Cold Weather Phenotype
Cold Weather Phenotype refers to observable characteristics that emerge when cannabis plants are cultivated or mature in cooler temperatures, typically below 65°F (18°C). Environmental stress from cold exposure often triggers increased anthocyanin and carotenoid production, resulting in purple, blue, or deep red coloration in leaves and flowers. These phenotypes are not genetic mutations but rather environmentally-induced expressions of existing genetics. Lineage records frequently report that certain strain families—particularly those with Afghani or high-altitude heritage—exhibit more pronounced cold-weather color shifts and terpene profile changes. Breeders working in northern climates or seasonal cultivation often document these traits as consistent markers of temperature sensitivity within breeding lines.

Breeders track cold-weather phenotypes to identify genetics suited for outdoor cultivation in cooler regions and to understand environmental gene expression patterns. Understanding temperature-triggered traits helps inform strain selection for specific growing environments and climate zones.
