Uv B Radiation

UV-B radiation exposure during cannabis cultivation has become a subject of interest in breeding programs and cultivation research. Breeders observe that controlled UV-B exposure can influence secondary metabolite production, including cannabinoid and terpene profiles, though mechanisms remain under investigation. Some cultivation protocols incorporate measured UV-B wavelengths (280–315 nm) as an environmental variable, with growers noting potential shifts in plant morphology and chemical composition. This represents an environmental manipulation strategy rather than a genetic trait, distinguishing it from inheritable characteristics. Research into UV-B effects remains ongoing, with results varying significantly based on intensity, duration, and plant genetics.

Breeders studying environmental stress responses document how UV-B exposure correlates with changes in secondary metabolite expression across different genetic backgrounds. Understanding these responses helps inform cultivation protocols and may inform selection for stress-resilient or metabolite-rich phenotypes.
