I came across this article while looking for some information on lumens and learned a few new things. Maybe some of you old fogies can learn something too from it! Enjoy.

Yeah I was curious to see what they were exactly. I also was attempting to give an accurate quote of the lumens my growspace emitted but noticed there are 2 types of lumens; brightness and photopic. Perhaps you can shed some light on which one you should classify lumens in with regards to plant growth. I think it is brightness, because photopic relates to the way the human eye perceives light?

Yeah I decided to break away from the norm and judge my colors in wavelength (nanometers) which is convertible to match the PAR spectrum. And I figure the sun wont lie to me
