Congress Wants YOU To Make Safe Products.

By David Vaillencourt

Recently, Congress requested detailed information regarding the regulation of CBD and other cannabinoids. This comes on the heels of frustration around federal inaction with regards to cannabinoid-containing products produced from Cannabis sativa L. plant extracts that can be classified as “hemp” products amidst the clear need for safety standards that goes above and beyond state minimum compliance requirements.

A Historical Deja Vu?

The author will be joined by his colleagues leading the Seed to Sale Safety Workshop on October 16 at the Cannabis Quality Conference. Click here to learn more. Product safety standards predate the birth of our nation (and many others). From the days of the first pharmacopeias which rival the oldest documented use of the cannabis plant, to modern regulations, the quest for safety has been a constant theme. But as the saying goes “Old habits die hard,” but so do safety issues. From peanuts to thalidomide and tobacco, we’ve seen this movie before – and it is time for a new ending.

A Universal Desire for Safety

Whether you are an investor, executive, technician or anywhere in between – nobody in the cannabis industry (and all its end uses, including industrial hemp) wants to knowingly produce unsafe products. The risks of ignoring safety are real and tangible. Whether it is 20+ years in jail for being an executive of a company that knowingly sold adulterated products and was linked to seven deaths or 10,000+ deformed children, many of whom died at birth because of a drug approved for morning sickness – there is no shortage of case studies we can learn from. Even cannabis has been known to cause injury and death in consumers – not because of the d9-THC, but the impurities. As the industry continues to innovate and develop new product form factors – whether it is new delivery methods of d9-THC in soluble beverage forms, or the rise of manufactured cannabinoids in unregulated marketplaces – it’s critical to understand the risks of your entire production process and to mitigate them. No cannabis company is immune from making costly and dangerous mistakes. It’s not just about compliance – it’s about public health and safety.

Safety Can Be a Sticky Subject

Safety is indeed a complex subject, especially when it comes to cannabis products. For instance, acceptable limits for microbial contaminants for the inflorescence of a Cannabis sativa L. plant are quite literally all over the map. What about the route of administration? Take an inhaled product (like a vape pen) vs. an ingested product (e.g. an edible). Many outdoorsy people like myself may enjoy the smell of cooking s’mores over a campfire, but the particles and VOCs can irritate our lungs, especially when exposed over long periods of time. We aren’t inhaling those s’mores – so the production of the marshmallow, chocolate and graham crackers come with different risks we need to evaluate. It’s not just about the product – it’s how it’s consumed.

Safety Standards the Fabric of Our Society

Standards are unsung heroes of our daily lives. Whether it’s to keep planes from falling out of the sky, cribs and dressers from crushing young children, preventing train derailments or ensuring the safety of our food and medical products – standards keep us protected – just like grandma’s quilt. The absence of standards can be expensive, and anyone familiar with the accusations of d9-THC lab-shopping and inflated label claims knows that the cannabis industry is the poster child for this.

Congress has long recognized the importance of standards in protecting everyday consumers, as demonstrated by numerous legislative acts. A few notable and relevant ones to cannabis are below:

  • 1848 Drug Importation Act: First major act that combated the importation of substandard – adulterated drugs imported from overseas into the nation which was having a major impact on soldiers of the Mexican-American War.  This Act included legal requirements for drugs to meet the US Pharmacopeia’s standards for strength, quality, and purity.
  • 1906 Food and Drugs Act: After an increase in adulterated and misbranded foods and drugs – made famous by Upton Sinclair’s The Jungle, the relentless work of Dr. Harvey Wiley, a Chief Chemist with the then US Department of Agriculture and his “poison squad” – led to significant oversight of adulterated food and drugs including legal adherence to the US Pharmacopeia and paved the way for the current FDA.
  • 1938 Food Drug, Cosmetic Act: Shortcomings in the 1906 Food and Drugs Act were catalyzed by over 100 deaths after a wonder drug that was analogous to antifreeze led to an outcry that led to the passage of the FDC&A. From factory inspections, to strict marketing and label requirements, to legally enforceable food standards and tolerances for certain poisonous substances – the FDA was given substantial more oversight to protect the growing United States. It also expressly recognized USP quality standards for medicines with USP standards also binding for any dietary supplement manufacturer that labels their products as being compliant with USP specifications.
  • 1994 Dietary Supplement Health Education Act (DSHEA) defined and regulated dietary supplements which carved out significant exemptions for the dietary and herbal supplement industry from most FDA drug regulations. This act has been met with significant controversy as it greatly limited the FDA’s capacity to ban or restrict supplements until evidence of a major safety or adverse event is tied to the product of concern.
  • 1995 National Technology Transfer Advancement Act (NTTAA) – A lesser known act that is focused on standards and technology that requires participation of federal agencies in voluntary consensus standards bodies. Extending beyond foods and medicines – this act covers a broad array of infrastructure and technology regulations that ensure the fabric of our society operates (largely) without issue.

