GSC, which was originally known as the Girl Scout Cookies strain, was first bred by Northern California’s Cookie Family sometime about 2012. A Sativa-leaning hybrid cross between a cutting of OG Kush and the breeder’s own F1 Durban Poison strain, GSC produces a plant with multiple branches and a powerful flower. The strain has a short stature that is common on strains with Indica lineage and is known for its tight internodal structure, which creates its iconic spear-shaped flowers with lavender calyxes.
When cultivated indoors, GSC’s flowering time is approximately 62-71 days after switching the light cycle from veg to flower. Outside, growers will need to wait until mid-October in the Northern Hemisphere, mid-April in the Northern Hemisphere, for harvest. Regardless of wherever GSC is cultivated, the plant wants to grow tall and requires training, pruning, and full exposure to light to reach its maximum yield potential.
The most popular phenotype produced by the first batch of GSC seeds was Thin Mints.
GSC has taken home several High Times Cannabis Cup awards since it was first propagated — including a first-place trophy for Best Hybrid at the 2013 Southern California Cannabis Cup.
