IWS Flood & Drain Remote System

IWS Flood & Drain Remote System

The IWS Flood & Drain Remote System gives growers full control over nutrient delivery, root development, and feeding cycles. You can choose between the Standard Remote and Pro Remote versions, and you can scale the modular layout to fit almost any grow space—from 6 to 48 pots.

For more than a decade, professional growers have relied on the IWS Flood & Drain range for its simplicity, reliability, and consistently strong plant performance. The remote timer lets you dial in flood durations down to the minute, and you can position it outside the grow room for easier access and cooler running temperatures.

Each kit includes a custom IWS FlexiTank, IWS Control Unit, pots, stands, pipework and fittings — everything needed for a fully automated flood & drain setup.

How does it work?

The system sends nutrient solution from the FlexiTank into the Control Unit at the times you set on the remote minute timer. As the Control Unit fills, it feeds every pot through the pipework. Once the upper float valve rises, it stops the incoming flow and locks in a consistent flood level. This cycle ensures even feeding, prevents overfilling, and creates the ideal root environment.
