Environmental Trait Temperature Range

Temperature range classification refers to the environmental conditions under which a cannabis cultivar demonstrates optimal growth and cannabinoid/terpene production. Breeders document the minimum and maximum temperatures at which a strain maintains vigor, and the preferred range for phenotypic stability. This trait varies significantly across lineages—some cultivars show resilience in cooler climates (50–70°F), while others thrive in warmer conditions (70–85°F). Temperature range data is particularly relevant for regional breeding programs, greenhouse optimization, and understanding how genetics from different geographic origins perform under specific conditions. Documentation of temperature tolerance helps growers and breeders predict how a given genotype will express phenotypically across seasons or climates.

Breeders use temperature range data to select parent plants suited to target growing environments and to stabilize offspring for consistent performance across climate zones. Crossing cultivars with different temperature preferences can produce hybrid lines with broader environmental tolerance, a key goal in developing regionally adapted seed stock.
