Growing Condition Influence

Growing conditions profoundly shape terpene expression in cannabis, with environmental factors like temperature, light spectrum, humidity, and soil composition directly influencing which volatile compounds develop during flowering. Breeders and cultivators recognize that a single genotype can produce markedly different terpene profiles depending on cultivation variables—a phenomenon often termed 'phenotypic plasticity' in terpene production. Temperature fluctuations, particularly cooler nights during late flower, are frequently associated with increased terpene concentration in some lineages. Light intensity and spectrum affect secondary metabolite synthesis, while nutrient availability and microbial soil communities can modulate volatile compound expression. Understanding these interactions is essential for breeding programs aiming to stabilize desirable terpene profiles across diverse

Breeders working to develop consistent terpene-dominant cultivars must evaluate candidate lines across multiple growing conditions to identify genotypes with stable terpene expression. Cultivars selected for terpene stability in controlled environments may exhibit significant variation when grown outdoors or in suboptimal conditions, influencing selection strategies.
