wadehump - thank you. My four hives are built on deeps with small cell. (except for 4 regular size frames in two hives that came with two nucs) Above that I run medium supers and they are a mixture of small cell and foundationless. This year was an experiment with the foundationless and I feel its been a great success so want to continue to move in that direction. My dilemma is how to change out the foundation in the deep supers for foundationless frames. Any ideas on how to do that?
