First off, I understand your question a bit better, Danno. I am not qualified to answer. I thought you were asking about the addition of the deep. I see now that the question was more about timing of treatment.
Secondly, I was kidding about being black-balled. I was attempting to lighten up a bit.
I definitely see your point about the posts, though. I don't see why some posts, not mine neccessarily, get few responses. They are legitimate questions about bees, yet others about off topic subjects get myriad responses.
Maybe it is the mood. Maybe no one has a good answer. Regardless, I generally get questions answered. It is frustrating when they aren't, though.
Sorry, I am of little help. I think supers need to be removed for powdered sugar treatments, though. NOT sure, but I think so.
