Strong potency and a sweet taste make this cannabis classic pleasant and satisfying—a one-of-a-kind cultivar that's earned every merit badge there is. Top Leaf prides itself on carefully crafted cannabis—cultivars with rich, full-bodied flavour and complex terpene profiles—grown to exacting standards in the heartland of Alberta. These vape products are made using broad-spectrum extraction and glass/ceramic carts (.5 g, standard 510 thread), preserving each strain's natural cannabinoids, terpenes and flavour.

Anyone can grow some weed, but Top Leaf isn't "anyone" and we don't grow "some" weed. We were founded by cannabis enthusiasts under a simple guiding principle: "What do we want to smoke?" The answer is easy. We want the best. We want rich, full-bodied cannabis, with complex terpene profiles, mid-to-high THC potency and that little something special that makes you say "Wow" the first time you take a puff.

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. 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.
