Light Spectrum Expression
Light Spectrum Expression refers to how cannabis plants develop pigmentation, structure, and biochemical profiles in response to different wavelengths of light during cultivation. The spectral composition—particularly ratios of blue, red, and far-red light—influences chlorophyll synthesis, cannabinoid and terpene production pathways, and internode spacing. Breeders and cultivators document these responses as a heritable trait influenced by both genetics and environmental conditions. Understanding spectrum expression helps distinguish between phenotypic plasticity and stable genetic traits when evaluating breeding stock across different growing systems.

Breeders select for consistent light-response traits when developing cultivars optimized for specific growing environments (indoor LED, HPS, greenhouse, outdoor). Documenting spectrum expression during breeding trials helps identify genotypes with stable secondary metabolite profiles across lighting conditions, reducing variability in cannabinoid and terpene composition.
