In my house I have a gas forced air furnace that is vented from my basement to my roof, so it does not kill me off as I sleep. Now, what I am wondering is if I were to tap into that vent line in the attic on its way to the roof vent could I blow that "wasted CO2" into my grow room in the winter and not kill myself ?

I know that some CO2 generators use natural gas to make CO2, so I am curious if I have a free source of it and not realizing it. As far as cost, I may need to spend 300-400 bucks at the very most. All I would need is a "T", another length of flexible duct, and probably 2 inline fans. One to suck it from the vent line, and one to keep it moving into grow space. Could hook a probe from grow room to CO2 monitor thingie with both fans hooked to it and only have them suck if level drops below 1500 ppm. If furnace isnt on, it gets cool air, if it is, it gets CO2. I like this idea.

In the summer I would use the bottled CO2 of course, but I could probably get 6-7 months worth free if y'all think the concetration would be enuf in the emission from the furnace.

Maybe many of us are sittin on a source of CO2 that we didnt even know about.

Any thots or ideas are appreciated.
