Ken Estes is a cultivator and celebrated breeder. He is best known for developing the Granddaddy Purple strain, but he also has a number of clinics throughout the State of California. Ken was turned on to the therapeutic benefits of medical cannabis after being paralyzed from the waist down in a motorcycle accident.
Later, he encountered a woman who was treating patients with medicated brownies and decided to follow a similar life path. Estes became an activist for medical marijuana, working with Dennis Peron at one point in time. Now, he is best known for his work with the Granddaddy Purp Collective in Richmond.
