Description
High-capacity RDWC circulation across 21 large-pot sites
The Alien RDWC 21 Pot 36L PRO Silver Series is a large-scale recirculating deep water culture system built for professional growers who need consistent plant growth, strong root development and high yields across a bigger room. By keeping nutrient solution constantly circulating between all 21 sites, it delivers oxygen-rich nutrients directly to the root zone for fast vegetative growth and productive flowering. The powerful JET-STREAM SILENT 2.0 pump keeps feeding balanced across every pot, avoiding the uneven feeding, slow growth and inconsistent development that large systems suffer without strong circulation.
Key Benefits
- Continuous nutrient circulation for improved uptake and consistent crop performance
- 36L pots at every site give roots plenty of space, supporting large, vigorous plants
- System volume of 550L for stable nutrient conditions
- JET-STREAM SILENT 2.0 pump circulates 2150 L/hr on just 32W
- Even distribution across all pots for uniform vegetative growth and flowering
- Durable PRO Silver Series build designed for long-term, scalable use
Eliminating uneven feeding in large hydroponic setups
In big rooms, uneven nutrient distribution leads to some plants racing ahead while others lag, producing inconsistent development and patchy yields. The Alien RDWC keeps solution moving constantly between all sites so every root zone gets the same oxygenated, well-mixed feed, supporting strong root development, better nutrient uptake and stronger flowering right across the canopy.
How to Use
- Assemble the system per the manufacturer's instructions, ensuring all pipework and connections are securely fitted.
- Fill the system with water and add nutrients suitable for RDWC or recirculating systems.
- Adjust EC and pH to suit the plant stage, whether vegetative growth or bloom.
- Place plants into net pots using clay pebbles or another hydroponic growing medium.
- Connect a compatible air pump (200L/min, sold separately) to the A.I.R. injection rings for strong root oxygenation.
- Turn on the JET-STREAM SILENT 2.0 pump to begin circulating solution through the system.
- Monitor water levels, EC and pH regularly to maintain plant health and maximise yield.
