we supplement the facility with light fixtures that will not create shadowing during hours of sunlight and adjust to reach the optimal collective light levels.”

With LED lighting a hot button topic, Peterson explained that the most important consideration for any light fixture, whether LED or HPS, is it’s efficiency capacity. “It all depends on the budget and payback period and a lot of numbers need to be crunched,” says Peterson. “Yield is directly correlated to light; planning properly, sealing your environment, making sure you have the right target DLI, and buying good light meters, are all key.”

Make a Positive Impact and Quality Product

Brady noted that industry leaders are conscious of positive impact towards human health and environmental stewardship when moving to a greenhouse. Cultivators may find the process challenging initially, however the facilities are quite easy to operate and manage, and allow stress-free cultivation of commercial-scale crops.

Keich added that the cannabis industry is becoming more like commercial agriculture. By utilizing the correct technologies and regulators, greenhouse cultivation makes the crop smell, taste and look that much better. “Let’s use natural sunlight to minimize costs and be environmentally friendly to produce a superior product,” says Keich.

Peterson wrapped up by stressing that cultivators should evaluate the greenhouse environment and lighting to improve their bottom line. “Look at the most efficient way to lower your cost of goods sold. Lighting is a very big component to that,” she continued. “Make sure you evaluate the efficiency of the fixture and ask the questions: Why are we targeting this light level? Is the color spectrum correct? Are you measuring in micromoles per watt? These are all different questions, however figure out how much light is coming out of the fixture and verify it for yourself, and you will be successful,” says Peterson.

Solutions for Cannabis Cultivation: Integrated Pest Management

By Aaron G. Biros

3 Comments

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.

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.

prosodic — Procidic works on contact and with residual action.

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.

The Great LED Debate

By Aaron G. Biros

5 Comments

The preferred choice for indoor cannabis growing has long been high-pressure sodium (HPS) 1000-watt light bulbs during flowering. Light-emitting diodes (LED) are quickly changing the indoor farming landscape with innovative technologies and promising energy savings. Many think the technology still needs time to develop. There are certainly many pros and cons to switching an indoor cultivation facility from HPS to LED lighting systems.

Steve Kruss, president of Light-Waves Electronics, Inc., gave a comprehensive analysis of the advantages and disadvantages of various light sources at the CannaGrow Conference and Expo. “The first adopters [of LED light technology] more than two years ago did not get the results they wanted, so many growers gave them a bad rap very early on,” says Kruss. His discussion delved into the pros and cons of both LED and HPS lights in growing cannabis.

It is important to highlight the weaknesses in many common HPS systems and the possible solutions that LED technology could offer. According to Kruss, HPS lights do not match the light spectrum’s photosynthesis curve that plants need to absorb energy. HPS lights give off a tremendous amount of heat that requires more energy to cool a facility down with an HVAC system, increasing energy costs for growers. Since LED’s use 50% less wattage, they produce approximately 50% less heat, significantly reducing cooling costs. HPS light bulbs need to be replaced multiple times per year. Quality LED fixtures can last more than 50,000 hours, or roughly eleven years. “The reality is HPS is putting a lot of light out but that energy is wasted because so much of it is in a light spectrum that plants do not absorb,” says Kruss. Perhaps most important is the lack of ability to vary the light spectrum; any light that HPS bulbs produce that the plant does not absorb is essentially wasted energy.

LED light bulbs provide a solution to the wasted light in HPS by targeting the particular spectrum that plants need for photosynthesis. By targeting the photosynthetically active radiation (PAR), roughly 400-700nm, LEDs can effectively mimic the sun’s ability to produce the wavelength of light specifically needed in a certain stage of cultivation. The absorption spectra and action spectra are wavelengths of light preferable for harvest as well as plant growth and metabolism, respectively. LED manufacturers and growers commonly try to harness the Emerson Effect, which uses red (670nm) and far red (700nm) to increase the rate of photosynthesis.

