Temperature Range

Temperature range refers to the spectrum of ambient conditions under which cannabis cultivars thrive or tolerate environmental stress. Plant genetics carry inherent temperature sensitivity—some lineages derive from tropical or equatorial origins and prefer warmth, while others trace to temperate or mountainous regions and tolerate cooler conditions. Breeders document temperature responses because they directly affect phenotypic expression, flowering timing, terpene development, and cultivation success across different climates and seasons. Understanding a strain's temperature preferences is essential for matching genetics to indoor climate control or outdoor seasonal windows. This trait category helps growers optimize yield and quality by aligning cultivation methods with genetic predisposition.

Cannabis breeders actively select for temperature tolerance or preference to create cultivars suited to specific regions—cool-weather adapted lines for northern climates, heat-tolerant genetics for tropical zones. Temperature stability during critical growth phases (seedling, flowering) influences cannabinoid and terpene profiles, making this trait valuable for targeted cross-breeding programs.
