Water Heater Room-CO2

"When a stove or water heater bums gas it produces water vapor and CO2" -http://cannabisguide.com/closet_culture/Chapter_16.htm

This makes me ponder, if I setup a 250w HPS in my water heater room outside... Too bad it is summer time here in the Southwest and temps are already hitting 80+. Soon they will hit 95+, but in the winter, this would be perfect. My water heater is in a little closet type thing with a door and such, and it is right outside my bedroom/1ft of wall from my shower.

Just a little idea for those who are looking for a way of producing CO2.

Well, I will read that link you supplied, but there is a little hick-up with this idea.

If your using gas burning appliances (Boiler, Furnace, Water Heater), they will be vented to the outside, and for good reason. If you circumvent the vent, you might be helping your plants, but you will be killing yourself.

While this might be a good idea for those who have mechanical rooms outside of their residence, and plan on doing something like you've described, for the other 95% with the mechanical rooms inside, I would highly recommend you do not try it. :)

or composts generate co2

yeah i though it creates CO aswell.

It is outside but still connected to our house. Like a door from the outside except when you open it, there is a small room with a water heater in it and about a 4x3x7 space. There are venting slots in the door (2 vent things).
