Hey I like your video on youtube stealth Grow LED facts part 2 where you claim green and yellow light is not really absorbed or used by plants , which is false . The graph you are showing is of chlorophyll and pigments dissolved in an alcohol solution , not in vivo . Green is more photosynthetically efficient than redhtml . If you wanna compare lumens instead of PAR or PPF , then a top bin CXB 3590 can achieve 162 lmw . <| sep |> I am a first generation American but I have a lot of family from USSR who were party members . They are all antigay , antitrans , and find the new youth movement to be degenerate the New Left , SJW crowd . Lenin legalized homosexuality , but Stalin repelled those laws , and where generally pretty conservative then it came to social issues . So you can blame Stalin for your families opinion .
