Mister, fogger, or other solution to raise humidity in 18 x 18 x 24" Terrarium?

This is the "fog box" concept, using an ultrasonic transducer.

It will not "push" the fog well to the tank through a hose, so will need an exhaust fan on the tank to pull it up, but that accomplishes air movement and humidification at once.

Sure, as humidifier would push the air into the tank using it's own fan, but I'd expect less ability to control the flow.
