Just a question on misting...Do you want to mist your snake directly or is it not a good idea? Someone said it could cause an RI yet others say its ok??

Why I am asking is I am having major problems with humidity :/ I have read I think every thread on the subject and nothing im doing seems to be keeping the humidity at a proper level (water dish on uth, humidity sock, damp towel over screen, ect...) Any other tips? I am going to go get some moss in the morning for a humidity hide but will damp paper towel work until then?

My humidity is a 35...I know, not good!
This is urgent because my snake is going to shed any day now!
