The technology portfolio, aimed at larger, commercial-scale growers, is essentially a network of monitors, sensors and controls that give cultivators real-time data on things like temperature, humidity, light, barometric pressure and other key factors. The idea of using IoT and hypersensitive monitoring is not new to horticulture, food or agriculture, but this is certainly a very new development for the cannabis growing space.

According to Brad Nattrass, chief executive officer and co-founder of urban-gro, it’s technology like this that’ll help growers control microclimates, helping them make the minor adjustments needed to ultimately improve yield and quality. “As ROI and optimized yields become increasingly important for commercial cultivators, the need for technologies that deliver rich granular data and real-time insights becomes critical,” says Nattrass. “With the ability to comprehensively sense, monitor, and control the microclimates throughout your facility in real-time, cultivators will be able to make proactive decisions to maximize yields.”

The heat map allows you to find problem microclimates throughout the grow space.

One of the more exciting aspects of this platform is the integration of sensors, and controls with automation. With the system monitoring and controlling fertigation, lighting and climate, it can detect when conditions are not ideal, which gives a cultivator valuable insights for directing pest management or HVAC decisions, according to Dan Droller, vice president of corporate development with urban-gro. “As we add more data, for example, adding alerts for when temperatures falls or humidity spikes can tell a grower to be on the lookout for powdery mildew,” says Droller. “We saw a corner of a bench get hot in the system’s monitoring, based on predefined alerts, which told us a bench fan was broken.” Hooking up a lot of these nodes and sensors with IoT and their platform allows the grower to get real-time monitoring on the entire operation, from anywhere with an Internet connection.

Droller says using more and more sensors creates super high-density data, which translates to being able to see a problem quickly and regroup on the fly. “Cannabis growers need to maintain ideal conditions, usually they do that with a handful of sensors right now,” says Droller. “They get peace of mind based on two or three sensors sending data points back. Our technology scales to the plant and bench level, connecting all of the aggregate data in one automated system.”

In the future, urban-gro is anticipating this will lay the groundwork for using artificial intelligence to learn when controls need to be adjusted based on the monitoring. Droller hopes to see the data from environmental conditions mapped with yield and by strain type, which could allow for ultra-precise breeding based on environmental conditions. “As we add more and more data and develop the platform further, we can deliver some elements of AI in the future, with increased controls and more scientific data,” says Droller.

3 Ways The Cannabis Industry Can Benefit By Adopting IoT Tech

The cannabis industry of the United States is unlike other horticulture markets in the country. It’s younger, less traditional and with roots in a black market, it’s no surprise that its forerunners aren’t afraid to experiment with new approaches and technology.

The rapid adoption of IoT (Internet of Things) technology is one way in particular that this new generation of producers is stepping up, and they’re beginning to reap the rewards. But to better demonstrate how significant the implementation of IoT tech can be, we’ll peek over the fence at other craft-oriented food industries—namely wine and chocolate—to discover how effective they can be long-term for serious players in the cannabis industry.

The results, as you can probably guess, are astounding.

Farm Productivity and Precision is on the Rise

IoT tech isn’t just a cool new thing for experimental growers – it’s as necessary as air in the 21st century. New and veteran farms alike are discovering ways to streamline production and enhance the quality of their crops. One of the most common implementations of IoT tech in agriculture is the installation of smart measurement tools. Remote sensors can monitor soil acidity, humidity, salt concentrations, temperature and a variety of other metrics, automating the collection of data and providing a clear picture of plant health. For many farms, like E. & J. Gallo Winery, this is a game-changer.By installing hundreds of sensors per block and upgrading to a more precise irrigation system, Gallo was able to connect moisture measurements to a central system

Before placing sensors in over 250 acres of their vineyard, Gallo could only make irrigation adjustments at the large block level. Even with careful monitoring of moisture levels, the grape yield was inconsistent in size and flavor. By installing hundreds of sensors per block and upgrading to a more precise irrigation system, Gallo was able to connect moisture measurements to a central system. The system collects the data, considers the weather forecast, and automatically irrigates small areas of the vineyard as needed to ensure all plants are optimally watered. This resulted in a more uniform crop, less water waste and more desirable grapes.

