Temperature Flowering

Temperature Flowering refers to the aromatic profile that emerges when cannabis plants experience specific temperature fluctuations during their flowering phase. Cooler nights (typically 10–15°C) during late bloom commonly trigger heightened terpene expression and pigment development in some cultivars, often resulting in more pronounced floral, fruity, or spice-forward aromatics. This phenomenon is frequently documented in breeding records, particularly among photoperiod-dependent strains grown in controlled environments. Breeders working with heritage or outdoor-adapted genetics often observe that temperature-driven aroma shifts correlate with natural seasonal cues, making this trait relevant to strain stabilization and phenotype consistency. The aromatic changes are attributed to terpene synthesis responses rather than new compound creation, meaning existing volatile profiles become mo

Breeders select for temperature-responsive genetics when developing strains intended for outdoor cultivation or environments with natural seasonal temperature swings. Understanding and documenting these aroma shifts helps stabilize desired flavor profiles across multiple generations and growing conditions.
