Enjoy these flowers now. It may be the last ones on this orchid for a long time. Of course, you know the flowering cycle drains energy from the plant and roots and leaves grow very slowly if at all while blooming?
Orchid roots must be able to breathe and get fresh air. That is one of the big reason many of us pot with a bark mix that allows air in. Also, phals like to get dry for a day or so. Keeping the roots wet all the time allows rotting and root death to happen.
