Micromoles are like tomatoes. It was a joke but … let’s continue. In fact, tomatoes all look the same but when you taste them you understand the differences.
Even the micromoles are not all the same; if you use 90-95% of red LEDs you will have many micromoles but the plant (in this case the tomato plant) also needs white light, in practice it grows better and produces more with a full color spectrum!
The full spectrum is also essential for greenhouse work; the very low color rendering of a red-blue spectrum affects (severely) the health and performance of workers. Everything can be solved with a pleasantly white light (albeit with red components), similar to that of the sun!
