Environmental Factors Temperature

Temperature during cultivation significantly influences cannabis plant development, metabolite production, and phenotypic expression. Breeders and cultivators recognize that daytime/nighttime temperature differentials, seasonal shifts, and absolute temperature ranges shape cannabinoid and terpene profiles, plant structure, and flowering timing. Environmental temperature stress—both heat and cold exposure—can trigger distinct secondary metabolite responses that vary by genotype. Temperature management is considered a core environmental variable in controlled breeding programs, as it interacts with light cycle, humidity, and nutrient availability to determine final plant characteristics. Lineage records frequently document how specific strain families express different phenotypes under varied temperature regimens. Understanding these responses helps breeders stabilize desired traits and op

Breeders select for temperature resilience and phenotypic consistency by exposing seed populations to controlled temperature ranges and identifying stable offspring. Temperature-responsive traits—such as anthocyanin expression, terpene volatility ratios, or internodal spacing—are heritable markers used to refine strain stability across growing environments.
