How much humidity does common water starwort 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 common water starwort 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 common water starwort at 100% (aquatic), 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 common water starwort is one of them.
Do I need a humidifier for common water starwort?
Yes — raise humidity around the plant deliberately.