The benefits of LED lights in growing cannabis are numerous. The primary benefit is that it provides light at the specific wavelengths chosen to match the specific needs of plants. When finely tuned, LEDs can influence the growth process by slowing down vegetative plant growth and inducing flowering when appropriate. LEDs are more energy efficient than their counterparts partially because they give off substantially less heat in the beam itself, reducing cooling costs. Some growers use LEDs together with HPS lights, some use LEDs with natural sunlight in a greenhouse setting and some use strictly LEDs for the entire growth cycle. Each cultivation operation has its own budgetary restraints and structural limitations, but energy efficiency is one area that all growers should look to improve. According to Adam Koh, chief cultivation officer of Comprehensive Cannabis Consulting (3C), indoor growers can get away with T5 fluorescent lamps (which do not consume much energy) throughout the vegetative process.

For some, the debate is over and growers recognize the added benefits that LEDs bring to growing cannabis. According to Kruss, LED technology is almost there. “In terms of yields, LED lights are providing around 75% of the weight that HPS produces, but on the vegetative side, the growth is considerably faster which could make up for that weight loss with faster grow cycles and an extra harvest,” says Kruss.

Talltrees — An LED cultivation operation set up by Tall Trees LED Company

Adam Jacques, award-winning grower and founder of Growers’ Guild Gardens, has used LEDs in tandem with sunlight. Him and his team have bred and grown cannabis in indoor, greenhouse and outdoor operations. “I love the huge steps that some LED manufacturers have made in the past year,” says Jacques. “When I utilize them within a greenhouse setting I really like the product it grows.” Jacques’ findings in the field echo Kruss’ statements that LED lights have made considerable progress very recently. “It does take a little dialing in due to the plants’ increased feeding regiment, but it is a small price to pay for all of the benefits we see,” adds Jacques. His success with the new technology is representative of a larger trend; more and more growers are beginning to implement LEDs in some form.

Some claim the yield is less from LED lights during flowering.

Maxx Wiley and Robert Manes, co-founders of Tall Trees LED Company based in Arizona, believe their technology is on par with the yields other growers are getting with different light sources. “We conducted heads-up tests with our 500-watt LEDs versus other 1000-watt HPS bulbs and have seen very impressive results,” says Wiley. “The plants under our lights were consistently getting more weight and more flowers; the flowers appeared smaller but were actually denser and heavier in reality.” Wiley’s company makes commercial LED luminaires that are IP 65 waterproof rated and he claims they never had any issues with failures. The technology uses no moving parts to cool the lights, just metal clad circuit boards, heat sinks and conductive thermal-bonding materials. “We have had customers run potency analyses and have found tremendous variation in plants grown with HPS,” says Wiley. “We see more compound production and more consistency crop-to-crop with our LED technology.” There are currently a handful of manufacturers bringing innovative designs to market.

GS Thermal Solutions, based in Connecticut, manufactures 1000-watt LED fixtures that are liquid-cooled. The company makes lights that are fully adjustable, so growers can dial in each spectrum of light intensity independently and tailor to specific strains as well as stages of growth. According to Rick Rhyins, vice president of sales at GS Thermal Solutions, the liquid cooling technology allows for a much longer lifetime of the LED and a much more efficient energy consumption. “Our technology addresses the shortcomings and previous problems with early generation LED models,” says Rhyins. Coupled with facility automation, GS Thermal Solutions uses a central control system to monitor cooling, light intensity and spectra, nutrient monitoring and feed control.

Yet some are still skeptical of the LED lighting in today’s market and feel the technology is not there yet. Nic Easley, chief executive officer of Comprehensive Cannabis Consulting (3C), has brought over sixty cultivation operations to market and is hesitant to endorse the technology at this point. “I will never be an early adopter when it comes to new lighting technology and I feel we are at least a year out from seeing consistently efficient LED lighting,” says Easley. “There are still a lot of false claims out there and I want to wait until I see repeatable results on a small scale before I feel comfortable endorsing LED lights for cannabis cultivation.” While companies will continue to innovate lighting solutions for indoor cultivation, in many cases (but not all) it seems using the sun to grow cannabis would be more energy efficient.

CannaGrow: Education on the Science of Cultivation

By Aaron G. Biros

No Comments

The CannaGrow Conference & Expo, held in San Diego on May 7^thand 8^th, educated attendees on the science of cannabis cultivation. The conference brought subject matter experts from around the country to discuss cannabis breeding and genetics, soil science and cultivation facility design.

