Leaders in Infused Products Manufacturing: Part 1

By Aaron Green
No Comments

Cannabis infused products manufacturing is quickly becoming a massive new market. With companies producing everything from gummies to lotions, there is a lot of room for growth as consumer data is showing a larger shift away from smokable products to ingestible or infused products.

This is the first article in a series where we interview leaders in the national infused products market. In this first piece, we talk with Keith Cich, co-founder of Sunderstorm, Inc. and the brand Kanha Gummies. Keith and his business partner, Cameron Clarke, started Kanha Gummies in 2015 after long careers outside of the cannabis industry. In 2015, they went all in and started the brand, which grew to be a major player and driving force in the California market.

Next week, we’ll sit down with Mike Hennesy, director of innovation at Wana Brands. Stay tuned for more!

Aaron Green: Keith, nice to meet you. Thank you for taking the time today. Tell me about how you got Sunderstorm off the ground and how you got involved in the company?

Keith Cich: Absolutely. So, my business partner, Cameron Clarke, is a lifelong friend. We met as undergraduates at Stanford University. I went on to work on Wall Street and did commercial real estate. Cameron has been a serial entrepreneur, from a much more technical side working in software. He was actually one of the first people to bring the Açai Berry to market and put it on the shelves of Whole Foods. So, he’s kind of the science and operations guy and I’m the finance and business guy.  It’s been very synergistic.

Keith Cich, co-founder of Sunderstorm, Inc.

By 2015 we had both traveled extensively and were big advocates of plant medicine and cannabis as another form of plant medicine. We also have a 15-year track record of going to Burning Man together. Really, explorations in consciousness and plant medicine were what tied us together. When cannabis came up as a business opportunity, we just kind of looked at each other and said, you know, we have a lot of business experience to bring to the table. We have a love of the plant and an appreciation for how it will impact society. So, we kind of went all in in 2015 under proposition D, and set up operations in Los Angeles at that time.

Aaron: How did you decide to get into infused products from the list of choices?

Keith: Yeah, we initially set up extraction, but we felt that cultivation and extraction would ultimately be commodities.  However, if you could develop popular brands you could carve out valuable shelf space and have longevity.

We acquired a small gummy company in February 2016. In the beginning of it all – I call it “Cannabis 1.0.” At that time, a lot of the packaging was really oriented around men in their 20s focused on “high consumption.” The packaging was a lot of black and skull and crossbones, and it didn’t really represent who Cameron and I were as people. You know, we were a little bit older and well-traveled. And we just felt like when adult use would come in that brands would take a different pathway. So, we hired a branding person to come in and help with packaging.

We really focused on a product that would appeal to females because it was clear they were going to be 50% of the market – and packaging that would really appeal to older people, which we thought would come on board once the stigma of cannabis was reduced. And so, we really set up Kanha gummies, at that time in early 2016, to be this adult use product that would appeal to a wide spectrum, both medical users as well as adult users in the time that would come in the not too distant future.

Aaron: Yeah, that’s interesting. You talked about how you thought about differentiating in the early days getting off the ground. How do you think about differentiating today?

Keith: The two things that really set Sunderstorm apart from the crowd is automation and innovation. We were the first gummy company to invest hundreds of thousands in European confectionery equipment, which allowed us to scale our business, but more importantly, produce an identical product every time. The reason we hear people come back to Kanha gummies is that they have the same replicable experience every time, which is really the key to CPG companies. So, it’s really stringent automation that allowed us to develop precise dosing. In fact, in 2019, we won the award from CannaSafe, which is the largest lab in California, for the most accurately formulated edible. We dialed in manufacturing and that’s what set us apart in the early years.

My partner is really geared towards science and implementing new delivery systems for cannabinoid products. We were the first company to come out with a nano edible about a year ago in 2019 and we are still the leader in offering consumers nano-molecular delivery systems. What does that mean? One of the common problems with edibles is that it takes 45 minutes to an hour for it to kick in. We all know friends who take a cookie and double up on the cookie and end up having too big of an experience. Rapid onset curbs that risk. Our nano gummy kicks in about 15 to 20 minutes, and it’s got just this really nice journey to it. We’ve separated the audience between the people that have our classic gummies, which takes longer to kick in, maybe a little bit stronger and the nano technology, which has a really fast onset, and really kind of a discrete journey. We stay ahead of the competition today, because of the nanotechnology that we’ve implemented in gummies.

