Thermal Compounds

Thermal compounds refer to volatile organic substances in cannabis that exhibit temperature-sensitive expression patterns during cultivation and storage. These include terpenes and minor cannabinoids whose concentration and profile can shift significantly based on growing conditions, curing temperatures, and preservation methods. Breeders and cultivators monitoring thermal compound behavior often track how phenotypes respond to heat stress, cold nights, and post-harvest processing temperatures. Understanding thermal compound stability is relevant for seed banking, clone preservation, and consistent cultivar reproduction across different growing environments. This family encompasses traits that make certain genetics more or less stable under temperature fluctuation.

Breeders working with thermally sensitive genetics carefully document environmental parameters to maintain phenotypic consistency across generations. Selecting for thermal stability—or conversely, for desirable thermal expression—is a deliberate breeding strategy in cultivar development and preservation.
