" To date, I have seen zero evidence in
support of the hypothesis that photoperiod is a determining factor in colony buildup.  On the other hand, I have seen considerable evidence to the contrary.

  I am a bit confused here. Reading your pollen sub trial brought me to the conclusion that stimulative feeding in fall was a dead end,  all hives pretty well dropped to the same levels,  then resumed in the spring. Based on stores could do 2 rounds of brood on body mass.  How does that square with the suggestion that buildup can be done on artificial stimulant? My takeaway from that was come Jan they started on their own,  I assumed that photoperiod was a major player in that?
