bulk trays need help with cobweb! pic

A friend has about 15 large trays colonizing and needs some help. He's got some cobweb problems on about every tray. Here's the run down before I ask the questions.
Rye berries colonized via liquid culture, over 20 large spawn bags colonized perfectly.
Poo was pasteurized, spawned with grain in very sterile bust tubs(dish tubs). It was mixed evenly, no layers just straight up mixed. Covered with foil, which is poked about 20+ times with a toothpick. Colonizing on an open shelf at 75degrees.
There are several problems though.
For starters only about 10 of the trays colonized completely. There are several that just stopped. See below for pics.
As the ones that are halted are stopped, mycelium yellowing or "piss" builds up and seems to cause cobweb and or trich.
Next comes the ones that DID colonize and now have a casing layer (50/50+) that was pasteurized as well. All but 2 of the 10 have some SMALL form of cobweb and or some form of the early stages of tric (the white powdery looking mold that almost looks like mycelium).
What should he do? TOSSING THEM IS NOT AN OPTION HERE. The cobweb has been treated with h2o2 twice, and it HAS kept it somewhat at bay, so he wants to make the best corrections possible now to change the tide, so to speak.
The room they are colonizing in HOWEVER, has no air input and has to have a box fan feed it air from the hallway. He has since put a small fan blowing ON the trays, and the larger fan on high to boost air circulation, but he is afraid that this will cause FAE not GE, and therefore screw him anyways by stopping colonization altogether, can this happen?
Can putting these two fans in the room and having them blow air directly on the trays (very stale air room) be the best help here? Or would it advance the tric or cobweb?

Direct air is gonna dry out the sub. Your friend is sure its cobweb and not fuzzy mycelium?
The stalled strays could have bacterial contams. Large amounts of metabs is usually evidence of such. Give em a whiff and see what they smell like. If they smell sour, just toss em.
Cut out any green that appears and treat area around the wound with h202 or salt. Keep green trays away from the good ones.
If worse comes to worse and none of the trays survive, take a culture sample from a clean piece of myc and grow it out, so that you don't have to get more spores.

Doesn't look like cobweb to me. Looks like MYC. The pics suck so it's very hard to make out any detail.
If you see ANY green then you should just toss it. Scraping it out doesn't do the trick in my experience. I've tried using a torch to burn out the contam too. It helped, but couldn't decontaminate the sub. Some people claim that previous contam trays tainted their FCs. Everything they grow in that FC comes up green no matter how well they make their trays. Keeping contam trays is just not worth it. Sure you'll get fruits from trays that have spots of contams, but all your other trays will get contam too. Just not worth it.
There is evidence (from what it sounds like) that these contaminations occured during spawning. It's likely deeply rooted all the way to the core of the tray.

shit.
only 3 or 4 out of the 15 are stalled. why would this be? they smell like a magic marker. if they smell like this and have not colonized by the time 3/4th's of the rest are almost done, are they definitely not going to colonize?
if its deep rooted in the spawning, when he mixes the grain and the poo together, should there be grain spawn on the very top layer? (2nd picture)
or should there be a thin "poo layer" to protect the grain..

Nothing is written in stone here. The stunted trays might colonize. I'm just saying that if you see green then that kills the tray for me. Cobweb is a sign of lack of fresh air and/or proper air circulation. Beef up the fanning/fresh air. I wouldn't use the peroxide water unless you know you have cobweb.
I typically apply a casing layer once my trays are fully colonized.
If you thoroughly mixed your spawn with the bulk sub then you don't need to layer anything. You shouldn't need poo or spawn on top or anything like that. You just want it to become fully colonized then case or not case it.

I don't see any cobweb in those pictures.
I'm not being accusatory here, but it seems as though a huge amount of first timers, (or noobs), are WAY to eager in their grows.
You are supposed to wait, forever I know, for 100% colonization. THEN wait, even longer than forever here, for at least a week for what is termed consolidation.
When your cakes or trays are birthed too early, a WHOLE host of issues plague your grow.
One of them being the so called "stall", which, of course, causes even more grow issues, like drying out of the substrate, mycelium weakness against contaminates, etc.
It's a big kick in the balls, that's fer sure...

Thanks. To prevent drying out the substrate through the holes with all the fans could he apply micropore tape and really beef up the fans?
There's no cobweb pictured, because it had already been treated. The pics are for the trich and stalling.
He's got 5+ years of doing this, always sterilizing with no problems. He simply wanted to try pasteurizing the sub and casing this time and has had these difficulties. He's not being hasty, just quizative.

I'll take a pic of my current trays and let you see what I've got. Be right back...

These trays were spawned on 04 Sept, that's eight days ago. (it's killing me.)
I use a pencil to poke about six holes in my foil cover, which is NOT removed for any reason after spawning to bulk. I cover each hole with Micro-Pore tape. (good stuff)

The heat generated by the running mycelium causes the moisture in the air inside the tub to condense on the walls and drain back into the substrate where it's needed.

It's hard to see through the moisture covered plastic, but I can see the mycelium feasting on my special recipe in there. Yes, it's taking FOREVER. I may be a grandpa before it's said and done... But after all I see is white mycelium, I STILL HAVE TO WAIT ABOUT SEVEN TO TEN DAYS BEFORE THE MYCELIUM IS READY TO WANT FRUITING CONDITIONS! I will keep it covered UNTIL then. IT will NOT fruit in that time ANYWAY! All I'd be doing is drying it out. Might as well keep it where it is, nice and cozy. It would be like inviting an old friend to dinner, and then hurrying him out before he's had a chance to sit a spell. RUDE...
When ever I feel as though I can't stand it I give my trays a peek and a smell though the Micro-Pore tape, and then I put my mind at ease by thinking; No pinky, No stinky!
If your trays are lighter than when you spawned to bulk, they have lost valuable moisture.

You seem obsessed with this idea that pointing fans at the trays are going to cure them. It is not.

The obsession is just because the a/c failed in that room right as the casing layer was being added and most of them had colonized fine. While the a/c ventilation in the room is out, fans seemed the obvious choice to prevent the "stale" air that was definitely causing cobweb. But drying out seemed the issue, and micropore tape seems the remedy.
Thanks for the pictures they are helpful. I will post pics of the flushes.

Micro-pore tape keeps out contamination while allowing for gas exchange. It does not keep the moisture in the trays. Aluminum foil does that.
My primary point is to refrain from introduction to fruiting conditions TOO early.
