Extremely Slow Colonizing...

I started several jars two sundays ago (so it's been ~11 days) and they are just barely starting to grow mycelium now. They have been incubated between 75 and 85 for the whole time, at some point the temperature rose a little too high to 100+ for a little while. Could it be that these jar's spores got killed by the high temperature and are colonizing slowly because most of the spores died?

well thermal death for a mushroom is 104 farenheit idk aboput spores though i guess it would be the same .. maybey most of yor spores dided when your jars got too hot. did the temp rise over 104 u think???

its actually 106 that myc is commonly believed to die, but that's not a hard and fast rule, people have cooked it by accident at even higher temps for short periods and it recovers... i remember somebody who posted a goof on here where they were exposed to 120 for a while and after a day or two started growing again... spores are even sturdier and won't die until exposed to higher temps for prolonged periods of time (think about what we go through to sterilize to kill mold spores!)
that being said... its probably alright. if you've got white spots now and didn't before its safe to say the spores lived right? :-)
ive seen jars where one or two of the innoc points took off in 3 days time while the other two or three in the same jar took several days longer before anything happened... people have also reported jars that did nothing for weeks then all of a sudden took off after they were believed to be a lost cause... don't worry yet unless those little spots of myc stay little, its a slow start for sure at 11 days but not necessarily destined for failure.

this is why i say people should just leave jars at room temp. you can't eff that up. unless you going to spend the time and money to make a reliable safe incubator still to free heat and room temp. whats an extra week combined with complete failure.
