Áhrif LED topplýsingar á forræktun tómata, agúrku og papriku : final report

Abstract

In Iceland, winter production of greenhouse crops is totally dependent on supplementary lighting and has the potential to extend seasonal limits and replace imports during the winter months. Adequate guidelines for lighting under LEDs are not yet in place for transplant production of tomatoes, sweet pepper and cucumbers and need to be developed. The objective of this study was to test if the light source is affecting growth and quality of seedlings and if light related costs can be decreased by the selection of the light source.
