The Langstroth unit – three deep boxes, floor, and roof – was used from the start – in 1990 - in our own apiary as it is also common practice amongst bee farmers all over the world. Boxes and frames can be easily interchanged as required. The number of frames to be handled is reduced, a queen excluder can be inserted at the end of the main honey season, if at all. Only too frequently a queen excluder also acts as a honey excluder.
Running your bees on full depth frames throughout is a common practice amongst bee farmers as it reduces the number of frames to be handled and is significantly more economical - more bees and honey for the same outlay on hive and frames compared to a conventional hive using shallow supers.
