Temperature Stress
Temperature stress in cannabis refers to the plant's physiological response to environmental conditions outside its optimal growing range, typically below 15°C or above 30°C. These conditions trigger visible morphological and biochemical changes—including altered pigmentation, modified trichome development, and shifts in secondary metabolite production. Temperature fluctuations during flowering are commonly associated with changes in terpene expression and cannabinoid ratios, making this trait of interest to breeders developing cultivars for specific climates. Lineage records frequently report that certain genetics show greater resilience or distinctive responses to temperature extremes. Understanding temperature stress responses helps breeders select for stability across variable growing conditions and regional adaptation.

Breeders monitor temperature stress responses to identify plants with consistent phenotypes across seasonal or regional growing conditions. Selecting for temperature-resilient genetics improves crop reliability in outdoor cultivation and helps stabilize secondary metabolite profiles across different cultivation environments.
