OK, good.

I have numerous terrariums and keep mine potted, in tall, large terrariums. Have four of these for plants that require higher humidity.

Humidifiers normally do not do a plant much good, since the slightest breeze dissipates the mist from the humidifier.

If you want to try a humidifier, get a mini one like this: https://www.amazon.com/USB-Powered-Humidifiers-Bedroom-Humidifier-moisturizer/dp/B08S16MQNN, that can go directly under the plant and turns off automatically when the water runs out.
