Earlier this week, a series of wildfires began ripping through Napa, Sonoma and Mendocino Counties, causing mandatory evacuations, rampant property damage and taking the lives of at least 17 people. Extraordinarily high wind gusts up to 50 mph have swept through communities in Northern California, leaving complete destruction in its wake.
According to The Washington Post, flames have reached more than 170,000 acres since Sunday when the fires began. The cause is still unknown. The President declared a state of emergency, allowing emergency funds to go to clearing debris and supplies for shelters. Nearly 25,000 have fled their homes to shelters in seven counties.
The area is well known for its wine production, an industry that is taking a very hard hit from the wildfires. It is also known as a productive cannabis growing area as part of the Emerald Triangle, synonymous with high quality, outdoor cannabis farms. A number of cannabis farms have been severely impacted by the flames.
We’ve received numerous reports of growers fleeing their homes and farms to get to safety. The LA Times reported that at least seven cannabis farms have been engulfed in flames. According to Amanda Reiman, vice president of community relations at Flow Kana, a distribution company working with cannabis farmers in the Emerald Triangle, they are in active evacuations and the fire is only about 5% contained. “It will be a while before we know the extent of the damage to our farmers and our community,” says Reiman. “The Emerald Triangle is a large region and central Mendocino county contributes a lot. Our farmers are resilient, but right now we are all focused on safety and vigilance.”
Kristin Nevedal, founder and chair of International Cannabis Farmers Association (ICFA), says she’s received information about cannabis farms being destroyed. “The true extent of damage to farms, lives and communities won’t unfortunately be known for sometime,” says Nevedal. “There is no rain in the immediate forecast, conditions are dry and we have had high winds.” Nevedal says the damage goes way beyond just a business setback. “Traditional sun grown cannabis farmers often live on the property they farm, so for many, a forest fire can mean not only loosing the crop but also their homes,” says Nevedal. “While there are fire insurance policies available for houses and outbuildings, the operational infrastructure components and the crop itself can be challenging or impossible to insure.” She says things like water storage tanks, water supply systems, irrigation systems, fences, water pumps and solar systems might not be insured at all. “Law enforcement in Mendocino is coordinating, to the best of their ability, with evacuees who have fire damage or have been evacuated, to insure public safety while assisting folks with repopulating their property and/or assessing the status of fire damage,” says Nevedal.
Because California is expected to implement their full adult use legalization in early 2018, the wildfires are particularly devastating to businesses that have been gearing up for the new market. To make matters worse, the fires came during peak harvest time, while growers are cutting plants and preparing their entire crops for distribution and sale.
Devika Maskey, founder of TSO Sonoma, a cannabis farm in Sonoma County, could only speak briefly because her farm is under evacuation orders. “We are getting all personnel off the hill to safety,” says Maskey. “The wind will be picking up to 40-50mph again later today.” Those high winds have the potential to spread the flames quicker, destroying more property and putting more lives at risk.
Maskey says the wildfires are having an enormous impact on their crops this year. “We do not have enough time to harvest the outdoor crop,” says Maskey. “So far there has been clear skies, but if the fire gets closer it can taint the buds with a smoky smell and flavor.”
Maskey says she has a number of friends in the cannabis space that have been severely affected already. “We do have a few friends that have lost their farms already,” says Maskey. “About a dozen other friends and family members who have lost their homes.” In Sonoma County alone, 5,000 people have been evacuated to shelters as of Wednesday morning, reports The Washington Post. “This has been a devastating week for many people and businesses,” says Maskey. “Our priority is getting everyone off the hill and to safety.” If you want to help the cannabis growers impacted by the fires, Maskey recommends donating to this growers relief fund or donate to the North Bay Fire Relief fund here.
In July, we sat down with the folks at Digipath, Inc. when they received their testing license in Nevada for the adult use market. In that conversation, they mentioned they were looking to expand into California.
According to a press release published September 25th, DigiPath, Inc. has entered a joint venture to establish their first cannabis-testing lab in California. They will be working with Don Ashley, an experienced real estate developer and cannabis entrepreneur, to launch Humboldt Botanical, LLC, conducting business under the name “Digipath Botanical Testing”.
Ashley says they expect to be fully operational by Q1 of 2018. “We expect to break ground on this project in the next few weeks and hope to be operational in early Q1 2018 just after the state-wide adult-use market is expected to launch, as we have already obtained approval from the local planning authorities for the entire complex,” says Ashley.
