Looking for a no-fuss, passive, way to keep your DIY greenhouse ventilated? Or maybe you have a shed or other building that needs passive air cooling and ventilation. The Thermatic Vent automatically opens and closes based on temperature, helping maintain the ideal airflow without needing electricity or batteries. It’s an easy, hands-off solution for providing passive climate control and keeping plants comfortable. Best when used in multiples with high-mounted vents to allow hot air to escape and low-mounted vents to allow cool fresh air to enter. Show more
