Alien Hydroponics RDWC - 12 Pot 2 Row

Struggling with complex hydroponic setups that fail to deliver consistent, professional-grade results? The Alien Hydroponics RDWC 12 Pot 2 Row Kit is engineered to eliminate the guesswork and maximize your growth potential. By utilizing a high-performance recirculating deep water culture (RDWC) design, this system provides a constant stream of super-oxygenated nutrient solution directly to the root zone. This prevents root clogging and stagnation, unlocking explosive growth and significantly heavier yields for both home enthusiasts and commercial growers.

This modular system is built for versatility, allowing you to customize your layout with flexible headers and choose between 5-gallon or 9.5-gallon pots to suit your specific crop needs. Transitioning to professional hydroponics is seamless thanks to the tool-free, no-glue assembly. This 12-pot configuration is perfect for medium-sized grow rooms, but the modular nature means you can easily scale up or down with other configurations like the 4-pot or 14-pot systems within the Alien RDWC range.

FAQs

What are the main benefits of RDWC?+

Recirculating Deep Water Culture (RDWC) systems continuously circulate highly oxygenated nutrients through the root zone, promoting explosive root growth, faster cycles, and significantly larger yields compared to traditional methods.

Is this system difficult to assemble?+

No, the Alien RDWC system features threaded fittings and snap-on pipes, requiring no tools or glue for assembly. It is designed for quick setup and easy reconfiguration.

What air pump is required for this 12-pot system?+

If purchasing without an included pump, you will need a pump capable of delivering at least 31.7 gallons per minute (120 liters per minute) to properly oxygenate all 12 pots via the JET-STREAM A.I.R.™ rings.

How does the system manage nutrient temperature?+

The system is built from a heat-reflective silver polymer material that reflects radiant heat away from the solution, helping to maintain optimal, cooler root zone temperatures.

Can I expand my system later?+

Yes, the modular design is fully scalable. You can add more pots or reconfigure your layout as your grow space expands, with various larger kits like the 16-pot system available.
