Bad shed, ive tried everything

[Pythonian]

OK here is the situation. he tried to shed, unaware of the situation i fed him. now it seems he is either too damn lazy to shed or forgot to do it. I saoked him for about 45 minutes the other day, most of the shed came off, leaving the area about 4 inches from his head to mid "neck" area. he is soaking now been almost an hour and only a little bit came off so i put him back to soak for a while longer.

its not the bad shed that worries me, its his apparent lack of interest in completing the process. he spends almost 90% of his time on the cool side of the enclosure. the warm temps are 83-85 even with the AC on and the cool side sits about 77-81 not a huge difference i know but still the best i can do until i get all the duct tape on the lid set up right.

its ok to feed during a shed if he isnt trying to get it off he probably doesnt care but im sure hell let you know if he does

Get the temps higher. What is the humidity?

[Pythonian]

humidity is around 50% i added a bunch of moss today to help with that. like i said im working on the duct tape cover. I finally did get the last bit off a few minutes ago, hes fine now. Im wondering since, before i had him the previous owner barely fed him, is he just inexpirenced? or is humidity to blame?
