The plants I have seen grown out in fogponics were at a hydro store. The baskets contained hydroton clay pebbles, and the fog kept creeping up out of the baskets, making algae grow in the top of the clay pebbles.
A pump that makes 35 psi or greater is the easiest way to do aeroponics. They come in different sizes and models. Smaller pumps run continuously and charge a tank, which gets periodically released with each cycle. Large pumps like a well pump just flip on and off with each cycle.
Good luck with your experiments.
