The IWS Flood and Drain System is a highly developed hybrid ebb and flow system, which works by flooding from the bottom of each individual 10.3 litre pot.

The system uses gravity to send water to the pots and only uses pumps to fill and drain the main 25 litre control bucket.

This has two quality magnetic float valves mounted inside to control the power to the pumps in both the tank and the controller bucket.

These floats control the flood level in the growing medium precisely to stop any over watering or flooding.

As the water is forced through the growing medium, it expels all the stale air in the medium surrounding the root ball and replaces it with fresh oxygen as it drains away.