As I always say, it’s not about how much vitamin C you take – it’s more about how much vitamin C gets in your blood stream. And it’s the same with cannabis, right? It’s how much THC and CBD or other molecules get in your system. So it’s about really having the highest bioavailability and the best performing products. And that’s what our customers have come to believe about Sunderstorm.

Aaron: You’ve talked about a couple new products from Kanha. At a high level, can you talk about your process for ideating and creating a new product?

Keith: Sure. I could use an example of a product that we’ve just kind of relaunched. It’s called the Tranquility gummy and it’s targeted for sleep. What we’ve discovered is there’s a whole host of medical reasons why people take cannabis – as well as the adults who take cannabis for entertainment – but sleep is a major issue for Americans of all ages. It’s surprising. It impacts 20 year olds and it impacts 60 year olds.

Part of the process of coming up with a product is trying to figure out what’s the need in the marketplace. So in this case, we really looked and said, hey, let’s target sleep and see if we can experiment and come up with a product. Our first round of Tranquility had a mix of CBD and THC in it because both of those are valuable for sleep. CBD is a chill-pill that kind of makes you calm so you can go to sleep. THC is often something that helps people stay asleep.

“We go through many iterations of a product before it actually hits the marketplace.”In that product, we also added 5-HTP, which is a serotonin booster, which once again, people take when they have anxiety or stress. So it’s kind of a stress reliever, and it helps you be calm, which again, I think a lot of the problems for people who have an issue with going to sleep, it’s having so much on their mind that they can’t stop the monkey mind to actually enter into sleep to begin with.

We also added just a small amount, one milligram, of melatonin. We know that Melatonin is a sleep aid, but you don’t want to take so much melatonin that your body stops producing melatonin because you’re taking the supplements. So at the end of the day, you want to just encourage and coax your body into healing and not overkill it with a pharmaceutical. Right?

So that was our first generation and we worked with that but my partner looks through a lot of research that’s occurring on different cannabinoid particles, and it became clear that CBN, which is kind of a new cannabinoid that’s hitting the press, actually had really strong properties for sedation and keeping people asleep. So, we added the largest dose of CBN in any gummy, and then re-launched that product a month or two ago. And we’re getting incredible feedback from shops that they’re selling out. It’s awesome, because people are actually taking the gummy and having the effect of falling asleep and staying asleep.

It’s the combination of the different factors. No one factor is so overwhelming like a pharmaceutical drug. But it’s the combination of the different factors together that make for a great product. And we fortunately have dozens of people in our company who are happy to do R&D for our new products. We also have some people outside the company that are consultants and experts as well. We go through many iterations of a product before it actually hits the marketplace. And that’s the second thing: it’s a lot of rigorous R&D testing of products before we launch it for the end consumer.

Aaron: Yeah, so if we can touch on that, can you tell me about your experience with your most recent product launch? Whether it’s the NANO5 or the Tranquility gummies? How did you think about preparing the market for the launch? Preparing your team for the launch? And then how did it go?

Keith: I’ll talk about our sublingual line called NANO5. Again, it’s a nano product where every molecule of CBD or THC is wrapped in a molecule of fatty lipids, so that when you spray it on your tongue, it tricks your body into absorbing it directly into the bloodstream and doesn’t actually go through the digestive tract and the liver. The bioavailability of these sublinguals is high and 70 to 80% of the cannabinoids actually get into your bloodstream.

We’ve done blood sampling tests versus your standard tincture. Your standard tincture is just MCT oil and cannabis, it’s pretty crude, kind of caveman-ish, quite frankly, when compared to the delivery of pharmaceuticals are today. NANO5 is a much more advanced delivery system.“We’re here to really try to educate people the best that we can.”

