Plant lamps are used for indoor horticulture, indoor plant tents
,plant propagation and food production, including indoor hydrophytes and aquatic plants. Although most plant lamps are used in industry, they can also be used in the home.
The plant growth lamp is an artificial light source, usually an electric light source. It aims to stimulate plant growth by emitting electromagnetic spectrum suitable for photosynthesis. Plant lamps are used in applications where there is no natural light or where supplementary lighting is required. For example, in winter, when the possible daylight time may not be enough for the plant to grow, the lamp is used to extend the time for the plant to receive light. If plants don't get enough light, they will grow in vain.
The growing lights either try to provide a spectrum similar to that of the sun, or a spectrum more suitable for the needs of the cultivated plants. Simulate the different colors, temperature and spectral outdoors from the growth lamp, and change the lumen output (intensity) of the lamp. According to the type of plant cultivated, the cultivation stage (such as germination / nutrition stage or flowering / fruiting stage) and the photoperiod required by the plant, the specific range of spectrum, luminous efficiency and color temperature are all desirable specific plants and time periods.
What effect does light have on plants?
Effect of light on plants: light can promote photosynthesis of plants. The stronger the blue-green light and red orange light, the more can promote the photosynthesis of plants. Generally, white light can be used to irradiate, but led light should not be used as far as possible. The radiation of this kind of light is very low, and it does not promote photosynthesis of plants. Photosynthesis, namely light energy synthesis, refers to the biochemical process that contains chloroplast green plants, animals and some bacteria, under the irradiation of visible light, through light reaction and carbon reaction (formerly known as dark reaction), using photosynthetic pigments to convert carbon dioxide (or hydrogen sulfide) and water into organic matter, and release oxygen (or hydrogen). At the same time, there is an energy conversion process that converts light energy into chemical energy in organic matter. Photosynthesis is the sum of a series of complex metabolic reactions. It is the basis for the survival of the biological world and an important medium of the earth's carbon oxygen balance.
What color is the plant growth lamp?
Photosynthesis is carried out by plants through chlorophyll. There are two main spectral ranges that chlorophyll can directly absorb. One is the red part with the wavelength of 640 ~ 660nm, the other is the blue and purple part with the wavelength of 430 ~ 450nm. In addition, lutein and carotene in plants can also absorb light energy and then transfer it to chlorophyll for photosynthesis. The absorption spectra of lutein and carotene are different The range is about 400 ~ 500nm, which is slightly wider than the blue and purple light directly absorbed by chlorophyll, so the whole spectrum range that plants can use is 640 ~ 660nm + 400 ~ 500nm. Therefore, the effective spectrum of plant growth fill light should be red light and blue and purple light, and the color should be red or blue and purple.
Is plant growth lamp really effective for crops?
It can increase photosynthesis and accelerate plant growth
Has anyone ever heard of plant growth lights?
Plant growth lamps are special lamps and lanterns, which need sunlight in accordance with the growth law of plants. The plant growth lamps are a kind of lamps that use sunlight principle and light instead of sunlight to give plants growth and development environment.

After application testing, the wavelength of the plant light is ideal for plant growth, flowering and fruiting. General indoor plants and flowers, will grow worse and worse with time, the main reason is the lack of light irradiation, through the LED lights suitable for the spectrum required by the plant irradiation, not only can promote its growth, but also can extend the flowering period and improve the quality of flowers. And the application of this efficient light source system to the greenhouse, greenhouse and other facilities and other agricultural production, on the one hand, can solve the shortage of sunlight led to tomatoes, cucumbers and other greenhouse vegetables decline in taste, on the other hand, can also make the winter greenhouse eggplant and fruit vegetables ahead of the Spring Festival around the market, so as to achieve the purpose of counter-seasonal cultivation.

Misconception # 1: Lumens = Photosynthesis
Lumens is the number one indoor gardening myth that a proper method to determine the light generated by plant grow lights all the time. Measuring light lumens for photosynthesis is simply ordinary silly. Let's be clear: Lumen (scientific notation: LM) is a measurement of just how much light the human eye perceives. It does not, whatsoever, gauge the light that drives photosynthesis. Period. Put simply, lumens measure the overall amount of light visible to the human body that originates from a particular light.
