My Ultrasonic Humidifier Setup-Please Critique!!!

Hello out there. I am new to mushroom cultivation and I want you guys to check my terrarium setup before I put my cakes in(which are consolidating right now).
I know that pearlite is the easiest method for maintaining humidity and that I could just follow RR's videos, but I had an ultrasonic anyway I just kind of want to do something different. So here it is:

I have one 13w, 6500K bulb for lighting. The bin has four total 1/4'' holes drilled on the sides and 6 holes into the bottom. I hot glued this clear plastic material on top. Yes, I know its pretty jank, but its what I had to work with.

As far as the ultrasonic goes, I did a little modifying. I see some people, if they even use ultrasonics, have them set on timers that run them 15min. on the hour or what ever because they simply provide too much moisture. Even if you get an adjustable one, the lowest setting still makes a terrarium fog up alot. Since it runs on a timer, they often need to have some other method for FAE, like running a cool mist. At least thats what I have picked up during my research.
What I have done here is modify the circuitry so that I have absolute control over the added humidity it produces. The amount of moisture an ultrasonic puts out is proportional to the vibrating frequency of the diaphragm, which is proportional to the resistance between two points on the control circuit. I rewired the potentiometer(adjusting knob) so that it is solely responsible for providing said resistance.
The end result is an ultrasonic that produces a constant airflow into the terrarium that can be adjusted from room humidity, to full on fog, and everything inbetween.

Im trying to calibrate at what level will be ideal for BRF cakes. The above pic is what the inside looks like on a medium low setting after about 30 min of going. There is a small amount of fog and the sides collect a layer of condensation. Im worried about over saturating the cakes. Is it acceptable for there to be fog? I guess Im just looking for way to tell if the humidity is the right level without spending money on a precision hygrometer.
Any advice, critique, words of wisdom would be appreciated.

No words of advice from me.
Just waiting on it to be full of cakes.

Looks like your tub could use a few more holes.

He's able to pump air into the tub it's hard to say right now if he's going to need more holes or not.

I run an ultrasonic on a humidity switch. This works pretty damn well, but almost everyone runs on a hard time cycle so seeing this alternative method is pretty neat.
Nice move with the pot! 
Watch your water consumption, make sure it's going to be reasonable with that running 24/7. I know I can go through some water rather quickly if it gets dry out.
LegalLife, Why would he need more holes? He's pumping in fresh, humid air. You don't want so many holes that there's too much fresh air. That'll just dry everything out.

#1 Because there is such a thing as too much humidity for many species. With that high of a humidity you are gonna trigger great primordia formation, but cropping will be iffy from there if the humidity is kept that high. you want 95-100 for primodia formation and 85-92 for cropping.
#2 If he tries to compensate for this by throwing the humidifier on a timer, he will be lacking the FAE it was providing.
#3 If your humidifier is blasting out so many CFMs but the resistance in your tub is too great, its gonna create a backpressure on your humidifier. (Burn it out quicker)
Sorry guys seemed logical to me.

If you can keep FAE flowing like crazy but can maintain your humidity, you will get monsters. Ever wonder why nature does better at growing mushrooms than you? Or why in Cali you can get 12 lbs a plant from weed? Because we are trying to mimic the outdoors. Its NOTHING BUT FRESH AIR. Huge shrooms that go on for fields, weed plants 20 feet tall harvesting 25 grand from a single plant...
Youll have to pitch that hole too much FAE thing by me again.

He'll be using timers and spending time messing with it trying to get his settings right. My question was why go and drill more holes in your tub if you don't know if you need them yet? I understand you can tape them up if there is too many but there's no reason to do additional work that isn't needed until you know that you'll need more holes.

I actually plan on not using a timer, running the thing full time, and just adjusting the amount of added humidity that the humidifier supplies(made possible by my mod.).

Wowzers...
Well 1 and 2 are moot points since he's using the pot to adjust the humidity of the air developed by the ultrasonic. He's not running saturated air into the tub. He's running in that 85-100% RH air right into the tub from the get go.
Nature don't grow shrooms better then me, or you.
This isn't weed, which nature alone won't produce 12lb plants.
I should clarify my post, as I made a mistake. I said "too much FAE". I meant "too much dry outside air". Which will come rolling into the tub if there isn't enough back pressure created by the ultrasonic.
Either way I'm starting to piss up a rope here. Only OP will know how many holes he'll need in there. He'll have to dial it in and adjust it if needed.

I curious of how well the cakes will pin with a high humidity. This should be interesting.

By doing the dunk and roll technique you provide a micro climate on the surface of your substrate that already gives you great humidity.
A big part of pin set formation has to do with FAE, lighting and evaporation of moisture on the surface of your sub. Not necessarily in that order.

I was thinking about skipping the dunk and roll tek because I will be able to adjust the humidity as high as I would ever need anyway.

Not sure why you'd skip the dunk and roll, even if you're using your set up it will still be beneficial to your cakes...

Ultrasonic isn't going to provide FAE.

Im running the ultrasonic full time and there is a decent amount of airflow from it. The thing runs off a small computer fan basically.

he'll get fruits though if he doesnt soak the hell out of them with it.
he's got a few holes in there.
its like a PMP except instead of fishtank bubblers through water, its a US

Ran a ultrasonic 24/7 on low into tub with 20 cakes and no pearl. The fog was thick and could not see the cakes through the fog. Great pins and large fruits.

Thanks MushR, Your humidifier contribution is extremely interesting, this should be of particular interest to medicinal mushroom researchers. In order to alter the frequency of mist particle generation, could one modify the inner functioning of a similar model of ultrasonic humidifier to obtain the same results ? It appears to be a connection swap out with a potentiometer of greater resistance.. Does this describe exactly how you have modified it? Nice work.
