Environmental Factors Terpene Production

Environmental factors significantly influence terpene expression in cannabis plants, with light spectrum, temperature, humidity, and soil conditions shaping volatile compound profiles. Research in controlled cultivation environments demonstrates that terpene concentrations and ratios shift based on photoperiod length, day/night temperature differentials, and relative humidity levels throughout growth stages. Breeders and cultivators working to stabilize terpene phenotypes must account for these variables, as identical genetics can produce notably different aromatic signatures under varying conditions. This category encompasses the interplay between genetics and cultivation environment—a critical consideration for reproducible terpene expression in breeding programs and commercial production.

Breeders studying terpene inheritance must control environmental variables to distinguish genetic terpene potential from environmentally-induced variation. Understanding these factors helps establish baseline profiles and identify which traits are stably expressed versus environmentally sensitive.
