Cold Weather Pheno
Cold Weather Phenotype (or 'cold pheno') describes cannabis plants exhibiting heritable traits that support survival and completion in low-temperature environments. These expressions often include shortened flowering windows, robust resin production, and structural adaptations like compact internodes and reinforced cell walls. Lineage records frequently report cold-weather phenotypes emerging from landrace populations cultivated at high altitudes or northern latitudes—notably Hindu Kush, Afghan, and Tibetan heritage lines. The trait reflects both genetic selection pressure and phenotypic plasticity in response to chilling stress. Modern breeders working in northern cultivation zones intentionally identify and preserve these phenotypes to reduce crop failure risk and extend growing seasons.

Breeders leverage cold-weather phenotypes as parent stock to develop regionally adapted cultivars with lower failure rates in marginal climates. Selecting for these traits across generations helps stabilize cold tolerance while maintaining desired cannabinoid and terpene profiles.
