About Granddaddy Purple
Granddaddy Purple was created by Ken Estes of the Bay Area and singlehandedly established 'purple weed' as a commercial category. By crossing the color and flavor of Purple Urkle with the yield and structure of Big Bud, Estes created a strain that was as beautiful as it was potent. GDP's deep purple buds (sometimes nearly black), heavy resin production, and sweet grape-berry aroma made it an instant icon. Its effects are powerfully sedative, making it a staple for insomnia and pain relief patients.

History

The strain won multiple High Times Cups and became the definitive purple strain. It was among the first strains to prove that color could drive consumer preference as much as potency or flavor.
