Design your own training: Building stones in Horticulture

Design your own course

By designing your own course it is now possible to personalize your own training, where you choose the topics from the list that you would like to have handled. Your goal of the training, the chosen crop, number of participants, their level of education and experience and some additional information will help us to adjust your training to your requirements. Location of the training is in the Netherlands, but may be executed elsewhere in the world as well.

In the menu brief descriptions give a view on the content of the modules. However the focus may be different due to the personalisation. A typical course duration would be three to five days, where tailoring in time is possible too.

Select your building stones below and send to our education department for a program:

1. Introduction and visit Improvement Centre (fixed first building stone when at our facilities)

  • Introduction of program, participants and Delphy
  • Overview greenhouse sector worldwide and the Netherlands; status quo, trends and developments.
  • Field visit: Visit to Improvement Centre, explanation of state-of-the-art greenhouse system and different cultivation systems in the Improvement Centre of Delphy as in introduction to what is to come.


2. Plant = factory (highly recommended as a start)

A plant is a sugar producing factory; how does the plant function and what parts does a plant have? What is the difference between growth and development? The basis of all production is the process of photosynthesis. To have a good understanding more basics of plant physiology are discussed, including the difference between respiration and transpiration.

3. Cultivation systems

Cultivation of many crops can be done in soil or in substrate. Each cultivation system has its own characteristics and in this module we will explore them. What are the advantages and disadvantages of different systems and which systems suits best in your circumstances? This module may include field visits to one or more nurseries depending on the interest of the trainees.

4. Supplemental light

The use of supplemental light has become normal in countries with low light levels during winter. Apart from HPS other systems with LED have become more interest in horticulture. This module explains the use of light, discusses the lamp positions and gives the latest developments in research.

5. Irrigation

Irrigation is of major importance to the plant. It provides water for transportation of nutrients, filling the cells to have their strength (turgor) as well as cooling of the plant. The methods of irrigation as well as a suitable irrigation strategy are discussed during this module.

6. Fertilization

In this module the function of different macro and micro nutrients in the plant is discussed, substrate selection, composition of nutrient solution. For the practical part a calculation of a nutrient solution is done.

7. Climate control

Main reason for placing a greenhouse or other protective structure is to be able to control the climate. But what is an optimal climate for a plant and how to achieve this? This is explained in the lecture Greenhouse Climate. Ventilation, use of screens and heating are part of this module. In addition to the lecture and depending on the group a workshop on the Mollier diagram is added to the program.

8. Crop protection

This module addresses a very important topic: crop protection. Pests and diseases may reduce the potential yield and are important to control. Through scouting pests or diseases are discovered and monitored in the crop. Once the threshold is reached measure should be taken by application of biologic control or application of chemicals. Integrated pest management (IPM) is considered to be the most favourable way of crop protection.

9. Post-harvest

Once the produce is harvested it should reach the consumer in good shape. This module explains what processes are important in keeping the quality in the chain from producer to consumer. This is both relating to plant related processes (e.g. production of ethylene) and logistics. The module may include a visit to a packing station of vegetables or a trader in flowers depending on the interest of the trainees.

10. Propagation

A healthy start of a cultivation is the best guarantee for successful yield. Apart from hygiene the propagation and young plant production is very important in this.  In this module the techniques of sowing and grafting are explained as well as the conditions (climate and fertigation) during the young plant production and hygiene. This module may include a visit to a propagator or breeding company depending on the interest of the trainees.

11. Crop management

Important part of optimisation of the cultivation is crop management. The plant has to reach a balance in production, use and storage of assimilates in order to achieve a maximum yield or the desired specifications. Crop management may include pruning, deleaving, changing temperatures, fertiligation or other conditions. This module explains how this is done and may include practical workshop in the Improvement Centre or a field visit depending on the interest of the trainees.


12. Labour management

This module will address company organisation, production planning and greenhouse labour management. How do you keep your workers motivated, how can you monitor and optimize the labour?
