Common ventilation options
Side roll-up ventilation is economical for tunnel and film greenhouses. It helps remove hot air and gives growers simple manual or motorized control.
Roof vents improve natural airflow in multi-span and glass structures, especially when hot air needs to escape from the top of the greenhouse.
Exhaust fans and circulation fans can support airflow when natural ventilation is not enough or when crop density is high.
Insect netting protects crops but also reduces airflow. The structure and fan selection should account for this resistance.
What to send for ventilation planning
Send crop type, greenhouse size, local temperature range, humidity concern, insect pressure, and whether the greenhouse is used seasonally or year-round.
