I have been contemplating to set up a small vertical hydroponic system, but I am struggling a bit to come up with plants I would actually like to eat that would fit well.

Stuff like tomatoes or pepper just seems to grow way too big to function well in a typical vertical setup, and I am not a big fan of leafy salads to eat.

I found a nice small cabbage (Japanese Tatsoi), which is quite ok, but other suggestions would be welcome.
