How can the lighting be increased? Using lamps would work? How water vapour level is increased? Pls tell

[@goose1223]

Yes please tell

[@goose1223]

Also lamps would work

[@sanaraheelahmed3607]

Hey! Yes, using lamps and other methods of artificial lighting would increase the lighting. As for the water vapor levels - when you burn a fuel (combustion) it produces carbon dioxide and water. As this reaction is taking place in a heater in this situation, and because greenhouses are very warm, the water produced will be in the form of water vapour (gaseous state) as the temperature is greater than its boiling point (above 100 degrees C).
