Alien RDWC 4 Pot 36L PRO Silver Series

The Alien RDWC 4 Pot 36L PRO Silver Series is a professional recirculating deep water culture hydroponic system designed for growers who want rapid vegetative growth, explosive root development and consistently high yields in indoor growing environments. Built with Alien’s heavy-duty PRO Silver Series components, this system delivers highly oxygenated nutrient solution directly to the root zone, helping plants grow faster and stronger throughout the entire grow cycle.

Using a central reservoir and powerful circulation pump, nutrients are constantly recirculated through each pot to maintain stable EC, pH and nutrient availability across the entire system. This ensures every plant receives the same feeding conditions, reducing uneven growth and helping maximise plant health, flowering performance and bud density.

Key Benefits

• Recirculating deep water culture system designed for fast hydroponic growth
• Highly oxygenated root zone supports aggressive root development
• Consistent nutrient delivery across all pots for uniform plant growth
• Large pot capacity supports bigger plants and higher yields
• Professional PRO Silver Series components for durability and reliability
• Ideal for grow tents and dedicated grow room setups
• Works with clay pebbles and other hydroponic media

How It Solves Grow Problems

Many growers struggle with slow growth, weak root systems and inconsistent feeding when using basic hydroponic systems. The Alien RDWC design constantly circulates nutrient solution between the reservoir and plant sites, preventing stagnant water and improving nutrient uptake.

When paired with a suitable air pump, the system delivers high dissolved oxygen levels that support strong root development and vigorous vegetative growth. Healthy roots allow plants to absorb nutrients more efficiently, resulting in stronger flowering, improved bud density and higher overall yields.

The system layout also keeps plant spacing consistent, making it ideal for controlled indoor growing setups.

How to Use

1. Assemble the RDWC system and connect all pots to the main reservoir using the supplied pipework.

2. Fill the reservoir with water and add hydroponic nutrients according to your feeding schedule.

3. Install an air pump and air stones to oxygenate the nutrient solution (required for proper RDWC operation).

4. Place plants into net pots filled with clay pebbles or another suitable hydroponic medium.

5. Switch on the circulation pump to begin recirculating the nutrient solution throughout the system.

6. Maintain correct pH and EC levels and regularly top up the reservoir to support healthy vegetative growth and flowering.
