That is also quite dependant on where the fellow lives. All you need to look at is how long daylight hours are at this particular time of year in your particular area. I highly doubt you are getting twelve hours of night and twelve hours of daylight, or something close. But if you are (say 11/13, 12.5/11.5 etc), you might be alright until summer kicks in and daylight hours become ever longer. We get around 14-15 hours a day already where I live, so if I were to move my girls outside now they'd probably kick right back into vegitation.
The bottom line is that the photoperiod
will determine what your plant thinks it has to do, regardless of its stage of life.
My best suggestion is harvest as soon as your girl is ready and if it's still high summer stick her outside after harvest (look up
re-vegging, the plant has to be harvested without killing the plant). Let her revegitate and harvest her a second time or use her for clones!
