Keep it. It seems a very nice setup. I live in a hot country (Spain), so i must avoid heaters, but i think it can be a good option for northern growers.
knna Reviewed by knna on . Catalyst Heaters for cheap CO2 in small grow rooms? I am an engineering student at a top 10 engineering school and I am not involved in any illegal activities. I do like to tinker and I am currently growing vegetables hydroponically and looking for a CO2 solution. I have a catalytic camp heater from Coleman camping gear that I got at wally-world for $30 (sportcat model) and I am interested in determining the feasibility of using it to generate CO2 for my veggies. It is a heater that produces mostly CO2 and H20. I post my comments here as Rating: 5
