October 19, Wageningen:

Wageningen University organizes special LED Light Plant Control symposium

Wageningen University & Research is organising a one-day symposium on ‘Plant control by LED Light, on Thursday 19 October 2017 in Wageningen, the Netherlands.

LEDs provide exciting possibilities to modulate spectrum and direction of light, to control instantaneously light intensity, and to decouple lighting from heating. This allows not only to control growth, development and yield of plants, but also to control quality, disease resistance and last but not least to save energy.

Several growers have already installed LEDs in their greenhouses and it is assumed that the coming years the use of LEDs will increase exponentially. Many vertical farming initiatives pop up around the world. All these systems have in common that they want full control of the production of horticultural crops by the use of LED lighting.

After a successful one-day symposium in 2015 about Plant control by LED light, WUR got many requests to organise a next version of this symposium. The 2017 symposium will include presentations from several researchers from universities and research organisations. They will present the latest insights from scientific research on control of plant production by LED light. There will also be an extensive discussion with companies active in city farming.

This symposium is open to everyone who is interested in the use of LED lighting for production of plants in horticulture. WUR expects that a nice mix of researchers, advisors and private companies will participate and that it will be a good place for networking.

The maximum capacity of participants is 225. So don’t wait too long with registration.
