Last week at the MJBizCon, a major cannabis industry event held annually in Las Vegas, urban-gro launched the first technology line for cannabis growers utilizing Internet-of-Things (IoT). urban-gro, a cultivation technology company for commercial-scale growers, announced the launch of announced Soleil® Technologies, an integrated portfolio of hardware, software, and services that uses IoT.
“The solution suite includes per-plant sensing, environmental monitoring, machine diagnostics, fertigation management, lighting controls, inventory management, and seed-to-sale tracking,” reads the press release. IoT is essentially a network of devices embedded with sensors and software that allow the devices to connect and exchange data. IoT devices are used extensively in the food industry, including for integrated pest management, restaurant food safety and management and tracking product conditions such as temperature and humidity throughout the supply chain, among other uses.
Soleil consists of three primary lines:
Soleil 360 is the cloud-based software-as-a-service (SASS) platform that integrates all Soleil solutions.
Soleil Sense is the brand for all of urban-gro’s low-power wireless sensors that deliver data with the scale, precision and resolution needed for analytics and machine learning.
Soleil Controls is urban-gro’s product set for climate and irrigation controls, lighting systems, and other focused controls.
The core, low-power sensor that makes this unique was licensed from Edyza, a wireless innovator that specializes in low-power wireless grids that scale. urban-gro then developed on top of that sensor, including its cloud-based management, analytics, what the sensors detect and cover, etc., to make it ideal for cannabis growers.
According to Brad Nattrass, urban-gro’s chief executive officer, finding an IoT solution that can easily scale was a key goal for their business. “When evaluating the most advanced market-ready sensor technology available, it was crucial that we deliver a solution that can easily scale to thousands of sensors in order to satisfy the needs of large-scale commercial cultivators,” says Nattrass. “The introduction of Soleil demonstrates urban-gro’s commitment to going beyond simply supplying equipment, to truly serving our clients as an ongoing technological innovator and advisor, enabling cultivators to leverage today’s more advanced technologies to rise above the competition.”
“Cultivators will be able to monitor substrate moisture and EC (electrical conductivity) levels on a per plant basis, as well as track key environmental metrics like temperature, humidity, air movement, and probability of infestation,” reads the press release. “With multiple device options, cultivators can choose between several deployment options.” With the data hosted on the cloud, users can access it through web browsers, Android and iOS devices.
According to Jay Nichols, a representative of urban-gro, they have hired (and is hiring) code developers, product developers, etc. in order to expand this unit. Plant sensors are just one piece of the system, with the goal to automate the entire cultivation process, including controlling lights, pest management, irrigation and fertigation. They say it will be available in late Q1/early Q2.
Poland has now legalized cannabis for medical purposes.
That said, it will be some time before patients have access to the drug. While Poles can now technically access medical pot, the scheme approved by the Polish Parliament that went into effect on November 1st is regressive, to say the least. Certainly compared with even other countries in Europe that are now finally admitting that cannabis is a drug with medical efficacy, the Polish experiment looks “old-fashioned.”
What Does Medical Cannabis Reform Look Like in Poland?
Like most conservative countries, Poland is sticking with a highly restrictive approach that still puts patients in the hot seat. In addition to getting a doctor’s prescription, the chronically ill must be approved by a state authority – a regional pharmaceutical inspector. They must get a license first, in other words. They must then find about $500 a month to pay for cannabis. To put this in perspective, that is roughly the total amount such patients get from the state to live on each month.

The multiple steps mean that only patients with financial resources– and an illness which is chronic but still allows them to negotiate the many government hurdles, including cost –will now be able to access medical cannabis. Unlike Germany which makes no such distinctions, Polish law now recognizes the drug as an effective form of treatment only for chronic pain, chemo-induced nausea, MS and drug-resistant epilepsy.
The heavily amended legislation also outlaws home growing. And while 90% of pharmacies will be able to dispense the drug, this is again, a technicality. Where will the pharmacies get the cannabis in the first place?
