Temperature Humidity

Temperature and humidity are environmental factors that significantly influence cannabis volatile compound expression rather than being aromas themselves. During cultivation, fluctuating temperature and humidity levels can trigger or suppress the production and volatility of terpenes and other aromatic compounds. Breeders and growers recognize that identical genetics may express different aromatic profiles depending on environmental conditions—cooler nights often preserve delicate volatile compounds, while excessive humidity can promote mold and reduce terpene retention. Understanding how these environmental variables interact with plant physiology helps breeders select for strains with stable aromatic expression across varying grow conditions. Documentation of environmental impact on aroma is increasingly important in breeding programs focused on consistency and resilience.

Breeders select for genotypes that maintain aromatic stability across temperature and humidity ranges, reducing environmental sensitivity. This trait selection supports cultivators working in diverse climates and helps stabilize volatile compound profiles for seed line consistency.
