Frequently asked questions
What does the IWS Root Disc do?
It is a copper-treated disc that encourages natural root pruning. It stops roots circling or growing into the drainage fittings, helping keep the root zone healthy and irrigation flowing freely.
Where do I put the IWS Root Disc?
Place it in the base of the pot in your IWS pot or Flood & Drain system, where it prunes roots before they reach the drainage fittings.