Now we have the product… right? This is a sophisticated product that’s challenging for bud tenders to explain when consumers come in with their medical needs. We had to create a lot of written brochures about how the product works, what the dosages are and that sort of stuff. Then our sales people go in and actually train the shops. They’ll pull bud tenders out and do training sessions and talk about NANO5, what makes it different from other tinctures, what medical conditions is it good for, etc. It’s kind of old fashioned, in-store training.

Then we finally have implemented a new piece, which is digital bud tender and consumer training. We are leveraging a platform for bud tender training, we talk with the shop, talk about the product and if the shop manager agrees we send a link out to all the bud tenders who take a quiz. The bud tenders get educated on an online platform, take a quiz, and then when they pass the quiz, they get a licensed sample of the product to try themselves so they have firsthand experience.

What we find in many shops is that the consumer is still not that educated about cannabis, particularly for medical uses, and particularly what I call the “new consumer” that hadn’t used cannabis in their lives, because it had such a high stigma to it and now with the reduction of the stigma it means a 40 or 50 year old woman might go into a store to find something to help with pain, or help with anxiety. Now, the bud tender can use the training that they’ve learned on NANO5, and understand that this could be a good product for them, and then talk about it intelligently and give some materials to the consumer before they walk away.

It can be intimidating for consumers to go into a shop, you know, it’s a new experience. It’s like going to the doctor’s office, you don’t always hear what they say, because you’re kind of nervous. So giving them the written materials, and even a test to follow up on online really allows for a form of education that is in tune with the user needing to learn at their own speed and really to just take away what’s important for them.

Aaron: Did I hear you correctly? The user – the end consumer – can also do a quiz?

Keith: Yes. Sunderstorm is about science and education. There’s a lot of assumptions in the marketplace that may not be correct. So, we’re here to really try to educate people the best that we can. And we really believe the rest of the world acts in a digital manner for education. In some ways, cannabis is a little bit behind the times because it’s difficult to advertise on Facebook and traditional venues. So we have one hand tied behind our back when we’re dealing with the digital world. But we at Sunderstorm are big believers that digital will be the way that cannabis consumers learn about brands, learn about products and learn about cannabinoids, and we want to be at the forefront of that education process.

Aaron: OK, we talked about some challenges. One of the challenges I hear a lot is about sourcing ingredients for infused products. How do you go about sourcing ingredients in your infused product lines?

Keith: Our primary ingredient that we source is distillate. And starting back in prop 215 days, we have a zero parts per billion policy on pesticides. What we discovered is before lab testing and licensure came in place is that 80 to 90% of the oil out there actually had pesticide levels that were way beyond safe. It really took licensing and the implementation of lab testing to change that regime. We now buy distillate from third party extractors and we have a handful of really big, really solid players onboard who provide that oil to us. The key is that if there’s any detectable trace of pesticides, we send it back and they replace it with a not-detect batch. So for us, that’s really the key to the whole supply chain: starting with oil that’s clean and really good quality.“Delivering the product in a compliant manner has been one of our logistical challenges, but one that I think we’ve done quite well at day in and day out.”

Fortunately, we’re one of the bigger brands in the industry so we have a little clout to make sure that the people that give us our oil are giving us their top shelf, and not their bottom shelf. We then have also made it a point to use only natural flavoring and natural coloring in our gummies. Believe it or not some of the red coloring actually is derived from beets and beet juice. We use spirulina as a source for our blue green colors. All of the gummies that we produce, not only have no pesticides, but they have no artificial flavors and no artificial coloring, which is of course standard in mainstream gummies that you buy at CVS or the local drugstore. So we really feel like we want to put out a healthy product and Cameron and I always look at each other, like, ‘we wouldn’t sell a product that we wouldn’t put into our own bodies.” And we’re very health conscious, you know, buying organic produce and not wanting pesticides to be inside us.

Aaron: Can you give me an example of a challenge you run into frequently, and this could be a business challenge, a marketing challenge, financials… something that you run into frequently?