Discussions at the conference delved deep into the science behind growing while providing some expert advice. Drew Plebani, chief executive officer of Commercial Cultivator, Inc., gave a comprehensive review of soil ecology and how understanding soil fertility is crucial to successfully growing consistent cannabis. “Soil fertility is measured by laboratories in terms of soil minerals, plant-available nutrients, percent of organic materials, pH levels and most importantly the balance of the soil’s chemical makeup,” says Plebani. “There is no silver bullet in soil ecology; increasing your soil fertility comes down to understanding the composition of soil with analytical testing.” Plebani went on to add that soil systems for cannabis need to be slightly fungal-dominant in developing an endomycorrhizal system, which is optimal for cannabis plant growth.

Plebani notes that growth and viability are reliant on maximum root mass.

Tom Lauerman, colloquially known as Farmer Tom and founder of Farmer Tom Organics, kicked off the conference with an introduction to cultivation techniques. Lauerman also delved into his experience working with federal agencies in conducting the first ever health hazard evaluation (HHE) for cannabis with the National Institute for Occupational Safety and Health (NIOSH). Through the HHE program, NIOSH responds to requests for evaluations of workplace health hazards, which are then enforced by the Occupational Safety & Health Administration (OSHA). Lauerman worked with those federal agencies, allowing them to tour his cultivation facilities to perform an HHE for cannabis processing worker safety. “I was honored to introduce those federal agencies to cannabis and I think this is a great step toward normalizing cannabis by getting the federal government involved on the ground level,” says Lauerman. Through the presentation, Lauerman emphasized the importance of working with NIOSH and OSHA to show federal agencies how the cannabis production industry emerged from the black market, branding itself with a sense of legitimacy.

Attendees flocked to Jacques and his team after the presentation to meet them.

Adam Jacques, award-winning cultivator and owner of Grower’s Guild Gardens, discussed his success in breeding CBD-dominant strains and producing customized whole-plant extractions for specific patients’ needs. “I find higher percentages of CBD in plants harvested slightly earlier than you would for a high-THC strain,” says Jacques. “Using closed-loop carbon dioxide extraction equipment, we can use multiple strains to homogenize an oil dialed in for each patient’s specific needs.” As a huge proponent of the Entourage Effect, Jacques stressed the importance of full plant extraction using fractionation with carbon dioxide. He also stressed the importance of analytical testing at every step during processing.

Hildenbrand discussing some of the lesser-known terpenoids yet to be studied.

Zacariah Hildenbrand, Ph.D., chief scientific officer at C4 Laboratories, provided the 30,000-foot view of the science behind compounds in cannabis, their interactions and his research. With the help of their DEA license, he started the C4 Cannabinomics Collaborative, where they are working with Dr. Kevin Schug at the University of Texas-Arlington to screen various cannabis strains to discover new molecules and characterize their structure. “Secondarily, we are using gene expression profiles and analysis to understand the human physiological response and the mechanism through which they elicit that response,” says Hildenbrand. “As this research evolves, we should look to epigenetics and understanding how genes are expressed.” His collaborative effort uses Shimadzu’s Vacuum Ultraviolet Spectroscopy (VUV), and they use the only VUV instrument in an academic laboratory in the United States. “Pharmaceuticals are supposed to be a targeted therapy and that is where we need to go with cannabis,” says Hildenbrand. Him and his team at C4 Laboratories want to work on the discovery of new terpenes and analyze their potential benefits, which could be significant research for cannabis medicine.

Other important topics at the conference included facility design and optimization regarding efficient technologies such as LED lighting and integrated pest management.

BudGloves Makes Handling Cannabis Safer

By Aaron G. Biros

2 Comments

Kush Bottles, a packaging provider specific to the cannabis industry, recently launched the product BudGloves aimed at reducing the amount of human contact to cannabis products. The company is known for their child-resistant, regulatory compliant packaging.

The product BudGloves is the first glove of its kind engineered specifically for cannabis. The nitrile gloves do not contain any powder and are designed to prevent any transfer of resin, latex or powder to the cannabis. They are also slightly thicker than most other gloves to avoid getting caught or tearing, extending their life to withstand the typical shift of a trimmer or processor.

