Course Information

This course is targeting on growers and farm managers who want to improve their (lighted) production in the months with lower sun light amounts. From the past we have learned that this course is very interesting for vegetable growers who invested already or are planning to invest in artificial light above or in between their crop. Course is focussing on lighted production of greenhouse tomato. The course contains a balanced mix of (plant physiological) theory combined with useful tools and practical illustrations. Of course there is enough room for personal questions and discussion within an international group of participants. Every course day is also illustrated with some field visits.

Course Program

Day 1: Light and Plant

• Calculating with light: What is lux, joule, micromole and watt? What do they express and how can you calculate with them. What is grow light? Diffences in light spectra and colours of SON-T, LED and sun light.
• Relation Light, CO2, temperature and Plant growth: effect of these keyfactors on plant growth and photosynthesis. Relation light intensity and volume on photosynthesis and Leaf Area Index. Influence day length on plant growth and plant balance.

Day 2: Greenhouse climate and lighted crops

• Influence of artificial light on greenhouse climate: Influence lamp heat and outside climate on screening strategy, greenhouse climate and plant temperature.
• Optimizing climate control in artificial lighted winter crops: How to use artificial lighting in combination with heating system. Set points for lighting, heating, venting and dehumidification.
• Optimizing plant growth: Relation plant age and plant balance with plant growth speed. Crop evaporation in relation to set points air humidity, temperature and CO2.

Day 3:

• Greenhouse installations: Investment in LED, SON-T or hybrid-lighting concepts? Lamp type and position. Light interception in relation to row distance and plant density.
• Different light levels and concepts suitable for different areas and climate zones
• Cultivation systems and production planning: Interplanting or mono-crops, (dis-) advantages of both systems. Optimal cultivation length.
• Cultivation strategy: Monitoring and control of production and quality. Optimizing plant density and plant load in winter months. (Lighted) crops in relation to pest management, how to control insects, fungi, bacteria and viruses?

 Every day, above mentioned themes will be illustrated with field visits.

Target group, trainers and maximum amount of trainees