So the question remains: will this step really mean reform? There is no medical cultivation planned. And no companies (yet) have been licensed to import the drug.
This is what is clear. Much like the conversation in Georgia and other southern American states several years ago, legislators are bowing to popular demand if not scientific evidence, to legalize medical use. But patients still cannot get it – even if they jump through all the hoops.
In Poland, patients who cannot find legal cannabis in the country (which is all of them at this point) now do have the right to travel to other EU countries in search of medicine. But the unanswered question in all of this is still present. How, exactly is this supposed to work? Patients must come up with the money to pay for their medical cannabis (at local prices) plus regular transportation costs. Then they must pay sky high fees to access local doctors (if they can find them) at “retail cost” uncovered by any insurance.
The issue of countries legalizing cannabis on paper, but not in action, is a problem now facing legalization advocates in the EUThe most obvious route for Polish patients with resources and the ability to travel is Germany. The catch? Medical cannabis costs Just on this front, the idea of regular country hopping for script refills – even if “just” across the border – is ludicrous. And who protect such patients legally if caught at the border, with a three month supply?
Poland, in other words, has adopted something very similar to Georgia’s regulations circa 2015. Medical cannabis is now technically legal but still inaccessible because of cost and logistics. Reform, Polish-style, appears to actually just be more window-dressing.
And while it is an obvious step for the country to start issuing import licenses to Canadian, Israeli and Australian exporters, how long will that take?
The Next Step Of Reform – Unfettered Patient Access
While things are still bad in Poland, right across the border in Germany where presumably Polish patients could theoretically buy their medical cannabis, all is still not copacetic. Even for the “locals.” Germany’s situation remains dire. But even before legalization in March, Germany was importing bud cannabis from Holland and began a trickle of imports last summer from Canada. That trickle has now expanded considerably with new import licences this year. And presumably, although nobody is sure, there will be some kind of domestic cultivation by 2019.
At Deutsche Hanfverband’s Cannabis Normal activist’s conference in Berlin held on the same weekend as Poland decided to legalize medical cannabis, a Gen X patient expressed his frustration with the situation of legalization in general. Oliver Waack-Jurgensen is now suing his German public insurer. He expects to wait another year and a half before he wins. In the meantime, he is organizing other patients. “They [political representatives] are bowing to political expediency but completely ignoring patient needs,” says Waack-Jurgensen. “How long is this conversation going to take? I am tired of it. Really, really tired of this.”
The issue of countries legalizing cannabis on paper, but not in action, is a problem now facing legalization advocates in the EU and elsewhere who have achieved legislative victories, but still realize this is an unfinished battle. Germany is the only country in Europe with a federal mandate to cover the drug under insurance (for Germans only). And that process is taking time to implement.But even in Germany, patients are having to sue their insurance companies
Germany, Italy and Turkey are also the only countries in Europe as of now with any plans to grow the drug domestically under a federally mandated regulation scheme. Import from Holland, Canada and even Australia appears to be the next step in delaying full and unfettered reform in Europe. See Croatia, Slovenia and Bosnia. How Spanish or Portuguese-grown cannabis will play into this discussion is also an open question mark. Asking Polish patients suffering from cancer to “commute” to Portugal is also clearly unfeasible.
Unlike the United States, however, European countries do have public healthcare systems, which are supposed to cover the majority of the population. What gives? And what is likely to happen?
A Brewing Battle At The EU Human Rights Court?
While the Polish decision to “legalize” medical use is a step in the right direction, there is still a long way to go. If the idea is to halt the black market trade, giving patients real access is a good idea. But even in Germany, patients are having to sue their insurance companies. And are now doing so in large numbers. In a region where lawsuits are much less common than the U.S., this is shocking enough.
