The down side of being gone so long is that I have no idea when (if) my bioreactor hit higher temps. I'm assuming the best and am going to find and add worms.

Mine just dropped to 84 today after 1 month. I noticed about 2 weeks in, it started dropping a bit, but when I watered, it raised back up a bit and maintained (mine is indoors and I don't think it needs water every day...and its in a IBC tote as well).
