In general, sunlight is better for plant growth as it is intense and contains the full spectrum of electromagnetic radiation required for optimal plant growth.

Artificial light, if it is an ordinary room light, will only support low-light tolerant plants. Most artificial light sources (fluorescent and incandescent) do not provide the full visible light spectrum that is required by plants for optimal growth, this results in plants that are tall and spindly (etiolated) and sometimes discolored.

However, there are special lights with a spectrum that is tailored for growing plants. They have to be on for longer hours than sunlight, but as long as a plant is getting enough light-energy to manufacture its food, it will grow well. It doesn't matter whether that light is coming from the sun or from grow lights.

The downside to extended exposure to light is the plants metabolic functions operate twice as hard for the same amount of output. Recent studies have also highlighted some of the negative aspects of extended photosynthetic periods (extended light reactive period and shortened dark reaction period).

There are times when artificial light has an advantage.

Hydroponic gardening with artificial light makes it possible to grow plants in unreliable climates that are lacking in sunshine - think of the long "night" periods of areas of the northern hemisphere. In some places in Canada forage for animals is produced indoors during the winter months in artificial conditions.

Supplemental lighting is used in horticulture to produce plants in flower outside of their normal flowering period. For instance Christmas cactus, poinsettias, tulips, narcissus, chrysanthemums, etc.

Many houseplants grow better under artificial lamps, not because of the lights, but because it keeps them away from drafty windowsills!


Plants will grow better under sunlight; artificial light lacks the complete spectrum of light provided by the sun. You can purchase "grow lights" which have a special coating on the bulb to produce more light in the spectrum that plants need to photosynthesize. However, they can never completely duplicate natural sunlight.
Artificial lights are produced to help humans see in the dark, so they only need to produce light in the visible spectrum.

What types of plants grow better in artificial light a nasturtium or a sunflower?

Both of these flowers require full sunlight to bloom, something which artificial lighting just cannot duplicate without considerable expense (a high-intensity UV growing setup might do the trick). That's not to mention the space required: sunflowers can grow up to 12 feet in height, and even dwarf ( Full Answer )

Will a plant grow in artificial light?

Growing plants with artificial light is very popular. Growingplants with artificial light is particularly useful when naturallight is not abundant.

Can a plant grow in artificial light?

Plants are grown in artificial light all the time. As long as the photons of light are of the correct wavelength the plant does not care where the light comes from.

What type of light do plants grow better in a grow light a regular light bulb a blacklight or sunlight Why?

Sunlight. Light is measured in Lumens, the Sun emits anywhere from 32,000 and 100,000 lumens per square meter (depending on the location). A typical grow light (High Pressure Sodium / Metal Halide) produces around 50,000 lumens per square foot. In peak conditions, the Sun can double the lumens of ( Full Answer )

Can you grow plants in artificial light?

You can grow plants in artificial light. This is through theprocess known as hydroponics which can use incandescent, florescentor LED bulbs within an enclosed environment.

Why do plants grow better under certain wavelengths of light?

because some wavelengths are more simliar to the ones the sun emits and natural light is best for growing plants in which case the more similar they are to the sun's wavelengths they are, the better it is for the plants.

How do plants grow under artificial light?

Gravitropism's plant response to gravity, phototropism to light. Plant organs such as root and stem tips, and light-sensitive receptors, sense the different wavelengths of blue light and of red. Below ground, gravity and negative sensitivity to blue draw plant roots downward. Above ground, light sen ( Full Answer )

Why is sunlight better than artificial light?

Sunlight has all the natural spectra of light from red to violet in a proportionate way in artificial light some wavelengths are meagre or even missing.

Can plants grow with artificial light?

Plants are grown in artificial light all the time. As long as the photons of light are of the correct wavelength the plant does not care where the light comes from.

Do plants grow better in direct sunlight?

yes because they use the sunlight to create photosynthesis which is where their leaves take in sunlight for the key nutrients they need

Can you grow a plant using artificial light?

Yes it is possible to grow plants using artificial light as long as the frequencies and quality of light supplied is acceptable. An extreme example of this practice is where Marijuana plants are grown indoors in an artificial environment so that they are not detected by authorities

Why don't plants grow better in artificial light?

The reason why plants do not grow between in artificial light isbecause the energy that is transmitted to the plants is not asstrong as that which comes from the sun. Natural sunlight is alsomore equally distributed to plants than artificial light would be.

What plants grow better in direct sunlight?

The amount of solar radiation is highly variable depending on altitude and geographical location. You will need to provide the above information with your question since direct sunlight is not same everywhere. http://i31.tinypic.comiw5frn.jpg