But the situation is so widespread and likely to continue for some time, that class action lawsuits – and on the basis of human rights violations over lack of access to a life-saving drug – may finally come to the continent and at an EU (international) level court.
Patients are literally dying in the meantime. And those who aren’t are joining the calls for hunger strikes and other direct civil action. Sound far-fetched? There is legal precedent. See Mexico.
And while Poland may or may not be the trigger for this kind of concerted legal action, this idea is clearly gathering steam in advocacy circles across Europe.
I recently attended the CannaGrow Expo held in Denver, Colorado. It was a fantastic event, per usual, and I was pleasantly surprised to see a number of presentations by industry experts where the central themes were sustainability and environmental stewardship. I was particularly struck by Adam Maher’s presentation, where he discussed the merits of micro grid technologies and the ease in which they can be coupled with renewable energy modalities, such as solar. His sentiments really resonated with me, particularly with respect to the long-term implications of cannabis cultivation sweeping across North America.
Considering that cannabis represents the new frontier of modern medicine and its societal acceptance is rapidly spreading, there is a growing impetus for cannabis professionals to implement technologies that will enhance the sustainability of their operations. These pertain to, but are not limited to, power generation and lighting, both of which are integral components to any indoor cannabis cultivation facility. Not only can the utilization of energy efficient technologies (i.e., solar panels and LED lights) help our planet that is struggling mightily to neutralize the influences of anthropogenic climate change, but it can also add value to the bottom line. That’s right: environmental stewardship, product quality and financial success are not mutually exclusive in the cannabis industry. For example, the utilization of solar panels and/or a micro grid can have a relatively rapid payback (<6 years), while the hardware itself adds inherent value to any cannabis property/operation. This is particularly relevant in an emerging market where acquisitions are common and the management of asset value is a harbinger of success. Secondarily, the use of LED lighting technologies to produce ultra-premium cannabis is another piece of low-hanging fruit that can be picked to add value. For example, 1st and 2nd place in Arizona’s 2017 ERRL Cup were awarded to flower that was grown under LED lights designed by the Tall Trees LED Company, where the total cannabinoid levels exceeded 32% and a wide variety of terpenes were detected. These results, coupled with the fact that LED lights can provide full spectrum light that requires less energy and produces less heat than HPS lights, make the adoption of LED lights a simple choice for the environmentally conscious and financially savvy operator.
As we continue to move towards more states becoming cannabis powerhouses, and a potential federal rescheduling, the industry must continue pushing the operational equilibrium towards more resourceful technologies. Of course there is always going to be a perceived activation energy or threshold that must be transcended before the adoption of new technologies can be successfully accomplished with confidence. This is completely normal and is usually associated with the initial capital that is required to acquire such technologies, and/or fears that such an investment won’t bear fruit. However, there is currently enough data to indicate that technologies like solar panels and LED lights are a smart financial choice for any cultivation facility where there is sunlight and electrical outlets.
In summary, I would strongly encourage any operator to evaluate the sustainability and environmental stewardship of their business, especially if they anticipate spreading the holistic gospel of cannabis medicine for many years to come. You are already doing a tremendous service for those who depend on cannabis medicine and now is the time to continue your noble pursuit while taking care of Mother Earth and paying it forward to our subsequent generations.
Germany is proceeding down the path to officially grow its own medical cannabis crops. Medical use became legal this year, along with a federal mandate for cheap access. That means that public health insurance companies, which cover 90% of Germans, are now firmly on the hook if not front line of the cannabis efficacy issue. As such, Germany’s medical market is potentially one of the most lucrative cannabis markets in the world, with a total dollar amount to at least challenge, if not rival, even California’s recreational market. Some say Canada’s too.
However, before “home grow” enthusiasts get too excited, this legislative move was an attempt to stymie everything but commercial, albeit medical production. Not to mention shut off the recreational discussion for at least another four years.
