What gases are released from green a house?
That would depend upon whether the greenhouse is in use, and whether it is being heated, and how. Greenhouses heated with propane will release CO2. Greenhouses not in use may emit various gases, depending upon the state of decomposition of any organic material contained within them. In general, an unheated (or solar heated) greenhouse in use will tend to emit oxygen, via photosynthesis activity of the plants contained within it.
