Just normal Paph culture—indoors under lights with air movement and a temperature drop at night. It grew for more than two years and formed multiple growths before it decided to bloom.
They had pics on their website showing similar coloring. I agree the result is surprising given the album form of fowliei is used. This is its second blooming. The first time it bloomed for me the petals were not so nicely presented.
They didn’t seem to care (or know)—there wasn’t a policy about it in place. This was 35 years ago. If in doubt you could inquire. Most dorms have pet restrictions of some kind but I have not heard of plant restrictions. I wouldn’t imagine it being a problem having just a few unless you are...
I had a few in my dorm room. I packed them in my luggage and took them home for winter break. There was a utility closet with a sink just across the hall where they got watered.
