You can mist the enclosure to help maintain 70-80% humidity with either dechlorinated tap or distilled water (prevents water spots); but avoid spraying frog directly. Ceramic Heat Emitters (CHE) are very good as heat sources and outlast many bulbs saving money in the long run. Just don't go over 60 watts and control them either with a dimmer or a thermostat.

Pacmans can be very destructive to plants. You can try a Pothos plant, they are very hardy. However if your Pacman is an albino, recommend use silk plants because you can't use daylight with them. Shredded coco is a poor plant substrate. When growing plants, ABG type soil is recommended. Good luck !