Todd Denkin, president of Digipath, is optimistic for California’s market and the coming regulations. “The state of California is estimated to be the single largest cannabis market in the U.S. Adult-use cannabis legislation was approved by California residents last November, and we expect these new regulations to be implemented in 2018,” says Denkin. “The good news for the industry is that the requirements for cannabis testing will be significant, and we are excited to partner with Don and his team to pursue this opportunity in Humboldt County.”
Ashley is contributing roughly $2 million to build and equip the lab with instrumentation, while Digipath Labs will manage and supervise operations at the lab. According to the press release, Digipath will provide a non-exclusive license to use its intellectual property for the operation of the lab. Digipath Labs will retain rights over all the scientific data generated in the lab.
According to Cindy Orser, PhD., chief science officer at Digipath, that data will be put to good use. “Digipath Labs has developed an algorithm for use in strain authentication based largely on terpene profiling from our testing lab in Nevada and we are eager to further test our hypothesis with an expanded dataset from cannabis grown in Northern California,” says Orser.
While testing labs are primarily seen as safeguards for public health and safety, using data to correctly identify strains is a relatively new concept. “Digipath Labs is all about public health and safety through testing for adulterants,” says Orser. “Another component to quality is having confidence in product authenticity at the dispensary level. Not only is the consumer buying quality assured products but truth in advertising when it comes to strain nomenclature.”
Denkin says they were proactive in working toward getting the license early on. “Our partners have been dealing with the local regulators while we have been providing the proper SOP’s for the local government in order to receive the proper licensure in the area,” says Denkin. Taking their experience from Nevada to California, Orser says they have been asked to present to the California Toxicology Association on their experience with cannabis testing in the highly regulated marketplace of Nevada.
The laboratory in Humboldt is going to be part of a “cannabis industrial park,” alongside an R&D facility, oils/concentrate manufacturing center, health and wellness center, distribution and processing facility, tissue culture nursery, hemp clothing outlet, and coffee bistro, according to the press release.
Looking forward to growing their business, Denkin says they hope to launch a lab in Southern California. “We do expect to have a larger footprint in California because of the size of the market and are looking for locations in Southern California as well,” says Denkin. When asked about any new plans to expand elsewhere, Denkin says they’ll let us know. “We are continuing with our business plan and actively seeking the right mergers and acquisitions. Stay tuned.”
According to a press release issued on Friday, September 22nd, the Colorado Department of Public Health and Environment (CDPHE), along with the Colorado Department of Revenue (DOR) and the Colorado Department of Agriculture (CDA), issued a public health and safety advisory for cannabis products tainted with pesticide residue.
The advisory was issued after the detection of pesticide residues on retail cannabis plant material and products with cannabis grown by RK Enterprises LTD, doing business as Rocky Mountain Remedies. The CDA confirmed that they detected the pesticide, Avermectin, an insecticide with a relatively high acute toxicity.
When pesticides like this are not on the list approved for use in cannabis cultivation, it is considered an off-label use. According to the press release, some of the products affected include flower, trim, concentrates and infused-products.
Consumers are advised to look at the label of their products and check to see if it matches the license number 403R-00180 and harvest batch numbers r206goldenkush9.11.17 and m206larryog9.11.17. Consumers are told to either dispose of the product properly or bring it back to the retail store where they purchased it.
As of early September, Canopy and Spektrum also announced their next strategic European move. They have just entered into a supply license agreement with Alcaliber, S.A., a leading Spanish pharmaceutical company. Alcaliber specializes in research, as well as the development, breeding and preparation of plant-based and other raw materials into narcotic medicine. More significantly, it is already a leading company in the global pharmaceutical and narcotic space.
According to Bruce Linton, chairman and chief executive officer of Canopy Growth, the partnership opens a lot of doors. “This agreement gives us additional resources to aggressively enter the European market where federally permitted by law, while we continue to work to establish our own complimentary production footprint for cannabis cultivation, value-add oil extraction and Softgel production in the European Union,” says Linton.
Alcaliber is one of the largest producers of morphine in the world (27% of global production) and supplies 18% of its codeine. Cannabis is also considered a narcotic drug in Europe. This kind of track record is exactly what governments are looking for as they figure out how to integrate cannabinoids as medical products into existing pharmaceutical production and distribution. They are equally excited about the possibilities this partnership brings, according to Jose Antonio de la Puente, chief executive officer of Alcaliber. “There is a clear demand for pharmaceutical cannabis produced in accordance with pharmaceutical standards and the expertise we have developed manufacturing narcotic derivatives for over 40 years,” says de la Puente.
