Hey Dan! Haven't seen ya in a while.
Can't advise you on the paphs or phrags -- I can't grow them no matter what I do. They all up and die on me.
Unless you can do some supplemental lighting, I think you'll have to skip the catt and onc alliances. They tend to need quite a bit more light than you're looking at -- though just how "intermediate" we're talking here could make all the difference.
Onc. Mendenhall -- now known as Psychopsis (unless those darned taxonomists have made yet another change) will handle Phal light conditions as I recall.
Are you living on campus still or off? Masdies might be an option but not if you're still in the dorms -- the heat and the dryness would kill them off. Other members of the Pleurothallid alliance might also be options. If you were into mini's and wanted to and could do a terr that would also give you some options.
