Talking about LED grow lights, what is the most reminiscent of them? Maybe a lamp is covered with LED diodes of different colors, of which white color diodes occupies most of the area and emits pinkish white light. Then it is equipped with a simple knob for easy adjustment of light and dark. This is the most popular full-spectrum grow light on the current market, which can provide plants with comprehensive light nutrition. Now, in 2022, the latest LED grow light technology is a combination of full-spectrum LED diode and intelligent technology: In terms of lighting technology, it has evolved from full-spectrum lamps composed of multiple colors to full-spectrum LED diode. In other words, each LED diode has the same spectrum. The light emitted from the lamp, each beam is the same. It overcomes the weakness of narrow LED band, so that the plant phototrophic absorption under the lamp will not be affected by the arrangement position of different color diodes, and has a much better consistency. In terms of control technology, it relies on the increasingly mature and widely promoted smart home appliance technology. The smart plant light technology that used to only appear in large-scale planting farms can already be applied to individual or small-scale growers. Adding an intelligent control module to the plant light, through a simple APP interface operation, without redundant mechanical buttons or knobs, the plant light can realize automatic functions such as spectral changes, light intensity changes, and switching lights. Help all growers save time and grow more efficiently. No matter what kind of plants growers are growing, such a light can provide the right spectrum and lighting strategy. Another great thing about intelligence is the group control, which means that one light can also be controlled in groups by connecting multiple lights to adjust the scale anytime, anywhere. Similarly, other products of the smart platform, such as humidifiers and sensors, can also be linked to form a complete smart farm. This is the latest development of plant light technology in 2022, and it is also the future trend. For example, this smart LED grow light below is the representative of a new generation of LED grow light. https://www.bossgoo.com/product-detail/patented-uniformtity-technology-grow-lights-61942660.html

Cannabis grows and develops differently to different spectral colors. One of the most critical factors in cannabis cultivation is light, but light has different colors, which specific wavelengths of light can be used to obtain satisfactory cannabis? According to the current research, the main role is the following. UV: The effects of UV light on cannabinoids were first presented in an academic paper by Lydon et al. 1987. Lydon and his team concluded that UVB increased floral THC concentrations. UVB has strong radiation and can easily cause damage to plants and growers. But UV light works by stressing the plant, which defends and produces more THC. Therefore, relatively mild UVA can have the same effect. Even UVA needs to control the amount of use, that is, the lighting time, to avoid damage caused by prolonged exposure. Blue light: Studies have shown that blue light also has a positive effect on the increase in THC concentration. Blue light has been shown to increase the concentration of cannabinoids, especially THC, as demonstrated in the article by Magagnini et al. 2018. This is the first article to compare the differences between LEDs and HPS in cannabis growth and flower quality. At the same time, blue light will also enhance the compactness of the plant and make the plant denser, preventing the plant from being too long to support large flowers. This is also why traditionally, people like to use MH lamps during the growth phase of cannabis because of the strong blue light in its spectrum. Green light: Green can effectively penetrate the leaf layer. In contrast, red and blue light are almost completely absorbed by the first leaf layer. Therefore, the lower leaf layers can utilize green light in photosynthesis and also produce yield as well. Appropriately adding green light to the plant lamp makes the color of the lamp look more normal, which is beneficial for the grower to observe the plants during the planting process and find out diseases, insect pests or other problems in time. Red light(deep red 660nm): As we all know, the utilization efficiency of red in photosynthesis is very high. For cannabis, it is more important to control the ratio of red to far-red, which has important effects on plant morphology and even flowering and germination. Cannabis plants become taller under low R:FR ratio conditions (Magagnini et al., 2018). This can be detected very early by stem and petiole elongation (Figure 3). Elongated plants that do not receive enough red light are weaker relative to far-red light and therefore cannot carry high yields. Far red light: American cannabis cultivation expert DR rugbee has demonstrated the importance of far red for plants and cannabis. Far red plays an important role in plant morphology and flowering. The key is to control the amount used and when. Too much far red will cause the plant to grow too long during the growing stage, resulting in no large flowers. The addition of far red in the flowering stage and the use of end-of-day treatments can speed up flowering and improve yield. Spectra rich in far red are more suitable for mother plant cultivation for longer cuttings because of the ability of far red to make plants grow longer. How to choose the best spectrum for cannabis cultivation? Is it not important except for the wavelengths of light mentioned above? In fact, it is not. Many studies have also shown that although other light is not as efficient as the light mentioned above, it has a synergistic effect and improves the overall photosynthetic efficiency. So it's wise to choose a spectrum that includes all wavelengths from UV to far-red, but keep in mind that well-balanced ratios give the best growth results. On the other hand, the optimal ratio varies according to different cannabis varieties and growth stages. Is there an easy way to control the grow lights to achieve the best spectrum? Adjustable spectral light intensity + smart plant lights that automatically execute lighting strategies are the best choice. more info about the best LED grow light 2022 : https://www.ultraplantled.com/

