I have two baby reds coming in and i need help. I read up on these creatures and i got a better understanding but i need help on the humidity in the enclosure. I was planning on constructing my own pen. I dont know how to keep it humid. I am afraid of getting them sick by overdosing the enclosure with moist and dampness. I planned on having one humid side with a hide and temperature area of 90 degrees. But i dont know how to keep humid. Do i spray the substrate itself or just the toetoises? On the other side its cooler, and it also includes a hide with a temperature area of 75-81. This side shouldnt be moist, and it should be dry, corrsct? Which aide should the food and water bowl/tub be at? Also how do i keep track of the humidity ranges? Thanks guys!
