You can also use clay balls. I think you can buy those at walmart. Using dirt without drainage holes is a recipe for disaster. Even if you only add a little water at a time, it still pools at the bottom and will inevitably rot the roots.
I did a Dieffenbachia (a.k.a. Dumb Cane) hydroponically, and it was quite beautiful. I just used pea gravel as the media in a small mason jar. I think it's way nicer looking than potting soil.
