Regulatory Compliance As the industry shifts from small, unregulated cultivation rooms to larger commercial-scale operations subject to oversight, cannabis production is becoming more sophisticated. Part of this transition involves protecting crops from damaging airborne microorganisms that might proliferate in room air and cause the plants to develop mold and powdery mildew. Not only can such microbes ruin the crop, but they can force the entire facility to shut down due to health violations. There are a variety of naturally occurring airborne microorganisms that can cause plants to develop mold or a powdery mildew, rendering them worthless. Standard HVAC systems increase this threat as these damp and dark systems offer a perfect breeding ground for microbial growth. Worse still, ventilation systems are very efficient at spreading microscopic spores throughout a building.
