February 19-20, 2015
The University of Arizona - CEAC
This symposium is organized by the University of Arizona Controlled Environment Agriculture Center (CEAC) in conjunction with the USDA SCRI (Specialty Crop Research Initiative) LED project members from Purdue University, University of Arizona, Michigan State University, Rutgers University and industry partner Orbitec. The symposium will provide SCRI LED project members and other nationally recognized research groups the opportunity to bring the latest information, understanding, and assessments of the use of LEDs in horticulture through oral presentations
Three major topics covered in this symposium will be:
1. Plant responses under sole-source LED lighting,
2. Plant responses under supplemental (high intensity) or photoperiodic (low intensity) LED lighting in greenhouses, and
3. LED technology development, evaluation, and economics.
