Alien RDWC 9 Pot 20L Black Series

A compact recirculating system built for tight grow tent footprints

The ALIEN RDWC 9 Pot 20L Black Series is a recirculating deep water culture system for growers working with limited grow tent or grow room space. Circulating oxygen-rich nutrient solution between all nine 20L plant sites means faster nutrient uptake, stronger root development and none of the uneven growth or nutrient imbalances that come with separate feeding. The shared solution keeps EC and pH balanced across the whole system, supporting vigorous veg and dense, high-quality flowers from a genuinely compact footprint.

Key Benefits

• Nine-pot recirculating layout for compact indoor setups.
• Constantly oxygenated nutrient solution encouraging rapid root development.
• Shared circulation improving nutrient uptake across all plants.
• Balanced EC and pH maintained throughout the system.
• JET-STREAM SILENT 1.5 pump moving up to 1350 L/hr for continuous flow.
• Strong bud density from consistent feeding through to flowering.

How to Use

1. Assemble the system using the supplied pipework, spacing pots to the recommended 50cm plant centres.
2. Fit the JET-STREAM SILENT 1.5 water pump for continuous circulation between reservoir and plant sites.
3. Connect an external air pump (JET-45 recommended, purchased separately) with air stones for high dissolved oxygen at the roots.
4. Fill with water, add hydroponic nutrients and set correct EC and pH.
5. Place plants in net pots with an inert medium such as clay pebbles so roots reach the solution.
6. Check pH, EC and water levels regularly, and use a water chiller where necessary to keep temperatures stable.
