Stanhopea wardii and sophrontis cernua?

[rainbuilder]

How hard is it to grow stanhopea wardii/sophrontis cernua? I would like to use them for a project (mount type thing) I'm doing, and was wondering if they could handle average household conditions. I do have very strong daylight bulbs in the room it will be in and there is also quite a bit of natural sunlight as well. I can mist it and water them or whatever as needed, but I was kind of worried about the humidity. While I'm at it, do any of you know of a good epiphytic moss that would grow in these conditions as well to kind of fill in blank spaces and allow for more moisture retention.
