Most likely , it's the multitude of misconceptions, some created by light makers themselves, that have earned LED grow lights such a bad reputation with people who garden indoors. It appears that many LED lighting producers don't grow in the same way as their lights Their management team generally consists of a lighting engineer, plus an entrepreneur with an passion for gardening. The latter has little outdoor gardening experience and if they do, it's not much. They're all about the latest trend in the hopes of making an income, and with little practical gardening experience supporting their claims, they have inadvertently poisoned their market with misinformation. It's fair to say that it's not just the LED experts, and it's not just them. The indoor gardening industry itself has perpetuated these myths out of ignorance. It's easy to accept "facts" about LED grow lights when that same message comes from a variety of reliable sources, like the distributors and magazines that support Hydroponics. It's a lie... lumins don't belong to or for humans! The idea that lumens are a good method to measure the amount of light produced by grow lights is an all-time number-one indoor gardening myth. Measuring light intended for photosynthesis as lumens is simply naive. Let's get it straight: a lumen (scientific symbol:"lm" in science)) is a measurement of the amount of light that our eyes see. It does not, in any way, quantify the light that is the driver of photosynthesis. Period. Simply put, lumens measure the total amount of human visible light that originates from the light source. Plants and humans evolved in the same light that comes through the sun. However, plants and humans use this light in a very different way. Humans are the most receptive to light in the "visible light range" between 400nm and 700nm. But our eyes are focused on between 500 and 600nm, mostly the yellow and green areas that make up the spectrum. Plants have a totally different reaction to light, focusing their absorption on the 400nm-500nm range (blue) as well as 600nm to 700nm (red). They also absorb some light from the rest range of visible wavelengths as well as non-visible light within the infrared and ultraviolet bands. The measurement of grow light output in lumens is a result that is part of the light industry. Since light bulb manufacturers focus mainly on illumination for humans and their lamps, they release their specifications in terms of lumens. Certain countries require that light bulbs are rated according to the output of lumens. Indoor gardeners have adopted this approach for testing the brightness of their garden lighting since it's typically available from the lamp manufacturers (at least up until LEDs entered their scene).
When it comes to lighting your garden, it's a good idea to move beyond lumens and instead think about "photosynthetic photon flux density" (PPFD) that describes the amount of light that can reach an area of. PPFD will be calculated in "micromoles (mmol) per meter2 per second," which is a better measure of the amount of light your plants receive as opposed to lumens. It is necessary to use a quantum flux gauge to determine how much photosynthetically active light energy is actually reaching your plants. When testing LED grow lights, make sure to pick an quantum flux gauge that has been specifically designed for LEDs, or your measurement are likely to be inaccurate. The problem is that these instruments are very expensive. A well-known garden writer published this in one of the most well-known magazines for indoor gardening: "The [high-pressure] sodium light is very red and mimics the fall sun to induce flowering." Hydro shop owners have also claimed that MH lamps are best for vegetative growth because they're "blue" like spring sunlight and HPS lamps are best for flowering because they resemble "red" fall light. The second myth that is popular gardening myth that states that the color of sunlight changes dramatically between seasons and that this color shift causes the flowering. Ask yourself this what happens at midday? Does spring look blue to you or a fall day look red? In a nutshell, no. Light "color" is measured according to the Kelvin (K) scale, with blue being the most prominent color and red being the lowest. The world would appear strange indeed if the light temperature of sunlight changed from one season to the next by any significant amount, even the 2000-2500K difference between HPS and MH lamps. Don't misunderstand: There is the seasonal change in daylight color because of the deepness of the atmosphere which the sun's light must be able to penetrate before reaching earth. The difference isn't huge around 300-500K, depending on the location you live that's not noticeable to the naked eye. On the other hand, daylight color definitely shifts across the duration of a single day. The sun's brightness begins in the morning around 2000K (orange) and then reaches 5000K (white) at midday, then drops back to 2000K or less at sunset. The temperature of the sky during daylight can reach as high as 8,000-10,000K (blue) during a hot summer day.
