BeNeLuxSHS 2015 Symposium: Plant control by LED light

Annual Symposium: Thursday 15 October, 2015
Forum building, Droevendaalsesteeg 2, Wageningen, The Netherlands

LEDs provide exciting new 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 in greenhouses will increase exponentially. Different forms of city farming such as  plant factories or vertical farming attract a lot of attention. Many city farm initiatives pop up around the world. All these systems have in common that they want a full control of the production of horticultural crops by the use of LED lighting.

The 2015 annual symposium of the Benelux Society for Horticultural Science will include presentations from several researchers active in the Benelux. They will present the latest insights on control of plant production by LED light. There will also be an extensive discussion on city farm and the use of LEDs therein.

This symposium is open to everyone who is interested in the use of LED lighting for production of plants in horticulture. We expect that a nice mix of researchers, advisors  and private companies will participate.

The symposium is organised by Wageningen University (Chair Group Horticulture and Product Physiology) and the Campus of Wageningen UR is the location for this meeting.
We expect many people to participate, while the number of symposium participants has limits. So don’t wait too long with registration. The registration fee is 30 euro for students and members of BeNeLux SHS; for others the fee is 45 euro. Lunch is included in the fee.