Why is it always difficult and time-consuming to make decisions when purchasing grow lights? Because many people will tell us that we need to know many factors before buying: light intensity, consistency, spectrum, professional terms such as PPF, PPE, PPFD, Wattage, etc. With so many nouns and concepts, it is easy to confuse people. In fact, to make a wise choice, you do not need to fully understand these terms. The following will simplify everything for you. You only need to do simple calculations according to the formula to get the best and most suitable product. Just focus on PPFD, don't care about PPE and PPF Many people will say that PPE means the efficiency of the lamp and PPF means the amount of light in the fixture, which is true but has no practical meaning. This is because light is what the plant can actually receive, and PPFD is the only indicator of how much light the plant canopy can receive. The PPFD value is not completely controlled by the PPF. So regarding the amount of light, we only need to focus on the PPFD value. On the other hand, regarding energy efficiency: the actual electricity consumption of a light fixture is only related to its wattage. So when it comes to efficiency, we should pay more attention to PPFD/W, which represents the real efficiency of lamps and lanterns, and indicates the cost of long-term use. The smaller the value, the less electricity will be consumed during long-term use. Is Full Spectrum the Best? Regarding spectrum, why do people say they need full spectrum? Because each plant and the optimal light formula required for each growth stage is different, the full spectrum is like a buffet, allowing plants to choose. But this buffet style, because it is too free, can not get the best harvest. The best way to do this is to manually select the most suitable spectrum for the plant, so that control can enhance the certainty of the desired outcome. At the same time, many scientific experiments have shown that controlling the spectrum can control the characteristics of plants, whether it is morphology or the flavor of the harvest. Therefore, it is best to choose a tunable full spectrum. By the way, full spectrum means that the simulated sunlight contains all the mixed light of different wavelengths. It is impossible for actual artificial lighting to restore sunlight 100%, but plants actually only need the following 5 kinds of light: red, far red, UVA, deep red, blue green So about the spectrum, choose a tunable broadband spectrum containing the above-mentioned light wavelengths, why is it broadband light? Because of the color of the light, the color of the mixed light containing these lights is usually white, not red, blue or purple, which is conducive to observing plants during the planting process and detecting pests and diseases in time. According to the above concepts, it can be summarized into such a set of selection methods: 1. Know the minimum and maximum PPFD requirements of the plant, and choose a plant light that meets the interval 2. Judging the benefit through the cost of PPFD/W 3. Optimal screening through adjustable full spectrum. Feton smart grow light, a collection of full-spectrum integrated lamp beads and a full-intelligent control system. Not only can the spectral intensity control customization be realized, but also the lighting strategy can be automatically executed. Use advanced technology to bring convenience to growers and increase yields. More info about led growl light: https://www.ultraplantled.com/full-spectrum-grow-light/

For ordinary household vegetables or other plant cultivation, it is always difficult to obtain a stable harvest due to seasonal or weather restrictions, or it takes a long time to wait. But why do some people in the same climate get healthy vegetables or plants quickly? The secret is the grow lights which allows enough lighting every moment. That keeps plant growing in high efficiency. Whether or not grow lights are used during planting has a great impact on the growth cycle time. For some plants, it can even shorten the growth time by 1/2. Even in ordinary home planting can have the same result. Because the planting experiments we are going to share were conducted under ordinary home indoor conditions. Different wavelengths of light have different effects on plants, and each plant and each growth stage requires different light. Therefore, the ideal artificial light source should be able to do adjustable. In the planting experiment, for convenience, we just made a full-spectrum plant light. The vegetable grown is arugula. Two plates of arugula were placed next to each other in the same room, with the same medium and seeds. In the first few days, there was no difference. The amazing thing was that after more than ten days, it was obvious that the arugula that had been taken care of by the grow light had grown up and could be harvested, while the arugula under natural light is still small. It usually takes 30-40 days for Arugula to grow to the harvestable stage under the same natural light in the same environment. Now it only takes about 1/2 of the time, just because the light source is increased, and there is no other change. Ever wonder why I can't always grow good plants or planting is too hard and boring for me? This is actually not a problem of the growers, but a problem of the weather. Although there is temperature in the room, there may not be enough sunlight due to insufficient lighting indoor or seasonal reasons. So a grow light can solve the troubles, easily grow healthy plants, and enjoy the joy of a quick harvest. Feton grow light is specially made for home indoor grow, the small wattage is equipped with APP to intelligently control the spectrum, customize the switch or switch spectrum, working time, etc. Allows you to achieve a variety of planting, zoning control. If you want to grow a larger area, just add one more model, Feton grow light supports group controlled for multi models. More info: https://www.ultraplantled.com/150w-led-grow-light/61764777.html

Why we always hear the comparison of LED grow light VS HPS? Because more and more market data shows that LED grow light is the future of grow light. But HPS once represented an era of cannabis grow lights, and many still use HPS to grow cannabis today. So people is hesitate hen facing the choose of LED and HPS. On the question of comparison, almost all answers are from the perspective of energy cost and LED spectrum customization. But as a grower, it is obviously more concerned about whether the harvest is different, whether it is more or of higher quality. Today we are going to share a growing experiment that directly tells us how cannabis grows differently under different lights. The experimenter selected several common LED grow lights on the market and an HPS light as the experimental objects. In the first step, the researchers selected the products with the most uniform light distribution from the LED grow lights, because the LED grow lights are composed of many lamp beads distributed on the panel. Its light distribution will depend on the distribution of its lamp beads. The light consistency is an important factor in determining whether a high-quality end product can be obtained. After selecting the lamps, the researchers used LED grow light and HPS light to plant three times respectively, and then analyzed the difference in harvest quality. The results are shown as the following picture: The THC-A content of each LED grow light harvest is always higher than that of the HPS light harvest, and is as high as 5.39%. The researchers show that this is mainly due to the fact that the spectrum of LED grow lights can be customized and optimized compared to HPS, and the use of LED grow lights can make the growing environment more easy to be controlled. So actually not all LED grow light can increase the harvested THC, the focus is on its optimized spectrum, but we have shared before, the same cannabis, different varieties, to obtain high THC, its best spectral light intensity Wait is different. But the grow lights on the market basically have a fixed spectrum, so the grower should choose carefully and it's not an easy work. However, the Feton grow light give an solution to make everything simple: Feton grow light : With its spectrum and intensity dimming function, it can adapt to a variety of lighting strategies. Growers can experiment to find the best lighting strategy for their species. Let the plant grow the highest quality and highest number of crops. More importantly, its LED chip is with high uniform, instead of using various colors of LED chip to make full spectrum, it use the patented ALL in one LED chip -- each single LED chip is with 100% same spectrum and same intensity.

