Ken Estes

Ken Estes is a foundational and legendary figure in the modern cannabis industry, best known as the creator of the world-famous **Granddaddy Purple (GDP)** strain. A Northern California native, Estes began his journey in the 1990s, initially cultivating for medical patients. His breakthrough came in 2003 when he successfully crossed the indica-dominant **Purple Urkle** with the potent sativa **Big Bud**. The result was Granddaddy Purple, a strain that revolutionized the market with its stunning deep purple coloration, sweet grape and berry aroma, and powerfully relaxing, full-body effects. GDP is credited with popularizing purple cannabis phenotypes globally and became a cornerstone of the 'purple' craze in the 2000s. Beyond GDP, his seed bank and brand have developed other notable strains like **Purple Diesel** and **Ken's GDP**. Estes's philosophy centered on breeding for consistent, high-quality medicinal effects and unique aesthetic appeal. His work helped bridge the medical and recreational markets, making top-shelf genetics accessible. Although less active in direct breeding today, his legacy is permanently etched into cannabis history through GDP, which remains one of the most recognized and sought-after strains worldwide.
