Alien Hydroponics RDWC 12 Pot System

Alien Hydroponics RDWC - 12 Pot 4 Row

Tired of hydroponic systems that promise big but underdeliver? The Alien Hydroponics RDWC 12 Pot 4 Row kit is engineered for serious growers seeking commercial-grade performance and explosive yields without the complexity. This system is a perfect solution for experienced home growers or boutique commercial operations ready to scale up production.

This professional recirculating deep water culture (RDWC) system creates the ultimate environment for plant growth by delivering a super-oxygenated nutrient solution directly to the root zone. This process accelerates development, shortens vegetative cycles, and produces significantly larger harvests. The intelligent design prevents common issues like root clogging and nutrient imbalance, ensuring your plants thrive. It's an ideal step up from smaller setups like the 8-pot RDWC system, offering greater capacity for larger projects.

Available with either 5-gallon or 9.5-gallon pots, the system offers flexible configurations to fit any grow space. Its tool-free, no-glue assembly means you can set it up quickly and focus on what matters most—cultivating healthy, high-yielding plants.

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

What is the main benefit of an RDWC system?+

The primary benefit is explosive growth rates. By constantly circulating highly oxygenated water, Recirculating Deep Water Culture (RDWC) provides plant roots with an ideal environment to absorb nutrients, leading to faster development and significantly larger yields compared to other methods.

Is this 12-pot system difficult to set up?+

No, the Alien Hydroponics RDWC system is designed for easy assembly. It features threaded fittings and snap-on pipes, requiring no glue or complex tools. This allows for a quick, straightforward setup and makes future adjustments or expansions simple.

Do I need to buy a separate air pump?+

You have the option to purchase the kit with a compatible air pump or use your own. If you choose the latter, ensure your pump can deliver at least 120 liters of air per minute to provide adequate oxygenation for all 12 pots.

How does the system help keep the nutrient solution cool?+

The pots and piping are made from a heat-reflective silver polymer. This material reflects radiant heat away from the system, helping to maintain a cooler and more stable nutrient solution temperature, which is crucial for preventing root diseases and ensuring optimal nutrient uptake.

Can I expand this system in the future?+

Absolutely. The modular design is a key feature of the Alien RDWC lineup. You can easily add more pots or reconfigure the layout to fit a new space or scale your operation. For even larger grows, you might consider the 16-pot 4-row system.
