So, how does the IWS Standard Flood & Drain System work? It’s a complete nutrient delivery solution that can be arranged to fit any size grow room. This system is fully adaptable, and can be upgraded to add new pots at any time. Nutrient is pumped from the Flexi tank and out to the IWS Brain at user-specified times and durations, which are set on the IWS Minute Timer.

In summary

The Brain connects to the containers in the system through 13mm pipework. As it fills up, so do all of the containers. A float switch sits inside the Brain, which turns the nutrient flow from the tank off when the water level gets too high. The float height is the same as the top of the containers, preventing the system from ever flooding.

Each pot consists of two parts – an Inner and an Outer pot. The IWS Outer Pot connects to the pipework in the system, filling up with nutrient solution as the system floods. The inner pot sits inside the outer, and is perforated with holes. It contains the substrate and root-mass. As the outer fills up with nutrient, the root zone becomes saturated.

The IWS Standard Flood & Drain System provides a fully automated feeding solution that anyone can easily set up and operate.You can control feed times precisely with it, and you can arrange it to fit any size grow room. With its efficient design and easy operation, this system is the perfect choice for hydroponic growers of all levels. So, what are you waiting for?
