From Team Plant Protector: Brian Cottrell, Christine Cottrell, Joe Gonzalez, Ruby Hsu, Chih-Wei Hsu on Hackster.io:
In order to efficiently distribute water and nutrients to our plants regardless of the shape or size of the planter, we place a small inexpensive ultrasonic humidifier into a 3D-printed enclosure so that it would fit in the base of the planter and allow air to flow inside so that it could be pushed through the vaporized fluid and into the interior of the planter.
