Temperature Humidity Interaction

Temperature and humidity interactions significantly influence terpene expression and stability in cannabis plants throughout cultivation and post-harvest stages. Environmental conditions—particularly heat, light exposure, and moisture levels—can trigger or suppress terpene synthesis in the trichomes, and subsequently affect terpene volatility and degradation rates. Breeders and cultivators monitoring these variables often observe shifts in aromatic profiles under different environmental regimes, even within genetically identical plants. This relationship is particularly relevant during flowering, when many secondary metabolites accumulate, and during storage, when terpenes can oxidize or evaporate. Understanding these interactions remains foundational for consistent phenotype expression and preservation of intended chemical profiles across cultivation cycles.

Breeders selecting for stable terpene expression often evaluate candidate lines across varied environmental conditions to identify genotypes that maintain consistent aromatic profiles. Cultivators working with breeder recommendations typically fine-tune temperature and humidity ranges to maximize expression of target terpenes associated with particular strain families.
