yo RS420, i think the experienced veterans are trying to tell ya to keep vegn' til they're at least a foot tall dude. if you start 12/12 now you'll have like really bogus buddage that's not real potent, ya know dude? get a couple books from fsbook company or someone like that and you'll see all the different ways to grow. there's hundreds of ways to grow, but if you flower now, you're buds won't be real dense or potent, unless you're growing Lowryder, those are like a foot tall in the end and only take 8 weeks from seed to bud, and from what I hear are fairly potent indica variety. But if you have sativas, the longer you veg, it gives the plant more time to produce more THC when you go to 12/12 to flower, and the flowering will produce even more THC, if you do it for at least 8 to 10 weeks. get High Times Magazine at Borders, there's all kinds of stories and advice in there too, besides companies that sell books and equipment. Good Luck Man!
