Light Degradation Factors

Light degradation factors refer to how cannabis flower quality and volatile compounds diminish when exposed to UV radiation and visible light wavelengths during storage and cultivation. Chlorophyll breakdown, terpene oxidation, and cannabinoid photoisomerization occur at measurable rates depending on light intensity, duration, and spectrum. Breeders and cultivators working with preservation genetics document how certain phenotypes maintain aromatic and chemical stability under light stress better than others. Understanding these factors informs seed bank storage protocols, harvest-to-cure timelines, and controlled environment design. Lineage records frequently note cultivars bred for low-light tolerance or resilience to light-induced degradation in extended vegetative cycles.

Breeders select for cultivars showing slower terpene loss and cannabinoid stability under standardized light exposure. This trait is particularly relevant for seed production lines, mother plant libraries, and indoor cultivation genetics requiring extended photoperiods or supplemental lighting.
