Just as the dust had settled on the news that Canadian LP Aurora had signed agreements to finance a major growing facility in Denmark, the company also added another European feather to its cannabis cap.
On January 18, the company announced that it is the sole and exclusive winner of an EU-wide tender bid to begin to supply medical cannabis to the Italian government through the Ministry of Defense. Why is this federal agency in charge instead of the federal ministry of health? So far, the Italian cannabis program has been overseen exclusively by the Italian military.
But the military just isn’t cut out to cultivate cannabis for the entire medical needs of a country, which should seem obvious. And that is where the Canadian LPs apparently are coming into play.
There were two stages to the bid, with Pedanios, Aurora’s German-based arm prequalifying in the first. In the final round, Pedianos won exclusive rights to begin supplying the government with medical cannabis.
What is interesting, however, is what this says not only about the potential growth of the cannabis market in Italy, but beyond that, Germany.
A German-Canadian Sourced Italian Product?
Pedanios, who won the bid, is the German-based arm of Aurora, one of Canada’s largest LPs. And Italian medical cannabis is now about to be routed by them from Canada, via Berlin, to market locally via pharmacies. It is certainly one of the stranger paths to market globally.
This announcement is even more interesting given that Aurora is widely suspected to be one of the top contenders in the still-pending German bid.
Could this herald a German-sourced cannabis crop for an Italian neighbour?
And what does this say about the sheer amount of volume potentially needed for cultivation next door (or even in Italy) as Germany begins its own cultivation program, presumably this year, to source an already undersupplied domestic market where growing numbers of patients are getting their medical cannabis covered under public health insurance?
Will Germany further antagonize its neighbours over a cannabis trade imbalance? Or does this mean that a spurt of domestic Italian cannabis production is also about to start?
There are 80 million Germans and about 60 million Italians. Who will be the cannabis company to supply them?
Nuuvera Also Makes Italian Moves
Less widely reported, however, was the news that Aurora/Pedanios would not be the only private supplier to the Italian market. Nuuvera, which just announced that they had become finalists in the competitive Germany cultivation bid, also just acquired an import license to Italy for medical cannabis by buying Genoa based FL Group.
One thing is clear. The pattern of establishing presence here by the foreign (mostly Canadian) firms has been one of acquisition and financing partnerships for the past 2 years.
Import until you cultivate is also clearly the guiding policy of legalizing EU countries on the canna front.
The question really is at this point, how long can the import over cultivation preference continue? Especially given the expense of imported cannabis. Not to mention the cannabis farms now popping up all over the EU at a time when the Canadian market will have enough volume from recreational sales to keep all the large (and small) LPs at production capacity for years to come.
In the next year, in fact, look for this reality to start changing. No matter who has import licenses now with flower and oil crossing oceans at this point, within the next 18-24 months, look for this pattern to switch.
The distributors will be the same of course. But the brand (and source) of their product will be from European soil.
Foreign Invasions, Domestic Cultivation Rights & More
One of the more interesting professional conferences this year globally will clearly be the ICBC in Berlin, where all of these swirling competitions and companies come together for what is shaping up to be the most influential cannabis business conference in Europe outside of Spannabis (and with a slightly different approach). Nowhere else in the world now are international companies (from bases in Canada, Australia and Israel primarily) competing in such close proximity for so many foreign cannabis markets and cultivation rights to go with them.
With the average cultivation facility in Europe going for about USD $30-40 million a pop in terms of sheer capital requirements plus the additional capital to finance the inevitable delays, such market presence does not come cheap.
It is increasingly clear that the only business here will also be of the highly regulated, controlled medical variety for some time to come.
That said, when the move towards recreational does come, and within the next four years or so, the global players who have opened these markets on the medical side, will be well positioned to provide product for a consumer base that is already being primed at the pump. Even if for now, the only access is via a doctor’s prescription.
Sunrise Genetics, Inc., the parent company for Hempgene and Marigene, announced last week they have successfully mapped the cannabis genome. The genome map was presented at the 26th Annual Plant and Animal Genome Conference in San Diego, CA during the panel “Cannabis Genomics: Advances and Applications.”
According to CJ Schwartz, chief executive officer of Sunrise Genetics, the full genome map will allow breeders to develop strains using DNA sequence information to complement phenotyping. “In this way a breeding program can be guided by the breeder versus blindly as it is for just pheno-hunting,” says Schwartz. “At the DNA level, we can identify what version of a set of genes a plant contains, and make predictions as to the phenotype, without ever growing the plant. As we make more and more gene markers, we have more genes to track, and breeding becomes more rapid, efficient and precise.” Schwartz says this is essential for breeding stable, repeatable plants. “A commercial strain will be grown in different environments, with solid genetics, the phenotype will mostly stay true, a term we call Genetic Penetrance.”
Determining a plant’s DNA can be extremely valuable and completing the map of the genome now makes this more precise. It can serve as a point of proof, according to Schwartz, providing evidence of lineage in a breeding project and confirming the uniqueness and identity of a strain. The genome map can also allow breeders to select specific genes to develop custom strains. And in addition to all that, it provides legal protection. “Knowing your plants DNA code is the first step to being able take action so no one else can protect it,” says Schwartz. “Well documented evidence in the development of a customized strains is essential to maintaining control of your plant and keeping those you distrust (big pharma) away, many of which have minimal interest in the whole plant anyhow.”
