Fast Flowering Seeds
Fast flowering seeds are feminized, photoperiod strains bred to finish in as little as 6-7 weeks, weeks faster than a standard strain. You get all-female, bud-producing plants plus a shorter flowering time, ideal for quick turnarounds and short outdoor seasons. Every seed has a 99% germination guarantee with fast, discreet US shipping.
Why Choose Fast Flowering Cannabis Seeds?
Fast-flowering strains are bred to finish their flowering stage quickly, usually in 45 to 60 days, so you harvest sooner. That includes both autoflowers and photoperiod 'fast version' strains like Gelato Fast Version and Bruce Banner Fast Version. Faster cycles mean better efficiency, less risk from bad weather and, outdoors, the chance to finish before the cold sets in. And because they are feminized, there are no males to spot and remove, which saves time and boosts your final yield. We stock fast sativa, indica and hybrid options across a range of THC levels.
What Are Fast Flowering Seeds?
Fast flowering, or 'fast version', seeds are hybrids crossed with autoflowering genetics so they flower faster and need less time under long light, finishing in around 6-7 weeks versus up to 10 for a regular strain. They are also hardy and easy to grow, which makes them great for beginners. The trade-off: fast versions sometimes carry slightly less THC than the original photoperiod strain, which some growers actually prefer for a milder, more manageable effect. Give them steady water, light and nutrients and they reward you with quick, resinous harvests.
Pros and Cons of Fast Flowering Seeds
Pros
- Faster harvest: a shorter flowering period means you harvest sooner and can fit more cycles per year.
- Easier to manage: quick finishes leave less time for mold, mildew and pests, great for beginners.
- Higher yields: many fast versions are bred to match or beat their slower parents for weight.
- More adaptable: they handle tougher climates and shorter seasons well.
Cons
- Slightly less THC: some fast versions carry a little less THC than the original strain.
- Fewer breeding options: as stabilized hybrids, they are less suited to creating new crosses.

How to Grow Fast Flowering Seeds
Fast flowering strains are photoperiod plants, so they start flowering when you cut the light cycle to about 12 hours of darkness indoors, or when the days shorten outdoors. The difference is speed: most finish flowering in around 6 to 7 weeks instead of the usual 8 to 10. Give them a short vegetative stage, steady feeding and good airflow, and they stay compact and easy to manage. Outdoors they shine in cooler or shorter-season climates, where finishing early means harvesting before the autumn rain and mold arrive. Beginners do well with them because there is simply less time for problems to build up.
Fast Version vs Autoflower vs Regular Photoperiod
All three finish at different speeds. A regular photoperiod strain gives the biggest plants and yields but takes the longest and needs a light-cycle change to flower. An autoflower flowers automatically with age, finishes fastest and stays small, ideal for total simplicity. Fast version sits in between: it flowers on a light change like a photoperiod, but weeks quicker, and usually yields more than an autoflower. Choose fast version when you want most of a photoperiod's harvest with much of an autoflower's speed.
FAQs
What are fast flowering seeds?
Fast flowering seeds are feminized, photoperiod strains crossed with autoflower genetics so they finish faster, often in 6-7 weeks instead of up to 10. You get all-female plants and a quicker harvest, ideal for short seasons or growers who want a fast turnaround.
What is the difference between fast version and autoflower seeds?
Fast version strains are photoperiod plants: they still flower when you cut light hours, just faster than usual, and often yield more. Autoflowers flower automatically with age and finish fastest but stay smaller. Choose fast version for bigger harvests with speed, autos for total simplicity.
What are the fastest flowering strains?
Some of our quickest fast versions finish in around 6-7 weeks, including Bruce Banner Fast Version, Critical Fast Version and White Widow Fast Version. Exact timing depends on the strain and conditions, so check each product page for its flowering time.
Are fast flowering seeds good for outdoors?
Yes, especially in cooler or shorter-season climates. Their quick flowering lets you harvest before autumn cold and damp set in, which lowers the risk of mold. They are also hardy and forgiving, a solid choice for outdoor and first-time growers.
How long do fast flowering seeds take from seed to harvest?
Most finish in roughly 9 to 11 weeks total: a short vegetative stage plus about 6 to 7 weeks of flowering. Autoflowers can be a little quicker, and regular photoperiods take longer. Exact timing depends on the strain and your setup, so check each product page.
Do fast flowering seeds yield less?
Not necessarily. Many fast versions are bred to match or nearly match their photoperiod parents, so you trade a little time for a lot of speed rather than a big drop in weight. Yield depends most on your light, space and training, whatever strain you grow.
