Description
Recirculating DWC performance sized for smaller tents
The Alien RDWC 4 Pot 20L Black Series brings the speed of recirculating deep water culture into a footprint that suits smaller grow tents and rooms. Constantly circulating nutrient-rich, oxygenated water through each of the four 20L plant sites drives rapid vegetative growth and strong root development, while all four pots drawing from the same 120L reservoir keeps EC and pH stable and heads off the uneven growth you get feeding plants separately. Roots suspended directly in oxygen-rich solution absorb water and nutrients far faster than in soil or coco, and the recirculating design keeps that solution moving rather than stagnant - avoiding the weak roots and nutrient imbalances that would otherwise hit bud density in flower.
Key Benefits
- Highly oxygenated root zone promoting strong, dense root mass
- Consistent feeding across all four plant sites from one reservoir
- Compact footprint ideal for smaller grow tents and rooms
- Rapid vegetative growth and improved flowering performance
- JET-STREAM SILENT 1.0 pump circulating up to 950 L/hr
- Durable Black Series components built for reliable long-term use
How to Use
- Assemble the system and connect all pots to the main reservoir using the supplied pipework.
- Fill the reservoir with water and add hydroponic nutrients to the manufacturer's feeding schedule.
- Install an air pump with air stones to oxygenate the solution (JET-35 recommended; required for RDWC operation).
- Place plants into net pots filled with clay pebbles or another suitable hydroponic medium.
- Switch on the circulation pump to begin recirculating the solution.
- Monitor pH, EC and water levels regularly through veg and flower.
