Cold Temperature Phenotype
Cold temperature phenotypes refer to cannabis plant expressions that develop distinctive visual and chemical characteristics when cultivated in cooler growing conditions, typically below 65–70°F (18–21°C). These phenotypes often display enhanced anthocyanin production, resulting in purple, blue, or dark red coloration in leaves and flowers. Breeders working in this category have selected for genetic stability of cold-responsive traits across generations. Temperature-dependent expression means the same genotype may appear markedly different under warm versus cool conditions, making environmental documentation critical for breeding records. Cold phenotypes are particularly common in indica-dominant lineages and high-altitude origin genetics. Understanding these expressions helps breeders predict trait stability and plan cultivation protocols for consistent seed production.

Breeders leverage cold phenotypes to develop visually distinctive cultivars and to study environmental gene expression without chemical modification. Selecting parents that reliably express cold-responsive traits allows creation of photoperiod and temperature-stable lines suitable for varied climates.
