Can A Regular Light Bulb Help Plants Grow

Last Updated on October 29, 2022 by Cinthia

Lights are essential requirements for successful indoor hydroponics farming. Now, if you’re wondering if a regular light bulb can help plants grow, we will let you know in this article.

Compared to the standard grow lights, regular grow lights are affordable and easily accessible. But do they produce the same effect as the standard grow lights? Let’s find out.

Can A Regular Light Bulb Help Plants Grow?

The answer is yes, a regular light bulb can help plants grow: but and in some cases, we would say no.

Although regular light bulbs for plants do not produce a full light spectrum, they can still help supply light for your indoor plant growth.

A regular light bulb can help plants that are grown in a small-scale garden or houseplant. They are especially ideal for starting just a couple of plants.

The most important thing when it comes to using a regular light bulb is to ensure your plants are getting enough light for growth. There are some signs that your plants will show if they are not receiving adequate lights.

Signs your plants will show include tall plants with weak stems, the green coloration of leaves may become lighter, and growth may be slow. If you notice these signs, it’s an indication that you need to provide your plants additional light or stronger light.

However, if you’re growing regular houseplants then any regular light bulb is just fine.

1.    Regular Incandescent Light

The incandescent bulb has been around for ages and they were the first design invented. They work by the passage of light through their small strand of metal that lights up as electricity pass through them.

The incandescent bulbs are regular light seen in most homes. Their power consumption is high and the heat they emit is usually a large quantity of heat. This makes them inappropriate for fragile seedlings and generally most plants.

They are pretty affordable and may work for your growing plants, but their downside outweighs their advantages making them unsuitable for plants.

However, if you wish to use an incandescent bulb, ensure you position them far from your plants so the heat does not burn your plant. You can put your hand for a few seconds close to your plant and see if the heat is moderate or not and adjust accordingly.

Also, it will require you to always move the light up and down between plants to moderate the excess heat they emit. Now moving the light further away from the plant to prevent heat means your plant won’t receive enough light for its growing needs.

2.    Regular Halogen Bulb

The regular halogen bulbs are of a close match with the incandescent bulb. However, they differ in the passage of their electrical current which is passed through a tungsten filament.

They work by emitting more heat for lesser energy. However, they can’t produce efficient light for plants’ growth. They would have required about 29 watts (less than 11 of an incandescent bulb) to be more efficient for plants growing needs.

3.    Regular Fluorescence Light Bulb For Plants

Fluorescent light works with the passage of electricity along with mercury particles and is filtered by an outer bulb coating.

The fluorescent light is one of the most appropriate regular lights that can be used to grow plants. They are affordable and more efficient. Unlike incandescent light, they do not consume too much power. Thus they will reduce your cost. The heat they produce is also moderate for your plant’s growth.

The regular fluorescent light bulb is found in most homes and they will offer your plants the required light. All you need do is ensure the color temperature of the bulb is ideal for your plants’ growth. This is because plants require various color temperatures (measured in Kelvin) for various plant stages.

However, to save yourself the stress of determining color temperatures, you can simply go for a specialized fluorescent bulb made for plant growing needs. This type of fluorescent bulb contains the required color temperatures your plants will need for their growth life cycle.

Also, your regular fluorescent light bulbs are great for germinating seedlings. With fluorescent light bulbs, there’s no need for investing in extra grow light fixtures for your growing seedlings. Your growing seedlings require about 16 to 18 hours of light daily.


Can plants photosynthesize with normal light bulbs?

The answer is yes. There are many examples of photosynthetic organisms, including plants, that can use normal incandescent light bulbs and grow just fine. The main reason why these organisms can do so is because they have evolved to be able to use the spectrum of light that the bulb emits. Some organisms can even absorb some light from the bulbs. However, most organisms cannot use the light from the bulb, and must instead absorb the energy from sunlight.

Is it important to choose the right light?

Yes! There are many different types of grow lights available. They are designed for specific purposes, such as growing flowering plants, or producing vegetables, and can come in various shapes and sizes. Some grow lights are designed to be mounted directly onto the sides of a house or greenhouse, and they can be installed either inside or outside. Some are designed to fit inside the ceiling of a building, and are often known as “under-ceiling” lights.

You can also find grow lights that you hang from the ceiling, or that you hang on the side of your house. Some grow lights have a single light bulb, while others have multiple bulbs. The size of the grow light will determine how much light is needed to grow a plant.

What is the difference between a grow light and a regular light bulb?

Light bulbs are used to illuminate areas of the home, office or garden. Grow lights are used to light up plants. Grow lights are available in both incandescent and LED varieties. These lights are generally available in either grow light kits or grow lights. A grow light kit contains all the equipment needed to start a plant, while a grow light is an additional piece of equipment that helps with the growth of your plant.

The use of grow lights has grown tremendously over the past decade. They are often used as supplemental lighting for indoor gardening. While grow lights can be used for any type of plant, they are especially useful for plants that grow in soil. Grow lights come in many shapes and sizes, so it is important to know which size you will need before purchasing. The shape of the grow light also affects how it will perform. Some grow lights have multiple lights, while others have just one or two. The number of lights also varies. Some grow lights have a built-in reflector, while others are without one. The reflector is needed to direct the light where it is needed. The purpose of a grow light is to provide light for your plant. When choosing a grow light, it is important to consider the type of plant you will be growing. You can choose between LED or incandescent.

Final Will A Regular Light Bulb Grow Plants?

We can now see that a regular light bulb may help plants grow depending on the type used. Also, ensure you take note of your plants’ progress whenever you make use of these regular lights. The signs they indicate will tell you if you need to replace them or add a stronger grow light.
