How does red light affect plant growth

Red light on extension growth. Many plants grown under only red light, such as plants grown indoors under only red LEDs, have a stretched, elongated appearance; the leaves are thin and large and plants become tall. In most cases, plants grown under only red light do not have desirable growth characteristics. However, when a relatively small. With cutting-edge spectrum variable lights, you can change the quality, flavor, potency, and yield of your crop just by adjusting the light spectrum over the course of the growth cycle. Red light inspires flowering. Blue light ensures tighter internodes in vegetation and increases the concentration of oils and resins during flowering Far-red, blue and red light have a synergistic effect. Impact of far-red light on plant growth. Zhen and her colleagues trialed the impact of far-red light on canopy photosynthesis of over a dozen plant species, including greenhouse leafy greens, cucumbers and tomatoes and field crops, including potatoes, rice, wheat and corn Arbitrary changes in light duration will affect the growth of the plant. Spectrum: Plants need both red and blue spectrum light to flourish at different stages of growth and to bloom. In an indoor grow system, you will have to pick artificial grow lights capable of fulfilling all three factors

  1. ation, root growth, and bulb development. Red Light or Blue Light for Plants
  2. Among sunlight, red light is most absorbed by chlorophyll and has the greatest effect, followed by yellow light. The assimilation efficiency of blue-violet light is only 14% of that of red light.
  3. Blue and red light, which plants absorb, have the greatest effect on plant growth. Blue light is responsible primarily for vegetative (leaf) growth. Red light, when combined with blue light, encourages flowering. Plants look green to us because they reflect, rather than absorb, green light
  4. ation, bulb formation, root development, dormant periods and the appearance of fruits and flowers. The fruits and flowers are actually triggered by plant hormones that begin the process
  5. Some green light is retained by your plants for photosynthesis; leaving this part of the spectrum out altogether can negatively affect the growth of the plants. Yellow or White Light Yellow light isn't the most effective part of the spectrum for plant growth, but it is still present in sunlight and so it's still important to ask the.
  6. When a plant perceives the red light, Pr transforms into Pfr, and if a plant receives the far-red light, it's Pfr goes back to Pr. Pfr is important because it triggers plant growth, but it slowly reverts back to Pr over time when the plant is located in the dark
  7. Background: The relationship between light and plant growth can be demonstrated by exposing leaves to various colors of light. Light supplies the power to carry on photosynthesis, the food-making process in leaves. But the spectrum of light most utilized by a leaf is limited to three distinct colors, red, blue and yellow

The plants were grown under red and blue LED lights. This plant experiment studies the effects of different types of lighting on plants such as radishes and leaf lettuce. Photo Credit: NASA/Frank Ochoa-Gonzales › View Larger image. Image above: Red leaf lettuce plants were also harvested from a plant growth chamber grown under red and blue.

Where gardeners may run into trouble is with grow lights that don't give off sufficient quantities of red or blue light. According to Greenhouse Product News, red light stimulates plant growth. In.. the greatest effects on plant growth. Blue- light photoreceptors absorb wavelengths of blue light and trigger a number of reactions in plants. Blue wavelengths affect phototropism, the opening of stomata (which regulates a plant's retention of water), and chlorophyll production. Phytochromes absorb mostly red light. Red wavelengths se According to Planta, increased infrared waves can affect the speed at which plant stems grow. A short exposure to far infrared light increased the space between nodes when the exposure occurred at the end of an eight-hour light period. Exposing the plant to ordinary red light reversed this effect. A combination of far red and red light produced. The purple and blue light wavelengths, 400 to 490 nanometers, stimulate the vegetative growth phase while the yellow-orange-red wavelengths are used for flowering and fruiting. You emerald lovers probably already know that the plant doesn't use the green wavelength and reflects it back to our eyes

Can far-red light improve plant growth? - GLAS

If artificial light is the only source of light for growing plants, the quality of light or wavelength, must be considered. Plants require mostly blue and red light for photosynthesis, but for flowering, infrared light is also needed. Incandescent lights produce mostly red and some infrared light, but very little blue light Effect of red light on plant growth Plants are sensitive to red in the light spectrum, a sensitivity that arises from the plant having what is called a red light photoreceptor. The receptor is a blue-green pigment termed a phytochrome present in the cells of a plant. You might think of phytochrome as an eye that only senses red light

