Grand Daddy Genetics

Grand Daddy Genetics was founded by Ken Estes, a long-standing medical marijuana advocate with over 40 years of experience in cannabis cultivation. The company quickly earned international recognition for its dedication to crafting high-quality, stable genetics with standout flavours and effects. Their most iconic creation, Granddaddy Purple (GDP), helped define modern indica hybrids. With its signature grape and berry aroma, deep purple hues, and relaxing body high, GDP became one of the most awarded and widely celebrated strains for both medical and recreational use. Beyond GDP, Grand Daddy Genetics has expanded its catalogue with a variety of carefully selected and bred strains—each designed to deliver potent, consistent results. Their legacy is rooted in California, but their influence spans the globe. Overgrow is proud to offer South African growers access to these time-tested genetics from one of the most respected names in the cannabis breeding world.
