Carbon monoxide harmful to plants?

[DavidCampen]

I use one of these Coleman catalytic propane heaters inside my orchid room.

I have it connected via piping to 20 lb propane tanks outside. I have slept in a large tent with 2 of these burning during the night and I still woke up the next morning.

Here is a non-vented, catalytic propane heater intended for RVs, it puts out more heat than the Coleman catalytic heaters.

"I was told once by my biochem prof that if we ever suspected CO poisoning we shouldn't move."

That's what the Port Authority initially told people to do when the planes flew into the buildings on 911!
When in doubt, get out!

Good reasoning, Eric.