Keith: Yeah, so we not only manufacture our products in California, but we also do self-distribution to over 500 retailers, meaning in store dispensaries and delivery services throughout California. With these 500 customers, we have two distribution points, one in LA and one in the Bay Area where I’m located. It’s an amazing challenge logistically. Not only are we running a manufacturing operation that requires precision – and it’s highly regulated – but we run a distribution company that’s highly regulated. For us the challenge is how do we efficiently deliver product to the Oregon border when we’re manufacturing in LA? We’ve had to spend a lot of time developing protocols for logistics and distribution to be able to basically meet demand throughout the state. And we’ve been growing like crazy. We add 10 new shops probably every week.

Delivering the product in a compliant manner has been one of our logistical challenges, but one that I think we’ve done quite well at day in and day out.

Aaron: What kind of trends are you looking at in the industry? And what keeps you excited?

Keith: I think COVID-19 has touched every aspect of our lives and it is impacting how we consume cannabis. Because it’s a respiratory disease, I think people have been wanting to shy away from smoking flower or vaping to keep their lungs healthy as a precaution in case they get it. So edibles have been kind of a natural choice for that. As well as the simple act of sharing something; sharing a joint raises a lot of safety risks, especially during the pandemic. It’s a lot easier to share a single gummy out of a bag safely.

Secondly, what I’ve noticed is that parents have their kids at home and yet they still want to consume cannabis as they did before. Edibles have been big because of discretion. So mom or dad can pop a gummy and have a spritzer before dinner and enjoy the night and my theory is happy parents make happy kids. So discretion has been critical.

Then I think there’s a whole round of new entrants that I mentioned before. These are people that maybe smoked weed in college or high school and haven’t touched it for 20 years and now that the stigma has been reduced, they’re coming back to the marketplace and wanting to explore. They may try a vape product, but very few of them want to smoke, as the country is generally pretty anti-smoking.

I think edibles and gummies have been a way for new cannabis consumers, particularly those who are older, to come and enjoy the positive effects, the medical effects and the social lubricant that cannabis offers, while being safe and discreet at the same time. I think COVID has definitely changed the way that that people think about consuming cannabis.

Aaron: Okay, awesome! Lastly, what would you like to learn more about? What are you interested in?

Keith: I have a degree in philosophy and religion. I’m a big fan of the evolution of consciousness. I think that is the container of the story through which we view human civilization and I honestly think we’re at a turning point for how humans in Western society view plant medicine.

I think cannabis is just the first to come along and be legalized. They’ve been doing phase II and III clinical trials on psilocybin and end of life anxiety. People, particularly war veterans, are using ecstasy or MDMA for depression.

What we’re discovering is that what we think we know about the mind is only the tip of the iceberg on how the mind works. I’m interested in exploring how these plant medicines impact individually with our psyche. Secondly, what happens to society when we reach a tipping point and a majority or at least some significant portion are taking these plants and medicines on a regular basis? It opens us up to a whole new perspective on ourselves, on society and on the universe that we live in. So I read a lot in those fields. And that’s what really excites me.

Aaron: Great. So that’s the end of the interview. Thank you for that.

Gas Chromatography/Infrared Spectroscopy: A Tool For the Analysis of Organic Compounds in Cannabis

IR Spectrum of 2,4-Dichlorophenol in different physical states

Editor’s Note: The author will be teaching a 1/2 day short course on this topic at PITTCON in Philadelphia in March 2019.


The combination of gas chromatography and infrared spectroscopy (GC/IR) is a powerful tool for the characterization of compounds in complex mixtures. (1-5) Gas chromatography with mass spectroscopy detection (GC/MS) is a similar technique, but GC/MS is a destructive technique that tears apart the sample molecules during the ionization process and then these fragments are used to characterize the molecule. In GC/IR the molecules are not destroyed but the IR light produced by molecular vibrations are used to characterize the molecule. IR spectrum yields information about the whole molecule which allows the characterization of specific isomers and functional groups. GC/IR is complementary to GC/MS and the combination results in a powerful tool for the analytical chemist.

