I mist my inside orchids twice a day, even the Phals. If you are afraid of crown rot, spray the very center with alcohol...it will dry up the water, in the very center. Close to the inside orchids, I keep an ordinary (cheap )small spray bottle for alcohol and another larger one for water. If you do get crown rot, carefully cut the rotten part off, spray the cut with alcohol, and then dust with plant sulphur powder. Works for me & my orchids! Betty :-)