Cannabis is a crop with high economic value. With the liberalization of policies, more and more regions allow people to grow and use cannabis at home. Growing cannabis at home is becoming more and more popular, just know these basics to get you started Before understanding the specific cultivation techniques, let's understand the cannabis plant first There are 4 main growth stages for cannabis: -Germination (3-10 days) -Seedling (2-3 weeks) -Vegetative (3-8 weeks) -Flowering (8-11 weeks) Each variety of cannabis has a little bit of differentiated needs at different stages of its life. This can be learned from suppliers when buying seeds, but in general one of the keys is that when promote flowering, shorter light times are often required. Lighting time usually become 12 hours or less. The later formed Cola is rich in THC and CBD, and when the hairs on top of the Cola turn brown and curl inward, it is time to harvest. Then by drying in a dark, airy space, pruning can be done once the flowers are dry, leaving useful buds. Here are the 6 most important points for growing marijuana at home: 1. Genetics determine the lower limit of cannabis' performance The genes of cannabis seedlings basically determine how the plant grows and its final yield or content of useful substances. The later tools and planting method optimizations are only 100% of his talent or only slightly improved. So the most important step is to buy cannabis seeds or seedlings with good quality genes 2. The correct growing medium Cannabis can be grown in soil, coir or hydroponically. Each of these methods has advantages and disadvantages, and it is important to find the best growing medium before planting! If you're a beginner looking to grow cannabis at home, we recommend starting with a quality potting mix (peat-based). Ensure optimal airflow from the start by using fine mesh pots/containers filled with perlite, vermiculite or clay pebbles. This will ensure good drainage while the plant is growing, while allowing plenty of air to pass through after the plant blooms without interfering with water retention too much. Cannabis plants love water but hate soggy roots! Unless, of course, you're running a hydroponic setup. The pH of the medium plays an important role in the health of the plant. Cannabis plants prefer a pH range between acidic and neutral. A pH of about 6 is ideal. Soil made for hemp usually contains enough nutrients for 3-4 weeks of growth. 3. How and when to water your cannabis Adequate water needs to be ensured during the vegetative and flowering stages of the plant. Allow sufficient time between watering to ensure that the roots of the plant have enough time to drain excess water. You can feel it by sticking your fingers a few centimeters into the top of the soil. If it feels like a supermarket, then it should be about 1 hour before watering. 4. Plant training Plant training mainly refers to the adjustment of the plant shape by pruning, correction, etc. during the growth of the plant, so that the plant can form the shape that obtains the maximum yield. This is a relatively difficult method, and it is not easy for beginners to learn, but beginners should try various methods freely. Here is a brief introduction to a common method: Low Stress Training (LST) It requires bending, tying, and proper pruning of branches during the vegetative growth phase of cannabis, encouraging the plant to grow flatter and thicker to make the most of light and maximize yield! This can be done by using wire or soft ties. 5. The right nutrients Cannabis plants need the right nutrients during the vegetative growth stage to produce healthy yields. Overfeeding cannabis plants can cause nutrients to burn and, if left untreated, can damage or even kill your plants! So it's important to make sure you're using a pH calculator for your water when mixing your nutrient solution; keeping it in the 0.50pH range on either side of neutral is ideal for cannabis. The main nutrients are nitrogen (N), phosphorus (P), potassium (K); vegetative stage: NKP generally maintains 3:1:2; flowering stage requires more phosphorus and potassium, the ratio is 0:3:3 6. Correct lighting Cannabis is a light-loving plant. There are many things to pay attention to about light, but it must be known that different varieties and different growth stages have different optimal spectrum, light intensity and light time. Fortunately, home cultivation does not need to be as refined as commercial cultivation. However, it is necessary to adjust the general light intensity and light time and spectrum in time. For example, the light time in the flowering stage is shorter than that in the growth and vegetative stage. A good plant light control can also help reduce cannabis pest and disease risks. The trouble is that good lighting often needs to be adjusted regularly by growers, such as switching lights on and off according to the light and dark period every day, and adjusting the light time, spectrum, light time and light intensity at each growth stage. Fortunately, smart grow lights are already here. For example, Feton's smart lights are the most suitable smart lights for beginners. The small wattage modular design reduces the trial cost for beginners. Even 150W has intelligent functions, and the planting scale can be expanded at any time by splicing more models. Its intelligent control function can automatically execute the lighting plan according to the plan every day as long as it is set once, without manual repeated operation. It frees your mind and time.

