I started my first hive this summer and already know that I will be involved with bees the rest of my life. I plan to build five hives this winter. I've downloaded several sets of plans. Here's the question: I don't plan on moving any of these hives once they are placed in the spring. So, would it be better to build the new ones with 2 X 12 lumber since weight isn't an issue? It seems that the thicker lumber would provide better insulation in both summer and winter. Of course, I would build the tops out of something lighter. Comments?