Over 1,000 ASTM standards are incorporated by reference in the US Code of Federal Regulations across nearly 30 federal agencies (searchable here), a demonstration of the value and impact public voluntary standards have in our society.

At the FDA, ASTM standards are used every day to keep us safe. Whether it is to measure the absorbency of tampons (21 CFR 801.430), enforce safety specifications of synthetic and natural wax coatings that are used to coat much of our produce, gummies and more (21 CFR 178.3770), quantifying the impurities in our bottled water (21 CFR 165.110) and many more.They have long been recognized as the de facto minimum standards that balance the need to protect consumers without imposing undue burdens on innovation by industry.

The process of developing an ASTM standard, which was developed and used to keep our trains from derailing 125 years ago, is now the home of 510+ cannabis industry specific standards. Whether it’s acceptable water activity levels in cannabis flower, a truly universal symbol to alert consumers of intoxicating cannabinoids, medical cannabis flower specifications developed in close guidance of the US Pharmacopeia, or how to apply the principles of HACCP to cannabis products, a lot of the hard work has already been done for the industry. It’s simply a matter of knowing where to look and how to use them!

The path to safe and sustainable cannabis products is clear, and the tools are available. It’s time that we learn from the past, apply the standards of the present and mitigate the risks of the future. Now more than ever before, it’s easy to make safe cannabis products and a credible marketplace not just a goal, but a reality.

Safety & Compliance in the Absence of Regulatory Clarity & Consistency

By Joel Chappelle
No Comments

As the legal landscape surrounding cannabis continues to evolve, the creation of robust, sensible and consistent safety regulations remains stalled. A patchwork of broadly inconsistent state rules and regulations, along with years of federal inaction and policy stagnation have the potential to create significant risks for consumers. Given the industry’s explosive, multi-billion-dollar growth, consumers have access to an ever-increasing number of products produced by an increasing number of actors, pursuant to widely divergent standards and rules. Given this, the industry would be well-served to take on the responsibility of promulgating a coherent regulatory framework with robust (but sensible) safety regulations. The importance of collaboration among cannabis industry stakeholders cannot be overstated if we are to develop and adopt consistent standards that guarantee product safety at every step of the supply chain.

Joel Chappelle, along with several renowned experts, will lead the Seed to Sale Safety Workshop at the Cannabis Quality Conference this October 16 in New Jersey. Click here to learn more. Inconsistencies in safety standards and regulations open the door to a range of potential hazards, including contaminant risk, labeling accuracy, potency quantification and many others. Absent a clear understanding of seed-to-sale risks, many of which are not even mentioned in state regulations, cannabis companies face significant exposure, often without even knowing it.

To mitigate these risks, it is vitally important for the cannabis industry to collaborate in the ongoing development of safety standards. This means understanding and implementing safety measures starting with the cultivation process. Careful consideration should be given to factors such as the use of pesticides and herbicides, soil quality and irrigation methods. Standardized safety testing to ensure uniformity between products for potency, contaminants, heavy metals and microbial organisms is crucial to consumer safety. Accurate and comprehensive labeling is likewise necessary for consumers to be adequately informed.

For as long as consistent state and federal guidelines governing cannabis safety remain elusive, the need for industry self-regulation will be paramount. Cannabis companies must work together to share best practices, establish standard operating procedures and adopt stringent safety measures. By promoting transparency and collaboration, stakeholders can build credibility and consumer trust while fostering a safer and more reputable industry.

As the industry continues to grow, it is incumbent upon all stakeholders to continue prioritizing consumer safety through, among other things, a focus on education and inter-industry collaboration, if we are to continue cultivating a trustworthy and sustainable cannabis market for the future. The path forward will require stakeholders to pursue continuous education, improvement, and collaboration in the development of a holistic safety framework capable of ensuring consumer safety.

Hop Latent Viroid (HLVd) & Pathogen Diagnostics: A Comprehensive Overview

By Tassa Saldi, Ph.D.
1 Comment

Hop latent viroid (HLVd) has gained attention as the molecular cause of “dudding disease” and is causing significant economic losses in the cannabis industry.1,2 Estimates indicate that upwards of 4 billion dollars of market value are lost each year to this pathogen alone.3 The impact of HLVd on cannabis plants necessitates the development and implementation of effective pathogen diagnostics to mitigate its spread and minimize crop damage. With collaborative research efforts, we can gain valuable insights into the characteristics, spread, symptoms and preventive measures associated with HLVd in the cannabis industry.

Viroids: A Brief Overview

Figure 1: Virus vs Viroid

Viroids are unique infectious agents composed solely of genetic material, distinct from viruses. Unlike viruses, viroids lack a protective protein layer and solely rely on the host plant for replication and spread. Their stability and ability to persist in various environments make viroids a formidable threat to plant health.