A good example of the utility of GC/IR vs GC/MS is the characterization of stereo isomers. Stereo isomers are mirror images such as a left hand and a right hand. In nature, stereo isomers are very important as one isomers will be more active then its mirror image. Stereo isomers are critical to medicinal application of cannabis and also a factor in the flavor components of cannabis.

GC/MS is good at identifying basic structure, where GC/IR can identify subtle differences in structure. GC/MS could identify a hand, GC/IR could tell you if it is a left hand or right hand. GC/MS can identify a general class of compounds, GC/IR can identify the specific isomer present.

Why GC/IR?

Gas chromatography interfaced with infrared detection (GC/IR), combines the separation ability of GC and the structural information from IR spectroscopy. GC/IR gives the analyst the ability to obtain information complementary to GC/MS. GC/IR gives the analyst the power to perform functional group detection and differentiate between similar molecular isomers that is difficult with GC/MS. Isomer specificity can be very important in flavor and medical applications.

Gas chromatography with mass spectrometry detection (GC/MS) is the state-of-the-art method for the identification of unknown compounds. GC/MS, however, is not infallible and many compounds are difficult to identify with 100 % certainty. The problem with GC/MS is that it is a destructive method that tears apart a molecule. In infrared spectrometry (IR), molecular identification is based upon the IR absorptions of the whole molecule. This technique allows differentiation among isomers and yields information about functional groups and the position of such groups in a molecule. GC/IR complements the information obtained by GC/MS.

Interfaces

Initial attempts to couple GC with IR were made using high capacity GC columns and stopped flow techniques. As GC columns and IR technology advanced, the GC/IR method became more applicable. The advent of fused silica capillary GC columns and the availability of Fourier transform infrared spectrometry made GC/IR available commercially in several forms. GC/IR using a flow cell to capture the IR spectrum in real time is known as the “Light Pipe”. This is the most common form of GC/IR and the easiest to use. GC/IR can also be done by capturing or “trapping” the analytes of interest eluting from a GC and then measuring the IR spectrum. This can be done by cryogenically trapping the analyte in the solid phase. A third possibility is to trap the analyte in a matrix of inert material causing “Matrix Isolation” of the analyte followed by measuring the IR spectrum.

Infrared Spectroscopy

The physical state of the sample has a large effect upon the IR spectrum produced. Molecular interactions (especially hydrogen bonding) broadens absorption peaks. Solid and liquid samples produce IR spectra with broadened peaks that loses much of the potential information obtained in the spectra. Surrounding the sample molecule with gas molecules or in an inert matrix greatly sharpens the peaks in the spectrum, revealing more of the information and producing a “cleaner” spectrum. These spectra lend themselves better to computer searches of spectral libraries similar to the computer searching done in mass spectroscopy. IR spectral computer searching requires the standard spectra in the library be of the same physical state as the sample. So, a spectrum taken in a gaseous state should be searched against a library of spectra of standards in the gaseous state.

IR of various phases:

  • Liquid Phase – Molecular interactions broaden absorption peaks.
  • Solid Phase – Molecular interactions broaden absorption peaks.
  • Gas Phase – Lack of molecular interactions sharpen absorption peaks.
  • Matrix Isolation – Lack of molecular interactions sharpen absorption peaks.

IR Chromatograms

GC/IR yields chromatograms of infrared absorbance over time. These can be total infrared absorbance which is similar to the total ion chromatogram (TIC) in GC/MS or the infrared absorbance over a narrow band or bands analogous to selected ion chromatogram. This is a very powerful ability, because it gives the user the ability to focus on selected functional groups in a mixture of compounds.

Conclusion

Gas chromatography with infrared detection is a powerful tool for the elucidation of the structure of organic compounds in a mixture. It is complementary to GC/MS and is used to identify specific isomers and congeners of organic compounds. This method is greatly needed in the Cannabis industry to monitor the compounds that determine the flavor and the medicinal value of its products.

