Grif...thank you for replying! I understand that the substrate will dry out on top no matter what, but with the light petsmart pushed on me it dries it out bad. I've stopped using any light except for the infared heat light. I hope this is ok...? There is a lot of ambient light from windows and other lights I have on. I'm gonna get the reptifogger today and a CHE/fixture. I will the. Order the hygrotherm regulator from amazon. I just feel like I'm doing my little guy wrong by using lights, by not using lights. Do pacman frogs need additional light or can I just put it aside and let the natural light work. Please help lol...
