5. Operating Instructions
The Wisecoco Greenhouse Vent Opener allows for manual adjustment of your greenhouse roof vent to control airflow and temperature.
To Open the Vent:
- Gently push the greenhouse vent upwards from the inside.
- As the vent opens, the opener bar will extend.

To Close the Vent:
- Remove the pin from the opener bar.
- Gently pull the vent downwards until it is fully closed.

The design allows for precise control, enabling you to vary the opening almost inch-by-inch to maintain a consistent temperature range within your greenhouse.
