93 Hoppy Trees


A collaborative sustainability project between Denver Beer Co, Earthly Labs, the Colorado Department of Public Health & Environment and The Clinic.

The pilot program aimed to capture waste carbon dioxide (CO2) at Denver Beer Co during the fermentation process, sell and deliver it to The Clinic’s cannabis grow operations, and use the CO2 to stimulate cannabis plant growth. The pilot revealed the ability for Denver Beer Co to keep the equivalent of 93 trees worth of CO2 from the atmosphere, while providing The Clinics’ CO2 needs for a complete 16 week harvest at a 15% reduced cost to commercial CO2.

The cannabis plants met their key growth milestones at the different phases of growth from propagation to vegetation, and flowering, and emerged healthy demonstrating expected weight and yield as compared to commercial CO2 sources.

You can find our 100% recycled Co2 grown flower products on shelves starting July 3rd, 2020 across all stores. We will have a variety of strains available, order online for faster service!

Time Lapse in the Grow

We set up a GoPro camera around our facility in order to track the progress of our plants grown with Denver Beer Co.’s recycled CO2. You will notice the video jumps around, this is because of the many different growing phases of cannabis. We start in the vegetation room and end in our main grow room, where the plants are harvested.

Look for the Seal
