Description

Sixteen pots feeding as one, without the uneven growth

The Alien RDWC 16 Pot 20L Black Series is a compact recirculating deep water culture (RDWC) system for growers running tighter plant spacing who still want fast vegetative growth, efficient nutrient uptake and high yields. By constantly circulating oxygen-rich nutrient solution between each of the sixteen 20L pots and the header pot, every plant gets the same feed and stable root-zone conditions - keeping EC and pH balanced across the whole system and heading off the uneven feeding, slow growth and nutrient lockout that plague poorly circulated setups. Well-oxygenated roots drive vigorous veg and dense flowers in bloom.

Key Benefits

  • 16-pot recirculating layout for high-performance hydroponics
  • Oxygen-rich solution supports rapid root development
  • Constant circulation keeps EC and pH consistent across all plants
  • Compact 20L pots suited to indoor grow tent and grow room setups
  • Strong veg and heavier flowering from a stable, well-fed root zone
  • Durable professional-grade build for reliable long-term use

How to Use

  1. Assemble the system with the supplied pipework, arranging pots to the recommended spacing.
  2. The JET-STREAM SILENT 1.0 water pump comes fitted in the header pot for constant circulation throughout the system.
  3. Connect a compatible external air pump (60 L/min, not included) with air stones to oxygenate each pot.
  4. Fill the system with water, add hydroponic nutrients and set the correct EC and pH.
  5. Place plants in net pots using an inert medium such as clay pebbles so roots reach the circulating solution.
  6. Monitor nutrient levels, pH and water temperature regularly through veg and flower.
  7. For best performance, use a water chiller to keep solution temperatures stable in the grow room.
