Post Harvest Volatility

Post-harvest volatility refers to the dynamic chemical changes that occur in cannabis plant material after harvest, particularly in terpene profiles and cannabinoid expression. Environmental factors—including temperature, humidity, light exposure, and storage duration—directly influence which volatile compounds remain stable versus those that degrade, oxidize, or transform into secondary metabolites. This phenomenon is well-documented in cannabis research and presents both challenges and opportunities for cultivators and breeders seeking consistent end-product profiles. Understanding post-harvest volatility is critical for seed preservation, breeding stock maintenance, and consistent genetic expression across production cycles.

Breeders and seed bankers monitor post-harvest volatility when selecting parent plants and establishing preservation protocols. Strains exhibiting stable terpene profiles under standard storage conditions are often prioritized in breeding programs, as they demonstrate predictable phenotypic expression across multiple generations and growing environments.
