Compatible with the 1Pot system, the easy2grow Kit, and the 2Pot extension trays, the Root Control Discs (RCDTMs) allow you to expand your growing space without disrupting your plants' roots.These discs, which are black and gold, should be placed on the pot's tray with the gold side facing up. The Root Control Disc is there to stop the roots from growing out of the container and into the AQUAvalve system.This is because they have a specific metallic gold covering that greatly increases their efficiency. Keep in mind that roots, no matter how delicate, can penetrate concrete, so it's a good idea to check on your plants every so often and see if any have gotten through. If this is the case, you can use scissors to remove the offending roots.The plant will not suffer any damage as a result of this. The discs are durable enough to endure for multiple seasons, but replacing them at the start of each new season is necessary to avoid the spread of any diseases that may be present.
