Chapter 7 Greenhouse production systems & Hydroponics
7.2 Instructions
- Please watch both videos carefully to get a general introduction into greenhouse production systems. The videos are the basis for further discussion in the inverted classroom.
- Pay special attention to the equipment and infrastructure of a greenhouse. We will start the week with a visit of a greenhouse at the institute to discuss and compare the information given in the videos with a real situation. A special emphasis will be given to “light” and “lighting.”
- Following questions may help you for preparation:
- How is light in a greenhouse different from the field and what does it mean for plant cultivation?
- How are light and lighting affecting plant yield and produce quality in a greenhouse?
- How can the lighting be adapted to the needs of the plants?
- How can light and lighting be modified (management strategies, infrastructure)?
- What is the meaning of UV-light and far red light?
- How is light in a greenhouse different from the field and what does it mean for plant cultivation?
- You will find further readings on light (especially LED) and lighting on eCampus.
7.3 Literature for discussion
Paper discussion: We will discuss the article “Agricultural sustainability estimation of the European photovoltaic greenhouses” (see eCampus). Energy consumption is a major challenge in horticultural production. Especially in greenhouses we need energy for heating, cooling, climate control (e.g. ventilation), fertigation system, and lighting. This article is on the possible combination of photovoltaic in greenhouses. On eCampus you will find further readings on this topic.
7.4 Term paper topics
- Lighting in greenhouses. How can lighting be used to improve plant performance, yield, and produce quality
- Sustainability of Greenhouses or Greenhouse Production Systems
