What Spectrum Of Light Is Required For Plant Growth

Light intensity was maintained at the same level in each growth chamber so that the effect of each light spectrum on plant growth could be compared precisely.

What spectrum of light is required for plant growth. Led and t5 fluorescent lights can either be blue or red or can have a blended spectrum. As different plants use different parts of the light spectrum at different stages even the best light for growing plants indoors requires a versatile control system. The best plant light spectrum for growing flowering plants. In this article we will go a little beyond the visible light spectrum and look at the 100 750 nm range.

As the plants grow raise the light fixture accordingly to maintain the optimal distance which varies depending on the type of bulb used and its wattage the higher the wattage the farther away the bulb can be. The growth characteristics examined included leaf area chlorophyll levels petiole length leaf stem length stem length and dry yield. 3 to 12 inches. Obtain full grow light spectrum control and more.

Lec lights provide the full spectrum. In other words even if the light appears the same to the eye it may be missing certain wavelengths colours that plants require for healthy growth. Here are the basic parameters. Light that mimics sunlight s full range of warm and cool colors from red to blue is best for growing plants blue is for vegetative growth the red spectrum is for flowers thompson explains.

Grow lights either attempt to provide a light spectrum similar to that of the sun or to provide a spectrum that is more tailored to the needs of the plants being cultivated. 24 to 60 inches. Light is vital to a plant s growth and survival. By breaking down the light spectrum into bands determined by the wavelength we can examine more closely how each band of light affects plant growth.

Other lights such as leds or fluorescents may emit light from a number of narrow wavelengths with gaps or peaks within the spectrum. Many led grow light suppliers have conflicting information on the topic due to bad marketing or simply a lack of knowledge in plant and light research. That s where the solarsystem controller comes in. Led grow light 12 to 24 inches.

Chlorophyll in the plant foliage absorbs light to provide energy for all of the plant s. We ll also look at three different plant pigments that capture some of this light.