Hop Latent Viroid: Origin and Global Spread

Hop latent viroid was initially identified in hop plants in 19884 and was found to be largely asymptomatic in this crop. Consequently, HLVd has spread worldwide, mostly unchecked by the hops industry. This pathogen has been identified on most continents and in some fields more than 90% of hops plants are infected.5 Hop latent viroid very likely jumped from hops into cannabis, due to similar genetics. The timing and mechanism of cross-species transmission to cannabis remains unknown, but the prevalence of HLVd suggests this viroid has been circulating within cannabis for an extended period. Data collected at TUMI Genomics indicates that HLVd is present in all states in the United States where cannabis is legal as well internationally including; Canada, the United Kingdom, France, the Netherlands, Thailand, Austria and Switzerland.

Symptoms and Impacts on Cannabis Plants 

Figure 2: HLVd Symptoms

HLVd exhibits a wide range of symptoms, which can vary from severe to subtle, affecting the growth, leaf development, flower quality and overall vitality of cannabis plants. Understanding these symptoms is crucial for timely diagnosis and appropriate disease management strategies.  However, HLVd can also present asymptomatically, especially in vegetative plants. The only way to determine if your plants are infected is by routine molecular testing.

Modes of Transmission

Mechanical Transmission: HLVd primarily spreads mechanically through contact with infected sap during activities like trimming and handling. Additionally, transmission through contaminated water and the potential role of insects, fungal pathogens and seeds in spreading HLVd have also been observed.

Seed Transmission: Although no published studies exist in cannabis describing the frequency of seed transmission, HLVd does transmit through seeds in hop plants at a rate of around 8%.7 Preliminary studies performed by TUMI Genomics in collaboration with EZ-genetics suggest cannabis seed transmission does occur at variable rates depending on strain and level of infection of the parent plants.

Water Transmission: It has also been observed that viroids are in high concentration in the roots8 and can move from the root into runoff water.9 Plants sharing a common water source with infected plants, such as recirculating water systems or flood and drain procedures, are at risk for transmission of the viroid.

Insect and Other Vector Transmission: The jury is still out as to whether or not insects can transmit HLVd. However, multiple viroids are transmitted via insects, so it is likely that HLVd insect transmission occurs. Recent studies also indicate that fungal pathogens, like Fusarium, can transmit viroid infections.6 While pathogenic fungus is a major concern for cannabis growers in its own right, limiting the prevalence and spread of fungal pathogens in your facility could help limit hop latent viroid transmission as well.

Therefore, implementing proper sanitation practices and limiting pest access can help minimize transmission risks.

Preventive Measures

Prevention plays a vital role in safeguarding cannabis crops against HLVd. The STOP program, developed by TUMI Genomics, offers a comprehensive approach that includes maintaining a Sterile environment, Testing mother plants regularly, Organizing the facility to minimize pathogen spread, and Protecting the facility’s borders from introduction of infected plant material, insects and contaminated water. More details on these preventative measures can be found here.

Pathogen Diagnostics

Protecting your plants from hop latent viroid requires accurate identification and removal of infected plants before the infection spreads to other plants. To accomplish this, several critical factors should be considered:

Type of test: HLVd and all viroids can only be detected by a molecular test (a test that detects the presence of DNA/RNA). Among common molecular tests, PCR is generally the most sensitive and accurate method. PCR can provide both a diagnosis and an approximate viroid level, allowing informed management decisions. Other types of molecular tests, such as LAMP and RPA, can formally be as sensitive as PCR, but the classic versions of these assays often suffer from false positive/negative results, reducing accuracy.

Figure 3: HLVd Levels and Distribution

Tissue type: An important consideration for HLVd detection is the plant tissue selected for testing, especially when identifying low-level or early infections when HLVd is not yet systemic. Studies completed by TUMI Genomics and others show root tissue contains the highest levels of HLVd and is the most reliable tissue for detection of viroid infection. While upper root tissue appears to contain the highest levels of viroid, roots from anywhere in the root ball are predictive of infection. Samples taken from the leaves/foliage tend to have lower levels of viroid and may produce false negative results.

Figure 4: Testing Schedule

Testing frequency: Routine pathogen testing is standard practice in general agriculture and is critical to maintain a healthy cannabis crop. Testing of mother plants every 4-6 weeks for economically critical pathogens (such as HLVd) will help ensure a successful run and a high-quality product.

Disinfection Methods

Studies have shown that viroids can remain infectious for longer than 24 hours on most common surfaces11 and 7 weeks in water.10 Making effective disinfection methods essential to limit the spread of HLVd. While common disinfectants like alcohol and hydrogen peroxide are ineffective against viroids, a 10% bleach solution has shown efficacy in destroying HLVd. Proper tool sterilization practices, such as soaking tools in bleach for 60 seconds, are crucial to prevent transmission during plant handling.

Figure 5: Bleach Dilution

Hop latent viroid poses a significant threat to the cannabis industry, leading to substantial economic losses. Timely and accurate pathogen diagnostics, along with stringent preventive measures, are essential for minimizing the impact of HLVd. Regular testing, proper disinfection protocols and adherence to pathogen prevention programs can help ensure the health and vitality of cannabis crops in the face of this global pandemic.

