Temperature Terpene Expression

Temperature terpene expression refers to how volatile aromatic compounds in cannabis shift their profiles based on environmental conditions during cultivation and post-harvest handling. Cooler temperatures often preserve lighter, more delicate terpenes like limonene and pinene, while warmer conditions may favor heavier compounds like myrcene and caryophyllene. This phenomenon occurs because terpenes have distinct boiling points—some volatilize readily at elevated heat, while others remain stable. Breeders and cultivators working with temperature-sensitive genetics must carefully manage growth environments and drying/curing protocols to maintain desired aromatic profiles. Understanding this family helps explain why the same genetic line can produce noticeably different terpene expressions across different grow facilities or seasons.

Breeders selecting for stable terpene profiles often prioritize genetics that maintain consistent aromatic output across temperature fluctuations. Cultivators use knowledge of temperature terpene expression to dial in specific aromatic outcomes, making this a key consideration in phenotype hunting and consistency protocols.
