5 Tech Systems Anyone With a Cannabis Greenhouse Should Be Using

     

Cannabis Greenhouse Tools

Greenhouse cultivation of cannabis is “a dramatically different growing paradigm,” experts say. In a traditional outdoor grow, the farmer has little control over key environmental factors. In a greenhouse, environmental conditions can be more finely managed, which gives the grower an edge. But this self-contained environment also requires more attention in order to ensure that all the main elements are in proper balance.

Technology offers a range of opportunities for the commercial grower to make effective use of the greenhouse environment. The latest tools enable the grower to exert a high degree of control without having to be constantly on-site. They make the growing process more efficient and can drive higher yields as well.

To that end, let’s consider the five technologies that should be present in every marijuana greenhouse: a well-designed lighting system, intelligent ventilation design, environmental sensors, an automated control system, and a remote management app.

1. Lighting

Given the high energy use inherent in indoor cannabis production, a well-designed system for lighting and heating is critical. You need the right suite of high-efficiency lighting fixtures, along with the controls that allow for remote adjustment. Ideally, such a system will result in higher efficiency and lower operating costs, and it should utilize the sun as a primary light source.

You’ll especially want to track Daily Light Integral, is the number of light particles that are received in one full day. DLI influences plant growth and can affect a plant's root system, stems, and flowering stage. The ability to track and control DLI is key to a successful grow.

Supplemental lighting helps ensure adequate and appropriate lighting at all growing stages. In an automated greenhouse, supplemental lighting ensures plants get the needed amount of illumination regardless of latitude or other environmental factors.

2. Ventilation

Intelligent ventilation design is likewise a key ingredient. Such a system may incorporate both natural ventilation via roof vents, sidewall vents, and rollup sides, as well as forced air ventilation, driven by mechanical systems such as exhaust fans. You need ventilation to remove hot air from inside the greenhouse, as well as to promote air movement, which is necessary for plant health. Plants are happiest when there’s enough air flow to rustle their leaves a bit.

3. Sensors

Sensors are necessary equipment in any modern greenhouse setting, with thermometers, humidity gauges, and pH sensors among the most vitally important.

  • The pH scale runs from 1 to 11, with lower numbers indicating acidic and higher numbers being alkaline. The preferred pH levels for cannabis are between 5.5 to 6.5. A digital will deliver both continuous and intermittent measurements of pH level, storing historical data and automatically communicating readings on to the environmental controller.

  • Cannabis grows best at temperatures between 70 and 85 degrees F during the day, and slightly cooler temperatures at night. Digital thermometers can be preset with high and low parameters to alert growers when temperatures fluctuate beyond an acceptable range.

  • Optimal humidity levels will vary according to the plant’s developmental stage and must be monitored and adjusted along with other key, interdependent variables such as temperature and air flow. Often combined with a temperature sensor, greenhouse humidity sensors track moisture levels with a high degree of accuracy, with smart features designed to trigger action when levels deviate beyond established parameters.

4. Control Systems

Automated control systems leverage technology to maintain optimum growing conditions in the greenhouse while significantly easing the labor burden. Such systems can be set to deliver moisture and nutrients at fixed levels at set times. By setting parameters, growers can establish an automated regimen of care, with the control system automatically adjusting variables such as heat, humidity, and lighting. Such systems may also track conditions over time, giving the grower the opportunity to reflect back on which strategies are more or less effective and to make adjustments accordingly in support of future crops.

5. Mobile Connection

Mobile connectivity enables the grower to interact with the control system when off-site, via a smartphone app. Such systems not only make critical sensor data available 24/7; they also empower the grower to make adjustments on the fly, adding to or subtracting from the greenhouse environment as local conditions vary. This allows the grower to balance heat and humidity, adjust lighting based on external conditions, and track nutrient dosing.

These technological enhancements around automation and remote management become especially important as a cannabis grower seeks to expand an operation.

With a bigger grow, it gets harder to stay on top of environmental conditions. Short of being physically present all the time—which most growers find a prohibitive proposition—technology offers the surest means for tracking and responding to the needs of the greenhouse grow.
