| Popis: | In the winter 2013-2014 Wageningen UR Greenhouse Horticulture conducted studies on energy saving opportunities in the cultivation of gerbera, CV Kimsey. The research was funded by the program Greenhouse as Energy Source from the Ministry of Economic Affairs and LTO Glaskracht. The contribution of LED lighting, LED interlighting, a lower intensity of the light installation, and light integration was investigated. An electricity savings of 45% was the target. By using LED lighting a 20% electricity savings are possible in exchange for a small production loss (2.3%) and some additional heat demand (9%). By installing 80 instead of 100 μmol light gerbera growers can save another 20% energy costing only 3.9% production without sacrificing quality. The targeted PAR sum for light integration was too high to contribute to electricity savings. The use of 20 μmol LED interlighting in combination with 60 μmol top light (LED or SON-T) resulted in significantly less production (9%) and lower flower quality: shorter and lighter, smaller diameter and a lower % of dry matter) than 80 μmol top light. |
