High Temperature Phenotype
The High Temperature Phenotype describes cannabis plants exhibiting structural and biochemical adaptations to sustained heat stress during growth. Breeders working in hot climates or intentionally selecting for heat tolerance have documented traits including altered leaf morphology, modified terpene profiles, and shifts in cannabinoid ratios under elevated temperatures. Lineage records frequently report that certain genetic backgrounds—particularly those derived from equatorial or desert-adapted landraces—maintain more stable phenotypes when exposed to 85–95°F+ conditions. This family is distinct from heat damage responses; rather, it reflects genetically encoded tolerance mechanisms. Understanding these phenotypes is valuable for cultivation in challenging environments and for breeding programs targeting climate-resilient varieties.

Breeders use High Temperature Phenotype selection to develop cultivars suited to outdoor production in arid or subtropical regions, and to create genetics that resist stress-induced degradation of desirable traits. Markers associated with this family help identify parent plants capable of passing heat tolerance to offspring while maintaining cannabinoid and terpene stability.
