Can you grow plants in artificial light?
You can grow plants in artificial light. This is through the process known as hydroponics which can use incandescent, florescent or LED bulbs within an enclosed environment.
Under artificial light, plants are not subject to weather conditions, insects, parasitic and aggressive plants. Also the light is more consistent and can be provided for more hours. So the consensus must be that plants will grow better under artificial light rather than natural light unless their species is particularly sensitive to the wave length of the light.
Artificial light is usually sufficient for most plants as long as it is on for a good length of time. It is important to understand that flowering plants NEED a dark period, this is sometimes a problem if artificial lights are left on overnight for long periods of time. Natural light is much better as it stimulates more growth but you can get artificial lights that are nearly as good as the sun. Occasionally, a…
How plant growth is affected by artificial light depends on the type of light that is being discussed. While all plants grow best in natural light, plants can an do grow and thrive under artificial lighting conditions. Overall, the best lighting choice should give off a high amount of blue, red and yellow light. Plants need the light in the blue spectrum to provide energy for photosynthesis. Light in the red spectrum encourages blooming, and…
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…
Generally, yes. Artificial light struggles to be as strong as sunlight, so plants have less energy available to them. I've worked in a professional indoor plant growth chamber, and the light level was only 1/3 as strong as direct sunlight. However, some artificial grow lights use the specific wavelengths that plants use, so there is the potential for artificial light to be more efficient.
Plants have evolved to use the light of the Sun as a source of energy, they will do better in natural sunlight than artificial light. Also sunlight causes no pollution as plats use it, while artificial light usually involves burning of fossil fuels to make and therefore using artificial lights to grow plants that can perfectly well use Sunlight is bad for the planet.
Without a doubt, sunlight. While artificial light can provide the basic light that plants need, there is still no way to match the color spectrum and intensity that the sun creates. That being said, I grow plants using grow lights in winter or if they have light requirements that aren't fulfilled by my windows.
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.
