The Automatic Vent Opener was designed to automatically control the temperature and humidity levels. It provides additional ventilation for all Palram Greenhouses, making gardening easier. As the air inside the greenhouse warms, the vent gradually opens to allow the correct amount of airflow into the greenhouse until the optimal temperature is reached.
- Opens vent at warm temperatures and closes when temperatures cool.
Features and benefits
The window vent automatically opens when the temperature reaches 12-15°C, circulating the air for a cooling effect. The mechanical system closes the vent when the temperature cools, meaning no electricity is needed.
- Growing your own produce helps to reduce the environmental impact of food
