The new Alien® flood and drain hydroponic system consists of a new heavy-duty steel wall mounted control module. The module is microprocessor controlled so there are no moving parts inside making this the most reliable flood and drain system on the market today.
Alien 4 Pot Flood & Drain XL
Previous flood and drain systems have used ‘mechanical’ float switches which can be bulky, inaccurate, easily disabled by debris and their moving parts are often unreliable with disastrous results when they fail. To overcome the failings of a mechanical float switch we have designed an ‘Electronic Control Unit’ (patent pending) that uses probes to electronically control the level of nutrient solution in the brain pot. The ECU also houses a programmable timer allowing you to control the frequency of flood cycles.
