These Root Control Discs or RCD™s are designed to fit the pots and tubs of Autopot systems. The film is made of a black cloth with a thin copper coating. It should be placed on the tray or saucer below the pot, copper side up. Its function is to prevent roots from coming out of the pot and invading the Aquavalve system. Its metal coating makes it very effective.
The film is available in 3 sizes. It is delivered individually or in packages of 10 pieces.
