This measurement adopted by the International System of Unit is used to <strong>know the total amount of visible light emitted by a bulb or light source<\/strong>. Therefore, the more lumens, the greater the brightness power it will provide. It is useful to measure <strong>luminous efficiency<\/strong>, which is the ratio of lumens to power used (lm\/W).<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"450\" src=\"https:\/\/www.growbarato.net\/blog\/wp-content\/uploads\/2024\/07\/lumens-indoor-crop.jpg\" alt=\"lumens indoor crop\" class=\"wp-image-171966\" srcset=\"https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2024\/07\/lumens-indoor-crop.jpg 1000w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2024\/07\/lumens-indoor-crop-300x135.jpg 300w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2024\/07\/lumens-indoor-crop-768x346.jpg 768w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n<\/div>\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_is_a_lux\"><\/span>What is a lux?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>This concept is closely linked to that of lumen, as<strong> it relates the light emitted to the surface area it covers<\/strong>. In other words, it is the same amount of light measured by lumens but projected onto a surface. For this reason, lux can be considered to be one lumen per square meter.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Difference_between_lux_and_lumen\"><\/span>Difference between lux and lumen<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>In short, the main difference is that the<strong> lux measures the intensity of light on<\/strong> <strong>a surface<\/strong>, while the lumen does not take into account the distance or the space that is illuminated. To measure these characteristics in a room or grow room you can use tools such as a lux meter.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"450\" src=\"https:\/\/www.growbarato.net\/blog\/wp-content\/uploads\/2024\/07\/lux-cannabis-plants.jpg\" alt=\"lux meter cannabis \" class=\"wp-image-171971\" srcset=\"https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2024\/07\/lux-cannabis-plants.jpg 1000w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2024\/07\/lux-cannabis-plants-300x135.jpg 300w, https:\/\/www.gbthegreenbrand.com\/blog\/wp-content\/uploads\/2024\/07\/lux-cannabis-plants-768x346.jpg 768w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_is_a_lux_meter_for\"><\/span>What is a lux meter for?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>If you want to achieve a healthy crop and good harvests, one of the things to consider is <strong>how to measure and optimize the amount of light<\/strong> in the grow room to increase yields. The <a href=\"https:\/\/www.gbthegreenbrand.com\/components-and-accessories\/565-luxmeter-light-intensity-lumens.html\">luxmeter<\/a> allows you to measure the intensity of illumination. The unit of measurement it uses is lux, so it will indicate the number of lumens per square meter.<\/p>\n\n\n\n<p><strong>How many lumens are needed for indoor cannabis growing?<\/strong><\/p>\n\n\n\n<p>The amount of light needed by <strong>cannabis plants<\/strong> <strong>varies depending on the stage they are in.<\/strong> Therefore, it should be kept in mind that seedlings do not absorb much light, but <strong>during the growth phase they need all the light they can get<\/strong>. The same applies during the flowering phase, when it must be ensured that the buds will be as large as possible. For this purpose, a chart has been drawn up with the recommended lumens per square meter.<\/p>\n\n\n\n<figure class=\"wp-block-table aligncenter\"><table><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Phase<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\"><strong>Lux (lm\/m\u00b2)<\/strong><\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Cuttings\/young plants<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\">5.000 \u2013 10.000 lx<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Growing<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\">15.000 \u2013 50.000 lx<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Flowering<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\">50.000-75.000 lx<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>The <strong>maximum recommended amount<\/strong> is 75,000 lx. Exceeding this limit can cause light stress in plants and above 80,000 lux increases the risk of bleaching. Raising the light more than recommended will <strong>decrease the yield.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Types_of_light_for_crops\"><\/span>Types of light for crops<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>In addition to intensity, the <strong>type of lighting<\/strong> being used is also important. Thus, during rooting and the first stages of seedling growth it is recommended to opt for a blue light, such as <strong>CFLs or fluorescent<\/strong>. With the same spectrum, in many cases we switch to HM bulbs, allowing them to grow strong and prepare for flowering. During the generative phase, it is recommended to use a red spectrum, imitating that of natural light, being able to use a HPS. However, thanks to innovations in <a href=\"https:\/\/www.gbthegreenbrand.com\/130-led-lighting\">LED lighting for cannabis growing<\/a>, nowadays these lights can cover the whole cycle, due to their full spectrum.<\/p>\n\n\n\n<p>[ppgbo products=&#8221;6885,5693,7144&#8243; language=&#8221;en&#8221;]<\/p>\n\n\n\n<p>There is a relationship between the different types of lights and lumens.
