I have a 5 month old ball python, he shed a few weeks ago and we had to peel most of it off as it came off in bits, he is ready to shed again, his eyes have been blue for the past 4 days but i cant seem to get the humidity up in his viv. the temp is fine and i am using bark as a substrate. put a handful of fresh, damp bark in the other day and it went up to 77 but now its back to what it was 50. any suggestions please. was told you should never mist a balls viv a the snake doesnt like it. this is my first ball/ thanks
