Prevents Excess Root Growth
Place the AutoPot Root Control Copper Coated Disc inside the AutoPot 25L Pot gold face down prior to your soil or compost to aid in root control at the base of the pot. It keeps the roots from escaping out through the bottom of the plant and helps to maintain the operation of the AQUAvalve, keeping it free from debris and roots.
The copper coating repels roots so makes these discs highly effective as roots are tough and can sometimes grow through concrete, it is advisable to check for growth periodically. Simply trim any excess root growth with scissors and replace the discs between each crop.
