Hey, don't worry. Phals aren't all that difficult. Just give them a medium that won't suffocate the roots. I grow mine in lava rock, clay pots, and this gives the roots the air they need. Bark with a net pot would also be great. Your household conditions sound perfect. They like bright but not direct light and, yes, don't get water on the leaves or in the crown. If you do, just dry them with tissue or use a fan to dry them. Good luck!
