Granddaddy Purple (GDP) is an indica-dominant cannabis strain, commonly listed as roughly 80% indica and 20% sativa, with THC content that generally tests between 17% and 23%. It was bred by Ken Estes in the San Francisco Bay Area in 2003 by crossing Purple Urkle with Big Bud. The strain is known for dense purple flowers, grape and berry aromas, and a heavy, relaxing body effect.

What is the Granddaddy Purple strain?
Granddaddy Purple, also written Grand Daddy Purp or simply GDP, is a California legacy cultivar that became a benchmark for purple indicas. Its lineage pairs Purple Urkle for color, flavor, and sedation with Big Bud for yield and resin production. Shoppers in legal US markets find it as flower, pre-rolls, and vape cartridges.

Is Granddaddy Purple an indica or sativa?
It is indica-dominant. Most seed-bank and dispensary listings place the ratio near 80% indica and 20% sativa, so the experience leans toward the body rather than the head. That label reflects plant structure and reported effects, not a strict chemical rule.

What does Granddaddy Purple feel like?
Effects tend to arrive as a warm pressure behind the eyes and a slow full-body relaxation that can make movement feel heavy. Many consumers describe euphoria and calm first, followed by sleepiness as the high settles. High-THC batches can feel strongly sedating, so new users should start with a small amount.

How long do Granddaddy Purple effects last?
Inhaled effects generally last two to three hours, depending on dose, tolerance, and THC level. Edibles made with GDP can last longer and hit harder because the liver converts THC into a more potent metabolite.
THC, CBD, and terpenes
THC levels usually land between 17% and 23%, and some premium batches test above 25%. CBD content is low, often under 1%. Myrcene leads the terpene profile, with caryophyllene and pinene behind it.
What does Granddaddy Purple smell and taste like?
- Grape and berry candy sweetness
- Earthy, spicy, sometimes hashy notes
- A sweet herbal exhale
Anthocyanins, the same pigments found in blueberries, create the purple and violet color when flowers ripen in cool nighttime temperatures.
Growing Granddaddy Purple at home
GDP is a photoperiod indica that finishes flowering in about 8 to 11 weeks indoors. It stays short and bushy, responds well to low-stress training, and produces dense, resinous buds with above-average yields. Cooler late-flower temperatures near 65 F bring out the deepest purple hues.
Who should try Granddaddy Purple?
It suits experienced consumers who prefer a calm, evening-oriented high and fans of grape-forward indica flavor. Beginners should treat it as a potent strain and moderate the dose. Anyone in the US must be 21 or older, or a registered medical patient, and should buy only from licensed retailers. Effects vary by person, and no cannabis strain is a proven treatment for any condition.
