by taking the base genetics of Grandaddy Purple and recrossing them to recreate the strain from scratch. Contrary to what is written above it's genetics are Dutch passion Lavender #1 and Original Big Bud (which despite it's shwaggy reputation, is actually very potent when it is not overbread.) Both were grown from Amsterdam seed stock and crossed to recreate fresh genetics. The difference between the standard grandaddy and the much more stinky and resinous Ken's is that the Ken's is only a few generations from the original mother stock. Where as the clones floating around the club can be hundreds or even thousands of generations down the road. It is also called "OG GRANDADDY" because it is the strain in it's original glory. It is not a cross of OG KUSH AND GRANDADDY PURPLE as people will try to tell you. The strain was kept under wraps by a small inner circle of medicinal growers for many years, but has begun to surface as clones in several clubs in the Northern California, Bay Area
