You're most welcome, and to clarify my own position, I am + towards either/both kinds of use. I started out smoking because I *really* like getting high, not because I thought there was some medical value in it. 43 years now all told.
Whether or not they reveg will really depend on how they've been being grown while inside. If they've been put on a strict light schedule, then in my experience a difference of as little as 1hr reduced daylight will cause them to start flowering. I do know a nursery provider here in California who has a computer program that matches the clones to actual daylight phase (at a particular latitude I'm assuming) and those cuts grew out just like seed starts. But that's the only time I've had that experience, otherwise I have always had to add at least a small amount of light.
My last outdoor grow (keep in mind this was in the central Sierra Nevada, not sure how much farther north than you we're talking, but for sure farther north) I slapped like.. I dunno, 3-5 of those cheap solar walkway lights in the greenhouse and that kept everything from flipping on me. If it's possible for you to do the same thing, then great. OTHERWISE, you might want to learn about how light deprivation works, because once they flip into flower, as I think you now know, it's really better to keep them flowering. Deprivation can be as simple as a trash can flipped over the plants (assuming they're not too big) to ensure they only get 12hrs daylight.
I've seen indoor plants in beautiful, full flower in a warehouse that had enough light that I could view them. And that was their dark phase! No revegging. Tripped me out hard.
