Discover the new Alien RDWC* or *Recirculating Deep Water Culture hydroponic system which is a hydroponic method for growing plants with their roots submerged in a highly oxygenated nutrient solution.

How does an Alien RDWC hydroponic system work ? Using the Alien RDWC hydroponic system , you can maximize the growth potential of your plants thanks to the super-oxygenated nutrient solution, which is constantly recirculated by a pump. The constant circulation of water provides essential nutrients to the roots, optimizing root health and increasing the efficiency of nutrient uptake. It is important to note that the PH and EC levels are continuously maintained. Design RDWC Hydroponic Systems
of 20 liters are connected to each other with a row of tubes and fittings of 32 mm. This allows for a free flow system that continuously circulates the nutrient solution several times per hour. The larger diameter tube has been installed to combat the root clogging problem.

Air lines are attached to each pot to aerate the solution.

The 20 liter air kits use Hailea V-series pump which runs quietly.


The pots have pre-drilled holes. A pair of quality pipe cutters are supplied with each system. No other tools are needed. We use our own specially designed grommets to ensure secure and watertight connections to
