I put 5 frames each of Pf foundation in three hives on Sunday. I gave each hive a gallon of 1:2 syrup, because I mixed it wrong. It was suppose to be 1:1, but I forgot half of the sugar. Then I realized that I forgot to put wax on the foundation, So Monday night I wax some to swap them out with. I went into the hives today to swap the frames out, it was sunny and 62 degrees. Each hive had started drawing out on the surface of at least 70 percent of all 5 frames.
