The Root Control Discs are designed to fit the 1Pot system, the easy2grow Kit & the 2Pot extension trays to extend the easy2grow Kit.
These discs are black & gold in color and are placed in the tray underneath the pot, gold face up.
The purpose of the Root Control Disc is to prevent roots from leaving the pot & heading towards the AQUAvalve.
They are very effective due to the special metallic gold coating.
