Terpene Development Light Exposure

Light exposure during cultivation significantly influences terpene synthesis and volatility in cannabis plants. The intensity, spectrum, and photoperiod interact with plant metabolism to modify secondary compound profiles. UV-B and full-spectrum lighting are commonly associated with increased terpene production in certain cultivars, though response varies by genotype. Light stress—both deficiency and excess—can trigger protective metabolite shifts. Understanding these photobiological mechanisms helps breeders and cultivators predict terpene outcomes across different growing environments.

Breeders working with terpene-forward selection programs often evaluate parent lines under controlled light conditions to standardize phytochemical phenotyping. Light-environment stability is critical when establishing consistent terpene profiles across seed generations and cultivation sites.