Nick Kovacevich, chief executive officer of Kush Bottles, wants to see a standard for preventing human contact with cannabis products to reduce the risk of contamination or loss in quality. Whether it is during cultivation, trimming, inspection, processing, transferring cannabis to instrumentation or even at the point of sale, it is important to minimize human contact to the cannabis.

“In California, we see bud tenders in dispensaries actually reach in a jar and grab cannabis to show the patient without gloves, which is a terrible standard operating procedure,” adds Kovacevich. “I would want all bud tenders to handle cannabis with gloves on.”

Particularly when handling food-grade products, most health code regulations require the use of gloves like these. According to Kovacevich, oils and extracts can be at a greater risk of contamination. “It is imperative that concentrates and extracts, especially those with activated THC, are handled with gloves to prevent any outside materials or contaminants from sticking to them,” says Kovacevich. The gloves are manufactured to meet stringent quality standards. To promote safety and quality of cannabis, reducing human contact with the product should be an important part of any company’s employee manual.

The Importance of Traceability

By Aaron G. Biros

No Comments

With the news of Pennsylvania’s medical cannabis legalization measure passing, lawmakers are clamoring for strict regulatory oversight in the form of traceability to prevent diversion and misuse. State Senator Daylin Leach (D- Montgomery/Delaware) introduced the bill and believes it will have the most intensive protections for safety in the country. “Our goal was to create a system that helps as many patients as possible, as soon as possible and as safely as possible,” says Steve Hoenstine, spokesperson for State Senator Leach. “The seed-to-sale tracking system and the bill’s other protections do just that.”

At the recent Cannabis Labs Conference, Cody Stiffler, vice president of government affairs at BioTrackTHC, discussed why traceability is so important. Stiffler previously served as the chief executive officer of the American Medical Management Association, where he fought the Florida prescription drug abuse epidemic. “We originally started tracking prescription medications and methamphetamine precursors to combat the prescription drug abuse and meth epidemic in Florida,” says Stiffler. He focused on providing accountability and traceability, making sure every prescription was legitimate and keeping drugs off the black market. Implementing tracking protocols allowed for the accountability of pharmacists, physicians and patients.

The primary goals of a traceability system, according to Stiffler, are to prevent diversion and promote public safety. “We want to advance the cannabis industry with respect to traceability and regulatory compliance by integrating laboratory testing with traceability,” says Stiffler. “Our software helps get safe products to patients and consumers in a responsible manner.”

Stiffler’s role at BioTrackTHC is to provide industry insights to states looking to legalize cannabis and support them with identifying the best practices that meet requirements in their state. Traceability is commonly defined as the ability to verify history, location and application of a product from source to distribution. BioTrackTHC’s tracking software covers everything from seed to sale, involving regulatory bodies in oversight. In the beginning of cultivation, each plant is assigned a bar code or sixteen-digit identifier. According to Stiffler, Colorado’s system uses radio-frequency identification (RFID) tags while Washington’s system gives the business a choice because the software can work with any type of identifier, whether it is a barcode, QR code or RFID tag. “Our system generates those numbers and prevents diversion with a closed loop system,” says Stiffler.

Washington, Illinois, New York, New Mexico and Hawaii are the five states that use BioTrackTHC’s software. “If the state wants to see the chain-of-custody, they can go back in the system and see every touch point and the full life cycle of the product in real time,” says Stiffler. “Our system also incorporates lab testing to ensure no product reaches shelves unless test values are associated with it.”

For many states, problems lie not in diversion, but inversion, where black market growers bring their products into the legal market. “A lot of people growing black market product are inverting it into the regulated market,” notes Stiffler. This kind of black market activity can flood the legal market with un-tested cannabis.

Product recalls are examples of when traceability software can be very useful. Pesticides, microbiological contaminants, heavy metals and other contaminants are at issue. Stiffler invokes an example from a company in Washington making THC-infused drinks. “Because of an issue in the manufacturing process, the bottles were exploding in refrigerators and on shelves,” says Stiffler. “Because the product’s lineage was completely tracked, we could isolate all of the products in that specific batch from that specific manufacturer and then forward trace to every retailer that had it in inventory,” he adds. “Whenever someone who did not get the recall notice would attempt to scan that barcode at point of sale, a message appeared noting its recall status and that it is not for sale.” The software’s financial data analytics can provide real time visibility for profit margins or losses resulting from recalls.

