Diurnal Temperature Range
Diurnal temperature range (DTR) refers to the difference between daytime highs and nighttime lows during a plant's growth cycle. In cannabis cultivation, DTR influences terpene synthesis, cannabinoid development, and overall plant metabolism. Lineage records and breeding notes frequently document how specific environments—particularly those with larger day-night swings—correlate with terpene profiles in offspring. Breeders working with controlled environments monitor DTR as an environmental variable that can shape volatile compound expression without altering genetic material itself. Understanding DTR is crucial for stabilizing phenotypes across growing conditions.

Breeders use controlled DTR to select for consistent terpene expression and plant vigor under variable climates. Strains developed in regions with pronounced temperature swings often show adaptive traits that breeders seek when establishing photoperiod-stable or climate-resilient genetics.
