Vertical farming is an important topic for the future, both globally and at ebm-papst. This is why this year’s trainees at St. Georgen and Mulfingen are working on the “ebm-papst Indoor Farm” project.
Jessica Hund from Product Management for Compact Air Technology in St. Georgen came up with the idea, “We can tell customers a lot about our expertise and products in the field of vertical farming. But it’s better if we show it in practice.”
An exciting challenge for mechatronics engineers and electronic engineers in training: they researched and built everything themselves, from the composition of the nutrient solution and monitoring and evaluating temperature and humidity to harvesting plants. It’s a success story for trainees and ebm-papst, who benefit equally from dealing with a hot topic.
The indoor farm is a glass cube, which now sprouts herbs without earth and without watering. Special LED strips ensure the necessary light, an automated control system regularly supplies the plants with a sophisticated nutrient solution: in theory, nobody has to look after the small farm in the cube.

Fresh vegetables for the canteen
Here, everything grows and thrives on its own under perfectly balanced conditions. This means that there are no pests, no overwatering, and always some tasty parsley or chives to hand. The canteen boss, who will be able to serve the herbs from the indoor farm in the future, is not the only one who is pleased about this.
The 108 x 48 x 174 cm cube contains four AxiRev 126 compact fans that ensure fresh and pleasant air. A BCI gear motor delivers the necessary power for the hose pump, which pumps the nutrient solution to the plant roots every three hours.
They fill with nutrients for 15 minutes, then the liquid is pumped out and filtered, which is called a hydroponic system. The result obtained in just under two months is all the more impressive.
As the indoor farm is mobile, it will travel to trade fairs in the future and show that vertical farming is no longer a dream of the future.
