Controlled environment agriculture (CEA) is a hot area of investment right now for the USDA, holding the promise of improved efficiencies and productivity for indoor growing operations. The cannabis industry, long accustomed to indoor growing has emerged as a spearhead in CEA innovation.
The Resource Innovation Institute has been supporting cannabis enterprises as a non-profit entity since 2016, providing a benchmarking platform called Power Score to help cannabis cultivators be more efficient with resources in their growing practices. Recently, RII submitted a proposal to the USDA to bring best practices from the cannabis industry to other CEA crop producers. They have also recently been responding to the Cannabis Administration and Opportunity Act, providing comments to frame an energy and environmental policy framework for future federal regulation.
We interviewed Derek Smith, executive director of Resource Innovation Institute (RII). Derek engages RII’s advisory bodies, including the Strategic Advisory Council and Technical Advisory Council Leadership Committees and develops global partnerships and oversees the organization’s policy work. Prior to RII, Derek was CEO of Clean Energy Works and policy advisor to the City of Portland Bureau of Planning and Sustainability.
Aaron Green: What are RII’s plans for the USDA? I understand you’ve also been working on the CAOA recently?
Derek Smith: We’ve been working in cannabis for five years, publishing best practices and capturing data to inform governments and utilities on how much energy is being used. Our mission is to help producers become more efficient in their use of resources. In addition to informing policies that support producers, we also engage utilities to help them evaluate efficient technologies, so they can put incentives on them and so they can help buy down the cost for cannabis producers to install more efficient technologies.
We submitted a proposal to the USDA, saying we’ve been doing all that in cannabis. This was under the banner of a Conservation Innovation Grant, which is an innovation funding mechanism from the USDA. They specifically wanted something related to indoor agriculture and energy and water efficiency. So, we essentially said, we’ll give you a three-year project that will basically be the blueprint for the controlled environment agriculture (CEA) industry to transform itself toward a more sustainable production path. This applies to both the urban vertical farms growing leafy greens, as well as the growing greenhouse sector that is producing a range of crops, from tomatoes, to berries, to leafy greens to mushrooms, hemp, etc.
We’re essentially taking the Power Score benchmarking platform that we’ve been serving cannabis producers with to help them understand how competitive they are relative to the rest of the data set that we have on energy use and on water use and opening that platform so that more producers of other types of crops can use it. It also feeds into their Environment, Social & Governance (ESG) reporting needs.
We’re going to write a series of best practices guidance for CEA producers, covering a number of topics: facility design and construction, lighting, HVAC, irrigation and water reuse, controls and automation. This will all be very similar to what we’ve done in cannabis. These best practices guides are peer reviewed by subject matter experts throughout the supply chain. A lot of the supply chain in cannabis is the same in CEA. So, we’re bringing them all together to give this kind of good guidance to the producer community.
Green: You started with cannabis and created these white papers. Now you’re branching out into the larger CEA space?
Smith: Exactly. The federal government is literally funding us to develop a green building rating system like LEED, or like the Living Building Challenge, but for the CEA industry for indoor agriculture. The cannabis industry can leverage this federal investment and basically ride right alongside of it so that we can create a “LEED for weed” type of certification system.
Derek Smith, Executive Director of Resource Innovation Institute
That’s one of the main features in our comments to the CAOA when they asked, “what else should we be thinking about on any number of topics as it relates to federal cannabis regulations?” We proposed an energy and environment policy framework for federal cannabis regulation. We did that in partnership with a group called the Coalition for Cannabis Policy Education and Regulation (CPEAR). We just held a webinar two weeks ago. Hawthorne Gardening Company was featured on there as well. They’re very supportive of the federal government playing a “carrots rather than sticks” role as it relates to cannabis energy and environmental policy issues.
That’s essentially our platform at the federal level. The stuff that the USDA is funding us to do will come back and benefit the cannabis industry, because we’ll have this broader set of best practices guidance, data, etc. And then we’ll be able to leverage the federal investment into a certification system for the cannabis industry.
Green: The specific comments you made to the CAOA were primarily related to this energy efficiency certification system work you’ve been doing?
Smith: Yes. It’s more resource efficiency – it’s broader than just energy efficiency. Well, it was three things. So, I’ll just unpack this quickly. One, is learn from the states that have already initiated some form of regulation or support on helping producers be more efficient. Massachusetts is one example. They put lighting requirements on the industry that don’t explicitly mandate LEDs, but it comes close to that. California passed an energy code that will take effect on January 1 of 2023, that also has lighting requirements.
Green: Is this applied to all greenhouse growers?
Smith: Yes, at a certain size and level of energy usage. In California, it’s the first market where their Title 24 regulations apply not just to cannabis, but to all horticultural operations. Yes. So that’s what we’re seeing is that cannabis is sort of the tip of the spear for the way governments are thinking about policy for indoor agriculture more broadly. We’re trying to get them to focus more on having the federal government play a supportive role. The states are doing the regulation, the federal government can be more focused on carrots, not sticks, right?
So, back to the list of three things. Number one is learn from the states. Don’t add regulatory stuff, just learn what’s going on, and then decide about how to act. Number two is recognizing the need for data. So, supporting state requirements on energy and water reporting like Massachusetts, Illinois, California – a lot of states have either enacted reporting requirements, so the producers must tell the state how much energy and water they’re using and they’re using the Power Score benchmarking platform, which has a compliance function for free to do that reporting. Then what we’re doing is helping everybody understand what the aggregate data is telling us. We protect the producer’s confidentiality, and we’re building this valuable data set that’ll inform the market about what is the most efficient path going forward.
Then the third thing is focused on carrots, not sticks. For example, support the development of a certification system that recognizes leadership, that’s based on a market driven voluntary action by a producer where they say, “I’ll be transparent with my data, because I’d like to be showcased as a leader and get recognition for the good work I’ve done to create an efficient operation.” Then there’s valuation through the real estate transaction as well because you even have a plaque on your building that says this is certified to this agricultural standard.
That’s all the vision that we’re laying out, and we’re looking for partnerships at the MSO level to join in and be recognized and get in the queue as leaders for the investments they’ve made in efficiency.
Green: Great, thank you Derek. That concludes the interview.
Three years ago, Canada became one of the first countries in the world to legalize and regulate cannabis. We’ve covered various aspects of cannabis regulation since, but now with a few years of data readily available, it’s time to step back and assess: what can we learn from three years of cannabis recalls in the world’s largest legal market?
