Importance of 460nm red LEDs?

[stra8outtaWeed]

Hey Str8,

While I am ultimately interested in results and would like to read more about your grows; as an engineer, I need to know more about the science behind a particular design and the science as currently presented does not jive.

i'm not an engineer but my results are real world...that is what is important to me:thumbsup:

the one thing i have learned is 660nm is important in getting a good flower run and they are the most expensive diode so many makes of LED lights just selling price alone do not have good 660nm diodes.:hippy:

so the cheap ones are really only good to grow in veg with...this is like comparing CFL to HID:smokin:

stra8outtaWeed Reviewed by stra8outtaWeed on 03-29-2010. Importance of 460nm red LEDs? Here is something very confusing to me. Many LED proponents loudly proclaim the need for 460-470nm red LEDs over the cheaper 630nm LEDs. I understand that this better coincides with the accepted chlorophyll B absorption peak. So far so good. LEDs veg very well given appropriate wattage & color. So far so good. LEDs do not compare (generally) to HPS flowering as far as yield. (Please - let's not go off in that direction here. Thank you!) Rating: 5
