Live plant for a snake cage

[daddy and son]

Hi all, trying to do some learning and such before I get my snake. (it'll probably be late Sept. before we actually set it all up and put a live snake in the tank). Anyway, asking questions and learn. I want to put some live plants in the tank. I'm thinking philodendron. It will grow in just water, no dirt required. It will add oxygen and humidity to the tank, requires very little light (people grow them in offices with fluorescent lights all the time). They're a vine so will add to the decor. I just want to make sure they're not hazardous to a BRB. Thoughts on this? Thanks in advance. Michael
