Granddaddy Purple (or GDP) is a famous indica cross of Purple Urkle and Big Bud. This California staple inherits a complex grape and berry aroma from its Purple Urkle. 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.
