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....

Daily Light Integral Requirements for Uniform Tomato Seedling Propagation

Tomato seedlings were propagated across a range of daily light integrals to establish targets for uniform, transplant-ready material. Growth uniformity was assessed using stem diameter, hypocotyl length and dry weight...
