Yup the mounted ones survive well & good, air movement is the key
Sometimes people get too engrossed with the aspect of watering..forgetting the air movement..after all most of the orchids are epiphytes..they love the air! But if grown indoors, watering that takes time to dry and that crown that gets too wet, will invite rotting. If I have a good space to mount them I would go that way, but sadly space limitations..so potted they go.
