Catalyst Heaters for cheap CO2 in small grow rooms?

[Zandor]

got a new meter but it still needs to be cal'd.. it came out of the box reading outside air at 1000ppm.. i cal'd it at 400ppm outside then brought it in for some fun..

i tried dry ice first and it brought the room up nice.. then the burner.. which was nowhere close to a lb of dry ice sublimating under an hps light but it did work.. will be more specific when i get this meter actually calibrated with some real cal gas.

Right on...it sounds like you are having fun now.

Keep up the good work :thumbsup:

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