Cannabis Seeds: The Fundamental Building Blocks of the Thriving Regulated Industry

By Landra DeLoach
1 Comment

Spring is a time of renewal, growth and planting. While many gardeners focus on traditional crops, there is a growing community of cannabis enthusiasts who are also embracing the opportunity to cultivate their own cannabis plants.

Research from New Frontier Data reveals that approximately 3 million people worldwide grow their own cannabis at home, resulting in a staggering yield of approximately 11 million pounds of smokeable flower each year. This number is projected to reach 15 million pounds annually by 2030. Amidst all the excitement around planting and growing, it is essential not to overlook the indispensable foundation of all cannabis plants: the seeds.

The Power of Cannabis Seeds

Affordable and versatile, cannabis seeds provide growers with the ability to cultivate specific strains tailored to their health and wellness needs. These seeds are typically the size of a peppercorn, characterized by an ovular shape tapering to a pointed end. While seeds can vary in color and striation, they typically exhibit a brown hue. Unfertilized seeds, on the other hand, appear off-white and are considerably smaller in size.

Economic Impact

These tiny powerhouses enable growers to cultivate customized strains, while also contributing to the economic growth of the global seed market.

The global cannabis seeds industry was valued at $1.3 billion in 2021, according to Allied Market Research. Experts predict that this figure will surge to $6.5 billion by 2031. Notably, North America accounted for more than 80 percent of the global seed market in 2021.

Benefits for Home Growers

According to New Frontier Data, 70 percent of home growers purchase seeds and cultivate cannabis for the sheer enjoyment of the process while 52 percent find it to be a convenient option. In addition to these advantages, numerous research studies highlight the multiple health benefits of growing one’s own crops, including reduced stress levels, decreased anxiety and increased exposure to the outdoors. Some innovative chefs have even begun incorporating cannabis seeds into their culinary creations, further expanding the versatility and appeal of these seeds.

Seed Safety Considerations

Given that cannabis seeds form the foundation of the entire cannabis industry, it is crucial to understand the various options for obtaining them. One increasingly popular method is through online seed banks, such as Rocket Seeds. However, it is important for those new to purchasing seeds online to thoroughly research the legalities surrounding these transactions. Cannabis seeds are subject to legislation similar to other cannabis products such as flower, concentrates and edibles. The legality of purchasing seeds varies depending on the state in which one resides. It is vital to check local legislation before making any decisions. In states where adult use cannabis is legal, buyers only need to be 21 years or older to order seeds online. Conversely, in states where adult or medicinal use is not permitted, purchasing seeds online remains completely illegal.

Purchasing Seeds Online

Selecting a reputable online seed bank is critical. Ensure that the chosen seed bank has positive customer reviews, offers quality customer service and provides germination guarantees. Researching the available strains, payment options and shipping policies is also essential. It is advisable for beginners to start small by purchasing only a few seeds at a time. Prior to planting, conducting thorough research is necessary, as there are numerous variables to consider and a steep learning curve to navigate. Fortunately, abundant resources are available to assist in this journey. For example, we offer valuable advice on getting started. Additionally, individual seed manufacturers, as well as online resources and apps like Seedtracker, provide guidance and support.

Continued Growth

The U.S. legal cannabis market is projected to exceed $31.8 billion in annual sales by the end of 2023, according to leading cannabis research firm Brightfield Group. Furthermore, they anticipate that within five years, the market will surpass $50 billion in annual sales. Amidst this flourishing industry, it is important to recognize that seeds form the backbone of this expansive market.

As the cannabis industry continues to thrive and expand, it is crucial to acknowledge the fundamental role played by seeds. These tiny powerhouses enable growers to cultivate customized strains, while also contributing to the economic growth of the global seed market. By recognizing the benefits of growing one’s own cannabis and taking proper precautions when purchasing seeds, individuals can partake in this exciting and rapidly growing industry while savoring the rewards of their own harvests.

The 3-Legged Stool of Successful Grow Operations: Climate, Cultivation & Genetics – Part 5

By Phil Gibson
No Comments

This is Part 5 in The 3-Legged Stool of Successful Grow Operations series. Click here to see Part 1, here to see Part 2,  here to see Part 3, and here to see part 4. Stay tuned for the final piece in the series, Part 6, coming in the new year.

Genetics

With climate and cultivation methods explored, today, we cover the third leg in the primary stool, genetics. Some would say good genetics is all that you need and anyone can be successful with good genetics. We all know that this is not experience talking. Things can go wrong, even with great genetics. Here are some inputs how to pick great genetics so you have them on your side.

Hybrids & Strains

Seeds, the beginning of genetic performance

Everything successful cultivators grow is aligned to their consumer audience. This is hard to predict as the desires in your market will migrate over time as one variety will be highly popular and poof, it’s not, so constant change is necessary. Finding the right flower at the right time is the trick.

