Who This Is For
- You are switching to RDWC because manual feeding creates too many nutrient fluctuations in the root zone.
- You are moving to a modular system because fixed-length setups make it impossible to reach plants in the back row.
What We Found
- We noticed the 2-inch fittings allow for much faster drainage during reservoir changes than the smaller 1-inch sets.
- The silver polymer finish actually keeps nutrient temps a few degrees lower than standard black buckets in our tests.
- We suggest the remote header option if you want to check your nutrient levels without entering the actual grow area.
What Users Say
- Growers who switched from DIY systems say they finished the full 18-pot install in under an hour with no leaks.
- Users report they shortened their vegetative cycle by two weeks because the air rings drive fast root development.
- Facilities using these setups report they spend far less time on maintenance since the system recirculates on its own.
Alien Hydroponics RDWC - 18 Pot 2 Row
Tired of complex hydroponic setups that don't deliver professional results? The ALIEN RDWC 18 Pot 2 Row Kit is the solution, offering commercial-grade recirculating deep water culture (RDWC) performance in a system engineered for explosive growth and simplicity.
Designed for serious home growers and commercial cultivators, this 18-pot system from Alien Hydroponics provides an abundance of oxygen and nutrients directly to the root zone. This creates the ideal conditions for rapid development and helps prevent common issues like root clogging and oxygen deficiency that can limit your plant's potential. This modular design is also available in other configurations, like the 16 pot or 20 pot versions, to perfectly fit your space.
Choose between 5-gallon (20L) or 9.5-gallon (36L) pots and configure your header for flexible placement in any grow tent or room. The tool-free, no-glue assembly ensures a quick, hassle-free setup, making the transition to professional hydroponics straightforward for growers at 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 is the main advantage of an RDWC system?
A Recirculating Deep Water Culture (RDWC) system constantly circulates a super-oxygenated nutrient solution through the root zone. This leads to explosive root growth, faster vegetative cycles, and significantly larger yields compared to many other methods.
How does the Dual-Flow™ fitting help my plants?
The patent-pending 2-inch Dual-Flow™ fittings are designed to be much larger than standard fittings. This significantly reduces the chance of roots clogging the pipes, ensuring your plants receive a consistent and reliable flow of nutrients and oxygen at all times.
Is this system difficult to set up?
No, the Alien RDWC system is designed for easy, tool-free assembly. It uses threaded fittings and snap-on pipes, so no glue is required. This makes setup, reconfiguration, and maintenance much simpler than traditional systems.
What's the difference between the 20L and 36L pot options?
The 36L (9.5-gallon) pots provide more room for root development compared to the 20L (5-gallon) pots. This makes them ideal for growing larger plants or for longer growth cycles where a more extensive root mass is expected.
Do I need to buy a separate air pump?
You have the option to purchase the kit with a high-powered air pump included. If you choose the 'Without Air Pump' option, you will need to supply your own pump capable of delivering at least 47.6 gallons per minute (180 liters per minute) to ensure adequate oxygenation for all 18 pots.
How is this different from the Alien V-SYSTEM?
The main difference is the oxygenation method. The RDWC system uses JET-STREAM A.I.R.™ rings and an air pump to inject oxygen into the water. The Alien V-SYSTEM uses a venturi pump to create a vortex that draws air into the water, eliminating the need for a separate air pump.
