You have read the press releases. You may have heard about such ideas at a recent cannabis conference in and around the EU of late. Or you may have encountered new distributors coming into the game with a German presence and a decidedly interesting ex-im plan that sounds a bit, well, off the map.
No matter how geographically creative some of these plans are, the problem is that many of these ideas literally do not make economic sense. Either for the companies themselves (if not their investors), and certainly not for patients. Not to mention, truth be told, the looming price sensitivity issues in the European market that North Americans, for starters, seem to still just be waking up to.
Some Recent Examples….
Yes, exports from Denmark have been much in the news lately (including into both Germany and Poland). Truth be told, however, this makes about as much sense, economically, as importing ice to eskimos. Why? Denmark, for all its looser regulations and less-uptight approach to the cannabis discussion generally, is one of the most expensive labour markets in Europe. Fully automated production plants are one thing, but you can build those in other places too. Especially warmer climates, with lots of sunshine. German production, as it comes online, will also make this idea increasingly ludicrous.
Who on earth got on this bandwagon? It seems that the enthusiasm in the room began when Denmark began to import to Germany (where the disparities in wages in production are not so noticeable). However, lately, several Canadian companies with a Danish footprint have been eying Poland of late.
And on that particular topic – there are many who are doing the math and trying to figure out, as the alternatives get going, if even Canada makes much sense, or will in a few years.
Low Wage Markets With Sunshine Are Hotspots For European Cannabis Production
Like it or not, the European market is extraordinarily price sensitive – namely because it is not “just” consumers called patients picking up the tab but health insurance companies demanding proof of medical efficacy.
That starts, a bit unfortunately, with understanding wage economics across Europe. The warmer the climate, in other words and the further east on the map, wages drop precipitously. That is “good” for an industry looking to produce ever cheaper (but more compliant) product.
It is also good, at least politically, for countries whose elected leaders are being forced to admit that cannabis works, but are less than copacetic about encouraging local production. See Germany for starters, but places like Austria, Poland and most recently France (which has just embarked on a first of its kind medical cannabis trial).
Here, no matter the temporary buzz about Denmark, are the places that cannabis production makes sense:
Portugal: The country is a newcomer in the cannabis discussion this fall, although in truth, the seeds of this reality were sown several seasons ago when Tilray began to build its production plant in the country in 2017. They are far from the only company who has seen the light, and these days, farmers are getting hip to the possibilities. Especially if they are already exporting crops throughout Europe.
Spain: The industry that can afford GMP certification is getting going, but everyone else is stuck in a limbo between pharmaceutical producers and the strange gray market (see the patient clubs in Barcelona). That said, political groups are beginning to discuss cultivation as an economic development tool, if not sustainable food and medication strategies.
Greece: The weather is warm, and the investment climate welcoming. Of all the countries in the EU, Greece has embraced the economic possibilities that cannabis could bring. How that will play out in the next years to come is an intriguing story.
Italy: The southern part of the country in particular is ripe for cannabis investment and it’s full of sunshine. However, as many have noted, organized crime in this part of the world is a bit fierce and starts with the letter M.
Malta: The island is a comer, but does importing cannabis from here really make economic sense? There are trade routes and economic treaties tying the island both to the apparently Brexiting British and Europe. Why not, right? Just remember that along with labour, transportation costs are in the room here too.
And Just Outside The EU…
The country now (sort of) known as North Macedonia and struggling to get into the EU if France would just get out of the way is also going to be a heavyweight in this discussion for years to come. Wages, of course, will increase as part of EU membership, but in general, this country just north of Greece is going to play a highly strategic role in exports throughout Europe.
Core values often get wrapped into buzzwords such as sustainability, locally sourced and organic. In the first part of a series of four articles exploring greenhouses and the environment, we’re going to take a look at indoor vs. outdoor farming in terms of resource management.
Full disclosure; I love the fact that I can eat fresh blueberries in February when my bushes outside are just sticks. Is there a better way to do it than trucking the berries from the farm to a distribution plant to the airport, where they’re flown from the airport to a distribution center, to the grocery store and finally to my kitchen table? That’s a lot of trucking and a lot of energy being wasted for my $3.99 pint of blueberries.The largest generation in the history of the country is demanding more locally grown, sustainable and organic food.
If those same blueberries were grown at a local greenhouse then trucked from the greenhouse directly to the grocery store, that would save diesel fuel and a lot of carbon emissions. People who can only afford to live near a highway, a port or an airport don’t need to ask a pulmonary specialist why their family has a higher rate of COPD than a family who lives on a cul-de-sac in the suburbs.
