Pyramid Seeds knows that every day counts. That’s why we created a dedicated category for fast flowering feminized seeds: carefully selected genetics designed to deliver faster harvests without sacrificing quality, potency, or flavor. If you’re looking for fast growing cannabis seeds — fast flowering feminised seeds that finish about a week earlier and still deliver full photoperiod yields — you’re in the right place.
Fast Version seeds from Pyramid Seeds — feminized seeds with germination guarantee for anyone who wants maximum speed without losing quality. Flowering times of 43 to 58 days under LED, THC up to 27%, yields up to 1000 g/1.5 m². Photoperiod genetics with a shortened flowering phase — the best of both worlds.
Fast Version seeds are created by crossing classic photoperiod strains with selected autoflower lines. The result: the plant flowers much faster than the original — yet keeps its full photoperiod character: full control over the vegetative phase, full potency, full yield potential.
Also known as fast flowering seeds, fast version seeds or early version — ideal for indoor growing with several cycles per year, and for outdoor growing in short-season, temperate climates where the season is brief. Note: Fast Version is not autoflower — it's photoperiod genetics that simply finishes sooner.

Fast Version seeds are created by crossing classic photoperiod strains with autoflower genetics. The result: a much shorter flowering time with the original strain's character fully preserved — same potency, same yield, same aromas.
When growers search for fast growing cannabis seeds or fast growing weed seeds, they usually mean one of two things: Fast Version photoperiod seeds like the strains in this category, which shorten flowering by about a week while keeping full yields, or autoflowering seeds, which run the whole cycle from seed without a light change. All our Fast Version strains are feminized — “feminised” in British spelling.
The Fast Version strains by Pyramid Seeds flower in 43 to 58 days under LED, depending on the strain. Gorila Fast is the fastest at 43 days, Wembley Fast at 45 days, Tutankhamon and Super OG Kush Fast at 48 days, Kryptonite Fast at 53 days.
Fast Version strains are photoperiod — they need a switch to 12/12 to flower and offer full control over the vegetative phase. Autoflowering strains flower automatically with no light schedule. Fast Version usually delivers higher yields and potency than the corresponding auto version.
No. Fast Version strains keep the same THC content as the original strain. Gorila Fast reaches up to 27% THC, Tutankhamon Fast up to 26% — identical to the feminized versions.
Yes — especially well suited. In short-season, temperate climates, the risk of autumn damp and mould rises from September. Fast Version strains allow an earlier harvest (August to mid-September) and greatly reduce that risk.
Gorila Fast reaches the highest at 25–27% THC among the Fast Version strains by Pyramid Seeds. Tutankhamon Fast follows at up to 26% THC, Super OG Kush Fast at 24–26% THC.
