Where Should You Put a Humidifier for Houseplants?
Quick answer: Place the humidifier where mist can disperse into open room air, not directly against leaves or beside the humidity sensor. The goal is to humidify the room—not one wet corner.

Bad placement
- Directly under leaves
- Next to the hygrometer
- Inside a closed cabinet unless the setup is designed for it
- Against a wall where condensation can build
Where should the hygrometer go?
Near canopy height in the area the plants occupy, but outside the direct mist stream.
FAQ
Should a humidifier run all day?
Not automatically. Use actual humidity readings and automatic control when available.
