Straight or Curved Rack for Ventilation Galvanized Steel Pipes Maintaining the ideal conditions inside a greenhouse wouldn't be possible without effective ventilation. Roll Up Curtain Greenhouse One way this can be achieved is by the controlled opening and closing of air vents. This allows the flow of heat, moisture and CO2 in the greenhouse to be manipulated. Various ventilation systems are possible depending on the type of greenhouse. A greenhouse can be ventilated through ridge vents and sidewall vents, either operated manually or controlled by a climate computer.Greenhouse Film Electric Roll Up
