Who This Is For
- You are scaling to a 32-pot setup because your current hand-watering routine is eating up every hour of your workday.
- You are moving to a recirculating system because inconsistent nutrient levels in static pots are stalling your growth.
What We Found
- The silver polymer actually keeps the solution several degrees cooler than standard black buckets in a warm room.
- The 2-inch fittings are the real star because they let roots grow thick without slowing down the system flow rate.
What Users Say
- Growers who switched from top-feed systems say they cut their veg time by a week due to the massive oxygenation.
- Users managing large rooms say the tool-free threaded fittings made their initial setup much faster than expected.
Alien Hydroponics RDWC - 32 Pot 4 Row
Are you looking to achieve professional, commercial-scale hydroponic results without the typical complexity? The Alien Hydroponics RDWC 32 Pot 4 Row system is engineered to deliver exceptional growth and massive yields, streamlining large-scale cultivation for licensed producers, research facilities, and serious growers.
This complete recirculating deep water culture system provides a constant flow of super-oxygenated, nutrient-rich solution directly to the root zone of 32 plants. This process eliminates the risk of stagnant water and oxygen deficiency, creating the perfect environment for explosive, healthy root development and significantly faster growth cycles. The entire Alien Hydroponics lineup is designed for performance, and this large-scale kit is a prime example. For growers with slightly different space requirements, models like the 28 Pot 4 Row system offer similar performance in a more compact footprint.
With a choice between 20L (5 gal) and 36L (9.5 gal) pots and a modular, tool-free assembly, you can customize the layout to perfectly fit your grow space. Say goodbye to root clogging and unstable nutrient levels—this system is built for consistency, efficiency, and incredible results.

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 the airline to the JET-STREAM A.I.R.™ rings in the pots.
4. Integrate Pumps
Install the water pump for recirculation and a chiller pump if applicable.
5. Fill the System
Add water and your nutrient solution to the header pot.
6. Plant Your Crop
Place your plants in the net pots with your chosen substrate and begin growing.
Maintenance Tips:
- Maintain water temperature between 18-20°C (64-68°F) for optimal root health.
- Always add nutrients to the system and allow them to fully circulate before testing and adjusting pH/EC.
- Regularly check and clean the system filters to ensure unobstructed flow.
- Use preventative solutions to maintain root health and overall system cleanliness.

FAQs
What is the main advantage of an RDWC system?
A Recirculating Deep Water Culture (RDWC) system constantly circulates the nutrient solution throughout all the pots. This ensures a uniform distribution of nutrients, stable pH and EC levels, and consistently high dissolved oxygen, which are critical for maximizing growth in DWC hydroponics and preventing issues common in static systems.
Is the 32-pot system suitable for a beginner?
This 32-pot system is designed for commercial-scale operations or very experienced growers due to its size and capacity. While the system itself is user-friendly, managing 32 large plants requires significant experience. Beginners may want to start with a smaller kit, such as the Alien RDWC 4 Pot 2 Row, to familiarize themselves with the technique.
Can I expand this system later?
Yes, all Alien Hydroponics systems are modular. You can add more pots or reconfigure the layout by purchasing additional components, allowing the system to scale with your operation's needs.
What is the difference between the 20L and 36L pot options?
The primary difference is the volume available for root development. The larger 36L (9.5 gal) pots can support much larger plants with more extensive root systems, potentially leading to higher yields. The 20L (5 gal) pots are more compact and suitable for smaller plant varieties or when space is a constraint.
Do I need to buy an air pump separately?
The system is available with or without an air pump. You can choose the kit that includes the high-powered Air Pump 40, or you can opt to use your own, provided it meets the minimum requirement of delivering 84.5 gallons of air per minute to adequately oxygenate all 32 pots.
