Death at 106f is bull shit

My fish tank heater shorted out, so I have to use a heat blanket. I put 7 freshly spawned jars in my incubator, and had 14 about 40 percent already in. I set the blanket on high to pre-heat it, and forgot to back it off. The jars were at 120 degrees f for 6 days, and the new ones are growing as normal, and nothing has happend to the ones at 40 percent.
who came up with the 106 thing stamets?

It's 96F and 106F for spores...
And i know that dried out myc. can be put it statis and lost for a long time...Not so sure about heat though, it the metal was Burning ass hot then it really was 120F...if not, then ur themometer was wrong

No man, my thermometer is fine. I could tell just by touching them they was burning up.

so are you going to start incubating them at a 120

No no, I incubate my jars at 83 degrees. 120 is way too hot, and they didnt grow faster at that temp, but they did grow a little.

ya i know i was just fucking with you sounds like luck is on your side i dont know the facts of thermal death just what everyone says but i will tell you this 120 dos not sound comfortable

Good questions. Yeah, Stamets & Chilton say (p. 197 in the Growing Parameters for Various Mushroom Species section): Substrate Temperature:84-86 F. Thermal death limits have been established at 106 F.
Check it out & see if they grow through. I'd like to know. I also wonder (if death below 120 doesn't happen) if those higher ranges might promote contams.

No, your thinking of mycelium. Death for spores happens above 160 degrees. Thermal death limits for myc have been extablished at 106 F. As you said though, doesnt mean always..it seems it held up in this case.

Even if the heat didn't directly kill the myc., I can think of a whole bunch of other high temp problems that might eventually cause death - favoring some contams over the mycellium, high production of CO2, and high production of mycellial piss coming to mind right off. It does make me wonder how that thermal death limit was originally tested, though. Agar plates, maybe?

And what are some factors that would cause it

Once I incubated straw with B+ spawn , temps raised up to 110F. 50% of it died, maybe it didnt get THAT hot everywhere.
Doesnt matter if myc. lives or dies at 110F, one should avoid it anyway.

My incu chamber seems to be fluctuating from low 80's to high 80's--81-88...thought that it was a cause for concern until I saw this post. Not that I wouldn't like it stable but is now less cause for concern.

no concerns just takes a little longer then a steady 86F

Another myth that needs to die is that jars need to be cooled to room temperature after PCing. I inoculated a bunch that were warm to the touch (~110-120 F) with absolutely no problems.

If you're new, and read this, let it cool anyway. You MIGHT get away with it, but I once had reason to dump the substrate out of jars when they were just warm to the touch, and the interior substrate was still hot hot hot.

well, i had just changed my own incubator setup over last month, when i did so my fishtank heater became a lot more efficiant. where i was using something similar to a "heat bomb" (fishtank heater in a sealed container in your incubator), which needed to be maxed out to get the 84-86 F temps, when i switched over to a TiT setup i forgot to lower the temp of the heater, and my thermometer didnt give me very accurate temps because its one of those digital ones with an external probe, the trick is let it touch the bottom so it can sense what your jars are sitting on. The problem was my dangling thermometer just read the air temp in the incubator, but the bottom of my jars were getting cooked and dried. i noticed this in time and some of the deeper mycelium must have servived and sprang back, but some of it was definitly killed off by the heat, and it couldnt have been much over 96, because thats as far as my heater goes to.

Im thinking what mushroom friend said...
Inside of the cakes never reached above 105 or somewhere around there.
120 is to hot for most living organisms, they would die if given enough time or thorough heating.

I can speak for a fact that not letting the jars cool before inoculating will kill spores. Or i had dud spores.
There is still NO reason to tell people that it is "myth". A hot core temperature will kill spores, even if your jars are only warm on the outside.
Its not that it wont work, its just not optimal.
You could incubate jars without lids too! but why increase your risk of contamination?

i call total bull shit on this post , and even if by some miracle and,or it not really being 120 for 6 days , thy would not be growing normal there would be mushroom piss all in that jar any one who has grown grain spawn and let it get too warm like 95 or let it sit in the jar too long has seen the yellow liquid waste build up on side and bottom of the jar

I incubate my jars at 95 and i've never had any problems drying out or colonization.i totally agree with letting the jars cool right the hell down cuz there is no point in wasteing the spores. if you get away with it that's great but my ass it waitin'.
