Autopot - Square Replacement Root Control Disc

£1.10

The AutoPot Root Control Discs fit the Autopot and Easy2Grow systems. The black and copper discs prevent roots and substrate from leaving the base of the pot and making contact with the AQUAValve.  Copper side should face up.  

These discs can be reused but for best results replace after each grow cycle to prevent any contamination.
