A greenhouse can become too hot for you and your plants very quickly without a properly sized ventilation system to provide adequate cooling. An exhaust fan system or automated roof vents can provide all of the needed ventilation / cooling during cooler seasons, but cooling in the summer can be much more difficult. A combination of shade, proper ventilation, and an evaporative cooling system like a misting system or evaporative cooler is recommended when outside temperatures begin to heat up.