Schwartz says this project took them roughly 18 months to wrap up. “One of the biggest problems was just finding the right plants to grow,” says Schwartz. “In addition we used some emerging technologies and those had some challenges of their own.” According to Schwartz, a key aspect in all this was finding the right collaborators. They ended up working with CBDRx and the plant biology department at the University of Minnesota, where a DEA-licensed lab has been researching cannabis since 2002. “George Weiblen’s group at UM has been working on Cannabis for over a decade,” says Schwartz. “During that time they did repeated selfing to make highly inbred marijuana and hemp lines. The lines were instrumental in deterring the physical order of the genes.”
After finishing up some experiments, they expect to get the genome map published on public domain in less than a year, opening up their research to the general public and allowing breeders and growers to use their data. “This will be a very significant publication,” says Schwartz. “The genome assembly allows for the assimilation of all the currently incompatible Cannabis genome sequence datasets from academia and private companies,” says Schwartz. “Joining datasets from 1000s of strains, and from every continent, will generate an essential public resource for cannabis researchers and aficionados alike.” With a tool like this, we can discover the genes that help produce desirable traits. “This project is a major accomplishment for cannabis, bringing it on par with other important crops, providing a scientific tool to unravel the secrets of this incredibly versatile plant,” says Schwartz.
Sunrise Genetics is assisting cannabis businesses in evaluating strains and developing breeding programs, working with a number of customers currently to develop strains for many different specific traits. “We have the expertise to help select parental strains and guide the selection process at each generation using genotype and phenotype information,” says Schwartz. “Essentially we are bringing all the tools any modern plant breeder would use for improving strawberries to cannabis.”
Regardless of whether your grow is indoor or in a greenhouse, mold is a factor that all cultivators must consider.
After weeks of careful tending, pruning and watering to encourage a strong harvest, all cultivators are looking to sell their crop for the highest market value. A high mold presence, measured through a total yeast and mold count (TYMC), can cause a change of plans by decreasing crop value. But it doesn’t have to.
There are simple steps that any cultivator can take that will greatly eliminate the risk of mold in a grow. Below are some basic best practices to incorporate into your operation to reduce contaminants and mold growth:
Isolate dirty tasks. If you are cleaning pots, filling pots or scrubbing trimming scissors, keep these and other dirty tasks away from grow and process areas. Dirty tasks can contaminate the grow area and encourage mold growth. Set up a “dirty room” that does not share heating, ventilation and air conditioning with clean areas.
Compartmentalize the grow space. Mold can launch spores at speeds up to 55 miles per hour up to eight feet away without any air current. For this reason, if mold growth begins, it can become a huge problem very quickly. Isolate or remove a problem as soon as it is discovered- better to toss a plant than to risk your crop.
No drinks or food allowed. Any drinks or food, with the exception of water, are completely off limits in a grow space. If one of your employees drops a soda on the ground, the sugars in the soda provide food for mold and yeast to grow. You’d be surprised how much damage a capful of soda or the crust of a sandwich can do.
Empty all trash daily. Limiting contaminants in turn limits the potential for issues. This is an easy way to keep your grow clean and sterile.
Axe the brooms. While a broom may seem like the perfect way to clean the floor, it is one of the fastest ways to stir up dirt, dust, spores and contaminants, and spread them everywhere. Replace your brooms with hepa filter backpack vacuums, but be sure that they are always emptied outside at the end of the work day.
No standing water or high humidity. Mold needs water to grow, therefore standing water or high humidity levels gives mold the sustenance to sporulate. Pests also proliferate with water. Remove standing water and keep the humidity level as low as possible without detriment to your plants.
Require coveralls for all employees. Your employee may love his favorite jean jacket, but the odds are that it hasn’t been cleaned in months and is covered with mold spores. Clean clothing for your staff is a must. Provide coveralls that are washed at least once a week if not daily.
Keep things clean. A clean and organized grow area will have a huge impact on mold growth. Clean pots with oxidate, mop floors with oxidate every week, keep the areas in front of air returns clean and clutter-free, and clean floor drains regularly. The entire grow and everything in it should be scrubbed top to bottom after each harvest.
Keep it cool. Keep curing areas cool and storage areas cold where possible. The ideal temperature for a curing area is roughly 60 degrees and under 32 degrees for a storage area. Just like food, the lower the temperature, the better it keeps. High temperature increases all molecular and biological activity, which causes things to deteriorate faster than at cooler temperatures. However, curing temperature is a function of water activity more than anything.
Be Careful With Beneficials. Beneficial insects certainly have their place in the grow environment. However, if you have a problem with mold on only a small percentage of plants, any insect can act as a carrier for spores and exacerbate the problem. By the same token, pests spread mold more effectively than beneficials because they produce rapidly, where beneficials die if there aren’t pests for them to eat. It is best to use beneficials early in the cycle and only when necessary.
Editor’s note: This article should serve as a foundation of knowledge for yeast and mold in cannabis. Beginning in January 2018, we will publish a series of articles focused entirely on yeast and mold, discussing topics such as TYMC testing, preventing yeast and mold in cultivation and treatment methods to reduce yeast and mold.
