Hi all
Recent posts in this thread have missed one point... The smoothness of a
follower board (dummy frame) allows air to be moved by convection where a
much lower temperature difference occurs.
I have built experimental hives with walls that are a sandwich consisting of
6 mm ply
open single bee space
6 mm ply
remarkable air convection currents are set up by very small amounts of
insolation because the outermost wall is so thin.
