fuck the mushroom god

I don't know what's going on, but something is terribly wrong. A couple of days ago I posted that my shiitake yield was at 24 %! Shouldn't have done that, guess it provoked the anger of the mushgods. I tore up the next 40 bags to put them into fruiting. And in a large amount of them I found this:

Green spots near the filter patches. I presume it is trich spitting spores om my precious blocks. They've been fruiting for about 4 days now and I can already see that pinset is not as massive as in previous batch. The blocks looked alright though when I got them out of the bags. No signs of contams, nicely popcorning and beginning to brown. Just like you want them to be.
I've been thinking of several possible causes. 1. I used ash woodchips that I made this winter with a shredder with our own wood. May be that's too funky to use in shiitake bags.
2. The air circulation in the incubation room is not good. I've got about 500 to 600 bags sitting in there. I'm going in and out all the time, thought that would bring in enough oxygen to allow them to breathe. However, I've been turning the bags lately because I saw that the sides of the bags that are turned towards the wall and thus less exposed to the incomming air, were not evenly colonised. here's a pic of one of them:


I've put a fan in there to mix the air a bit and I can see the patches that were not properly colonised recovering. I'm not sure though if this will eventually affect yield.
3 Third possible cause is that the incubation room is too dirty, sporeload of the incomming air is too high and eventually the bags become contaminated after two moths of incubation. Solution would be putting in a door and a ventilation system with hepafilters.
Anyway, for those who are thinking about launching a commercial set up, this post shows clearly that it aint easy!!! Thanks for all input!

I've been told by the Fieldforest.net folks that Shiitake don't grow well on Ash logs....so I would assume that would be the same case for Ash chips. They recommended I try the Golden Oyster on the Ash if I had to use Ash. I would assume some type of pleurotus ostreatus would spread faster through ash chips than shiitake.

I want to ask something. When you put substrate in bags, were the wall of the bags dirty from substrate? Maybe the main substrate colonized but that substrate on the inner wall of the bags didn't and than got molded? Because healthy mushroom substrate don't get moldy, and mold doesn't grow on plastic bag either.
This shouldn't affect healthy blocks, but you could always rinse them with water if you are worried.

Yes Chief, it sucks. Now I'm starting to pose questions about the woodfired boiler set up, after your remarks about contams during transport to the lab. But I (hope)don't think it's that though. May be you should wait a bit with your outside set up. Magos, thanks for info. I knew that shiitake doesn't like ash logs, but I was hoping we could get away with it using chips. Shouldn't have been experimenting though, too dangerous. I didn't do all 600 bags with ash, after 80 bags I switched to nice clean woodcurls again. pfff Strange thing is that a part of the ashchips bags produced fine with high yields. So I tend to think the problem is aircirculation in combination with a high sporeload in incubation room. Sure thing is that the mushroomgod is having his/her laughs.

Yes Roger I rinsed them all after getting them out of the bags. They all got excessive mycelium growth in inner walls of the bags, lots of myc piss as well. Bad sign I guess. Here another pic of an unopenend bag


This is what it looks like when it comes out of the bag

Well if the blocks are not contaminated now then they should be just fine. About 100 other things can affect your yield and timing of your yield.
I am with Roger on this one, substrate dust on the bags surface eventually moulding. Don't think anything is getting through your filters. I thing the Mushroom God in this case is just trying to wind you up a bit!
Nice shiitake you posted in the REG thread, you might find you get thicker, larger mushrooms on the second flush.

Well your Mushroom God sure wound me up! And not a bit, a lot! Any ideas about the bags that colonize irregular. Are these uncolonized patches the result of lack of O2?

Dry substrate, un-mixed substrate, denser substrate. Any or all would be my guess.

Bacteria too. My shiitakes will eat trich in the time it takes to brown as well as this yellow mold that shows up when they suck in ambient air on cool down.

So O2 couldn't be the cause, or is it just one of the 100 possible causes? Arghhhhhhh!

Seen lots of colours, but didn't see yellow yet Drake! Guess I've been lucky so far. Thanks for warning!

Frogs can carry salmonella, I wouldn't want them in my fruiting room.
Spiders on the other hand, the more the merrier!

Surely that's only if you under-cook them?

That looks more like a toad. Toads are only problematic when they burrow holes. They could dig out buried substrates. But that's not the case here. Otherwise they're great especially for slugs.
