i have grown plants 12/12 from seed with no veg cycle with great results. they dont "need" a veg cycle. and as far as the author claiming his technique is a result of extensive experimentation is fine and dandy, but until i see a grow with pics i'm not gonna try it. would you? If somebody claimed they did a bunch of experiments and the results said it was good to water my plants with vodka and orange juice i'm not gonna try it, i'm gonna think its absurd. show me a grow with increase yields from it and me and the ladies will be getting hammered on screwdrivers! and im not saying you are absurd, but that idea in that link seems to be. all i'm saying is it doesnt make sense... the only places on earth that ever gets 21 hours of light is the north and south poles, and nothing grows there. The equator gets 12/12 and thats where the lushest vegetation on the planet is. try it, if it works out and you get an improved yeild i'm on board. until then, it seems absurd. the earth is still flat, right???
