Who This Is For
- You are moving to a large 20 pot system because managing individual reservoirs is wasting too many labor hours.
- You are switching to RDWC because your current stagnant water setup causes nutrient lockout and root health issues.
- You are choosing a modular layout because your facility space requires a custom row configuration to fit the floor.
What We Found
- The silver polymer lids and pots actually keep solution temps several degrees lower than standard black plastic ones.
- Skipping the glue for these threaded fittings makes it much easier to reconfigure your layout between crop cycles.
What Users Say
- Growers who scaled up from smaller rigs say the growth rate stays just as explosive even with twenty plants running.
- Facilities using the 2-inch Dual-Flow lines say they stopped losing plants to plumbing clogs during peak flowering.
Alien Hydroponics RDWC - 20 Pot 4 Row
Struggling to achieve consistent, large-scale results without the headache of complex maintenance? The Alien Hydroponics RDWC 20 Pot 4 Row system is the ultimate solution for commercial growers and serious hobbyists who demand explosive growth and maximum efficiency. By constantly recirculating super-oxygenated nutrient solution directly to the root zone, this system eliminates the common pitfalls of stagnant water and nutrient lockout.
Built for performance, this Alien Hydroponics system provides the abundant oxygen required for massive root development and faster flowering cycles. Whether you are transitioning from a smaller setup like the Alien Hydroponics RDWC - 4 Pot 2 Row or building a new commercial facility, the modular design ensures you can adapt to any space. Its unique construction prevents root clogging and oxygen deficiency, ensuring every one of your 20 plants reaches its full genetic potential.
Customization is at the heart of this system. Choose between 5-gallon (20L) or 9.5-gallon (36L) pots and select a compact or remote header to fit your specific grow room layout. With tool-free, no-glue assembly, setting up your professional recirculating deep water culture (RDWC) system is faster and easier than ever before.

Alien Hydroponics 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 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
Recirculating Deep Water Culture (RDWC) systems super-oxygenate the nutrient solution that is constantly circulated around the root zone. This high level of dissolved oxygen promotes rapid nutrient absorption, leading to explosive root development, faster vegetative growth, and significantly larger yields compared to static DWC methods.
This is a 20-pot system, designed to accommodate 20 individual plants. The 4-row configuration helps maximize plant count in a defined rectangular space while ensuring all plants receive equal nutrient and oxygen distribution.
No, the Alien Hydroponics RDWC system is designed for ease of use. It features threaded fittings and snap-on pipes that require no glue or specialized tools, making setup and reconfiguration straightforward for growers of all levels.
Absolutely. The modular design allows for easy expansion. You can scale up from a smaller Alien Hydroponics RDWC - 8 Pot 1 Row or expand this current setup to even larger commercial configurations like the Alien Hydroponics RDWC - 36 Pot 4 Row.
The footprint is flexible. Depending on pot size and header choice, the minimum size is approximately 85" x 67" and can be expanded up to 189" x 145" for larger plants. Always refer to the specifications table for exact dimensions based on your chosen configuration.
