Scientists of the IGZ perform research at two sites. Grossbeeren in the south of Berlin hosts the main site. More research buildings and experimental facilities are located in Erfurt Kühnhausen.
Reopening of the laboratory building
working places in the lab building
working area in the lab building
In the lab building contains besides offices, laboratories with a huge variety of modern technical equipment. This facilitates the performance of experiments on varying scientific topics. In addition to physiological experiments, molecular and different metabolic measurements are feasible. Amongst others, devices for gas and liquid chromatography enable general and spcific detection of primary and secondary metabolites.
Greenhouse B (Cabin greenhouse)
The cabin greenhouse is used to perform experiments on the effect of climate in combination with water and nutrient supply on growth, morphology and physiology of plants and interacting microorganisms. The building contains 16 identical chambers with a ground area of 64m² each. All micrometeorological conditions as well as plant nutrition can be regulated independently. The cabins are equipped with three heating systems, aeration (50% roof area), high pressure air moisturization, CO2-supply, shading and illumination (5klx).
Every 4 cabins are supplied by one common facility for fertilizer composition. Nutrition and water supply occurs by drip irrigation or nutrient solution. All greenhouses are authorized for S1 experiments.

Greenhouse C (Practical greenhouse)
area in all 4 buildings
fertilizer components exactly adjustable
depth of soil in 9 beds
The seperate parts of the practical greenhouse are equipped for detailed investigation of the effect of water and nutrient supply on growth, water and nutrient use efficiency, morphology and physiology of plants.
Ten walk-in growth chambers and 14 reach-in growth chambers enable cultivation of plants under exactly defined environmental conditions.

Greenhouse E ( Gas exchange greenhouse)
environmental gases applicable
above and below ground continuously measurable
and effects on plants reproducible
The gas exchange greenhouse is used to measure the photosynthesis of plants and of microorganisms that are connected to plants, in symbiosis or as competitors. As opposed to conducting measurements on single plants within a set time frame, the gas exchange in this facility is monitored continuously and on large batches of plants. Separate measurements are taken from the upper and lower parts of plants (above ground and below). The facility has eight chambers, all of which can be accessed and controlled individually, which makes it possible to set up the same experiment with different climate conditions, and collect the data without any time delay. It is also possible to introduce air pollutants into the chambers in order to recreate the specific atmosphere of a given city or region and to study the effects of pollutants on plants and microorganisms.
Greenhouse D (Open-sided greenhouse)
The open-sided greenhouse is designed to perform plant trials in small containers that are kept under field conditions. It is used for experiments that need to be conducted without the interference of natural precipitation or birds. Since the sidewalls of this greenhouse are made of wire, the air exchange happens automatically and the roof does not need a separate ventilation system. The facility is equipped with workbenches and connections for potable as well as desalted water.

The IGZ’s library is a public specialized scientific library with information resources in the fields of horticulture and related plant and environmental sciences. Its collection includes approximately 62,000 books and it currently holds subscriptions of 40 journals. The library also provides bibliographic services, document supply services, and literature search services.
