SpaceBaby, I have used Concrobium for non-cult related things and it works very well. Had a water leak in a vehicle that caused the carpet to mold. This treated it well.
My only caution is that in my personal experience, if my tubs get trich, it’s due to spawn, or due to improper substrate prep. I have recently switched to buying a brand new cooking pot to boil water for substrates in, a brand new cooler to hydrate/pasteurize coir in, and a brand new spoon to stir it with. Nothing but water will ever contact these items, in order to prevent any nutrients from absorbing into the substrate that trich can consume.

Hope you are able to get it under control. Fogging isn't a bad idea. I also run a hepa filter 24x7 in my grow area and in my work area too. I don't know that it helps, given my theory on how trich actually gets into a grow, but it definitely can't hurt!

I would take blue and yellow now and wait four or five days to see what happens with green.

Dafuq is the black/greys and is the green verticillium?

I think I have been losing more jars since I tried out the self-stick SFDs on my new LeakProof Lids. Does anyone have similar experiences. I just drilled and RTVd handcut SFDs to a dozen new LeakProofs. Here's hoping that is one of the major issues. 
It doesn't explain the 0% success with bags of oats. After a 5-hour sterilization cycle. 
Look at that stick-on SFD on the left - it’s literally lifting off the lid.
I’ve used those stick ons before and never had the adhesive fail, even after multiple PC cycles but I have a hunch those things don’t filter to their claims. I’ve switched to the thicker style SFDs from myco vendors that I silicone on. Same thing you said you switched to but I bought the kind that come 19mm in diameter so you don’t have to hand cut them. They seem to work way more consistently than the stick on ones.
As for your bags of oats, I don’t run bags but know they are VERY sensitive to grain hydration. Much more than jars. Can’t have them too hydrated nor under hydrated. And you have to be careful knocking them up.

Last plate looks like cobweb mold to me.
RE your first question, sprinkling some table salt directly on the trich will buy you a few days but it’s likely below surface and will pop up around the area a few days later. Sometimes a few days is all you need though.

Nice! Looks like you just need another ~24 hours before harvest so that salt bought you the time you needed.

Kind of hard to tell from those pics. It does look like there might be some sort of mold coming in from around the sides but it could just be the lighting too. But just relax - if it is mokd, then there is nothing you can do about it anyway so just wait it out and see what happens.

Anyone know what's going on here? I've seen it only once before. On the jar that had it before, it didn't recover after a shake. It almost looks like yeast but is the wrong color I believe (yeast is always yellow right)?

That looks like the start of trich to me. How fast did it pop up? Just watch it over the next couple days and if it grows really fast and turns green in spots, that's trich. Look for a different surface texture than the other mycelium - it's not wispy and it has a texture almost like a cauliflower.

I wouldn't blame the casing.... usually not that because most casing (like 50/50) is inert. It's usually contaminated grain. It was there all along growing but just didn't happen to poke through until after casing. That's my experience anyway. I've been getting hit a lot with it lately myself, but mostly due to contamination issues in my room that were getting into my SAB. Scooping it out deeply CAN work if the infected grains are limited to that one spot, but it's a crap shoot and not likely to fix the problem. However, it's free and there's nothing to lose so it makes sense to try.

SpaceBaby, try running a HEPA filter in your grow space 24x7. It solved my issues.

Yeah I have a really nice one too and it was money well spent. The way a SAB works, you'd think dirty room air shouldn't be a factor - things should fall straight down in the SAB. But I found that if your air is REALLY dirty, you bring a lot into the SAB as you move your arms in and out and it can swirl around inside to the point where not having anything directly over open plates or jars simply isn't enough to prevent things from landing in them. Really wild.
My HEPA is currently doing double duty filtering out nasty VOCs from my flow-hood cabinet's drying coats of polyurethane lol.

Ok - anyone know WTF this is? Never seen this before. I shook it at about 85% consolidation (it had the white spots on it then too) and it bounced back quickly just fine and finished consolidating quickly too. I can't tell if this is some sort of response to bacterial contamination or the mycelium just knotting up and wanting to start pinning. The things is, I would think if it were bacterial, I'd have uncolonized grains in there, which I don't. I'm at a bit of a loss. Thinking of sending it to bulk just to see what happens I guess.....

That's a seed germinating. See the cotyledon? Nothing to worry about at all.

We've all been there. The first time you see a seed growing in your tray it's a bit of a surprise - especially wondering how it could have survived pasteurization attempts. Leave it be - it will keep your mycelium company.

That's just bruising. Don't worry about it. Your moisture levels look fantastic and the colonization looks nice too. Just let it do it's thing. Nice work.

Also some other jars that i haven't birthed jet, have some weird shit on them, anybody knows what this is?

First pic is bruising yes. Second pic is a fruit forming…. See the little cap on the top? Needs to be birthed badly.

poornoob said: Hello again lads. A week ago i had some unknown green contam which spreaded slow. Anyway, bleach did its job, for 4 days there was no sign of it. Managed to get my 1st ever flush, 260g wet fm a shoebox. Eating them and listening CCR was amazing, even though its B+ , after some 6-7g of dried for both of us, my hand went gummy, my friend’s also. Anyway, i decided to let the shoebox to give me another flush and possibly for contam to reappear and it did. I ve been growin it for some 3 days since i saw it and it didnt even double in size, id rather say it stays as it is. It appeared few days after my harvest, im gonna post photo so someone might try to identify it.


So that is the fucker i ve been dealing with. Must say that a few drops of dilluted bleach do wonders against it. If i was cutting my mushies with scalper instead of picking them up who know when it would reappear. Even though im noob and this is my 1st grow fm what i learned so far this doesnt look like trich, it simply spreads far too slow. Anyway, hope someone can identify it now with a clear pictures, Brgds, poor noob
There are many types of molds. It can be very difficult to identify exactly what type of mold you have, but more importantly, simply not a worthwhile exercise because whatever type it is, your options are always the same. Toss the box or try to stall the mold long enough to get a harvest. Sprinkling some table salt on it is the most common way of achieving the latter. I wouldn’t use bleach. You don’t want any of that getting on things you ingest.

5/8 have no visible signs of contam.
Going to toss these and try again.
Thicker verm layer and up the time in PC by 30mins.
Since you have a pressure cooker - why don't you just use a filter on the lid instead of going with the dry verm layer? If you use a synthetic filter disk or polyfill stuffing on the lid, you don't need that dry verm layer and the filter approach is much more reliable. LMK if you need links to teks on it.

LMK = Let Me Know.
If your one piece lids are air tight, then the polyfill/SFD filter setup will work just as well with them as it does with bands/lids. Fill a jar with water, put the lid on tight, hold upside down and shake. If no water leaks out, you are good to use polyfill filters or SFDs on those jars/lids.
