Far Red Light

Far red light (700–800 nm wavelength) is a spectral component used in cannabis cultivation research, distinct from visible red light and infrared radiation. In breeding contexts, far red exposure during photoperiod manipulation may influence flowering timing and plant morphology, though mechanisms remain an active area of horticultural study. Breeders working in controlled-environment genetics sometimes reference far red light protocols when documenting phenotypic expression under specific spectrum conditions. This trait classification is relevant to seed production and strain stability research rather than a sensory aroma category.

Far red light is primarily a cultivation variable tracked by breeders optimizing flowering photoperiods and plant structure in seed production environments. Documentation of far red light exposure conditions helps establish reproducible phenotype baselines across generations.
