Frequently asked questions
What are fast-flowering seeds?
Fast-version seeds are photoperiod strains bred to flower faster than the standard version, shaving roughly one to two weeks off flowering while keeping photoperiod control.
Are fast-flowering seeds the same as autoflower?
No. Autoflowers switch to flowering by age regardless of light. Fast versions still flower on a light schedule but finish sooner than the standard photoperiod strain.
How much do fast-flowering seeds cost?
Fast-version packs are usually priced similarly to standard feminized seeds, commonly $12 to $40 from verified US-facing retailers.
