Want extreme & uniform growth in a system that's easy to manage? You need a Recirculating & Dumpback R-DWC System.

  • Uses 19L Oxypots
  • Expandable up to 24 pots
  • DWC growing method (high oxygen, max growth!)
  • Recirculating & dumpback (stable, fresh feed)

What is it?

It's a recirculating DWC system - roots grow straight into an oxygen and nutrient rich solution that’s constantly travels from pot to pot


As it circulates, your feed mixes and cools along the way:

  • Your pH, temperature & CF stays stable 
  • Oxygen gets trapped in your feed


To keep your feed fresh, a remixing timer is included

At your chosen times, feed is sent back to your tank. Here, it mixes with all the feed in your tank

  • Keeps your nutrient fresh
  • Helps to cool your nutrient
  • Keeps temperature, CF & pH stable

We recommend

To run your system, you need airstones, airline and an air infusion pump. Save time & money - buy as R-DWC Air Kit.



Bigger, faster growing plants

Plants have unlimited access to nutrients and water. And there's lots of oxygen to speed up nutrient uptake & growth!  

Healthy Roots, No Diseases

All the oxygen keeps roots healthy..bett yet, most root diseases can't thrive in an oxygen rich environment.

Stable pH, CF & Temperature

Your feed is constantly mixed! There's always the same nutrient profile in all pots. You can even rotate pots for even light exposure

Uniform growth

Feed mixes as it circulates - this keeps your pH, CF, temperature stable. At set times, your feed is mixed with fresh feed in your tank.

Quiet to run

The pump's hardly ever on and air stones won't rattle.

Easy to manage

Hardly any media's needed and you've only got one tank to manage.
