Choose the Right Alien Hydroponics System
Alien produces several distinct hydroponic systems, each designed around a different method of delivering water, nutrients and oxygen to the root zone.
Alien RDWC and RDWC PRO Systems
Alien RDWC systems continuously circulate an oxygenated nutrient solution between the individual growing modules and the central header. This helps maintain consistent pH, EC and nutrient availability throughout the system.
Choose from 20L and 36L RDWC PRO Silver systems, alongside larger configurations for more demanding installations. Wide circulation pipework, modular layouts and accessible components help simplify installation, cleaning and future expansion.
Alien V-System
The Alien V-System is the flagship option for growers seeking an exceptionally large root zone. Its 58L V-Pots, wide 5-inch circulation pipework and vortex water movement are designed to circulate and oxygenate the nutrient solution throughout each module.
Venturi technology draws air into the moving solution, removing the need for conventional air stones. The system’s sloped pot bases also support more complete drainage during nutrient changes and system cleaning.
Alien AERO Systems
Alien AERO is an active aeroponic system that suspends the roots inside the growing module and sprays them with nutrient solution. This provides direct control over feeding while allowing the roots to access high levels of oxygen.
Our range includes AERO Black and heat-reflective AERO Silver systems. These are best suited to experienced growers who are comfortable managing feed schedules, pumps, nutrient strength and root-zone conditions.
Alien EasyFeed Systems
Alien EasyFeed provides a simpler approach to automatic watering. The gravity-fed system bottom-feeds breathable fabric pots without requiring a water pump, while its battery-operated timer allows watering frequency and dry-back periods to be controlled.
EasyFeed systems are available with 10L, 16L, 22L and 30L pot options. Their modular construction makes them suitable for small installations as well as larger multi-pot layouts. Check the individual product contents, as a suitable water tank may need to be purchased separately.

Alien Hydroponics FAQs
Which Alien system is best for beginners?
EasyFeed is usually the most accessible option because it is gravity-fed and does not require a water pump. RDWC and AERO systems require closer management of the nutrient solution and root-zone conditions.
What is the difference between Alien RDWC and AERO?
RDWC keeps the roots in a continuously circulating and oxygenated nutrient solution. AERO suspends the roots in the growing module and sprays them at controlled intervals.
Does the Alien V-System require air stones?
No. The V-System uses vortex water movement and Venturi technology to draw oxygen into the nutrient solution without conventional air stones.
Can Alien Hydroponics systems be expanded?
Many Alien systems are modular and can be reconfigured or expanded with compatible modules, pipework and fittings. Always confirm compatibility with the exact system model before adding components.
