Description
The ALIEN® RDWC 28 Pot 20L PRO Silver Series is a professional recirculating deep water culture (RDWC) hydroponic system designed for high-output indoor growing. By continuously circulating oxygen-rich nutrient solution through every plant site, the system maintains stable root zone conditions that promote rapid root development, vigorous vegetative growth and heavy flowering during the bloom stage.
With a system volume of 435L and a 280L CAMO® reservoir, growers can maintain consistent pH and nutrient levels across the entire hydroponic system. This helps prevent common grow room issues such as uneven plant growth, weak root systems and poor nutrient uptake. The system can be configured with a minimum footprint of 3m × 1.47m or expanded to 4.1m × 2.15m depending on pipe layout. Designed around 50–60cm plant centres, the layout is ideal for developing dense, even canopies in large grow tents or dedicated hydroponic grow rooms. With the highly oxygenated RDWC environment, growers can typically run shorter 7–10 day vegetative periods while still achieving strong flowering and high yields.
The system uses the JET-STREAM™ SILENT 2.0 circulation pump, delivering up to 2150 L/hr while using 32W, ensuring constant nutrient movement throughout the system. For optimal oxygenation, the recommended JET-200 air pump provides 200 L/min of airflow at 210W, helping maintain high dissolved oxygen levels essential for healthy root systems, strong plant health and improved bud density during flowering.

• Promotes rapid root development and vigorous vegetative growth
• Supports heavy flowering, improved bud density and higher yields
• CAMO® reservoir helps stabilise pH and nutrient levels across the system
• Powerful circulation pump ensures even nutrient distribution
• High dissolved oxygen levels support strong plant health
• Ideal for large grow rooms and high-performance hydroponic systems
How to Use
-
Position the RDWC system in your grow tent or grow room according to the recommended footprint and plant spacing.
-
Connect all pots using the supplied pipework and link them to the CAMO® reservoir.
-
Install the JET-STREAM™ SILENT 2.0 water pump in the reservoir to circulate nutrient solution through the system.
-
Connect a suitable high-output air pump (such as the recommended JET-200) to provide strong aeration to the root zones.
-
Fill the reservoir with water and add hydroponic nutrients suitable for RDWC hydroponic systems.
-
Adjust and maintain pH and EC levels according to the plant stage, from vegetative growth through to the bloom stage.
-
Maintain strong aeration and stable water temperatures, using a water chiller if necessary, to maximise nutrient uptake, root development and final yield.
Important: Air pump must be purchased separately.
