What Spectrum Of Light Is Required For Plant Growth

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.

What spectrum of light is required for plant growth.

Led grow light 12 to 24 inches. Other lights such as leds or fluorescents may emit light from a number of narrow wavelengths with gaps or peaks within the spectrum. 24 to 60 inches. We ll also look at three different plant pigments that capture some of this light.

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. Outdoor conditions are mimicked with varying colour temperatures and spectral outputs from the grow light as well as varying the intensity of the lamps depending on the type of plant being cultivated the stage of. Light is vital to a plant s growth and survival. Chlorophyll in the plant foliage absorbs light to provide energy for all of the plant s.

That s where the solarsystem controller comes in. In this article we will go a little beyond the visible light spectrum and look at the 100 750 nm range. 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. 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.

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. 3 to 12 inches. Using the best uv led lights for plants isn t enough. 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.

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. Obtain full grow light spectrum control and more. The growth characteristics examined included leaf area chlorophyll levels petiole length leaf stem length stem length and dry yield. Lec lights provide the full 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. Here are the basic parameters.
