Full length ridge ventilation. Wide span ventilation is a common method where flaps or windows are placed along the side walls of the greenhouse. These can be controlled manually or automatically to allow for effective ventilation. 

The advantage of wide-span ventilation is its ability to ensure even air circulation throughout the greenhouse. This is especially important to minimize temperature differences and create a consistent climate for the plants.
