im running a DWC with a fogger setup right now... from what i can tell it is definately helping more than it is hurting anything. its really good for initial root development. and i have heard something about the diff. parts of the roots look for and absorb different things. and the part of the root mass that is usually not submerged supposedly seeks and absorbs nutes... if this is true, then the fogger should be crazy beneficial. just be sure to watch rez. temperature and pH as the fogger will increase both steadily...
