It surely has alot to do with your grow method, personally I will be topping and screening, and then flowering at 1', this will give me about 8 7" cola's per plant (or so I hope). I'm only looking for big colas for personal use, I plan on giving all the undergrowth away, so I guess, really... whatever your looking for. I want more big firm colas, less popcorn, and I'll be flowering right away -

Keep in mind, I'm on my first grow, and a novice when it comes to cannabis, but I've grown plenty of fruits and veggies, a 'weed' should be pretty simple

So if it were me, and my plants where 12", I'd be flowering, but my setup might not be like yours. My question is, why are you transplanting now? From what I've read you should have transplanted around 4-5", about when the roots were filling up the bottom of your seedlings pot. Again, my grow is a little different, but I'll be putting my seedlings directly into what I plan to flower in - Not sure exactly what that is yet, you can read my grow log if you want (not thread jacking)

Best of luck to you, have you topped or fim'ed at all?
No topping yet. Maybe I should since I have limited space in my tent. I had no choice on the clones as I committed to buy them and found they were way too big for the pot they were in so as soon as I got them I had to transplant. Some of my other containers I got I just decided they were too small once they started slowing growing a little. Half of my plants were put right from their sprouted seed into the pot they will finish in so thankfully I wont have to transplant those. Pictures to follow
