Who This Is For
- You are moving to a recirculating system because your current static deep water setup suffers from constant pH swings.
- You are upgrading to 2 inch fittings because your root masses are getting large enough to block standard tubing.
What We Found
- The 2 inch fittings are overkill in the best way, making it nearly impossible for roots to choke the flow.
- We noticed the silver pots stay significantly cooler under intense lighting compared to standard black buckets.
- Setup takes half the time of other RDWC kits because those threaded nuts actually lock down without any leaks.
What Users Say
- Users who switched from top-feed setups say their veg time dropped by two weeks due to the constant oxygenation.
- Growers mention they stopped checking every pot individually once they saw how stable the pH stays in this system.

Setup and Maintenance
System Setup Steps:
1. Prepare Pots
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.
3. Install Air System
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 64-68°F (18-20°C).
- Add nutrients and allow them to circulate fully before testing and adjusting pH/EC.
- When planting, use a substrate layer in the net pot, water the cutting, and fill the remaining space.
- Use preventative solutions to maintain root health and system cleanliness.

FAQs
What makes RDWC different from standard DWC?
Recirculating Deep Water Culture (RDWC) constantly circulates the water and nutrient solution throughout all the pots in the system. This keeps the pH, EC, and temperature uniform everywhere, preventing inconsistencies that can stress plants. Standard DWC hydroponics systems use standalone buckets, requiring you to manage each one individually.
Is this system difficult to set up?
No, the Alien RDWC system is designed for easy assembly. It features threaded fittings and snap-on pipes, so no glue or complex tools are required. The included instructions provide a clear, step-by-step guide to get you growing quickly.
What size grow tent is recommended for this system?
The 8 Pot 4 Row system has a flexible footprint. At its minimum size (44" x 67"), it can fit within a 4' x 6' or 5' x 5' grow tent. However, for optimal plant spacing and access, a larger tent like an 8' x 8' is recommended, especially if you plan to space the pots further apart.
Can I expand this system later on?
Absolutely. The modular design is one of the key benefits. You can add more pots or reconfigure the layout as your needs change. If you know you'll need more space, you might consider starting with a larger kit like the Alien Hydroponics RDWC 12 Pot 4 Row system.
What is the difference between this and the Alien V-SYSTEM?
The main difference is the oxygenation method. The RDWC uses JET-STREAM A.I.R.™ rings powered by an air pump, while the Alien V-SYSTEM uses a venturi effect created by the water pump, which means it doesn't require a separate air pump. Both are excellent systems, but they achieve super-oxygenation in different ways.
