this growop gen-2 2 burner co2 generator is in like new condition. I briefly ran it in my room but I could not keep my room temperature low enough when using the co2. I determined that my room is too small for the unit with the heat it makes so I went with tank co2.
Wish it would have worked out cause you can make a lot more co2 with this and a tank of propane. It can be run 1 burner or 2.
