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.
RackitMan Reviewed by RackitMan on . 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
