Carbon dioxide is an essential gas necessary for plants. It helps them with photosynthesis which where plants convert carbon dioxide (CO2) coupled with light to feed themselves.

Does CO2 increase yield in plants?

You can increase yield and reduce time to harvest if you increase their CO2 intake alongside ample grow lighting. Increasing your plants CO2 intake along with lighting, causes the plants to produce increased sugar and oxygen. This increased sugar helps increase your crop yields

Keep in mind that this process only works in conjunction with good lighting. Florescent grow lights are great for propagation but not recommended by us for this purpose. We recommend MH and HPS grow lights or better yet LED grow lights to achieve maximum yields.

How much CO2 do plant need?

Generally, the level of CO2 in our atmosphere is 400 ppm but increasing this to 1000-1200 ppm can help supercharge your plants growth. If CO2 level increases beyond 1000-1200 ppm, it can be very harmful for your plants. This makes CO2 controllers or better yet multi-function controllers an important accessory to ensure your plants grow healthy and strong.

How to add CO2 into your grow room?

You can find CO2 tank and regulator kits and CO2 burners at to introduce CO2 into your grow room. CO2 burners produce the gas by burning propane or natural gas while tanks and regulator kits have CO2 tanks that release CO2 into the atmosphere. You can also use natural CO2 packs that can be hung from the ceiling of your grow tent or grow room to provide more CO2 to your plants without utilizing heat or electricity.

How to use CO2 in a grow room?

You can use multi-function grow room controllers to make sure that your photoperiod is synced with increased CO2 levels inside your grow tent / room. Given CO2 improves your plant’s ability to absorb light, you do not want extra CO2 in your grow room during the lights off period.

Check out our Learning Center for a host of information on managing the environment in your grow tent or grow room. We also have a complete guide on How to use CO2 to increase your yield.
