Description
High-capacity RDWC for uniform canopies and heavy yields
The ALIEN® RDWC 21 Pot 20L PRO Silver Series is a recirculating deep water culture system built for large-scale indoor growing, constantly circulating oxygen-rich nutrient solution through all 21 plant sites to hold a stable root zone. That stability is what stops the uneven growth, poor nutrient uptake and root stress that creep in once a room scales past a handful of plants. With a system volume of 330L, pH and EC stay in step across the whole run, and the highly oxygenated environment lets you shorten veg to just 7-10 days while still finishing dense, even canopies.
Key Benefits
- 330L system volume stabilises pH and EC across all 21 pots, preventing drift between plant sites
- JET-STREAM™ SILENT 2.0 pump, 2150 L/hr on just 32W keeps nutrient solution moving evenly and quietly through the system
- Explosive root and vegetative growth from constant oxygen-rich circulation, supporting a 7-10 day veg period
- Heavier flowering and denser flowers thanks to consistent feeding and high dissolved oxygen right through bloom
- Flexible footprint from 3m x 1.1m up to 4.1m x 1.55m to suit your room layout, with 50cm plant centres recommended
- Air pump of 200 L/min (not included) delivers the high dissolved oxygen vigorous roots demand
How to Use
- Position the system in your grow tent or room to the recommended footprint, spacing pots at 50cm centres
- Connect all 21 pots to the header pot with the supplied pipework; with a Tank option, link the 280L CAMO® tank to the header pot's float valve
- The JET-STREAM™ SILENT 2.0 pump comes fitted in the header pot to circulate solution throughout the system
- Connect a high-output air pump of 200 L/min to the A.I.R. injection rings to aerate each root zone
- Fill with water, add nutrients suitable for RDWC, and set pH and EC to plant stage from veg through bloom
- Keep water temperatures stable and aeration strong to maximise nutrient uptake, root health and final yield