According to Stiffler, these kinds of protections in place give law enforcement and government agencies piece of mind that they are helping to prevent diversion and promote public safety. Traceability software is one of the very important safeguards protecting food safety and product safety.

A New Tool to Make Cannabis Evaluation Easy

By Matthew Huron

3 Comments

All cannabis is not created equal.

Just as industry experts have developed a set of tools to assess artisan experiences with wine, craft beer and diamonds, our team of cannabis cultivators at Good Chemistry Nurseries- who hold decades of experience backed by extensive education in horticulture and botany- have developed a new consumer guide to evaluate the essential aspects of cannabis called STATS (Sight, Touch, Aroma, Taste, Sensation). We hope the newly developed guide will begin an industry-wide dialogue about consumer education and provide fundamental knowledge on how to evaluate the quality of a cannabis flower.

STATS was created in response to our customers’ growing desire to differentiate between high quality and low quality flower. Two years ago, a consumer may have walked into a dispensary, and may have been thrilled just to be able to buy legal and safe cannabis. Fast forward two years, and now they’re asking, “How do I recognize quality cannabis?” By introducing STATS as a consumer awareness campaign, we are hoping to meet the needs of consumers to understand the complexities of the cannabis flower, as well as opening up the industry to a more conservative market that might be overwhelmed and intimidated by the cannabis culture.

STATS, which is available at no cost at statsguide.org and at Good Chemistry dispensary locations, is designed as an interactive booklet that breaks down the complexities and characteristics of quality cannabis through the five main categories; sight, touch, aroma, taste and sensation. The short, easy-to-read tool also comes with a concise glossary, which includes definitions of cannabis-related words, and expressions that might not be palpable to a novice consumer. Here is an overview of the STATS tool to evaluate quality cannabis:

Sight: Seeing the flower can sometimes be the only evaluation option before purchase. It is important to know the visual cues for remarkable cannabis. STATS help consumers evaluate qualities including: trichome content, color, structure, size and trim.

Touch: Touching the flower can help with evaluating the cure, or the controlled drying process used to achieve proper moisture content post-harvest. STATS define how the bud should feel.

Aroma: Distinctions can be made between high and poor quality cannabis aroma. Because each flower strain can have a unique scent, STATS reviews what scents should be expected, and what smells can denote poor quality.

Taste: Different flowers strains will have unique flavor profiles. Similar to wine tasting, experience is necessary, STATS helps consumers learn to distinguish between different flavors among the flower strains.

goodchemistryteam — The development team of STATS

Sensation: The first sensation that comes from cannabis is the sensation of lift, or of being high. Varying experience levels may affect how people feel with each strain and the amount of time people feel lifted. We have identified the key categories of sensations that come from different strains including amplify, relax, relieve, and sleep.

Now, there is an easy and free tool to provide novice and aficionado cannabis users new insight and understanding into the purchase they’re about to make. Good Chemistry Nurseries developed STATS in conjunction with our Colorado-based master cultivators Duncan Cameron, Scott Toland, Heath Byington and Stephen Spinosa. Our development team came to this idea with a strong desire to address consumers’ interest in learning more about how to assess high quality cannabis.

Following a Cannabis Sample Through the Lab: 9 Important Steps

By Tegan Adams

No Comments

Anytime a cannabis sample enters a laboratory, the sample is received, handled, weighed, identified and traced throughout the testing and disposal process. Laboratories working with cannabis must have quality systems in place to ensure every action taken to test the cannabis sample is documented and in compliance with good manufacturing practices. Eurofins-Experchem’s sample receipt and handling SOPs includes the following key elements.

