IWS Flood & Drain Pots, Stands and Outer Containers

The Core Pot Components Behind Every IWS Flood & Drain Room

These are the genuine IWS components that make a flood and drain system work: the pot stand that sets your flood height, the outer pot that holds the solution, and the inner pot that carries your substrate. The combination matters more than growers expect. Pair a free-draining inner with a fine medium and fragments wash into the pipework and block the system; get the stand height wrong and the flood never reaches the root zone properly, leaving weak roots and poor nutrient uptake despite a perfectly good feed.

Key Benefits

• Universal Pot Stand - raises containers so solution floods to exactly the right level, with a sloped drain surface and V-shaped gland indent. 320mm (d) x 85mm (h)
• Aqua Inner - effectively a net pot, best with free-draining, low-retention media such as clay pebbles. Holds 6.5 litres, 185mm (h) x 285mm (d)
• Culture Inner - sealed sides for finer substrates like coco coir, stopping fragments blocking the system. Holds 6.5 litres, 185mm (h) x 285mm (d)
• Punch Pot - straight sides make full use of the outer and suit any medium. Holds 10.5 litres, 185mm (h) x 285mm (d)
• IWS Outer Pot - drilled, sits on the stand and houses any inner, flooding the medium from underneath. 230mm (h) x 290mm (d)
• Strong, resistant plastic for long-lasting, high-performance service

How to Use

• Build order: pot stand first, then the outer pot, then your chosen inner inside it
• Gland clearance: line the V-shaped indent up with the IWS gland so the drain run is clear
• Match inner to medium: Aqua for pebbles, Culture for coco, Punch for maximum volume with any medium
• Fill: add substrate to the inner, settle it and plant - do not overfill above the rim
• Commission: run a cycle empty and confirm solution reaches the root zone and drains fully back
