IWS R-DWC System

iws r-dwc system

Up to 24 pots can be linked to one water butt in this recirculating deep water culture system so that plants roots remain submerged and fed.


With two recirculating options available there’s an IWS R-DWC to suit your needs.

IWS R-DWC is very flexible, the misting chambers can be spaced as far apart or as close together as you choose and extra chambers can be added over time, so you can start small and scale up as you get more experienced.

If you choose the entry level IWS R-DWC you will need to change the solution in the water butt every week to keep it fresh.

For a simpler life the Pro IWS R-DWC has a timer which remixes the solution every day, sending the solution from the mixing chambers, back to the water butt, automatically keeping the mix balanced, oxygenated and cool.

hints and tips

We recommend changing your nutrient solution once a week, as the nutrient strength (EC) rises over time. Drain the tank completely and replace with fresh nutrient to keep your plants healthy and get optimum results.
