IWS Copper Disc (250 mm Punch)

The IWS Copper Disc (250 mm Punch) is a high-quality root control insert designed for use with larger IWS pot systems. Made from specially treated copper-infused fabric, this disc prevents root circling and unwanted root penetration by creating a natural air-prune effect as roots reach the pot edges. This promotes stronger, more fibrous root systems and supports healthier, more vigorous plant growth.

Designed to sit neatly at the base of 250 mm punched pots, the copper disc allows water to drain freely while inhibiting root escape into the lower chamber of the hydroponic system. This improves nutrient uptake, prevents system blockages, and reduces the risk of roots invading pipework or stand-up systems. Lightweight, durable, and long-lasting, the IWS Copper Disc is a simple yet highly effective upgrade for any IWS Flood & Drain or PRO hydroponic setup.
