Black Series RDWC Systems from Alien Hydroponics

120 liters of nutrient solution, 4 to 12 high-quality pots, a powerful pump and an ingenious design - Alien Hydroponics brings out the heavy guns with the Black Series RDWC system. This is also necessary: After all, the British manufacturer promises you a shortening of the growth phase to a brisk 7-10 days

This is achieved by a determined application of the successful "Recirculating DWC" principle. Your plants root exclusively in the nutrient solution and are irradiated by a fine air stream to prevent rot. This way, they not only receive the maximum amount of nutrients, but are also supplied with enough oxygen to shoot up healthily and splendidly

The solution itself circulates through all the pots, driven by the included pump, so that you have a uniform pH and EC value on each plant. To avoid bottlenecks, you have a well-sealed 120-liter tank that supplies your system with replenishment around the clock. The airflow pump, which is also included, provides the air supply to the roots.

Depending on the variant, you should plan enough space for your irrigation system. The minimum areas are WITHOUT TANK:

  • For 4 plants: 1.3 x 0.9 m
  • For 6 plants: 1,7 x 0,9 m
  • For 8 plants: 2,1 x 0,9 m
  • For 10 plants: 2,6 x 0,9 m
  • For 12 plants: 1,7 x 1,8 m

WITH tank you should be able to occupy at least the following area:

  • For 4 plants: 1,6 x 1,2 m
  • For 6 plants: 2,3 x 1,2 m
  • For 8 plants: 3,0 x 1,2 m
  • For 10 plants: 3,4 x 1,2 m