Labelling Errors are the Leading Cause of Canadian Cannabis Recalls
Our analysis of Health Canada’s data revealed a clear leader: most cannabis recalls since legalization in October 2018 have been due to labelling and packaging errors. In fact, over three quarters of total cannabis recalls were issued for this reason, covering more than 140,000 units of recalled product.
The most common source of labelling and packaging recalls in the cannabis industry (more than half) is inaccurate cannabinoid information. Peace Naturals Project’s recall of Spinach Blue Dream dried cannabis pre-rolls this year is a good example. Not only did the packaging incorrectly read that the product contained CBD, but the THC quantity listed was lower than the actual amount of THC in the product. The recall covered over 13,000 units from a single lot sold over 10 weeks.
In another example, a minor error made a huge impact. British Columbia-based We Grow BC Ltd. experienced this firsthand when it misplaced the decimal points in its cannabinoid content. The recalled products displayed the total THC and CBD values as 20.50 mg/g and 0.06 mg/g, respectively, when the products contained 205.0 mg/g and 0.6 mg/g.
Accurate potency details are not just crucial for compliance. For many customers, potency is a deciding factor when selecting a cannabis product, and this is especially important for medicinal users (including children), people who are sensitive to certain cannabinoids and consumers looking for non-psychoactive effects. In this case, at least six consumer complaints were submitted to Peace Naturals Project, the highest number for any cannabis recall in Canada.
Pathogens are the #2 Cause of Cannabis Recalls in Canada
Pathogens are the second most common cause of recalls in Canada, claiming 18% of total cannabis recall incidents. And while that doesn’t sound like much compared to the recalls caused by labelling errors, it affects the highest volume of product recalled with over 360,000 units affected.
Canadian Cannabis Recalls – Total number of affected units and noted causes
A primary cause of allergens and microbiological contamination of cannabis products is yeast, mold and bacteria found on cannabis flower (chemical contaminants like pesticides can also be a major concern). Companies like Atlas Growers, Natural MedCo and Agro-Greens Natural Products have all learned this lesson through costly recalls.
These allergenic contaminants pose an obvious health risk, often leading to reactions such as wheezing, sneezing and itchy eyes. For people using cannabis for medical conditions and may be more susceptible to illness, pathogens can cause more serious health complications. Moreover, this type of cannabis recall not only drives significant cost since microbiological contamination of flower could easily affect several product batches processed in the same facility and/or trigger downstream recalls, but also affect consumer confidence for established cannabis brands.
Preventive control plan requirements for cannabis manufacturers mandate that holders of a license for processing that produce edible cannabis or cannabis extracts in Canada must identify and analyze the biological, chemical and physical hazards that present a risk of contamination to the cannabis or anything that would be used as an ingredient in the production of the edible cannabis or cannabis extract. Biological hazards can come from a number of sources, including:
Incoming ingredients, including raw materials
Cross-contamination in the processing or storage environment
Employees
Cannabis extract, edible cannabis and ingredient contact surfaces
Air
Water
Insects and rodents
To mitigate risks, addressing root causes with preventative measures and controls is essential. For instance, high humidity levels and honeydew secreted by insects are common causes of mold on cannabis flowers. Measures such as leaving a reasonable distance between plants, using climate-controlled areas to dry flowers, applying antifungal agents and conducting regular tests are necessary to combat such incidents.
Preventative measures and controls can save a business from extremely costly recalls.
Of course, placing all the necessary controls into action is not as simple as it may sound. Multiple facilities and a wide range of products in production mean more complexity for cannabis producers and processors. Any gaps in processing flower, extracts or edibles can result in an uncontrolled safety hazard that may lead to a costly cannabis recall.
These challenges are not just limited to cannabis growers. The food industry has been effectively mitigating the risk of biological hazards for decades with the help of food ERP solutions.
Avoid Recalls Altogether with Advanced ERP Technology
An effective preventative control plan with regular quality checks, internal audits and standardized testing is important to minimize the threats evident from Canada’s recall data. If these measures ever fail, real-time traceability systems play a pivotal role in the event of a cannabis recall by enabling manufacturers to trace back incidents to the exact point of contamination and identify affected products with surgical precision.
Instead of starting from zero, savvy cannabis industry leaders turn to the proven solutions from the food industry and take advantage of data-driven, automated systems that deliver the reliability and safety that the growing industry needs. From automated label generation to integrated lab testing to quality checks to precision traceability and advanced reporting, production and quality control systems are keys to success for the years ahead.
The supply chain for consumer cannabis products is complex, involving cultivation, extraction, manufacturing and packaging. While global best practices exist for Good Agricultural Practices (GAPs) and Good Manufacturing Practices (GMPs), the certifications are not tailored to the cannabis industry.
CSQ has developed tailored standards for the cannabis industry to assist cannabis companies in improving their quality. As a division of ASI, a woman-owned business that’s provided safety solutions to the food industry since the 1940s, the CSQ standards were built in 2020 to meet ISO requirements, GFSI requirements and regulatory cannabis requirements from seed-to-sale. CSQ is the first cannabis certification program to meet the GFSI Benchmarking Requirements with plans to be benchmarked in 2022.
We interviewed Tyler Williams, CTO and founder of CSQ. Tyler founded CSQ after working at ASI – a family-owned food safety company in St. Louis.
Aaron Green: Nice to meet you, Tyler. How did you get involved in the cannabis industry?
Tyler Williams: It’s kind of a long story, but it’s a good story. My mom worked for ASI for 15+ years. That company has been around since the 1940s and is one of the oldest food safety companies in the world. The owners were ready to sell about five or six years ago, and my mom ended up using a small business loan to purchase the company. That’s how I got started in a food safety and dietary supplement space.
About three to four years ago, we started getting inquiries from cannabis companies asking about GMP audits and certification and different things. We started doing certifications to our GMP food processing standard or dietary supplements depending on what they wanted but realized that there were a lot of things that weren’t applicable to cannabis companies or there were extra things needed for cannabis companies. That’s how I started working with cannabis companies to start developing the CSQ certification program and it has just kind of grown over the years.