How many grow lights can be under one grow light is a frequently asked question. Because this problem is an unavoidable prerequisite for setting up an indoor grow room or tent. Next, this article will reveal how to choose plant lights according to the planting area, or how many plants to match according to the plant lights. There is no one-size-fits-all answer to this question, as he will set it based on several different conditions 1. Need to know the plants which is going to be planted This step is mainly to understand the required light intensity of the plant, which is generally expressed by a unit DLI (daily light integral). For details, please refer to our article.(https://fetonlight.bossgoo.com/news/how-to-decide-the-lighting-distance-of-your-led-grow-light-78726.html) In short, 24 hours a day, plants need to have light time and dark period in different growth stages. Because the light time of a day is limited, there will be a requirement for the instantaneous light intensity of the lamp, and this requirement is PPFD. So we first need to know the DLI and optimal photoperiod required by the plant and its various growth stages. 2. Determine canopy coverage The canopy generally refers to the topmost part of the plant that receives light most preferentially. Why canopy coverage does not necessarily equal the canopy area of a grow tent. Because plants generally cannot occupy the entire area of the planting space during the planting process, which means that some space is wasted. There are no plants in this area, so there is no need to consider that the entire area needs to be illuminated. 3. Understand Grow Lights This step is mainly to understand the intensity change of the grow light. You may have heard of many units about this, including PAR, PPFD, PPE, etc., but in fact, about the intensity, you only need to guide the PPFD. Usually, this PPFD is in different The hanging heights of the LEDs are not the same, there is a simple rule: the higher the hanging height, the larger the light coverage area, but the light intensity, the less the PPFD value. Generally, different growth stages of plants require different light intensity, which can be adjusted by adjusting the hanging height. At this point, if you do not have professional measuring equipment, then ask the lamp seller to provide a PPFD chart. By knowing the DLI required by the plant and its optimal photoperiod, you will know the minimum PPFD required by the plant, combined with the expected coverage area of the plant canopy, and whether the area covered by the control plant light and its corresponding PPFD value are in line. In this way, you can know whether the plant light you want to buy meets your needs, or decide how many plants are suitable for growing under the plant light. Because most of the PPFD of the plant lights on the market are fixed, when you want to change plants or increase the planting area, you will have to consider changing a plant light to adapt to it, but there are not many lamps, so be careful to confirm before setting up Well the above things. Once set up there is very little room to change. If Feton grow lights are used, the situation will be different. Because Feton grow light adopts a modular design of small wattage, it can be planted in a larger area by splicing. At the same time, its intelligent control system allows growers to adjust the light intensity and spectrum at any time. In this way, the grower has a very large adjustment space during the planting process, both in terms of the planting area and the plants planted. It is a beginner friendly but professional grow light.

Many LED lighting suppliers will say that full spectrum LED grow lights are the best choice for growing plants because they mimic natural light from the sun. Because: "Plants have grown in the sun for millions of years. Why should we change the best things nature knows?" This is a good idea, but in fact, the full spectrum that most manufacturers say is not the sunlight spectrum, and the real sunlight spectrum does not exist on the market, or plants do not need it. First of all, what is contained in sunlight is very complex, including X-rays, radio waves, etc., so far scientists have not figured out, but regardless of which ones are not considered, sunlight also contains a very broad spectrum such as UV and far red. As shown below According to most of the current research, plants do not actually need such a wide spectrum, of which the PAR range is the most famous, PAR refers to the spectrum in the range of 400-700nm. The prevailing view is that this range of the spectrum is the one that allows plants to photosynthesize most efficiently. The traditional view also believes that in this range, red light and blue light are the most efficient. Therefore, most of the early LED grow lights are composed of red LEDs and blue LEDs. The color of this grow light is purple. Later, it was found that green light actually has a synergistic contribution to the photosynthesis of plants, and it was felt that during the planting process of purple light, it was difficult for people to observe the appearance of plants, so as to detect diseases and other problems in time. Therefore, LED grow lights consisting of white light beads, red light beads and blue light beads arrays appeared, also known as full-spectrum lights. One of the advantages of LED grow lights compared to other traditional grow lights, such as HPS, is that the spectrum can be customized. Because of this property, scientists have found that the right amount of far-red and UV light plays an important role in plant health, morphology, and harvest quality and quantity. We have shared these two aspects before, details (https://www.ultraplantled.com/news/led-grow-light-can-affects-taste-of-vegetable-or-cannabis-79490.html) or (https://www.ultraplantled.com/news/how-plants-affected-by-far-red-lighting-730nm-77574.html) A true full-spectrum grow light is not limited to PAR(400nm-700nm), nor is it only white light + red light + blue light, but should include important light segments such as UVA and far-red. Therefore, the most advanced full-spectrum plant lights on the market will use lamp beads containing these bands. But unfortunately, due to cost considerations, these devices are often a lot of white light + a small amount of UV or far-red or red light, these special lamp beads, resulting in a spectrum with only a lot of white light, very weak far-red or UVA, especially due to the lamp If the number of beads is small, the plants under the lamp will be affected by the distribution of the lamp beads and receive a very different spectrum, which will affect the uniformity of plant growth. Feton grow lights use patented lamp bead technology to break through the problem. The spectrum contains all the light segments needed by plants and has enhanced peaks. Instead of using multi-color narrow-band lamp beads to spell the spectrum, each lamp bead has the same full spectrum. There is no worry about the distribution of different color lamp beads. Every plant under the lamp can receive the same full spectrum. At the same time, it has adjustable functions to match a variety of plants and growth stages.

