Producing C02

There are many ways to raise the CO, content of an enclosed grow room. The two most popular ways are to disperse it from a tank or burn a fuel to manufacture it. Carbon dioxide i5 one of the byproducts of combustion. Growers can bum any fossil (carbon-based) fuel to produce CO, except for those containing sulfur dioxide and ethylene, which are harmful to plants. Carbon dioxide gas is a by-product of fermentation and organic decomposition. The CO, level near the ground of a rain forest covered with decaying organic matter could be two to three times as high as normal, but bringing a compost pile inside to cook down is not practical. Dry ice is made from frozen CO,. The CO, is released when dry ice comes in contact with the atmosphere. It can get expensive and be a lot of trouble to keep a large room constantly supplied with dry ice. It is difficult to calculate how much CO, is released into the air by fermentation, decomposition, or dry ice without purchasing expensive equipment.
