Tray2Grow Root Control Sheet

1x Rectangular Root Control Sheet suitable for use with Tray2Grow. During setup, pre-soak your Root Control Sheet and lay it, copper face up, on top of the capillary matting supplied with your Tray2Grow. Root Control Sheets help to prevent roots from penetrating the capillary matting and heading towards the AQUAvalve. They are highly effective due to their special copper coating. You can get a couple grow cycles out of the root control material. If the copper coating oxidizes off, you can still reuse them as there is copper woven throughout the material as well.
