Being the inventor of the culture technique for orchids, over time, I have moved pretty much all of my tropical houseplants into S/H culture, as well, but I have modified the approach slightly.
Some of the plants are in the "Leni" or Luwassa", 3-component hydro pots (solid outer pot that creates the reservoir, mesh culture pot that contains the LECA and plant, and a float gauge that keeps you apprised of the water depth in the reservoir), except I have removed the gauge, replacing it with a "watering globe". I have also converted other decorative outer pots to this by merely hot-gluing a piece of PVC pipe to the inner wall before filling with medium. I have also drilled a single 1/4" hole just above my maximum water line, so I can occasionally put the pots in the sink and just run water through them for flushing.
Not only is the watering globe a good visual indicator of the need to water, it extends the time frame between waterings significantly!
