I know people that had some nearly full 100% satvias that took 4-5 weeks on 12/12 before flowering. It was an unknown freebie give-away from seedbay called 007 and it got to about 5-6 tall w/o starting to flower and he had to cut it down for some reason most likely because of room size. But normally I go a month and than into 12/12 but I stick to mainly Indica sided strains.