The agreement is also the first of its kind between a Canadian cannabis company and a separate, established, international pharmaceutical company. The fact that Alcaliber is located in Spain (albeit Madrid and not Barcelona) makes this new alliance even more interesting, and for several reasons. Not just in Europe or even Canada for that matter.
In the EU? GW Pharmaceuticals, the only other existing pharmaceutical manufacturer and grower of cannabis in Europe, and based in the UK, just got major European if not global competition.
And then of course, there is what is going on Down Under. Australian and Tasmanian companies moving into the game now (with pharma connections, background in opioids and a global footprint) as the medical market in Australia begins to take shape, are about to go head to head with the Canadian-Spanish-German alliance now forming on the other side of the world.
Cross-Continental Plays Are Now Forming
Just as in the U.S., Europe is turning out to be literally a state-by-state chess game of legalization, regulation and supply. Unlike the U.S., however, European countries are bound by both European law and in some cases, sub-regional agreements – like what exists in the so-called Schengen States.
However, even here, the new world is graduating into federal and regional law. And how that will play out in Europe, where the focus is still largely on medical use, is going to be interesting.
What does this mean for Canada’s largest LP? A strong, multi-country presence in the medical cannabis space that, strategically, is par to none other. There are other Canadian LPs who are planning production facilities in other EU countries of course. And some Canadian companies who appear to see Europe as one giant export market. Germany is just one of them. However, the German-Spanish connection is interesting for several reasons: The two most interesting markets globally right now from both a strictly medical perspective with a clear pathway to much broader acceptance as it transitions into some kind of recreational reform, are Spain and Germany. While the former has not signed up for full-boat medical acceptance, the recent independent assertion by the Catalonian government that they would formalize the cannabis club system is seen here as one more step towards the inevitable. So are ongoing and significant Spanish medical cannabis trials.
This move also gives Canopy and Spektrum something else: access to much cheaper Spanish labour and production. This means that no matter where they grow their crops in Europe, or process them, the company now has a two-country supply system for a multi-country medical market that is just waking up. And that is highly valuable right now.
It gives Canopy direct market entry into several European states, with federally approved, medical grade cannabis and medical products. Those who are coming to the rest of Europe from a Spanish base only, will not at this juncture meet strict medical growing requirements for the German market for starters. On the Spanish side of things, this also means that cannabis clubs might be pressured to stop growing their own (at least outside of Catalonia) and rely on more corporate entities to actually grow and process the plant.
What Does This Mean For Euro Industry Development?
Canopy, strategically, has been at the forefront of interesting strategic plays in the global industry for at least the last 18 months to 2 years. They have eschewed the American market (unlike other Canadian competitors) in lieu of other game elsewhere. However their current expansion strategy, geolocationally, has clearly also been at least 12 to 18 months ahead of just about everyone else.
The cross-country chessboard game is also something that other Auslander (foreign or international) companies are clearly trying to play, particularly in Europe. This is true of both actual cannabis production and distribution entities as much as tech. The hop-scotching of both Leafly and Weedmaps across the continent in search of a business strategy that makes sense is just another face of this. Advertising rules in Europe, including online, and especially for cannabis, are a lot different from say, California state law.
However what Canopy appears to be doing is establishing both a brand and production presence in a way that guarantees not only European entry, but potentially dominance in the medical market as the market here continues to expand and open up.
What they are also doing with this announcement is telling the German government, for one, that they can supply patients in the EU with EU-sourced product, even if not grown or produced in Germany itself. This alone will help keep prices down as German cannabis production gets underway over the next several years.
It will also help Canopy deal with what is expected to be at least supply pressure as of next year as the Canadian recreational market gets underway. There is a very good chance that Spanish grown cannabis might end up not only in the rest of Europe but will also be shipped back to Canada if the supply problems there are severe enough.
Whatever the end result, this is an interesting alliance, and coming at an interesting time for not only the German cannabis industry, but a regional market as well. And further, it is also clearly a play with not only hemispheric implications but global ones.
Maintaining an environment that supports cultivation and keeps plants healthy is not an easy task. In cannabis growing, there are a variety of factors that greenhouse managers and personnel must monitor to ensure that their plants are in a healthy environment that fosters growth and development. Temperature, humidity, lighting and CO2 levels are a few of the conditions that need to be tailored to each cannabis greenhouse operation. However, it can be difficult to constantly monitor the status of your equipment and the greenhouse environment, especially after hours or during the off-season.
