The chimney allows you to respect certain limitations that are present in urban centers in terms of distances to be maintained. If you have the possibility to place it more than 5 meters from a neighbor or if you have a divider (bush, wall ect…) more than 2 meters high, you can install it without a chimney. The use of the latter can reduce the amount of honey produced as more energy is needed to leave the B-BOX to go and forage for flowers.
