What to do after rampant verticillium contamination?

So I've grown, cultivated and dried 10+ tubs now most of which were contaminated with what I'm pretty sure is verticillium. The question is now what do I do from here? What's the best approach to remedy this? My grow area is behind my couch, behind a curtain in my small studio apartment. My place isn't dirty by any means but I know there's probably verticillium spores everywhere by now after dehydrating ounces of contamed fruits. I don't even know where to begin. I was thinking an air purifier maybe? UVC light?

I would just be extra cautious when handling nee tubs, like make sure you wash your hands/arms/clothes before messing with them. At least for a bit figuring they have a higher presence now but should dissipate in time. But also along with a good cleaning of your space as well as your tubs. I don't think a purifier is necessary or lights esspecially. Just a little elbow grease and caution. And honestly I would probably reccomend that for all contams for the most part. Sometimes I will lysol hard to reach areas.
What makes you say it's vert? Pics?

I haven't had vert issues with mushroom grows, but have had them with growing vegetable seedlings for my garden. Every single time the issue was caused by a combination of one or more of the following: 1. Temps too high 2. Humidity too high (and moisture of the substrate/soil too high) 3. Not enough FAE 4. Not enough air movement
Basically, really wet, hot, humid, nonmoving stale air.
IMHO it isn't about an abundance of vert spores; it's about the conditions that allow it to thrive.

Idk, me personally if I I vert its usually bound for my tubs by the second flush unless I clean everything really good. In my experience even after fruits start developing and fresh air can be increased even more I've still seen it develope. Esspecially if you have a thick canopy it can be really hard to keep the airflow through it all. And if you had some vert nearby, get prepared.
Yes those conditions are where vert thrives, but contact with fruit seems detrimental non the less, I've seen vert spread on very dry tubs also. As well as perfectly good tubs with relatively low fae.
And I think vert. Fungicola is a bit different than the other varieties that re on plants. Idk how much, but I don't think v.fungicola effects planfat.
A big spread for me, I'll harvest tubs and put them on the lids of others, even vet contamed ones, and I've really noticed/suffered suffered concenquences in those cases.
And think about it, vert on plants can grow in well below 90% humidity, I've experienced it on several cannabis plants. Preventing conditions favorable for very is almost like creating conditions favorable for cubensis.
Also I've spread vert from my cubes to my gourmets which was a pain.
Personally ide say it's more spreadable than likely to be a reaction of conditions.

Quote:
The fungus produces a tremendous quantity of microscopic spores, which cannot be seen by the naked eye. It has been estimated that an infected mushroom could conservatively produce 30 million spores within an hour. It has also been reported to take only 4,500 spores per lb. of casing to cause a partial loss and 45 million spores per lb. of casing to get no mushrooms. The spores and mycelium of the fungus may persist in a dry condition for up to six months and can survive the winter months inside a farm or under covered debris around a farm. Controlling the spread of this disease is like fighting an invisible enemy.
It is very bad.
I would personally remove everything, seal the room and use a high-output ozone generator for 24 hours straight.
And throw away any prints that were taken from/during the suspected outbreaks. And cultures that were used if that is the suspected vector.

Yeah sounds like you need to set up a fan or something to keep the air moving back there.

Why bother drying out a bunch of moldy mushrooms? 
Can you paint the place?

Pics of a few tubs that I've harvested.. Seems like vert yeah? I harvested and dried because at the time I thought they were just bacterial.

The upside down pointing caps and striped stem does seem like there could be vert in there. I do see bacterial blotch on a few caps in there too.
I've really only seen stuff like that when my tubs get too wet or have lower FAE. It is usually after the first flush too, after the surface is damaged and exposed to some open air and me in there harvesting...then misting.
I would also wait and harvest that flush if it was mine, it doesn't look too awful (to me anyways). I'll take tubs with small amounts of contam away from my fruiting area to finish a day or two sometimes if there's decent fruits in there that aren't gross.
I would say clean your tubs and area extra well with bleach water or lysol after that tub is tossed. Maybe clean out your misting bottle too, and keep an eye on moisture + fae. If it keeps showing up, start over with fresh prints/cultures.

No ide say it's more psuedomonas bacteria. But maybe some vert setting in. Probably work on your PC approach, as well as clean everything really good and get some more airflow in this guy's.
The last pick shows more psuedo, the black caps around it aborts. Some fruits show signs of psyedo. But idk your tub almost looks like you iverhydrated your coir and you needed to add to much additional fae to compensate, which didn't allow you to keep your humidity up, so your walls dry out and you keep spraying it. How far off is that?

That’s really not too bad. They’ll be fine to eat.
Just get more air moving around the tubs and it should stop.

Looks like rampant pseudomonas bacteria on your stems
