Who This Is For
- You are upgrading to a 16-pot system because your current hand-watered setup makes growth rates too unpredictable.
- You are scaling to a 4-row layout because managing separate reservoirs for each plant takes up too much of your time.
What We Found
- Those oversized two inch fittings are the real hero here because they handle massive root balls without clogging.
- The silver polymer pots keep the solution noticeably cooler than standard black buckets under high intensity lights.
What Users Say
- Growers who switched from drain to waste say they cut their nutrient costs by nearly half in the first full cycle.
- Users who moved to this 16 pot layout report they stopped worrying about root rot even during peak summer heat.

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 provide a constant flow of highly oxygenated, nutrient-rich water directly to the plant's roots. This leads to faster growth rates, healthier root systems, and significantly larger yields compared to many other hydroponic methods.
No, the system is designed for easy, tool-free assembly. It uses threaded fittings and snap-on pipes, so no glue is required. This makes setup, breakdown, and reconfiguration quick and simple.
The Alien Hydroponics systems incorporate unique, patented features like JET-STREAM A.I.R.™ rings for superior oxygenation and oversized Dual-Flow™ fittings that are specifically designed to prevent root clogging, ensuring your system runs smoothly and efficiently.
The system is constructed from a heat-reflective silver polymer that helps keep the nutrient solution cooler. For optimal results, maintain a water temperature between 64-68°F (18-20°C). In warmer environments, a water chiller may be beneficial.
Yes, the modular design allows for customization and expansion. You can reconfigure the layout or add more pots as your needs change. If you need a larger setup from the start, consider the Alien Hydroponics RDWC 20 Pot system or other available sizes.
The 36L (9.5-gallon) pots hold more water and provide more space for root development than the 20L (5-gallon) pots. This can be beneficial for growing larger plants or for growers who want a more stable system with less frequent pH and EC fluctuations.
