This weekeend is going to be cooler than I expected. How about grafting at 50 degrees? It was probably 55 last time I grafted.
Also what about cold temps during cell building? I was thinking as long as its warm enough to raise brood, the temperature should be OK. I'm not worried about mateing flights and drones as it was warm before and soon will be warm again.
And, would it be a good idea to put like 50 grafts in one cell builder, knowing that they probably all won't take? I'm using a frame with about 25.
