Cannabinoid Thermal Sensitivity

Cannabinoid thermal sensitivity refers to the temperature-dependent stability and expression of cannabinoids during cultivation, processing, and storage. Unlike volatile terpenes that readily evaporate, cannabinoids like THC and CBD exhibit variable degradation rates depending on heat exposure, light, and environmental conditions. Breeders and cultivators monitor thermal stability because cannabinoid profiles can shift or degrade if plants are exposed to excessive heat during flowering or drying. Understanding this trait helps explain why identical genetics may produce different cannabinoid ratios across growing environments. This characteristic is particularly relevant for seed preservation and post-harvest handling protocols.

Breeders select for genetic lines that maintain stable cannabinoid expression across temperature ranges, especially when developing cultivars for diverse climates or long-term seed storage. Thermal stability data informs decisions about drying temperatures, cure conditions, and packaging requirements to preserve target cannabinoid profiles.