How successful that foray into legalization will be – especially given the chronic shortages now facing patients – are an open question. Not to mention other infrastructural issues – like doctor unfamiliarity with or resistance to prescribing cannabinoids. Or the public insurers’ so-far reluctance to cover it even though now federally mandated to do so.
Regardless, Germany decided to legalize medical use in 2017 and further to begin a sanctioned domestic cultivation for this market. The decision in the Bundestag to legalize the drug was unanimous. And the idea to follow UN regulations to establish this vertical is cautiously conservative but defendable. Very predictably German in other words.
Since then, however, the path has been far from smooth. Much less efficient.
Trouble in Germany’s Medical Cannabis Paradise
In April the government released its tender bid. And no matter how exciting it was to be in the middle of an industry who finally saw a crack of light, there were also clouds to this silver lining that promised early and frequent thunderstorms on the horizon.
By the time the tender bid application was due in June, it was already clear who the top firms were likely to beIn fact, by the end of the ICBC conference, which held its first annual gathering in Berlin at the same time the bid tender was announced, the controversy was already bubbling. The requirements of the bid, for a laughably small amount of cannabis (2,000 kg), mandated experience producing high qualities of medical marijuana in a federally legitimate market. By definition that excluded all German hopefuls, and set up Canada and Holland as the only countries who could provide such experience, capital and backlog of crop as the growing gets started.
The grumbling from Germans started then.
However, so did an amazingly public race to gain access to the German market directly – by acquisition or capital expenditures that are not refundable easily (like real estate or even buyouts). The common theme? They were large amounts of money being spent, and made by major Canadian Licensed Producers who had the right qualifications to meet the standards of the bid. In fact, by the time the tender bid application was due in June, it was already clear who the top firms were likely to be. They were the only ones who qualified under the judging qualifications.
And while nobody would commit publicly, news of the final decision was expected by August. Several Canadian LPs even issued press releases stating that they were finalists in the bid. But still no news was forthcoming about the official list.
Delay, Delay and More Delay
A month later, as of September, and there was still no official pronouncement. Nor was anybody talking. BfArM, the regulatory agency that is supervising this rollout as well as the regulation of all narcotic drugs (sort of like a German version of the FDA) has been issuing non-statement statements since the late summer. Aurora, however, one of the top contenders for cultivation here, was quietly issued an ex-im license by both Canadian and German authorities. Publicly, this has been described as an effort to help stem the now chronic cannabis shortage facing patients who attempt to go through legitimate, prescribed channels. On the German side, intriguingly, this appears to be a provisional license. Privately, some wondered if this was the beginning of a backdoor approval process for the top scoring bid applicants for cultivation. Although why that might be remains unclear.
Whispered rumours by industry sources that wish to remain anonymous, have suggested that the entire bid is still hanging in jeopardy. Late in the month, rumours began to fly that there were now lawsuits against the bid process. Nobody had much detail. Not to mention specifics. But CannabisIndustryJournal can now confirm in fact that there have been two lawsuits (so far).
The summary of the complaints? It appears that two parties, filing with the “Bundeskartellamt” (or regulatory office focusing on monopolies and unfair business practices) did not think the bid process or scoring system was fair. And both parties also lost.
But as of mid-October, there is still no public decision on the bids. What gives?
Whispered rumours by industry sources that wish to remain anonymous, have suggested that the entire bid is still hanging in jeopardy. Even though the plaintiffs failed, some have suggested that the German government might force a complete redo. Others hint that it will likely be slightly revised to be more inclusive but the regulatory standards must remain. If a redo is in the cards, will the German government decide to increase the total amount of yearly cannabis to be delivered? At this point, it is only calling for 2,000 kg per year by 2019. And that, as everyone knows, is far too little for a market that is exploding no matter the many other obstacles, like insurance companies refusing to compensate patients.
What Is Behind The Continued Delays?
