brit, someonenew was right. aeroponics are more advance form of hydroponics. and you are right with regards to it's mechanism. BTW, are nutrients from the soil of food grade quality? I ask this because we are made into thinking since we were small kids that soil is dirty. Kidding aside, depending on its origin, the soil always contain mostly heavy metals (aluminum, mercury, arsenic, cadmium, lead) from traces to significant amounts. Hence, soil culture and organic culture (since you also grow plants in soil practically) are not as 'clean' as those plants grown in hydroponics.
