IWS Outer Pot - 16 L

The IWS Outer Pot – 16 L is a durable, high-capacity container designed to house the IWS Inner Drilled Pot within professional flood-and-drain hydroponic systems. Engineered for strength and long-term reliability, this outer pot forms the foundation of the IWS modular pot system, holding nutrient solution during flood cycles and ensuring stable support for medium-to-large plants.

Constructed from tough injection-moulded plastic, the outer pot withstands constant exposure to moisture and nutrient solution without weakening or warping. Its smooth internal walls allow nutrient water to flow freely around the inner pot, ensuring even distribution during irrigation cycles. The 16-litre capacity provides generous root space, making it suitable for vigorous plant growth across soil, coco, clay pebbles, and hydroponic media.

Designed for seamless compatibility with all IWS Standard and PRO setups, the outer pot is essential for maintaining system performance, stability, and efficient nutrient circulation.