There are several theories circulating the higher levels of the cannabis industry internationally right now even if no one is willing to be quoted. The first is that the total number of successful applicants, including the recent litigants, will be slightly expanded, but stay more or less the same. There is a high standard here for the import of medical cannabis that the Germans intend on duplicating domestically.
The Comprehensive Economic Trade Agreement (CETA – the often controversial free trade alliance between Europe and Canada) is still in the final stages of approval.The second is that the German government will take its time on announcing the final winners and just open the doors to more imported product. This will not be popular with German insurers, who are on the hook to pay the difference. However with Tilray now on track to open a processing facility in Portugal and Canopy now aligned with Alcaliber in Spain, cross-continent import might be one option the government is also weighing as a stop-gap provision. Tilray, who publicly denied in the German press that they were participating in the cultivation license during the summer, just issued a press release in October announcing a national distribution deal to pharmacies with a German partner – for cannabis oil.
But then there is another possibility behind the delay. The government might also be waiting for another issue to resolve – one that has nothing to do with cannabis specifically, but in fact is now right in the middle of the discussion.
The Comprehensive Economic Trade Agreement (CETA – the often controversial free trade alliance between Europe and Canada) is still in the final stages of approval. In fact, on September 19, a prominent German politician, Sigmar Gabriel of the Social Democrats (SPD) made a major statement about his party’s willingness to support Germany’s backing of the deal. It might be in fact, that the German government, which is supportive of CETA, got spooked about the cannabis lawsuits as test trials against not cannabis legalization, but a threat to the treaty itself.
Quality control, namely pesticides when it comes to plant matter, and the right of companies to sue governments are two of the most controversial aspects of this trade deal. And both appear to have risen, like old bong smoke, right at the final leg of closing the cannabis cultivation bid.
Will cannabis be seen as a flagship test for the seaworthiness of CETA? On a very interesting level, that answer may be yes. And will CETA in turn create a different discussion about regulatory compliance in an industry that has been, from the beginning of this year, decidedly Canadian-Deutsch? That is also on the table. And of great concern to those who follow the regulatory issues inherent in all. Not to mention, of course, the industry itself.
Conclusions?
Right now, there are none to be had.
However at present, the German bid process is several months behind schedule as Canadian producers themselves face a new wrinkle at home – the regulation of the recreational crop in the provinces.
It is also clear that there are a lot of questions and not a whole lot of answers. Not to mention a timeline when the smoke will clear.
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.
Canopy Growth (based in Ontario, Canada) and its subsidiary, Spektrum Cannabis GmbH (in St. Leon-Rot, Germany) have been making waves all year.
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.
Why?
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.
Cloud-based monitoring system base unit in weatherproof enclosure
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
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 Levels
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.
Lighting
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.
CO2 Levels
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.
Soil moisture sensor
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.
Air Circulation
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.
Greenhouse Security
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.)
Alarm notification
Programming and status checks
Data logging
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.
Alarm Notifications
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 Logging
Sample greenhouse monitoring data log
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.
Final Thoughts
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.
On Monday, August 28th, attendees of the Cannabis Science Conference descended on Portland, Oregon for a week of educational talks, networking and studying the science of cannabis. On Monday, Chalice Farms, an extracts and infused products company, hosted the full-day JCanna Boot Camp focused on a deep dive behind the scenes of a cannabis production facility. The Cannabis Science Conference, hosted by Josh Crossney, founder of JCanna, takes place August 28th to 30th.
Attendees touring an extraction setup
Attendees were split into five groups where they listened to a variety of educational sessions and toured the facility. A track focused on cultivation, led by Autumn Karcey, president of Cultivo, Inc., detailed all things facility design for cannabis cultivation, including an in-depth look at sanitation and safety. For example, Karcey discussed HVAC cleanliness, floor-to-ceiling sanitation and the hazards associated with negative pressure. These principles, while applicable to most cultivating facilities, applies particularly to commercial-scale grows in a pharmaceutical setting.
