I kept mine at a high humidity, between 70 and 100 percent (to the best of my ability). In mimicking nature, the humidity levels rise overnight and lower during the day. In the case of this species, upper 90s percentages in the evening, 70% during the day. Of course, controlling humidity isn't always easy depending upon the setup. Temps are ranging from 50F at night to 70F during the day in their native land right now.
