Diurnal Temperature Variation
Diurnal temperature variation (DTV) refers to the daily fluctuation between daytime highs and nighttime lows experienced by cannabis plants during cultivation. This environmental cycle—typically 8–15°C swings in controlled settings—influences plant physiology, including nutrient uptake, transpiration rates, and secondary metabolite accumulation. Breeders and cultivators often manipulate DTV to stress-test genetics or optimize terpene and cannabinoid expression without chemical inputs. While not a terpene itself, DTV is frequently studied alongside volatile organic compound (VOC) profiles because temperature shifts can trigger or suppress synthesis of limonene, myrcene, pinene, and other aromatics. The relationship between temperature cycling and chemotype stability remains an active area of horticultural research.

Breeders use controlled DTV regimens to identify genotypes with stable secondary metabolite profiles across varying environmental conditions. Deliberate temperature stress during flowering is a common selection criterion for lines intended for outdoor cultivation or inconsistent climate zones.
