Handling mature, newly flowering plants outdoors?

So I've got a bit of an unusual problem. A family member has seven mature plants that are transitioning to flowering, four in the ground and three in pots. They were vegged indoors by someone who wanted them as clones and sold extremely cheaply. The problem is that we're just under 13 hours of light right now and that number is increasing.

I hope to avoid them reverting to vegetative growth, which would waste all the floral development up to that point, and tie up space earmarked for what are currently seedlings that I hope to put into the ground/in those same larger pots once the plants finish.

To try and make it work, I'm going to put the three plants that are in pots into a grow tent with the light off in the greenhouse when it hits 12 hrs of light for the day. I'm currently using the tent to keep the seedlings warm, but they should be strong enough not to need it by Monday, based on the seeds I started ahead of them.

But that leaves the problem of the four plants in the ground. They're not enormous, so I was trying to think of a way to tent them to create the same effect as the grow tent on the potted plants. I could potentially put stakes around the plants and attempt to shade them with a tarp using the stakes as support, or I could use a clean plastic trash bag and put it over the plant.

So I was wondering if anyone had experience flowering plants at a non-ideal time outdoors. How far from 12 hours of darkness can the plant go before it starts to veg? Will a tarp be a complete enough seal to keep light out? Will a plastic bag be too hard on the plant, even if it's only going on for an hour or so before dark? Thanks in advance!

Use thick contractor bags if you can. Just don’t forget to take the bags off as to prevent mold. I have some plants about to finish up in the next 3-4 weeks. Right on time too because we hit 14 hrs daylight on May 10.
 
I have heard that any time above 14 hours light will revert a plant back to veg and that is what I go by. What I would do, is to possibly try using black bags to cover them but i'm not really sure about that. I have a shed I use for those kinds of situations.
When will they start to flower again?
 
It really just depends if they reverted or not, you will know if they did, if you see the veggie leaves growing and not the bud sites. If that's the case, then you might have to wait a couple weeks and revert back to flower. If they haven't reverted, then keep going with 12/12. If they're flowering, you will know in 1-2 weeks.
I'm outdoors. I don't have grow lights.
 
I'm not really sure other than checking the bud sites for growth or checking for new, veg leaves. The general consensus is that you deprive for 12 hours whether thats placing them in a dark garage or covering em up. Or you can let it ride with the seasonal weather.
It has new growth but it's VERY slow. Is that vegging or just normal flowering?
 
It all depends on what the new growth looks like. Without pictures, it's impossible to say. Here is a good guide on how to identify new veg leaves vs flower growth.
They are mostly cut off and and have some purple on them. They were fimmed before I knew the plant was flowering. Leaves are serrated.

Update: It has definitely worked. I took 55-gallon contractor bags and slit out one side on each of them so I could join two of them into one big 110-gallon bag and used one of those for each plant. I would make new ones for each season if you plan to do this and try not to have to do it for very long, but it is definitely possible to finish photoperiod cannabis outside when it might re-veg as long as it doesn't get too hot.
