ALIEN® RDWC 18 Pot 20L PRO Silver Series

The ALIEN® RDWC 18 Pot 20L PRO Silver Series is a professional recirculating deep water culture (RDWC) hydroponic system designed for growers looking to run larger indoor growing setups with fast plant development and consistent yields. By continuously circulating oxygen-rich nutrient solution between every plant site, the system maintains highly stable root zone conditions that support rapid root development, vigorous vegetative growth and heavy flowering during the bloom stage.

With a system volume of 300L and a 280L CAMO® reservoir, growers can maintain balanced nutrient levels and stable pH across the entire hydroponic system. This helps prevent common grow room problems such as uneven growth, weak root systems and poor nutrient uptake. The system can be arranged within a minimum footprint of 2.6m × 1.1m or expanded up to 3.5m × 1.55m depending on pipe configuration and spacing. Designed around 50–60cm plant centres, this layout works well in larger grow tents or dedicated hydroponic grow rooms, allowing growers to build dense canopies while running shorter 7–10 day vegetative cycles.

The system is powered by the JET-STREAM™ SILENT 2.0 circulation pump, delivering up to 2150 L/hr while using 32W, ensuring strong and consistent nutrient movement throughout the system. For optimal root oxygenation, the recommended JET-150 air pump delivers 150 L/min of airflow at 125W, helping maintain high dissolved oxygen levels essential for strong plant health, vigorous growth and improved bud density during flowering.

Key Benefits

• Professional RDWC hydroponic system for medium to large indoor growing setups
• Recirculating nutrient solution ensures consistent nutrient uptake across all plants
• Promotes rapid root development and vigorous vegetative growth
• Supports dense flowering, improved bud density and higher yields
• CAMO® reservoir helps stabilise pH and EC levels across the system
• Powerful circulation pump ensures even nutrient distribution
• High oxygen levels support strong root health and plant performance
• Ideal for grow tents and hydroponic grow rooms focused on yield

How to Use

1. Position the RDWC system in your grow tent or grow room according to the recommended footprint and plant spacing.

2. Connect all pots using the supplied pipework and link them to the CAMO® reservoir.

3. Install the JET-STREAM™ SILENT 2.0 water pump in the reservoir to circulate nutrient solution throughout the hydroponic system.

4. Connect a suitable air pump (such as the recommended JET-150) to supply strong aeration to the root zones.

5. Fill the reservoir with water and add hydroponic nutrients suitable for RDWC hydroponic systems.

6. Adjust and maintain pH and EC levels according to plant stage, from vegetative growth through to the bloom stage.

7. 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.
