Who has won the most Cannabis Cup awards for pot and hash? While Greenhouse (coffeeshop and seed company) leads the pack, over the last five years, Barney's (coffeeshop and seed company) has dominated. This is a rough estimate, but it shows the vast number of shops and seed companies that have won awards over the years. If you add De Dampkring and Kiwi together, their total is 31. Sensi and White Label are also affiliated for a total of 12.
