hello torog mate,
i think latewood mentioned about the possabillity of growing weed from start to finish on a 12/12 cycle, i am pretty sure that this can be done with ruderrauls skunk, not sure how its spelt lol, but i know this grows freely in russia and has addapted its self to reproducing it self at this or very close to this cycle, i also no that breeders have been inbreeding this into some of there strains as a way to speed up there stock. as a plant i dont think its up to much for smoking but as fast plant its realy cool, i believe around 50/% will finish around the 12 hour of light cycle.
peace happy .................. ps

i once grew leda uno, i believe this had that strain inbred into it, as half my crop finished very very early, around the end of august. the rest come through around end of sept ...................................