A remote monitoring system that’s properly selected and installed can help greenhouse managers keep their cannabis plants healthy, multiply their yields and increase return on investment. This type of system also helps operators identify patterns and trends in environmental conditions and get insight into larger issues that can prevent problems before they arise.
Here are some tips on key conditions to monitor and what you need to consider when selecting a monitoring system for your cannabis greenhouse operation:
Temperature plays a crucial role in any cannabis grow operation. The climate in your greenhouse must be warm enough to nurture photosynthesis and the growth of cannabis plants. Setting the incorrect temperature will significantly impact the potential yield of the plant and the rate at which it develops. A temperature too low will slow the growth of the cannabis, but too hot can lead to heat stress for your plants. The ideal temperature for a standard greenhouse is between 70 and 80 degrees Fahrenheit. However, depending on the stage of plant and desired growth densities, the temperature of the greenhouse needs to be adjusted accordingly.
Humidity directly affects plant photosynthesis and transpiration, so controlling humidity is vital in greenhouse growing. The ideal relative humidity (RH) for cannabis growth is around 60%. A low humidity level can cause water to evaporate too quickly for photosynthesis, while a humidity level that is too high can cause poor growth and possible mold and fungal disease. Monitoring the moisture content in the air of your greenhouse will help the plants during the transpiration process, increasing absorption of nutrients and overall health of the cannabis.
Your cannabis may be getting an abundance of natural light during the summer months, but maintaining adequate sunlight during the winter months can be a challenge. As a solution to this, many greenhouse managers equip their facilities with additional lights to supplement natural light during off-seasons or off-hours. To achieve the best possible yield, a cannabis plant in the budding stage should receive twelve hours of light each day, while other stages could require additional lighting. For example, the growth stage could require your cannabis to be exposed to sunlight for up to eighteen hours a day.
Like any other plant, cannabis requires CO2 to breathe. Greenhouse managers must set and monitor the CO2 levels in their facility to make sure that there is an adequate amount for the plants to develop, grow and be healthy. The amount of carbon dioxide required for your cannabis depends of the size of the facility and the amount of light the plants are receiving. However, a standard grow area for cannabis can maintain a CO2 range from 1000 to 1500 parts per million (PPM). A level below that threshold can result in slower growth of the plants, while a level above would lead to unused and wasted CO2.
Irrigation and Soil Moisture
One way to ensure a good yield from your cannabis is to water it regularly and monitor your soil moisture. Overwatering your plants can have the same effect, if not worse, than letting the soil become too dry. Plants’ roots need oxygen to survive, unlike leaves that breathe CO2, and when the soil is waterlogged the roots can’t provide their function. The lack of oxygen interferes with the roots’ nutrient uptake and photosynthesis causing the cannabis plant to wilt. The exact moisture content of the soil depends on the size of your greenhouse, temperature and humidity. Whether you hand water or are using a drip irrigation system, being aware of your soil moisture is vital to the long-term health of your cannabis.
Your greenhouse environment should mimic the ideal conditions in which cannabis plants flourish. With an indoor facility, you have the ability to control air circulation by venting hot air out and blowing fresh air in. Creating a circulation of air inside your greenhouse will increase your cannabis plant’s growth speed and yield. Additionally, an exhaust system helps control the temperature and humidity, while also preventing the invasion of mold and pests that thrive in hot, stagnant air.
When growing something of value, like cannabis, there will always be a threat of intruders. Whether your greenhouse is in a populated area or around hungry wildlife, any intruder could be detrimental to your overall yields and profit. Remote monitoring systems can give you peace of mind and instantly alert you when there is an unwanted presence in your greenhouse.
Knowing all the possible threats to your cannabis greenhouse helps you evaluate your specific needs, and ultimately identify the proper remote monitoring system.
Selecting the Right Monitoring System
Other factors to consider when choosing a monitoring system right for your operation include:
Base unit and sensors
Wireless or hardwired sensors
Communications to your site (Phone, cellular, Wi-Fi, etc.)
Programming and status checks
Return on investment
Base Units and Sensors
Each condition in your greenhouse that you want to monitor requires its own input on the base unit of the monitoring system. You must match your needs with the number of inputs available. A good fit for a smaller cannabis greenhouse may be a lower-cost, non-expandable monitoring system. However, larger facilities have many monitoring points and more people to alert when there’s a problem. If your cannabis operation is poised for growth, purchasing an expandable system could add value to the initial purchase because you wouldn’t have to replace your entire system in the future.
