LED grow lights, often optimized for plant growth, might not excel in photosynthetic photon efficacy (PPE) due to variations in LED colors. For instance, far-red (FR) light (700-800 nm) enhances plant development but is not counted in PPE calculations. We aim to compare the overall growth efficacy (g\/kWh) between plant-optimized spectrum and high-PPE spectrum LED lights.<\/p>\n<h3>Conclusions<\/h3>\n<ul>\n<li>By including far-red in the growth spectrum, the PPE is<br>reduced.<\/li>\n<li>Plants grown with FR spectrum was larger in size and had higher biomass than the ones grown under the \u201cPAR\u201d spectrum.<\/li>\n<li>The growth efficacy in the crop where higher in the FR spectrum, even though the lower PPE.<\/li>\n<li>These results indicated that PPE of a grow light is not an accurate way of describing performance if the spectrum.<\/li>\n<\/ul>\n\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n\n<\/div>\n<div class=\"is-divider divider clearfix\" style=\"max-width:100%;height:1px;\"><\/div>\n\n<div class=\"row\"
