Granddaddy Purple is an indica marijuana strain that goes by many different names including "Grand Daddy Purp " "Granddaddy Purps " "GDP " and "Grandaddy Purple Kush." Popularized in 2003 by Ken Estes Granddaddy Purple (or GDP) is a famous indica cross of Mendo Purps Skunk and Afghanistan. This California staple inherits a complex grape and berry aroma from its Mendo Purps and Afghanistan parent while Skunk passes on its oversized compact bud structure. 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.
