What is the Girl Scout Cookies strain?
Girl Scout Cookies autoflower is GSC crossed with Cannabis ruderalis, so the plant begins to bud by itself once it is three or four weeks old instead of waiting for shorter days. Autoflower GSC listings describe an indica-leaning plant (about 60% indica) that tops out between 60 and 100 cm and is harvested roughly 9 or 10 weeks after sowing. Seed banks quote roughly 20 to 24% THC, a little below the photoperiod GSC, with the same sweet, earthy, minty flavor.
Ratio from Fast Buds' and MSNL's autoflower listings; the ruderalis share is not counted separately.
Autoflower GSC needs no change in light hours, and most plants are cut 63 to 70 days after germination.

Where does the Girl Scout Cookies strain come from?
The autoflowering Girl Scout Cookies strain comes from crossing the Bay Area hybrid GSC with Cannabis ruderalis, a hardy wild type that flowers by age rather than day length. GSC itself was made famous by the Cookie Fam in the late 2000s and is usually traced to OG Kush and Durban Poison; Fast Buds describes its own auto as a West Coast OG × Durban Poison base with Canadian ruderalis added.
Because the original GSC circulated as clone-only cuts, every autoflower version is a seed bank's own recreation, stabilized over several generations until the auto trait holds. Different breeders' GSC autos can therefore vary a little in height, aroma and timing, but the published versions agree on a short, indica-leaning plant that finishes in about 10 weeks.
How is GSC autoflower different from feminized GSC?
Girl Scout Cookies autoflower is smaller and faster than feminized GSC, and it does not need a 12-hour dark period to flower. The photoperiod plant grows as long as you keep it in vegetative light, then needs about 8 to 10 weeks of bloom, while the auto starts budding on its own and is usually done 9 to 10 weeks after sprouting. The trade-off is a fixed size and slightly lower reported THC.
No re-vegging. An autoflower cannot be held back as a mother plant or kept small by delaying bloom, so plan its pot size and space before you plant.

How do you grow Girl Scout Cookies seeds?
Girl Scout Cookies autoflower seeds make an easy, beginner-friendly plant: sow each seed where it will finish, run long light days (18/6 or 20/4) the whole time, bend rather than cut the stems early on, and expect to harvest around 9 to 10 weeks after germination.
- GerminateDays 1–7
Plant Girl Scout Cookies auto seeds directly into an 11 to 15 liter (3 to 4 gallon) pot; transplant shock costs an autoflower days it can't get back.
- Early growthWeeks 2–4
Bend the main stem gently with LST to open the canopy. Skip heavy topping on GSC autos, since recovery time eats into the short veg.
- FlowerWeeks 4–9
Pre-flowers show around week 4 with no light change. Keep lights at 18/6 or 20/4 and ease nutrients up gradually as buds stack.
- HarvestAbout week 9–10 from seed
Look at the trichomes through a jeweler's loupe and harvest once the heads turn milky; a few GSC autos want another week.
Grow tips for Girl Scout Cookies
- Pick the final pot first. Girl Scout Cookies autos only reach about 60 to 100 cm, and the pot is their main size lever, so choose it before you sow.
- Feed lightly early on. Autoflowering GSC seedlings are small and easy to overfeed; start at about half strength and raise it once flowers form.
- Train, don't cut. Low-stress training spreads GSC auto's branches for more even buds without the stall that topping can cause.
- Use a carbon filter in bloom. Fast Buds warns that its GSC auto smells strong late in flower, so indoor growers should filter the exhaust.
- Run more than one crop outdoors. Because GSC auto needs only about 10 weeks, outdoor growers in warm regions can fit two runs between late spring and early fall.
Is Girl Scout Cookies the right strain for you?
Great pick if you
- Want the sweet, minty GSC flavor without waiting for a long bloom
- Have only a low ceiling, such as a closet tent or a balcony
- Are a newer grower who wants a forgiving, easy plant
- Want a quick harvest or several outdoor runs in one summer
Think twice if you
- Want the biggest possible yield per plant (photoperiod GSC grows larger)
- Plan to clone it or hold a plant in veg for months
- Chase the very highest THC numbers reported for photoperiod GSC
- Prefer an energetic, purely daytime sativa high

Timothy Ransom –
Girl Scout Cookies is really fast flowering plant the reason why she’s really a small plant that her height doesn’t exceed to 3ft. However she has a strong stems and branches and her buds are just medium sizes. You need to take care to this plant because its prone to molds and pest. It produces a powerful earthy scent and effects that could makes you giggles in no time. Also it is good to those who suffer from depression.
