How much humidity does cuthbertson's dendrobium need?
What actually works
What works, in order: a small humidifier nearby (by far the most effective), grouping plants together so they share transpired moisture, or standing the pot on a tray of damp pebbles (the pot base must sit above the water, not in it). A bathroom or kitchen with a window often suits cuthbertson's dendrobium better than a living room.
Why misting is not the answer
Relying on misting. It lifts humidity for a few minutes at most, then it is gone — it cannot hold cuthbertson's dendrobium at 75-90%, and wet leaves overnight encourage fungal problems. A humidifier or grouping does what misting only appears to do.

Only around one plant in six actually needs this, and cuthbertson's dendrobium is one of them.

What are the signs cuthbertson's dendrobium needs more humidity?
Crisp brown leaf edges and browning tips are the reliable tell. Yellowing whole leaves is usually a watering issue rather than dry air, and slow growth in winter is normally low light — humidity gets blamed for a lot it does not cause.
