Thanks for the add. :)
I just used an old olive jar I cleaned out well with vinegar and rinsed well.. then filled it with gravel and added a root tab for the potted plant...I don't know how well it would do long term though..I plan on moving that plant into my 10 gallon eventually..I just didn't have a deep enough root base at the moment for it in my 3 gallon..
