The Girl Scout Cookies strain, also known as GSC, was created by the Cookie Family in Northern California around 2012. GSC is a sativa-dominant hybrid strain created by crossing an OG Kush cutting with the breeder’s own F1 Durban Poison strain. It results in a plant with numerous branches and a potent flower.
The strain is known for its tight internodal structure, which produces its recognizable spear-shaped flowers with lavender calyxes, and for having a short stature, which is typical of strains with Indica lineage. Thin Mints was the most well-liked phenotype created by the initial batch of GSC seeds.
Since it was first cultivated, GSC has won numerous High Times Cannabis Cup honors, including first place for Best Hybrid at the 2013 Southern California Cannabis Cup.
When grown indoors, GSC begins to flower 62–71 days after the light cycle is changed from vegetative to floral. Outside, harvest won’t be possible until mid-October in the Northern Hemisphere and mid-April in the same region. No matter where GSC is grown, the plant wants to become tall and needs training, pruning, and complete light exposure to produce its best yield.
