Strain Profile
Granddaddy Purple THCA Flower — widely known as GDP — is one of the most influential indica-dominant strains in the modern catalog, bred from Big Bud crossed with Purple Urkle. The cultivar is known for its deep purple bud expression, oversized flower structure, and unmistakable grape-and-berry aromatic profile that built the strain's decades-long reputation.
Effects
Granddaddy Purple delivers a heavy, fast-acting indica experience anchored by deep full-body relaxation and warm cerebral euphoria. Best reserved for evening use, post-dinner wind-down, or any moment where serious decompression is the goal. A classic, beloved nighttime cultivar that fans return to for a reason.
Flavor & Aroma
On the palate: ripe grape up front, with sweet berry through the middle and a warm earthy-sugar finish on the exhale. Smoke is smooth and unmistakably fruit-rich. The terpene profile reads grape-and-berry with myrcene depth — see the COA for the exact terpene breakdown of the current batch.
