Description
Born from a cross of Sweet Seeds' own Green Poison and Green Poison Auto, this indica-dominant feminised variety carries the best of both parents. The aroma profile is layered and distinctive, opening with ripe fruit before giving way to classic skunk and a warm, spicy undercurrent. Effects sit firmly in high-THC territory at 16-24%, with the relaxing character typical of indica-leaning genetics.
In the garden, Green Poison F1 Fast Version is a grower's reward. Medium plant height keeps it well-suited to indoor tents and confined grow rooms, where yields of 450-600 g/m2 are well within reach. Outdoor plants can be generous to an even greater degree, with per-plant yields of 450-750 grams for those with suitable conditions. The real headline is the flowering window: 5 to 7 weeks is unusually swift, allowing indoor growers to run more cycles per year and giving outdoor cultivators a meaningful buffer before autumn sets in. Feminised genetics remove the guesswork, making this an accessible and productive choice for cultivators at any experience level.

about this product
Green Poison F1 Fast Version brings Sweet Seeds' signature fruity-skunky potency to harvest in just 5 to 7 weeks, ready for growers who want big yields without the wait.
Sweet Seeds has rated this strain as easy to grow, and its indica-dominant structure keeps things manageable with a medium, compact height that fits comfortably in a tent or small grow room. The fast-finishing nature also means less time for things to go wrong, which is a genuine advantage when you're still finding your feet.
Flowering time sits at just 5 to 7 weeks, which is unusually quick for a feminised photoperiod strain — that speed comes directly from the Green Poison Auto genetics crossed into the lineage. It means you can realistically run more cycles per year compared to standard-flowering varieties.
Indoor growers can expect 450 to 600 grams per square metre under optimised conditions, which puts it firmly in the high-yield category. Outdoor plants have even more headroom, with per-plant returns of 450 to 750 grams when given space and a good season.
The aroma opens with ripe, tropical fruit before settling into a classic skunky base with a warm spicy edge underneath — it's a layered profile that gives it real character rather than a one-note hit. That same complexity carries into the flavour, making the smoke or vapour as interesting as the grow itself.
