Description

Compact professional RDWC for a dense, uniform canopy

The ALIEN RDWC 12 Pot 20L PRO Silver Series is a compact professional recirculating deep water culture system for fast growth and consistent yields from a medium indoor setup. Its 12 x 20L pots circulate one shared body of oxygen-rich nutrient solution, and with a 200L system volume pH and nutrient levels stay stable across every site, preventing the uneven growth and nutrient imbalances a dozen unlinked pots drift into. Arrange it from a minimum 1.5m x 1.47m footprint up to 1.7m x 2.15m on 50cm plant centres, and the heavily oxygenated root zone supports short 7-10 day vegetative periods before flowering.

Key Benefits

  • 200L recirculating volume for stable pH and nutrient levels across all 12 pots
  • JET-STREAM SILENT 1.0 pump delivering up to 950 L/hr on just 16W
  • 120 L/min aeration from a suitable air pump (not included) keeps dissolved oxygen high for strong roots
  • Space-efficient footprint from 1.5m x 1.47m up to 1.7m x 2.15m, with 50cm plant centres recommended
  • Fast turnaround with 7-10 day veg periods into flowering
  • Dense flowering and improved flower density from consistent nutrient uptake

How to Use

  1. Position the system in your grow tent or room to the recommended footprint and plant spacing.
  2. Connect the pots to the header pot with the supplied pipework; with a Tank option, link the CAMO tank to the header pot's float valve.
  3. The JET-STREAM SILENT 1.0 pump comes fitted in the header pot to circulate nutrient solution through the system.
  4. Connect a suitable air pump of 120 L/min (sold separately) to the A.I.R. injection rings to aerate the root zones.
  5. Fill the system with water and add nutrients suitable for RDWC hydroponic systems.
  6. Set and maintain pH and EC by growth stage, from veg through to bloom.
  7. Keep aeration strong and water temperature stable, using a chiller where needed, to maximise uptake, roots and yield.
