While conventional farming methods still work, they might not be sustainable. New and more efficient techniques such as indoor farming look promising. But this method requires artificial <a href=\"https:\/\/ledask.com\/led-grow-light-vs-hps\/\" target=\"_blank\" rel=\"noreferrer noopener\">lighting<\/a>. Shining red light on plants has proven effective, and we have covered how the light benefits crops in detail below. Take a look!<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"different-kinds-of-light\">Different &#8220;Kinds&#8221; of Light<\/h2>\n\n\n<p>The colors of light get defined by their wavelengths. There is the visible light that forms the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Spectral_color\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">color spectrum<\/a> containing the seven rainbow colors. Longer wavelength light appears red while shorter wavelength light appears violet.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"325\" src=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/1-16.jpg\" alt=\"The visible light spectrum\" class=\"wp-image-380\" srcset=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/1-16.jpg 1000w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/1-16-300x98.jpg 300w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/1-16-768x250.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>The visible light spectrum<\/em><\/p>\n\n\n\n<p>There&#8217;s also the invisible light we cannot see, but the body can feel. Light wavelengths longer than red light (<a href=\"https:\/\/en.wikipedia.org\/wiki\/Infrared\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">infrared<\/a>) warm the body. On the other hand, wavelengths shorter than violet light (<a href=\"https:\/\/en.wikipedia.org\/wiki\/Ultraviolet\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">ultraviolet light<\/a>) cause sunburns.<\/p>\n\n\n\n<p>Plants use these different kinds of light to perform several functions, such as:<\/p>\n\n\n\n<ul><li>Photosynthesis<\/li><li>Deciding when to flower<\/li><li>Determining how large to make their leaves<\/li><li>Deciding which direction to grow and how long to grow their stems<\/li><\/ul>\n\n\n\n<p>However, these functions require different kinds of light. Therefore, farmers need to identify which light type causes specific responses.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"effects-of-color-lights-on-plants\">Effects of Color Lights on Plants<\/h2>\n\n\n<p>Light has multiple colors, and each affects plants in the following ways.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"the-primary-colors\">The Primary Colors<\/h3>\n\n\n<p>The white light spectrum consists of seven primary colors: red, blue, green, yellow, orange, indigo, and violet. Also known as the primary colors of the rainbow, they become visible when a ray of white light gets split by a prism.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"562\" src=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/2-14.jpg\" alt=\"Light dispersion using a prism\" class=\"wp-image-379\" srcset=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/2-14.jpg 1000w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/2-14-300x169.jpg 300w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/2-14-768x432.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>Light dispersion using a prism<\/em><\/p>\n\n\n\n<p>An object usually adopts the color it cannot absorb. Plants cannot absorb the color green, so they evolved to be green. This phenomenon explains why we have green plants.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"red-light\">Red Light<\/h3>\n\n\n<p>Plants are sensitive to red light because they have a red light photoreceptor known as <a href=\"https:\/\/en.wikipedia.org\/wiki\/Phytochrome\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">phytochrome<\/a>. This receptor is a blue-green pigment in plant cells.<\/p>\n\n\n\n<p>Red light makes plants grow large and tall with multiple branches. A large quantity of natural red light can increase meta-tooling production, a hormone that prevents chlorophyll breakdown. Therefore, the plant will stay green during autumn to boost photosynthetic efficiency.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/3-14.jpg\" alt=\"Reddish light on an indoor farm\" class=\"wp-image-378\" srcset=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/3-14.jpg 1000w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/3-14-300x200.jpg 300w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/3-14-768x512.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>Reddish light on an indoor farm<\/em><\/p>\n\n\n\n<p>This light also affects flowering and seed formation. Plants compare the frequency of red and far-red light to decide if it&#8217;s time to begin flowering. You can extend the non-flowering period by exposing the plant to red light.