Whats my humidity?

I have no idea, I have a screen top and I rarely mist so its can't be more than 50%.

CKing, whites treefrogs and many other treefrog run male heavy, so the chances of getting a pair when purchasing two frogs is less than 50%. I am not sure what the number is for whites, but I have five and all five are males...