Light burn is one of the growing problems that many growers often face, especially for beginners. Light stress will happen when plants is exposed to too much light. Light stress refers to the state when plants receive excessive light, which is harmful. If the plant is under light stress for a long time, it will cause light burn. Therefore, light burn is generally caused by the incorrectly use of artificial light sources, and the harm will lead to yield reduction. How do you find out that your plants have light burn? Many people will judge by the color of the leaves, for example, the leaves change from green to yellow or brown; but in fact, only yellow leaves can not be sure the light burn happened, because nutrient burns(nute burn) also have similar phenomena. Nute Burn is due to the excess of nutrients in fertilizers, which block water, so the lack of water in plants causes the leaves to change color. Therefore, when you see that the leaf color has a color change, you can also rule out whether it is nute burn by checking whether the root also has a color change. Because nute burn usually starts from the root of the plant. Other typical feature when light burn happen: 1. Bleached buds If the plant has buds, when you see the buds are bleached, you'll see them clearly white. 2. Green veins The leaves will start to turn yellow at LB, but the color of the veins will not change, which means the leaves will not turn completely yellow 3. Yellow leaves that do not fall Normally yellow leaves fall naturally, but with LB, this does not happen. However, if your plant's leaves change color and fall off at inappropriate times, it may be due to other problems such as nutritional deficiencies How to cure light burn ? Since light burn is because of too strong light intensity, so the only way is to adjust the light intensity. The general method is to adjust the distance between lamps and plants. This is for old school plant lamps without light intensity control. It's a troublesome method. Why? Because the light intensity and DLI that can be endured by each growth stage of the plant are actually different, it needs to be adjusted regularly according to the growth of the plant, and sometimes it faces the difficulty of insufficient space. Therefore, it is more suitable to be equipped with LED grow lights with control function. We recommend a grow light equipped with intelligent control like our grow light Ultra Plant, which can not only control the light intensity but also the spectrum, and can also set the working time. It is more punctual and automatic than gardeners. What's more, our grow light with smart functions has a wide selection from 150W to 1000W.

Cannabis cultivation is becoming less regulated. Small-scale planting by individual households has been opened up in many areas. Compared with large-scale commercial planting, personal planting has very different demands on grow lights. why? The main reason is that personal cultivation is a part-time job, which is destined to be limited in time and energy. The more pursuit is to enjoy the convenience of marijuana, or to enjoy the freshness of marijuana cultivation. Therefore, for planting, it pursues a good harvest under a limited budget, and requires a low level of trial cost. Then reflected in the product, Feton Ultra Light™ new generation of small wattage smart plant light is the most suitable for amateur / household indoor marijuana cannabis grower. Why ? 1. Save budget for lighting timer. Free your hands and mind allow cultivation become easy. Feton grow light™ can be used with APP and has a simple operation program setting function. Plants need different light intensities at different growth stages, and at different stages, they need to be switched on and off every day, because plants also need "evening" to rest. This requires growers to operate the grow lights regularly every day, and if there is a mistake in certain critical stage such as flowering, it will also incur heavy losses. But with our auto-run feature, just set it up once, and the grow light will automatically work for you, become your gardener, and take care of your plants. 2. Greatly lowers the entry threshold for planting and helps growers get started easily Most of the lamps equipped with intelligent functions on the market are large-wattage lamps for commercial use, and the operating software is complicated and expensive. Obviously it's a huge challenge for amateur growers. The Feton Ultra Light™ independent low-wattage modular setting allows each 150/200W unit to be equipped with a simple and practical control APP. It brings lower choices for amateur growers, and if you want a larger wattage later, you can use the form of multi-unit splicing. 3. Infinite spectrum adjustment, keep planting and harvesting always fresh. Every plant and even every different variety of the same plant has different needs for the best spectrum. At the same time, the spectrum can affect the shape or taste and flavor of the plant during the planting process. Feton Ultra Light™ features spectral adjustment to create an infinite kinds of spectrum. Growers can adjust the lighting strategy at any time, or change the plant species. Why is it difficult for home/amateur growers to grow high-quality products? An important reason is that there are no grow lights on the market specifically designed for them. Feton Ultra Light™ fills this gap. More product information: https://www.ultraplantled.com/150w-led-grow-light/

