I'm new to beekeeping and I'm trying one of each type of hive, Lang and TBH (I'm a science teacher and cronic experimenter). I had one of my students build me a TBH I designed based on several websites for his spring shop class project and he did a pretty good job, but the body does not meet the SBB very well. Should I seal the crack along the bottom with something? If so, what would be best? Thanks for the help.
