Light Spectrum
Light spectrum refers to the wavelengths of light that influence cannabis plant development, physiology, and secondary metabolite production. Different wavelengths—particularly blue (400–500 nm), red (600–700 nm), and far-red light—trigger distinct morphological and biochemical responses in cannabis. Breeders and cultivators working in controlled environments often manipulate spectrum to influence vegetative structure, flowering timing, and terpene/cannabinoid profiles. Lineage research increasingly documents how spectrum conditions during breeding selections can affect offspring trait expression. Understanding light spectrum is foundational to modern indoor breeding programs and phenotype stabilization work.

Breeders use controlled light spectra to select for specific plant structures (compact vs. tall), flowering responses, and secondary metabolite accumulation. Spectrum consistency during breeding populations helps ensure stable trait expression across generations and reduces environmental phenotypic drift.