Tyler Williams, CTO and founder of CSQ
We currently have four standards at the CSQ level. CSQ plans on being benchmarked to GFSI which stands for Global Food Safety Initiative. We plan on going through that process to get the benchmark next year. There are four standards underneath CSQ: one for growing and cultivation; one for extraction; one for food and beverage edibles; and then cannabis dietary supplements. We’re looking to add standards for cosmetics, cannabis contact packaging materials, retail and consumption lounges.
Last year, when we were doing our pilot audits, we realized that the CSQ standard was great for medium to big sizedMSOs because they’re already doing these best practices. It’s easier for them to, you know, implement a few things, and then get certified, whereas for the smaller guys who might be coming from the illicit market, it’s a lot harder – it’s a lot bigger jump from them to go from zero to 100. Last month, we released our unaccredited cGMP, cGMP+, cGAP and cGAP+ standards. The difference between the regular and the plus is that the plus has HACCP (Hazard Analysis Critical Control Point) and then it also includes a recall module where the site must do a mock recall while the auditor is on-site.
CSQ doesn’t perform the audits. We license the use of our standard to accredited certification bodies and then they must get accredited to be able to certify companies under the CSQ name.
Green: Can you tell me a bit about the genesis of CSQ and the structure of the organization?
Williams: We’re a for-profit company. We thought about going the non-profit route but it’s a lot more intricate and a lot more people involved when you go that route. Our parent company is ASI, and we are under the ASI global standards division which is responsible for developing standards. So, CSQ is one of those standards under that brand and that’s kind of the foundation of it. We have two licensed certification bodies right now. ASI has a certification body, and they are one of our licensed CBs and then WQS, who’s based out of North Carolina and has a big presence in South America which is great because we’re starting to get inquiries from companies in South America as well.
Green: How do you go about building industry awareness and acceptance of the standard?
Williams: Building awareness really started with going out to the medium- to large-sized companies and saying, “Will you open your doors and let us come and basically do all these audits for free at your facility just so we can kind of get a baseline across the industry?” So, that started the conversation with industry. The MSOs in the medium- to large-sized companies, are more ready to go through the certification process because they know that federal legalization is around the corner. They know these things are going to have to be in place already so they’re just doing it as preparation. There isn’t much demand for retailers right now like there is in the food and or dietary supplement space. So that’s where the demand is really coming from – wanting to self-regulate in preparation for federal legalization.
Most of our outreach is education-based. We speak at a lot of conferences. We host a lot of webinars and free events and things like that, just to get the word out about CSQ. A lot of people know what GMPs are, or know that they should be following GMPs, but they don’t necessarily know how to get from point A to point B. Our job is to educate them that it’s not as hard as they think it is and it’s not as expensive as they think it is. The cost of an audit is relatively inexpensive. What I always tell people is the sooner you start preparing, the cheaper the whole process is. What happens a lot of times is a facility will not build out their facility to GMP specifications, and then they want to get GMP certified so they must move the hand washing station from the back of their facility to the front where the employee entrance is or things like that. The sooner these companies start thinking about it, the better and that’s basically what we’re trying to do is just educate the industry about that kind of preparation.
Green: cGMP and cGAP are perhaps more broadly accepted outside of the cannabis industry. Do cGMP and cGAP fall under the CSQ certification?
Williams: There are four ingredients that make up the CSQ standard. There are industry best practices, which are specific to just the cannabis industry. There are good manufacturing practices, or good agricultural practices, that are just accepted globally. Then we look at the Codex Alimentarius, which is the global food code. Every country mustwrite their federal rules on food based off this standard. We use the Codex when we’re talking about edibles and things like that. And then the last aspect of CSQ is the GFSI benchmarking requirements. So that’s kind of the basis of our program, making sure that the auditors have certain amount of audit hours, and we have training and processes in place for that. That’s where the GFSI benchmarks are coming out. So, all those four things kind of really create the CSQ standard.
Green: There are clear internal benefits to a company for holding to a quality standard. What are the downstream benefits to the companies that have CSQ? How do the end-users know about it?
Williams: I come from the food industry and if you go to the grocery store, you just assume that everything’s safe.Consumers don’t even think about the certifications that those companies must get to even be able to sell their product in retail stores. They don’t necessarily put those certifications on the packaging material, because as a consumer “SQF” means nothing to most consumers, right? It would only mean something if you’re in the industry.We’re trying to be different with CSQ and get more consumers aware of it. One of the things that we have is a database of certified facilities. Consumers will be able to say, “Okay, maybe I’m interested in this new brand. Are they certified to this program or not?” and be able to see that. We’re also trying to get companies to put the CSQ logo once they’re certified on their marketing materials.
Now, one thing that we cannot do yet is put the logo on the finished product packaging, because we don’t have a testing addendum, but we’re working on that. There’s not a lot of demand for it right now and it’s more expensive audit costs, where you’re talking about lab tests, and things like that. So, it’s something that we’re working on, but we haven’t fully developed yet.
Green: Next question is around d-8 THC and federal regulations. What’s your position on d-8 and how are you thinking about d-8 trends in the future?
Williams: d-8 THC itself as a product, I think it’s fine. I think if it’s made safely, we know all the components I think it’s fine from that aspect. The problem that we have right now is it’s not regulated. That’s where I think we need to have these states that have legalized THC or hemp to then implement rules and regulations and bring d-8 THC into those rules and regulations. And so maybe then it’s only those licensed facilities that are inspected by the state that are producing those products and not just some guy out of his garage. I think a lot of people right now are just wanting to ban it completely and I don’t think that’s the best approach. There’s nothing wrong with the product itself, it’s just how it’s being produced right now in the gray area where no one’s regulated.
Green: What in your personal life or in cannabis are you most interested in learning about?
Williams: I love what I do. I’m always looking at and reading regulations and then trying to learn something new. I’ve been going through organic certification training right now. At some point, CSQ will probably go down the route of having some sort of organic certification. So that’s been kind of what I’ve been working on and learning right now. But I’m a sponge and I like to absorb new information about the industry.
Green: Thanks Tyler, that concludes the interview!
bioMérieux, a leader in the in vitro diagnostics space and a supporter of the cannabis testing market, announced last month that they have achieved the first ever AOAC International approval for PCR Multiplex Detection of STEC and Salmonella in cannabis flower for their GENE-UP® PRO STEC/Salmonella Assay. The performance tested method approval for their new assay accomodates simultaneous enrichment and detection of STEC (Shiga Toxigenic Escherichia coli) and Salmonella spp. in cannabis samples.
