I recently grew a batch of cells for a customer. Planning to deliver them to him on day 14, post graft.
Since late April, almost every day has been 100F or higher, with cooler days still being in the 90'sF.
Anyway, on the morning of day 13, I was working to prepare another cell builder colony, adjacent to the one containing this batch of cells. When, lo and behold, I heard piping coming from the cell builder in question. I suddenly developed "butterflies in my stomach". I quickly prepared some queen cages, then opened the cell builder with the emerging cells. The first bar I removed, had one emerged cell, and two virgin-killed cells. The remaining cells were all emerging, almost simultaneously. I struggled to catch and cage each virgin, all the time thinking of the other two bars, still in the cell builder. Once I dealt with the other two bars, some of those virgins had merged into the mass of nurse bees in the cell builder. I had to repeatedly search through the bees in order to, eventually locate and cage, all the loose virgins. Finally, all were accounted for.
I'm thinking I should put a temperature sensor in with my next batch of cultured cells, to see what temperatures they are growing at.
