it is looks lovely
dont mist too much
maybe-and just because you live in a dry place
put the pot in a plate full of toof stones with water - so the pot will be on the toof but not in the water at all-this helps to kip the humidity around the orchid all the time - and than 2-3 times a day u can mist
enjoy your new orchid-it is a beutifull rooting systeam
