I am a newbie, but I can say that I keep my normal humidity on the low side, but I bumped it to 70% or Matilda's shed cycle. She had a gorgeous shed. I mean, I could see where her eyes, upper jaw, and lower jaw were in the shed skin. It was also in a perfect circle that I was able to unroll when I pulled it from her container. I took it to my school (I am a teacher) to show my students. Like I said, perfect shed.
