We support operations & licensed facilities with volume pricing, dedicated account managers, and custom equipment consultation.
- You are looking to scale up your output because your current hand-watered trays cause too much nutrient variability.
- You are moving to a recirculating system because you need to reduce your manual workload and conserve your nutrient supply.
- The modular design allows you to adjust the layout and spacing if your grow room configuration changes.
- The 50mm dual-flow fittings provide a large enough path to keep nutrient delivery consistent without root clogging.
- Growers who transitioned to this recirculating system report that they no longer deal with inconsistent nutrient levels.
- Users who added the optional top-up tank found they could stop topping off their system by hand every single day.
Alien Hydroponics RDWC - 8 Pot 2 Row
Struggling to achieve professional hydroponic results without a complex, large-scale setup? The ALIEN RDWC 8 Pot 2 Row system delivers commercial-grade recirculating deep water culture (RDWC) performance in a compact, user-friendly package. It's engineered to maximize your growth potential by eliminating common hydroponic issues like root clogging and oxygen deficiency.
Perfect for intermediate growers and small-scale commercial operations, this system provides abundant, super-oxygenated nutrient solution directly to the root zone for explosive growth and impressive yields.

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 constantly circulate a super-oxygenated nutrient solution through the plant's root zone. This process dramatically increases nutrient uptake and promotes explosive root growth, leading to significantly faster vegetative cycles and larger yields compared to many other methods.
No, the Alien RDWC is designed for easy, tool-free assembly. It uses threaded fittings and snap-on pipes, eliminating the need for glue. This makes setup, breakdown, and reconfiguration straightforward for growers of any experience level.
The system is available with or without an air pump. If you choose the 'With Air Pump' option, a correctly sized pump is included. If you select 'Without Air Pump', you will need to provide your own pump capable of delivering at least 21.1 gallons (80 liters) of air per minute to power the JET-STREAM A.I.R.™ rings effectively.
The pots and piping are made from a heat-reflective silver polymer. This material helps to reflect radiant heat away from the system, keeping the nutrient solution within the optimal temperature range of 18-20°C (64-68°F) and preventing root health issues.
Yes, all Alien Hydroponics RDWC systems are modular. You can easily add more pots or reconfigure the layout to fit a larger space as your cultivation needs grow. This scalability makes it a great long-term investment.
The main difference is the oxygenation method. The RDWC uses JET-STREAM A.I.R.™ rings and an air pump to oxygenate the water. The Alien V-SYSTEM uses a venturi effect created by the water pump to draw air into the solution, eliminating the need for a separate air pump. Both are highly effective DWC hydroponics methods, but offer different approaches to achieving hyper-oxygenated water.
