here in Malaysia where it is hot and humid throughout the year, once the plant reaches the dormant phase, i just isolate it a separate growing area out from the reach of the rain. watering is minimal except when the psedobulb shrivels slightly. as for SH, i think should pour all the water out and let the media to be dry.
resume watering and fertilizing once the new growth is about two to three inches in height. (but i do resume earlier than that). congrats on your bloom and hope to see the photos soon
