Granddaddy Purple
Read the ride before you spark it
Granddaddy Purple earns its DeePuff fit from 20% THC, a chill evening profile led by Linalool, and effects that lean calmer and more body-forward.
Introduced in 2003 by Ken Estes, Granddaddy Purple (GDP) is a famous indica cross of Big Bud and Purple Urkle. Its potent effects deliver a powerful physical relaxation and cerebral euphoria. GDP's iconic purple buds and grape-berry aroma make it one of the most recognizable strains in cannabis culture.
