Plant grow lights LED are used to supplement light for plants in places where there is a lack of light and reduce the photosynthesis of plants that are affected by weather, resulting in plant diseases in the growing environment. But for most growers, plant growth lights have a variety of spectrums. Is it better to choose full-spectrum LED grow lights or red and blue LED grow lights?
Knowledge of red and blue plant grow lights & full-spectrum LED grow lights
First of all, we need to know that red light can promote plant flowering and fruiting, and blue light can promote plant growth of stems and leaves. This is a band range that is targeted for research based on the impact of the spectrum of sunlight on plants. LED light lamp beads mainly include red light beads, blue light beads, and full-spectrum light beads.
The main role of red light on plants is to adjust the photoperiod of plants and affect the flowering and results of plants. The main role of blue light is to affect the movement of leaves and plastids, promote the growth of stems and leaves, and inhibit the flowering and fruiting of plants to a certain extent.
Selection of spectrum
There are only two spectrums of red light and blue light in the red and blue LED grow light, while the full spectrum LED grow lights simulate sunlight, and the spectrum is the same as that of sunlight, and the light emitted is white light. Both of them have the effect of supplementing light to promote plant growth, but different crops should pay attention to choosing the most suitable one when choosing the spectrum.
For flowering and fruiting, crops and flowers that need to be colored, it is best to use red and blue LED grow light, which can color, promote flowering, and increase yield. For leafy crops, full-spectrum LED grow lights can be used. Then if you grow plants at home, it is best to choose a full-spectrum plant light, because the red and blue LED light lamp is pink.
Whether to choose a full-spectrum plant light or a red-blue ratio plant light depends on the plant’s spectral requirements, light efficiency, power, growth stage and cycle, and other factors to decide. It is most important to find a formula solution suitable for plants.