Cannabis stakeholders, including cultivators, extractors, brokers, distributors and consumers, have been active in the shadows for decades. With the legalization of recreational adult use in several states, and more on the way, safety of the distributed product is one of the main concerns for regulators and the public. Currently, Colorado1, Nevada and Canada2 require total yeast and mold count (TYMC) compliance testing to evaluate whether or not cannabis is safe for human consumption. As the cannabis industry matures, it is likely that TYMC or other stringent testing for yeast and mold will be adopted in the increasingly regulated medical and recreational markets.
The goal of this article is to provide general information on yeast and mold, and to explain why TYMC is an important indicator in determining cannabis safety.
Yeast & Mold
Yeast and mold are members of the fungi family. Fungus, widespread in nature, can be found in the air, water, soil, vegetation and in decaying matter. The types of fungus found in different geographic regions vary based upon humidity, soil and other environmental conditions. In general, fungi can grow in a wide range of pH environments and temperatures, and can survive in harsh conditions that bacteria cannot. They are not able to produce their own food like plants, and survive by breaking down material from their surroundings into nutrients. Mold cannot thrive in an environment with limited oxygen, while yeast is able to grow with or without oxygen. Most molds, if grown for a long enough period, can be detected visually, while yeast growth is usually detected by off-flavor and fermentation.
Due to their versatility, it is rare to find a place or surface that is naturally free of fungi or their spores. Damp conditions, poor air quality and darker areas are inviting environments for yeast and mold growth.
Cannabis plants are grown in both indoor and outdoor conditions. Plants grown outdoors are exposed to wider ranges and larger populations of fungal species compared to indoor plants. However, factors such as improper watering, the type of soil and fertilizer and poor air circulation can all increase the chance of mold growth in indoor environments. Moreover, secondary contamination is a prevalent risk from human handling during harvest and trimming for both indoor and outdoor-grown cannabis. If humidity and temperature levels of drying and curing rooms are not carefully controlled, the final product could also easily develop fungi or their growth by-product.
What is TYMC?
TYMC, or total yeast and mold count, is the number of colony forming units present per gram of product (CFU/g). A colony forming unit is the scientific means of counting and reporting the population of live bacteria or yeast and mold in a product. To determine the count, the cannabis sample is plated on a petri dish which is then incubated at a specific temperature for three to five days. During this time, the yeast and mold present will grow and reproduce. Each colony, which represents an individual or a group of yeast and mold, produces one spot on the petri dish. Each spot is considered one colony forming unit.
Why is TYMC Measured?
TYMC is an indicator of the overall cleanliness of the product’s life cycle: growing environment, processing conditions, material handling and storage facilities. Mold by itself is not considered “bad,” but having a high mold count, as measured by TYMC, is alarming and could be detrimental to both consumers and cultivators.
The vast majority of mold and yeast present in the environment are indeed harmless, and even useful to humans. Some fungi are used commercially in production of fermented food, industrial alcohol, biodegradation of waste material and the production of antibiotics and enzymes, such as penicillin and proteases. However, certain fungi cause food spoilage and the production of mycotoxin, a fungal growth by-product that is toxic to humans and animals. Humans absorb mycotoxins through inhalation, skin contact and ingestion. Unfortunately, mycotoxins are very stable and withstand both freezing and cooking temperatures. One way to reduce mycotoxin levels in a product is to have a low TYMC.
Yeast and mold have been found to be prevalent in cannabis in both current and previous case studies. In a 2017 UC Davis study, 20 marijuana samples obtained from Northern California dispensaries were found to contain several yeast and mold species, including Cryptococcus, Mucor, Aspergillus fumigatus, Aspergillus niger, and Aspergillus flavus.3 The same results were reported in 1983, when marijuana samples collected from 14 cannabis smokers were analyzed. All of the above mold species in the 2017 study were present in 13 out of 14 marijuana samples.4
Aspergillus species niger, flavus, and fumigatus are known for aflatoxin production, a type of dangerous mycotoxin that can be lethal.5 Once a patient smokes and/or ingests cannabis with mold, the toxins and/or spores can thrive inside the lungs and body.6, 7 There are documented fatalities and complications in immunocompromised patients smoking cannabis with mold, including patients with HIV and other autoimmune diseases, as well as the elderly.8, 9, 10, 11
For this reason, regulations exist to limit the allowable TYMC counts for purposes of protecting consumer safety. At the time of writing this article, the acceptable limit for TYMC in cannabis plant material in Colorado, Nevada and Canada is ≤10,000 CFU/g. Washington state requires a mycotoxin test.12 California is looking into testing for specific Aspergillus species as a part of their requirement. As the cannabis industry continues to grow and advance, it is likely that additional states will adopt some form of TYMC testing into their regulatory testing requirements.

In rather shocking news out of Germany on the cannabis front, it appears that Canadian LP ABcann has not been selected as one of the finalists in the country’s first tender bid to cultivate cannabis domestically.
As reported in the German press, the company has not been invited to submit an offer in the final award procedures. The reason per a company spokesman as quoted in the German media? The company proved it met the required qualification thresholds – namely it could deliver the required amount of product as required by the German government. However the amount it could produce was less than other firms being considered.
That is a strange statement, especially because the ten licenses on offer only called for a total of 2,000 kgs of production total by 2019 and 6600 kgs by 2022.
Who Is ABCann?
