I walked into the room after 8 hours and temp had topped out at 146. I was losing a tremendous amount of heat out the top.
I covered the top of the top with cling wrap and laid beach towels over it to insulate. After a few hours I had temps up to 205-208, which I allowed to run for 6 hours. I’m feeling pretty good that I got a decent kill on pathogens with that temp.
After that I pulled the logs out in the bags to cool to 80 or so, took about 4 hours, added 2 cups of spawn per bag, sealed and shook per the article.
Packed up and ready to go

3-4 weeks now in the garage after which I will bury when fully inoculated. Fingers crossed. Best part is I have some spawn left over so I can go do that dying oak tree in the wooded lot next door 
Totally, and relative to the input cost and potential reward it's a reasonable gamble. Worst case scenario, you stick some logs in the yard and they decompose, nbd, you spent a few hours enjoying a hobby. Best case, mushrooms for years.
