Setup and Maintenance
System Setup Steps:
- Prepare Pots: Attach the necessary fittings to the pots.
- Connect the System: Use piping to connect the pots and the header pot to establish the recirculating network.
- Install Air System: Set up the air pump and connect it to the air rings in the pots.
- Integrate Pumps: Install the water pump for recirculation.
- Fill the System: Add water and your nutrient solution.
Maintenance Tips:
- Maintain water temperature between 64-68°F (18-20°C).
- Always add nutrients to the system and allow for recirculation before testing and adjusting pH/EC.
- When planting, use a substrate layer in the net pot, water the cutting, and fill the remaining space with substrate.

FAQs
What is the main advantage of an RDWC system?
RDWC (Recirculating Deep Water Culture) systems provide constant aeration and nutrient circulation to the root zone. This results in explosive growth, healthier plants, and significantly higher yields compared to traditional methods. The Alien Hydroponics design enhances this with superior oxygenation.
Is this 18-pot system difficult to assemble?
No, the system is designed for easy, tool-free assembly. It uses threaded fittings and snap-on pipes, so no glue is required. You can set up or reconfigure the entire system quickly and easily.
What size grow area do I need for this system?
The footprint is flexible. At its most compact, the 20L pot version requires about 99" x 49". You can space the pots further apart for larger plants, extending the length up to 186". Please refer to the specifications table for detailed dimensions.
Do I need to buy a separate air pump?
The kit is available with or without an air pump. If you choose the option without, you will need to supply your own pump capable of at least 47.6 GPM (180 LPM) to ensure optimal oxygenation for all 18 pots.
Can I expand this system later?
Absolutely. The modular design is a key feature of all RDWC hydroponic systems from Alien. You can easily add more pots or rows as your operation grows. We also offer different sizes like the 12 Pot 3 Row kit if you need to start with a different configuration.
How do the Dual-Flow™ fittings help?
The patent-pending 2" Dual-Flow™ fittings are oversized and have special slots designed to prevent roots from blocking the pipes. This ensures your nutrient solution circulates freely and consistently, preventing clogs that can harm your plants.
