Molds and Marijuana Grow Houses

Marijuana grow houses are houses where cannabis is grown, legally or otherwise, under controlled conditions. The grower ensures the right temperature, humidity, moisture, and other growth factors for the plants. They also make sure they avoid the introduction of pathogens and pests from the external environment. However, cannabis plants are always under the threat of fungal outbreaks.

Due to the high temperature and humidity requirements for cannabis growth, molds often grow alongside them. Also, the restrictive light requirement, especially during the flowering stage, encourages mold growth and reproduction. Therefore, mold spores are to be expected in any cannabis grow house.
