Overview

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

You get faster nutrient uptake, healthier roots and better growth. Systems run 24/7 so no timer's needed and very little media so your system is easy to manage.

19L Oxypots
DWC growing method (high oxygen, max growth!)
Flexible layout: Expandable up to 24 pots
Recirculating & dumpback (stable, fresh feed)
Simple to assemble, with no timer needed

NOTE: To run your system, you need airstones, air line 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, 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.

Easy Access To Roots

Each misting chamber has an access panel you can use to quickly check root health, water levels and air stone position.

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.

What Is It?

It's a recirculating DWC system - roots grow straight into an oxygen and nutrient rich solution that constantly travels across pots.

RECIRCULATING

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

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

DUMPBACK

To keep your feed fresh, a remixing timer is included. At set times, feed is sent back to your tank. Here, it mixes with all the feed in your tank.

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

It's just what plants need for epic root growth, faster nutrient uptake, and bigger yields.

Top Tips

Keep your system sterile with Silver Bullet Roots

It kills 99.99% of root diseases and stays active in tanks for 5 weeks!

If you already use Oxy-Plus 11.9%, switch to Silver Bullet and you’ll save 55%.
