Introduced in 2003 by Ken Estes, Granddaddy Purple (or GDP) is a famous indica cross between Purple Urkle and Big Bud.

Categories: , SKU: D103 Tag:



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. Original Grand Daddy Purps ancestors have grown in the hills of Northern California for over two decades, where her phenotypes have been known by many different names including Grape Ape, Purple Erkel, and Grandaddy Grape Ape. GDP flowers bloom in shades of deep purple, a contrastive backdrop for its snow-like dusting of white crystal resin. Granddaddy Purple has taken first prize in no less than four pot competitions: The Inglewood Medical Cannabis Cup in 2004, and the Green Cup in 2004, 2005, and 2006.

Growing Information

As an indoor crop, Granddaddy Purple is equally happy in hydro or soil. With a pure Indica heritage, this plant is predisposed to short bushy stature. Granddaddy branches extensively, making her less than ideal for SOG style grows, but she can be trained to make an awesome super crop garden. When left to her natural tendencies, this strain will make a nice big shrub that reaches about 3 feet indoors or up to 8 feet outdoors. She is a hardy grower with tight internodes and dense dark green to purple leaves.

Flavor and Effects

There is a potent, undeniable grape tinge to this plant’s aroma and a sweet grape taste that lingers subtly on the tongue. Its potent psychoactive 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. Like most heavy Indica varieties, Granddaddy Purple is typically pulled off the shelf to treat pain, stress, insomnia, appetite loss, and muscle spasms.
