Who This Is For
- You are shifting to high-pressure misting because your current media-based setup creates too much waste and mess.
- You are scaling up to 21 pots because manual nutrient delivery has become a bottleneck for your daily workflow.
- You are moving to aeroponics because you want the explosive growth of RDWC without the stability risks of warm water.
What We Found
- The silver piping stays cool to the touch even under high intensity lights where black tubing usually gets soft.
- The snap-on design makes mid-season deep cleans much easier since you aren't fighting glued joints or stuck PVC.
What Users Say
- Users who switched from flood-and-drain say they stopped hauling hundreds of gallons of water every week.
- Operators using high-pressure mist report they shaved a full week off their vegetative growth cycle.
Alien Hydroponics AERO System - 21 Pot 3 Row
Tired of hydroponic systems that promise big but under-deliver? Unlock professional-grade results with the Alien Hydroponics AERO System - 21 Pot 3 Row Kit, an advanced aeroponic solution designed for serious growers. This system directly addresses common issues like poor oxygenation and nutrient uptake by delivering a super-oxygenated, high-pressure mist to the root zone, promoting explosive growth and significantly larger yields while using up to 95% less water than traditional methods.
Built for efficiency and scalability, this 21-pot kit is perfect for large operations and can be expanded up to 36 pots. The innovative design features patent-pending Dual-Flow™ fittings to prevent root clogging and heat-reflective pipes to keep your nutrient solution cool and stable. Unlike some RDWC systems, the AERO system offers a soil-free environment that maximizes nutrient absorption for healthier, faster-growing plants. Assembly is straightforward with a no-glue, snap-on design, making setup and maintenance easier than ever.
Please note: A nutrient reservoir is required for operation but is not included with the kit. We recommend pairing this system with a compatible reservoir, such as the 70 Gallon Alien GardenTank, to ensure optimal performance.

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 a 50-75cm center distance between each pot.
- Alien Hydro recommends a watering frequency of one minute every hour.

FAQs
The primary advantage of aeroponics is the superior oxygenation of the root zone. The AERO system continuously mists roots with a highly-oxygenated nutrient solution, which can lead to faster growth rates and larger yields compared to Deep Water Culture (DWC) systems where roots are submerged. Explore our full range of Alien Hydroponics systems to see which method best suits your goals.
For a 21-pot system, we recommend a reservoir with a minimum capacity of 70 gallons (280 liters). This ensures you have enough solution to run the system effectively without needing constant refills. The Alien GardenTank - 70 Gallon Reservoir is an excellent, purpose-built choice for this kit.
No, the Alien AERO system is designed for easy assembly. It features threaded fittings and snap-on pipes that do not require any glue. This makes setup, reconfiguration, and cleaning much simpler than many other large-scale hydroponic systems.
While possible, it's generally recommended to use mineral-based (synthetic) nutrients with aeroponic systems. Organic nutrients can be thicker and may contain particulates that can clog the fine sprinkler heads, disrupting nutrient delivery. Using mineral-based nutrients ensures minimal cleaning and consistent operation.
We recommend a full system flush and clean between each crop cycle. During the cycle, regularly check the main filter for any debris. The copper-plated drain covers and Dual-Flow™ fittings are designed to minimize blockages, reducing the need for frequent maintenance.
Yes, the Alien AERO system is fully modular and designed for scalability. You can purchase additional pots and fittings to expand your setup as your operation grows. Alien offers many configurations, including the larger 24 Pot 3 Row AERO system.
