Granddaddy Purple, also known as Grandaddy Purp or GDP, is a hybrid that was first propagated in Northern California in 2003 by breeder Ken Estes. A cross between Purple Urkle and Big Bud, GDP was then backcrossed into itself. The Granddaddy Purple high starts with a cerebral rush, filling you with euphoria and slight numbing sensation. Gradually, a heavy psychedelic effect takes hold, letting your mind drift vivid and trippy while your body sinks into deep relaxation and calm.