Cannabis and the Environment: Navigating the Interplay Between Genetics and Transcriptomics

By Dr. Zacariah Hildenbrand

Dr. Zacariah Hildenbrand

It is that time of year where the holidays afford us an opportunity for rest, recuperation and introspection. Becoming a new father to a healthy baby girl and having the privilege to make a living as a scientist, fills me with an immeasurable sense of appreciation and indebtedness. I’ve also been extremely fortunate this year to spend significant time with world-renowned cannabis experts, such as Christian West, Adam Jacques and Elton Prince, whom have shared with me a tremendous wealth of their knowledge about cannabis cultivation and the development of unique cannabis genetics. Neither of these gentlemen have formal scientific training in plant genetics; however, through decades of experimentation, observation and implementation, they’ve very elegantly used alchemy and the principles of Mendelian genetics to push the boundaries of cannabis genetics, ultimately modulating the expression of specific cannabinoids and terpenes. Hearing of their successes (and failures) has triggered significant wonderment and curiosity with respect to what can be done beyond the genetic level to keep pushing the equilibrium in this new frontier of medicine.

Lighting conditions can greatly impact the expression of terpenes (and cannabinoids) in cannabis.Of course genetics are the foundation for the production of premium cannabis. Without the proper genetic code, one cannot expect the cannabis plant to express the target constituents of interest. However, what happens when you have an elite genetic code, the holy grail of cannabis nucleotides if you will, and yet your plant does not produce the therapeutic compounds that you want and/or that are reflective of that elite genetic code? This ‘loss in translation’ can be explained by transcriptomics, and more specifically, epigenetics. In order for the genetic code (DNA) to be expressed as a gene product (RNA), it must be transcribed, a process that is modulated by epigenetic processes like DNA methylation and histone modification. In other words, the methylation of the genetic code can dictate whether or not a particular segment of DNA is transcribed into RNA, and ultimately expressed in the plant. To put this into context, if the DNA code for the enzyme THCA synthase is epigenetically silenced, then no THCA synthase is produced, your cannabis cannot convert CBGA into THCA, and now you have hemp that is devoid of THC.So what is the best lighting technology to enhance the expression of terpenes? 

With all of that being said, how do we ensure that our plants thrive under favorable epigenetic conditions? The answer is the environment; and the expression of terpenes is an ideal indicator of favorable environmental conditions. While amazing anti-inflammatories, anti-oxidants and metabolic regulators for humans, terpenes are also extremely powerful anti-microbial agents that act as a robust a line of defense for the plant against bacteria and pests. So, if the threat of microbes can induce the expression of terpenes, then what about other environmental factors? I am of the opinion that the combination of increased exposure to bacteria and natural sunlight enhances the expression of terpenes in outdoor-grown cannabis compared to indoor-grown cannabis. This is strictly my opinion based off of my own qualitative observations, but the point being is that lighting conditions can greatly impact the expression of terpenes (and cannabinoids) in cannabis.

So what is the best lighting technology to enhance the expression of terpenes? Do I use full spectrum lighting or specific frequencies? The answer to these questions is that we don’t fully know at this point. Thanks to the McCree curve we have a fundamental understanding of the various frequencies within the visible light spectrum (400-700nm) that are beneficial to plants, also known as Photosynthetically Active Radiation (PAR). However, little-to-no research has been conducted to determine the impacts that the rest of the electromagnetic spectrum (also categorized as ‘light’) may have on plants. As such, we do not know with 100% certainty what frequencies should be applied, and at what times in the growth cycle, to completely optimize terpene concentrations. This is not to disparage the lighting professionals out there that have significant expertise in this field; however, I’m calling for the execution of peer-reviewed experiments that would transcend the boundaries of company white papers and anecdotal claims. In my opinion, this lack of environmental data provides a real opportunity for the cannabis industry to initiate the required collaborations between cannabis geneticists, technology companies and environmental scientists. This is one field of research that I wish to pursue with tenacity and I also welcome other interested parties to join me in this data quest. Together we can better understand the environmental factors, such as lighting, that are acting as the molecular light switches at the interface of genetics and transcriptomics in cannabis.

