How long will it take a pant to flower if you put it on 12/12 from day one? About a month in a half or two months?

that sounds about right..

All that i state is a lie.

You shouldnt start off a seedling at 12/12.. it has to go thru vegitative growth, to get healthy and strong. unless you have an auto-flowering plant like lowryder, which has light 24 hrs a day. I mean I force-flower myself but I give it atleast like 20 days, if not longer, of 24hrs light.