The method is aimed at increasing efficiency in cannabis testing labs by reducing sample preparation time for microbiological testing. With the single enrichment and real-time multiplex PCR detection, bioMérieux says their new assay can provide reliable detection of STEC and Salmonella in 24 hours using just a single test.
PCR technology is one of the most widely utilized testing methods for detecting pathogens in a variety of matrices. bioMérieux claims it is easy to use, scientifically robust and reduces costs, time spent testing and errors.
Maria McIntyre, cannabis strategic operations business manager at bioMérieux, says that AOAC performance tested method approval is setting the bar for cannabis testing laboratories and furthering cannabis science. “AOAC International impacts cannabis science by setting analytical method standards that act as the benchmark for method validation,” says McIntyre. “This simplifies the validations needed by cannabis laboratories and assures the utmost confidence in product safety and human health.”
Practicing Law Institute Press’s Legal Guide to the Business of Marijuana: Cannabis, Hemp and CBD Regulation is a one-of-a-kind deep dive into the many regulations governing the industry. Aimed at attorneys representing clients in this space, the treatise offers guidance on a range of interrelated topics including state regulation of medical and non-medical cannabis; federal law, enforcement and preemption and their implications for employment, taxes and banking; and the various aspects of establishing and managing a cannabis enterprise, from growth to licensing, transport and distribution. We spoke with co-authors James T. O’Reilly, professor of Public Health Policy at the College of Medicine of the University of Cincinnati and author of leading references on food and drug law, and Edgar J. Asebey, a founding partner of Keller Asebey Life Science Law and a life sciences attorney with over twenty years of experience, about the intersection of the cannabis business and the law.
Q: From the legal industry’s perspective, how has this area of the law evolved over the past few years – and what would you advise clients in cannabis to look for when engaging legal assistance for their businesses?
James T. O’Reilly & Edgar J. Asebey: Over the past few years, we have seen a growing acceptance of the idea that lawfully serving the needs of cannabis consumers is a commendable business initiative. This evolution in thinking – tied to the myriad business opportunities cannabis presents – has given large, mainstream corporate law firms the incentive to grow practices and develop specialists in this area, which is a very positive development.
But it is not enough for lawyers to know their way around M&A and the capital markets; they must also have experience with federal regulatory bodies. As regulations continue to evolve, it is essential for practitioners to be familiar with the Food, Drug and Cosmetics Act as well as the Federal Trade Commission Act. The framework for regulating cannabis products already exists, as can be seen in the Warning Letters sent to hemp and CBD companies by both the Federal Trade Commission and Food and Drug Administration (as well as, most recently, the FDA and CDC’s warning about delta-8 THC). If a client places their hemp or CBD product into the stream of commerce, that product will be subject to FDA, FTC and relevant state laws. We strongly recommend seeking out advisors who truly understand these regulations and how they align with the regulatory agencies’ procedures and agendas.
Q: What are the most urgent legal and regulatory topics the industry is watching these days?
O’Reilly & Asebey: Our treatise follows and analyzes the most pressing legal issues facing those in the cannabis and hemp space. In our most recent edition, we add discussion of the Final Rule for the establishment of a domestic hemp production program. We think this is a significant development in that it attempted to address some of the industry’s criticism of some provisions found in the Interim Final Rule, particularly around issues of sampling and testing for THC content. The Final Rule clarified issues around THC percentage testing methodologies, but disappointed many in the industry by leaving in place the low 0.3% dry weight threshold for an acceptable hemp THC level. On the other hand, The Final Rule raises the threshold for a negligent violation from 0.5% to 1.0% total THC and limits the number of violations a grower can receive in one year to one, easing potential penalties for violations.
Of course, the regulation of CBD products is on the minds of many in the industry. Key questions remain about whether cannabinoids such as delta-8 THC can be lawfully sold. Since the FDA has provided no clear guidance with regard to the sale and use of CBD and other hemp-derived cannabinoid-containing products, well-meaning businesses find themselves operating in a regulatory gray area. While some states have raced to place delta-8 THC on their controlled substances lists or otherwise regulate it, at the federal level it remains unclear. Our book provides a legal argument showing that current regulations support the lawful production and sale of delta-8 THC. To date, this and other legal arguments have not been tested in the courts and, without FDA guidance, the delta-8 THC sector will remain gray.

The cannabis industry is approaching a crossroads. While cultivators must ensure they are getting the greatest yield per square foot, an increasingly competitive landscape and sophisticated consumer means growers must also balance the need for volume with quality, consistent and award-winning cannabis strains.
Tissue culture propagation represents a significant leap forward in cannabis cultivation, ultimately benefiting both the grower and the consumer. The proprietary technology behind our sterilization and storage process results in the isolation of premium cannabis genetics in a clean, contaminant-free environment. Since our inception, we’ve been focused on setting a higher standard in medical (and one day adult use) cannabis by growing craft cannabis on a commercial scale through utilization of this cutting-edge cultivation technique. When taken in total, Maitri boasts access to a library of 243 unique cannabis strains, one of the largest collections in the U.S.
Trouble with Traditional Cultivation
Pathogens, insects and cross contamination all threaten the viability and value of cannabis plants. In many ways, current cannabis cultivation techniques compound these issues by promoting grams per square foot above all else and packing plants into warehouse sized grows where issues can quickly spread.
In these close quarters, pests can swiftly move from plant to plant, and even from generation to generation when propagating from clones or growing in close quarters. Similarly, pathogens can leap between susceptible plants, damaging or killing plants and cutting into a cultivator’s bottom line.
Hemp tissue culture samples
Of particular concern is hop latent viroid. Originally identified in hops, a genetic relative of cannabis, this infectious RNA virus has torn through the cannabis industry, endangering genetics, causing sickly plants and reducing yields. Plants cloned using traditional methods from an infected mother are vulnerable to the disease, making hop latent viroid a generational issue.
Minimizing or even eliminating these threats helps to protect the genetic integrity of cannabis strains and ensures they can be enjoyed for years to come. That is where the sterilization stage in tissue culture cultivation stands out.
Like cloning, tissue culture propagation offers faster time to maturity than growing from seed, allowing for a quicker turnaround to maximize utility of space, without overcrowding grow rooms. However, it also boasts a clean, disease-free environment that allows plants to thrive.