Although the effects of UV cultivation have been studied for many years, there are still many misconceptions about UV, including the belief that all UV is bad for plants, or that only UVB is valuable. Next, we will share with you some research results on the benefits of UV-A for planting. First let's take a look at what is UV? The general term for light in the wavelength range of 10nm-400nm, which is subdivided into UVA/UVB/UVC. They correspond to different wavelength ranges respectively. UVA: 320nm-400nm / UVB: 275nm-320nm / UVC: 200nm-280nm. The shorter the wavelength, the stronger the damage ability to living things, but the weaker the transmission ability. Due to the presence of the atmosphere, almost no UVC reaches the Earth's surface. At sea level near the equator, 6% of solar radiation is ultraviolet, of which UVA is 5.7% and UVB is 0.3%. Depending on latitude, altitude and time of year, plants receive 10 to 100 times more UV-A than UV-B. Therefore, it can be said that light containing UVA is in line with the natural living environment of plants. Reasons to use UVA for indoor cultivation: 1. UV-A increases production Often misleading UV studies are not done on whole leaves or whole plants, but just some algae or chloroplasts. In fact, plants themselves have good natural adaptability to UVA, and different species show similar responses but different response mechanisms. The following series of studies have collectively demonstrated the above opinion. 2. Increase the nutritional value of harvest We all know that human exposure to moderate amounts of UV rays has benefits, such as boosting the body's synthesis of vitamin D. A similar reaction occurs in plants. Plants respond to low-dose UV light by producing antioxidant compounds such as flavonoids and phenolic compounds, which often give fruits and vegetables their bright blue or purple hues. And many of these compounds are antioxidants, which are beneficial to the human body. Flavonoids are strongly associated with longevity, weight management, heart health and reduced cancer incidence and avoidance of neurodegenerative diseases. Other phenolic compounds are also of great interest for the prevention and treatment of cancer. 3. UVA changes the growth state of plants and allow it to have better growth. Plants will judge their position according to the change of light quality, so as to adopt different growth postures. A typical example is the shading effect. When the spectrum loses ultraviolet, blue and red light and contains a high proportion of green and infrared light, the plant will think that it is shaded, then it will grow leggy and cannot bring a good harvest. The opposite plant will think that it is bathed in sunlight, resulting in better growth. Below are some of the findings. 4. UVA can effectively control plant diseases. UVA light will increase the thickness of the leaf surface, thereby increasing the resistance to fungal infection. At the same time, there is a near-UVA light with a wavelength of 405nm that has been proved to be harmless to organisms such as humans or plants, but it can kill bacterial diseases. . For details, please refer to our previous article introduction (https://www.ultraplantled.com/news/why-your-cannabis-grow-light-needs-uv-77491.html) All in all, an effective grow light should contain UVA. Most 3500K/6000K grow lights on the market do not have light in this band at all. Ultra Plant™, a brand of grow lights of Feton, is serving the plants and growers with the most comprehensive spectrum.

Microgreens refer to the seedlings of vegetables or flowers and are considered one of the five most valuable cash crops in the world. Its growth cycle is fast, and it can be cultivated without soil. Therefore, it is very suitable for large-scale indoor planting in families or cities to achieve self-supply of food in cities. This plant is sensitive to the light environment, in fact, low light, plant growth and nutrient content will be inhibited, but excessive light intensity will photosystem, electron transport and ATP synthase complex and Calvin-Benson Circulating enzymes have adverse effects, so plant needs need to be clarified. In addition to this, lighting quality is also a factor. Therefore, successful planting requires an understanding of the light preferences of these plants. The following experiment brings us great inspiration. The scientists selected China Rose Radish (Raphanus sativus L.), Green Mizuna (Brassica rapa L. CV Nipposinica), Chicory (Cichorium intybus L.), and Alfalfa (Medicago) sativa L.), French Marigold (Tagetes tenuifolia CAV.) and Celosia (Celosia plumosa argentea L.), these typical microgreens were used for experiments. Each plant was exposed to two different light spectra and three light intensities. The two different spectrums are red-blue and red-blue-green. The three light intensities were PPFD 110/220 and 340. The results showed that the light quality and light intensity combinations required for optimal performance of different species were different. As shown in the picture below: The best performance of China Rose Radish is at PPFD 110 + red blue light; while Green Mizuna is PPFD 340 + red blue green light. As food crops, people usually like to diversify their cultivation to meet the needs of diverse tastes. But most fixed-spectrum grow lights on the market mean that we may need to buy a lot of different kinds of lights. Buying only one type of lamp means you won't get the best harvest when trying to switch varieties. To this end, Feton Ultra Plant™ has launched a new light intensity spectrum adjustable function, a lamp with unlimited spectral light intensity combination. What is even more powerful is that it adopts a single model 150W modular design. When you need a larger planting area, you can quickly splicing multiple models, flexibly upgrade the light map, and take combined control.

As we all known, cannabis is a light-loving plant that requires high-intensity irradiation. But actually the light intensity requirements of different growth stages is different, the flowering stage is the one that needs light the most, so the growth stage with the highest light intensity is generally the standard when choosing a plant lamp. After all, low intensity can be adjusted in a variety of ways if with hight intensity. So when choosing lights, is the brighter the better? Firstly, it needs to know about the relationship between light intensity and harvest. Take a look at the following schematic diagram of the experimental results. Scientists grow the same variety of cannabis at the flowering stage by using different light intensities. Light intensity increased from PPFD 350 to 1400. The total yield and harvest index also increased linearly. However, it is worth reminding that in this study, the scientists also controlled the input of various elements of the planting environment to meet the nutritional needs of plants under different light intensities, so this study can be said to be free of cost . As a grower, what is needed is the input-output ratio, more light means the input of lamps, more electricity bills, more nutrients, more carbon dioxide, etc. If environmental factors cannot cooperate with light, it will not only waste electricity bills, but also damage plants. Feton Ultra Plant™ grow light, innovatively adopts small wattage modular design, each 150W light is an independent module, can get a large wattage grow light through simple splicing, and is equipped with intelligent control system. Allows growers to control or upgrade light intensity at low cost, and adjust light strategies at any time. More product information:https://www.ultraplantled.com/150w-led-grow-light/

