Growing With CO2 Supplementation.

Plants use CO2 as part of the process of photosynthesis; using light, CO2 and water to create energy for the plant. Ambient CO2 levels are usually 300-400ppm. As light intensity increases more CO2 can be utilised by the plant which will in turn allow the plant to use more of the available light and turn it into energy.

We recommend increasing CO2 levels to between 600-1200ppm, this can be achieved in several different ways.  

For smaller spaces, natural-release CO2 bags are an effective way to increase and maintain levels in your growing area. We recommend the ExHale XL Bag from Homegrown CO2 to gently and naturally increase your CO2 levels.  

For complete control over your environment, we recommend a dedicated CO2 controller that will maintain set levels using bottled CO2 or a gas burner. 

When using CO2 bottles with a doser, using a fan-speed controller to reduce the speed of your extraction fan when dosing ensures your plants use the available CO2 while it is in the room.  

Please Note - To utilise the higher PPM of CO2 in the environment, the stomata in the leaves of the plant must be fully dilated (open). This is achieved by raising the temperature of the growing area to a minimum of 28°C or, ideally, as high as 32°C (using CO2) during ‘lights on’.
