Re: Moving from ok queens . . . to great queens.
G. M. Doolittle in Scientific Queen Rearing is where I first heard of this method. He claimed that for queenless cell builders, this method of leaving them larva to feed three days before introducing grafts would produce cells every bit as good as natural swarm cells. I myself came up with 4 days, it just sounded like a good time as cells are one day from being capped over.
