  • Item #: 20402

The AirDome has been designed to increase the amount of air around the root zone in the pot. If you are lucky enough to have power in your greenhouse 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.

AirDome Contents List

  • 1 x AirDome body
  • 1 x 6mm (1/4 inch) cross connector
  • 4 x Pieces of blue bubble pipe
  • 1 x 0.5 mm (19.7 inch) length of clear air line
  • 1 x Full instructions

Need:  Air Pump


  1. Take the 1/4 inch cross connector and attach the 4 blue pieces of bubble pipe to it.
  2. Then connect all four ends of the blue bubble pipe to the four connectiion points inside the Air Dome
  3. Finally, connect the clear air pipe to the outside point of the AirDome.  Heat the pipe in hot water to soften the pipe and to allow for an easy connection to the AirDome.
  4. Simply place the AirDome at the base of your autopot and cover with the medium of choice.  It is advisable to use a "fluffy" mix, such as 50% soil with 50% Perlite.  This will provide plenty of air pockets within the mix, maximising the effectiveness of the AirDom.


  • Using heavy soils or peat will not enhance the effectiveness of the AirDome, as they will become wet, heavy and compressed.
  • The Airdome should only be switched on during the daylight periods.  Always ensure that warm air is blown in and around the root zone.  Temperatures between 18 and 22 degrees Centigrade (64 - 72 degrees Fahrenheit) are ideal.  Temperature below 5 degrees Centigrade (32 degrees Fahrenheit) and above 30 degrees Centigrade (86 degrees Fahrenheit) will potentially damage the roots.


  • Raise your air pump higher than the AirDome(s) to prevent water from siphoning back when the pump is off or use a non-return valve.
  • Use a timer to turn the pump on and off when the air temperature is warm and before it gets too cool.
  • Many AirDomes can be linked together using 6 mm (1/4 inch) connections, or for larger AirDome setups, use 16 mm (0.63 inch) pipe as the supply line, reducing the pipe at each AirDome point with the AutoPot 16 mm (0.63 inch) to 6 mm (1/4 inch) Cross Connector.
