I set up a cell building colony today consisting of 18 medium frames full of open nectar, honey, pollen, nurse bees, and sealed brood. My plan is to graft 25-30 larva. The weather turned cooler (upper 50's) for the next 2 days so I wanted to wait until Saturday to do the grafting. Is 3 days too long to wait? The colony has no queen and no provisions to make a queen until I give them the graft.
What's the coolest temperatures anyone has grafted? I do mine indoors. -Thanks
