Furnace closet Co2

Not long ago I made a post about venting - I decided to drill a hole from my grow room into my furnace/hotwater heater closet.

It's working wonders but I'm wondering if I'm missing an opportunity to use Co2 from my furnace. Perhaps having the fan draw air from the closet INTO the grow room, of course it would also pull in fresh air from outside as well. Any thoughts?

You've penetrated the furnace exhaust shute to get co2 to your grow? That sounds completely stupid. Maybe I'm not understanding....

I have already thought about it. It’s not safe to do if you live or be in the house. I dream of having a greenhouse outside that I vent the furnace heat and cO2 and also the clothes dryer. But into the house is too danger.
 
My apartment has a closet that houses the heater and furnace. I exhaust into it since it has an exhaust that leads to the outside. I was wondering if I could instead pull air from the closet which should have CO2 and if someone else has done it.

If your furnace is dumping c02 into you home something wrong with it, If furnace is ok there should be no more c02 in the closet than in the room.
