Attach the necessary fittings to the pots.

2. Connect the System

Use piping to connect the pots and the header pot to establish the recirculating network.

Set up the air pump and connect it to the air stones in the pots.

4. Integrate Pumps

Install the water pump(s) for recirculation and chilling (if applicable).

5. Set Up Nutrient Tank

Connect the nutrient tank to the system.

6. Fill the System

Add water to the system.

Maintenance Tips:

  • Maintain water temperature between 18-20°C (64-68°F).
  • Add nutrients to the system and allow for recirculation before testing and adjusting.
  • When planting, use a substrate layer in the net pot, water the cutting, and fill the remaining space with substrate.
  • Fill the system using a hose, ensuring the correct level before turning on the pump.
  • Drain the system as needed by connecting a pipe to the designated fitting.
  • Use preventative solutions to maintain root health and system cleanliness.

FAQs

What is the main advantage of an RDWC system?+

A Recirculating Deep Water Culture (RDWC) system constantly circulates highly oxygenated nutrient solution through the plant's root zone. This leads to explosive root growth, faster vegetative cycles, and significantly larger yields compared to many other methods.

Is this system difficult to assemble?+

No, the Alien RDWC system is designed for easy, tool-free assembly. It uses threaded fittings and snap-on pipes, so no glue is required. This makes setup, reconfiguration, and maintenance straightforward for growers of any experience level.

What's the difference between the 20L and 36L pot options?+

The primary difference is the volume available for root development. The larger 36L (9.5-gallon) pots are ideal for growing larger plants or mother plants that require more space for an extensive root system, while the 20L (5-gallon) pots are excellent for most standard applications.

Can this system be expanded or modified later?+

Absolutely. The modular design is a key feature of the Alien Hydroponics systems. You can easily add more pots, adjust spacing, or reconfigure the layout to fit a new space or expand your operation. If you need a different starting size, we also offer systems like the 36 Pot 3 Row RDWC.

How does the RDWC system compare to the Alien V-SYSTEM?+

Both are high-performance systems. The RDWC uses JET-STREAM A.I.R.™ rings for oxygenation, while the V-SYSTEM uses a venturi pump to create a vortex, drawing oxygen directly into the water. The V-SYSTEM is known for its complete drainage and external pump, while the RDWC is a versatile and powerful deep water culture classic. The best choice depends on your specific growing style and goals.
