What's the volume of grow space and the volume of air your pushing through???
That's pretty important

Blojo, Cant say the cfm of the fans, not rated, but based on comparable ones on internet, id say between 5-10cfm. 2 per drawer makes lets say 15 cfm. Drawers themselves are 15 cubic feet, and the fans run last 15 min of every hour so... Looking at about 15 air exchanges per hour, or 1 air exchange per minute of fanning. Think this will dry the sub out? *edit* I calculated way off. Drawers are more like 1.15 cubic feet. So its essentially getting over 100 air exchanges those 15 min the fans run. I could run it for less time (if i bought a better timer) or less frequently but then ill run into standing water in the system. 15 min seems to be about the right time it takes to remove all condensation thats built over the half hour of USH misting. Its getting complicated and compromise seems inevitable- but i knew what i was getting into with this beast.

You'd be much better off getting rid of the fan and relying on passive air exchange, i.e. air holes.

There are holes as well. I was looking for a way to keep water from accumulating inside as the humidifer cycles on and off throughout the day. Without any sort of fanning it just gets waterlogged because im not running the ultrasonic through any fogging stages. Im sure they could serve their purpose without too much negative effect on humidity, its just a matter of how long to run how often. I suppose im asking questions which can really only be answered through trial and error. Ill keep at it.

The water won't accumulate if you have enough air holes and aren't running your humidifier any more than necessary. Fans can cause excessive moisture loss in short periods of time although it's not always apparent.
The number of air exchanges per hour means nothing if they're only occurring 25% of the time. The goal is to prevent CO2 buildup in the first place so your mushrooms are getting enough fresh air all the time and not just occasionally when a fan turns on.

Kizzle, Water accumulates, it just does. I dont think im going more than necessary because if i check it frequently, and wait for rH to break the 90s- by that point there are small amounts of standing water and lots of condensation. Air can get in and out all over the place. Through the fan holes. Through holes i drilled. From the small gap that is left at the top of the drawer when it is inserted. Its by no means airtight. Last night i let it run humidifying every 30 min but pushed fans back once every 2 hrs instead of one. Woke up to lots of standing water. Im convinced theyre needed, again, its just how long how often.

Your looking for roughly 3 complete changes an hour... Not sure what happens when you far exceed that mark. I too, have a pump way to large. 1114 gal/hr. 2.48 cfm. Even a 91 qt tub, the big ones, is only 3 cubic feet. I'm almost pushing that through a a minute.
haven't gotten around to slapping it all together yet.,still researching.
Good luck though.

Everyone, i greatly appreciate all the replys and insight ive received, but i think i need to put this thread on a hold for a while. As one user said here im sort of in uncharted territory, and i feel im perhaps overthinking things. Trial and error is whats best for my understanding at this point. My trays are about ready to fruit. Im just going to set it as close to optimal as I can, load it up, and see what happens. Positive or negative results, i will have learned something, and i will share. Cheers. Youll hear back from me when i have something to show (or not). Sincerely mikes cat.

Well i was away from the home for 5 days and let it run loaded with 3 colonized coir trays. Came home to a few babies, and lots of pinning the next day. They grow fast- what was a small white clump in the AM actually had some body to it in the PM. The sides have started to pull away a bit, so i cut back the fanning. Loads of pins coming from the now exposed sides of the sub though. The humifier runs the first 15 mins of every hour plus whenever the fans blow, about every 2 hours. This keeps rH in 90s and prevents any water buildup. Only have to refill humidifier about every 3 days. So this has got me into the pinning stage at least, huzzah! crazy thing works for now.

I am working on an experimental rig which uses a Raspberry Pi microcomputer to control 6 120mm pc fans based on various sensor inputs. Nothing wrong with overthinking as long as you do the requisite research and keep your common sense; UNDER thinking is where you run into real problems.
Invent on, my friend! 
However, I am using the basic SGFC tek until I am absolutely sure this other setup will work as designed. You don't want to be trying to grow in an unproven system... down that road be dragons.

Well condensation shouldn't form near air holes on directly on substrates. So if that's the case it's probably spatter from your humidifier. Make sure you have it on the bottom because water vapor rises but suspended water droplets fall and you don't want water droplets landing on your trays every time the humidifier comes on even if they're not accumulating.

Thanks, ive got it set properly now, it seems to preform differently with the trays added. Whats shown is growing quick so i assume its a happy enough environment for them. I only wonder if the sub pulling away and shrinking is a sign of dryness or just the myc consuming it. I put them in on the early side of colonization, to be honest- about 85-90%. So how could it eat so much before 100% consolidation? First guy out the gate looks ready to pick in 2 days or so, so theres that.

First flush is over and done with, it yielded only around 1.5 oz dried, again from three 12x9 pans, about 1.5" sub. I think I had dried out the subs running fans in such long intervals. They have pulled away from the sides of their pans moreso than I think should occur after one flush. So I found a pretty handy cycle timer on ebay, was only around 30 bucks, and can control to the second. Right now Im trying out 30 seconds on, 9 minutes 30 seconds off. Basically 6 times an hour for 30 seconds. US 15 on/15 off. I hope that this setting will keep both humidity and FAE at its most optimal. Sometimes it will be fanning without mist, providing evaporation, sometimes it will be fanning WITH the mist, keeping the water from condensing on the drawer bottoms. Im happy though that the concept has been relatively successful, I just need to work on other parts of my process, like keeping my coir recipes at the right hydration, and cutting back on the number of contam jars I produce. Here are some shots of how the fans are positioned since I havnt shared any yet.

You most likely would have done way better with a single monotub.

Yeah im not disputing that for a second. Ive got lots of room for improvements my pinsets were very uneven, although let me tell ya they were some dense potent boogers. Intention was never to come up with something "better" than a mono just something unique
