Simply plugin and grow with our next generation RDWC system. Growing top-quality plants indoors has never been so effortless, combining our ground-breaking technology with the classic deep water culture method.

Available in either the "Black Series" or "PRO Silver Series", the ALIEN® RDWC recirculating deep water culture system provides excellent results, fast vegetation times and high plant yield, reducing growing time and increasing profit for you.

The RDWC works using the quietest JET-STREAM™ A.I.R™ pumps to increase oxygen delivery to the plant's roots submerged in the nutrient-rich water. The JET-STREAM™ A.I.R™ pumps have been designed with Deep Water Culture in mind and boast a high pressure to deliver oxygenated water to the root zone.

The pump also features a double dampening system for noise absorption, and the twin air chambers provide a large quantity of air at an intense pressure to the Air Rings ™ while still retaining low noise and wattage. With a large volume of nutrient solution in the system, the only thing you need to do is maintain the PH and EC levels and plan your next crop. It's that easy.

The system fittings are threaded and secured with rubber washers and nuts, making system installation and relocation easier. Heavy-duty clips situated on the sides of the pots elevate the airlines off the floor. All RDWC systems come with factory-fitted chiller fittings on the side of the header, making chiller installation simple.
CAMO® Tanks are an optional add-on and ensure the optimum nutrient solution level is maintained.

What’s the difference between the “Black Series” and “PRO Silver Series”?

PRO Silver Series features

The patent-pending Dual-Flow™ fittings are an oversized 50mm for a more free-flowing system. These fittings are over 3x the internal size of the 32mm.


Heat-reflective silver 50mm pipe is used vs the Black Series green 32mm.

Ball valves and heavy-duty inline filters are included with the Silver Series.


The pots and lids are also produced from heat-reflective silver polymer. This helps keep nutrient solution temperatures cooler and relieves the water chiller from working as hard.

The PRO Silver Series incorporate JET-STREAM A.I.R™ (Air Injection Rings). Air pump and airline sizes are increased to supply the Rings with a strong pressure to achieve maximum oxygen saturation.


Recirculating Deep Water Culture is a method used to grow plants with roots submerged in a highly oxygenated nutrient solution.

By using the ALIEN® RDWC hydroponic system, you can optimise maximum growth potential. The super oxygenated nutrient solution is constantly recirculating around the system. The pump creates a water current that draws the solution through the pots, mixing the nutrients. This current also delivers vital nutrients to the roots, optimising root health and increasing nutrient uptake efficiency. Importantly, PH and EC levels are continuously maintained due to the high volume of water contained in the system.


Using the 4 hole lid is an ideal way to establish cuttings or seeds in the vegetative stage. This is a far more efficient use of space than placing small plants in a single hole lid, and one plant occupying the whole grow room for 2-4 weeks.

Once plants are around one week or less away from flowering, transfer the square net pots into single hole lids and place them in the flowering room for the last week of the vegetative stage.

Made of 3mm thick ABS plastic, the lid can also take the weight of 4 fully grown plants if needed.