ABcann has been in business since 2014 in Canada, when it received one of the first cultivation licenses issued by the Canadian government. It has also been aggressively positioning itself in the German and European market this year – and in multiple ways. It got itself listed on both American and German stock exchanges by summer. The company established a subsidiary headquarters in Schönefeld as of August 2017. As late as October, the company also was appearing at industry conferences, like the IACM medical conference in Cologne, as an expected finalist in the first bid.
However, the company’s plans to build a $40 million, 10,000 square meter plant somewhere in Lusatia are now also reportedly on hold. The exact location of the plant is unknown, per German government requirements that grow facilities remain secret. That said, with a year and a half to complete construction, if given the green light even by early next year, it may be that this was the reason the company has apparently not made the cut. Or perhaps the German government did not believe the company was adequately funded. A September exercise of warrants netted the company an additional $45 million in operating cash. But with expansion plans in not only Canada and Europe, but Australia too, did the company pass the German test for liquidity?
Management changes are also afoot. As of October 1, Barry Fishman, a former Eli Lilly executive took over as CEO of ABCann Global. Ken Clement, founder of the company, announced in mid-October that he was stepping down from his position as Executive Chair of the Board to be replaced by Paul Lucas a former President and CEO of GlaxoSmithKline Canada. John Hoff, the Geschäftsführer (or CEO) of ABcann’s German subsidiary, has also recently left the company. When asked by CannabisIndustryJournal about his reasons for doing so at the Cannabis Normal conference in Berlin at the beginning of November, Hoff cited “management and creative differences” with ABcann Canada as the impetus for his recent departure.
However with the news of ABcann’s apparent loss of a front-runner position in the pending bid, such news appears to herald a bit more of a shakeup at the company, if not a refocussing of overall global strategy.
A source within the company who wished to remain anonymous also said this when contacted directly by CannabisIndustryJournal. “Our top priority currently is to acquire an import license. We also fully intend to pursue all of our plans in the German market, but we have no firm dates on the construction front.”
The State of Medical Cannabis Reform Auf Deutsch
The German medical cannabis question has certainly jerked forward over the past several years through several rough patches. This year it has gotten even stranger. And nobody is quite sure where it will end up.
The news about ABcann is also the latest episode in a very strange story that has continued to develop mostly out of sight of the public.
That bid process, which was expected to announce the winners by late summer, has now dragged on through the fall.Germany began moving forward quietly on the cannabis issue in the first decade of the century. Patients could only access the drug in basically trial mode. Most patients who qualified with a doctor’s prescription and a special permit to take the drug, could also access only Sativex (which is very expensive) or the synthetic form of the drug, dronabinol, manufactured domestically in a facility near Frankfurt. All bud cannabis was imported from Holland by Bedrocan. Strictly controlled not by German, but rather Dutch law on cannabis imports.
In 2014, the first German patients successfully sued the government to grow their own plants if their insurance companies refused coverage of the drug and they proved they could not afford alternatives.
This year, in January, the German government voted unanimously to change the law to mandate public health insurance. The law went into effect in March. Mainly driven by a desire to halt home-grow, the rules changed again. Post March 2017, patient grow rights have now been revoked. Now patients are theoretically allowed to get cannabis covered under public health insurance. In reality, the process has been difficult.
In April, the German government created a new “Cannabis Agency” under the auspices of BfArM. And BfArM in turn issued a tender bid for the country’s first domestic licences in April.
That bid process, which was expected to announce the winners by late summer, has now dragged on through the fall.
When Will The Winners Be Announced?
That too is unclear. It is very likely that the final announcement will not be made by the government until the beginning of the year – after the new government is formed. The so-called “Jamaica Coalition” – of the mainstream CDU, the Greens and the liberals (FDP) is under major pressure to address the issue of access. So far Chancellor Angela Merkel has signalled her resistance for additional changes to the new cannabis law. That said, the current situation in Germany, which is untenable for patients and doctors, as well as companies trying to enter the market and investing heavily, is unlikely to hold for even the next several years.
Problems with finding doctors and medical reimbursement under insurance have kept this patient population from growing the way it would otherwise.In late October, the news broke that two legal complaints had been unsuccessfully filed against the bid itself. Both parties’ complaints were dismissed. Yet there also appears to have been a third complaint that has actually devolved in to a real Klage – or lawsuit. Lexamed GmbH’s claim directly addresses issues expressed by many German-only firms this year. Namely that they were unfairly left out of the bid process because of a supposed lack of experience. As such it is likely to be closely watched by other existing German hopefuls.
This lawsuit has now formally delayed the announcements on the bid decision until at least after December 20th of this year, when the oral arguments will be heard in the case. A decision about the bid will go forward when this has been decided, by the beginning of 2018.
In the meantime? Cannabis imports are starting to enter the country. In late summer last year, Spektrum Cannabis, formerly MedCann GmbH, located just south of Frankfurt, received the first import licenses from the German government to bring medical cannabis into Germany from Canada. Both Aurora and Tilray were granted import licenses this fall.
There are 16 different kinds of cannabis on the market right now. And about 170 kilos of cannabis were imported into the country in the last year. There are also currently about 1,000 patients although this number is artificially low. Problems with finding doctors and medical reimbursement under insurance have kept this patient population from growing the way it would otherwise. There are easily a million patients in Germany right now who would qualify for cannabis if the system worked as it was originally intended in the legislation passed in January.
