Mossy, I grow it along with all of my other paphs in a North East facing window and high humidity. I heard that they prefer warmer temperatures but this winter the temps range from a low of 58 to a high of 68 on the windowsill. The only difference from my other paphs is the potting mix. I usually use Orchiata, perlite, and charcoal, but on this one I use just medium Orchiata bark layered with sphagnum moss. As soon as the moss gets dry I water it instead of on a regular schedule and have only used fertilizer once a month. It has grown at pretty much the same rate (maybe a little faster) as the others even though it's roots were in rough shape when I got it.