How Light Affects Plant Growth - What You Need to Know

(b) Pigments in the plant do not absorb green light, they absorb other wavelenths that are needed for growth. The green cellophane is absorbing wavelengths of light that are needed for plant growth, so the plant under green cellophane grows more slowly. 4. Chlorophylls are the major group of pigments common to all photosynthetic plants How Light Affects the Growth of a Plant. All things need energy to grow. We get energy from the food we eat. Plants get energy from light through a process called photosynthesis. This is how light affects the growth of a plant. Without light, a plant would not be able to produce the energy it needs to grow. What Kind of Light Do Plants Need. Shading by sunlit leaves causes a low red (R) to far-red (FR) ratio that results in a low phytochrome stationary state (PSS). A low PSS induces an array of shade avoidance responses that influence plant architecture and development. It has often been suggested that this architectural response is advantageous for plant growth due to its positive effect on light interception

Blue light, for example, helps encourage vegetative leaf growth. Red light, when combined with blue, allows plants to flower. Cool fluorescent light is great for cultivating plant growth indoors. Knowing that different colors of light can affect what a plant does is important in a world that depends on plants for food Red light. Plants are sensitive to the color red in the light spectrum, a sensitivity that arises from the plant having what is called a red light photoreceptor. The receptor is a blue-green pigment called a phytochrome present in the cells of a plant. You could compare phytochrome with an eye that only senses red light

Plants Respond Differently to Far Red Throughout the Growth Cycle. The effect far red has on your plants changes depending on the maturity level of your crop. We'll get into the details in a moment, but the headline is this. When your plants see more far red light than red light, they think they're in the shade. It's that simple Blue light, red light and green light each have a different effect on plants. Blue light produces more lush greenery. Blue light is necessary for plants to regulate plant growth, as it helps to create strong stems and also helps create the chlorophyll necessary for plant processes Red light is special in that it can deliver high growth to a plant, but without the limiting effect of blue that obscures the chloroplast to protect it from high-blue midday sun. Therefore red is very efficient at producing fast growing tall and strong plants and indeed produces some of the most impressive growth rates of height and stem width.

Red Light Or Blue Light For Plants - Effects Of Red And

  1. Blue light can be used to stimulate vegetative growth and prevent shorter-day plants from flowering during their propagation stages. Red light can be used to induce flowering and lengthen the internodes to produce plants with longer stems and bigger flowers. Roses are an example. Far-red radiation can be used to control the photoperiodism of.
  2. It's important to note light spectrums affect plant growth differently depending on things like environmental conditions, crop species, etc. Typically, chlorophyll, the molecule in plants responsible for converting light energy into chemical energy, absorbs most light in blue and red light spectrums for photosynthesis
  3. LED Lighting and its Effect on Plants, Growers and the 24 and 32 percent blue light along with varying ratios of red and a constant level of white light. by LEDs leads to the use of significantly less water increasingly important in times of record drought and using light to steer plant growth instead of plant hormones leads to less.
  4. The plants will grow best under the red and blue light, as the hypothesis predicted. The green light will hinder plant growth as plants naturally reflect green wavelengths of light and therefore, the plants absorb absolutely no light
  5. In effect, light intensity can vary depending on the type of color used as well as the wattage amount contained in a bulb. The energy intensity provided by red light stimulates overall growth throughout the plant body, while blue light helps to regulate growth rates within the leaves, stems and flowers
  6. nanometers. BLUE light carries a higher energy signature then RED light does and that higher energy with a shorter wavelength should provide the plants with a better environment for growth. Blue light has a wavelength that is shorter in the visible spectrum as compared to red light and has a higher energy. (eosweb.larc.nasa.gov) Chlorophyll is.
  7. Additionally, research has shown that exposing plants to UVA light can also inhibit mold growth and fungal development. Far-Red and Infrared Light. On the far end of the spectrum (>700nm) you find far-red and infrared wavelengths of light. Far-red and infrared light have very long wavelengths, and very little energy

The Effect of Light on Plant Growth and Development

Environmental Factors Affecting Plant Growth OSU

Using limited spectrum lights are adequate for indoor growing. Blue light and red light will successfully grow a cannabis plant without any problems. Using grow lights that provide a fuller spectrum of visual light will have an affect on the plant and usually results in a bigger yield Red light devices were used to limit bone and muscle loss in space. They also discovered that certain spectrums of red light allowed plant growth (for food) in space. Does it get hot? Can you tan with it? No and no. It gets pleasantly warm but not hot. Red light is a different wavelength than UV light. It does not produce any tanning effect How do different color filters affect plant growth? Question Date: 2000-01-24: Answer 1: Your question is a very good one becauseplants absorb light at very specific wavelengths to obtain energy.. In particular, chlorophyll absorbs blue and red light while allowing green light to be reflected (or transmitted)