The first thing to decide in your pursuit of the ideal phenotype (or pheno-hunt) are your target customers. Assuming you’ve made the choice to go “top-shelf” for aeroponic or hydroponic flower, your variety selection comes down to filial breeder seeds or stable strains from suppliers you know.

Filial hybrids are developed by professional breeders. Two distinct inbred strains are repetitively crossed until their traits are highly consistent. At this point, these carefully inbred lines are crossed to selectively mix the two well defined sets of traits. Filial hybrids are stable and you can usually rely on the robust nature of these seeds.

Strains, on the other hand, are the cross of two strains but they may not be inbred stable filial strains. Sometimes this results in something amazing, but just as randomly, the traits can morph into something disappointing.

Our advice here is to pay the premium and start with high quality reliable stock.

Uniformity

Consistency? Will you grow one variety or multiple varieties per room and per harvest; will they grow well together? Do they grow and test out in a consistent manner (plant size, color, bud size & yield, tested terpene profiles, aroma, disease resistance or tolerance). Are you growing for top shelf flower or bulk extraction? I will focus this discussion on top shelf flower. Premium seeds from professional filial hybrids are not a guarantee, but they are designed to be stable and consistent in their growth and results targeting high performance.

High cannabinoids: 420Kingdom Grapes & Cream

Here, experience counts and reliable seed vendors tend to be well established with filial lines that are worth the investment. Once you acquire your genetics, how to leverage that investment?

Killer Genetics

What traits does your consumer want? Initial searches usually target THC or CBD levels and they evolve to special terpene profiles or pleasing aromas. Flower or bud shape, color, size, density, and stickiness are also traits that can differentiate your genetics. As a producer, you also want to target yield including tall or stretching genetics, or short and fast flowering, germination rates (sometimes they don’t) and percentage of likely hermaphroditing (seldom zero). The qualitative aspects (smoking characteristics) of your production flower that deliver a unique customer experience, both real and imagined, wrap up your brand experience.

So, as you can guess, one size does not fit all types of consumers. Very high yielders that are immediately targeted for extraction offer very different values than perhaps a smaller yielding very potent top shelf smokeable bud. It is a good strategy to plan for a handful of strains that you can bring to market so you have something that will hit the sweet-spot when you deliver your harvests.

Seeds

Seeds with documented guarantees from reliable sources eliminate the characteristic risk, and with the right testing reports, they guarantee no pathogens as well.

The challenge of seeds can be genetic variation, as discussed above, depending on the stability of the commercial breeder. This potential variance can lead to surprises and disappointment. Starting from seed also takes more time to germinate the seeds, exterminate the males, grow mother plants, take cuttings, and start the cycle. This can add 12-16 weeks to your go-green targets for your flower rooms. Be sure to integrate this cycle time planning into your production cycle.

Clones

Insourced clones are the fastest way to go green and move through veg to produce flowering plants and bud harvest. Clones are created by taking a branch cutting from a “mother” plant and typically “rooting” that cutting using an aeroponic cloning system. This clone process can take a few days or weeks depending on the grow environment and aeroponics process. A rooted clone maintains the genetic characteristics and phenotype of the mother plant.

The typical way smaller grow shops get started is through buying clones that are made from these rooted branch cuttings. The combination of mother plants, clones, and sometimes “veg” plants are gathered together in a “nursery”. Nurseries need to be stable for long periods of time to produce the veg growth necessary for cuttings. This time delay makes it harder for the nursery provider to keep the area sterile, without disease, and without pests. If the mothers carry a disease, they are likely to transfer that biologic over to the cuttings. If the media that the clones are grown in picks up root gnats, they will travel with the clones into your facility. The short answer is source your clones from professionally run operations. This trust is worth every penny.

Blue Dream clone array: AEssenseGrows

Insourcing clones allows you to avoid the cost and complexity of running a “nursery”, but this also moves the pest management and quality of mother stock and clones outside of your control zone. In other words, you depend on the clone supplier for both healthy plants AND availability. No clone available from your supplier means no flower in your grow rooms. Your production revenue depends on the reliability of your clone supplier in many ways.

In some grow operations, the nursery is extended to cover the vegetative growth stage of cannabis plants or “veg.” In other approaches, a flower room is occupied for an additional week or two for veg growth. We at AEssenseGrows are strong advocates of running all cloning and vegging activity in a vertical aeroponic nursery in parallel to your flower rooms

Mothers, clone, and veg stages all grow with a vegetative growth light schedule (18 hours on, 6 hours off). The typical process is to take a cutting from a mother plant, place that in an aeroponic “cloner” for 10-12 days until a healthy set of roots is formed for the cutting. That clone is then typically pinched off at the top of the plant at which point the veg stage can begin. Light intensity is gradually increased and the plants are typically vegged for an additional 2 weeks, at this point, you have a bushy veg plant that is ready for a 12/12 light cycle and flowering.

