All results shown were observed and documented in demonstrations of CO2 Delivery Solutions. Results may vary according to crop and growing conditions. CO2 Delivery Solutions is not intended for use as a pesticide or herbicide.

CO2 Delivery Solutions is sold as a novel method for delivery of CO2 to plants.

Indoor use of CO2 gassing has enhanced plant yields for decades. However, over half of the CO2 gas is typically lost through leaks in indoor operations, and the vast majority of greenhouses cannot use CO2 since they require ventilation through which nearly all the CO2 in the air escapes. Of course outdoor growers cannot gas CO2 at all.


Indoor CO2 gassing levels of 800-1500 ppm are also not ideal for worker health and safety. CO2 GRO's patented CO2 Delivery Solutions enables growers both indoor and outdoor to consistently deliver optimal amounts of CO2 to their plants via an aqueous CO2 solution, resulting in higher yields, shorter grow cycle times, safely and profitably.

Innovative Technology
  • Apply CO2 to your plants SAFELY.

  • Applied to the plant by FINE MISTING.



  • INDOOR and OUTDOOR use.

  • CUSTOM ENGINEERED for your facility.




CO2 Delivery Solutions can be integrated into existing boom irrigation, overhead misting systems and if you don't have any existing irrigation, 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 CO2 Dissolution Control System, which comes on a skid or can be integrated into booms. The CO2 completely dissolves in the water creating a saturated aqueous CO2 solution.


The CO2 solution is targeted directly on to the plant's leaves by misting micro droplets to create an aqueous film around the entire leaf surface. This film isolates the leaf 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.

Aqueous CO2 Misting vs CO2 Gassing

Aqueous CO2 is absorbed through the entire leaf's surface.
