Quickest Harvest Cannabis Strains — Seed to Harvest

Flowering time is only part of the equation. What actually matters for planning your calendar is total time from the day you germinate to the day you chop. Autoflowering genetics dominate this metric, with the fastest examples going from seed to harvest in just seven to eight weeks, compared to fourteen to twenty weeks for typical photoperiod strains including vegetative time. This total-time metric matters whether you are fitting multiple grows into a year, planning around an outdoor weather window, or simply want to know when your grow will be done. Every strain on this page is ranked by total seed-to-harvest time using breeder data cross-referenced with community grow reports that record actual germination and harvest dates, giving you reliable figures rather than optimistic minimums.
