Who This Is For
- You are switching to RDWC because your current top-feed system leaves stagnant pockets that invite root pathogens.
- You are installing a modular system because your room layout changes and fixed plumbing makes maintenance difficult.
- You are moving to oversized fittings because root mass in smaller systems keeps clogging your return lines.
What We Found
- The 2-inch fittings are a massive upgrade because they prevent the root clogs we see in standard 1-inch systems.
- We noticed the silver pots keep nutrient temperatures several degrees lower than the standard black plastic versions.
- The threaded connections are much more reliable than friction-fit systems that tend to weep at the joints over time.
What Users Say
- Growers who switched to this modular system say they stopped worrying about leaks after using the threaded fittings.
- Users who upgraded from 1-inch systems say they stopped losing plants to clogged drains during peak growth phases.
- Buyers who moved away from manual reservoirs say the recirculating flow keeps their nutrient levels much more stable.

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?
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.
Is this system difficult to set up?
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.
Do I need to buy an air pump separately?
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.
How does this system keep the nutrient solution cool?
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.
Can I expand this 8-pot system later?
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.
What's the difference between the RDWC and the V-SYSTEM?
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.
