The Difference Between Artificial And Natural Light (Which One Is Better For Growing Plants?)

Plants can grow without sunlight, but it’s a different kind of growth.

In the wild, plants have evolved to survive in various environments. They thrive best when exposed to both natural and artificial light. However, most indoor plants do not have access to natural sunlight.

Artificial light provides the same wavelengths of light as sunlight and is used to mimic the effects of sunlight on plants. It is not only beneficial for growing plants indoors, but it is also used to help grow flowers, trees, and other plants that require natural sunlight.

But what is the difference between artificial and natural light? Which has the advantages and disadvantages? I will answer these questions and many more in this post.

What is Artificial Light?

Can Plants Grow Without Sunlight?

Many plants don’t need sunlight, and some plants thrive in artificial light. So, what exactly does “artificial” mean?

Artificial light can be anything from a fluorescent bulb to an LED lamp. All these things create their own kind of light, but they are different from the sun’s rays.

You should know that there isn’t any difference between how artificial lights work and how sunlight works. The main thing that makes them different is how much energy they use.

For example, a fluorescent tube uses less electricity than a regular incandescent lightbulb. But, it still creates its own unique type of light.

The same goes for LEDs. While they do use more power, the amount is very small compared to other forms of lighting.

So, what happens when you have a plant that needs sunlight? Well, it will just get weaker, which means your plant won’t grow as well.

What is Natural Light?

Can Plants Grow Without Sunlight?

Natural light is the light that comes from the sun. There are two types of natural light: direct light and indirect light. Direct light is the light that comes from the sun, and indirect light is the light that is reflected from the sky.

For plants to grow, they require energy from the sun. However, the amount of light that reaches the earth’s surface is minimal, and only about 10% of the sunlight that hits the earth actually hits the ground.

Plants absorb nutrients from the air and water and make their own food through photosynthesis. When light hits a leaf, it is absorbed by the chlorophyll in the leaf and used to produce sugar. The leaves then transfer this sugar to the rest of the plant, where it is used to build cells and form a new plant.

When plants are exposed to insufficient light, they will stop producing food and will eventually die.

To compensate for this, many hydroponic systems use a greenhouse or grow room to allow more light to reach the plants. These rooms are usually equipped with lights and fans to circulate air.

A greenhouse is usually a big structure, but a small one can also be built in your home. If you have a greenhouse, great! If you don’t have a garden, then you can still grow plants in a window box, and you don’t need a lot of space to grow hydroponically.

When you have a greenhouse, you will have both direct and indirect light. In a hydroponic system, you will have direct light as well as indirect light. The indirect light can come from a light fixture on the ceiling or from the sun itself.

The more direct light you have, the healthier your plants will be. In a greenhouse, the indirect light can be blocked by other plants or the greenhouse structure. 

Is Artificial Light Bad for Plants?

The question of whether artificial light is good or bad for plants is a bit complicated. What you are growing will really affect whether artificial light is good or bad.

A lot of people tend to think that artificial light is bad for plants. But, there’s actually no evidence to support these claims.

Plants require sunlight to grow and develop. However, they can still grow in the dark if the lights are on. It is important that you have the right light for each plant type and suitable for each plant’s growth ability.

Artificial lighting can be useful when growing in the dark, but it can also cause the plants to produce more leaves and stems than they normally would. This is because they are trying to make up for the fact that they are not receiving enough sunlight.

The ideal ratio of light to dark is around 6 hours of light and 6 hours of darkness. The more light you give to the plants, the more stems and leaves they will produce.

Artificial lights are very useful to help produce fruits and vegetables at a faster rate. They also make growing larger crops easier, allowing you to grow your plants indoors during the winter months. 

The Effects of Artificial and Natural Light on Plants

Can Plants Grow Without Sunlight?

Light is essential to all life on earth. We need sunlight to grow food, stay healthy and have energy. However, many people don’t realize that light can also be harmful. Keep reading if you’d like to learn more about how light affects plants.

We usually notice two different kinds of light when we look at the sun. One kind is visible light, and this type of light gives off a rainbow-like spectrum of colors. Visible light comes from the sun but doesn’t travel very far.

Another kind of light is ultraviolet (UV) light. UV rays cannot be seen with the naked eye, but they can cause damage to living things.

Artificial and natural lighting both affect plants. For example, fluorescent lights emit blue wavelengths, which may help some plants to grow faster. On the other hand, red and orange light can make leaves yellow or brown. In addition, too much light can stress certain plants.

In these cases, the plant may grow more slowly or even die. Light can also affect some insects, and some plants can become “phototoxic” when they are exposed to too much light. 

Are plants grown in the dark?

Most people who are new to hydroponics are often confused by the idea of growing plants without sunlight. If you want to grow a plant, you have to expose it to sunlight. The reason for this is that plants cannot photosynthesize without light. Without sunlight, plants don’t get the fuel they need to grow.

