Adding carbon dioxide (CO2) to your indoor garden will make your plants healthier and more productive. All plants need a sufficient amount of CO2 to carry out the process of photosynthesis. During this process, the CO2 is combined with vital nutrients, sunlight, and water to create the sugars that give the plant energy.

Insufficient CO2 levels will drop your plant's ability to make power via photosynthesis. Plants can handle a lot more carbon dioxide than they generally get from their environment. Adding CO2 to your hydroponic growing environment is one of the easiest ways to promote production and increase your harvest.