In aeroponics, all of this is done in nursery space. If you choose to use soil or grow media approaches, a series of increasingly larger buckets or rockwool cubes are needed to manage the veg stage and the transition to flower. This can be done in a dedicated veg room or for the first week or two in the flower rooms

Tissue Culture

Healthy Agent Orange mothers: Onyx

Another method for creating your young plants is tissue culture. This is the method of harvesting genetic material from an existing plant with desired characteristics. These genetic samples can be contamination free and even supplied by a genetic bank. A portion of these tissues are cultured in a gel grow tray and the plant will develop roots with a stalk that reaches upward for light energy.

These plant starts are hardened in a similar method to cloning and typically, these starts are grown into mothers that supply your cuttings for the clone cycle. This is an advanced method, so plan for research and development with expected delays to the front end of your sourcing cycle if you choose this path.

Strain Examples

Selecting the best genetics for your market is an art form. Many choices abound. High yielding dense classic strains are Blue Dream, Skittles, Sour Diesel and Girl Scout Cookies. Each of these deliver a typical 18%-24% THC content from fast growing, medium height high plants that yield dense buds. Very potent THC genetics that are popular currently are various “OG” genetics, Bruce Banner, various “Cake” genetics and Kush options. Variants of these run from 25% to 35% THC content.

This Chapter’s Hero Award

Every customer produces great results for their markets but we are very impressed by the genetic selections by 420Kingdom in the central valley of California. Jeffrey Thorn is the owner there and continues to impress with a range of high potency genetics that demand premium prices and sell out regularly in their highly competitive market.

With good genetics for your consumers, you are positioned to be successful. Advanced cultivation methods like aeroponics and hydroponics can give you a lift and the right environment and nutrition helps you tie this all together. Our next and last chapter will cover consistency and repeatability through Standard Operating Procedures (SOPs).

Tissue Culture Cultivation Can Transform the Way We Grow Cannabis

By Max Jones, Dasya Petranova
1 Comment

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.

Defining Hemp: Classifications, Policies & Markets, Part 2

By Darwin Millard

In Part 1 of this series we answered the question: What is “hemp”; and addressed some of the consequences of defining “hemp” as a thing. In Part 2, I will explore this topic in more detail and provide some commonsense definitions for several traditional hemp products based on a classification approach rather than separating “cannabis” from “hemp”.

Classifications, Specifications, and Test Methods – Establishing Market Protections for Hemp Products Through Standardization

Does making a distinction between “hemp” and “cannabis” make it easier to protect the interests of the seed and fiber markets?

On the face of it, this question seems obvious. Yes, it does.

Up to this point in history, the bifurcation of the cannabis plant into resin types and non-resin types has served to provide protections for the seed and fiber markets by making it easier for producers to operate, since the resins (the scary cannabinoids, namely d9-THC) were not involved. Today, however, the line in the sand, has been washed away, and “hemp” no longer only refers to non-resin producing varieties of the cannabis plant.

The structure of cannabidiol (CBD), one of 400 active compounds found in cannabis.

As more and more hemp marketplaces come online with varying limits for d9-THC the need for standardization becomes even more pressing. Without standardization, each marketplace will have its own requirements, forcing businesses looking to sell their products in multiple jurisdictions to comply with each region’s mandates and adds a significant level of burden to their operations.

Providing an internationally harmonized definition for hemp is an important first step but allowing the d9-THC limit to vary from jurisdiction to jurisdiction has some unintended (or intended) consequences (#NewReeferMadness). These discrepancies between legal marketplaces will inevitably lead to the establishment of global trade regions; where, if your product cannot meet the definition of “hemp” in that region, then you could effectively be barred from participating in it.

A process which has already started. Harmonizing around 0.3% is great for the US, Canada, and European Union, but what about other stakeholders outside of these markets?

And, at what point does the conflict of hemp from one region with a d9-THC content of 0.3% and hemp from another region with a d9-THC content of 1% being sold into the same market become a problem?

Perhaps a better long-term solution for protecting the market interests of “hemp product” stakeholders would be to establish specifications, such as identity metrics, total cannabinoid content, especially d9-THC, and other quality attributes which have to be verified using test methods for a product to be classified as “hemp”. This system of standards (classifications, specifications, and test methods) would allow for more innovation and make it significantly easier for cannabis raw materials that meet these specifications to find a use rather than being sent to the landfill. Bolstering advancements and opening the door for more market acceptance of the cannabis plant, its parts, and products.

An Alternative Approach to Defining Hemp

Below are some proposed definitions related to common terminology used in the hemp marketplace based on the concept that there are no hemp plants, there are only cannabis plants that can be classified as hemp, and hemp products are simply cannabis products that meet certain specifications to allow them to be classified and represented as hemp.

