Granddaddy Purple (GDP) is one of the most beloved indica-dominant hybrids out there—famous for its rich, fruity flavour, relaxing effects, and generous yields of dense, colourful buds. Bred from Purple Urkle x Big Bud, this 75% indica / 25% sativa photoperiod strain combines classic Cali purple genetics with old-school production power.

 

Purple Urkle (a Mendocino Purps phenotype) brings deep colour and dessert-style terps, while Big Bud contributes its Afghan/Skunk yield and structure. Together, they create a sturdy, low-maintenance plant that’s easy to grow and very rewarding in both tents and gardens.

 

Indoors, Granddaddy Purple seeds grow into compact plants around 2–4 ft tall, finishing in about 8–10 weeks of flowering and returning 16–19 oz/m² when dialed in. Outdoors, in short-summer or temperate climates, plants typically reach 4–5 ft and can yield 19–21 oz per plant, ready to harvest in early October.

 

With around 20% THC and low CBD, GDP delivers a deeply relaxing, body-focused stone that’s perfect for evenings and lazy nights in. Expect a mood-lifting, euphoric onset followed by a heavy, sleepy melt that makes it ideal as a nighttime strain. The terpene profile leans blueberry, fruity, and candy-sweet, with a hint of pine for extra freshness—true dessert vibes in bud form.
