The wavelength of light, and does not count the light intensity

First, I have to clean up a misconception, as many reviews refer to it and provide both a false picture of the product as well as the proper plant care. A plant the LUMEN (light intensity) almost does not matter !!! It is important to the proper wavelength of light. Not for nothing plants are green and not purple or red because they absorb a certain light spectrum need speak. This is green plant ziwschen 500 and 700nm. Substituting the LUMEN with the same wavelength of light that would be about as as one would equate amps and volts.

An example, there are LED lamps, which produce up to 20.000LUMEN. Under warranty but would any plant that is illuminated so enter, because the light spectrum of an LED lamp is very limited, even if the light intensity is enormous. With the Bio Green LUM 151 could be (depending of course on other factors) theoretically high breed the plants in the basement as well as outside in the summer.

I personal use plant light for my bonsai pupils (mostly tropical or sub-tropical tree species), where the necessary sun lacking in the winter months. Only the size of the lamp limits their Wikrung. So for more than 2-3 plants you should purchase and 2-3 lamps.

Price / money accommodation right in so far as well as the included special energy-saving lamp in the retail sometimes can cost loosely over 10euro. From me, saying a strong buy recommendation !!!
