I've read somewhere when I first found my snake to keep it around 40-60% humidity in the terrarium("moderate" humidity). I've been noticing in this bigger terrarium I've got him in now the humidity is staying at 40%, so I've been misting the cage once or twice a day. It'll go up to 50-60% for a little bit, but not for very long. Is 40% ok? Or is the misting a little every day good? OOOR should I be misting more?
