Commercial & Bulk Purchasing
We support operations & licensed facilities with volume pricing, dedicated account managers, and custom equipment consultation.
Who This Is For
- You are scaling your facility because managing individual reservoir levels across 36 pots is a full-time job.
- You are moving to RDWC because your current drip setup keeps clogging and slowing down your vegetative cycles.
- You are choosing this modular kit because you need a layout that can be reconfigured without cutting or gluing pipes.
What We Found
- The oversized 2-inch fittings are the real winner here since they almost never clog even with massive root masses.
- We found the tool-free threaded fittings make mid-season adjustments much easier than traditional friction fits.
What Users Say
- Growers who switched to this system say they stopped checking pH in every pot once they saw the total EC stability.
- Operators who scaled to 36 pots say the header pot makes feeding the entire room a five-minute job instead of hours.
Alien Hydroponics RDWC - 36 Pot 4 Row
Struggling to achieve commercial-scale hydroponic results without the complexity of traditional setups? The Alien Hydroponics RDWC 36 Pot 4 Row Kit is engineered for large-scale growers, licensed producers, and research facilities who demand industrial performance with streamlined management. This system delivers a hyper-oxygenated nutrient solution directly to the root zone, creating the perfect environment for explosive growth and significantly higher yields.
This advanced design overcomes common hydroponic issues like root clogging and oxygen deficiency that can hinder plant development. As one of the most comprehensive RDWC hydroponic systems available, it ensures uniform pH and EC stability across all 36 pots for consistent nutrient uptake. The tool-free, no-glue assembly makes setup and maintenance remarkably simple, allowing you to focus on cultivation. For growers looking for alternative high-performance irrigation, the Alien Hydroponics RAIN System offers a similar commercial footprint with drip-style delivery.

Setup and Maintenance
System Setup Steps:
- Prepare Pots: Attach the necessary fittings to the pots.
- Connect the System: Use piping to connect the pots and the header pot to establish the recirculating network.
- Install Air System: Set up the air pump and connect it to the air stones in the pots.
- Integrate Pumps: Install the water pump(s) for recirculation and chilling.
- Set Up Nutrient Tank: Connect the nutrient tank to the system.
- 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.
- 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
A Recirculating Deep Water Culture (RDWC) system constantly circulates a highly oxygenated nutrient solution through the plant's root zone. This leads to explosive root growth, faster vegetative cycles, and ultimately, larger yields compared to many other methods.
This system is designed for commercial-scale operations. While assembly is straightforward, managing 36 plants requires experience. Beginners may want to start with a smaller setup, such as the Alien Hydroponics RDWC 8 Pot system, to learn the technique.
The 36L (9.5-gallon) pots provide more space for root development, supporting larger plants and higher yields. The 20L (5-gallon) pots are more compact. The choice depends on your space and target plant size.
The system is available with or without an air pump. If you choose the 'Without Air Pump' option, you must supply your own pump capable of delivering at least 95.1 gallons (360 liters) of air per minute for all 36 pots.
The patent-pending Dual-Flow™ fittings feature an oversized 2-inch diameter and unique slots much larger than traditional fittings. This allows roots to pass through without causing blockages, ensuring consistent nutrient solution flow.
