Designing my foot locker grow box
Thats strange and wrong.It's strange, I looked up the kelvin light spectrum and it says Flourescent Cool Whites are 4500k... but GE's website says they are 2700k. I suppose I should believe the GE page.
2 700K is warm, cool white is around 4 000, and 6 000 is blue. Any source will tell you that.
Theres no controvesry there, its common knowledge in these circles.
