Has anyone used there furnace exhaust to heat there green house or room?

So what is the impact of carbon monoxide on a plant? Kill it? Make it poison to smoke? Nothing? Help it?

Just curious.

i still have no idea but I'm a little nervous now to try anything with my furnace exhaust. I think i will just add my small heater to my greenhouse

there is NOTHING you need from your furnace, unless it is to heat your room/house.

well I am trying to heat my small greenhouse. I was hoping to find a free way but it looks like i will be using a small electric heater for the next month

I did a little research and it sounds like it wouldn't hurt your plants at all, just you. So if you can just get on of those hazmat suits with an oxygen tank for tending your greenhouse, you'll be fine.

Just kidding, stay safe, we like you!

Use the exhaust in a radiator kind of idea where none of the harmful gases exhaust inside the tent but the radiant heat from the rad is transferred to the inside tent air

CO2


CO

Like Technical was getting at, While you couldn't vent it directly, perhaps you could use it in another way... I dont know the distance it would have to go, but maybe wrap a long vent tube around your exhaust pipes to heat up the air inside the vent pipe. or perhaps wrap some aluminum dryer vent piping around your furnace and run it to your grow... get creative, but yea dont vent that CO directly anywhere.
