I only have to spray the inside of the enclosure twice a day to get the himidity up to 70%... thats the only time really, or if it drops below 45-40 I spray to get it back up to 50 when she is not in shed...
I dont ever spray the snake...cause she is usually hiding I guess, but if there was a stuck shed on or something like that I still wouldnt spray her but I would give her a warm bath to help get if off...
