In fact, 1 ppm (part per million) of ethylene or carbon monoxide can cause serious damage. One of the byproducts of combustion is carbon dioxide which can enhance plant growth. As the heater operates, oxygen is used and combustion efficiency decreases unless makeup air is available. For example, you canbuild a terrariumthat allows you to still view and enjoy the plants but helps keep out colder temps and dry air. However, he also points out that for operators with site emission permits written on a lb/MMBtu basis, recuperation allows the use of more furnace capacity, hence increased productivity. We can help.

Increased moisture levels can cause increased incidence of disease problems including fungi, blight and molds. Never allow gases to remain inside the greenhouse. A disadvantage is that the heat content of the incoming air has some variation, making precise combustion control more difficult. Does my high efficiency furnace need two sources of outside air.
