Alien Hydroponics RDWC - 20 Pot 2 Row
Struggling to achieve professional hydroponic results at scale? The ALIEN RDWC 20 Pot 2 Row Kit is the solution, delivering commercial-grade recirculating deep water culture (RDWC) performance in a system designed to maximize growth and yields. This is an ideal setup for serious growers and commercial cultivators looking for an efficient, large-scale hydroponic solution that simplifies complexity.
This advanced RDWC hydroponic system provides an abundance of oxygen and circulates nutrient solution directly to the root zone, creating the perfect conditions for explosive growth and rapid development. The unique design from Alien Hydroponics prevents common issues like root clogging and oxygen deficiency that can limit your plants' potential. For growers needing a different capacity, similar high-performance kits are available, such as the 18 Pot 2 Row and 24 Pot 2 Row systems.
Choose between 5-gallon (20L) or 9.5-gallon (36L) pot sizes and configure the system with either compact or remote headers for flexible placement in any grow environment. The tool-free, no-glue assembly allows for quick setup and easy maintenance, making the transition to professional hydroponics straightforward for any experience level.

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
What makes the RDWC system different from a standard DWC?
A Recirculating Deep Water Culture (RDWC) system actively circulates the nutrient solution throughout all the pots. This keeps the pH, EC, and temperature consistent across the entire system, leading to more uniform growth. Standard DWC systems have static, individual reservoirs that can create inconsistencies between plants.
Is this 20-pot system suitable for beginners?
While the 20-pot system is designed for large-scale growing, its tool-free assembly and modular design make it accessible. However, beginners might feel more comfortable starting with a smaller system to learn the principles of hydroponics, such as the Alien Hydroponics RDWC 4 Pot kit.
What is the main benefit of the Dual-Flow™ fittings?
The patent-pending 2-inch Dual-Flow™ fittings are significantly larger than those in many other systems. Their unique slotted design allows water to flow freely while preventing roots from passing through and causing blockages, which ensures consistent nutrient delivery and reduces maintenance headaches.
Do I need to buy a separate air pump?
You have the option to purchase the kit with a powerful Air Pump 20, which is perfectly matched for this 20-pot system. If you choose the "Without Air Pump" option, you will need to supply your own pump capable of delivering at least 52.8 gallons (200 liters) of air per minute to ensure adequate oxygenation.
Can I expand or change the layout of this system later?
Absolutely. One of the key advantages of the Alien RDWC systems is their modularity. The snap-on pipes and threaded fittings allow you to easily reconfigure your layout, increase pot spacing, or add more pots to the system as your operation grows.
How does the heat-reflective material help my plants?
The system is constructed from a heat-reflective silver polymer. This material helps reflect radiant heat from grow lights and the environment, keeping the nutrient solution cooler. Maintaining an optimal root zone temperature (18-20°C or 64-68°F) is crucial for preventing root diseases and maximizing nutrient uptake.
