A note from the founders

The Grow-Off, launched in 2016, has quickly become the largest science-based cultivation competition in the cannabis industry. We challenge licensed growers with identical genetics to see who can generate the most cannabinoids, highest terpenes and greatest yield from a single plant. In 2019 we’ll host competitions in Colorado, Northern California, Southern California, Oregon and Canada. We hope you’ll join us as we continue to reshape the cannabis industry through our data driven approach.
