Description

Nine pots, one balanced feed, built for serious canopies

The Alien RDWC 9 Pot 36L PRO Silver Series is a professional recirculating deep water culture (RDWC) system for growers tired of uneven feeding and inconsistent roots across multiple pots. Oxygen-rich nutrient solution circulates continuously between all nine 36L modules and the header pot, so every plant draws the same balanced feed and nutrient uptake, root health and vigour stay consistent from veg through to heavy flower. The PRO Silver Series pots reflect light away from the root zone, helping keep water temperature stable and roots protected from stress.

Key Benefits

  • Nine-site recirculating layout with 36L modules for explosive root growth
  • Central header pot to manage nutrients for the whole system from one point
  • Silver Series reflective pots that help hold stable root-zone temperatures
  • Highly oxygenated circulation improving nutrient uptake at every plant site
  • 250L system volume for stable feeding, with an optional 120L CAMO top-up tank
  • Scalable footprint from 1.7m x 1.35m up to 2.3m x 1.9m for high-yield rooms

Uneven feeding and slow roots across multiple plants?

Running several plants often means inconsistent feeding, poor root development and slow growth. RDWC fixes this by circulating oxygenated nutrient solution so every plant gets the same balanced feed. The Alien system floods the root zone with oxygen to prevent root stress and drive rapid vegetative growth, giving stronger plants, heavier flowering and far higher yields than soil or coco.

How to Use

  • Assemble the system and connect all nine plant modules to the header pot using the supplied pipework.
  • Fit the JET-STREAM SILENT 1.5 water pump (1350 L/hr, 23W) to circulate nutrient solution.
  • Connect a suitable air pump of 90 L/min (sold separately) to the A.I.R. injection rings for constant oxygenation.
  • Fill the system, add hydroponic nutrients and set EC and pH to your feeding schedule.
  • Allow 10-14 days of veg before flipping to flower, keeping water temperature stable (a 300L chiller is recommended).
  • Check the solution in the header pot daily and adjust nutrients as plants move from veg into flowering.
