Diurnal Temperature Differentials
Diurnal temperature differentials (DTD) refer to the daily fluctuation between daytime and nighttime temperatures in a growing environment. Cannabis cultivars exhibit varying phenotypic responses to these temperature swings, with some lineages historically developed in regions featuring pronounced day-night temperature variation. Breeders recognize that consistent exposure to moderate DTD—typically 10–15°C shifts—can influence terpene expression, cannabinoid ratios, and overall plant morphology across generations. Understanding how specific genetic backgrounds respond to DTD is relevant for indoor cultivation design, breeding program optimization, and strain stabilization in controlled environments.

Breeders working with landrace and heirloom genetics often select for DTD resilience or exploit temperature sensitivity to trigger specific terpene profiles. Stabilizing a cultivar's response to predictable temperature cycling requires multi-generational observation and environmental documentation.
