What are the main differences in aero and hydroponics I know aero is supposed to be really efficient (from a nutrients standpoint) but I would imagine hydro is very similar in this respect. What would be the pros and cons of each (I understand the basic concept just wondering why you would choose one over the other)? I am interested in making a small automated garden with one of these methods but would like to go the simplest route to make sure I don't fail and lose interest.
