Jack Herer was created in the Netherlands in the mid-1990s, where it was later distributed by Dutch pharmacies as a recognized medical-grade strain. Since then, the spicy, pine-scented sativa has taken home numerous awards for its quality and potency. Many breeders have attempted to cultivate this staple strain themselves in sunny or Mediterranean climates, and indoor growers should wait 50 to 70 days for Jack Herer to flower.

Green Crack has branched into two genetic lineages, the most common of which is its sativa line descended from Skunk #1. The 75% indica variety of Green Crack is said to have come from an Afghani strain, and is marked by a tighter bud structure. Because its name perpetuates a negative image of cannabis, some people have taken to calling this strain Cush (with a ‘C’) or Green Cush instead.
