Welcome to the forum. I do have a tbh but it has frames. I had built the tbh and a guy in the club I'm in gave me some bees in a tbh nuc. I hadn't opened them until I got them home and they had built their comb on the sides none on the bars. I built frames on my topbars where I could tie the comb in. Since I need a few done that way when ahead a did the entire hive. Works pretty good. On you planting flowering plants, I have also, but they range huge areas. Good luck with your bees.
