Optimizing LED lighting spectra for enhanced growth in controlled-environment vertical farms.

ABSTRACT: Due to growing demands for sustainable food production, controlled-environment vertical farms (CEVFs) have emerged as promising systems for cultivating vegetables and herbs in urban areas. However, these systems are often criticized for their high energy consumption, largely influenced by artificial lighting. This study aimed to optimize white LED-based lighting by supplementing it with additional deep red (DR, 660 nm) and far red (FR, 730 nm) light, evaluating effects on the growth of lettuce (Lactuca sativa cv. Batavia-Caipira) and basil (Ocimum basilicum cv. Emily). Five treatments were tested, all using a white LED base spectrum (with blue, green, and red components), with varying levels of DR and FR. In one treatment, light intensity (PPFD) was doubled to 244 µmol·m^⁻2·s
