Jack Flash

Jack Flash is an award-winning cannabis hybrid bred by Sensi Seeds in the 1990s, created by crossing Jack Herer with Super Skunk and Haze. It won the 1998 Dutch High Life Cup and placed third at the 2004 High Times Cannabis Cup. Despite its indica-dominant genetics, it delivers a distinctly sativa-like cerebral high — fast-acting, euphoric, and creativity-enhancing — followed by a gradual body buzz. It features a pungent terpene profile of terpinolene, myrcene, and caryophyllene, producing earthy, citrus, and pine aromas with a spicy herbal flavor.
