Is it better to use full-spectrum or red and blue light for plant lights?

Grow lights can replace sunlight to supplement light and promote plant growth. It can be used when growing vegetables, fruits, and flowers. It can not only promote the growth of seedlings, but also promote flowering and fruiting, increase production, and market in advance. There are many types, and the spectrum has full spectrum and red and blue light spectrum. Is the full spectrum better or the red and blue light spectrum?

After studying the absorption and utilization of sunlight by plant growth, people have found that the absorption and utilization of red and blue light in sunlight is the largest by plants. Red light can promote plant flowering and fruit, and blue light can promote plant growth, stems and leaves. So in the later research on plant lights, people developed plant lights with red and blue spectrum. This kind of lamp has the best effect on supplementing light for the growth of plants, and it has better effect on crops and flowers that need to ensure the color. Moreover, the red and blue light can be matched according to requirements to obtain the most suitable spectrum for plant growth.

Red and blue plant lights have only two spectra of red and blue light, while full-spectrum plant lights simulate sunlight. The spectrum is the same as sunlight, and the light emitted is white light. Both have the effect of supplementing light and promoting 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 plant lights, which can color, promote flowering and fruiting, and increase yield. For leafy crops, full-spectrum plant lights can be used. If you grow plants at home, it is best to choose a full-spectrum plant light, because the light of the red and blue plant light is pink, if people stay in this environment for a long time, they will feel dizzy, nauseous, and unwell.
