Humidity Temperature Effects

Humidity and temperature conditions during cultivation significantly influence volatile organic compound (VOC) expression in cannabis plants. Higher temperatures typically promote terpene volatilization, while humidity levels affect both terpene production rates and preservation during drying and curing phases. Breeders and cultivators track these environmental parameters because phenotypic aroma expression can vary substantially across identical genetic lines grown under different conditions. Low-humidity, cooler environments often retain more delicate aromatic compounds, whereas high heat and moisture may shift terpene profiles toward different volatilization patterns. Understanding these relationships helps distinguish genetic aroma potential from environmentally-induced variation.

Breeders studying aroma stability evaluate how their lines perform across humidity and temperature ranges to identify genotypes that maintain consistent terpene profiles. Seed companies often document environmental sensitivity as a cultivation note, helping growers optimize conditions for target aroma expression.
