Cool Temperature Response
Cool Temperature Response refers to genetic traits that influence how cannabis plants develop color, terpene expression, and morphology when exposed to cooler growing conditions. Plants carrying these genetics commonly shift toward purple, blue, or red pigmentation during flowering in temperatures below 50–65°F, driven by anthocyanin and other secondary metabolite production. Lineage records frequently report cool-temperature phenotypes emerging from high-altitude and cold-climate breeding populations, particularly those with Afghani, Tibetan Kush, or Northern European heritage. The trait involves multiple genes regulating pigment synthesis and is often heritable across generations, though expression depends heavily on environmental timing and intensity. Breeders working with these genetics value them for phenotypic diversity and for developing cultivars suited to outdoor or greenhouse p

Breeders select for stable cool-temperature response to create consistent visual and aromatic phenotypes in variable climates, and to develop cultivars that thrive in shorter growing seasons or high-altitude environments. Understanding the genetic basis helps predictably stack this trait with desired yield, potency, or terpene profiles.
