Low Temperature Separation
Low Temperature Separation refers to a breeding selection approach where cultivators expose plants to cool night temperatures—typically 10–15°C (50–59°F)—to trigger anthocyanin and other pigment expression. This technique is commonly associated with producing purple, blue, and red colorations in foliage and flowers, independent of underlying genetics. The practice gained attention in cannabis breeding during the early 2000s as growers documented repeatable color shifts under controlled temperature regimes. Breeders working in this category often combine low-temperature exposure with genetic predisposition for pigmentation to achieve stable visual traits across generations. Success depends on timing, duration, and plant stage; late-flower and early-cure phases show the most pronounced color response.

Breeders use low-temperature separation as a phenotype refinement tool rather than a genetic modifier—it reveals latent pigmentation potential without altering the plant's DNA. Understanding this environmental trigger helps establish stable, visually distinctive cultivars for commercial and specialty markets.
