Online course Greenhouse Management Hightech cultivation

green-fingers are not genetically determined but available for everyone

Cultivation in greenhouses is a combination of green-fingers and hightech. To use the technology efficiently, knowledge of plant processes is required. By the correct interpretation of the plant condition, the optimal decisions can be made in climate and water strategy.

During the online course, the individual plant processes will be explained and translated into actions. The course is interactive, in small groups with exercises and discussions everyone is being challenged to practice the theory. After the training every participant will receive a certificate of participation.
