Question on slow casing

I started my first casing (also my first grow), it colonized to the surface but took about a week and then pinned, since then the pins have been growing very slow, its been 5 days with little growth. I had pin misting and fanning 3 times a day.
I'm pretty sure this is due to a dry casing so what i did was take the casing out, it stayed together well, sorta like a cake, and i placed it directly onto some perlite in a small fc. Im hoping this will allow it to absorb some moisture.
Im wondering if what I did is ok, or if anyone has any other suggestions to up the moisture in my casing.

if it is truly dehydrated, then yes, sticking it on the perlite will help it absorb _some_ moisture. but go take it off the perlite this instant! . . . now that its hopefully off the perlite, and on something suspending it from touching the perlite...like a wire rack, or better yet the original container...lets discuss why not to do that.
fruiting chambers are non-sterile environments...no matter how much peroxide you add to the water, no matter how often you clean it...its non-sterile. just about anything could be sitting in that pool of water getting highly oxygenated. would you drink water that was sitting in a box in a closet for multiple days/weeks? would you eat a mushroom that drank it? ..i sure as hell wouldnt. not only that, but if the substrate suddenly receives water from being directly on the perlite, it can, and probably will slow down even further in its production as the mycelium tries to grow down and grab the perlite. anyone who has sat a cake directly on perlite can testify to this fact.
now that thats discussed, the couple of acceptable ways of rehydrating a casing thats suffering are: injecting _sterile_ water from a syringe, into the middle of the cake, slowly. dunking the casing (preferably after harvest, do not dunk with actively growing mushrooms on it, that are of any considerable size), and one of my favorites, rez-effect

misting is another acceptable way to rehydrate it...though lots have been known to over-do this step. imo, casings should be misted once a day, not three times as in your case, or seems to be your case. and even then, one would usually stop misting once he/she reaches their saturation point of the casing, or...when the first pins appear. fanning 3 times, sure...misting 3 times a day..no. most of the moisture used to produce the fruit bodies lies within the substrate already. while moisture content could possibly be the cause of the slow growth, there are other things you should try altering before assuming its dehydrated. a good sign of dehydration is the casing pulling away from the sides of the container...yet another good reason to leave it in its tub. some other variable factors that more likely attribute to slow growth is temperature, and fresh air exchange.