Cannabis farms are starting to pick up on this simple approach as well. Organigram, one of Canada’s leading Cannabis producers, is well aware of the benefits of this kind of automation and data collection. “All our grow rooms are helping us learn all the time,” says Matt Rogers, head of production at Organigram. “With 20 grow rooms going, we can gather as much information about these plants as you would get in a century of summers.”

Automation and precision have enabled by Gallo and Organigram to improve yield and increase precision, which has helped them achieve their well-respected status in the wine and cannabis industries.

The Supply Chain is Becoming More Transparent

As much as we would like the industry to be free of scams and crooks, there’s more than a few producers stretching the truth when it comes to labeling product. MyDx, a cannabis chemical analyzer, recently revealed that the label on the package often does not totally coincide with the product within.Protecting your brand’s reputation is a necessity and IoT tech is helping some pioneering industries do that.

For example, the most frequently tested cannabis strain, “Blue Dream”, averages a 64% difference in chemical makeup from sample to sample. Similarly, “Gorilla Glue” and “Green Crack” show as much as 83% variation from sample to sample—largely because there’s no regulation of these names.

While variation is inevitable from grower to grower, plant to plant, and even between different parts of the same plant, misleading labels and the addition of ‘fillers’ is a growing issue for edible cannabis producers, and the threat it poses to your brand isn’t minor. Protecting your brand’s reputation is a necessity and IoT tech is helping some pioneering industries do that.

Wine in China is a powerful example of how improved traceability can reduce large-scale mislabeling. Brand-name winemakers in the country face a massive problem: 70% of imported wines are counterfeits. To combat this, winemakers are attaching near-field communication (NFC) labels to imported and domestic bottles. It’s a dramatic solution, but one that’s protecting the brand of winemakers dedicated to quality and transparency.

As the legalization of cannabis spreads and coveted strains emerge, so will the availability of counterfeits—or, at the very least, less-than-truthful labeling. This has proven to be true in almost every specialty market, and adopting improved traceability tech will defend your brand and reputation from the consequences of selling a product that’s discovered to be more ‘filler’ than cannabis.

Compliance is Easily Achieved

The conversation of cannabis regulation generally revolves around age restrictions and driving while impaired, but government compliance is far more complicated – especially for facilities that create cannabis-infused food products. And here’s the frustrating part for those who must (and should) maintain a food safety plan: every time a regulation is adjusted (or every time a new variation is added in another state), facilities must be able to document changes in procedures, recipes and hazard controls. It gets complicated quickly, especially if all the documentation is kept manually.

There’s a lot to be gained by connecting your systems and products to the Internet of ThingsA central, connected system is the best way for food manufacturers to streamline and automate a variety of documentation and food safety tasks, which can mean thousands of dollars saved over months or years. Using software like Icicle, facilities can create a comprehensive data environment that’s dynamic and accessible from anywhere. Incoming measurements from connected equipment and employee records are collected and an admin dashboard allows you to see what food safety systems are thriving and which need revisiting. The records – transformed into a compliant food safety plan – can then be pulled up during audits and inspections on the spot, saving the months that companies usually spend preparing documentation.

According to Mitchell Pugh of Chewter’s Chocolates, their system “gives me a great peace of mind in the sense to know we have all our information prepared and anything that an inspector is going to ask for – whether they’re looking for one product, a general system, a certain hazard, or a bill of ingredients or materials or an allergen – is easy for us to search for it, pull it up, and find exactly what they’re looking for.”

Considering that most food manufacturers still record measurements and create food safety plans manually, this is an area where progressive companies can quickly outpace their non-automated rivals.

Whether you’re a grower, dispensary, food producer, or some other kind of cannabis professional, there’s a lot to be gained by connecting your systems and products to the Internet of Things. Which direction will you take?

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.

How To Select The Best Monitoring System For Your Cannabis Greenhouses

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

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.
