Pohjola Garden automatic greenhouse window opener makes greenhouse ventilation effortless and worry-free. This mechanical opener operates completely without electricity or batteries by reacting directly to temperature changes. When the sun warms up the greenhouse, the cylinder expands and opens the window automatically, and as it cools down, it closes by itself.
The durable construction is designed to withstand varying weather conditions and is easy to install on most greenhouse models. With the adjustable opening temperature, you can create the best possible growing conditions for your plants without constant monitoring.
