looking for critique on this shiitake
    #23852518 - 11/20/16 07:26 PM (7 years, 2 months ago)

how does this mushroom look? its one of my first harvest. i plan on selling to the restaurant market to begin so i would like some opinions on how this looks quality wise, what could be improved upon.





I figured this is the appropriate size for the restaurant market. i should note that this was taken fresh out of the chamber.

:like: I'm not a shiitake person (yet) , but looks good to me. I think I've read they need extremely high humidity for the stems to be tender.:goodluck:

i think they look pretty good. have alot of mutant shiitake so im going to have to adjust my substrate recipe. i didnt expect so much feathering, must be a strain genetic quality. these were grown in 95-100% humidity.

There's something wrong with that shiitake too. Gills are irregular wich indicates nine out of ten cases that you got a problem somewhere. Either substrate or sterilization related.

He means you may have caught bacteria from unclean handling or tools, or the substrate was not sterilized enough.

I'm not 100 % sure either, the only thing I can tell you that every time I saw that, there was some kind of problem. In my case it was most of the time a sterilization problem. My blocks were not sterilized long enough and the mushrooms that came out looked a bit like yours. I saw your picture of the two blocks. One of them seemed to have a sterilization problem. But it's hard to judge from here. May be you can explain your sterilization procedure a bit?

Step 1, blame the spawn. Step 2, blame the substrate or cooking. Step 3, blame yourself or tools. Step 4, blame the grow area.

sure. the blocks and spawn were made and sterilized in a 23q presto pressure canner for 1.5 hrs and left to cool overnight on the stove top. from there the pc was moved to the laminar flow hood and opened, bags removed and placed in front of the hood. the bags and spawn jars/bag was wiped down with 70% iso, and the transfer was made. Unicorn 14a bags were used.

after 8 weeks, some bags were shocked 24 hrs in the fridge, some were left in the fridge for longer, 2 days to a week. some bags were put in a chest freezer set at 10 degrees Celsius for 5 days. the reason for the different techniques is because i am testing out different methods to find what works the best.

after shocking the blocks were placed in the chamber with the bags on some had pins showing some didnt. after a few days in the bags they were ripped off and some fruited others didnt.

still far from dialing in this process.

That sounds good, can't be a sterilization problem. I'd put the grain in for two hours, but may be you can get away with one and a half hour as well. Then it must be like feather said a spawn problem, probably bacteria or rich in your grain master. Don't think it's a supplementation problem. You can supplement with bran up to 20%.
