Managing VPD for Cannabis
The vapor pressure deficit (VPD) is the difference between the moisture currently in the air and the maximum moisture it can hold when saturated. As we discussed in our previous blog post, VPD is an important parameter to measure and control because it directly influences plant transpiration. In this blog post, we’ll explain how to determine the VPD of the grow room using temperature and humidity, the ideal VPD levels for cannabis and the equipment needed to monitor and adjust VPD.

Cannabis Pests and Pathogens
Pests and pathogens threaten cannabis crops. Pests—larger organisms[1] like insects and mites—physically damage plants, whereas pathogens are microorganisms that infect and cause diseases within plants. A useful rule of thumb might be that while pests can typically be removed physically, pathogens cannot.Both pests and pathogens pose distinct threats to plant health, reducing cannabis yield and quality. This blog post explores some of the most common pests and pathogens that cannabis growers may encounter, the specific plant sites they target, and …
