Who This Is For
- You are moving to a 15 pot system because managing separate reservoirs by hand leads to uneven feeding and pH swings.
- You are upgrading to RDWC because your current passive DWC setup lacks the oxygenation needed to accelerate growth.
- You are choosing a modular system because your room layout changes and you need the flexibility to rearrange rows.
What We Found
- The 2-inch piping is the real hero here because it is significantly harder to clog than standard 1-inch lines.
- The silver lids do a better job than expected at reflecting light to keep the root zone naturally cooler.
What Users Say
- Growers who switched to this system say they shortened their vegetative cycle by over a week.
- Buyers report that the modular design made it easy to rearrange the layout when they moved to a larger room.
Alien Hydroponics RDWC - 15 Pot 3 Row
Struggling to achieve consistent, large-scale hydroponic yields without the operational headaches? The Alien Hydroponics RDWC 15 Pot 3 Row system is engineered to solve that exact problem, delivering commercial-grade performance with simplified management for serious home growers and boutique operations.
This advanced recirculating deep water culture system creates the ultimate environment for explosive growth. By constantly circulating a super-oxygenated nutrient solution directly to the root zone, it dramatically reduces vegetative time and boosts final yields. The unique design from Alien Hydroponics prevents common issues like root clogging and poor aeration that can hinder plant development. With a modular design and options for expansion, it's a versatile foundation for any serious grow room, with other configurations like the 18 Pot 3 Row system available for even larger setups.

💰
Efficient & Cost-Effective
Recirculating solution and minimal medium requirements reduce setup and operational costs.
🌿
Custom Configurations
Choose from multiple pot sizes and header types to perfectly tailor the system to your space.
Setup and Maintenance
System Setup Steps:
1. Prepare Pots
Attach the necessary Dual-Flow™ fittings to each pot.
2. Connect System
Use the provided piping to connect the pots and header, establishing the recirculating network.
3. Install Air System
Set up the air pump and connect it to the JET-STREAM A.I.R.™ rings in the pots.
4. Integrate Water Pump
Install the main water pump to begin recirculation.
Maintenance Tips:
- Maintain water temperature between 18-20°C (64-68°F) for optimal root health.
- Always add nutrients and allow the system to circulate fully before testing and adjusting pH/EC levels.
- When planting, use a light substrate layer, place the cutting, and fill the remaining space gently.
- Drain the system as needed using the designated valve and pipe fitting.
- Use preventative solutions to maintain root health and overall system cleanliness.

FAQs
What is the main benefit of an RDWC system?
Recirculating Deep Water Culture (RDWC) systems provide a constant flow of highly oxygenated nutrient solution directly to the plant's roots. This leads to explosive root growth, faster vegetative cycles, and significantly larger yields compared to many other methods.
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 gluing is required. You can follow the included user manual for step-by-step instructions.
What's the difference between the 20L and 36L pot options?
The main difference is the volume. The 36L pots hold more water and are better suited for growing larger plants that require more root space. The 20L pots are more compact and ideal for smaller plants or spaces where footprint is a concern.
Can I expand this system later?
Absolutely. The modular design is a key feature of all Alien Hydroponics RDWC systems. You can easily add more pots or reconfigure the layout to fit a new space as your operation grows.
How does the RDWC system compare to the Alien V-SYSTEM?
Both are excellent systems. The RDWC uses JET-STREAM A.I.R.™ rings and an air pump for oxygenation, while the V-SYSTEM uses a venturi effect that requires no air pump. The V-SYSTEM also features a vortex motion in the header pot to maximize nutrient mixing. The best choice depends on your specific growing style and preferences.
Do I need to buy a separate air pump?
You have the option to purchase the kit with a compatible, high-output air pump or without one. If you choose the "without" option, you must supply your own air pump that meets the minimum requirement of 150 liters per minute to ensure adequate oxygenation for all 15 pots.