Sandy Mangan and Tristan DeBona demonstrating the grinding technique for sample prep
During one session, Sandy Mangan, accounts manager at SPEX Sample Prep and Tristan DeBona, sales specialist at SPEX Sample Prep, demonstrated the basics of sample preparation for detecting pesticides in infused products, such as gummies. That required using their GenoGrinder and FreezerMill, which uses liquid nitrogen to make gummies brittle, then pulverizing them to a powder-like substance that is more conducive for a QuEChERS preparation.
Joe Konschnik and Susan Steinike demonstrate the QuEChERS method
Joe Konschnik, business development manager at Restek, Susan Steinike, product-marketing manager at Restek and Justin Steimling, an analytical chemist at Restek, gave a demonstration of a full QuEChERS extraction of a cannabis sample for pesticide analysis, with attendees participating to learn the basics of sample preparation for these types of tests.
Following those were some other notable talks, including a tour of the extraction instruments and equipment at Chalice Farms, a look inside their commercial kitchen and a discussion of edibles and product formulation. Dr. Uma Dhanabalan, founder of Uplifting Health and Wellness, a physician with over 30 years of experience in research and patient care, led a discussion of physician participation, patient education and drug delivery mechanisms.
Amanda Rigdon, Emerald Scientific, showing some complex matrices in cannabis products
Amanda Rigdon, chief technical officer of Emerald Scientific, offered a demonstration of easy and adaptable sample preparation techniques for potency testing of infused product matrices. Rigdon showed attendees of the boot camp how wildly diverse cannabis products are and how challenging it can be for labs to test them.
The JCanna Canna Boot Camp is a good example of an educational event catered to the cannabis industry that offers real, hands-on experience and actionable advice. Before the two-day conference this week, the boot camp provided a bird’s eye view for attendees of the science of cannabis.
According to an article on Reuters, Uruguay’s pharmacies opened for recreational cannabis sales on Wednesday for those over the age of 18. Uruguay beginning recreational sales marks an important milestone as the first country to fully legalize cultivation, sales and recreational use of cannabis.
The country legalized cannabis more than three years ago, but it has taken a while for the government to work out and implement their regulatory framework. Only two companies, Symbiosis and Iccorp, received government licenses for growing, packaging and distribution, according to Reuters.

Consumers are required to register with the government and are only allowed to purchase up to 40 grams of cannabis per month. 5-gram packages are the only products for sale currently at $6.50 a piece. As of now there are only two types of cannabis that consumers can purchase: “Alfa 1”, and indica, and “Beta 1”, a sativa. According to Reuters, neither has a particularly high concentration of THC.
The government says they will carefully monitor production and registrations to prevent diversion and cannabis leaving the country. Only citizens of Uruguay over 18 are permitted to register to buy cannabis. With over 3.4 million people residing in Uruguay, less than 5,000 have registered by Wednesday. All sales must go through a pharmacy, according to the Reuters article.
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.”

“The solution suite includes per-plant sensing, environmental monitoring, machine diagnostics, fertigation management, lighting controls, inventory management, and seed-to-sale tracking,” reads the press release. IoT is essentially a network of devices embedded with sensors and software that allow the devices to connect and exchange data. IoT devices are used extensively in the food industry, including for integrated pest management, restaurant food safety and management and tracking product conditions such as temperature and humidity throughout the supply chain, among other uses.
According to Brad Nattrass, urban-gro’s chief executive officer, finding an IoT solution that can easily scale was a key goal for their business. “When evaluating the most advanced market-ready sensor technology available, it was crucial that we deliver a solution that can easily scale to thousands of sensors in order to satisfy the needs of large-scale commercial cultivators,” says Nattrass. “The introduction of Soleil demonstrates urban-gro’s commitment to going beyond simply supplying equipment, to truly serving our clients as an ongoing technological innovator and advisor, enabling cultivators to leverage today’s more advanced technologies to rise above the competition.”
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.
