I mostly use pothos, but I've see boston fern in Mark's enclosures, and clumps of some kind of grass that they like to hide under. You put the plants in there with the mind set that they're not going to live long, so you have duplicates growing elsewhere that you can change out when the first set needs to come out.The bulbs are the ceramic heating bulbs. I can. What plants would tolerate the dim light and humidity?
