This study compared several supplemental lighting strategies for greenhouse strawberry at northern latitudes on an energy efficiency basis. Yield, marketable quality and electricity consumption were tracked across a full winter...
Supplemental far-red radiation was applied to greenhouse tomato during the winter production season to assess morphological and yield responses. Treated plants exhibited longer internodes and larger individual leaves compared with...
This experiment tested whether root zone temperature modifies the crop response to light spectrum in hydroponic lettuce. A factorial design combined three nutrient solution temperatures with three spectral treatments. Significant...
