CO2Gro is the quick, easy, highly effective way to get growth- and yield-enhancing Carbon Dioxide (CO2) into your growing space. This ‘home-brew’ setup produces high purity CO2 from two materials. You buy these A & B materials separately and combine in this Vessel. Once the Vessel is fully assembled and the mixture is brewed you can deploy the Carbon Dioxide on-demand with brilliant levels of adjustability.

Why add CO2?

You bring light inside to support photosynthesis, why not CO2? The easy answer to this is that Carbon Dioxide is already present in your growing space. But fruiting and flowering plants can happily use more than your natural levels of CO2, much more.

Indoor CO2 levels will vary depending on your existing setup, but they generally fluctuate at around the 400ppm mark. Fruiting and flowering plants will thrive in levels of up to 1200ppm.

When plants get more CO2, they can capture and convert light energy into chemical energy at an increased rate. This helps to stimulate enhanced development and can bring forth denser, richer, more potent yields.

Why use CO2Gro?

The on-demand adjustability of CO2Gro makes it an excellent option when considering a CO2 input. Because the unit is power-driven you can regulate output using a controller and set to activate or deactivate as required. Combine the CO2Gro with your lighting controls and you can ensure nothing is wasted during lights-off. For sure, 1200ppm of CO2 is great, but anything beyond that is essentially useless. So having the CO2Gro’s switchable functionality really helps you to keep costs down.

CO2Gro Build Quality

The CO2Gro Vessel itself and associated hardware are produced to a high standard. Such reassuring solidity helps no end when setting up and allows for extensive reuse. Everything you need to know to get going is marked out on the Vessel itself in simple steps and the controls are instinctive to master.
