Best Light Wavelength for Plant Growth
Best Light Wavelength for Plant Growth. You can boost the size of your plants by giving them the most sunlight for the longest possible time. Quite often, plants can naturally grow to optimal size, but certain products are proven to emanate the best light wavelength for plant growth.
You can boost the size of your plants by giving them the most sunlight for the longest possible time. Quite often, plants can naturally grow to optimal size, but certain products are proven to emanate the best light wavelength for plant growth.
Types
The best type of light wavelength for plant growth falls anywhere in the blue and red part of the visible light spectrum, reports Oregon State's botany website. According to Maricopa Community College, blue and red wavelengths are around 400 nanometers to 700 nanometers in length.
Misconceptions
Although we often associate the color green with plant life, green wavelengths (500 to 525 nanometers) are actually useless for plant growth. Objects reflect colors that they do not absorb, reports Oregon State.
Considerations
Natural sunlight contains enough blue and red light to promote growth in plants, according to Oregon State. Sunlight also costs nothing and does not pollute the air.
Prevention/Solution
You can promote further plant growth by increasing the exposure and duration of sunlight to plants. Mirrors pointed at your plants can increase exposure to light very cheaply. Make sure to remove anything that provides shade, such as overhanging plants.
Expert Insight
For indoor plants, fluorescent lighting provides a close imitation to the red and blue light from the sun, reports Oregon State. Incandescent lights are less effective because they contain lots of red and orange, but generate too much heat.
