led grow light

Different plants have different requirements for spectra, such as lettuce is red/blue 4:1, strawberry 5:1, universal 8:1, some need to increase infrared and ultraviolet rays, but some factories know little about all the spectra and make it known as the full spectrum for any plant, as a result, because it contains ultraviolet rays to illuminate people's orchids, not hundreds of thousands of that kind. White light contains all the spectra, so someone else has a white LED, which is full spectrum, and Philips has done this foolish thing. And I did an experiment, the same plant, while using two 200 W white light, while using a 90 w UFO (red and blue 1:1) and 90 w square (red and blue 8:1). A week later, the plants under white light are obviously slower than those under red and blue light. Don't be superstitious about white light. At most, add a few white LEDs to the red and blue light to improve the use, rather than as the main light. The output lumen of the LED itself is not high, some customers say Philips is useless, because Philips these T-tube lamps maximum is 20w, also added a grinding lampshade, and lost part of the lumen. How many micromoles are left when you hang high and shoot on plants? The effect is strange. The LED plant lamp below 50 W is suitable for use near plants, which is more suitable for plant tissue culture (layered planting), family flower and vegetable cultivation, small space soilless cultivation and other fields, while the LED plant lamp above 50 W is suitable for greenhouse greenhouse use, and the distance between the lamp and the main crown area of crops is better controlled within 2.5 meters.
