Uv B Sensitivity

UV-B sensitivity in cannabis refers to how plant tissues and secondary metabolites respond to ultraviolet-B radiation exposure during cultivation. While cannabis naturally encounters UV-B in outdoor environments, indoor growers sometimes employ supplemental UV-B lighting to study or modulate cannabinoid and terpene production. This is primarily a physiological trait rather than a traditional aroma descriptor, though some breeders observe correlations between UV-B stress responses and terpene expression patterns. Lineage records and cultivation research frequently document strain-specific variations in how plants tolerate or benefit from UV-B exposure. Understanding UV-B sensitivity is relevant to controlled-environment agriculture and phenotype stabilization rather than sensory profiling.

Breeders working in controlled-environment genetics track UV-B sensitivity as a cultivation variable affecting cannabinoid ratios and secondary metabolite profiles. Selecting for or against UV-B tolerance helps stabilize phenotypes across different growing environments and light conditions.
