Temperature Stress Coloration
Temperature stress coloration refers to the expression of anthocyanins and other pigments in cannabis plants when exposed to cooler nighttime temperatures, typically below 50°F (10°C). This trait manifests as purple, red, blue, or dark burgundy hues in leaves, stems, and flowers—distinct from genetic predisposition for color. The coloration appears most prominently during flowering and late vegetative stages when plants experience repeated thermal stress. Breeders and cultivators commonly observe this phenomenon across diverse genetic backgrounds, making it a useful indicator of environmental conditions rather than a fixed genetic marker. Temperature stress coloration has become an area of interest in breeding programs seeking to understand phenotypic plasticity and environmental response mechanisms.

Breeders working with temperature stress coloration study how genetic backgrounds respond to thermal triggers, helping optimize cultivation protocols and develop stable lines with consistent cold-season performance. Understanding this trait aids in selecting for resilience in cooler climates while distinguishing environmental responses from true genetic color traits.
