It is definitely hard to find solid info, especially on Aero. Check out the thread called "uc vs aeroponics". This is one of the best threads I have found on Aero, and it also includes a link to another really great thread on another forum.
I would just absorb as much info as possible, take nothing as gospel until you see hard science behind it and don't be afraid to try things yourself and draw your own conclusions. These I believe are important concepts for any system of growing.
Personally I have read about everything I have been able to find on Aero, some of it twice, three or four times. I believe the best way to go is to use a pressure/accumulator tank, filled with nutrients and pumped to pressure (100psi+) using a manual hydrostatic testing pump, and using a solenoid valve hooked to a cycle timer hooked to a battery, so that power outtages are a non-issue, pump failures are a non-issue and the all-around simplicity of it is beautiful, not to mention the cost effectiveness. This is just the best method I have found, and credit goes to John Guest in the "uc vs aeroponics" thread as I certainly am no expert and do not claim to be one.
Google is your friend, but I will tell you right now if you don't like getting into technical details, and have no patience for attention to detail, I would definitely go another route. Also I'm not sure of your growing experience, but it is important to understand your plants, how to work with them and what their needs are, as well as some concepts in water chemistry, PH, alkalinity vs alkaline/acidic, nutrient antagonism, NPK ratios, the works.
I hope you really like to read! :) Best of luck to you.