However, beyond just supplementing the sun, by carefully choosing the colors of light plants are given, we can control how they grow. Plants given low light intensity levels or excessive red light. Red Light: More red light tends to induce more biomass growth and stretching. Red light is often applied to bulk up plants in early development or to stretch plants when longer internodal spacing is desired. Blue Light: Higher ratios of blue light are a powerful tool for improving plant quality. Improvements to biochemical processes often occur. Is Far Red beneficial for indoor growing? We look at the most recent studies and technology to determine if we should add far red to our grow light spectrum.

IBSL2 Biology Lab - How does light color affect plant

Video: Red & Blue Light Effects on Plants eHo

The same type of plants that grew in the same exact conditions except the color of light absorbed, reached different heights. Different colors of light cause differences in plant growth. If a plant grows under red light, then it will grow the most. If a plant grows under green light, then it will grow th Does the Color of Light Affect Plant Growth Biology Projects, Biology Science Fair Project Ideas, Biology Topics for CBSE School,ICSE Biology Experiments for Kids and also for Middle school, Elementary School for class 5th Grade,6th,7th,8th,9th 10th,11th, 12th Grade and High School , MSC and College Students Why does a plant need light? Every plant, regardless of the size or type, needs light to survive. Plants use a process called photosynthesis to break down food in the form of nutrients in the soil. Plants get energy to start the photosynthesis process through light and without light the plant would be unable to turn food into energy

Various color spectra of light help plants to achieve different goals during their growth stage. For instance, blue light is best when it comes to enhancing vegetative leaf growth whereas red light, when mixed with blue light, comes in handy during the flowering stage of the plant Photoperiodism requiring visible red (625-760 nm) and infrared (760-850 nm). The role of light in photosyn-thesis and the conversion of this radiant energy to a chemical form in sugars that trees can use is well known. The role of day length or photoperiod in control of vegetative growth and reproductive activities may be less appreciated Thus, the effect of alternating red and blue light on plant growth and the underlying mechanisms remain to be clarified. If alternating red and blue light can enhance plant growth compared with simultaneous red and blue light and/or fluorescent lamps, it can also reduce electricity costs by shortening the time to harvest (Ohtake et al., 2015) While the impact of different light wavelengths on plant growth is fairly well established, their effect on cannabinoid production is still rather unclear. Back in the 1980s, the first proper study on the subject found no difference in THC content between plants that had been grown under normal daylight, or daylight that had been filtered red. Four Factors Affecting Plant Growth. According to the Oregon State University Extension Service, light, water, temperature, and available nutrients are the four things that affect plant growth the most.You may wonder where soil fits in this discussion. Plants can grow without soil using a gardening method called hydroponics, but they cannot grow without nutrients

Therefore, the vegetative growth of cress was substantially affected by red and blue lights, resulting in the enhancement of the plant's biochemical features compared to control condition via. Arrays of blue (B, 400−500 nm) and red (R, 600−700 nm) light-emitting diodes (LEDs) used for plant growth applications make visual assessment of plants difficult compared to a broad (white, W) spectrum. Although W LEDs are sometimes used in horticultural lighting fixtures, little research has been published using them for sole-source lighting

How the Color Spectrum Affects Plant Growt

  1. How does red light affect photosynthesis? Why? Plants grow best in bright light. How do you define bright light? How do you define the best growth? Plants grow good in green and blue light. How will you test good growth? Plants on an average will grow an extra 2 inches in blue light than red light
  2. If a plant is exposed to red light during the dark period, it will wake it up because it thinks day is happening. Blue light also affects the plant at night by messing up its circadian rhythms, though blue light alone likely won't stop the plant from flowering. These processes helps the plant set itself on an internal clock
  3. well, any light you can get ahold of emits white light. this means light from all spectrums. so, in order for the light to be safe during dark cycle, you want to filter the light, from either green glass or green plastic. this makes sure any light passing through the material comes out at a certain wavelength safe for dark cycle of plants. using a 7up bottle, cut using 7 layers on top of each.