<\/p>\n\n\n\n<p>Lastly, this color can affect the concentration of the special flavor-influencing oils.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"blue-light\">Blue Light<\/h3>\n\n\n<p>Plants sense blue light using a photoreceptor called <a href=\"https:\/\/en.wikipedia.org\/wiki\/Cryptochrome\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">cryptochrome<\/a>. The high availability of bluish light during winter and autumn slows the effect of auxin, a hormone responsible for stem and root growth.<\/p>\n\n\n\n<p>The hormone is also responsible for apical dominance (central stem dominance over other stems). Therefore, blue light causes a short plant height with multiple branches.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/4-14.jpg\" alt=\"Bluish light above leafy veggies in an indoor farm\" class=\"wp-image-377\" srcset=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/4-14.jpg 1000w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/4-14-300x200.jpg 300w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/4-14-768x512.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>Bluish light above leafy veggies in an indoor farm<\/em><\/p>\n\n\n\n<p>Blue light also makes plants open their stomata widely to increase metabolism, which boosts plant growth and development.<\/p>\n\n\n\n<p>Additionally, it makes leaves grow towards the light source and avoids leaf multiplication around fruits. Therefore, a blue light shortage can cause a 20% harvest loss.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"green-light-and-other-colors\">Green Light and Other Colors<\/h3>\n\n\n<p>As stated earlier, plants are hardly sensitive to green light because they lack green light receptors. Therefore, plants grown under green light will be weak and remain young for a long time.<\/p>\n\n\n\n<p>Orange and yellow are closer to red light, while indigo and violet are closer to blue light. Plants react to these colors in the same way they do to red and blue, respectively.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/5-12.jpg\" alt=\"Reddish and bluish lights in an indoor farm\" class=\"wp-image-375\" srcset=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/5-12.jpg 1000w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/5-12-300x200.jpg 300w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/5-12-768x512.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>Reddish and bluish lights in an indoor farm<\/em><\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"invisible-light\">&#8220;Invisible&#8221; Light<\/h3>\n\n\n<p>Invisible light is usually in the form of <a href=\"https:\/\/en.wikipedia.org\/wiki\/Far-red\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">far-red<\/a> and UV. Seeds use the red to far-red light relationship to determine if it&#8217;s time to germinate or not. Also, they use this relationship to determine the number of plants nearby.<\/p>\n\n\n\n<p>Plants take in large amounts of red light while reflecting far-red. Therefore, an area with several plants will have a low red light intensity and high concentrations of far-red radiation.<\/p>\n\n\n\n<p>In such a scenario, seeds will avoid germinating while plants above the surface will shoot faster to emerge above the rest in competition for light.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"942\" height=\"1024\" src=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/6-14-942x1024.jpg\" alt=\"A comparison between far-red and UV light on the light spectrum\" class=\"wp-image-376\" srcset=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/6-14-942x1024.jpg 942w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/6-14-276x300.jpg 276w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/6-14-768x835.jpg 768w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/6-14.jpg 1000w\" sizes=\"(max-width: 942px) 100vw, 942px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>A comparison between far-red and UV light on the light spectrum<\/em><\/p>\n\n\n\n<p>On the other hand, plants perceive UV using the blue light cryptochrome photoreceptor. High UV levels increase the concentration of Anthocyanin, a purple substance that protects plants from UV radiation and micro-organisms.<\/p>\n\n\n\n<p>However, the impact of excess UV light on <a href=\"https:\/\/en.wikipedia.org\/wiki\/Photosynthesis\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">photosynthesis<\/a> is negative. It interrupts the process and damages a plant&#8217;s cell surface membranes &amp; DNA.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"red-light-or-blue-light-for-plants\">Red Light or Blue Light for Plants?<\/h2>\n\n\n<p>As you can see in the section above, red and blue light are the most crucial for photosynthetic activity (plant growth and development). If using artificial light for indoor plants, here&#8217;s how to use the two light colors.