ALIEN® RDWC 9 Pot 20L PRO Silver Series

The ALIEN® RDWC 9 Pot 20L PRO Silver Series is a professional recirculating deep water culture hydroponic system designed for fast growth, powerful root development and consistent results in indoor growing environments. Built using the proven ALIEN® PRO system design, this RDWC setup keeps nutrient solution constantly circulating between all pots, delivering oxygen-rich nutrients directly to the root zone for rapid vegetative growth and heavy flowering.

With balanced nutrient distribution across all plant sites, the system helps prevent common hydroponic issues such as uneven feeding, slow growth and weak root systems. The JET-STREAM™ SILENT water pump maintains strong circulation, ensuring every plant receives the same nutrient solution for consistent plant health and uniform yields across your grow tent or grow room.

The compact yet highly productive layout makes it ideal for growers who want to run multiple plants in hydroponic systems while maintaining strong root oxygenation and efficient nutrient uptake.

How to Use

1. Assemble the RDWC system according to the manufacturer’s instructions and ensure all pipe connections are secure.

2. Fill the control tank with water and add hydroponic nutrients suitable for RDWC or recirculating hydroponic systems.

3. Adjust pH and EC levels according to your plant stage (vegetative growth or bloom stage).

4. Place plants into net pots using clay pebbles or another hydroponic growing medium.

5. Connect a compatible air pump (recommended JET-100 air pump – 100L/min output) to air stones to provide strong root oxygenation.

6. Switch on the JET-STREAM™ SILENT water pump to begin circulating nutrient solution throughout the hydroponic system.

7. Monitor pH, EC and water levels regularly to maintain healthy root zones and maximise yield and bud density.
