Features | The automatic vent opening device automatically controls the temperature in the greenhouse. As the air inside the greenhouse warms, the vents are gradually opened to allow the correct amount of air to flow into the greenhouse, and closed when the optimal temperature is reached. The ventilating arm is designed with natural wax, which expands to push the piston, thereby raising the window, because the air warms up, then shrinks when it cools, and is closed with a spring. The automatic vent opener can operate without electricity. |
