Hi, I am currently using a 40GAL exo-terra tank with a mix reptibark/sphagnum moss as substrate. I want my humidity to stay at 55-60 when my ball python is not in shes but it keeps dropping… I have done everything I can but nothing is working? It will start out at 60 then gradually drop to the 30’s overnight… I now have to mist it every 2 hours to maintain it, but I cannot do so when I’m sleeping or at school. I’m worried that my excessive misting will cause problems for my snake. The temperature is 95 at highest and 78 at lowest. Someone help
