Horticulture lighting

Basics in lighting for greenhouses and vertical farming.

Our seminar focuses on light for horticulture. The current topic »vertical farming« presents new challenges for lighting. Lighting designers have to know how different spectra and light intensities influence the plant processes. Which kind of light causes flower induction, flower prevention, chances for propagation and breeding? Besides these questions we will cover aspects of efficiency and energy input calculations. Since we are free of obligation to any manufacturer, questions about products and trends are answered honestly with no holds barred.

We give insights into the latest findings of the BrightBox project, Venlo. You will experience practical workshops and amazing demonstrations in the seminar. Afterwards you will have a well-founded basic knowledge in the field of plant illumination. You will also have the opportunity to carry out optional dimensioning of greenhouse lighting in the professional lighting design tool DIALux evo on the third day.

Content

Overview of the seminar.

Day 1

  • History and developments of vertical farming world-wide
  • Plant processess: transpiration, respiration and photosynthese
  • Influencing factors and how they influence the plant processes
  • Experiencing and measuring light: light for humans, light for plants, different light sources
  • Influence of different spectra:
    blue-red versus full spectrum LED, dimmable LED, LEP (light emitting plasma)
  • Light for plants: wavelength, quantity, daylength
  • Effect of lights on total climate
  • Light/temperature relation

Day 2

  • Effect of cultivar choice and light
  • Climate recipe: Basil, lettuce and Coriander
  • Calculations for vertical farms
  • Efficiency of lights, energy input calculations for different light recipes
  • Solarcells on rooftops of farms
  • Calculation of electricity costs, investments and running costs
  • Business models
  • Seeds, substrates, fertilizers, water, pots and systems
  • Some simple measurements to demonstrate what happens in systems and how to manage
  • Practical examples of what light recipes can do
  • Flower induction, flower prevention, chances for propagation and breeding

Day 3 (DIALux evo as an option)

  • User interface of the software
  • Construction of greenhouses / vertical farms
  • Standard objects and reflectance factors
  • Photometric file formats: IES / LDT / ULD
  • Handling the plug-ins (luminaire catalogues)
  • Selection and placement of luminaires
  • Use of calculation surfaces
  • Calculation and results overview
  • Conversion of illuminance to micromole with the help of Excel
