Granddaddy Purple (GDP) — also known as Grand Daddy Purp, Granddaddy Purps, GDP, or Grandaddy Purple Kush — is a legendary Indica strain that’s been a California favorite since its debut in 2003 by cannabis breeder Ken Estes.

This iconic strain is believed to be a cross between Mendo Purps, Skunk, and Afghani, though some claim it descends from Big Bud and Purple Urkle. Either way, GDP stands out with its signature grape and berry aroma, inherited from its rich Purps and Afghani lineage.

Visually striking, GDP buds bloom in deep shades of purple, contrasted by a thick layer of shimmering white trichomes. The effects are unmistakably powerful — a blend of euphoric mental elevation and full-body relaxation. While your mind drifts into a calm, dreamy state, your body often sinks into stillness, making GDP ideal for evening or nighttime use.

Known for its therapeutic benefits, Granddaddy Purple is commonly used to relieve pain, stress, insomnia, appetite loss, and muscle spasms. Growers also love GDP for its heavy yields and relatively quick flowering time of around 60 days indoors.
