Yes...I increase my humidity around shed time by misting the plants in the enclosure several times a day (be careful not to mist the substrate and make it damp...it is not healthy for a snake to lie in damp substrate), and I cover 1/2 to 3/4 of the tank lid with a towel to keep moisture in and decrease air circulation like Nate said. Sometimes before a shed, I take my snakes out and let them swim in a bowl of warm water...just be careful the snake doesn't escape! If the snake has trouble with a shed, I make a shed box. I take a washcloth and wet it with warm water and put it and a little bit of warm water...maybe a half an inch in a small plastic storage container...then I put the snake in and put the lid on. I leave the snake in for about 10-20 minutes and then I gently rub what is left of the shed off the snake with my fingers or the washcloth. Then I check the snake...looking over every inch of her/him for any retained shed...I closely check the face, around the eyes, mouth, neck area, and the tail.
