Granddaddy Purple is the king of purple strains and arguably the most famous indica in America. Ken Estes introduced it to the California medical scene in 2003, and it quickly became the go-to recommendation for insomnia and pain patients. The deep purple buds, grape candy aroma, and reliable sedation made it an instant classic. It's the strain that taught America that indicas are for nighttime.

Duration

Indicated window
Nighttime only. This is a sleep strain, period. 1-2 hours before bed is ideal.
GDP is a one-way ticket to the couch and then to bed. The high begins with a dreamy, floaty euphoria — the world softens and everything feels warm and comfortable. Then the indica side takes over completely. Your body becomes heavy, your eyelids droop, and sleep comes naturally. This is THE sleep strain. The grape candy flavor makes it feel like dessert before bed.

Notes
One of the most beautiful cannabis plants — deep purple buds with orange hairs and frosty trichomes. Cold temps in the last 2 weeks of flower intensify the color. Easy to grow, hard to mess up. Big Bud genetics mean generous yields.
