The IWS Copper Disc is a 250mm round copper disc specifically for use with the IWS Flood & Drain hydroponics system. It is designed to prevent roots and potting mixes from leaving the plant pot. To use simply place the copper disc in the bottom of the pot before you add your potting mix. Then check occasionally for any roots trying to escape from the bottom.
