How to choose plant grow lights?

1.LED grow lights The LED is relatively power-saving, emits little waste heat, and has a long life. LED planting is absolutely possible, I recommend quantum board for home planting. The LED can be full spectrum, and the lamp beads are evenly distributed, which can illuminate a small area at close range. For small plants, the balanced spectral distribution is very suitable for growth, and now there are LEDs with medium-wave ultraviolet rays. LEDs are more energy-efficient, and the lamp beads are evenly distributed and can be planted with large-scale plants. In general, full-spectrum LEDs are more suitable for greenhouse and factory planting. If you add UVB lamp beads alone, large area and high intensity, it is possible. If annual plants do not consider root development and morphology, red and blue are sufficient. If you consider root development, orange light needs to be added. Orange light also has a certain underground accumulation effect.

Three primary colors

The heat is not too much, it is cheap, the spectral distribution is not very reasonable, the energy consumption is relatively large, and the utilization rate of the light emitted by plants is below 70%. The disadvantage of using three primary colors is that the energy consumption is still a bit large, and no light intensity of 10000LX can be said to be ineffective for desert plants. But the energy required for 10000LX is quite terrifying. I have calculated that it is more than 500 watts per square meter (50CM distance), which is not economical for long-term use.

Little Sun

As the name suggests, it is a small sun, which fully mimics the sun's illumination and even generates heat. If enough, bright enough, the same effect as sunlight. But if the condition is "enough", the energy consumption is terrible, and the South African plants we like don't like to be too hot. This is absolutely useless. It has a good effect on growing tropical aquatic plants, or if you plan to plant lotus flowers off-season, it’s okay, but the energy consumption is too alarming, so it is abandoned.

Rare earth lamp

The main ingredient is copper-selenium powder, which creates a specific spectrum, and there are two kinds of blue and pink. The same is true for aquarium lamps, which are fluorescent lamps like the three primary colors. The spectral accuracy is higher than that of the three primary colors and less than that of the LED, which means that the energy consumption is higher than that of the LED to achieve the same effect, and the life span is shorter than that of the LED.