Tissue Culture Cultivation
Tissue culture cultivation allows for viable plant tissue to be isolated in a controlled, sterilized environment. Flowering plants can then be grown from these stored genetics, allowing for standardization of quality strains that are free of contamination and disease from the very beginning. Tissue culture cultivation also takes up less room than traditional cloning, freeing up valuable square footage.
A large tissue culture facility run in the Sacramento area that produces millions of nut and fruit trees clones a year.
This propagation process begins with plants grown to just before flowering and harvested for their branch tips. These branch tips undergo a sterilization process to remove any environmental contamination. This living plant material (known as explants) gets fully screened and tested for potential contaminants.
If it passes, the sample is stabilized and becomes part of the Maitri genetic library for future cultivation. If any contamination is discovered, the plant is selected for meristem isolation, an intensive isolation technique at the near cellular level.
Once sterilized and verified to be clean, the samples — often just an inch tall — are isolated into individual test tubes in our proprietary nutrient-rich medium for storage indefinitely. The cuttings are held in these ideal conditions until tapped for cultivation. This process allows Maitri to maintain an extensive library of clean, disease-free cannabis genetics ready to be grown.
Benefits for Medical Cannabis Patients
Tissue culture creates exact genetic replicas of the source plant
One of the chief benefits of tissue culture propagation is that it creates exact genetic replicas of the source plant. This allows growers like Maitri to standardize cannabis plants, and thus the cannabis experience. That means patients can expect the same characteristics from Maitri grown strains every time, including effects, potency and even taste and smell. Keeping reliable, top quality strains in steady rotation ensures patients have access to the medicine they need.
Preserving Plant Genetics
Beyond the benefits that tissue culture cultivation provides for the patient, this approach to testing, storing and growing cannabis plants also goes a long way towards protecting cannabis genetics into the future.
Cannabis strains are constantly under assault from pests and disease, potentially destroying the genetics that make these strains so special. Over-breeding and a dwindling demand for heirloom strains also threatens the loss of some individual plant genetics. Having a collection of genetics readily available means we can quickly cultivate strains to best meet consumer demand. Additionally, maintaining a rich seed bank that features both legacy and boutique strains allows us to have options for future tissue culture cultivation or for future new strain development.
Advancing Cannabis Research
Due to federal prohibition, researching cannabis, especially at the university level, can be extremely difficult. Additionally, the cannabis material that researchers have access to is largely considered to be subpar and wildly inconsistent, placing another barrier to researching the physiological effects of the plant. Clean, safe and uniform cannabis is a necessity to generate reliable research data. Utilizing tissue culture cultivation is a smart way to ensure researchers have access to the resources they need to drive our understanding of the cannabis plant.
Automated extraction equipment and technologies are rapidly becoming the standard in the extraction sector of the cannabis industry. Like most evolving industries, manual and operator driven processes are what starts an industry, but with explosive growth, demand for increased safety, efficiency and repeatability grows. Specifically within the cannabis industry, we’re noticing a rising demand for higher quality extracts and a safer, more repeatable environment for cannabinoid extraction. These are all reasons for the industry making a shift towards automated extraction equipment and technologies.
What Automation Looks Like in Cannabis Extraction
Automation in the cannabis industry doesn’t necessarily mean implementing robotics and creating operator-less facilities; It typically refers to automated process control. Traditional, older technologies are manual and operator-driven. This means the equipment operator is in control of all parameters of the process, which leads to inconsistencies throughout the process caused by human error. As the extraction process has many steps: ethanol holding, chilling, extraction agitation, extraction discharge, extraction solvent removal, particle filtration, semi saturated solution storage, and so much more that involves valves, pumps and controls between each piece of the process, it becomes difficult to control such a tedious process manually. When all of these processes are controlled and monitored using proper automation technology, facilities can safely ensure that each batch is run following the same process and parameters accordingly. This is critical for product consistency, a concern for manufacturers and many end-consumers. As the cannabis industry grows, matures and makes its way closer to federal legalization, product safety and consistency become a top-priority for everyone involved.
Greater Quality Control of End-Products
Automated extraction processes ensures that the same solvent ratios are used batch-to-batch
Consistency and repeatability are just as important for cannabis processors as they are for standard food or pharmaceutical processors. Deploying a manual process of equipment operating and monitoring leaves far too much room for human error, and doesn’t provide the level of control needed for the industry as it continues to progress toward stricter product regulations and requirements. On the other hand, an automated extraction process ensures that the same solvent ratios are used batch-to-batch, the same extraction temperatures and recipe parameters are implemented, the same pump and process flow rates are deployed, and all processes are repeatable, predictable and scalable while producing a safe, consistent product.
Fewer Bottlenecks
The benefits of automated extraction are directly tied to establishing greater efficiency in processes. Efficiency can be experienced via less scrap product from unmanaged batches and/or less labor to operate and control the process. Automation means allowing a recipe-driven control system monitor and control the process, eliminating process bottlenecks that have been notorious for destroying productivity in manual extraction operations.
As Cannabis Extraction Processes Become Automated, They Become Safer.

A team is what drives any business forward. The safety of that team needs to be a top priority for any business leader. As cannabis extraction processes become automated, they become safer. With less equipment interaction, the likelihood for human error that could lead to safety hazards significantly decreases. Properly programmed automation can establish advanced system interlocks that check multiple points throughout the process for irregularities, and can halt a machine based on these irregularities it detects. That level of process monitoring and control is only available when automation and PLC logic controls equipment.
Data Collection and Validation
When we tie all the benefits of extraction automation together, it makes for a far more attractive system than traditional,manual processes that we’re used to seeing in the cannabis industry. In addition to the major benefits listed above, automation gives a superior level of data collection for process improvements and process validation which is key in cGMP or EU-GPM facilities. This is the future for every processing facility in the arena of cannabis. As the industry matures, it will continue to become more competitive. Facilities with automation will have the capacity to maximize their process efficiencies, produce a far superior and more consistent end–product and will have a competitive advantage in the extraction sector.
Lean management or Lean thinking is a process for continuous improvement that can be applied to any business. Most frequently Lean is attributed to the manufacturing sector due to its origins in Japan at the Toyota Motor Company. Lean originated in post-war Japan where resources were scarce as the country rebuilt itself after World War II. The scarcity of resources forced the Japanese to do more with less which manifested itself within the Toyota organization as the Toyota Production System from which Lean originated.