More and more people are trying to grow their own cannabis. However, marijuana is a light-loving plant, and many places don't have enough light conditions. At the same time, regulations often stipulate that growers must "hide" the cultivation site of marijuana. Therefore, artificial light is indispensable, and LEDs are becoming more and more mainstream because of their advantages of perfect spectrum, and low temperature. Here are 3 points you have to know about using LED grow lights to grow cannabis, you would understand the advantages of LED grow light better as well. 1/ When your plants are in the seedling stage after germination, you need to turn on your grow lights. Note that the light in the seedling stage cannot be too strong or too weak, so you need to adjust the intensity of growth. There are generally two ways: one is to adjust the distance between the light and the plant, and the other is through the control system on the light (if your plant light has one). Another important point is that the daily light integral (DLI), DLI is related to the daily light time/photoperiod and the light intensity of the lamps. For details, please refer to our article (https://www.ultraplantled.com/news/how-to-decide-the-lighting-distance-of-your-led-grow-light-78726.html); generally, 18 hours per day for Lighting and 6 hours of darkness for this stage. 2/ After the seedling stage, the plants enter the vegetation stage. At this time, pay attention to increasing the DLI, and the photoperiod is generally set to 18 hours of light and 6 hours of darkness. Another important point is that when you increase the DLI, you should pay attention to the coordination of the growth environment, such as the increase of carbon dioxide concentration and sufficient nutrients to ensure that the plants can fully utilize the power of light. 3/ When the plant grows to a certain height, you can induce flowering by changing the photoperiod, which is imitating the seasonal changes in nature. The flowering period is generally set with a photoperiod of 12 hours/12 hours. The point is to maintain absolute darkness during the dark period. Once the dark period is interrupted by light, one cannot expect satisfactory results. In fact, experienced growers deliberately switch to lights with a greater proportion of red light during flowering to boost yields. To sum up, to grow good cannabis flowers, growers need to switch the lights on and off every day to control the photoperiod, and adjust the light intensity at different stages. Experienced growers also use lamps with different spectrums depending on the growth stage. According to research, even the optimal light strategies for different cannabis varieties are different. As a result, it is a complex and repetitive process that requires a considerable investment of time and effort from the grower. But there is a way to reduce the operation cost of the grower and the risk of making mistakes in planting. It's to set it up and hand it over to the robot to execute it perfectly. Smart lights like Ultra Plant™, have the ability to adjust and automate spectrum, intensity and runtime change. Makes planting easier and more harvestable at the same time.

In an article we introduced how LEDs affect the taste of plants(https://www.ultraplantled.com/news/led-grow-light-can-affects-taste-of-vegetable-or-cannabis-79490.html). In addition to taste, harvest appearance and nutrient content are another important dimension in commercial cultivation. Recently, an organization has given us a big hint by using different spectra and different intensities to grow red lettuce. Control the grow lights and you will be pleasantly surprised. The group's experiment went like this: Using two different spectrum lights, each with three different intensities, was used to grow red lettuce. The only difference between the two lamps is that one contains enhanced UVA and blue light. It turns out that: 1. The stronger the light intensity, the higher the anthocyanin of the lettuce and the redder the color. 2. Contains enhanced UVA and blue light spectrum also shows enhanced effect on anthocyanin and red In fact, as early as 2009, an experimental paper¹ stated that UVA and blue light can increase anthocyanins, while far-red and green light have opposite effects. The difference is that the 2009 experiment was done through with separate supplemental lights, this time by combining useful and other wavelength lights into a single grow light. These experiments all proved the influence of LED intensity and spectrum control on vegetables. Most of the plant lights on the market currently have non-adjustable spectrum and are not targeted to certain plant. Therefore, users can only obtain the effect by purchasing new lights separately, which will increase the additional costs, So a better approach is to directly own a product like Ultra Plant™ with 100% adjustable spectral intensity, giving the grower maximum freedom to develop the best lighting strategy .

In terms of plant disease, the traditional means are various artificial chemical fungicides. However, today people have higher and higher requirements for food safety, and the restrictions on the use of various crops are becoming more and more strict. For example, the American safety requirement of cannabis which we have introduced before (https://www.ultraplantled.com/news/why-your-cannabis-grow-light-needs-uv-77491.html). In fact, with the popularity of LED plant lights, controllable lighting conditions have been proven to be an important means of plant disease treatment. A study by Bahian University in Israel proves this. The university's research is against downy mildew, which is commonly found in basil. The fungus, which reproduces by spores at night, causes basil to turn yellow and purple and lose its aroma. In fact, this disease is not unique to basil, it is also common in important crops such as cucumbers and corn. The researchers exposed infected basil leaves to 5 or 10 micromoles of blue, green, red or incandescent light at night. They were incubated for 20 hours in a growth chamber under humid conditions at 20°C. The results showed that red light (peak at 625 nm) inhibited sporulation by 99.7%, regardless of whether the leaf surface was exposed to light. It is worth noting that the team mentioned that other teams have previously studied the response of the same disease to light in different plants such as cucumber and tobacco leaves, but the conclusion is that the effect of blue light is better. That indicates 2 points: 1/ Effective inhibition and treatment of plant diseases not only requires the wavelength of light, but also controls the time of light according to the pathogenesis 2/ The same disease but different types of bacteria may require different specific light. Therefore, in terms of choosing grow light, the one with spectrum modulation + lighting time management can give growers higher value. Most of the plant lights on the market are traditional plant lights with a fixed spectrum. Ultra Plant™, as a new generation of plant lights, breaks the routine, with full spectrum + 100% adjustable + intelligent setting control to maximize the effect and benefits of plant lights.

