All around airflow.

The AirDome is the perfect accessory to gardeners of all abilities. It has been designed to increase the amount of air around the root zone in plant pots.
If you are lucky enough to have power in your greenhouse or polytunnel this little addition can increase yields by up to 130%. It is very simple to use once assembled, which will take less than 30 seconds. The AirDome is placed at the bottom of the pot, covered with compost and then connected to an air pump. Oxygen is then supplied directly to the plants’ root zone, improving crop development and ensuring maximum growth.
