Hercules and Hazels tortoise table doesn't have much if any humidity. They have a hide and I try to keep it damp in there but it doesn't seem to help..it dries up too fast. The table doesn't have a top and that's probably why there's no humidity. How can I get it humid in there fairly easy? I mist them every time I check on them which is at least 4 times a day. I soak them about every other day. The substrate that's in there is cypress mulch. How do you keep your table humid? Thanks!
