Greenhouses can be designed with roof vents, side vents, or louvers that can be manually or automatically opened and closed. Greenhouse ventilation relies on the buoyancy effect of warm air rising and escaping through roof vents while drawing in cooler air through side vents or louvers. This system is particularly effective in regions with mild climates. In larger or more controlled environments, mechanical ventilation systems are used. These systems may include exhaust fans and intake fans, often operated by temperature and humidity sensors. They help remove hot air and moisture while bringing in fresh air.
