We've been running one of those for about a year now, it works great.
It has the Italian herbs in it right now and it grows like crazy.
The seeds are in cups in a piece of foam and the solution trickles through.
It's not really aeroponic; the roots hang down into the solution like hydroponic. You top up the water once in awhile and add a couple nutrient tablets when it tells you.
