GDP Genetics (Ken Estes) cannabis strains

GDP Genetics, founded by Ken Estes, is synonymous with Granddaddy Purple (GDP), one of the most recognisable indica strains in cannabis history. Estes developed GDP in California in the early 2000s by crossing Purple Urkle with Big Bud, creating a deeply purple, grape-flavoured indica that became a benchmark for purple cannabis varieties worldwide.