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"when-to-use-red-supplemental-light\">When to Use Red Supplemental Light<\/h3>\n\n\n<p>Solar radiation has a high ratio of red light. Therefore, sunlight is ideal for stimulating fruiting, <a href=\"https:\/\/en.wikipedia.org\/wiki\/Chlorophyll_b\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">chlorophyll B<\/a> production, flowering, and increasing the photosynthetic capacity.<\/p>\n\n\n\n<p>However, plants experience lower sunlight levels during winter because there are darker days with shorter daylight hours. You can provide artificial red light plus a full spectrum beam to mimic the solar spectrum to stimulate growth.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"750\" src=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/7-12.jpg\" alt=\"Vegetable farming indoors\" class=\"wp-image-373\" srcset=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/7-12.jpg 1000w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/7-12-300x225.jpg 300w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/7-12-768x576.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>Vegetable farming indoors<\/em><\/p>\n\n\n\n<p>Studies on artificial red light have shown it increases cabbage and tomato biomass. However, overhead artificial red lights alone can cause uneven growth. Therefore, you should combine it with the full spectrum beam.<\/p>\n\n\n<h4 class=\"wp-block-heading\" id=\"artificial-redblue-light-manipulation\">Artificial Red\/Blue Light Manipulation<\/h4>\n\n\n<p>Commercial growers usually manipulate red and blue light to maximize yields. They mix red, purple, and blue light, setting them to specific time schedules to speed up plant growth. However, this optimization is not necessary for houseplants.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/8-9.jpg\" alt=\"A combination of red and blue light in a commercial lettuce farm\" class=\"wp-image-372\" srcset=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/8-9.jpg 1000w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/8-9-300x200.jpg 300w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/8-9-768x512.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>A combination of red and blue light in a commercial lettuce farm<\/em><\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"the-best-way-to-use-red-and-blue-light\">The Best Way to Use Red and Blue Light<\/h3>\n\n\n<p>If running red and blue lights, you should install them in the optimal ratio for the specific plants and their growth phase. A high red to blue ratio is ideal for fruiting\/flowering and increasing plant mass. The inverse is better for leafy veggies or plants requiring stronger stems.<\/p>\n\n\n\n<p>Therefore, you should have customizable controls for red and blue light intensities to optimize plant growth on your indoor farm. These controls will enable high-quality, high-yield farming while reducing production time and costs.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"using-light-to-make-better-plants\">Using Light to Make Better Plants<\/h2>\n\n\n<p><a href=\"https:\/\/en.wikipedia.org\/wiki\/Sunlight\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Solar radiation<\/a> from natural light works well for plants. But it contains some light frequencies that provide no benefits. Therefore, you can use artificial light with the required frequencies to make plants grow better.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"why-intensity-matters\">Why Intensity Matters<\/h3>\n\n\n<p>Giving plants the light color they need is one thing. Providing it in the required light intensity is another. Outdoor plants naturally get light from the sun, which comes in as high-intensity light. Therefore, you can&#8217;t place any blue or red light bulb in a grow room. The light must provide enough photons to support and enhance photosynthetic efficiency.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/9-8.jpg\" alt=\"Light measurement in an indoor farm\" class=\"wp-image-371\" srcset=\"https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/9-8.jpg 1000w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/9-8-300x200.jpg 300w, https:\/\/ledask.com\/wp-content\/uploads\/2022\/08\/9-8-768x512.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><em>Light measurement in an indoor farm<\/em><\/p>\n\n\n\n<p>Thus, you should consider a variable called PPFD (Photosynthetic Photon Flux Density) to determine the best light for your indoor farm. This unit (expressed in &#xB5;mol\/m<sup>2<\/sup>\/s) shows the PAR (amount of usable light) reaching your plant from a grow light.<\/p>\n\n\n\n<p>Flowering plants require 300-600 &#xB5;mol\/m<sup>2<\/sup>\/s in the vegetative phase and 800-1000 &#xB5;mol\/m<sup>2<\/sup>\/s when flowering.
