Temperature Range

Temperature range classification describes the ambient climate conditions under which a cannabis cultivar demonstrates optimal growth, development, and cannabinoid expression. Breeders and cultivators reference temperature ranges to match plant genetics with specific growing environments—whether indoor controlled systems, greenhouse conditions, or outdoor regional climates. Historical lineage records frequently report the geographic origins of parent plants, which correlate directly with their temperature tolerance windows. Modern breeding programs often select or stabilize strains for specific thermal requirements, as photoperiod-sensitive and auto-flowering varieties may respond differently to temperature fluctuations. Understanding a strain's temperature preferences is fundamental to cultivation planning, as deviations can affect phenotype expression, terpene profiles, and overall pla

Breeders working with temperature-sensitive genetics deliberately cross plants from contrasting climates to expand or narrow thermal tolerance, depending on target market conditions. Temperature stability is also a key selection criterion when developing cultivars for specific regions or indoor farming systems with consistent environmental controls.
