Granddaddy Purple is an indica marijuana strain that goes by many different names, including "Grand Daddy Purp," "Granddaddy Purps," "GDP," and "Grandaddy Purple Kush." This California staple inherits a complex grape and berry aroma from its Purps and Ghani heritage. 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.