How Different Colors of Light Affect Plant Growth - Grob

Do Different Colors Of Light Affect The Plant Growth. Abstract: Light from the Sun is a full spectrum of different wavelengths of light.Scientists refer to this light as white light. When the wavelength of visible light changes, so does the color seen by the eye. The shortest wavelengths visible to the human eye are violet (400 nanometers) Understanding the Role of Light in Plant Growth. All green plants need light to process food in a process known as photosynthesis. Special cells in the plant leaves convert the energy in the light into sugars, while giving off oxygen as a by-product. No wonder it's so refreshing to sit in a room full of green vegetation Download: Let There Be Light Overview: Students will learn about how light is important to plants, and how both quality and quantity of light affect plant growth. Grade Level/Range: 4- 8 Objective: Students will: Learn about variations in light quality and quantity; Design and conduct experiments using grow lights to demonstrate the impact of variations in light on plant growth How does light color affect plant growth? Question Date: 2012-02-22: Answer 1: As you know, plants get their energy from light, but you might not know that different colors of light have different energy levels. Think about the colors of a rainbow. All of these colors are in white light

How Light Affects Plant Growth Science project

Plants use sunlight to make energy. The process by which they do this is called photosynthesis. Chlorophyll in the plant is the pigment that absorbs light. Light is made up of three different colors: red, blue and green. The reason that green plan.. The Advanced Platinum Series P150 is without a doubt an impressive lighting system as it's one of the few lights that actually does come close to offering a full spectrum of colors for your plants. This light operates on a 12-band spectrum ideal for ensuring your plants have healthy growth throughout their lifecycle If the plant is mainly illuminated by the far red light of 730nm, the plant will feel as if it is blocked by another higher plant to accept lighting from sunlight. so the plant will work harder to break through the blocking, which is to help the plant grow taller, but does not necessarily mean that there will be more biomass

The effect of red, blue and white light on plant growth

Effect of red light night break (NB) on tomato growth, development, and fruit yield. Discussion Previous studies on stem elongation kinetics indicated that stem elongation was not constant during a 24 h day/night cycle, in many plant species, stem elongation rate was higher in dark conditions than in the light ( Bertram and Karlsen, 1994. In plants, the phytochrome photoreceptors detect red and far-red (near infrared) light. Yang et al. (1) show that loss of phytochrome results in a general risk-averse strategy to growth. Instead of allocation toward growth, more resources are allocated toward resilience, and at the heart of this change in strategy there is a change in.

Bae, Hanhong, Response of plant growth and development to different light conditions in three model plant systems (2001). alignment can adversely affect reproduction. red light most strongly and have important roles in light-regulated vegetative an The absorption of the light spectrum is specific to plants. Red light plays an important role in controlling chloroplast, stem, petiole growth and reproductive system function, while blue light. Blue light can promote the growth of green leaves.Blue light combined with red light helps encourage the flowering of plants . blue light can increase the growth rate of plants. violet have an effect on the color, taste and aroma of plants. ultraviolet light(<400nm) UV-A(315nm-400nm

The plants use red and infrared light to regulate stem growth and flowering response. Plant cells produce a chemical called a phytochrome, which has two versions. One version, PR, is sensitive to red light (660 nm). Red light converts PR into PFR. PFR signals the plant to grow short stocky stems and also helps the plant grow into specific shapes The experiments confirmed that both blue and red LEDs have a positive effect on the accumulation of antioxidant phenolic compounds and lettuce growth, respectively. Red light irradiation in the. Measuring the effects of light color on photosynthesis is a fun and simple experiment for middle or high school students. By growing the plants beneath color filters, you can determine which color of light produces optimal growth. Visible light is a form of electromagnetic radiation with wavelengths. The eye is a complex organ that naturally tries its best to compensate for varying lighting conditions, and LED grow light spectra may not always appear natural to humans. If lighting conditions for the human eye change (e.g. going from a LED lit growth environment to natural daylight), colour perception may be temporarily affected while. panel. The red panel, in contrast had the least interference with the PAR, and this was reflected in the greater slope, and in fact, the growth was greater than the control value. One implication of this study is that it is possible to duplicate, in a general way, the effect of Aquashade® and limit the amount of PAR light of plants, an observatio

How well does photosynthesis occur in yellow light? - Quora

The scientists found that the intense light from red light-emitting diodes (LEDs) helped promote growth and photosynthesis of plant cells. Red light was then studied for its potential application. Takeaway: In horticulture, red and blue wavelengths were thought to be the only part of the spectrum that drove photosynthesis because chlorophylls are receptive to those colors. New research now reveals that previously dismissed green light can also drive plant growth. Fluence Bioengineering's chief innovation scientist Dung Duong explains the new data

