Multi Span Sawtooth Greenhouse: Natural Ventilation Greenhouse for Hot & Humid Commercial Farming
Release time：
2026-10-29 16:26
A multi span sawtooth greenhouse is a top commercial greenhouse choice for hot and humid climates. Many growers pick it across Southeast Asia, the Middle East and other tropical regions. First, it differs from standard arch multi-span greenhouses. It has a staggered sawtooth roof with continuous top vents. This design uses the chimney effect for strong passive ventilation. As a result, it cuts cooling costs and maintains a stable growing microclimate inside.
How does it work? Hot, humid air rises. It escapes directly through the high vertical sawtooth ridge vents. At the same time, cool fresh air enters through side roll film vents. This setup creates steady cross airflow. It prevents overheating and excess moisture. It also lowers risks of fungal diseases, so you do not need to run exhaust fans nonstop.
We build the frame with hot-dip galvanized steel. This multi span sawtooth greenhouse joins multiple spans into one large growing space. Therefore, it boosts land usage and creates plenty of room for trolleys, fertigation systems and hydroponic racks. PO or anti-drip PE film serves as the standard covering material. Besides that, you can add shading, insect net, evaporative cooling and automatic vent drives as optional upgrades.
It suits many growing projects. You can grow leafy vegetables, tomatoes, peppers, cut flowers, seedlings, medicinal herbs and substrate hydroponics here. Furthermore, the sawtooth top vents perform better in rainy, high-temperature zones. They offer stronger rain protection than regular roof vents.