Purpose: The purpose of the SOP is outlined to make sure it’s outcome is understood
Scope: The Scope of the SOP explains what events the SOP is intended to avoid and which events the SOP is intended to encourage
Responsibilities: All positions that the SOP affects are outlined
Initial Receipt of the Sample: Samples are submitted to Eurofins Experchem Laboratories with a Sample Information Form. In Canada, cannabis is regulated as a controlled substance. Controlled substances come with a special shipping document and must be weighed upon receipt to the lab to make sure the weight is the same as the client has indicated. Cannabis samples received are inspected to ensure no tampering or damage has occurred to the sample before it is tested. Any temperature and/or storage requirements are noted and followed. If any conditions are not understood the client is contacted for clarification immediately. Pending the sample’s conditions are met, the sample is placed into the laboratory.
Procedure: Eurofins Experchem uses its own sample tracking software to track a sample across the lab. A unique project number and date of entry is given to the sample. Client name, product name, condition of sample, test(s) performed, ID or lot number and size of samples are all recorded. A sticker is attached to the sample to clarify.
Rush Samples: Rush samples are stamped “RUSH” in red and are placed in a priority sequence. The sample is placed in the safe until required for testing. If the product is not cannabis, the sample is placed on a shelf corresponding with the actual day of the month it was received and entered into sample tracking. If the sample requires cold temperatures it is placed in a refrigerated area and monitored in a similar way.
Discrepancies: Any discrepancies in information found on the sample that may differentiate from what the client requests will be communicated to the client upon finding.
Controlled Documents: Stickers, original lab specification sheets, sample submission forms, and SOP training evaluation questionnaires.
Results: As soon as testing is completed, lab results are approved by quality assurance reviewers. A Certificate of Analysis (COA) is electronically and automatically sent through the sample tracking system to the client’s email.

Strain-Specific Labeling Edibles

By Dr. Emily Earlenbaugh, PhD.

No Comments

As the marketplace for cannabis products continues to evolve, we are seeing more and more strain-specific edible products hitting the shelves. Still, the majority of products remain strain-ambiguous, simply mentioning that the products contain cannabis and perhaps whether they are indica or sativa blends. While there are compelling reasons to go strain-specific, there are also serious challenges to doing it well.

The most compelling argument for strain-specific edibles is that your patients are more likely to get what they want (and thus more likely to come back for more). Many strain sensitive patients avoid almost all edibles because of a few bad experiences. Without knowing what strain you are consuming, you are left to gamble with your experience. Rather than take the risk, many patients choose to make edibles at home.

When talking to patients, I hear countless stories of bad experiences, along with the desire for more strain-specific edibles. Of course, creating strain-specific products is harder than it sounds. For one thing, it is difficult to source a consistent supply of large amounts of a single strain. This requires either an incredibly well run cultivation operation in-house, or strong, stable relationships with growers that are willing to grow a particular strain consistently.

In addition, labeling becomes more complex when you are strain-specific. Instead of one product, with one package and one label, you need to have individual labels for each strain. If you are using multiple strains, you need multiple labels. For small edibles manufacturers, things can get complicated. They usually need to source cannabis strains from the local market and may not be able to get a lot of consistency. This means plenty of small batches of single strains, rather than a consistent supply of a few set strains, and requires smaller batches of packaging, raising the cost of your inputs. So for many, the solution is to make one label and shift the strains depending on what’s in stock without notifying the consumer. Another method is to blend whatever strains you can find into one type of mixed strain product. While this offers an easy method for producers, it can have negative effects on the patient.

Those continually shifting blends of hybrid, indica or sativa edible products typically contain cannabis trim from many different strains. As we know, strains produce a large variety of effects, from sedative to energizing, relaxing to panic inducing. Mixing many carefully designed strains together can create all kinds of strange effects. It can be akin to mixing medications; it is hard to say what the result of the mix of chemicals will be. This can leave strain-sensitive patients feeling like each edible experience is a roll of the dice, wondering, “Will this help me or hurt me?” A number of patients have told me they gave up on edibles all together.

For those looking to use strain-specific labeling, but feeling held back by issues with sourcing and packaging consistency, try making one product package (that is strain ambiguous) with space for a strain specific sticker. Printing stickers on demand will cost less, then you can label the strains you currently have access to. Giving your patients access to strain information allows them to make an informed choice about what they are taking. Consumer education can draw in a customer base that is already primed to like your product and increases the chances that they will ultimately become satisfied, repeat customers.
