Light Exposure
Light exposure refers to the intensity, spectrum, and photoperiod (day/night cycle length) that cannabis plants receive during cultivation. Breeders and growers manipulate light conditions to influence flowering initiation, cannabinoid expression, and terpene production across different growth stages. Photoperiodic cultivars—those dependent on shortening daylight to flower—remain the dominant type in breeding programs, though photoperiod-independent (autoflowering) genetics have expanded breeding possibilities since the early 2000s. Understanding how specific strain genetics respond to light wavelengths and duration helps breeders select for consistent flowering times and desired phenotypic traits. Light spectrum (UV, blue, red, far-red) can shift secondary metabolite profiles and plant architecture without changing underlying genetics.

Breeders evaluate light-response phenotypes to develop cultivars suited to different growing environments—indoor LED systems, outdoor seasonal conditions, and controlled-environment agriculture. Consistent light-response traits are critical for stabilizing F1 hybrids and maintaining predictable flowering windows across seed batches.
