Environmental Humidity
Environmental humidity refers to the moisture content in the air surrounding cannabis plants during cultivation. Humidity levels significantly influence plant physiology, including transpiration rates, nutrient uptake, and susceptibility to fungal pathogens. Cannabis cultivators typically manage humidity across growth stages, with seedling and vegetative phases often requiring 60-70% relative humidity, while flowering stages are frequently maintained at lower levels (40-50%) to reduce disease pressure. Humidity interacts with temperature to create vapor pressure deficit (VPD), a key metric breeders and growers use to optimize growing conditions. Understanding humidity's role in plant development helps inform strain selection and cultivation protocols, particularly for varieties bred in specific climate zones.

Breeders working with humidity-sensitive genetics may select for mold-resistant phenotypes or cultivars adapted to high-humidity environments. Strain lineages often carry inherited traits related to leaf structure and resin production that influence how plants respond to variable moisture conditions.
