Autopot Replacement Root Control 1Pot XL Disc Round - Black & Gold

Round Root Control Discs for round 25 L plastic pots as used in 1Pot XL, Auto9 XL, and Auto 3XL modules. Place one Root Control Disc into the bottom of each pot before adding substrates or plants. In 25 L pots we recommend that the Root Control Discs are used gold face down, although if desired they may be used gold face up. Root Control Discs help to prevent roots from leaving the pot and heading towards the AQUAvalve. They are highly effective due to their special metallic gold coating.
