Is there a guideline for GPH per square foot of growing area? It will be sort of an aeroponics system.

A lot of submersible pumps contain oil and are not "food" safe. Fish are very susceptible to chemicals, so pond pumps are a little less risky when used in hydro and they're either magnetic or direct driveI don't understand. A pump pumps water. What distinguishes a hydro pump from the rest? Submersible? Size?
I fail to see why a non-submersible pump system wouldn't work.
Please explain.
Your only requirement for hydro is to wet the roots and let them dry. Aeroaponics will require enough pressure and volume to bust the water into tiny droplets
