I just remembered where I read that: Molecular Mechanisms of Photosynthesis (ISBN 9780632043217), page 182. "...the rate of carboxylation is only about three times the rate of oxygenation under normal physiological conditions."
thepaan Reviewed by thepaan 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
