Granddaddy Purple, often referred to as GDP, is an indica cannabis strain with several variations. First introduced in 2003 by Ken Estes, this well-known strain is a cross between Mendo Purps, Skunk, and Afghanistan. Granddaddy Purple’s powerful effects are felt both mentally and physically, offering a blend of cerebral euphoria and deep relaxation. While your mind may drift into a dreamy haze, your body is likely to feel deeply settled, staying relaxed in one place for the duration of the strain’s effects. GDP is frequently chosen by those seeking relief from pain, stress, insomnia, appetite loss, and muscle spasms.
