Temperature Differential

Temperature differential in cannabis breeding refers to the variation in terpene expression and plant phenotype across different growing temperatures. Plants exposed to cooler night temperatures often develop distinct terpene profiles compared to those in consistent warm conditions, with some research suggesting temperature swings can influence volatile compound concentration and aromatic complexity. This environmental factor is frequently noted in breeding logs and cultivation studies, though terpene expression remains polygenic and influenced by multiple variables beyond temperature alone. Breeders and researchers track temperature differential effects to understand how environmental conditions shape the chemical fingerprint of a given cultivar during development.

Breeders working in controlled environments document temperature variance as a potential tool for phenotype stabilization and terpene profiling. Understanding how day/night temperature fluctuations interact with genetic background helps inform seed selection and cultivation protocols in breeding programs.
