Auto Pot Roots Control Square

1x Root Control Square for 2.2 / 3.9 gal Pot designed for growers using 1Pot, easy2grow modules or systems and Auto8 tray systems, the Root Control Square prevents roots from encroaching on the AQUAvalve. We recommend the Root Control Square is used gold face up though growers may still use the Root Control Square effectively gold face down if they wish.
