I've never tried growing anything in hanging planters. When I was an apartment dweller, I just had a few pots on my porch to plant a little bit. like maybe a tomato plant (they do well in pots), or some herbs. Even though I have the space now, I still prefer my herbs to be in pots near my kitchen side door. They seem to do better in pots, easier to keep them moist and much more convenient to snip some when I need to for dinner.
