Flowering mature indoor plants outdoors in later winter/early spring in mild climates

I have a grow planned for this winter to use as a selection process for clones for the summer grow next year. My plan would be to germinate seeds during the first week of November, and veg them in a grow tent in an outdoor greenhouse through Nov./Dec. and bring them out in early to mid January. Where I live, the Vernal Equinox is in mid-March, and the true daylight does not go below ~10 hours, though with civil twilight before and after sunset, the plants would be in light for roughly 11 hours even in early to mid January.

We do not get extreme cold, frost, or a ton of precipitation, and the plants should have a suitably exposed location to get the available sun. I was wondering if anyone else tried something similar, and if so, how were your results?

I’m actually about to attempt something very similar. So I’m going to kinda blend in this thread for some answers myself.
Im building a box for outdoor use with lights and wanna flower during the winter months with natural light.

Ive done it. I vegged some white widow in an indoor tent and placed them outside in March last year. Im at latitude 38 and you can flower outdoors till around mid May. I also have some white widow that I vegged and flowered indoor last year, cut all the colas off and placed outdoors for reveg mid May. They are now in flower and should be ready for there final harvest mid October.