Hydroponics does not work without light. For hydroponic systems to function, a nutrient solution must be present. Without a nutrient solution, there will be no plants, as we discussed in our previous blog post.

If you are wondering why your plants don’t seem to be growing in your hydroponic system, it could be because there is no nutrient solution present. It could also be that your plants are growing in the shade. If this is the case, you can try placing your plants in direct sunlight for a couple of days.

How Do Plants Grow?

Sunlight is essential to plant growth, as we all know. But did you ever wonder how plants actually get their energy from the sun? The answer lies within a process known as photosynthesis. This is the chemical reaction in which light energy is converted into the food that all living things need.

Photosynthesis occurs when green pigment molecules absorb light. When this happens, they release electrons and form bonds with water. As a result, the hydrogen ions in the water are released.

Now, the oxygen atoms in the air react with these free electrons. And because the oxygen atoms have more electrons than the hydrogen ones, they become positively charged.

This means that the negatively-charged hydrogen ions can now be attracted to them. Once the two groups of particles come together, they create an electric current that powers a plant’s metabolism.

The amount of energy that the plant receives depends on the intensity of the light.

How Much Light Does a Plant Need?

Whenever you grow plants indoors, you must ensure that your house receives enough sunlight. For plants to thrive, they require a certain amount of light. If they don’t receive enough water, their leaves will wilt. This is why it’s important to understand how much light you should be providing for them.

Most indoor gardeners use artificial lighting to provide the right amount of light. You can also get creative by using different kinds of lights to create more natural-looking results. For example, you could hang a string of Christmas lights from the ceiling above a pot of basil.

A good rule of thumb is that plants need between four and six hours of direct sunlight each day. However, it varies depending on the type of plant you’re growing.

You may not realize that there are different ways to determine whether or not your plants have received adequate amounts of light. Check the leaves of your plants to find out.

The Cons and Cons of Artificial and Natural Light

Plants require sunlight to grow and thrive. However, too much sunlight can harm them.

In fact, plants can even die if they receive too much sunlight. This is why many people have plants in their homes. And they can even have plants in their offices. But, how should people decide whether to use artificial light or natural light?

The following are some of the pros and cons of each type of lighting.

Natural light


  • Plants love natural light, and it helps them to thrive. Plants grown in the dark tend to have smaller leaves and smaller fruits. Artificial lighting tends to be more expensive than natural light, but it also produces more consistent results.
  • The pros of natural light for plants compared to artificial light include: Natural light is always available. It is free. It is not as expensive as artificial light. It is a renewable resource. And it is a healthy resource.
  • The light from the sun provides the plants with a full spectrum of colors. Artificial lights only provide light in some specific color, so they can’t replicate the full spectrum of colors that plants need to grow properly.
  • Another pros is that plants grown in natural light require much less water than those that are grown in artificial light. This is because plants that are exposed to natural light can use sunlight to help them photosynthesize, which allows them to use less water.


  • It takes time to grow, and the plant will not mature until it is fully grown.
  • It can be difficult to control the intensity of natural light, and it isn’t always available.

Artificial light


  • Artificial light is a lot more convenient than natural light. It is available at any time of day, and you don’t have to worry about getting your plants outside in the dark. It can be used indoors or outdoors. It can also be used to provide a more even light.
  • Artificial light is also much more controllable than natural light. There are several reasons why artificial light is better for plants than natural light, including the fact that it is more consistent and intense.
  • Using artificial light at night can cause plants to grow more slowly, and they will not bloom as well.


  • Artificial light can be very expensive, and it’s not always the most energy-efficient form of lighting.

So, which is better?

Artificial lighting is a good choice for many reasons, but it’s important to consider your individual needs when choosing between the two. Artificial light may be the best option if you’re looking for a uniform environment for your plants.

However, if you need to control the amount of light your plants receive or you want to reduce your electricity bill, then natural light might be the best option for you.

One of the most important things to consider when choosing a lighting system for your indoor plants is the light spectrum. If you use too much of one type of light, it can have negative effects on plant growth.

When choosing between natural and artificial light, it’s best to look at the color temperature of the light. The color temperature of natural light is usually around 4000K, whereas artificial light has a color temperature of about 2700K.

In Conclusion,

There are many different kinds of plants that require sunlight to grow properly. Some of these include flowers, vegetables, trees, grasses, shrubs, etc. But did you know that there were other kinds of plants that could survive without sunlight?

For example, some types of moss live completely underground. And while there are a few species of lichens that can also exist in complete darkness, most of them need light to thrive.

Through this article, you may have understood how some of the world’s strangest and weirdest plants actually survive in total darkness.

One thing you should keep in mind is that some of these plants have been around for hundreds of years. So they must be doing something right!
