How to increase the carbon dioxide concentration for cannabis?
How to use CO2 in cannabis grows is one of the many questions that we're frequently asked. CO2 is essential for cannabis plants and every other plant, as to them CO2 is like oxygen and they need it to survive. Cannabis plants can deal with CO2 levels of up to 600% the amount that there naturally is in the air around us. Basically, it makes their cells multiply much faster, so if you use extra CO2 during the flowering period you'll get buds that are much thicker than usual which, if done correctly, makes for a much bigger yield. If you don't use CO2 in the right way you could end up with yellowing plants, or long stretched out plants with hardly any buds. You're going to need to know what you're doing to implement CO2 correctly. There are many systems that can be used to get more CO2 into your crop; beginner systems that are used as a little extra boost and don't require much care, and then professional systems that measure the PPM of CO2 that there is in the atm...