Plants and humans evolve in the same light that comes from the sunlight. Yet human beings and plants use this light extremely in a different way. People consume to 400 nm and 700 nm in between the "visible variety", yet our eyes are concentrated on the 500-600 nm, primarily eco-friendly and yellow parts of the range. Plants have a totally various reaction to light, focusing their absorption around 400nm-500nm (blue) and also 600nm-700nm (red). They additionally take in some light in the visible spectrum in the rest of the UV as well as IR bands as well as non-visible light.
Measuring the light outcome of lumen growth is a blessing for the lights industry itself. Since makers of light bulbs focus largely on lights for human beings, they will certainly release light specs in lumens. Some countries call for bulbs to be ranked according to lumen result. Indoor gardeners have actually embraced this technique for measuring the brightness of their grow lights due to the fact that it is generally offered from the light maker (at the very least until the light begins website).
When it pertains to patio lights, it's time to quit considering lumens and also start thinking of "photon change thickness" (PPFD), which defines the density of photons reaching a particular location. PPFD is gauged in "micromoles (micro-moles) per meter2 per 2nd", which is a better measurement for light reception in plants than lumens. You need a quantum flux meter to determine just how much of the photosynthetically effective light power is actually reaching your plants. When testing LED plant expand lights, make certain to choose a quantum change meter that is created for LEDs, or your dimensions will certainly be off. Regrettably, these gadgets are extremely costly.
Myth # 2: Summertime to winter season, all periods
A valued yard writer lately covered this in one of one of the most preferred interior horticulture publications: "In [high-pressure sodium lights are] really red and also simulate the sun-induced blossoms of fall." HID light salespeople as well as hydropower shopkeeper also assert that MH lights are best for nutritional growth since they are "blue" like spring sunlight, while high-pressure sodium lights are best for blossoms due to the fact that they fall like "red" lights
This is the second most extensively held horticultural mistaken belief: the color of sunlight adjustments significantly in between seasons, and also this color shift causes blooming. Ask on your own: at midday, do you look blue in the springtime or do you flush a little in the loss day?
The "color" of light is established according to the proportion of Kelvin (K) with blue having a higher worth and red lower. The world looks strange if the light temperature of sunshine is anything also near the difference of 2000-2500K in between MH and HPS lights from the changing periods. Don't get me wrong: there is a seasonal shift in the shade of daytime due to the deepness of the sunlight's light that has to travel through the atmosphere prior to reaching the earth. Nonetheless, this change is small, 300-500K relying on where you live, which is a distinction that is nearly invisible to the human eye.
On the other hand, daytime shade most definitely moves across the time of day. Sunshine begins at concerning 2000K (orange) in the early morning, climbs up over 5000K (white) by midday, and after that hangs back to 2000K or lower by sundown. Daytime sky color temperatures can climb up as high as 8,000-10,000 K (blue) on a bright summer season afternoon.
Why is this so? Because indoor garden enthusiasts are shown that a change from "spring blue" to "dropping red" will certainly motivate blooming - simply put, will certainly trigger plants to move from the dietary growth stage to their flowering phase. This belief might be just how HID lights discover their way into indoor gardens downstream of the influence. Originally, only MH lights were available, and also using them for planting was the result of experience ... OK. Then, high-pressure sodium lights were introduced, as well as garden enthusiasts that attempted them found that these new lights significantly boosted the weight of the harvest. It was hypothesized that MH was much better for nutritional growth and also better for flowering with high pressure sodium lamps, and also the myth was born. It has actually ended up being a mainstream "truth": get any type of publication dispersed in hydroponic shops and also you will certainly find it. That does not suggest it's true.
Several gardeners make use of just one kind of HID light for their whole expand, including MH, HPS and CMH lights. Every one of these gardeners have any problem "flipping" their gardens from dietary to mushrooming/flowering. They simply change the length of the photoperiod at the time the lights are activated. Plants are day-long blossom delicate and also when their photoperiod adjustments, they get changes in light that can not be made use of as shade.
