However, the treatment that really provided the most intense coloration was a combination of red and blue at 100 micromoles.\u201d\u00a0\u00a0<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;201341983&quot;:0,&quot;335551550&quot;:1,&quot;335551620&quot;:1,&quot;335559738&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p style=\"text-align: left;\"><span data-contrast=\"none\">He continued, \u201cEven within five days, we see [in the images above] that the crop obviously looks much better than the control. So, our conclusion is that anywhere from five to seven days of the end of production supplemental lighting at 100 micromoles promotes the red pigmentation of lettuce. This is becoming used throughout the world in terms of enhancing color with lettuce when you have relatively low daily light integrals.\u201d\u00a0\u00a0<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;201341983&quot;:0,&quot;335551550&quot;:1,&quot;335551620&quot;:1,&quot;335559738&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p style=\"text-align: left;\"><span data-contrast=\"none\">LED grow lights provide today\u2019s growers with the ability to customize spectrums of light to fit various plant growth applications.
