Change substrate of a stressed plant

[Dimples]

Yes, avoid getting the leaves wet. They will dry extremely slowly in the cloche/terrarium and that’s a recipe for bacterial or fungal problems.

If you have time to regularly water the aerial roots so the plant stays hydrated while it grows more roots into the pot over the next few weeks, it’s fine to leave it as it. If you don’t think you will be able to keep at it that long, I would be repotting it again and putting the aerial roots into the pot where they’ll stay moist longer. New bark holds very little water so the “air” roots will be happy enough in the pot. If they eventually start to fail from the change of conditions, the plant should have grown plenty of new roots by then.

Putting the pot on a seedling heat mat will speed root growth. I’ve noticed explosive root growth in my phals since adding a heat mat. The plants on display (not on a heat mat) are growing roots at a snail’s pace and the ones on the mat are putting out new roots and new tips on old roots so fast I can hardly believe it.