  • Hemp, n—commercial name given to a cannabis plant, its parts, and products derived therefrom with a total d9-THC content no more than the maximum allowable limit for the item in question. (Maybe not the best definition, but it makes it clear that not only does the limit for d9-THC vary from jurisdiction to jurisdiction it varies from product type to product type as well.)
  • Hemp flower, n—commercial name for the inflorescence of a cannabis plant that can be classified as hemp.
  • Hemp seed, n—commercial name for the seeds of a cannabis plant which are intended to be used to grow another cannabis plant that can be classified as hemp.
  • Hempseed, n—commercial name for the seeds of a cannabis plant which are intended to be used as food or as an ingredient in food.
  • Hemp seed oil, n—commercial name for the oils expressed from the seeds of a cannabis plant.
  • Hemp seed cake, n—commercial name for the solid material byproduct generated during the expression of the oil from the seeds of a cannabis plant.
  • Hemp flour/meal/dietary-fiber, n—commercial name for the powdered seed cake of a cannabis plant intended to be used as a food or as an ingredient in food with a protein content no more than 35% by weight.
  • Hemp protein powder, n—commercial name for the powdered seed cake of a cannabis plant intended to be used as a food or as an ingredient in food with a protein content between 35% and 80% by weight.
  • Hemp protein isolate, n—commercial name for the powdered seed cake of a cannabis plant intended to be used as a food or as an ingredient in food with a protein content above 80% by weight.
  • Hemp fiber, n—commercial name for the cellulosic-based natural fibers of a cannabis plant.
  • Hemp shives, n—commercial name for the hurd of a cannabis plant which have been processed to defined specifications.
  • Hempcrete, n—commercial name for a solid amalgamation of various aggregates and binders, typically comprised of the hurd (shives) of a cannabis plant and lime.

The d9-THC limits for each product were purposefully omitted because these specifications still need to be defined for each product type. Leaving the d9-THC limit up to each authority having jurisdiction, however, is not the answer. It is fine if you comply with a lower d9-THC limit and want to sell into a market with a higher d9-THC limit, but what do you do if you are above the limit for the market you want to sell into? For now, you lose out on potential revenue.

Hemp-derived CBD extract

I am not advocating that everyone starts selling “hemp” as “cannabis,” or vice versa, far from it. I am advocating for a more commonsense and inclusive approach to the marketplace though. One that would allow for the commercialization of materials that would normally be going to waste.

To me it is simply logical. There are no hemp plants, there are only cannabis plants that can be classified as hemp. There are no hemp products, there are only cannabis products that can be classified as hemp. In order for a cannabis product to be marketed, labeled, and sold as a hemp product, i.e. to be classified as a hemp, it would need to meet a set of specifications and be verified using a set of test methods first. But fundamentally the product would be a cannabis product being certified as “hemp”. And that is the shift in thinking that I am trying to get across.

Exclusionary Actions – Disenfranchising Stakeholders

The cannabis plant is an amazing plant and to fully capitalize on the potential of this crop we have to start allowing for the commercialization of cannabis raw materials that are not controlled by the UN Single Conventions, i.e. the seeds, stalks, roots, and leaves when not accompanied by the fruiting tops or the resin glands. Not to do so disenfranchises a significant number of stakeholders from participating in established legal avenues of trade for these goods. A concept proposed and endorsed the ASTM D37 in the published standard D8245-19: Guide for Disposal of Resin-Containing Cannabis Raw Materials and Downstream Products.

If you are stakeholder in the hemp marketplace, you may feel threatened by the idea of the market getting flooded with material, but how are the demands of the so called “green economy” going to be met without access to more supply? Organic hemp seed for food production is scarce but there is plenty of conventional hemp seed for the current demand, but what happens when hempmilk is positioned to displace soymilk in every major grocery store? To feed the growth of the human population and allow for a transition to a truly “green economy,” we need to ensure that the policies that we are putting in place are not excluding those looking to participate in the industry and disenfranchising stakeholders from burgeoning marketplaces, nor alienating a segment of the marketplace simply because their plant cannot be classified as “hemp”.

Until next time…

Live long and process.

Defining Hemp: Classifications, Policies & Markets, Part 1

By Darwin Millard

What is “hemp”?

The word “hemp” has many meanings. Historically the term has been used as the common name for the Cannabis sativa L. plant. Just like other plants, the cannabis plant has two names, a common name, hemp, and a scientific name, Cannabis sativa L. After the ratification of the UN Single Conventions on Narcotic Drugs and Psychotropic Substances, in 1961 and 1972 respectively, the term started to be used to distinguish between resin producing varieties of the cannabis plant and non-resin producing varieties of the cannabis plant. Nowadays the term is generally used to refer to cannabis plants with a delta-9-tetrahydrocannabinol (d9-THC), a controlled substance, content equal to or less than the maximum allowable limit defined by each marketplace.

Tetrahydrocannabinol (THC), just one of hundreds of cannabinoids found in cannabis.