· Constant light vs. Realistic light vs. Minimal light · Amount of light Dependant Variable~ · Height (Of the plants) Unit of Measure~ · Centimeters Constant Variables~ · Type of plant · Type of light · Type of soil · Amount of soil · Amount of water · Temperature of roo As the Full Spectrum light has 45% green light it clearly shows that the green light is contributing to plant growth. Otherwise the yield would be at least 45% less than the RED grow. The leaf colour, thickness and overall look of the lettuce was much better with Full Spectrum light compared to the other grows The explanation of how light affects some seeds and causes them to be in a state of readiness for germination and yet prevents other seeds if necessary from germinating is highly complex. Suffice it to say that it is mainly the light's effect upon a plant pigment called phytochrome within the seed Red light helps during the early stages of a plant's life by assisting with seed germination, bulb development and root growth and is also responsible for helping a plant flower and/or produce fruit Why is the color temperature of a grow light important? Color affects plant growth in different ways. Blue light is necessary for vegetative growth while red light is needed to promote flowering and fruit production. The color temperature of a grow light helps you understand if the overall output of the grow light trends towards blue or red

I read some place that plants need more red artificial light because it is the color of heat. It also said that artificial blue light was a cool color. Plant Growth and Light Color - Some Answers from Others. Jenni (a former student of SAS, a China located international school): The color of light does affect plant growth How to grow plants indoors? Experiment on testing the rate of growth of a plant using different light environments indoors. Our hypothesis is if we use a fluorescent light bulb then the plant growth would be higher in quality (height and healthiness) because it supplies better supplemental light and the plant has a better chance of survival compared to the incandescent light bulb Hello! My name is Grace and this is my science fair project for 8th grade! My science fair project tested whether the amount of light introduced to a plant affects the plant's growth in height. I tested with 6 hours, 12 hours, and 24 hours of light on nine different pots containing three seeds each A low red to far-red ratio and consequently a limited amount of red light at the beginning of the night is important for the flowering of short-day plants; Far red light alone does not regulate flowering; Green light is beneficial for the photosynthesis, although it does not affect the flowering or plant developmen Introduction. Light is the original source of energy for plant photosynthesis and growth. A wide range of signals and information for morphogenesis and many other physiological processes is triggered by light (Chen et al. 2004).Different characteristics of light such as spectral composition (wavelengths), intensity, duration and direction can influence plant growth and development

The fact that far-red light has precisely the contrary effect to that of red light makes it unsuitable as a light for growing. The traditional light bulb is a rich source of far-red light. Ultra violet light (UV) also influences plants. As with blue light, plants perceive this colour using the cryptochrome photoreceptor Light leaking into the grow-op when the grow lights are off will stress plants and disrupt flowering. This can stress a female plant into an intersex plant. Street lighting can confuse outdoor photoperiod cannabis plants and prevent them from flowering. Only a green bulb can be used if you must tend to plants or enter the garden during the dark.


UVR8. The effect of UV-B radiation on plant growth is dual. High fluence UV-B exposure causes photodamage, but low fluence UV-B contributes to photomorphogenesis and increases the resistance to herbivorous insects and pathogens (Ballaré et al., 2012; Galvão and Fankhauser, 2015).UV-B (280-315 nm) is perceived by UVR8, which uses a structure based on tryptophans and a complex salt bridge. plants use visible light (mainly blue and red light) as 'food' -- not so much green light, which is why they reflect green away, and look green to our eyes. They also happen to reflect near infrared light (which is just beyond red light, but not visible to the human eye) Controlling plant height without the use of plant growth retardants is one of the goals in future production of potted plants. Light quality with a low red to far-red ratio (R:FR) increases plant height. In this trial, the effects of light quality [R:FR ratio of 0.4, 0.7, and 2.4 (R = 600-700 nm, FR = 700-800 nm)] at the end of day were. ↑Sunlight does not affect snow melting. ↑ MC-217420 ↑ Sunlight does not affect ice melting. ↑ MC-217424 ↑ For growth, the relevant light level is that in the block above the plant. The growth of pumpkins or melons from a stem checks the light above the stem, not the block where the pumpkin or melon grows

