Plants contaminated by pests and disease can result in drastically reduced yields, lower cannabinoid and terpene levels, or, in worst case scenarios, completely collapse, leading to total crop failure.

In addition to trying to limit external contaminants, unbalanced humidity is considered a main contributor to pest and disease issues. Cannabis crops suffer when humidity levels aren’t just right. Many growers know that low humidity and dry conditions can create an appealing environment for spider mites, and high humidity can create an environment ripe for botrytis (bud rot), among other diseases.

Finally, a constant swing in humidity can create an unhealthy environment for the plant, which invites certain diseases such as powdery mildew to infiltrate the crop.
