Alien RDWC 28 Pot 20L Black Series

The ALIEN® RDWC 28 Pot 20L Black Series is a large-scale recirculating deep water culture hydroponic system built for growers who want powerful plant growth, strong root development and consistently high yields in professional indoor growing environments. By continuously circulating oxygen-rich nutrient solution throughout the entire hydroponic system, each plant receives equal access to nutrients and oxygen, helping maintain balanced root zone conditions across every pot.

This RDWC system allows growers to manage larger plant numbers while maintaining stable EC and pH levels throughout the grow room or grow tent. Constant nutrient circulation improves nutrient uptake and helps prevent common hydroponic grow problems such as slow vegetative growth, uneven feeding or weak root systems. With highly oxygenated roots and steady nutrient delivery, plants can develop rapidly during vegetative growth and produce dense flowers with improved bud density and yield during the bloom stage.

Key Benefits

• High-capacity recirculating deep water culture system for large hydroponic setups
• Continuous nutrient circulation ensures balanced feeding across all plants
• Oxygen-rich root zones support strong root development and plant health
• Helps maintain stable EC and pH throughout the hydroponic system
• Ideal for large indoor growing environments and organised grow rooms
• Supports vigorous vegetative growth and improved yields during flowering

How to Use

1. Assemble the RDWC system using the supplied pipework, positioning pots according to the recommended plant centres.

2. Install the JET-STREAM™ SILENT 2.0 water pump to maintain constant circulation of nutrient solution throughout the hydroponic system.

3. Connect a suitable external air pump (JET-100 recommended) with air stones to supply high dissolved oxygen levels to the root zones.

4. Fill the reservoir with water and add hydroponic nutrients suitable for hydroponic systems, maintaining correct EC and pH levels.

5. Place plants in net pots using an inert medium such as clay pebbles and ensure roots can reach the circulating nutrient solution.

6. Monitor EC, pH and water levels regularly to maintain optimal nutrient uptake during vegetative growth and the bloom stage.

7. For best results, maintain stable nutrient solution temperatures using a suitable water chiller where necessary.
