| LED - Trying to unravel the mystery.
Plants actually use red and blue light to photosynthesize. The rest of the light spectrum is not used in a significant amount. This is why LED panels for plants will be a mix of red and blue lights. This is usually at a 75% Red to 25% Blue ratio.
LED's panels will not seem to appear as bright as a high wattage white light because they are not using the whole spectrum.
I have a several 272 bulb panels over my orchids. Each panel is 14W and is said to provide the light intensity of a 250 Metal Halide bulb. Each 14W panel covers approximately one square foot.
I have had a couple of these for several months and have had good results. So far I like them. |
