The roll-up or fold-down ventilation system on the sides and fronts allows air to be renewed in the lower parts of the greenhouse, and opening them creates air currents inside the greenhouse. Its use is particularly recommended for low crops. An insect-proof net is permanently installed to protect crops from natural enemies such as flies and other insects, rodents, animals, etc. This net maintains the level of porosity necessary for greenhouse ventilation. This system can be electric or manual, depending on the customer's requirements.
