12 12 Flowering Protocol
The 12/12 flowering protocol refers to a light cycle of 12 hours on and 12 hours off, commonly used by cultivators to induce and maintain the flowering stage in photoperiod cannabis plants. This lighting schedule mimics the natural shortening days of autumn, triggering reproductive development in most photoperiod genetics. The 12/12 cycle is a standard in controlled indoor cultivation, though some breeders and growers experiment with variations (10/14, 11/13) to potentially influence flowering speed or morphology. Understanding photoperiodism is foundational to breeding work, as light cycles directly affect plant development timing and can influence trait expression across generations.

Breeders working with photoperiod lines rely on precise 12/12 scheduling to reliably flower test crosses and evaluate flowering phenotypes, node structure, and yield characteristics. Standardized lighting protocols enable consistent generational selection and help isolate genetic versus environmental factors in trait development.
