Here it is: and here ladies and gentlemen is the reason for using 18/6 as opposed to 24/0 and why 12/12 stimulates flowering. if you understood all of this so far, then it is safe to assume that you know about day and night and circadian rhythms and the bodies biological clock, well. plants have them too. there is such thing as a time keeping protein and repressor proteins. in plants this protein is sensitive to light on the 24 hour cycle of light to dark, this protein in plants is called TOC, here is the latest information on it. at dawn repressor genes are activated by light witch over the course of the day slows the production of TOC and therefore decreases concentration, at night when there is no light to produce repressors, TOC levels rise and are circulated through the plant, especially near meristematic tissue where ALL plant growht occurs. it is this oscillation of TOC and repressors over the 18/6 cycle that keep hormones in regulation for vegetative growth. during the 12/12 cycle- TOC and its repressors are at a certain chemical equilibrium(keep in mind the concentration and therefore times in cycle are different for all plants, cannabis seems to like 12/12 for its hormone equilibrium for flowering) anyways 12/12 TOC levels stimulate the production of flowering hormones- confused yet, hormones are coming up. just like an athlete using steroids, never using your god given testosterone means you'll have stunted testosterone production when you kick the steroids. same in plants, if you leave it on 24/0 cycle, youll never achieve the proper hormone regulation for flowering, well you will get better vegetative growth,and buds too, just not nearly as potent as if you had done it the way natures intends, so remember, light and dark, cycles of TOC regulate expression of hormones, mainly gibberellins and ethylene. Biology lesson.
