About the
4 Plants Cup 

The 4 Plants Cup is a celebration of legally homegrown, responsibly cultivated cannabis by individual Canadians.

The 4 Plants Cup honours the cannabis plant, growers at all levels, and the community.

Registered participants will cultivate their legal cannabis plants and select their best 28 grams of one cultivar (strain). This submission will be shipped to a central location for screening and packaging into judge packs. Contestants will be required to mail in a self-addressed pre-paid envelope with their submission, which will enable them to receive back eight 3 gram samples to judge and score. All judging is done blind by participants, with details on review factors coming soon.
