Phal light, don't let it get too dry in between waterings, choose a media that works in your conditions and with your watering habits (for me, that's a bit finer graded bark/sphagnum/perlite). I would guess intermediate to warm temperatures should suit it well.
I guess it's not your first Paph, or?
Good luck and congrats on what looks like a very nice Maudiae hybrid!
