Who This Is For
- You are scaling to a 28-pot layout because managing individual reservoirs at this volume is a massive labor sink.
- You are switching to silver-clad piping because your current black lines absorb too much heat and cook your roots.
- You are investing in a modular system because fixed-pipe setups make it impossible to rearrange your floor layout.
What We Found
- The high-pressure air injection rings create more root-zone bubbles than the standard stones we used to sell.
- We noticed the silver polymer finish actually keeps the water several degrees cooler compared to standard black pots.
- Assembly is much faster than you expect since the threaded nuts and washers create a tight seal without any tools.
What Users Say
- Operators switching to this RDWC say the constant recirculation helped them harvest more biomass with less upkeep.
- Users managing multiple rooms report the modular pots make it easy to reconfigure layouts for different crops.
- Buyers tell us the super-oxygenated roots led to faster vegetative growth and shorter overall cycle times.
Alien Hydroponics RDWC - 28 Pot 4 Row
Struggling to achieve commercial-grade hydroponic results without the complexity of industrial systems? The Alien Hydroponics RDWC 28 Pot 4 Row is your solution, delivering the power of a professional recirculating deep water culture (RDWC) system engineered for maximum growth and operational efficiency. If your space requires a different configuration, we also offer the Alien Hydroponics RDWC 14 Pot 2 Row for more compact layouts or aeroponic alternatives for high-performance growing.
Designed for large-scale commercial growers, licensed producers, and research facilities, this 28-pot system provides an abundance of super-oxygenated nutrient solution directly to the root zone. This creates the ideal conditions for explosive growth, healthier plants, and significantly higher yields. The unique design actively prevents common issues like root clogging and oxygen deficiency that can limit plant development in other DWC systems.
Customize your setup by choosing between 5-gallon (20L) or 9.5-gallon (36L) pots and configuring the header for flexible placement in any grow environment. With a completely tool-free and glue-free assembly, transitioning to professional hydroponics has never been more straightforward.

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
The primary advantage is the massive amount of oxygen delivered to the plant roots. The constantly recirculating, super-oxygenated water promotes extremely rapid root growth, leading to healthier plants and significantly larger yields.
This system is designed for commercial operations. While assembly is straightforward, beginners may prefer a more compact kit, such as the Alien Hydroponics RDWC 4 Pot 2 Row, to master the technique before scaling up.
The 36L (9.5-gallon) pots hold a larger volume of water and provide more space for root development, making them ideal for growing larger plants and maintaining more stable pH and temperature levels.
The patent-pending Dual-Flow™ fittings are oversized to 2 inches and feature unique slots instead of simple holes. This design allows roots to pass through without blocking the flow of water.
You have the option to purchase the kit with a matched air pump. If you choose the option without one, you must supply a pump capable of delivering at least 74 GPM (280 LPM) to properly oxygenate all 28 pots.
