It is best to remove the meat to absorb the sun's rays. This saves money and electricity, and it can also burn the body.
There is not enough light, so we can only use light to compensate. Full spectrum UVB metal halide solar lamp, with UVB and sufficient illumination. Practice has proven that the effect can be observed in 5 days for 8 hours a day.
If you don't have time, you can only use full-spectrum metal halide solar lamps (animal time), which are the lamps closest to the solar spectrum. But pay attention to the distance. The UVB of this lamp is very strong. Long-term and too strong ultraviolet rays will damage the surface of succulent plants. So it is recommended to irradiate the succulent plant fill light at a distance of 60-80cm. It's a safe distance. UVB ist at the same level as the ultraviolet rays of the morning sun outside. 6 to 8 hours a day is more than enough. The recommended distance for 35W is 60cm, and the recommended distance for 70W is 80cm, and the light intensity both can reach 10,000.
It is a misunderstanding that the LED plant lighting used in greenhouses is used as succulent filler. light. This type is made of red and blue lamp beads, which has an obvious effect on promoting photosynthesis of green plants. The problem is that our succulents look best when they are small and sturdy, not when they are tall and thin. This is the problem of excessive length. Since there is no UVB in this type of LED light, it cannot limit excessive growth of succulent plants. This can only reinforce the problem of excessive growth.
I am a lamp maker. I don't believe that an LEDcan have all bands, from UVB to visible light. First of all, UVB, UVA and visible light lamp beads have different voltages and currents, and cannot be powered by a single power supply. Secondly, the cost of UVB lamp beads for 0.01W exceeds 70 yuan, but the service life does not exceed 200 hours. It cannot be put into practice at all.
There are also major brands of metal halide lamps such as Philips and Osram that do not contain ultraviolet rays. If you think about those shopping mall spotlights with ultraviolet rays, clothes and furniture would have faded a long time ago. Many people have been deceived.
