Description

Compact 6-pot RDWC performance without the footprint

The ALIEN RDWC 6 Pot 20L PRO Silver Series brings Alien's recirculating deep water culture design to a scale that fits comfortably in many grow tents and compact hydroponic rooms. Continuously circulating oxygen-rich nutrient solution between all six 20L pots keeps pH, EC and oxygen consistent at every site, so the uneven development, poor nutrient uptake and root stress that hit small setups just as hard as large ones are kept in check. The highly oxygenated root zone drives faster rooting, vigorous vegetative growth and denser flowering, while the durable PRO Silver Series pipework delivers strong, reliable water movement and the header pot makes nutrient levels easy to monitor and adjust.

Key Benefits

  • Six 20L pots in a compact layout suited to grow tents and smaller hydroponic rooms
  • Recirculating design keeps nutrient, pH and oxygen levels consistent at every site
  • Central header pot makes it easy to monitor and adjust nutrients across the whole system
  • PRO Silver Series pipework for strong, reliable, long-term water movement between pots
  • High root-zone oxygenation supports faster veg and heavier flowering with improved flower density

How to Use

  1. Position the system in your tent or room with adequate spacing between plant sites.
  2. Connect all pots with the supplied pipework and attach them to the header pot.
  3. The circulation pump comes fitted in the header pot to move nutrient solution around the system.
  4. Connect a suitable air pump to supply constant oxygen to the root zones.
  5. Fill with water and add nutrients suitable for RDWC or other hydroponic systems.
  6. Set pH and EC to the growth stage, from veg through to bloom.
  7. Maintain strong aeration and stable water temperatures to maximise uptake, root health and yield.
