This is Primal Bee, the hive with giant frames

Primal Bee is an impressive hive that focuses on giant frames in the brood chamber. With these large frames, it aims to better utilize the thermodynamic potential of the colony. In the recent edition of Apimondia, one of the most surprising innovations was a hive model called Primal Bee, characterized by its brood chamber equipped with eight enormous frames nearly 65 centimeters tall. These frames, which triple the height of a standard Langstroth frame, are designed to maximize the thermodynamic characteristics of the hive.