Myth 3: 90 watt LED lights can replace 400-600 watt HID lights.
Oh, exactly how you missed out on the preliminary enjoyable of LED plant grow lights! When LED plant grow lights were first presented, numerous suppliers made bold cases that a 90-watt LED plant grow light would certainly out produce a 400- or 600-watt HID. these cases were absurd, and they stay absurd too. LED plant grow light makers are generally excitable with their insurance claims, and also they "prove" that by growing tiny ice or lettuce, rather than light-starved crops (such as tomatoes, cucumbers, herbs, or flowers) interior garden enthusiasts generallyprefer.Testing reveals that these very early Screening exposed that these very early "90 watt" devices really drew only 54-56 watts of power on the wall surface, on average. With a couple of watts going to the power supply board on the cooling fan, these lights really generated less useful light than the 75-100 watt high pressure sodium lamps, without anything near to the 400- or 600-watt HID performance claimed by their makers.
At least the sector appears to have learned its lesson. Nowadays, most LED plant expand light manufacturers offer sensible power ratings as well as insurance coverage recommendations for their lights. This mix of much better, much more effective LEDs and extra effective light style is assisting to place an end to this myth. It would certainly be perfect for LED plant expand light suppliers to publish the power of their lights in micromoles at established elevation intervals so that we, their clients, can make a decision for ourselves just how much HID these lights can give ourselves instead of what we are really dealing with in our gardens.
Misconception # 4: LED plant lights have a strong lifetime
Because LED emitters have a 50,000+ hr life expectancy, which is about 10 years if made use of 12 hrs a day, a typical sales pitch is: "This could be the last plant grow light you'll ever before get." This pitch is planned to assist customers deal with the high expense of LEDs for grow lights. Unfortunately, it just doesn't work by doing this.
Although LED emitters have a long life-span, continuous technologies in light layout, such as secondary optics, much better thermal administration, and also better fixed LED emitters on the horizon, will certainly trigger lots of growers to upgrade to the newer, better doing light openings they've placed in their first LED grow lights in the previous one decade. So while "the last light you ever purchased" makes an excellent sales pitch, do not believe it. It's not real.
Misconception # 5: LEDs create little or no warm
The following most typical sales pitch for LED plant grow lights is that they generate little to no warm. When producers declare that LED plant grow lights create little to no heat, it leaves the knowledgeable garden enthusiast questioning if the supplier ever made use of one more point to take an image of.
Certain, LED grow lights create less warmth than CONCEALED expand lights, however there is still warmth, and heat needs to be taken care of. See for yourself: yard temperatures instantly after removing the LED grow lights off, much like a CONCEALED yard. No heat no chance!
Myth # 6: LED lights don't shed plants
One of the largest mistaken beliefs about LED expand lights is that they will not melt plants, regardless of how close they are placed to the plants. This myth is based upon the fairly reduced warmth output of the light as well as the idea that "the extra photons the better." Early LED expand lights, with their reduced result, could be positioned near to plants - pro like fluorescent lights, in many cases. Today's high-powered devices can conveniently go beyond limelight restrictions for plants.
When men are too close to the plant, LED expand lights can trigger photo-oxidation or "photobleaching". When this occurs, much more light is absorbed than can be processed by the plant. Those parts of the plant that are closest to the light are frequently the biggest flowers, however - turning white as their chlorophyll is destroyed. LED and also CONCEALED plant expand lights can bleach plants when used poorly, however the trouble is much less usual with HIDs, as their high warmth result usually creates gardeners to raise the light, getting rid of the hazard.
Misconception 7: Blue light boosts nourishment, red light is restricted to flowering
After their intro, some LED business carry out pitching just blue light nutrition growth, just traffic signal bright flowering. There are some lights on the market that make this case. With the myth of "90 watts = 400/600 watts", this technique might be suitable for low-light crops such as wheatgrass, yet light love plants need a fuller spectrum for typical growth.
