Late Flower Degradation

Late flower degradation refers to the breakdown of volatile terpenes during the final weeks of bloom, particularly as flower tissue matures and environmental stress increases. Cannabinoid-rich cultivars often show measurable terpene loss in the final 7-14 days before harvest, with certain monoterpenes (limonene, pinene) typically declining faster than heavier sesquiterpenes. This phenomenon is influenced by temperature fluctuations, light intensity, humidity shifts, and plant senescence. Breeders and cultivators document terpene profiles at multiple harvest windows to understand when peak aromatic expression occurs versus when degradation becomes significant. Understanding late-flower terpene dynamics is essential for timing harvest decisions and predicting final product profiles.

Breeders working to stabilize terpene retention often select parents showing slower degradation curves or selecting for cultivars expressing more stable, heavier sesquiterpenes. Documentation of terpene stability across the final flowering period helps distinguish phenotypes suited to extended flowering or early-harvest strategies.