That said, despite the recent news that ABcann is “out” – at least for this round– apparently the pan-European bid process is still very much alive, despite many recent rumours that it was dead in the water. And plans also seem to be afoot for a separate and additional cultivation licensing round potentially as soon as next year. Details however are unclear and nobody either in the industry or the government is willing to be quoted or give any further information.
There is a great deal to be happy about with medical cannabis legalization in Germany. This is the first country that has mandated insurance coverage of the drug – at least at the federal legislative level.
However, as the government evaluates the finalists in the first tender bid for domestically grown and regulated cannabis, a real crisis is brewing for patients on the ground. And further one that the industry not only sees but is trying to respond to.
Spektrum Cannabis GmbH, formerly MedCann GmbH began trying to address this problem when they obtained the first import license for Canadian cannabis last year. They are also one of the apparent five finalists in the pending government bid to grow the plant domestically for medical purposes. According to Dr. Sebastian Schulz, head of communications for Spektrum, “Shortly after the new cannabis law was reformed we experienced a huge increase in demand from the side of patients. We had prepared for that. The German population is very curious about cannabis as a medicine and in general very open to natural remedies.”
People are curious here. But like other places, the law in Germany has evolved slowly. Much like Israel, the government has allowed a trickle of patients to have access to cannabis by jumping through multiple, time consuming hoops. The process of getting cannabis prescribed, much less getting a pharmacy to stock it, was difficult. Patients had to pay out of pocket – a monthly cost of about $1,700. While that is expensive by American standards, to Germans, this is unheard of. The vast majority of the population – 90% – is on public health insurance. That means that most Germans get medications for $12 a month, no matter what they are. Allegedly, German patients were supposed to get about 5oz a month for this price. At least that is what the law says.
People are curious here. But like other places, the law in Germany has evolved slowlyAs in other countries, no matter what Germans think about recreational reform, the clear majority of them at this point support medical use. And at this point, both legislatively and via the courts, the government has said and been required to provide the drug to Germans patients at low cost.
Unintended Effects & Consequences
Since the law went into effect in March of this year however, things have suddenly turned very dire for patients.
The handful of people who had the right to grow at home – established under lawsuits several years ago – were suddenly told they could no longer do so. They had to go to a doctor and regular pharmacy. Even regular patients in the system found that their insurance companies, allegedly now required to pay, are refusing to reimburse claims. Doctors who prescribed the drug were abruptly informed that they would be financially responsible for every patient’s drug cost for the next two years (about $50,000 per patient).
To add a final blow to an already dire situation, German pharmacies that carried the drug, then announced an additional fee. It is about $9 extra per gram, added at the pharmacy, pushing the price of legitimate cannabis north of $20 dollars per gram. This is justified as a “preparation fee.” Cannabis bud is technically marked as an “unprocessed drug.” This means the pharmacies can charge extra for “processing” the same. In reality this might be a little bud trimming. If that. The current distributors in the market already prep and pre-package the drug.
What this bodes for a future dominated by infused products, oils and concentrates is unclear. However the impact now is large, immediate and expensive in a country where patients also must still go to the pharmacy in person for all prescription drugs.
There is no mail order here, by federal law. Online pharmacies are a luxury for Auslanders.
At minimum, this could mean that without some relief, German patients will go right back into the black market and home grow.While nobody has challenged this situation yet en masse, it is already a sore point not only for patients but across the industry. It means that an already expensive drug has gotten even more expensive. It also means that the government regulations are not working as planned.
At least not yet. For the large Canadian companies now coming into the market with multimillion-dollar investments already sunk in hard costs, Germany will be a loss-leader until the system sorts itself out.
According to Schulz, whose company is now in the thick of it, the new law is very vague. “Currently, there are almost no cannabis flowers available in German pharmacies because companies like us are not allowed to sell them,” says Schulz. “Various different regulatory demands come up that seemed to change on a monthly basis. We are ready to deliver even large amounts of cannabis for a market that might well explode soon – but we first need to overcome the regulatory nightmare that leads to the suffering of so many patients here these days.”
At minimum, this could mean that without some relief, German patients will go right back into the black market and home grow. Black market costs for cannabis are about $10-15 a gram. In other words, exactly the situation the government was hoping to avoid.
What Is Causing The Situation?
The intended effect of the legislation was twofold, according to industry insiders: To legalize cannabis in such a way to meet a rising public demand and, in the face of a court decision, to limit the home grow movement. The latter of which, despite federal regulations, is thriving here. Germans like to grow things, and cannabis is a rewarding plant to nurture.
High attendance at the Mary Jane Grow Expo in Berlin in June is just one sign that the genie is out of this particular bottle. BfArM – the federal agency in charge of regulating narcotics and medical devices – cannot stuff it back.Patients are going back to the way things were
However home grow does not build a professional, high volume cannabis market, much less a highly regulated medical one make. The government also made clear that it is going to have strict inspections and quality controls, and will technically buy all the cannabis produced, per the terms of the bid application process.
However, it is not entirely clear when the government will start actually doing the buying. And why the buying has not started yet. If insurance companies are refusing to pay, this means the government is not reimbursing them. The same government, which has also agreed to do so, as of March 2017.
What Gives On Good Old German Efficiency?
On the streets, patients are going back to the way things were. Many are used to fighting for the only drug that makes them feel better. The euphoria in May, for example, has been replaced with weary acceptance that things might get a bit worse before they really improve.
