humidity?.....should i keep an eye out on it? is so...what a good temp for it?

For Cornsnakes I believe the Humidity should be at about 50% Just gently spray the cage once or twice a day. That's what I do anyways...

you really don't need to worry about humidity unless they are having shedding problems then you can mist them. but like i said it's not a big deal, just make sure they always have a fresh bowl of water

as for temps, around 80 on the hot side and 70 on the cold

Oh ok so mostly just when they're shedding? Thanks. I thought it was all of the time.