Today, Lean thinking is being applied to every industry and we believe that the cannabis industry, and in particular laboratories, can benefit tremendously from its principals.
What Is Lean and How Does it Apply to Cannabis?
Lean thinking is a set of powerful tools for any business or organization that wants to be the best in their industry and deliver superior value their customers. This is especially relevant to the fast-growing cannabis and hemp testing industry where customers demand fast turnaround times and error-free results.
The reason that Lean applies to all businesses and especially the cannabis industry is because of its focus is on eliminating waste. Waste comes in many forms including defects, waiting time, extra motion, excess inventory, transportation, over production, over processing and underutilized talent.
Companies that adopt Lean management eliminate waste using a wide variety of tools that help surface issues and eliminate the root causes. When companies eliminate waste, they simultaneously improve both their speed and quality, two attributes that customers really care about. Given the fast-changing nature of the cannabis industry and differences state by state, we believe that using Lean thinking to eliminate waste is critical to being a top performing business in the cannabis industry.
One important tool that many businesses begin with is known as 5S or 6S. At our laboratory we recently implemented 6S to organize both our office and laboratory spaces. 6S is a process improvement tool that stands for Sort, Set in Order, Shine, Standardize, Sustain and Safety. The process involves each technician or analyst assessing their areas and asking critical questions such as: Can I easily reach everything I need for this test or process? Is there wasted motion due to the placement of items within the lab? Can I easily tell how much consumable inventory I have on hand at a glance?
This process also helps improve safety because the workspace is better organized, easier to navigate and designed with safety in mind. Each person is responsible for maintaining their workspace and regular audits by rotating teammates, helping drive continuous improvement to our 6S. It is a fundamental process for any business starting to adopt Lean thinking.
Another very helpful process that any cannabis business can implement is the Gemba walk. Gemba is the Japanese word for “actual place” and refers to the place in a business where value is created for the customer. Value in our cannabis business is created in our testing lab. By improving everything in our testing lab we improve our quality and speed for our customers. In our laboratory we begin the Gemba walk as a team reviewing our key performance indicators (KPIs). From there, the management team visits each station to review additional KPIs and discuss any issues that group may be having. We try to surface issues, however small they may be, so that they are solved and hopefully eliminated. This process is key to helping us keep a pulse on the lab, engaging employees and better understand the improvements that need to be made.
How to Implement Lean Processes
Without quality results, a testing laboratory does not really have a product or service to offer
Lean thinking is a very accessible set of tools. Unfortunately, it is quite difficult to implement because of the dedication that it requires. Implementing Lean and changing the culture requires a significant amount of time, investment in training and management commitment. Time and capital for training can be scarce at some businesses in the cannabis industry. For the businesses with capital, it is extremely important that management commit to implementing Lean and changing their culture. Without the support of the executive team most businesses stop implementing new procedures and revert to how they are used to operating. It is also common for changes in management to result in lean becoming deprioritized in place of a new initiative.
If the executive team is inexperienced in Lean management, it will be important to find a Lean consultant that can guide the training and events. A Lean consultant should be able to provide you with thorough training on each tool and help your business implement them in real time to improve the business. The training and knowledge gained during these events are extremely valuable and practical tools that every employee can use.
Results From Implementing a Lean Organization
If a business is able to successfully implement Lean management the results for their customers can be dramatic. In the laboratory setting, turnaround times will be reduced, and more importantly, will remain consistent despite fluctuations in sample volume. Faster turnaround times for cannabis companies means that they can bring inventory to market faster which can be critical for supply constrained businesses.
Additionally, implementing Lean helps reduce the number of errors, rework and retests so the quality of the results for the customer is dramatically improved. Root cause issues are solved, processes are updated and then shared with the entire team so that everyone can learn and benefit from the improvement. Without quality results, a testing laboratory does not really have a product or service to offer so it is critical to get it right every time.
All areas of the cannabis industry are becoming more competitive, and it is important for every business to make sure they can stay competitive considering changing market dynamics. Lean management has helped businesses in other industries stand apart from the rest and we believe that the cannabis industry will be no different. Academic literature has studied and documented the positive impact that Lean has on businesses globally. Lean management has repeatedly shown that businesses that can truly implement Lean thinking in everything that they do will have an inherent advantage because they’ll be faster, more agile, higher quality, more efficient and focused entirely on creating value for their customer.
Facility layout and design are important components of overall operations, both in terms of maximizing the effectiveness and efficiency of the process(es) executed in a facility, and in meeting the needs of personnel. Prior to the purchase of an existing building or investing in new construction, the activities and processes that will be conducted in a facility must be mapped out and evaluated to determine the appropriate infrastructure and flow of processes and materials. In cannabis markets where vertical integration is the required business model, multiple product and process flows must be incorporated into the design and construction. Materials of construction and critical utilities are essential considerations if there is the desire to meet Good Manufacturing Practice (GMP) compliance or to process in an ISO certified cleanroom. Regardless of what type of facility is needed or desired, applicable local, federal and international regulations and standards must be reviewed to ensure proper design, construction and operation, as well as to guarantee safety of employees.
Materials of Construction
The materials of construction for interior work surfaces, walls, floors and ceilings should be fabricated of non-porous, smooth and corrosive resistant surfaces that are easily cleanable to prevent harboring of microorganisms and damage from chemical residues. Flooring should also provide wear resistance, stain and chemical resistance for high traffic applications. ISO 22196:2011, Measurement Of Antibacterial Activity On Plastics And Other Non-Porous Surfaces22 provides a method for evaluating the antibacterial activity of antibacterial-treated plastics, and other non-porous, surfaces of products (including intermediate products). Interior and exterior (including the roof) materials of construction should meet the requirements of ASTM E108 -11, Standard Test Methods for Fire Tests of Roof Covering7, UL 790, Standard for Standard Test Methods for Fire Tests of Roof Coverings 8, the International Building Code (IBC) 9, the National Fire Protection Association (NFPA) 11, Occupational Safety and Health Administration (OSHA) and other applicable building and safety standards, particularly when the use, storage, filling, and handling of hazardous materials occurs in the facility.
