Who This Is For
- You are upgrading to an RDWC system because your current top-feed setup creates nutrient hotspots and uneven growth.
- You are moving to a 12-pot configuration because managing individual reservoirs is eating up all your maintenance time.
- You are choosing silver heat-reflective pots because your nutrient solution gets too warm during the summer months.
What We Found
- The silver polymer actually keeps the nutrient solution several degrees cooler when room temperatures climb.
- Those oversized 2-inch fittings are the main reason we rarely hear about flood issues from root clogs.
- The tool-free layout is easy, but map your floor space first because these systems take up a large footprint.
What Users Say
- Growers tell us they shaved a full week off their vegetative cycle after switching to this high-oxygen system.
- Users who switched from top-feed systems say they stopped worrying about individual drippers getting clogged.
Alien Hydroponics RDWC - 12 Pot 3 Row
Struggling with slow plant growth or nutrient deficiencies in your current setup? The Alien Hydroponics RDWC 12 Pot 3 Row system is engineered to maximize your yield by providing a super-oxygenated nutrient solution directly to the root zone. This commercial-grade recirculating deep water culture (RDWC) system simplifies the growing process, ensuring consistent nutrient delivery and rapid vegetative cycles for both boutique commercial growers and dedicated hobbyists.
By maintaining a constant flow throughout the system, the Alien RDWC prevents root clogging and ensures that every plant receives the exact same nutrient levels. This modular system is built for versatility and can be easily adapted to your specific grow space. If you require a different configuration, check out the 14 Pot 2 Row layout or the high-efficiency 15 Pot 3 Row Rain System.

FAQs
What is the main advantage of an RDWC system?
Recirculating Deep Water Culture (RDWC) systems provide a constant flow of highly oxygenated nutrient solution directly to the plant's roots. This leads to explosive root growth, faster vegetative cycles, and significantly larger yields compared to standard DWC or soil-based methods.
Is this system difficult to set up?
No, the Alien RDWC system is designed for easy, tool-free assembly. The fittings are threaded and the pipes snap on, so no glue is required. This makes setup, breakdown, and reconfiguration quick and straightforward.
Can I expand this system later on?
Absolutely. The modular design is a key feature. You can easily add more pots or reconfigure the layout to fit a different space. For example, you can scale up to the 16 Pot 2 Row or even the massive 28 Pot 4 Row system.
What is the difference between the RDWC and V-SYSTEM?
Both are excellent DWC hydroponics systems, but they differ in their oxygenation method. The RDWC uses JET-STREAM A.I.R.™ rings powered by an air pump, while the V-System uses a venturi pump to create a vortex that draws air into the water.
How do the Dual-Flow™ fittings help my grow?
These patent-pending fittings are oversized (2") and feature unique slots that help prevent roots from clogging the pipes. This ensures that the nutrient solution flows freely and consistently throughout all RDWC hydroponic systems.
