PRODUCTION - 06 December 2022, Saxony-Anhalt, Magdeburg: Light burns after sunset in the entrance area of the "Gruson greenhouses". The palm house can be seen above it. The darkness there is created by the dense vegetation inside. In front of it is a winter bare tree. The Gruson greenhouses had undergone extensive renovations in recent years and had just reopened to visitors about a year ago on November 11, 2021. The greenhouses had single glazing replaced with double glazing and a rainwater cistern connected to the water system. In addition, the plantings in the greenhouses were sorted so that a lower temperature can prevail in the "Dry Subtropics" greenhouse than in the Palm House, for example.
