Temperature Stress Phenotypes
Temperature stress phenotypes refer to observable plant characteristics that emerge when cannabis is exposed to environmental temperature fluctuations outside optimal growing ranges. These phenotypes—including altered leaf pigmentation, modified leaf size, changed internodal spacing, and shifts in trichome density—are triggered by cold, heat, or diurnal temperature swings during vegetative or flowering stages. Breeders and cultivators document these responses because they reveal both genetic predisposition and phenotypic plasticity; some strains show purple or red anthocyanin development under cold stress, while others demonstrate compact growth or accelerated flowering under heat pressure. Understanding temperature stress phenotypes is important for lineage selection, as certain genetics reliably express desirable structural or visual traits under specific thermal conditions.

Breeders select for temperature resilience by identifying plants that maintain desired morphology and flowering speed across cold-night or heat-day scenarios. Documenting stress phenotypes helps establish which genetic backgrounds pass stable traits to offspring versus which produce inconsistent F1 or F2 expression.
