Stops roots tangling into your pipework before it becomes a problem. Simple, proven, works every time.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eIWS Copper Discs are a \u003cstrong\u003eroot control barrier\u003c\/strong\u003e designed specifically for IWS flood-and-drain systems. Placed copper-side up at the bottom of your inner pot, they prevent roots from growing downwards into the drainage pipework whilst encouraging lateral root development through natural air pruning. It's a straightforward fix to a real problem—blocked systems cost time and money.

Instead, they develop laterally within the pot, creating a stronger root mass that stays contained. No roots escaping into your pipes. No blockages.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSizing\u003c\/strong\u003e\u003cbr\u003eIWS Copper Discs come in three sizes to match your pot type. The 170mm disc fits Culture and Aqua pots. The 250mm disc fits the Punched Pot. The 320mm disc is cut for 25-litre Flood and Drain inner pots. Check your pot type before ordering—the fit needs to be correct.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReplacement cycle\u003c\/strong\u003e\u003cbr\u003eOver time, the copper coating wears.
