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.

About PRO System

​

The IWS Pro system is a premium quality version of the already successful IWS flood and drain system.

We have been developing this system based on years of feedback from our customers; we’ve tested it thoroughly and had great results.

The idea behind the Pro system is to fill and drain as quickly as possible, it takes less than half the time of a normal system.

The main benefit of a Pro over a regular system is that the bigger sized systems fill and drain twice as quickly, giving you better control of your feed times and avoiding leaving your root mass submerged in nutrient solution for longer than needed;

​

The main differences of the pro system are listed here.

  • 7000ltr per hour nutrient feed pump

  • 25mm feed pipe and fittings

  • 2 drain pumps

  • Higher rated control boards for the larger pumps
