Proper ventilation is crucial in a greenhouse to maintain healthy plants. Adding an Alton Louver Window improves airflow, creating an optimal environment for plant growth. Alton Louvre Vents fit neatly into the side panes of your Octagonal greenhouse, providing essential extra ventilation for healthier plants and better produce.

The standard Alton Louver Window includes a manual handle for easy operation, while an optional automatic louver opener is available for hands-free temperature-sensitive vent adjustment.

Note: this item is only available to order with the purchase of an Alton Greenhouse.