That said, there is also a realization that more activism and lobbying are required on just about every front. If an extrapolation of data from say Colorado or California is applied to Germany, there are already at least a million eligible patients here, based on the qualifying conditions. The government is planning for an annual increase in medical patients of about 5-10,000 a year, including in the amount of cannabis they are planning on buying from the licensed producers they choose. The numbers, however, are already not matching.Even existing patients are literally being forced into the black market again.
Added to this wrinkle is the other reality that is also looming, particularly now.
With one exception, all of the firms now apparently in contention as finalists for the German government bid will also be supplying a domestic market in Canada that is going rec next summer. One year, in other words, before the German companies even begin producing.
What Is The Upshot For Patients?
Guenther Weiglein is one of the five patients who sued for home grow rights in 2014. He is now suing again for the right to extend home grow privileges until the government figures out its process. He is not the only one. Earlier this year he was told he had to stop his home grow and integrate into the “mainstream” system. So far, he, along with other patients who are suing, including for insurance coverage, have not been able to get cannabis easily through the system, although they are starting to make progress.
Weiglein’s situation is made even more frustrating by the fluidity of the situation. As of late July, he had finally gotten agreement from his insurance company to cover the drug. But now he cannot find a doctor willing to accept the financial risk of prescribing it to him. And in the meantime he has no access to medication.
Talk to any group of advocates right now, and there is one ongoing story. Even existing patients are literally being forced into the black market again.
And those that can’t afford it? They are out of luck. Some patients say a tragedy like someone dying will create the impetus to move this into public eye. A hunger strike here by a leading cannabis doctor earlier this summer has so far not had much impact on policy. There is a great deal of pessimism here, as promised change earlier this year has turned into a long and drawn out multiyear question mark.
If this sounds like a bubbling and untenable situation, especially before a national election, it is. The prospect of another four years of Angela Merkel does not bode well for fast cannabis reform.
That said, the German government is now in an interesting situation. The law has now clearly changed to say that sick Germans are allowed to use cannabis as a drug of choice for chronic diseases when all else fails. Further, the national government has bound the insurance industry to cover it. So far, every patient who has sued for coverage has won. That has not, however, moved the insurance industry altogether. Nor has it solved the problem with doctors prescribing the drug.
Many now ask what will? It is clear, however, that it will change. The question is when, how fast, and in what situations.
The problem will undoubtedly ease by 2019, when the first German crops are finally ready, although it will be far from completely solved.
The Pennsylvania Department of Health announced today the first 12 winners of growing and processing permits for the state’s medical cannabis program. At first glance, it appears those who won the permits have teams with experience in successful cannabis operations elsewhere in the country. The permit winners now have six months to become operational, according to a press release.
According to that press release, John Collins, director of the Pennsylvania Office of Medical Marijuana, received 457 applications in total, with 177 prospective grower/processors and 280 for dispensaries. “With today’s announcement, we remain on track to fulfill the Wolf Administration’s commitment to deliver medical marijuana to patients in 2018,” says Collins. “The applications from the entities receiving permits were objectively reviewed by an evaluation team made up of members from across commonwealth agencies.”
In the populous Southeast region of Pennsylvania, grower/processor permits were awarded to Prime Wellness of Pennsylvania, LLC, and Franklin Labs, LLC. Prime Wellness is a Connecticut-based enterprise. According to Steve Schain, Esq., attorney at the Hoban Law Group, Franklin Labs includes team members from Garden State Dispensary, a successful medical cannabis operation in New Jersey.
Two of the businesses that won permits are actually from Illinois, not Pennsylvania. GTI Pennsylvania, LLC (Green Thumb Industries), has a strong presence in Illinois and Nevada. AES Compassionate Care LLC lists their business state as Illinois as well.
“Based on the first phase award of grower/processor licensees both the strength and weakness of Pennsylvania’s program has been highlighted,” says Schain. “Many licensee recipients are affiliated with existing national marijuana-related businesses with excellent track records for operating in a transparent, compliant and profitable manner.” The applications were rated on a scorecard out of 1,000 points. “Unfortunately missing from this initial phase license winners are purely regional enterprises who may have been unable to compete with national concerns’ resources and checkbooks.” According to Schain, some of the more significant areas on the scorecard reflect a diversity plan, community impact statement, business history and capacity to operate, capital requirements and operational timetable. Capital requirements are the applicants’ demonstrable financial resources comprised of at least $2 million in capital and $500,000 in cash. All of the growers are required to grow indoors, not in a greenhouse or on an outdoor farm.
There is also a ten-day appeals process for scorecards that will undoubtedly be utilized by companies that were not successful in their bids. The next phase, according to Schain, of Pennsylvania’s Medical Marijuana Program regards “Clininical Registrants” in which grow/processor and dispensary licensure will be awarded to eight applicants, which, if able to satisfy requirements including demonstrating $15 million in capital, will be authorized to open up to six dispensary locations.
In the first part of this series, we introduced some relevant terms and principles to tissue culture micropropagation and reviewed Dr. Hope Jones’ background in the science of it. In the second part, we went into the advantages and disadvantages of using mother plants to clone and why tissue culture could help growers scale up. In the third part of this series, we are going to examine the five steps that Dr. Jones lays out to successfully micropropagate cannabis plants from tissue cultures.
