Horrendous Con tams - Trich Infestation? - Where to now?

Hi there - I have dumped 10 boxes in the last couple of days. Weirdly the only one that is going string at the moment was made from a multi spore syringe and just coir out the bucket.
Others that have gone have been from agar, with PC'd coir etc. Would be brilliant if I could get some advice on what the contams are and what to do now?
Bleach everything in the house? Move my flow hood? Is there anything that can get rid of spores from inside? I figure I must have something really wrong somewhere.
Jars PC'd for 90 minutes Bags for 120 minutes
Most boxes on a 1:1 ratio
Hope someone can help because this is getting really heavy!
Here are some pics of the horror...

Dude, I think the problem might be that you PC'd the coir and thus sterilized instead of pasturized, making it more susceptible to contam.
I feel for you bro, that really does look horrific.

Thanks man.
I actually think it might be because I am doing bad casings. Going to stop doing them and see what happens!
Fingers crossed.

 Coir ain't poop/compost you can pc that stuff all day. Howd you prep the casing/what's in it?
Post pics of your jars/agar work. Moldy tubs dont help us.

Hey buddy.
That looks like it's gonna come down to bad spawn but I gotta ask. How are you achieving FAE with these units? A loose fitting lid on a shoebox can provide FAE but those look very, very wet.
You can PC coir but there's no reason to.

mushboy said you can PC it all day because it's not poop/compost because what he meant is that there's no microbial colony fending off contamination with coir. Coirs anti-fungal properties come from it's relatively hard-to-access nutritional content, and itss oils and its acids that are naturally found in pith. It's contamination RESISTANT not contamination PROOF. It does not matter how resistant coir is when you introduce bad spawn with living mold mycelium it's fucked. It's done. Mold spore germination is the resistance.
Poop and compost rely on microbes and will contaminate easier if you kill those off.

ime coir has never contaminated even when leaving it out for months as a test. look up its purpose...

Coir is contamination resistant, not contamination proof. Coir can sit out in the air fine as you please and be fine, especially if the top layer goes dry.
It's contamination resistant because it's not an ideal germination surface for mold spores. They can germinate on it but it's difficult, even more so difficult if there is just a pile of it sitting out and the air is not humid nor stagnant.
However grains and the things we use to inoculate grains are highly susceptible to contamination, especially by molds that intertwine and feed on cubensis mycelium. Once you introduce grains to the equation you change things considerably. If you're experiencing contamination before the first flush then you've done one of two things.
1) Provided an ideal germination environment for mold spore. Mold spores are all around us in our homes and it only takes one or two out of the abundance that land on your coir to germinate and contaminate it. If you have high humidity but no FAE then you're begging for mold.
2) Bad spawn is most likely the culprit, nearly always if you experience mold before the first flush. Mold SPORE have a hard time on coir but mold MYCELIUM does not. Cubensis sucks rusted reindeer nuts at fighting trichoderma and other molds so if you have 99% cubensis mycelium and 1% mold mycelium hiding in the spawn then that 1% mold will grow until it dominates the tub.
Judging by those pictures the problem is far worse than 99/1% as the mold has far, far outcompeted any mushroom myc.

Thanks for the advice.
Casing wise, I have been making a 1:1 mix in the tub and then adding a bit of extra mix on top to cover all the grains.
I have now switched to just coir, no mix of gypsum or verm too to just go slow and work up
