Granddaddy Purple (or GDP) is a famous indica cross between Purple Urkle and Big Bud. This California staple inherits a complex grape and berry aroma from its Purple Urkle parent, while Big Bud 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. This strain is great for insomnia.
