Just make sure when you go in there, you may be breathing it to. Jim Roberts from Eclipse notes, Sometimes the cost looks staggering, but remember that most furnaces have a very active running schedule, so the paybacks, even at low gas costs, can be very fast. In fact, 1 ppm (part per million) of ethylene or carbon monoxide can cause serious damage. The company also provides assistance to customers looking to add recuperation to an existing burner system. In any event, the use of unvented space heaters is too risky for the commercial greenhouse grower. Lastly, research your plants temperature and humidity needs. This can be reduced by faster cycle times or the use of multiple vessels at various stages of cooling. They often can handle temperature changes and dry air better than smaller plants with thin leaves. One of the problems is that carbon dioxide is most effective when light levels are the highest during the day and the carbon dioxide is mainly produced at night when the heater operates the most.

Make the panel a decorative part of your garden design and folks wont even know you have a vent there. If you have a flowery plant and notice that theflower buds are falling from the plant or if their leaves are wilting, this may be due to low humidity. The exhaust system typically uses metal venting, often routed into a chimney stack, to exhaust the combustion gases created in the furnace fire chamber. Thats why the exhaust that leaves the system might be merely warm. A disadvantage is that the heat content of the incoming air has some variation, making precise combustion control more difficult. Normally furnaces and boilers are operated with about 50% excess air. Is Your Heater Hurting Your Plants Remember, ethylene is an odorless, colorless gas that is a harmful pollutant to your greenhouse crops. Im just wondering if i could use this free warm exhaust air and hopefully heat my small greenhouse with it. This colorless and odorless gas is harmless when breathed in small amounts (thats what we do all the time), but in enclosed spaces, a high concentration of CO can become extremely dangerous.

Cold air blowing directly on plants often strips it of its moisture. Russ Chapman from Firebridge notes that larger companies are starting to benchmark their large plants against each other, and against the competition, in terms of sustainability of the plants. The installer is going to put the PVC pipes about two feet away from a cherry bush, actually midway between the bush and the A/C compressor.