Fact: 55% of vegetables in the U.S. are grown under cover. The same energy saving principles apply to indoor cannabis and the reasons are consumer driven and producer driven. The largest generation in the history of the country is demanding more locally grown, sustainable and organic food. They want it for themselves and they want it for their kids.
The rapid proliferation of greenhouses over the past ten years is no coincidence. Millennials are forcing changes: organic fruit and vegetables now account for almost 15% of the produce market. A CNN poll last month revealed that 8 of 10 of registered Democrats listed climate change as a “very important” priority for presidential candidates. The issue is not party I.D.; the issue is that a large chunk of Americans are saying they’re worried about the direct and indirect impacts of climate change, such as increased flooding and wildfires.
So how does the consumer side tie into the cannabis industry? Consumers like doing business with companies who share their values. The hard part is balancing consumer values with investor values, which is why many indoor growers are turning to cultivation management platforms to help them satisfy both constituencies. They get the efficiency and they get to show their customers that they are good stewards of their environment. The goal is to catch things before it’s too late to save the plants. If you do that, you save the labor it costs to fix the problem, the labor and the expense of throwing away plants and you reduce pesticide and chemical usage. When that happens, your greenhouse makes more money and shows your customers you care about their values.
The indoor change is happening rapidly because people realize that technology is driving increased revenue while core consumer values are demanding less water waste, fewer pesticides, herbicides and fertilizers.Let’s add some more facts to the indoor-outdoor argument. According to an NCBI study of lettuce growing, “hydroponic lettuce production had an estimated water demand of 20 liters/kg, while conventional lettuce production had an estimated water demand of 250 liters/kg.” Even if the ratio is only 10:1, that’s a huge impact on a precious resource.
Looking at the pesticide issue, people often forget about the direct impact on people who farm. “Rates in the agricultural industry are the highest of any industrial sector and pesticide-related skin conditions represent between 15 and 25% of pesticide illness reports,” a 2016 article in The Journal of Cogent Medicine states. Given the recent reports about the chemicals in Roundup, do we even need to continue the conversation and talk about the effects of fertilizer?
I’ll finish up with a quote from a former grower. “The estimates I saw were in the range of between 25%-40% of produce being lost with outdoor farming while most greenhouse growers operate with a 10% loss ratio.”
The indoor change is happening rapidly because people realize that technology is driving increased revenue while core consumer values are demanding less water waste, fewer pesticides, herbicides and fertilizers. Lastly, most Americans simply have a moral aversion to seeing farms throw away food when so many other people are lined up at food banks.
This is not a discussion of climate change, it’s a discussion of the impact of weather on the agriculture industry. The question for the cannabis & hemp industry, and basically the entire specialty crop industry, is what will be the impact? According to the U.S. National Climate Assessment, “Climate disruptions to agriculture have been increasing and are projected to become more severe over this century.” I’m sure that’s not much of a shock to anyone who owns a farm, orchard or greenhouse.
Every national newspaper for the past two weeks has published at least one article a day about the flooding in the Midwest, while industry newsletters and blogs have contained more in-depth stories. The question is, what can agriculture professionals do to mitigate these problems?
Relying on state and national legislators, especially heading into a presidential election year is likely to be frustrating and unrewarding. Governments are excellent at reacting to disasters and not so good at preventing them. In short, if we depend on government to take the lead it’s going to be a long wait.Instead, many farmers are looking at the future costs of outdoor farming and concluding that it’s simply cheaper, more efficient and manageable to farm indoors.
Instead, many farmers are looking at the future costs of outdoor farming and concluding that it’s simply cheaper, more efficient and manageable to farm indoors. Gone are the days when people grew hemp and cannabis indoors in an effort to hide from the police. Pineapple Express was a funny movie but not realistic in today’s environment.
Today’s hemp and cannabis growers are every bit as tech savvy as any other consumer-oriented business and one could argue that given the age of their customers (Statista puts usage by 18-49-year-olds at 40%), distributors must be even more tech savvy to compete effectively. Some estimates put the current split of cultivation at about one-third indoors/two-thirds outdoors. To date, the indoor focus has been on efficiency, quality and basically waiting for regulators to allow shipping across state lines.
A major driver in the indoors/outdoors equation is that as the weather becomes more unfriendly and unpredictable, VC’s are factoring climate disruption into their financial projections. When corn prices drop because of export tariffs, politicians lift the ban on using Ethanol during the summer months. It’s going to be a while before we see vehicles running on a combination of gasoline and CBD.
Leaving aside the case that can be made for efficiency, quality control and tracking of crops, climate change alone is going to force many growers to reassess whether they want to move indoors. And, it’s certainly going to weigh heavily in the plans of growers who are about to launch a cannabis or hemp business. Recently, one investment banker put it to me this way: greenhouses are the ultimate hedge against the weather.
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.
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.
