Inducing Flowering Inside then Moving Plants Outside in June??? Will they just Reveg?

Hey folks- I had this question over in General Growing for a few days but haven't had any responses so I figured I'd try here:

I live in an area where the killing frost date is typically late September. The equinox (12/12 light dark outdoors) is Sept 21. I am concerned that any outdoor plants will not even start flowering until it is way too late in my climate. Can I induce seedlings to flower by keeping them at 12/12 indoors until flowering is well underway, and then transplant these outside in full summer and expect flowering to continue, or will they just reveg or become hermies? Thanks for any insights. Cheers​

I would think July, right after the summer solstice. I find that plants behave one way when the light increases by the day and another when light is decreaseing by the day !!

I've been able to induce flowering with 13 hours of light, for what it's worth. So I'm guessing if you do what you propose it could work, but I'd definitely have them flowering at least a couple weeks before I put them outside. Is this a guerrilla grow? Otherwise you could consider a little shelter or clear plastic bag to protect them from frost before winter really sets in. Might get a few extra weeks that way.

I live in SoCal where most of my neighbors don't even know what snow looks like, so I've often wondered what would happen if I planted some bagseed outside in late summer/early fall or even late fall/early winter. It seems like that would be a good way of getting buds in a hurry without having big high-visibility plants out where cops or crooks can see them. Of course, the product you harvest could be shit or gold and it would be hard to predict which way it would fall.

My indoor/sunlight plant went to flower with 14 hours of light, 10 hours of dark....I would bring it into a dark room at 9pm and return to light at 7am (I know this is not ideal, but it fit into my personal schedule).

I've forced flowered outdoors early in the season. Not sure how big your plants are, but I made a 4ftx4ftx5ft rectangular tent using black and white plastic (panda sheeting). Approximately 12hrs after sunrise I would put the plant in the tent and take in out later at night a couple hours later. I wasn't always able to get them in the tent on time, so some days (less than 10% of flowering days) they would get 1/2 to 1hr or so of extra sunlight. I used this method twice successfully without any hermaphroditic tendencies or re-vegging.

Have you ever tried autoflower strains? They take less than 3 months start to finish regardless of light cycle I think. Ive never used them but I know people with short growing seasons like yourself use them successfully. You could maybe pull off a short flowering indica of a regular photoperiod strain,the plant will start flowering before sept 21.Outside they dont wait until 12 hours of darkness,they can tell when they days are getting shorter and start budding around august usually.

Is this a harvest picture?
not quite, harvest was about 3 weeks after, but the size didn't get much bigger, the buds just firmed up and trichromes turned milkly.

I know it's small, but it was grown with limited sunlight (under 6hrs/day), plain potting soil, tap water and no nutes....yeilded 18 grams of very decent bud.

few extra pics of some younger days, sorry lost all the final pics of her
