Granddaddy Purple is an indica marijuana strain. Popularized in 2003 by Ken Estes, Granddaddy Purple (or GDP) is a famous indica cross of Mendo Purps, Skunk, and Afghanistan. Other people claim it is Big Bud x Purple Urkle. Either way, this California staple inherits a complex grape and berry aroma from its Purps and Ghani heritage. GDP flowers bloom in shades of deep purple, a contrasting backdrop for its snow-like dusting of white crystal resin. Its potent effects are clearly detectable in both mind and body, delivering a fusion of cerebral euphoria and physical relaxation. While your thoughts may float in a dreamy buzz, your body is more likely to find itself fixed in one spot for the duration of GDP’s effects.
