Fast version cannabis seeds are feminized seeds created by crossing a photoperiod strain with a faster-finishing (often ruderalis-influenced) parent, which shortens the flowering stage with photoperiod light dependency intact.
These fast-flowering seeds trim roughly 1–2 weeks off the usual flowering time while still requiring a light-cycle change to trigger flowering — which means bigger yield potential, more control (for indoor growers) and faster harvests. Since they’re feminized, these seeds produce female cannabis plants so growers skip the work of removing male pot plants.
Fast version seeds finish flowering in about 6–8 weeks after the flip to 12/12 indoors, or when nights get longer outdoors. That makes them some of the fastest flowering strains you can grow with full light control. Standard photoperiod feminized seeds often run 8–10 weeks, so fast-flowering cannabis seeds cut 1–2 weeks off the back end of the grow.
Exact timing shifts with genetics, light and feeding. A shorter bloom window means less time exposed to pests and mold, lower running costs indoors, and the option to fit more grows into a year.
Fast version cannabis seeds fit three grower types whose plans depend on a shorter time to harvest.
Speed-focused indoor growers choose fast version seeds because a 6–8 week flower means more grows in less time. Shorter flowering also reduces equipment costs and the time plants spend exposed to pests and mold. These fast-flowering seeds give you full photoperiod control, so you still decide exactly when to flip to 12/12.
Short-season outdoor growers choose fast version seeds because the harvest lands earlier, before cold and damp set in. A faster finish helps in northern states and high-altitude spots where the outdoor window is tight. Indica seeds in the fast version category often suit these conditions well, so growers can compare options for short, sturdy and fast-growing plants.
Fast versions are considered beginner-friendly weed seeds because they’re feminized and the grow is shorter, which lowers two common sources of frustration. Feminized genetics mean no male cannabis plants to identify and cull, and the quicker flower means less time for a first-time mistake to compound.
Fast version seeds, autoflowering seeds and standard feminized seeds share the same goal of producing female cannabis plants but differ in how flowering is triggered and how fast it finishes. The table below compares the three on their most important attributes:

Fast version seeds sit between the two: they finish faster than standard feminized photoperiod seeds but keep the light-cycle control that autoflowers give up.
Yes, Homegrown Cannabis Co. ships fast-flowering feminized seeds from a US-based distribution hub, so growers can order pot seeds online without an international wait.
Federal, state and local laws determine whether a grower can purchase, possess, germinate or grow cannabis seeds in a specific location. Growers are responsible for confirming their own eligibility before placing an order.
A few fast version or fast-flowering strains can finish closer to 6 weeks in flower, but most land in the 6 to 8 week range. Exact flowering time depends on the strain, light and feeding, so treat 6 weeks as an outlier rather than the norm.
Yes, fast version seeds have the potential to reach harvest within roughly 90 days from germination, counting a short veg plus a 6–8 week flower. The total depends on how long the plant vegetates beforehand, since a longer veg pushes the date back.
The fastest-growing plants in the fast version category include Big Bud Fast Version, Cinderella 99 Fast Version and OG Kush Fast Version. Growth speed during veg also depends on environment, pot size and feeding, so genetics set the floor but conditions set the pace.
No, fast version seeds are feminized photoperiod seeds with shortened flowering, not autoflowers. Fast versions still need a light-cycle change to start flowering, while autoflowers begin flowering on their own based on age.
