DWC is NO form of aeroponics. Aeroponics is a completely different and actually, very opposite of DWC.

DWC is oxygenating a full time nute bath via an air pump and stone. Aero on the other hand is using high pressure to spray nutrient through a sprayer at such a fine mist that it oxygenates the nutrient and sprays the roots, while the roots remain suspended in air.

Aeroponics actually is extremely efficient, however high maintenance and susceptible to power failure. DWC is again the opposite of that.
