Hey guys noticed today that my female ball (petra) her eyes were a cloudy blue and she has been inactive around her vivarium, guess its time for her shedding phase. I have increased the humidity in her viv to 60-70 and added some moss to her hide and have changed her water (which gets done every couple of days anyway) my questions are:

How will i know when the process is complete?
What do i do if she has a bad shed?
If i cant see any skin in or around the tank can i look in her hide?

Thanks guys
