IWS DWC - The Modular Oxypot

Up to 36 pots can be linked to one water butt in this IWS deep water culture system so that plants roots remain submerged and fed.



How the IWS DWC system works
The IWS DWC pumps solution from the control unit into each of the misting chambers where the air stones oxygenate the solution.

The timer controls how often the solution is pumped back to the water butt where it mixes with the water butt contents.

This remixing keeps the nutrients balanced the pH and EC stable and the solution cool.

Pots can be spaced out how the grower chooses and pots can be added at a later date.

The IWS DWC can be linked to chillers so growers who struggle to control the temperature in their environment can benefit from deep water culture.

Why They are Great

Perfect for growers who want:

  • Bigger yields - Plants have constant access to highly oxygenated nutrient solution so root growth is fast and extensive and yields are huge. Clay pebbles are used in DWC systems so even the roots in the media have excellent access to oxygen.
  • To set and leave - IWS DWC is a very low maintenance system and as it connects to a large water butt, can go for long periods before top-ups are needed.
  • Quiet running - Locators in the misting chambers keep the air stones in place so there’s zero rattling noise from air stone movement.
  • Low media usage - Each pot only holds 1 litre of media but these grow systems outperform others using far more media.
  • Access to roots - Every misting chamber has an access panel making it easy to check root health, water levels and air stone position.
  • To turn plants under lights – Each pot can be lifted and turned within the misting chamber without twisting pipe or connectors to provide every plant with even light exposure.


  • Space the pots to suit the grow room.
  • IWS DWC system is available from 6 to 36 pots.
  • Each pot is 19 litres.

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.
