does anybody know what is the lowest temp that you can have your jars colonizing in before it breaches that line between stalling the jars growth, and myc death. the breaking point temp that myc can no longer withstand.

i know ideal temp is 80ish, and in the high 60s or low 70s will just make the jars take longer to finish. but im looking more-so for the temp that is just too low for myc survival.

I was wondering something similar, Does freezing in the winter kill mycelium? Are all the shrooms come spring the result of spores, or does the network go to sleep and survive the winter?

Just my curiosity, but how well do spores handle freezing? =]

I've seen clumps of myc that have been frozen for a month recover and fruit (poorly)

so do you think that freezing is the breaking point? but it takes a while for it to totally be killed off? if so then we have to figure out how long the timespan is from freezing to actual myc death. if this is correct than one month is enough to damage it, but not kill it off.

I have had a corn casing pin and actually form a good-sized abort in the fridge. Granted it took weeks. I'd guess the stall-out is between 30-35 degrees (but then it's just suspended - I've had frozen cakes come back and fruit fine); death is at 105-106. I don't know if there's a point where you kill fungus by it being too cold, though I'm sure there is, I just don't know what it is because it's probably really cold.

brief exposure to freezing temps won't kill everything
but prolonged freezing will.
