Finishing Time Extended Finish

Extended Finish refers to cannabis cultivars that require longer flowering periods than typical photoperiod varieties, generally 10-14 weeks or more from flower initiation to harvest maturity. This classification encompasses both naturally longer-blooming genetics and cultivars intentionally bred to extend the ripening window. Breeders working in this category often select parents with delayed senescence or complex terpene/cannabinoid development curves. Extended finish varieties are commonly associated with certain landrace lineages and modern crosses designed for enhanced secondary metabolite accumulation. Documentation of precise finishing windows is critical for production planning, as these genetics demand extended greenhouse occupancy and resource allocation.

Breeders utilize extended-finish genetics to create cultivars with purportedly more complex flavor profiles and specific cannabinoid ratios that benefit from prolonged maturation. Selecting parents with delayed maturity allows breeder programs to fine-tune harvest timing for target phenotypes.
