Humidity guide
How much humidity does white guinea yam 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 white guinea yam 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 white guinea yam at 70-90%, and wet leaves overnight encourage fungal problems. A humidifier or grouping does what misting only appears to do.