Effects of Light on Seed Germination and Plant Growth

2. Artificial light sources for photosynthesis. Artificial lighting should provide plants with energy and information required for development. For this purpose, fluorescent lamps, particularly those having enhanced blue and red spectra (i.e. cool fluorescent white lamps), are widely used in growth chambers, together with additional light sources to achieve the sustained photosynthetic photon. Halogen only emits red light, so you'll need a source of blue one to ensure plant growth. The biggest drawback here is that running costs are almost the same as incandescent bulbs, so it gets expensive. Moreover, it's not the most efficient system for plant growth. The halogens are rare these days and they consume much more electricity than. My light was white LED but the fish and plants hated it cos it was too bright & harsh and algae grew like weeds, so contacted my aquarium supplier who suggested using the plants version LED which is from Ciano who produced my aquarium. It is LED with alternating 3 x red/1 ultra-violet that is 75cm long The plants and fish love it...and no algae whatsoever Night time I use green/blue tiny LED's. THE IMPORTANCE OF BLUE LIGHT. The use of red LED light to power photosynthesis has been widely accepted for two primary reasons. First, the McCree curves (Sager and McFarlane, 1997) indicate that red wavelengths (600 to 700 nm) are efficiently absorbed by plant pigments; second, early LEDs were red with the most efficient emitting at 660 nm, close to an absorption peak of chlorophyll Plants require light for optimum growth and development, but the three different aspects of light, quantity, quality and duration, also have a significant influence on growth. A plant under natural conditions receives light from the sun; the amount, quality and duration greatly depend on the season of the year, hour of the day, geographical.

Plants absorb mostly blue and red light (think of the colours present in a rainbow, plants use two particularly) in order to grow and flower. Blue light generally stimulates growth, while red light is important for growth and flower production. T5 HO tubes are available that produce colour values based on the Kelvin scale (K) The imagined audience is simply a student who has asked the questions: In what ways does light affect plant growth, and how does it do it? The book is limited to aspects of photomorphogenesis. Photo­ synthesis is only considered where its pigments impinge on photo­ morphogenic investigations, or where its processes provide illustrative. Photomorphogenesis is also an important concern. This deals with the way plants grow and develop in response to various frequencies of light. For example, far-red light can play a major role in plant development 8. Specifically, the ratio of red to far-red can signal plants to grow in an elongated fashion Plants growing outdoors, in greenhouses or close to windows are exposed to a balance of wavelengths of light from the sun, including the blue and red light that plants need. In settings where plants receive little or no natural light, additional light from artificial sources must be provided for adequate plant growth

The Effect of Infrared Light on Plant Growth Hunke

Red LEDs produce light that's 10 times brighter than the sun's rays. They also learned that this intense light helps energy metabolism in plant cells and promotes growth and photosynthesis This LED fixture does not provide sufficient lighting for demanding red plants or at least not enough to stimulate explosive growth rates (red plants, for example). Following these thoughts, I would run the grow light over my medium-depth fish tanks that are very heavily planted but do not contain super difficult aquatic plants Q. How quickly can red light therapy remove my scars? Ans: Depending on ones age & condition of their skin, red light therapy affects differently. Usually, effective results can be observed between 8 to 12 weeks. Q. Does red light therapy help with acne & surgical scars In a two-year clinical trial, cancer patients undergoing bone marrow or stem cell transplants were given a far red/near infrared Light Emitting Diode treatment called High Emissivity Aluminiferous Luminescent Substrate, or HEALS, to treat oral mucositis -- a common and extremely painful side effect of chemotherapy and radiation treatment

How Does Light Affect Plant Growth? Epic Gardenin

Incandescent Light (basic light bulb) and the Improvement of the Halogen Light. A CRI of 100 has a heavy red spectrum. The color temperature is 2700 K for incandescent light and 3000 K for halogen light. This type of lighting should only be used as a supplement for good plant growth due to the increased development of heat. Fluorescent Light The one with the biggest growth was plant under the red light, followed by a tie between the white light and blue light and last was the plant under the green light. CONCLUSION: The purpose of this experiment was to determine which color light the plant would grow best under. The hypothesis was that if a plant grew under a green light, then it. Light with wavelengths shorter than 400 nm is in the ultraviolet region and therefore invisible, whereas light with wavelengths longer is 700 nm is in the infrared region and is also invisible. The vital rays for plant growth are blue-light at 450 nm, red light at 650 nm, and far-red light at 730 nm
