Light is essential for plant growth and development, and plants need light for photosynthesis. The photosynthesis of plants can be carried out smoothly, and there are many factors, the main factors are light quality, light intensity and photoperiod.
First, the quality of light
Different light has different effects on plants. After continuous research, it is found that red light and blue light have the greatest influence on plant growth. Different plants need different light ratios at different growth stages.
Second, the light intensity
Within a certain range of light intensity, the photosynthetic rate of the plant increases with the increase of the illuminance. When the illuminance rises to a certain value, the photosynthetic rate does not continue to increase the illuminance value, which is the so-called light saturation point.
Third, the photoperiod
The photoperiod refers to the alternating change of the illumination period and the duration of the dark period in the day and night cycle. Different plants have different photoperiods at different stages of growth.
In summary, under the same conditions, the stronger the light, the better, but after reaching the light saturation point, the light intensity can not have more effects. The power of LED plant lights is an important factor affecting light intensity. From this point of view, the power of the LED plant lamp is not as large as possible.
