Abstract: A machine that produces Carbon Dioxide Gas for horticultural use is described. The machine produces CO2 gas by accurately controlling a chemical reaction between an acid and a base. The chemicals involved are Sodium Bicarbonate (Baking Soda) and Muriatic Acid (Hydrochloric swimming pool acid). The machine comprises a plastic container, a peristaltic pump, a submersible mixing pump and an output filter. The peristaltic pump draws acid and pushes the acid into the plastic container through acid resistant tubing. The acid exits the tubing directly into the flow of water mixed with Sodium Bicarbonate created by a submersible mixing pump mounted inside the plastic container. The acid/base mixture combines to produce CO2 gas and salt water. The gas builds inside the plastic container and then exits via another tube. This tube terminates with an acid filter, which scrubs away any stray acid fumes allowing only clean CO2 gas to exit.
