If you put live plants in the enclosure, don't you need to keep a lamp/have UVB in there for the photo period? Even if a room has windows, is it really enough ambient light? What if its north facing? Doesn't get any direct sunlight? Has another house or tree or obstruction in the way?
There are tons of houseplants that don't need direct sunlight to thrive. Most types of philodendron and hosta are two I can think of off the top of my head, mostly because I have them, My philo lived 3 years a few feet away from a north facing window and did just fine.
