FAQs
Recirculating Deep Water Culture (RDWC) provides a constant flow of highly oxygenated nutrient solution to the plant's roots. This leads to explosive root growth, faster vegetative cycles, and significantly larger yields compared to traditional soil or other hydroponic methods.
The Alien RDWC is designed for simplicity. With tool-free, glue-free assembly, it's straightforward to set up. While it's a professional-grade system, it's an excellent choice for intermediate growers or ambitious beginners ready to step up their cultivation game. For those looking for other types of automated systems, we also carry a range of ebb and flow systems.
Both are high-performance systems. The RDWC uses JET-STREAM A.I.R.™ rings for oxygenation, while the Alien V-SYSTEM uses a venturi pump that draws air in without needing a separate air pump. The V-SYSTEM also features larger 5" piping and a unique vortex fluid motion.
The 36L (9.5-gallon) pots provide more room for root mass development compared to the 20L (5-gallon) pots. This makes them ideal for growing larger plants or for longer growth cycles where an extensive root system is beneficial for maximizing yield.
Absolutely. The modular design of the Alien RDWC system allows for easy expansion. You can add more pots to your setup as your cultivation needs grow, making it a scalable and long-term investment.
You have the option to purchase the kit with or without an air pump. If you choose the 'Without Air Pump' option, you will need to supply your own pump capable of delivering at least 21.1 gallons per minute (80 liters per minute) to properly oxygenate the system.
