Can and when should you water an orchid with hollow rotten roots after trimming the roots, drying them, repotting and changing the potting medium?

Today a fellow orchid grower asked a question: for an orchid with hollow rotten roots, after trimming the roots and drying them, then repotting and changing the potting medium, can you water it once it is potted? When should you water?

What the grower asked about is watering after treating an orchid with hollow roots. First, you have to know how hollow-root orchids form. Good Shot Farmer has said before that hollow-root orchids are mostly caused by the potting medium being too dry for a long time. Unlike rotten roots, hollow-root orchids are relatively easy to save, but you still need to pay attention when watering after potting.

Good Shot Farmer suggests that when repotting a hollow-root orchid, you must trim away all the hollow roots cleanly, otherwise these hollow roots will rot and cause infection of the other orchid roots. After trimming, just let the hollow-root orchid dry in the shade for half a day; unlike rotten-root seedlings, it does not need the roots and pseudobulbs sun-dried. The potting medium should not be too wet; it is enough if it feels slightly moist to the touch. After potting, place it in a cool, ventilated spot to acclimate for two nights, then water lightly, and only after ten consecutive days resume normal care.
