Who This Is For
- You are scaling to a 22-pot layout because managing pH and EC across individual pots is becoming a full-time job.
- You are moving to an RDWC system because high nutrient waste and uneven growth in static pots hurt your profits.
What We Found
- The silver pots keep solution temps several degrees lower than black buckets, which prevents root rot in hot rooms.
- We noticed the 2-inch pipe diameter is the real hero here since it stops root masses from ever choking the flow.
- You can set this whole 22-pot rig up without a single wrench, which makes mid-season cleaning much less of a chore.
What Users Say
- Operators who switched to this RDWC say they shaved a full week off their vegetative cycle due to the oxygen levels.
- Large scale growers report they stopped chasing pH swings across individual pots once the header pot took over.

FAQs
What is the main advantage of an RDWC system?
RDWC (Recirculating Deep Water Culture) systems constantly circulate a highly-oxygenated nutrient solution, which promotes incredibly fast root development and leads to larger plants and higher yields compared to many other methods.
Is this system suitable for beginners?
While designed for professional results, the tool-free assembly and stable environment make it manageable for dedicated beginners. However, its large scale is best suited for serious hobbyists or commercial growers.
What is the difference between the 20L and 36L pot options?
The 36L pots provide more volume for larger root systems, which is ideal for growing bigger plants or longer-term crops. The 20L pots are more compact and suitable for smaller plants or quicker cycles.
Do I need to buy a separate air pump?
The system is available with or without a compatible air pump. If you choose the 'Without Air Pump' option, you must supply your own pump that meets the specifications listed in the manual to ensure proper oxygenation.
How does the Dual-Flow™ fitting help my plants?
These patent-pending 2-inch fittings are oversized and have special slots designed to prevent roots from growing into the pipes and causing clogs. This ensures the nutrient solution flows freely and consistently to every plant in the system.
Can I expand this system later?
Yes, modularity is a core feature of the Alien RDWC series. You can add more pots or reconfigure the layout to adapt to your evolving needs, though you may need to upgrade your water pump for very large expansions.
What kind of maintenance is required?
Regular maintenance includes monitoring and adjusting the pH and EC of the nutrient solution, keeping the water temperature between 64-68°F (18-20°C), and cleaning the system between crop cycles.
