Energy Use Efficiency of LED Lighting Strategies in Northern Greenhouse Strawberry

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...

Photosynthetic Responses of Lettuce to Different Light Spectra Under Controlled Environment

Lettuce was cultivated under several narrow and broad-band LED spectra to quantify differences in photosynthetic performance and morphology. Gas exchange measurements and chlorophyll fluorescence were recorded throughout the production cycle....

Photoperiod Extension with Narrow-Band LEDs Advances Barley Development

Barley was subjected to photoperiod extension using low-intensity narrow-band LED treatments applied at the end of the natural day. Developmental staging was recorded alongside biomass and tiller counts across the...