Cleaning – Stage 0
Micropropagation includes 5 stages. “Stage 0 is the preparation of mother plants and harvest of cuttings for the explant material,” says Dr. Jones. “To ensure the best chance of growing well in culture, those ladies [the mom’s] should be cleaned up and at their best. And hopefully not stressed by insects or pathogens.” She says growers should also make sure the plants are properly fertilized and watered before harvesting explants. “Obtaining the explants is done with a clean technique using new disposable blades and gloves,” says Dr. Jones. “Young shoot tips are harvested and placed in labeled, large Ziploc bags with a small amount of dilute bleach and surfactant solution, then placed in a cooler and taken to the lab.” This is a process that could be documented with record keeping and data logs to ensure the same care is taken for every explant. “Once in the lab, working in the sterile environment of the transfer hood, the cuttings are sterilized, typically with bleach and a little surfactant, and then rinsed several times with sterile water,” says Dr. Jones. Once they reach the sterile environment, Dr. Jones removes the leaves and cuts the stem down to individual nodes.
Establishment – Stage 1
Establishment essentially means waiting for the shoots to develop. Establishing the culture requires an absolutely sterile environment, which is why the first step is so important. “Proper explant disinfection is equally as important is the control parameters of the facility itself,” says Dr. Jones. Mother plants are not grown in sterile facilities, but in an environment that is invariably contaminated with dust, which harbors micro-organisms, insects and other potential sources of contamination, including human handling. We discussed some of this in Part 2.
Explants, once sterilized and placed in the culture vessel, must establish to the new aseptic conditions. “Basically Stage 0 ends when the explants are cleaned and placed in the vessel. Stage 1 begins on the shelf while we patiently sit, watch and wait for the shoot growth,” says Dr. Jones. “Successful establishment means we properly disinfected the explants because the cultures do not become contaminated with bacteria or fungi and new shoot growth emerges.”
Multiplication – Stage 2
This stage is rather self-explanatory as multiplication simplified means generating many more shoots per explant. In order to create a large number of plants needed for meeting the demand of weekly clone orders, Dr. Jones can break up, or subculture, one explant that contains multiple numerous new shoots. “Let’s say one vessel, which originally started with 4 explants each developed four new shoots. Working in the hood, I remove each explant from the vessel and place it on a sterile petri dish. Now I can divide each explant into 4 new explants and then place the four new explant cuttings into their own vessel. In this example, we started with one vessel with 4 explants,” says Dr. Jones. “Which when subcultured 4-6 weeks later, we now have 4 vessels with 16 plants.” This is instrumental in understanding how tissue culture micropropagation can help growers scale without the need for a ton of space and maintenance. From a single explant, you can potentially generate 70,000 plants after 48 weeks, according to Dr. Jones. “Starting with not 1, but 10 or 20 explants would significantly speed up multiplication.” Using tissue culture effectively, one can see how a grower can exponentially increase their production.
Rooting – Stage 3
“When the decision is made to move cultures to the rooting stage, we typically need to subculture the plantlets to a different media formulated to induce rooting,” says Dr. Jones. “In some instances, the media is very dark, and that’s because of the addition of activated charcoal.” Using activated charcoal, according to Dr. Jones, helps darken the rooting environment, which closely mimics a normal rooting environment. “It helps remove high levels of cytokinin and other possible inhibitory compounds,” says Dr. Jones. Cytokinins are a type of plant growth hormone commonly used to promote healthy shoot growth, but it is important to make sure the culture contains the right ratio of hormones, including cytokinin and auxin for maximum root and shoot development. Dr. Jones suggests that growers research their own media formulation to ensure nice, healthy roots develop and that no tissue dies in the process. “With everything I grow in culture, when it comes to media, in any stage and with all new strains, I run some simple experiments in order to refine the media used,” says Dr. Jones. She puts a special focus on the concentrations and ratios of plant hormones in formulating her medias.
“We commonly think of auxin’s role in rooting, but it’s also important in leaves and acts as a regulator of apical shoot dominance,” says Dr. Jones. “So having no auxin may not be ideal for the shooting media used in Stages 1 and 2.” Auxin is a plant hormone that can help promote the elongation of cells, an important step in any plant’s growth. “And cytokinins are typically synthesized in the root and moves through xylem to shoots to regulate mitosis as well as inducing lateral bud branching, so again finding that nice balance between these two hormones is key.”
Acclimation & Hardening Off – Stage 4
“When plants have developed good looking healthy roots, it’s time to pop the top,” says Dr. Jones. This means opening the vessel, another risk for contamination, which is why having a clean environment is so crucial. “The location of these vessels needs to be tightly controlled for light, relative humidity, temperature and cleanliness.” In the culture, sugar is a main ingredient in the medium, because the growing explants are not very photosynthetically active. “By opening the lid of the vessel, carbon dioxide is introduced to the environment, which promotes and enhances photosynthesis, really getting the plants ready for cultivation.”
The very final step in tissue culture micropropagation is hardening, which involves the formation of the waxy cuticle on the leaves of the plant, according to Dr. Jones. This is what preps the plant to actually survive in an unsterile environment. “The rooted plants are removed from the culture vessel, the media washed off and placed in a potting mix/matrix or plug and kept in high humidity and low light,” says Dr. Jones. “Now that there is no sugar, contamination is no longer a threat, and these plants can be moved to the grow facility.” She says conditioning these plants can take one or two weeks. Over that time, growers should gradually increase light intensity and bring down the relative humidity to normal growing conditions.
