Grandaddy Purple is an indica-dominant cannabis strain with many different names, including ‘Grand Daddy Purp’, ‘Granddaddy Purps’, ‘GDP’ and ‘Granddaddy Purple Kush’. Granddaddy Purple (or GDP) is a famous indica hybrid of Mendo Purps, Skunk and Afghanistan.

– Indica-dominant hybrid with rich history
– Powerful, relaxing cannabis strain
– Recommended to use growing techniques
– Short flowering time of 8-9 weeks

Grandaddy Purple grows best indoors but can also be grown outdoors. The extra large buds may start to burden the plant, especially if grown outdoors. If grown indoors, the plant should be short and stocky enough to support the weight, growing techniques like LST, SoG or ScroG are recommended.

Grandaddy Purple hits both body and mind initially, but quickly fades into a smooth physical haze as most heavy indicas do. She induces the classic indica couch-lock feeling.
