Light intensity influences the manufacture of plant food, stem length, leaf color and flowering. Generally speaking, plants grown in low light tend to be spindly with light green leaves. A similar plant grown in very bright light tends to be shorter, better branches, and have larger, dark green leaves.

How does light affect plant growth experiment results?
Plants deprived of light will lose their color and die. The shoots exposed to “limited/no” sunlight had a yellow/white color due to the fact that photosynthesis could not occur. The lack of sunlight stunted photosynthesis and therefore the sprouts were not able to produce the chlorophyll needed to create a green color.
Do lights help plants grow?
Sunlight is the perfect balance of wavelengths necessary for plant growth and blooming, but you can also use artificial light to help your plants along. In fact, low-light foliage plants (such as pothos and peace lily) can grow quite nicely in windowless offices with enough artificial light.
What color light is best for plant growth?
Different color light helps plants achieve different goals as well. 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.
What color light is best for plant growth experiment?
It was thought that the green light would cause the plant to grow faster since it is a green plant. The color lights used were green, red, blue, and white.

| Before | After |
|---|---|
| Green Light | Doesn't have as many leaves as the other plants |
| Blue Light | Doesn't look as healthy as other, brown edges on plants |
Should I run my grow lights at night?
Like the sun's cycle, it is unnecessary to run grow lights around the clock. Yes, some plants need more sunlight than others. ... A good general rule of thumb to remember, if your plant is flowering or a vegetable it needs 12 to 16 hours of light in a day and 8 hours of darkness to rest.
Can plants feel pain?
Given that plants do not have pain receptors, nerves, or a brain, they do not feel pain as we members of the animal kingdom understand it. Uprooting a carrot or trimming a hedge is not a form of botanical torture, and you can bite into that apple without worry.
Will plants grow under normal LED lights?
Yes, you can use a normal LED light to grow your indoor plants since all of the plants under this category can thrive in artificial light. However, the growth and development of your plant may not be as good as natural lighting or other artificial light sources with specific colors.
Do red and blue lights help plants grow?
Plants that receive plenty of blue light will have strong, healthy stems and leaves. Red light is responsible for making plants flower and produce fruit. It's also essential to a plant's early life for seed germination, root growth, and bulb development.
Why do plants grow best under blue light?
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. ... In other words, the chlorophyll in the plant absorbs the red and blue light much more readily than the green light.
Does caffeine affect plant growth?
Caffeine, a chemical stimulant, increases the biological processes in not only humans but plants as well. ... Studies involving the use of caffeine on plants have shown that, initially, cell growth rates are stable but soon the caffeine begins to kill or distort these cells, resulting in a dead or stunted plant.
