Uv B Radiation

UV-B radiation is not a terpene but rather an environmental factor that influences terpene and cannabinoid synthesis in cannabis plants. Light wavelengths between 280–320 nanometers trigger specific biochemical pathways in plant tissue, particularly affecting the production of secondary metabolites. Research in cannabis cultivation suggests that controlled UV-B exposure during flowering may influence terpene expression and resin density, though mechanisms remain incompletely understood. Breeders and cultivators studying this variable often document changes in aromatic profiles across the same genetic line under different light conditions. UV-B interaction with genetics highlights why identical strains can express different terpene ratios depending on cultivation environment.

Plant geneticists and breeding programs increasingly investigate UV-B as a non-genetic variable that modifies phenotypic expression. Understanding how specific lineages respond to light stress helps breeders select for resilience traits and optimize terpene development in controlled environments.
