Prevent Costly Flood & Drain Blockages
In active hydroponic systems like IWS Flood & Drain, aggressive root systems naturally reach downward toward water sources. Without a barrier, roots can quickly expand through pot drainage holes, clogging brain pots, return lines, and valves.
The IWS 320mm Copper Disc solves this problem naturally. The specialized copper coating acts as a gentle, biological air-pruning barrier. When root tips touch the copper surface, their growth naturally halts at the disc surface rather than continuing into drainage lines. This keeps your system running smoothly and prevents standing water or flood hazards in your grow room.
Key Benefits for Growers
-
Root Pruning Technology: Naturally stops downward root migration, encouraging lateral root branching for a thicker, healthier root mass inside the pot.
-
System Protection: Prevents root ingress into 16mm/25mm pipework, brain pots, and return valves to maintain uninterrupted nutrient flow and drainage.
-
Antimicrobial Properties: The copper-treated barrier provides additional resistance against stagnant water rot and root pathogens at the pot floor.
-
Simple, Reusable Installation: Easy to clean and reuse across multiple growing cycles.

Frequently Asked Questions
Which side of the IWS copper disc faces up? Always place the disc with the copper-coated side facing UP into the pot. The roots need to make contact with the copper layer as they grow down through the substrate.
Will the copper harm my plants or nutrients? No. The copper layer acts strictly as a contact barrier at the root tip level. It does not leach toxic amounts of copper into your nutrient reservoir or harm overall plant health.
Can I reuse IWS copper discs between grows? Yes. Between crop cycles, simply soak and wash the disc with mild cleaning agents or peroxide, rinse thoroughly with fresh water, and allow to dry before reinstalling.
