Difference between indoor and outdoor flower time?

If a plant takes 10 weeks to flower indoors, how much longer will it take outdoors. I have some outdoor plants in containers that are 2 weeks into flower. I'm at the same latitude as Phoenix, AZ-32 degrees north? Just wonder how much longer I'm looking at 2 weeks? 4 weeks?

BTW, these are a bunch of fems from Sannies. They look great, but I've never smoked any of these

There is no difference from what I hear

a photo period for a plant is the same in both in and outdoor...you just dont see it like that because your not the one controlling when they switch over...

There is no difference otherwise seed companies would market them with indoor and outdoor flowering times. The only difference you'll have is the amount of veg time you had given them prior to flowering as well as sunlight compared to artificial light. But thats going off topic.
