Pumping Boiler Exhaust into Greenhouse - Growing in Greenhouses - International Cannagraphic Magazine Forums

I'm wondering if it's possible to use natural gas exhaust to increase C02 in the greenhouse atmosphere. I have a combination heater/boiler (Combi), which has an exhaust that leaves the back of my house where my garden is. If I ran the exhaust into the greenhouse, it would supply heat and C02, but I'm thinking it may also contain other biproducts of natural gas combustion.

Has anybody tried this?

people have done it and died, only the really intelligent and brave/stupid have done it and survived!

Depends what has been added into the natural gas by the supplier.

Propane when burned breaks down into Co2 and water vapor. Whereas some of the municipal gas suppliers that supply whole towns etc, will add in other chemicals to help you detect leaks. This stuff will almost ALWAYS give you a byproduct that include CO. Plants will not use CO and it will remain in the air. Unless vented out on a regular basis it could become a problem for you as it'll just pool up and remain in there until you breath it in. Once CO is in your lungs it will attach itself to blood cells. You'll start feeling sick and dizzy. If you are continually exposed to large concentrations of CO you could kill yourself.

Sorry, I forgot to include that the green house I have is not a walk-in type. It's like a huge encased shelving unit that is accessed from the front.

I'm already aware of the presence of CO in natural gas combustion, and I would NEVER even think of doing such a thing in a walk-in style greenhouse because yes, it is a death wish. However, I know that CO is not really poisonous to plants because it oxidizes quite quickly, thus creating CO2.

To rephrase my question, I'm wondering if anyone has done it with a non walk-in greenhouses....if anyone is actually using those. I imagine it's possible if you maintain proper CO2 levels, and have efficient fresh air intake/outtake. However, what other biproducts could be present? The combi is running on a municipal system.
