Uv Exposure Genetics

UV exposure genetics refers to how cannabis plants respond genetically to ultraviolet radiation, particularly UVB light, which can trigger increased production of certain secondary metabolites including cannabinoids and flavonoids. This trait is not a terpene itself, but rather a genetic expression pattern—some lineages are documented to show stronger UV-responsive phenotypes than others. Breeders working with UV-sensitive genetics often observe variable resin production and pigmentation changes under controlled UVB conditions. Understanding UV response genetics is relevant for both indoor breeding programs (where UVB supplementation is controlled) and outdoor cultivation environments. This remains an active area of cannabis breeding research, with growers exploring whether enhanced UV genetics justify the energy investment in supplemental lighting.

Breeders selectively work with UV-responsive lineages to explore potential shifts in secondary metabolite production under controlled light environments. Establishing stable UV-response traits through selection requires multi-generational testing and environmental standardization.
