This is my first foray into bees and top bar hives and I need the benefit of someone's wisdom.
I built my TBH without a mesh floor. I couldn't find mesh that I thought was the right size, package of bees was coming...I screwed the floor right to the bottom of the hive which probably isn't the end of the world but I'm concerned about ventilation with summer coming. I realize there are other reasons to have a mesh floor and having found some mesh that I like I might try and go back and remove the bottom board and install the mesh but that will be a process since my hive is sitting with the bottom board resting on the legs.
I have 3x1" entrance holes in the middle of the hive on the side. The bees quickly filled in about two thirds of the two holes I left open with propolis so I left the third corked. Where is the best place for a ventilation opening and how large should it be? I was thinking higher up on the side opposite the entrance holes.
I'm in Colorado where the relative humidity will hover at a muggy 30 - 40% for most of the summer.
