Cultivation Environmental Factors

Cultivation environmental factors—including light spectrum, temperature, humidity, and soil composition—significantly influence terpene expression in cannabis plants. These conditions affect enzyme activity and metabolic pathways that produce volatile compounds, meaning identical genetics can yield different aromatic profiles under varying growing conditions. Light wavelengths, particularly in the UV and blue spectrum, are commonly associated with increased terpene accumulation in flowers. Temperature fluctuations between day and night cycles, along with relative humidity levels, often impact both terpene quantity and the ratio of specific compounds. Breeders and cultivators document these relationships to understand how environmental manipulation shapes secondary metabolite development. This knowledge helps distinguish between genetic terpene potential and environmentally-driven express

Breeders studying terpene inheritance must control growing environments to accurately identify which aromatic traits are genetically fixed versus environmentally plastic. Understanding environmental factors allows breeders to evaluate true phenotypic expression and select parents that reliably produce target terpene profiles across diverse cultivation settings.
