Augie, I don't know where you are in boone county, but picking Columbia as the middle of that county, your sunrise is 6:24am and sunset 6:13am so you are just under 12 hours photo period. It seemed to me that at least for us northern folk that we needed about 12 hours and 15 min or so to get egg strands. Someone with spare time could look at the 2020 thread and see what dates each person had and look up sunrise and sunset for that locale to double check if daylight hours is the real trigger.
