Carbon dioxide generator explained

A carbon dioxide generator or CO₂ generator is a machine used to enhance carbon dioxide levels in order to promote plant growth in greenhouses or other enclosed areas.^{[1] [2]} Carbon dioxide generators have been used to help grow marijuana.^{[3] [4]} They can be fueled with propane or natural gas. CO₂ generators were used mostly by commercial growers until smaller and less expensive systems made the technology more widely available to hobbyists.^[1] The generators also give off heat.^[5] Using compressed CO₂ is an alternative to generators.