Whether to use HPS or LED for commercial cannabis cultivation has always been a tangled issue. Many people know that LED lights are higher than HPS, although more durable, but the initial investment cost is higher. What many people don't know is that LEDs are creating greater profit margins for growers in terms of planting environmental control. This is why in just 4 years, the growers who use LED grow lights at all stages have increased from 21% to more than 60%. The pursuit of cannabis cultivation is high yield, and high yield must rely on a stable and controllable cultivation environment. LED grow lights have the following advantages in assisting environmental control: 1 Saving HAVC device cost and better for Vapor Pressure Deficit Management: The heat dissipation of LED work is much smaller than that of HPS. On the one hand, it can save the cost of HAVC equipment and the cost of power consumption. On the other hand, the temperature fluctuates greatly when the HPS is turned on and off, and another key link in planting is VPDM. When the temperature fluctuates greatly, because HAVC is too late to adjust, it is likely to cause too high or too low VPD, hindering the growth of plants, but using LED is more conducive to faster control of temperature stability and maintain a stable VPD. 2 Reduce the use of chemicals: We know that light with specific wavelength can kill viruses or bacteria but safe to human and plan, for example the 405nm. Because LED lights can be customized to emit light of specific wavelengths, they can have the advantage of sterilization, create a healthy environment for plant growth, reduce the use of chemicals, and bring to stabilize organic production. Refer to this article to learn how grow lights can protect plant health: https://www.ultraplantled.com/news/why-your-cannabis-grow-light-needs-uv-77491.html 3 Precise lighting strategy control: At the early time, we shared that different kinds of plants / the different cultivars of the same plant, and different growth stages of plants have various needs for light spectrum and light intensity (https://www.ultraplantled.com/news/different-plant-needs-different-grow-light-cannabis-cultivation-research-78090.html). The spectrum of HPS lamps is fixed and doesn't give the most suitable spectrum. But spectrum of LED grow lights can be customize. However, most of time the spectrum only can customized in the factory, it can't fit for each cultivator. A a better choice is an intelligent LED grow lights, such as our Ultra Plant™, have dual functions of spectrum regulation + lighting plan automation. Each growers can adjust according to the changes in actual situation any time. More information of Ultra Plant™, welcome to visit: https://www.ultraplantled.com/600w-led-grow-light/61922761.html

Commercial cannabis growing always pursue a best cultivation environment. Since different growth stages of plants have different spectrum and light intensity preferences, when using traditional LED lamps, we often take the following two ways: 1. In different growth stages of plants, to replace or adjust growth light fixtures. For example, add a separate 730nm far-red light when approaching the flowering stage of the plant. 2. Set up different planting rooms and install LED plant lights of different spectra. For example, a room is used as a seeding room, a room is used as a vegetative room, and a room is used as a flower room. Then at different growth stages of the plants, move them out of one room and into another.

The traditional view is that the taste of plants is completely decided by the genes of the species, and there is no way to change them through cultivation techniques or ecological conditions. Light also only affects plant morphology or yield. However, based on experiments conducted by an organization, this view may be wrong. This organization grows the sweet basil with two groups, each using different light recipe. Group A: Group B: Aside from the spectrum, the rest of the growing conditions were exactly the same. After the same growing time, picking and scoring according to different flavor dimensions, the result shows obvious differences. It turns out that by controlling the spectrum, growers can obtain their own unique product. Unfortunately, most plant lights on the market have their spectrum determined at the factory, not to mention that the optimal spectrum required by different plant species is different. Even within the same plant species, different spectra can yield different products. This means that LED plant lights with a fixed spectrum are not conducive to growers to create products with differentiated competitiveness. The spectrally adjustable function of Ultra Plant™ exists precisely to help growers cultivate differentiated products.

When it comes to the installation distance of plant lights, many people will blurt out 30 cm or 45 cm. In fact, this statement is not rigorous. The amount of care required by each plant is different, and this data is generally measured by DLI (Daily Light Integral). It is converted to the familiar PPFD as follows: DLI = mol/㎡/day PPFD = umol/㎡/second DLI = PPFD x 3600s x lighting hours / 1000000 PPFD = DLI x 1000000/ lighting hours / 3600s Therefore, to determine the installation distance of the plant light, we first need to know the DLI and the necessary photoperiod required for each growth stage of the plant. (The so-called photoperiod refers to the ratio of plant light time to dark time. For details, please see this article: https://www.ultraplantled.com/news/why-you-need-a-smart-control-grow-light- 77013.html) Assuming that the DLI required by a plant is 40 mol/㎡/day, and the daily light time must reach 12 hours, then its PPFD must reach: 925.92 umol/㎡/second = 40*1000000/12/3600 This means that the grow light must be installed in a place where 925.92PPFD can be obtained. If your plant light PPFD is not high enough, the easiest way is to shorten the distance between the light and the plant to get a higher PPFD. But one thing to note is that most of the current LED grow lights have a structure similar to the following: This also means that the closer the LED grow light is to the plant, the more focused the light (especially the special spectrum such as deep red), and as a result, only a small part of the plant can absorb the special spectrum, resulting in extreme spectral imbalance. Therefore, it is impossible to obtain infinite PPFD by continuously shortening the installation distance of the grow light. Ultra Plant's ALL-IN-ONE Technology solves this problem, each LED chip can emit a full spectrum including White Light, Deep Red, Far Red, UV, ensuring that no matter how the distance is adjusted, every The same spectrum can be obtained for all parts. Basing on that, we can achieve a higher Maximum PPFD than most LED grow lights. More info of product, welcome to visit:https://www.ultraplantled.com/600w-led-grow-light/61922149.html
