Description

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. There is no wrong way to put them in the pot as either side up works. Also, 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.

Pro Tip: To initially increase the permeability of your Root Control Square, you can soak them in a solution with a standard wetting agent diluted at the recommended rate for 48 hours and then put it in your pot. Do not rinse it off before using it after soaking in a wetting agent.
