About Granddaddy Purple

One of the most famous and beloved cannabis strains available, Granddaddy Purple (AKA GDP) is an indica-dominant blend of Purple Urkle and Big Bud that combines the best of these two lovely strains.

Known for producing profound psychedelic effects, delivering all-encompassing euphoria and a physically sedative effect that leaves its user totally relaxed and often sleepy.

THC levels of this prolific strain are variable, but generally tend to be around 20%, though they can be much higher depending on the quality of care Granddaddy Purple received as it was growing.

Grandaddy Purple's buds are, obviously, a bright eggplant color, and each dense, chunky bud is encased in a layer of swirling orange pistils and glistening trichomes, and these flowers produce a delicious flavor of ripe berries and grape.
