Basically, I just pour boiling water to hydrate a casing layer, cover and let cool, then hand squeeze right before I apply. No problems, really easy.

If you are not packing in LARGE amounts, tightly in bags. I would think about 1/2 the time you do grain spawn jars.
It's a cooking thing.
It takes far less time. To cook a 3 lb chicken. Than it does. A 30 lb turkey.

I have microwaved my casings for 10 mins on high was getting contams, just on my casing layer
now I PC for 30 mins which has been working pretty good I think I may move it up to 40 mins + if I get any more contams

Good god thats genius!
I'm gonna have to try that a few times. Do ya think a 1:5 ratio would be good? (sub/casing) Thinking that would hold a lot of water.

If you read the chapters in stamets books on casing preparation, whether you look in TMC or GGMM written almost 10 years later, you will find no mention of sterilizing or pasteurizing casing material.
Your are incorrect here RR
pg 130 TMC
Stamets does say to pasteurize
"evenly steamed for 2 hours at 160F"
OR
"bake the moist soil in an oven for two hours at 160F"
He also speaks of hygienic quality of casing soil... but HOW is an average cultivator suppose to know this???
RR your clean procedures must be impeccable
Everybody else, PC your casing!

I've never tried pc'ing or microwaving my casing material. Reason being is; I use far too much of it in order to do it in these manners. But I ALWAYS pasteurize my material for an hour prior to using it. I've seen far too many molds inside of bags of material to try otherwise.

So what exactly are these conditions? I have a pretty good idea but maybe there is something I have missed in my reading.
I would much rather attempt to meet these optimal conditions to save the trouble of a casing layer.
I've heard people say a casing layer will help with flushes after the first, but wouldn't dunking after each flush serve the same purpose?

Correct. You can't have a 'casing' unless you have a casing. What you're fruiting is an uncased bulk substrate. It should do fine, although a properly made and maintained casing layer will increase both pinsets and eventual harvests by transferring moisture from your mister to the mycelium as the fruits draw it out. RR
Although, in another post I read of yours it sounds as if you were advocating a casing layer.

HippieChick employs this method.
Optimal for uncased is 100%RH with good FAE, temp 70-75*F.

That condition would be keeping it near 100% RH. Basically, an uncased bulk substrate has the same requirements as a cake. Fresh air becomes more of an issue though, a large mass of substrate needs more frequent FAE, and frequent FAE makes it difficult to keep RH up. A casing layer is far more forgiving when it comes to the RH - its moist itself, so it holds a pocket of high humidity down at the surface of your substrate, where its needed, to stimulate pin development.
In my personal opinion a casing layer is *always* worth the trouble. Effort spent on prepping it really isn't all that much, and effort saved trying to juggle difficult environmental conditions and having to re-hydrate solely through dunking more than balances out. Again, my opinion (shared by many but not all) so take it for whatever its worth.

You must not prepare your's the way I do . I double sift all the peat . It takes me almost a day to sift all the peat alone . I did do it in big batches though .
Cool mist with an ultrasonic running almost all day makes for excellent FAE , one exchange every 10 minutes , and humidity stays near 97% .

Whatever works for you .

I'm with creamcorn here a casing is worth the effort and remember all situations are not the same. I like the buffering fact that allows for less maintenance in less than perfect conditions.

I have a question for you Hippie Chick,I imagine your ability to fruit uncased substrates so successfully has a bit to do with you running an ultrasonic as well as a cool mist,If I were do buy a ultrasonic I would need to put it on the top shelf wouldn't I ?? And wouldn't it just over saturate the casings beneath it,and if I put it on the bottom next to the cool mist would it even do any good at all or would all the mist just go down and soak my perlite

I put mine in the cool mist . No need for any extra piping
 
and the mist just flows through the whole GH

This may come off as a stupid question BUT...
when you PC/sterilize the casing, do you dump all the casing into the pot or put it in jars or something? How's this work with the water used to PC??

I PC mine in quart jars, a little on the dry side . It spreads easier this way , doesn't clump , and I can spray it to get it to field capacity after it's applied .

A single disk fogger sprays out about 10 ml per hour. An impeller type cool mist, about the same mist amount, or more. Most fogger manufacturers recommend not running a fogger. More that 8 continuous hours. A cool mist, you can run 24/7. I would suggest having the fogger on a timer. So, you don't burn it out. Just my take in the combo.
You can also up-size:
 
 
 
18 gallon plastic drum Fogger, bubble wand, aquarium heater. (all in the drum) Small fan & PVC pipe.
On timers, unit will run a couple weeks. (15 minutes off/on 24/7) At 95/97 Rh output. Without a refill. Plus, easy to refill.
Heater in water barrel, maintains mist output temperature. Simple to build, if you can find/acquire the right drum & fan.
