Sterilized coco/verm went green?

sterilized for 1 hour inside oven bags. i do this all the time. this one sat out longer than normal. usually it turns to dust.
1. i thought spores cant germinate on coco... 2. maybe my bag had a hole in it..? but that brings me to #1 3. how does sterilized, uncontaminated cvg go green without adding/opening anything?? EDIT: 4. i have 5 other bags, all green inside. wowzah?
derp?

no. ecoearth.
the only thing i did differently was how many bags i PCed at once. i crammed 2 bricks worth into 6bags and jammed them into my aa915. maybe i didnt PC long enough since i had so much mass but that brings up..

Hmmm. Yeah you're right tho. This is interesting for sure. Cuz technically you don't even need to sterilize cvg. Buckets work for most everyone.
Now I'm curious. I also use Eco.

Mold grows on coir fine. If there's already germinated mold somewhere it only takes a micro fragment to skip germination. When it cools down it could suck something in. Then being in a bag with little air exchange encouraged growth.
Beats me but I would stick with the bucket lol

i do bucket. then i pc. the pc is really so i can store it longer but thats kinda retarded considering how easy mr bucket makes things.

im thinking something feel into the post bucket tekked coco and i didnt pc it long enough? or my shitty filters failed and something sucked in the bags during cooling?
either way. the problems are created by me, the cultivator.

Very weird that that would happen without even opening the bags. Surely something must have gotten in there. I'm not sure how they source or quality control coir, but I've been finding a lot of seed husks and shells in my bricks recently which worries me. Maybe in your case a longer pc time would help, just in case there is something resilient in there. Idk if you saw my comments in that thread a while back, but I tried sterilizing cv a while ago and had total failure pretty soon after spawning. ):
Edit: for the record though, I usually don't use ecoearth. The pet store closest to me has a brand called "exo terra"

It went green, that's mold. Molds are killed well before sterilization. The problem isn't from sterilization it's something else

:this: 
I had a massive problem with mold before, I think it started from some bad spawn but then just kept continuing onto clean tubs from fragments of mold mycelium, the green molds. I did not understand this at the time, and just kept focusing on tightening up my culture and spawn work. But it would completely boggle me, instead of seeing the typical crystalline white patch of Trich coming up thru and spreading, sporulating at the edges, the mold would start as tiny dark forest green specks, smaller than a dime, that would spread from there. I would also get what looked like tiny green pin pricks of mold dusted randomly on my casing layers.
At the time I had thought , and most others would tell me, that clean spawn and a properly pasteurized substrate/casing (or bucket coir) *would not* get mold from the environment. But then I had a tub with green mold and a crack in the bottom leak water down into the tubs below it in the stack and the mold would grow from where the water poured in. In the end what stopped it,aside from tightening my shit up, was cleaning my grow room out very well, fruiting my tubs to another part of the house for many months and keeping my spawn in clear totes with loose lids. And so far I have not lost a tub on the first flush to mold yet, a couple on late flushes though.
I digress :
All sorts of shit gets swept into coir, I usually use Eco Earth too because its so easy to get but I have found things like straw, bits of metal and plastic, etc stuff like that I've also heard of people finding the odd seed or various grain when mixing up their coir. So its very possible you sterilized something like wheat straw or grain and that's why it contaminated. It would have happened regardless of how you prepped the coir most likely
I love coir though , its all I work with for cubes, though I usually add a couple quarts of verm and handful of gypsum.

If some Trich spores survived the heat treatment because the duration of the PC cycle was too short and the bags were crammed, then it would be very easy for the Trich to germinate in the coir that was sterilized.
Trich grows best on sterilized substrates. I was also reading that bacteria like Pseudomonas (spelling?) and others inhibit the growth of Trich in subs..

when i did the bucketting for that batch i even made a shoebox right out of the bucket. worked fine.
as i retrace and read the posts id say my issue was filter/bag failure. solution is to stop pcing my coco. and bucket as i go.

Thats not nec true Bod...
If you bucket something and don't break up the brick I'm not sure there's a guarantee that all of the coir will reach high enough temps to kill all the Trich..
Convince me...Seems like there could be variables...

As for coir...Anything that sits in a fresh water lagoon in the tropics for months at a time is going to be loaded with Trich in many cases I would think. Some more than others..
