While plants will absorb a certain amount of energy from all colors of light, the absorption rate will greatly vary with the different colors, and so will the growth of the plants. More absorption equals more growth! The reason there is a variation is due to the different wavelengths of different colors of light.
Why do plants have different wavelengths?
Depending on how long or short the wavelengths are, the plants will trap in the energy accordingly.
Why do plants use blue lights?
Blue lights are also happily taken in by plants due to their short wavelengths and high energy potential. These lights are vital during the initial phases of plant growth as they allow the plants to produce more chlorophyll in their leaves, which facilitates them to absorb more light afterward.
What happens when chlorophyll is low?
Chlorophyll content in the leaves is reduced. As a lower amount of chlorophyll leads to a lower rate of photosynthesis, the growth of the plants becomes restricted , leading to unhealthy production of plant products .
What color light is needed for a plant?
While violet, blue and red lights are a must for the plants, shades of yellow and green are not as effective.
Why do plants grow bigger?
As the plants produce more food, they grow bigger in size and provide more plant products . But do all types and colors of light produce the same amount of yield? We will discuss that in the next few sections.
Why do LED lights vary?
These lights themselves vary due to several aspects such as the type of the plant, number of plants, and size of the grow tent, among many others. For instance, the LED light for 4×4 grow tent during a particular growth phase of the plant will surely differ from the LED needed for a 5×5 grow tent due to size variability.
What are the two types of light?
There are two types of light: Natural sunlight and artificial light. Let’s have a quick look into these.
How do plants grow?
Plants are commonly grown in greenhouses, which provide extra warmth and humidity by forming a barrier between young plants and the outside environment. This allows plants to thrive when outdoor conditions would be too harsh for them. Though greenhouses are classically built out of clear glass or plastic, there are some built from semi-porous netting. The term greenhouse does not just apply to structures that are green, though many greenhouses are covered in green, semi-transparent plastic. Plants require sunlight to grow, which they transform into usable energy in their chlorophyll. This experiment attempts to discover whether the chlorophyll in plants can transform light into energy when certain colors of light are missing from the spectrum.
What is a greenhouse made of?
Though greenhouses are classically built out of clear glass or plastic, there are some built from semi-porous netting. The term greenhouse does not just apply to structures that are green, though many greenhouses are covered in green, semi-transparent plastic.
How to make a mini greenhouse?
Start by separating the foot-long pieces of 1”x1” boards into groups of 10. You will need 10 pieces to construct each greenhouse. Use two nails to attach the wood together at each corner.
Do greenhouses need cellophane?
One greenhouse will need to be covered in clear cellophane. This will be your control.

What Is the Electromagnetic Spectrum?
The electromagnetic spectrum includes x-rays, microwaves, infrared, ultraviolet light, gamma rays, visible light, and radio waves. All are types of light that travel in waves emitted by the sun.
What Is Photosynthetically Active Radiation?
Photosynthetically active radiation (PAR) is the range of radiation that plants can use in photosynthesis. All PAR is visible light ranging from 400 to 700 nanometers, including violet, blue, green, yellow, and red.
What Color Light Is Best for Plants?
Most of the colors on the visible light spectrum affect plant growth, but red and blue lights are the most beneficial. However, these aren’t the only colors your plant uses to stay healthy, and it needs all light energy in the PAR range to optimize plant growth.
How Do Plants Respond To Positive Phototropism
Phototropism in Plants Objective: Observe how plants respond to light and how they respond when there is a limited source of light. Introduction: Phototropism is the way plants respond to light, which dictates whether the plant will lean towards the light which is positive phototropism, or away from light, which is negative phototropism.
Green Light Lab
Title: How Different Colored Lights Affect the Growth of Plants Introduction: This experiment had multiple objectives. The first objective was to establish what colors of the light spectrum photosynthesis uses.
Disadvantages Of Suncreen
Sunlight has UV photons that we humans can’t see but can damage our skin. There are UVB rays and UVA rays, UVB rays are short wavelengths and don’t get deep into our skin so they are the main cause of sunburn + skin cancer but UVA rays have a longer wavelength and go deep into the skin and are the cause of early aging.
Etiolation In Plants
1. Introduction Etiolation is a process which occurs in plants which are grown without light. This process increases the chance of a plant to reach the light and to actually photosynthesise.
Acid Rain Persuasive Essay
Some people call it acid deposition because they say it is a more precise name due to the fact that acid rain isn’t only rain, it can fall as rain, snow, sleet, hail and anything else. Acid rain has been formed because as we release harmful gases into the atmosphere, we are lowering the pH of precipitation, creating acid rain.
How Ultraviolet Waves Cause Skin Damage
Scientist believes getting older can also cause skin damage. Some ways you can prevent skin damage is putting on sunscreen and staying out of the sun. Ultraviolet waves are waves that are caused by radiation. Ultraviolet waves can be useful and harmful, some ways they can be harmful is by causing skin damage, damage to the eye, and also damage
Personal Narrative: My Skin Pigmentation
Also, there's a limit of protection that melanin can provide and that limit is higher in people with darker skin. The problem with someone's skin "getting darker" is there can be some damage that is being done. Some of the damaging effects of UV radiation is it can damage you're DNA, it can promote burns, and most commonly it promotes skin cancer.
What is the process of photosynthesis?
The process of photosynthesis where plants make their food requires the use of light. Also, chlorophyll is responsible for the green pigmentation of leaves and stems. Chlorophyll requires light to transform carbon dioxide into food and this is done by the energy from light.
What color light is best for seedlings?
Having mentioned most of the colors your grow light will produce; now we are wondering what the best color that will affect the growth of plants? The best and most important colors for the development of your plant are the red and blue light colors. Blue light is ideal for the early plant stage such as seedlings.
What is violet light?
Violet light or purple light is an additional light that your plant will benefit from. These colors have the shortest wavelength and high energy which enables the plant to be able to absorb them well. The light energy in violet color results in sweet aroma, great plant color, flavor booster in vegetables and fruits.
What is the best light for plants?
Red & Blue Light Combination. The red and blue light are a great combination and they are needed as your plant matures. They are especially required for both the vegetative and flowering stages. This red and blue light enhances the production of more leaves and crops.
Why do plants use blue light?
Blue light is easily assimilated by plants which they convert to energy to attain maturity faster. A blue light will also enhance the quantity of chlorophyll that is produced by your plant.
What color of light do plants use?
Some Important Color Of Light Used By Plants. Blue, red, green, yellow, and a couple of other light colors are essential in the plants’ life cycle. Let’s take a look at some of this color of light and see how they affect the growth of your plant:
Why is blue light important for plants?
Blue light has a short wavelength and high energy in the color spectrum which makes them easy to absorb by plants. They are very important for the early plant stage such as seedlings and some seeds may not germinate if this blue light is absent. This is the light to be used when your plants are beginning to sprout.