Utilities
Critical and non-critical utilities need to be considered in the initial planning phase of a facility build out. Critical utilities are the utilities that when used have the potential to impact product quality. These utilities include water systems, heating, ventilation and air conditioning (HVAC), compressed air and pure steam. Non-critical utilities may not present a direct risk to product quality, but are necessary to support the successful, compliant and safe operations of a facility. These utilities include electrical infrastructure, lighting, fire detection and suppression systems, gas detection and sewage.
Water
Microbial monitoring methods can include frequent/consistent testing
Water quality, both chemical and microbial, is a fundamental and often overlooked critical parameter in the design phase of cannabis operations. Water is used to irrigate plants, for personnel handwashing, potentially as a component in compounding/formulation of finished goods and for cleaning activities. The United States Pharmacopeia (USP) Chapter 1231, Water for Pharmaceutical Purposes 2, provides extensive guidance on the design, operation, and monitoring of water systems. Water quality should be tested and monitored to ensure compliance to microbiological and chemical specifications based on the chosen water type, the intended use of the water, and the environment in which the water is used. Microbial monitoring methods are described in USP Chapter 61, Testing: Microbial Enumeration Tests3and Chapter 62, Testing: Tests for Specified Microorganisms 4, and chemical monitoring methods are described in USP Chapter 643, Total Organic Carbon 5, and Chapter 645, Water Conductivity6.Overall water usage must be considered during the facility design phase. In addition to utilizing water for irrigation, cleaning, product processing, and personal hygiene, water is used for heating and cooling of the HVAC system, fogging in pest control procedures and in wastewater treatment procedures A facility’s water system must be capable of managing the amount of water required for the entire operation. Water usage and drainage must meet environmental protection standards. State and local municipalities may have water usage limits, capture and reuse requirements and regulations regarding runoff and erosion control that must also be considered as part of the water system design.
Lighting
Lighting considerations for a cultivation facility are a balance between energy efficiency and what is optimal for plant growth. The preferred lighting choice has typically been High Intensity Discharge (HID) lighting, which includes metal halide (MH) and high-pressure sodium (HPS) bulbs. However, as of late, light-emitting diodes (LED) systems are gaining popularity due to increased energy saving possibilities and innovative technologies. Adequate lighting is critical for ensuring employees can effectively and safely perform their job functions. Many tasks performed on the production floor or in the laboratory require great attention to detail. Therefore, proper lighting is a significant consideration when designing a facility.
HVAC
Proper lighting is a significant consideration when designing a facility.
Environmental factors, such as temperature, relative humidity (RH), airflow and air quality play a significant role in maintaining and controlling cannabis operations. A facility’s HVAC system has a direct impact on cultivation and manufacturing environments, and HVAC performance may make or break the success of an operation. Sensible heat ratios (SHRs) may be impacted by lighting usage and RH levels may be impacted by the water usage/irrigation schedule in a cultivation facility. Dehumidification considerations as described in the National Cannabis Industry Association (NCIA) Committee Blog: An Introduction to HVACD for Indoor Plant Environments – Why We Should Include a “D” for Dehumidification 26 are critical to support plant growth and vitality, minimize microbial proliferation in the work environment and to sustain product shelf-life/stability. All of these factors must be evaluated when commissioning an HVAC system. HVAC systems with monitoring sensors (temperature, RH and pressure) should be considered. Proper placement of sensors allows for real-time monitoring and a proactive approach to addressing excursions that could negatively impact the work environment.
Compressed Air
Compressed air is another, often overlooked, critical component in cannabis operations. Compressed air may be used for a number of applications, including blowing off and drying work surfaces and bottles/containers prior to filling operations, and providing air for pneumatically controlled valves and cylinders. Common contaminants in compressed air are nonviable particles, water, oil, and viable microorganisms. Contaminants should be controlled with the use appropriate in-line filtration. Compressed air application that could impact final product quality and safety requires routine monitoring and testing. ISO 8573:2010, Compressed Air Specifications 21, separates air quality levels into classes to help differentiate air requirements based on facility type.
Electrical Infrastructure
Facilities should be designed to meet the electrical demands of equipment operation, lighting, and accurate functionality of HVAC systems. Processes and procedures should be designed according to the requirements outlined in the National Electrical Code (NEC) 12, Institute of Electrical and Electronics Engineers (IEEE) 13, National Electrical Safety Code (NESC) 14, International Building Code (IBC) 9, International Energy Conservation Code (IECC) 15 and any other relevant standards dictated by the Authority Having Jurisdiction (AHJ).
Fire Detection and Suppression
“Facilities should be designed so that they can be easily expanded or adjusted to meet changing production and market needs.”Proper fire detection and suppression systems should be installed and maintained per the guidelines of the National Fire Protection Association (NFPA) 11, International Building Code (IBC) 9, International Fire Code (IFC) 10, and any other relevant standards dictated by the Authority Having Jurisdiction (AHJ). Facilities should provide standard symbols to communicate fire safety, emergency and associated hazards information as defined in NFPA 170, Standard for Fire Safety and Emergency Symbols27.
Gas detection
Processes that utilize flammable gasses and solvents should have a continuous gas detection system as required per the IBC, Chapter 39, Section 3905 9. The gas detection should not be greater than 25 percent of the lower explosive limit/lower flammability limit (LEL/LFL) of the materials. Gas detection systems should be listed and labeled in accordance with UL 864, Standard for Control Units and Accessories for Fire Alarm Systems16 and/or UL 2017, Standard for General-Purpose Signaling Devices and Systems 17 and UL 2075, Standard for Gas and Vapor Detectors and Sensors18.
Product and Process Flow
Product and process flow considerations include flow of materials as well as personnel. The classic product and process flow of a facility is unidirectional where raw materials enter on one end and finished goods exit at the other. This design minimizes the risk of commingling unapproved and approved raw materials, components and finished goods. Facility space utilization is optimized by providing a more streamlined, efficient and effective process from batch production to final product release with minimal risk of errors. Additionally, efficient flow reduces safety risks to employees and an overall financial risk to the organization as a result of costly injuries. A continuous flow of raw materials and components ensures that supplies are available when needed and they are assessable with no obstructions that could present a potential safety hazard to employees. Proper training and education of personnel on general safety principles, defined work practices, equipment and controls can help reduce workplace accidents involving the moving, handling, and storing of materials.