Overall, this process, if done efficiently, can take roughly eleven weeks from prepping the explants to acclimation and hardening. If growers perform all the steps correctly and with extra care to reduce risks of contamination, one can produce thousands of plants in a matter of weeks.
In the fourth and final part of this series, we are going to dive into implementation. In that piece, we will discuss design principles for tissue culture facilities, equipment and instrumentation and some real-world case studies of tissue culture micropropagation.
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. 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.
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.
Oxygen plays an integral role in plant photosynthesis, respiration and transpiration. Photosynthesis requires water from the roots making its way up the plant via capillary action, which is where oxygen’s job comes in. For both water and nutrient uptake, oxygen levels at the root tips and hairs is a controlling input. A plant converts sugar from photosynthesis to ATP in the respiration process, where oxygen is delivered from the root system to the leaf and plays a direct role in the process.
Charlie Hayes has a degree in biochemistry and spent the past 17 years researching and designing water treatment processes to improve plant health. Hayes is a biochemist and owner of Advanced Treatment Technologies, a water treatment solutions provider. In a presentation at the CannaGrow conference, Hayes discussed the various benefits of dissolved oxygen throughout the cultivation process. We sat down with Hayes to learn about the science behind improving cannabis plant production via dissolved oxygen.
In transpiration, water evaporates from a plant’s leaves via the stomata and creates a ‘transpirational pull,’ drawing water, oxygen and nutrients from the soil or other growing medium. That process helps cool the plant down, changes osmotic pressure in cells and enables a flow of water and nutrients up from the root system, according to Hayes.
Roots in an oxygen-rich environment can absorb nutrients more effectively. “The metabolic energy required for nutrient uptake come from root respiration using oxygen,” says Hayes. “Using high levels of oxygen can ensure more root mass, more fine root hairs and healthy root tips.” A majority of water in the plant is taken up by the fine root hairs and requires a lot of energy, and thus oxygen, to produce new cells.
So what happens if you don’t have enough oxygen in your root system? Hayes says that can reduce water and nutrient uptake, reduce root and overall plant growth, induce wilting (even outside of heat stress) in heat stress and reduce the overall photosynthesis and glucose transfer capabilities of the plant. Lower levels of dissolved oxygen also significantly reduce transpiration in the plant. Another effect that oxygen-deprived root systems can have is the production of ethylene, which can cause cells to collapse and make them more susceptible to disease. He says if you are having issues with unhealthy root systems, increasing the oxygen levels around the root system can improve root health. “Oxygen starved root tips can lead to a calcium shortage in the shoot,” says Hayes. “That calcium shortage is a common issue with a lack of oxygen, but in an oxygen-deprived environment, anaerobic organisms can attack the root system, which could present bigger problems.”
So how much dissolved oxygen do you need in the root system and how do you achieve that desired level? Hayes says the first step is getting a dissolved oxygen meter and probe to measure your baseline. The typical dissolved oxygen probe can detect from 20 up to 50 ppm and up to 500% saturation. That is a critical first step and tool in understanding dissolved oxygen in the root system. Another important tool to have is an oxidation-reduction potential meter (ORP meter), which indicates the level of residual oxidizer left in the water.
Citing research and experience from his previous work, he says that health and production improvements in cannabis plateau at the 40-45 parts-per-million (ppm) of dissolved oxygen in the root zone. But to achieve those levels, growers need to start with an even higher level of dissolved oxygen in a treatment system to deliver that 40-45 ppm to the roots. “Let’s say for example with 3 ppm of oxygen in the root tissue and 6ppm of oxygen in the surrounding soil or growing medium, higher concentrations outside of the tissue would help drive absorption for the root system membrane,” says Hayes.
Reaching that 40-45 ppm range can be difficult however and there are a couple methods of delivering dissolved oxygen. The most typical method is aeration of water using bubbling or injecting air into the water. This method has some unexpected ramifications though. Oxygen is only one of many gasses in air and those other gasses can be much more soluble in water. Paying attention to Henry’s Law is important here. Henry’s Law essentially means that the solubility of gasses is controlled by temperature, pressure and concentration. For example, Hayes says carbon dioxide is up to twenty times more soluble than oxygen. That means the longer you aerate water, the higher concentration of carbon dioxide and lower concentration of oxygen over time.
Another popular method of oxidizing water is chemically. Some growers might use hydrogen peroxide to add dissolved oxygen to a water-based solution, but that can create a certain level of phytotoxicity that could be bad for root health.
Using ozone, Hayes says, is by far the most effective method of getting dissolved oxygen in water, (because it is 12 ½ times more soluble than oxygen). But just using an ozone generator will not effectively deliver dissolved oxygen at the target levels to the root system. In order to use ozone properly, you need a treatment system that can handle a high enough concentration of ozone, mix it properly and hold it in the solution, says Hayes. “Ozone is an inherently unstable molecule, with a half-life of 15 minutes and even down to 3-5 minutes, which is when it converts to dissolved oxygen,” says Hayes. Using a patented control vessel, Hayes can use a counter-current, counter-rotational liquid vortex to mix the solution under pressure after leaving a vacuum. Their system can produce two necessary tools for growers: highly ozonized water, which can be sent through the irrigation system to effectively destroy microorganisms and resident biofilms, and water with high levels of dissolved oxygen for use in the root system.
