Who This Is For
- Growers scaling from hand watered buckets who struggle with manual nutrient mixing and root zone oxygen levels.
- Cultivators working in compact grow areas that require a flexible, modular layout to maximize floor space.
What We Found
- The oversized 2 inch fittings stop root mass from choking the nutrient return lines during late stage development.
- We tell growers the silver polymer construction is essential because it keeps nutrient solution temperatures stable.
What Users Say
- Operators who switched to this recirculating system report they no longer see root browning from oxygen deficiency.
- Users who previously dealt with clogged return pipes say the 2 inch fittings cut their maintenance time significantly.
Alien Hydroponics RDWC - 4 Pot 1 Row
Tired of complex hydroponic setups that don't deliver professional results? The Alien Hydroponics RDWC 4 Pot 1 Row Kit is the solution, offering commercial-grade recirculating deep water culture (RDWC) performance in a compact, user-friendly system. It's engineered to maximize growth, delivering highly oxygenated nutrients directly to the root zone for explosive development and impressive yields.
Perfect for intermediate growers or home cultivators seeking to elevate their harvest, this professional-grade RDWC hydroponic system prevents common issues like root clogging and oxygen deficiency. Choose between 5-gallon or 9.5-gallon pots to suit your plants' needs. The tool-free, no-glue assembly makes setup a breeze, allowing you to focus on what matters most—your plants. If your space allows for a different layout, explore other configurations from Alien Hydroponics, such as the 6-pot version or the larger 8-pot, two-row kit.

- Connect the System: Use the provided piping to connect the pots and the header pot, establishing the recirculating network.
- Install Air System: Set up the air pump and connect it to the air injection rings in the pots.
- Integrate Pumps: Install the water pump for recirculation.
- Fill the System: Add water and nutrients to the system and check for leaks.
Maintenance Tips:
- Maintain water temperature between 64-68°F (18-20°C).
- Always add nutrients to the system and allow for full recirculation before testing and adjusting pH/EC levels.
- When planting, use a substrate layer in the net pot, water the cutting, then fill the remaining space with your chosen medium.
- Use preventative solutions like root stimulants to maintain root health and overall system cleanliness.

FAQs
What is the main advantage of an RDWC system?
Recirculating Deep Water Culture (RDWC) provides a constant flow of highly oxygenated, nutrient-rich water directly to the plant's roots. This encourages explosive root growth, faster vegetative cycles, and ultimately, larger yields compared to static DWC hydroponics or soil-based growing.
How difficult is this system to set up?
The Alien RDWC is designed for easy, tool-free assembly. It uses threaded fittings and snap-on pipes, so no gluing is required. Most growers can have the system set up and ready to go in under an hour by following the included instructions.
What is the difference between the 20L and 36L pot options?
The primary difference is the volume available for root development. The 36L (9.5-gallon) pots are ideal for larger plants or longer growth cycles, as they provide more space for an extensive root mass. The 20L (5-gallon) pots are great for smaller plants or growers working in more compact spaces.
Can I expand this system later on?
Absolutely. The modular design is a key feature. You can easily add more pots or reconfigure the layout to fit a new space. As your needs grow, you can expand your setup or upgrade to a larger system like the Alien Hydroponics RDWC 12 Pot 2 Row kit.
Do I need to buy a separate air pump?
The system is available with or without an air pump. If you choose the option without, you must supply your own air pump capable of delivering at least 10.6 gallons (40 liters) of air per minute to ensure adequate oxygenation for the JET-STREAM A.I.R.™ rings.
