Granddaddy Purple, also known as Grandaddy Purp or GDP, is a hybrid that was first propagated in Northern California in 2003 by breeder Ken Estes. A cross between Purple Urkle and Big Bud, GDP was then backcrossed into itself.

Granddaddy Purple has an average THC content of roughly 17 percent, and is typically high in Caryophyllene, alpha-Pinene, and Humulene. Like most indicas, this strain has been reported to help you relax and sleep, making it perfect for day or nighttime.

A genetic winner, GDP’s buds won first place in 2015 at the Denver High Times Cannabis Cup for Best U.S. Indica.
