Intelligent Watering Systems manufacture the best hydroponic flood and drain watering systems available on the market today. These IWS systems were built with the intention of being cost effective and easy to use, making them perfect for both the novice and the experienced hydroponic gardener.

Flood and drain systems are a very effective method of growing hydroponically, they're easy to maintain and free up a lot of your time that you would spend hand feeding your plants or preparing a solution.

The brain pot has two high-quality magnetic float valves to control the flood level in your growing medium and ensure your plants don't drown or dehydrate.

This Flood and Drain system from IWS takes the hassle out of feeding your plants, thanks to the dual timer control system your flood and drain system really doesn't have to take up much of your time. If you've never used a flood and drain system before then the IWS Flood and Drain System is a fantastic place to start and if you're a professional grower you know how good these systems are!
