External view of roof vent

The 6'x6', 6'x8' and 6'x10' greenhouses include a free roof vent for improved airflow. The picture shows the adjustable handle which is supplied as standard. Automatic openers which react to heat are also available - this popular option ensures effortless ventilation. A low level louvred vent also helps to improve the air circulation. It is not possible to fit a roof vent in the smaller 6'x4' greenhouse so a louvred vent is recommended if you need extra ventilation.