Your monitoring system should also have an internal rechargeable battery backup to ensure continuous monitoring and alerts in the event of a power outage. It is also recommended to have each base unit in a sheltered enclosure to protect it from moisture, dirt and other hazards.
Placement of sensors is also crucial. For example, temperature sensors in your greenhouse should be placed throughout the facility. They should be next to your thermostat and in the center of your greenhouse, preferably away from direct sunlight.
Wireless or Hardwired Sensors
Remote monitoring systems offer the option to have sensors hardwired directly to the base unit or sensors wirelessly connected. A hardwired monitoring system connects the sensors to the base device with wires. Generally, trenching long distances for wires is time consuming and costly. So alternatively, a wireless system uses built-in radio transmitters to communicate with the base unit. Some monitoring systems can accommodate a combination of hardwired and wireless sensors.
Communications to Your Site
Monitoring devices that use cellular communications must be registered on a wireless network (like Verizon or AT&T) before you can send or receive messages. Because cellular devices perform all communications over a wireless network, it is important that there be sufficient signal strength at the greenhouse. It is a good idea to check the signal quality in the area before purchasing a cellular product. If the cellular network has less than desirable coverage, it is possible to install an external antenna to help increase cellular signal.
When monitoring systems identify a change in status, they immediately send alerts to people on the contact list. If you don’t want all of your personnel to receive notifications at the same time, certain devices can be programmed to send alerts in a tiered fashion. It is important to consider the reach of the communications, so that you’ll be notified regardless of your locations. Multiple communications methods like phone, email and text provide extra assurance that you’ll get the alert. Also, note of the number of people the system can reach and if the system automatically cycles through the contact list until someone responds. Make sure the system allows for flexible scheduling so that it doesn’t send alarms to off-duty personnel.
Programming and Status Check
If you’re responsible for maintaining a commercial greenhouse facility, you want a system that will provide real-time status of all monitored conditions on demand. There are a few different ways to access your sensor readings. Options include calling to check status, viewing a web page, either on a local network or on the cloud, or accessing the information via an app on your mobile device. With a cloud-based system, the devices supervise themselves. This means if the internet or cellular connection goes down, the device will send an alarm to alert the appropriate personnel.
If you don’t select a cloud-based system, you will be limited to logging in through a local area network, which will allow you to make programming changes, access status conditions and review data logs. If internet connectivity is not available at your location, you will want to choose a cellular or phone system rather than Ethernet-based option.
Data history is valuable in identifying patterns and trends in your cannabis greenhouse conditions. Manually monitoring and recording environmental parameters takes a significant amount of personnel time and detracts from other important workplace demands. However, many monitoring systems automatically save information, recording tens of thousands of data points, dates and times. Cloud-based logging provides an unlimited number of records for users to view, graph, print and export data trends.
Analyzing data samples may lend insight to larger issues and prevent problems before they arise. For example, if the data log shows power fluctuations occurring at a regular time, it could be indicative of a more serious problem. Or, if the data shows signs of a ventilation fan or supplementary lighting beginning to malfunction, they can be repaired or replaced before total failure occurs.
Return On Investment
When deciding how much you should pay for a remote monitoring system, tally up the entire cost, fully installed with additional peripherals and sensors and any labor fees for installation. Then consider the value of your cannabis plant inventory and greenhouse equipment. Finally, factor in the cost of downtime, should an environmental event shut down your operation for a period of time.
Choosing the right greenhouse monitoring system and sensors could mean the difference between life and death for your cannabis plants. Understanding the conditions you need to watch and monitoring systems’ capabilities are they best way to protect your investment.
According to a press release yesterday sent out by the National Hemp Association (NHA), on Wednesday, June 28th, Board Chairman Geoff Whaling met with senior U.S. Department of Agriculture staff, along with Erica McBride from the Pennsylvania Industrial Hemp Council. The press release says this is the first time that Agricultural Secretary Perdue has had his staff meet with the hemp industry. “The meeting reaffirmed critical elements of the working relationship that the hemp industry has established with the USDA since the enactment of Sec. 7606 of the 2014 Farm Bill,” reads the press release put out by the NHA.
The press release says the USDA will support hemp pilot projects, considering grant and loan applications and other means of funding under the USDA and NIFA. “All hemp industry participants are encouraged to participate in these funding opportunities,” says Whaling. “USDA confirmed that nine Industrial Hemp funding requests to NIFA are being processed and that USDA has encouraged those who submitted previous requests to resubmit them.”
