DWC system - 21 x 20L

The latest generation of ALIEN® RDWC systems introduces many new features.

Fittings are now threaded and secured with rubber washers and nuts, making it easier to install and move the system. Sturdy clips on the sides of the pots allow it to be lifted off the ground.

The hydroponic baskets have been significantly improved and are now made from the Supersoft™ material to prevent possible root damage. The square design is suitable for rockwool cubes, but remains circular on the outside, so rotation is still possible. The base includes a raised grille to slightly raise the system to prevent it from becoming too saturated.

All RDWC systems are now equipped with a connection that simplifies the installation of a cooler on the side of the collector.

The new Jet-Stream™ turbines have been designed with Deep Water Culture in mind and deliver high pressure while maintaining low noise and power consumption. They have a double noise reduction system and the twin air chambers produce a large amount of air at high pressure.


Optional tank
Alien recommends a 280L tank for this system.
