Temperature and Relative Humidity in Greenhouses and Cannabis Production

There’s a saying: “An ounce of prevention is worth a pound of cure,” and this is no different with your sensors and controls of the greenhouse/indoor farming equipment that you use and rely upon everyday. Similar to any controlled environment, it is vital to monitor and proactively interpret the pressure, temperature, relative humidity, carbon dioxide (CO2) supplementation, and irrigation of your growing space. Losing control of your environment can lead to cultivation headaches ranging from poor air flow to extreme temperatures; additionally, high humidity and low irrigation rates can lead to the spread of disease and viruses.  Continue reading “Temperature and Relative Humidity in Greenhouses and Cannabis Production”

Keeping it Green: Monitoring CO2 Levels in Greenhouses

Plants thrive on CO2 for growth while producing oxygen.  One thing that many people do not know is that the optimal concentration for plant growth is over three times the atmospheric CO2 concentration today.1 This being the case, indoor gardens would be remiss if they didn’t attempt to elevate the CO2 levels in their environments to the ideal concentration. The most common way to increase the CO2 concentration is to use a propane burner to create CO2. The problem with having a propane burner in an enclosed space is that you need to know when to turn the burner on and off, as CO2 levels that rise above 1500 ppm are actually harmful to plants.