In the United States and Canada, the limit is defined as 0.3% on a dry weight bases, and until November 2020, in the European Union, the limit was defined as 0.2%. After years of effort the “hemp” industry in Europe was successfully able to get the limit raised to 0.3% to be in line with the United States and Canada – creating the largest global trade region for hemp products. But there exist several marketplaces around the world where, either through the consequences of geographic location or more progressive regulations, the d9-THC content in the plant can be substantially higher than 0.3% and still considered “hemp” by the local authority.

To address these variances, ASTM International’s Technical Committee D37 on Cannabis has been working on a harmonized definition of hemp, or industrial hemp, depending on the authority having jurisdiction, through the efforts of its Subcommittee D37.07 on Industrial Hemp. The following is a proposed working definition:

hemp, n—a Cannabis sativa L. plant, or any part of that plant, in which the concentration of total delta-9 THC in the fruiting tops is equal to or less than the regulated maximum level as established by an authority having jurisdiction.

Discussion: The term “Industrial Hemp” is synonymous with “Hemp”.

Note: Total delta-9 THC is calculated as Δ⁹-tetrahydrocannabinol (delta-9 THC) + (0.877 x Δ⁹-tetrahydrocannabinolic acid).

This definition goes a long way to harmonize the various definitions of hemp from around the world, but it also defines “hemp” as a thing rather than as a classification for a type of cannabis plant or cannabis product. This is a concept rooted in the regulatory consequences of the UN Single Conventions, and one I strongly disagree with.

The definition also leaves the total d9-THC limit open-ended rather than establishing a specified limit. An issue I will address further in this series.

Can “hemp products” only come from “hemp plants”?

If you are an invested stakeholder in the traditional “hemp” marketplace, you would say, yes.

But are there such things as “hemp plants” or are there only cannabis plants that can be classified as “hemp”? (The definition for hemp clearly states that it is a cannabis plant…)

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

There is no distinction between the cannabinoids, seeds, and fibers derived from a cannabis plant that can be classified as “hemp” and those derived from a cannabis plant that cannot. The only difference is the word: “cannabis,” and the slew of negative connotations that come along with it. (Negative connotations that continue to be propagated subconsciously, or consciously, whenever someone says the “hemp plant” has 50,000+ uses, and counting, and will save the world because it’s so green and awesome, but not the “cannabis plant”, no that’s evil and bad, stay away! #NewReeferMadness)

The declaration that “hemp products” only come from “hemp plants” has some major implications. “Hemp seeds” can only come from “hemp plants”. “Hemp seed oils” can only come from “hemp seeds”. “Hemp fibers” can only come from “hemp plants”. Etc.

What does that really mean? What are the real-world impacts of this line of thinking?

Flat out it means that if you are growing a cannabis plant with a d9-THC content above the limit for that plant or its parts to be classified as “hemp”, then the entire crop is subjected to the same rules as d9-THC itself and considered a controlled substance. This means that literal tons of usable material with no resin content whatsoever are destroyed annually rather than being utilized in a commercial application simply because a part or parts of the plant they came from did not meet the d9-THC limit.

Some of the many products on the market today derived from hemp

It is well known that d9-THC content is concentrated in the glandular trichomes (resin glands) which are themselves concentrated to the fruiting tops of the plant. Once the leaves, seeds, stalks, stems, roots, etc. have been separated from the fruiting tops and/or the resin glands, then as long as these materials meet the authority having jurisdiction’s specifications for “hemp” there should be no reason why these materials could not be marketed and sold as “hemp”.

There are several reasons why a classification approach to “hemp plants” and “hemp products” makes more long-term sense than a bifurcation of the “cannabis” and “hemp” marketplaces, namely from a sustainability aspect, but also to aid in eliminating the frankly unwarranted stigma associated with the cannabis plant. #NewReeferMadness

That said, say you are a producer making shives from the stalks of cannabis plants that can be classified as “hemp” and then all of a sudden, the market opens up and tons of material from cannabis plants that cannot be classified as “hemp,” that was being sent to the landfill, become available for making shives. Would you be happy about this development? Or would you fight tooth and nail to prevent it from happening?

In this segment, we looked at the history of the term “hemp” and some of the consequences from drawing a line in the sand between “cannabis” and “hemp”. I dive deeper into this topic and provide some commonsense definitions for several traditional hemp products in Part 2 of Defining Hemp: Classifications, Policies & Markets.

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

By Aaron Green
No Comments

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

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

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

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

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

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

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

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

Bill Conkling, Founder and CEO of Maggie’s Farm

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

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

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

Aaron: How do you define local?

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

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

Aaron: What states are those specifically?

Bill: I think Colorado and New Mexico, primarily.

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

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

Aaron: So Colorado state only right now?

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

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

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

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

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

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

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

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

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

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

Bill: We do not.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Aaron: Do you do fresh frozen?

Bill: We do some, yes.

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

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

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

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

Aaron: How many acres do you have?

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

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

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

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

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

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

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

Aaron: That concludes the interview, thank you Bill!
