With almost 30 states now allowing some sort of legal use of marijuana, it is not surprising that the number of cannabis growing facilities in the U.S. is exploding. These growing facilities range from small farms that supply medical marijuana to local patients to large, multimillion-dollar facilities that produce enough to supply entire states with both recreational and medical marijuana.
State and local ordinances concerning cannabis growing facilities can differ from one location to the next, but the actual cultivation of cannabis does not vary too much. Like most plants, cannabis needs just the right amount of light, humidity, heating/cooling, nutrients, and ventilation in order to grow and thrive. Ventilation is probably the least understood part of this equation, but if the system is not designed properly, then the plants — and the workers — can suffer.
