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.<\/span><\/p>\n<h3><span style=\"color: #193330;\">Conclusions<\/span><\/h3>\n<ul>\n<li><span style=\"color: #193330;\">By including far-red in the growth spectrum, the PPE is<\/span><br \/><span style=\"color: #193330;\">reduced.<\/span><\/li>\n<li><span style=\"color: #193330;\">Plants grown with FR spectrum was larger in size and had higher biomass than the ones grown under the \u201cPAR\u201d spectrum.<\/span><\/li>\n<li><span style=\"color: #193330;\">The growth efficacy in the crop where higher in the FR spectrum, even though the lower PPE.<\/span><\/li>\n<li><span style=\"color: #193330;\">These results indicated that PPE of a grow light is not an accurate way of describing performance if the spectrum.<\/span><\/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\"  id=\"row-691151800\">\n\n\n\t<div id=\"col-1209757564\" class=\"col small-12 large-12\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n\n\t<div id=\"gap-1434903603\" class=\"gap-element clearfix\" style=\"display:block; height:auto;\">\n\t\t\n<style>\n#gap-1434903603 {\n  padding-top: 30px;\n}\n<\/style>\n\t<\/div>\n\t\n\n\t<div id=\"text-3568467306\" class=\"text\">\n\t\t\n\n<h2>Gerelateerde inhoud<\/h2>\n\t\t\n<style>\n#text-3568467306 {\n  text-align: center;\n}\n<\/style>\n\t<\/div>\n\t\n<div class=\"row\"  id=\"row-1836978689\">\n\n\n\t<div id=\"col-50061039\" class=\"col small-12 large-12\"  >\n\t\t\t\t<div class=\"col-inner\"  >\n\t\t\t\n\t\t\t\n\n\t<div id=\"gap-1832814125\" class=\"gap-element clearfix\" style=\"display:block; height:auto;\">\n\t\t\n<style>\n#gap-1832814125 {\n  padding-top: 30px;\n}\n<\/style>\n\t<\/div>\n\t\n\n\n  \n    <div class=\"row gradient-posts large-columns-3 medium-columns-1 small-columns-1\" >\n  <div class=\"col post-item\" >\n\t\t\t<div class=\"col-inner\">\n\t\t\t\t<div class=\"box box-overlay dark box-text-bottom box-blog-post has-hover\">\n            \t\t\t\t\t<div class=\"box-image\" style=\"border-radius:2%;\">\n  \t\t\t\t\t\t<div class=\"image-cover\" style=\"padding-top:102%;\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/heliospectra.com\/nl\/blog\/greenhouse-lighting-strategies-for-vegetable-transplant\/\" class=\"plain\" aria-label=\"Strategie\u00ebn voor kasverlichting bij het verplanten en afwerken van groenten\">\n\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1632\" height=\"1224\" src=\"https:\/\/heliospectra.com\/wp-content\/uploads\/2023\/05\/5ef8b3d80f5e290eba3554d5_Greenbelt-Greenhouse_Operations.jpeg\" class=\"attachment-original size-original wp-post-image\" alt=\"Elixia led kweeklampen bij Greenbelt Greenhouse\" srcset=\"https:\/\/heliospectra.com\/wp-content\/uploads\/2023\/05\/5ef8b3d80f5e290eba3554d5_Greenbelt-Greenhouse_Operations.jpeg 1632w, https:\/\/heliospectra.com\/wp-content\/uploads\/2023\/05\/5ef8b3d80f5e290eba3554d5_Greenbelt-Greenhouse_Operations-300x225.jpeg 300w, https:\/\/heliospectra.com\/wp-content\/uploads\/2023\/05\/5ef8b3d80f5e290eba3554d5_Greenbelt-Greenhouse_Operations-1024x768.jpeg 1024w, https:\/\/heliospectra.com\/wp-content\/uploads\/2023\/05\/5ef8b3d80f5e290eba3554d5_Greenbelt-Greenhouse_Operations-768x576.jpeg 768w, https:\/\/heliospectra.com\/wp-content\/uploads\/2023\/05\/5ef8b3d80f5e290eba3554d5_Greenbelt-Greenhouse_Operations-1536x1152.jpeg 1536w\" sizes=\"auto, (max-width: 1632px) 100vw, 1632px\" \/>\t\t\t\t\t\t\t<\/a>\n  \t\t\t\t\t\t\t<div class=\"overlay\" style=\"background-color: rgba(0,0,0,.25)\"><\/div>  \t\t\t\t\t\t\t  \t\t\t\t\t\t<\/div>\n  \t\t\t\t\t\t  \t\t\t\t\t<\/div>\n          \t\t\t\t\t<div class=\"box-text text-left is-large\" >\n\t\t\t\t\t<div class=\"box-text-inner blog-post-inner\">\n\n\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t<h5 class=\"post-title is-large\">\n\t\t\t\t\t\t<a href=\"https:\/\/heliospectra.com\/nl\/blog\/greenhouse-lighting-strategies-for-vegetable-transplant\/\" class=\"plain\">Strategie\u00ebn voor kasverlichting bij het verplanten en afwerken van groenten<\/a>\n\t\t\t\t\t<\/h5>\n\t\t\t\t\t\t\t\t\t\t<div class=\"is-divider\"><\/div>\n\t\t\t\t\t\t\t\t\t\t<p class=\"from_the_blog_excerpt\">\n\t\t\t\t\t\tGrowing lettuce, herbs and vegetables in your greenhouse?
