I have just received my complete Flow hive and I am waiting for my bees! super excited. I just have a question about interframes and I thought you might have a take on it.
The brood box contains 8 langstroth frames, and a beekeeper told me there was way too much room for the frames to move around and that it was better to add an interframe, what do you think? he also told me that the bees were going to building around this empty spaces everywhere, he event said it would be good to add a 9th frame to fill that empty space.