“USDA also offered to provide a quick response to any Secretary or Commissioner of Agriculture who is looking for clarification on either the Farm Bill or SOP, which may be preventing the States that have enacted enabling Industrial Hemp legislation from advancing research,” says Whaling.
A big driver of the meeting was the support of the Industrial Hemp Farming Act of 2018 on behalf of the NHA. That bill, which Congressman James Comer (R-KY) plans on introducing in July, would essentially remove hemp from the Controlled Substances Act, allowing industrial cultivation of the plant. It also would set a THC limit and give states the power to regulate their own hemp industries.
“There is new leadership in the USDA, on the Hill and within our industry,” said Whaling. “I am confident that this group will advance our industry to a level never before achieved.”
According to the Independent, Prime Minister Alexis Tsipras announced last week that Greece will legalize medical cannabis, allowing doctors to write prescriptions for it. “From now on, the country is turning its page, as Greece is now included in countries where the delivery of medical cannabis to patients in need is legal,” says Prime Minister Tsipras at a press conference.
Catalonia, an autonomous region in Spain, legalized consumption of recreational cannabis and cannabis clubs last week. The government voted in favor of the measure with wide support after a 67,500-signature petition brought the debate to the center stage.
According to the Independent, the rules seem relatively restrictive, with measures in place to prevent the capital of Catalonia, Barcelona, from turning into a cannabis tourism capital, such as Amsterdam. One of those rules requires a waiting period for new members of clubs before they can purchase and consume cannabis. However before this measure passed the vote, cannabis clubs were in a legal gray area, with fines for public consumption. These European markets could present excellent opportunities for cannabis companies, which could cause other EU countries make the plunge into legal cannabis.
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.
The Organic Cannabis Association and Ethical Cannabis Alliance announced today they are merging into one organization, the Cannabis Certification Council (CCC), according to a press release. The new third-party certifications include “Organically Grown” and “Fairly Produced”, granting producers a seal for marketing if they achieve the certifications.
According to Ashley Preece of the Ethical Cannabis Alliance, now executive director at CCC, they plan on starting with the “Organically Grown” certification as first certification to market. “We are launching with Organically which will include robust labor standards as well as standards that go beyond [USDA] Organic,” says Preece. “The USDA Organic standard is watered down and we want to expand on proper horticulture practices so it relates directly to cannabis producers.” The process of designing that certification involves using that USDA Organic certification as a building block to draw from but not directly adopt.
“We will start by pulling from Organic and Fair Trade standards, then we will have a technical advisory committee (TAC), made up of multi-stakeholder agricultural industry and cannabis industry professionals to give input and adjust the standard accordingly,” says Preece. “From there we will have a pilot program, engaging with producers abiding by the standards’ requirements. After the pilot phase, we make final adjustments before bringing it to market.” In order to make sure their certification works across the board, Preece says they are engaging with stakeholders around the country and eventually globally. “We need to engage each different community to make sure this is applicable on a national level.” Preece also says they plan staying abreast of other standards, such as ASTM International’s, but those are geared more towards production safety. “We are looking towards more robust Organic and Fair Trade standards, and ‘cannabinizing’ them,” says Preece.
David Bronner, a prominent advocate of drug policy reform and CEO of Dr. Bronner’s, a top-selling soap brand in the US market place, will be providing seed funding and a matching grant to the CCC. “We are committed to making socially and environmentally responsible products of the highest value, and we are excited for the CCC to begin driving that ethos in the cannabis industry,” says Bronner. “The Cannabis Certification Council (CCC), with its unique mission, is a perfect vessel for us to support our values in the cannabis space.”
Preece says the “Fairly Produced” labor certification is going to be based off of Fair Trade practices. “That will include living wages per community and taking options of ownership into consideration, including different business models where employees might have shares or partial ownership,” says Preece. “As we know, this industry has come from the illicit market, where we saw a lot of inappropriate working environments, gender relations and pay schedules. So we want to ensure that workers have contracts in place, they are treated fairly just as any other industry and we want to mitigate any strange encounters that might have seeped into this regulated market.” Founding board members include Laura Rivero of Yerba Buena Farms; Amy Andrle of L’Eagle Services Denver; Nick Richards of Dill and Dill and Vicente Sederberg; and Ben Gelt of Par, with Ashley Preece as executive director. “This is a huge step for the cannabis industry,” says Preece. “Our collaboration reflects the priority of the mission ingrained in both parties, and together we will immediately be greater than the sum of our parts.”
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.