Applications for Tissue Culture in Cannabis Growing: Part 1

By Aaron G. Biros

Dr. Hope Jones, chief scientific officer of C4 Laboratories, believes there are a number of opportunities for cannabis growers to scale their cultivation up with micropropagation. In her presentation at the CannaGrow conference recently, Dr. Jones discussed the applications and advantages of tissue culture techniques in cannabis growing.

Dr. Hope Jones, chief scientific officer at C4 Labs

Dr. Jones’ work in large-scale plant production led her to the University of Arizona Controlled Environment Agriculture Center (CEAC) where she worked to propagate a particularly difficult plant to grow- a native orchid species- using tissue culture techniques. With that experience in tissue culture, hydroponics and controlled environments, she took a position at the Kennedy Space Center working for NASA where she developed technologies and protocols to grow crops for space missions. “I started with strawberry TC [tissue culture], because of the shelf life & weight compared with potted plants, plus you can’t really ‘water’ plants in space- at least not in the traditional way,” says Dr. Jones. “Strawberries pack a lot of antioxidants. Foods high in antioxidants, I argued, could boost internal protection of astronauts from high levels of cosmic radiation that they are exposed to in space.” That research led to a focus on cancer biology and a Ph.D. in molecular & cellular biology and plant sciences, culminating in her introduction to the cannabis industry and now with C4 Labs in Arizona.

Working with tissue culture since 2003, Dr. Jones is familiar with this technology that is fairly new to cannabis, but has been around for decades now and is widely used in the horticulture industry today. For example, Phytelligence is an agricultural biotechnology company using genetic analysis and tissue culture to help food crop growers increase speed to harvest, screen for diseases, store genetic material and secure intellectual property. “Big horticulture does this very well,” says Dr. Jones. “There are many companies generating millions of clones per year.” The Department of Plant Sciences Pomology Program at the Davis campus of the University of California uses tissue culture with the Foundation Plant Services (FPS) to eliminate viruses and pathogens, while breeding unique cultivars of strawberries.

A large tissue culture facility run in the Sacramento area that produces millions of nut and fruit trees clones a year.

First, let’s define some terms. Tissue culture is a propagation tool where the cultivator would grow tissue or cells outside of the plant itself, commonly referred to as micropropagation. “Micropropagation produces new plants via the cloning of plant tissue samples on a very small scale, and I mean very small,” says Dr. Jones. “While the tissue used in micropropagation is small, the scale of production can be huge.” Micropropagation allows a cultivator to grow a clone from just a leaf, bud, root segment or even just a few cells collected from a mother plant, according to Dr. Jones.

The science behind growing plants from just a few cells relies on a characteristic of plant cells called totipotency. “Totipotency refers to a cell’s ability to divide and differentiate, eventually regenerating a whole new organism,” says Dr. Jones. “Plant cells are unique in that fully differentiated, specialized cells can be induced to dedifferentiate, reverting back to a ‘stem cell’-like state, capable of developing into any cell type.”

Cannabis growers already utilize the properties of totipotency in cloning, according to Dr. Jones. “When cloning from a mother plant, stem cuttings are taken from the mother, dipped into rooting hormone and two to five days later healthy roots show up,” says Dr. Jones. “That stem tissue dedifferentiates and specializes into new root cells. In this case, we humans helped the process of totipotency and dedifferentiation along using a rooting hormone to ‘steer’ the type of growth needed.” Dr. Jones is helping cannabis growers use tissue culture as a new way to generate clones, instead of or in addition to using mother plants.

With cannabis micropropagation, the same principles still apply, just on a much smaller scale and with greater precision. “In this case, very small tissue samples (called explants) are sterilized and placed into specialized media vessels containing food, nutrients, and hormones,” says Dr. Jones. “Just like with cuttings, the hormones in the TC media induce specific types of growth over time, helping to steer explant growth to form all the organs necessary to regenerate a whole new plant.”

Having existed for decades, but still so new to cannabis, tissue culture is an effective propagation tool for advanced breeders or growers looking to scale up. In the next part of this series, we will discuss some of issues with mother plants and advantages of tissue culture to consider. In Part 2 we will delve into topics like sterility, genetic reboot, viral infection and pathogen protection.
