Description
Professional RDWC sized for a fast, uniform medium canopy
The ALIEN® RDWC 15 Pot 20L PRO Silver Series is a professional recirculating deep water culture system for growers chasing fast growth and consistent yields from a medium indoor setup. With 15 x 20L pots and a system volume of 240L, it circulates oxygen-rich solution through every pot to hold pH and nutrient levels stable across all sites, heading off the uneven growth you get when pots drift out of sync. The highly oxygenated root zone even supports short 7-10 day veg periods, moving plants quickly into flower while keeping strong structure.
Key Benefits
- 240L system volume for stable pH and EC across all 15 sites
- 15 x 20L pots supporting rapid root development and an even medium-sized canopy
- JET-STREAM™ SILENT 1.0 pump delivering up to 950 L/hr on just 16W for consistent nutrient movement
- 150 L/min air requirement (air pump not included) for the dissolved oxygen that drives roots and flower density
- Flexible footprint from 2.25m x 1.1m up to 2.9m x 1.55m, with 50cm plant centres recommended
- Short 7-10 day veg possible thanks to the oxygen-rich RDWC environment
How to Use
- Position the system in your grow tent or room to the recommended footprint and plant spacing.
- Connect all pots to the header pot with the supplied pipework; with a Tank option, link the CAMO® tank to the header pot's float valve.
- The JET-STREAM™ SILENT 1.0 pump comes fitted in the header pot to circulate nutrient solution.
- Connect a suitable air pump of 150 L/min (sold separately) to the A.I.R. injection rings to aerate the root zones.
- Fill with water, add nutrients suitable for RDWC, then set and maintain pH and EC through veg and bloom.
- Keep aeration strong and water temperature stable, using a chiller if needed, to maximise uptake, roots and yield.
