NOID Antelope Type Dendrobium Repot While Flowering
 

All the advice says to repot when new root growth starts, but it also says not to repot when in flower. I have both happening.

My new Den is in a 4" pot, but has a 12" root spread. It has climbed so far out of the pot it is basically bare root, and I am needing to water twice a day to keep her happy. She is in full bloom. She is a little sensitive to changes and has already lost 4 leaves and 2 buds blasted to what seems to be stress, as there are no other symptoms. So I don't want to stress her, but am unsure what is going to be less stressful for her.
Photos are
1) fully open flowers
2) new growth starting on roots
3) whole plant with roots the day I got her (Dec 16).
Should I try to repot her, or wait?

The flowers are beautiful!

Put the whole thing, including pot, into another pot big enough to hold it, about 2-3 inches/5-7.5 cm larger in diameter. Backfill with the medium of your choice. This is a magic Dendrobium growing technique.

So the old pot kinda becomes "inorganic media"? That makes sense. Should I be planning on removing both pots the next time I repot, or is this pot kinda part of the plant now?

A lot of people keep repotting this way indefinitely.

Awesome! Thank you so much estación seca.
