very carefully :) B's and all ! :) Quickly, gently, and easily,(I hope), relative to the task, :) Stay tuned ! I am interested in your comparisons of comb growth rate by types. Even more so, should they happen to include, screen, and hardware cloth splashed w/ little beeswax, among them :)
p.s. would have been clearer for me to say, "Facilitate management of the same sized combs ...." but I stand by above :)
p.s.s Also interested to know what happens if you seal up the top of that OB hive :) and then : What happens if you quarter the height(thus quadruple surface area of ceiling). But that is for the other thread :)
P.s.s.s Robo - As will I :)
