CO2 Delivery Solutions™

Watch this whiteboard video

Atmospheric enrichment of CO2 by gassing in protected horticulture operations has enhanced plant yields for decades. However, over half of the CO2 gas is typically lost through leaks even in sealed structures. About 85% of the world's 50 billion square feet of protected grows are unsealed and have open venting designs which makes atmospheric enrichment of CO2 uneconomical and impractical since nearly all of the CO2 gas would escape.

This means the vast majority of protected growers are not able to take advantage of CO2 enrichment which is proven to result in up to 30% more yield as plants are able to enhance photosynthesis. CO2 GRO's patented CO2 Delivery Solutions™ enables ALL protected grows to consistently deliver optimal amounts of CO2 to their plants via an aqueous CO2 solution, resulting in higher yields, faster growth, safely and profitably.

Innovative Technology
  • Apply CO2 to your plants SAFELY.

  • Applied to the plant by FINE MISTING.




  • CUSTOM ENGINEERED for your facility.




CO2 Delivery Solutions™ can be integrated into existing boom or overhead misting systems and if you don't have any existing misting system, no problem, we will design and implement one custom for your facility.

How CO2 Delivery Solutions   Work


CO2 from a gas tank and water from the facility source are plugged into the Aqueous CO2 Infusion System, which comes as an in-situ system or can be integrated into booms. The CO2 completely dissolves in the water creating a saturated aqueous CO2 solution.

The aqueous CO2 solution is targeted directly on to the plant's leaves by misting micro droplets that create an aqueous CO2 film on leaf's surface. This film isolates the leaf surface from the atmosphere and creates a diffusion gradient that favors the transport of CO2 into the leaf and other gasses out of the leaf.


The carbon is used by the plant for photosynthesis to grow and the oxygen is given off to the atmosphere.

More carbon is now available for the roots and shoots to grow, increasing yield and profits.

The 'Magic' is in the Misting

Aqueous CO2 is absorbed through the leaf's surface.

This means aqueous CO2 can be misted from overhead vs under the leaf.

Exciting Results

It is difficult to maintain 1200 ppm CO2 gas even in a sealed commercial facility throughout the grow cycle due to periodic venting.


Aqueous CO2 misting is effective year-round, regardless of venting periods.

Perimeter Protection™
  • Despite conventional wisdom, misting plants with aqueous CO2 also provides the plant with “Perimeter Protection™” to slow the spread of micro pathogens.

  • The fluctuation in pH on the plant surface when aqueous CO2 mist is applied slows the spread of micro pathogens. CO2 gassing alone does not provide this protection.

  • Reduce the spread of micro pathogens such as powdery mildew and E. coli by 99%.