Facilities Management
Facilities management includes the processes and procedures required for the overall maintenance and security of a cannabis operation. Facilities management considerations during the design phase include pest control, preventative maintenance of critical utilities, and security.
Damage from whiteflies, thrips and powdery mildew could be prevented with an appropriate PCP
A Pest Control Program (PCP) ensures that pest and vermin control is carried out to eliminate health risks from pests and vermin, and to maintain the standards of hygiene necessary for the operation. Shipping and receiving areas are common entryways for pests. The type of dock and dock lever used could be a welcome mat or a blockade for rodents, birds, insects, and other vermin. Standard Operating Procedures (SOPs) should define the procedure and responsibility for PCP planning, implementation and monitoring.
Routine preventative maintenance (PM) on critical utilities should be conducted to maintain optimal performance and prevent microbial and/or particulate ingress into the work environment. Scheduled PMs may include filter replacement, leak and velocity testing, cleaning and sanitization, adjustment of airflow, the inspection of the air intake, fans, bearings and belts and the calibration of monitoring sensors.
In most medical cannabis markets, an established Security Program is a requirement as part of the licensing process. ASTM International standards: D8205 Guide for Video Surveillance System 23, D8217 Guide for Access Control System[24], and D8218 Guide for Intrusion Detection System (IDS) 25 provide guidance on how to set up a suitable facility security system and program. Facilities should be equipped with security cameras. The number and location of the security cameras should be based on the size, design and layout of the facility. Additional cameras may be required for larger facilities to ensure all “blind spots” are addressed. The facility security system should be monitored by an alarm system with 24/7 tracking. Retention of surveillance data should be defined in an SOP per the AHJ. Motion detectors, if utilized, should be linked to the alarm system, automatic lighting, and automatic notification reporting. The roof area should be monitored by motion sensors to prevent cut-and-drop intrusion. Daily and annual checks should be conducted on the alarm system to ensure proper operation. Physical barriers such as fencing, locked gates, secure doors, window protection, automatic access systems should be used to prevent unauthorized access to the facility. Security barriers must comply with local security, fire safety and zoning regulations. High security locks should be installed on all doors and gates. Facility access should be controlled via Radio Frequency Identification (RFID) access cards, biometric entry systems, keys, locks or codes. All areas where cannabis raw material or cannabis-derived products are processed or stored should be controlled, locked and access restricted to authorized personnel. These areas should be properly designated “Restricted Area – Authorized Personnel Only”.
Future Expansion
The thought of expansion in the beginning stages of facility design is probably the last thing on the mind of the business owner(s) as they are trying to get the operation up and running, but it is likely the first thing on the mind of investors, if they happen to be involved in the business venture. Facilities should be designed so that they can be easily expanded or adjusted to meet changing production and market needs. Thought must be given to how critical systems and product and process flows may be impacted if future expansion is anticipated. The goal should be to minimize down time while maximizing space and production output. Therefore, proper up-front planning regarding future growth is imperative for the operation to be successful and maintain productivity while navigating through those changes.

On September 14, the FDA published a consumer update on their website, seeking to educate the public and offer a public health warning on delta-8 tetrahydrocannabinol, otherwise known as delta-8 THC.
For the uninitiated, delta-8 THC is a cannabinoid that can be synthesized from cannabidiol (CBD) derived from hemp. It is an isomer of delta-9 THC, the more commonly known psychoactive cannabinoid found in cannabis. Delta-8 THC does produce psychoactive effects, though not quite as much as its better-known cousin, delta-9 THC.
Due to loopholes in federal and state laws, namely the 2018 Farm Bill specifying that hemp must contain less than 0.3% Delta-9 THC, delta-8 THC is technically legal across the country. It grew in popularity across the United States very quickly over the past year, largely due to online sales.
Following the surge in sales, a number of states including Colorado, Alaska, Arizona, Arkansas, Delaware, Idaho, Iowa, Mississippi, Montana, Rhode Island, Utah and Washington have implemented some form of regulation or outright ban on products containing delta-8 THC. Christopher Hudalla, president and chief scientific officer of ProVerde Laboratories, told Chemical & Engineering News that he has a lot of safety concerns about the whole delta-8 THC craze. Hudalla says he’s more concerned about the processing involved to produce it in large quantities. “These are pretty aggressive synthetic conditions that use strong acids,” Hudalla says. “They might be using strong bases to neutralize. They can use metal catalysts. I hear different people doing it different ways.”
The FDA’s consumer update included this picture at the top of the page
The FDA shares similar concerns. Their fourth point in the consumer update mentions that delta-8 THC products “often involve use of potentially harmful chemicals” in its production. They even claim that some manufacturers might be using unsafe household chemicals to synthesize delta-8 THC. “The final delta-8 THC product may have potentially harmful by-products (contaminants) due to the chemicals used in the process, and there is uncertainty with respect to other potential contaminants that may be present or produced depending on the composition of the starting raw material,” reads the FDA report.
In their consumer update, they note that between December 2020 and July 2021, they received 22 adverse event reports. Of the 22 reports, 14 were hospitalized following ingesting a delta-8 THC product. Notably, those reports included reactions consistent with symptoms from overconsumption of delta-9 THC, such as vomiting, hallucinations, trouble standing, and loss of consciousness.
The chemical structure of Delta 8 THC.
The FDA says that national poison control centers received 661 cases of delta-8 THC products, with 41% being unintentional exposure, 39% involved pediatric patients and 18% required hospitalization.
In the consumer update, they tell the public that delta-8 THC products have not been evaluated by the FDA and that they “may be marketed in ways that put the public health at risk.” This includes marketing it as a hemp product, which it is. Still though, many consumers associate hemp products with somewhat innocuous things, like CBD oil, which is mostly harmless.
The FDA also mentions in the update that delta-8 THC does have psychoactive and intoxicating effects. The FDA says they are notifying the public about the delta-8 THC due to an uptick in adverse event reports, marketing that is appealing to children and concerns regarding manufacturing with unsafe chemicals and contaminants.

Derek Smith: We’ve been working in cannabis for five years, publishing best practices and capturing data to inform governments and utilities on how much energy is being used. Our mission is to help producers become more efficient in their use of resources. In addition to informing policies that support producers, we also engage utilities to help them evaluate efficient technologies, so they can put incentives on them and so they can help buy down the cost for cannabis producers to install more efficient technologies.
