London Purpz is an indica-dominant hybrid with a somewhat murky family tree. The strain is thought to be a cross between London Pound Cake and Mendo Purps, two cultivars with strong indica genes. London Pound Cake is a child of the famed strain Sherbert and a grandchild of the iconic GSC strain. Its ancestors include Hindu Kush, Chemdog, and Durban. Despite its sativa roots, London Pound Cake’s indica-leaning kush background outshines all. Mendo Purps is a classic Emerald Triangle strain that first hit the scene in the mid-'00s, named High Times’ strain of the year in 2007. It’s thought to be a descendant of indigenous North American indica landrace genetics. Mendo Purps is known for its grape flavor and full-body effects. With a family tree that crisscrosses back and forth, London Purpz jam-packs some of the world’s most fantastic cannabis genetics in one supercharged cannabis strain. But with so many strains in one, what exactly is the chemical makeup of London Purpz?
