Generation Time
Generation time refers to the duration required for a cannabis plant to complete one full lifecycle from seed germination to mature seed production. In breeding contexts, this metric encompasses vegetative growth, flowering, and seed maturation phases—typically ranging from 60 to 120+ days depending on photoperiod sensitivity and genetic background. Breeders track generation time as a practical measure for timeline planning, selection intensity, and the feasibility of multi-generational improvement programs within a single growing season. Shorter generation times enable faster iteration in breeding cycles, while longer cycles may allow for more developed phenotype expression and larger seed harvests per generation.

Breeders prioritize generation time when designing selection programs, as faster cycles allow more generations of trait refinement annually. Photoperiod-sensitive varieties typically have longer generation times than day-neutral or autoflowering lines, influencing decisions about breeding methodology and geographic growing location.
