I think it would be ok to test with the light in one system on its performance. But maybe just test with one system so we can compare... Or take one level of every tower.
Maybe all the top levels?
Carlos my colleague emailed with Someone from WUR (a senior scientist at the WUR department glastuinbouw) about the LED lights we use and weather our color ratio is ok. He basically says: without daylight, use 15% blue light and the rest red. If you also have daylight 5% blue light would be enough. He says % blue light and not % blue LEDs there is a difference of course
