Thanks everyone for your ideas. Turns out that she didn't just want the plants for decoration after all. She ended up throwing out two of them because they were males and would mess up the female's budding. So luckily we only have one left, and the house doesn't smell anymore. I still hate the thing though. My friend told me not to put any bleach in it because my roomate will probably smoke it after it dies, and we don't know what the bleach would do to her. I'll keep on with the salt and coke. So far it hasn't done a thing!
