Girl Scout Cookies strain: every version compared

Which Girl Scout Cookies should you grow?

With GSC, the choice is mostly height and timing: strength is high across every version, so let that be a given.

Photoperiod or autoflower? Photoperiods give the full plant, run on a timer across 49–67 days, and list top THC of 22–29%. Yields are close; the biggest listed figure, 650 g/m², is shared by three autos and one photoperiod. Autoflowers finish on their own clock from seed, 55–77 days, at 20–26%. For a first grow, an auto takes the timing worry away.

Feminized or regular? With feminized seed every plant is a female, so a first grow skips the sexing step. BC Bud Depot's regular GSC is here too, for breeding or taking cuttings.

Girl Scout Cookies photoperiod (feminized and regular)

The photoperiod versions are the full GSC: run on a timer, 18 hours of light to grow and 12 to flower, and you get sweet, minty flower. Flowering runs 49–67 days, with top listed THC 22–29%. Heights are listed at 120–140 cm.

Girl Scout Cookies autoflower

The GSC autos are the hands-off route into the strain: no light schedule to juggle, just a plant that flowers on age and finishes when it is ready. There are 7 autos here, and they keep the sweet, pungent GSC character while trimming the plant down. Seed-to-harvest times run 55–77 days. Heights are listed at 100–120 cm, and listed THC on the autos still sits in the twenties, 20–26%. Most autos list Ruderalis or an auto line in the cross to set the clock without losing the character. If you are new to growing and want GSC's strength and flavour without a light schedule, start here.

How Girl Scout Cookies grows

Girl Scout Cookies stays medium and well-mannered: heights across the versions run 100–140 cm, a tight band, so height is rarely the problem here.

Speed is where the versions pull apart. Herbies run two feminized cuts far apart: the Fast Version at 52 days, which they rate quick-maturing and productive like an indica while staying reasonably compact, and the standard cut at 67. The autos run on a different clock: Fast Buds list theirs at 63 days from seed and call it a sound first autoflower that trades a little of the photoperiod's ceiling for the ease of the automatic timetable, no light-schedule juggling required, while Herbies list their auto at 641 g/m² and 100 cm. Blimburn's auto is listed at 56 days from seed and 110 cm.

The yields are the headline across the board: several versions are listed at 600 g/m² or more. Barney's list their feminized line at 60 days and 120 cm, call it a rewarding grow for the strength on offer, and sum it up as little to fault and a great deal to like. That weight is worth planning for, and they add that she fills out best with even light across the canopy and consistent care. Original Sensible list their feminized at 140 cm, the tallest here. Blimburn list their auto at 110 cm.

Where Girl Scout Cookies comes from

Girl Scout Cookies is a modern name with an outsized reputation, and the catalogue mostly agrees on the make-up. The best-known telling crosses OG Kush with Durban Poison: the OG Kush bringing the weight and resin, the Durban the spark and the sweetness, as Barney's Farm put it. Garden Of Green and BC Bud Depot list an extended lineage with Cherry Kush folded in. Breeders quote her indica-leaning on balance, usually around 60/40, though the exact ratio varies. It is a young name next to the landraces, but one that has seeded a great many crosses since. Where the breeders word it differently, we report each one and leave the verdict to you.