What is the significance of this? Because gardeners in indoor settings have been taught that changing from "spring blue" to"fall red" will trigger flowering. In which, in turn, causes plants to transition between their growth phases of vegetative and flowering. This may be the consequence of how HID bulbs made their way into indoor gardens. In the beginning, only MH lamps were available, and those who used them experienced outcomes that seemed... acceptable. Later, lamps with HPS were added, and the gardeners who used them discovered that these new lights significantly improved the quality of their harvests. Someone postulated that MH was more beneficial for vegetative growth and HPS more suitable to flower, and the myth became a reality. It's become a popular "fact": pick up any of the magazines available in shops for hydroponics and you'll discover it. But that doesn't mean it's true. Many gardeners use just one type of HID light for their entire garden and that includes HPS, MH and CMH lamps. They don't have any issues "flipping" their gardens from vegetative to flowering/fruiting. They simply altered the photoperiod-the duration for which the lights are turned on. These plants are sensitive daytime flower when their photoperiod is changed, not when the color of the light that they receive changes. Oh how you missed out on the excitement of early days of LED grow lights! When LED grow lights were first introduced, many manufacturers boasted that one 90-watt LED growth light could produce more than 400- or even 600-watt HID. They were laughed at then and are even more laughable today. LED grow light makers are usually overzealous in their claims, which they"prove" by growing lettuce or wheatgrass instead of the more light-hungry plants (e.g. tomatoes, cucumbers or flowers) that indoor gardeners generally prefer.Testing proved that the first "90-watt" units actually drew only 54 to 56 watts of power to the wall on average. With just a few watts being used to cool fans in the onboard unit These lights actually generated less useful light than 75-100 Watts of HPS, but not even close to the 400- or 600-watt HPS performance promised by their manufactures. To gather further details on The Woodlands kindly learn more here. At least the industry seems to have learned their lesson. These days, most LED grow light manufacturers provide accurate power ratings and coverage recommendations for their lights. This combined with better, stronger LEDs and more efficient light designs is aiding in the dismantling of this myth. It would be beneficial for grow light makers using LEDs to publish the power of their light sources in micromoles at set intervals of height so that we, their customers can decide for ourselves what amount of HID these lights could replace under the actual conditions we face when we are in the garden. Because LED emitters have an average life-span of 50,000 hours, which is about 10 years if used 24 hours a day A typical sales pitch includes "This could be the last grow light you'll buy." This is a pitch to help the buyer overcome the expense of buying the LED grow light. It doesn't work that way. Even though LED emitters have an extremely long life span, continuing innovation in the design of light sources like secondary optics, better heat management, and still-better LED emitters coming soon and will force most growers to upgrade to a more modern more efficient light before they've put 10 years on their first LED grow light. While "the last light you'll ever buy" makes for a fantastic sales pitch, don't believe it. This isn't true. The next-most-common sales pitch to sell LED light bulbs is they generate very little or no heat. When a manufacturer states that their LED grow light produces nearly nothing, it can make the experienced gardener wonder whether the company has ever utilized the light for anything other than an image shoot. Yes, LED lights emit less heat than HID grow lights, but there's still heat and it needs to be managed. Take a look: garden temperature will drop immediately after an LED grow light shuts off as it does in the HID garden. Absolutely no heat!
As opposed to other lights that require a lot of cables and use a lot of power, LED lights are more convenient to use and easy to install. The small sizes lights are constructed to be efficient in the sense that they can be used for illuminating any area of your preference. Installing LED lighting in your residential or commercial application will make your home more eco-friendly and reduce your energy costs and more importantly, make you an intelligent owner who keeps up with the latest technological trends. Every lighting technology has certain qualities that determine its characteristics and needs for installation. As with LED lighting. You must be able to think, make a decision and plan precisely in order to have LED fixtures correctly installed in your space. The uses of LEDs are diverse which is why its types and specifications vary depending on the purpose. LEDs work in both dry and wet areas Knowing the right fixture for each can certainly make the installation process simpler. One of the biggest misconceptions about LED grow lighting is that it can't burn plants no matter how close they're situated to the plants. The reason for this is the light's relatively low heat output and the idea "the more photons the better." Early LED grow lights, with their lower output can be placed close to plants-as close as a fluorescent light in certain situations. With modern high-powered LEDs that are able to easily exceed the light-gathering limit for plants. When hung near to plants, LED grow lights can result in photooxidation, also known as "light bleaching." This occurs in the event that more light gets absorbed than can process by plants. The portions of the plant closest to light, often the largest ones, unfortunately, turn in a white color because the chlorophyll has been destroyed. Both HID and LED grow light bulbs can bleach plants if misused, however the issue is less prevalent with HIDs as their high heat output will generally cause the gardener to increase the lighting level, thus removing the possibility of.
