What Are Fast Version Cannabis Seeds?
Fast version cannabis seeds are photoperiod-dependent feminized seeds bred to flower significantly quicker than standard feminized strains — typically finishing in six to seven weeks of bloom rather than the usual eight to ten. They are created by crossing an autoflowering variety with a classic photoperiod strain, then stabilizing the offspring so it inherits the rapid flowering of the auto parent while retaining the structure, yield potential, and cannabinoid profile of the photoperiod parent.
The key distinction: unlike , which flower automatically based on age, fast version seeds still respond to light cycle changes. You flip them to a 12/12 schedule to trigger flowering — they just race through it. That makes them a versatile middle ground between and autoflowering seeds, and an especially smart pick for Canadian growers working with a shorter outdoor season.
Why Grow Fast Version Strains?
Faster Harvests Without Sacrificing Yield Standard feminized photoperiods can take eight to ten weeks of flowering; fast version genetics compress that to as little as six weeks. You keep the bud size and plant structure of a photoperiod strain while shaving valuable time off the finish.
Ideal for Canadian Climates Outdoor growers in Canada face a narrow window before early frost. Fast version seeds reduce the risk of weather wiping out a late-finishing crop, since they are ready to harvest by late September to early October instead of mid-to-late October.
Light-Cycle Control, Unlike Autos Because they are photoperiod-dependent, you decide when to flip them to flower. That means you can veg them longer for bigger plants, or flip early for a compact, quick run — flexibility that don't offer.
Same cannabinoid and Terpene Quality Fast version genetics inherit their potency, aroma, and effect profile from the photoperiod parent. You are not trading quality for speed — you are getting a faster finish on a strain that still delivers on THC, CBD, or terpene expression.

Fast Version Seeds — Frequently Asked Questions
What are fast version cannabis seeds? Fast version seeds are photoperiod-dependent feminized seeds bred to flower in approximately six to seven weeks — significantly faster than standard feminized strains, which typically take eight to ten weeks. They are created by crossing an autoflowering variety with a classic photoperiod strain and stabilizing the rapid-flowering trait.
What is the difference between fast version and autoflowering seeds? Autoflowering seeds flower automatically based on age, regardless of light schedule. Fast version seeds still require a light cycle change (12/12) to trigger flowering — they just move through bloom faster. That means you can control plant size by adjusting veg time, which you cannot do with autos. Compare both options in our .
Are fast version seeds good for outdoor growing in Canada? Yes — they are an excellent fit for Canadian outdoor grows. Because they finish faster than standard photoperiods, they are ready to harvest by late September to early October, reducing the risk of frost or weather damage. That timing advantage is one of the main reasons Canadian growers choose fast version genetics.
Do fast version seeds produce less than regular feminized seeds? Yield is comparable to standard feminized seeds and typically higher than autoflowering varieties. Because fast version plants still grow under a photoperiod light schedule, they develop full-sized plants with strong lateral branching — the trade-off is a slightly faster finish, not a smaller harvest. See our for a deeper comparison.
Can I grow fast version seeds indoors? Absolutely. Indoors, fast version seeds let you run more harvest cycles per year since each bloom phase is shorter. Switch to 12/12 lighting to trigger flowering, and expect harvest-ready buds in roughly six to seven weeks of bloom.
