Strain Highlights

Introduced in 2003 by Ken Estes, 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. GDP flowers bloom in shades of deep purple, a contrastive backdrop for its snow-like dusting of white crystal resin.

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. GDP blesses growers with massive commercial yields which are ready for harvest following a 60 day flowering time indoors.

“I tried Granddaddy Purple for the first time yesterday. I'd looked forward to trying it all week after reading these reviews. Seriously, I think I was MORE excited to try the strain than a kid looks forward to Christmas. The taste is so sweet. The smoke is thick and heavy with the sweet under taste. Nice! 5 minutes later....nothing. No effects whatsoever. 10 minutes in, my only effect was boredom. No! 15 minutes in...”

“I have PTSD which causes panic/anxiety attacks with depression. I have tried a few others and they did not work too well and a couple even caused an anxiety attack. But this one works like a charm. Usually will take a couple of hits when I get home from work and can feel the stress go away and my mood improves. Will make you a little sleepy though but not too bad.”
