I transplanted to a five gallon bucket and she was nothing but a big root ball. So I gave here a good wet down and now she has enough room to triple her roots I'm scared it just makes it more obvious sitting outside. Plus after harvest she will be to big to revert right.
Some considerations:
1. Like someone mentioned, you put that plant outside and she's gonna stress out, most likely drop all her leaves. It has to be acclimated to sunlight over time. Of course I'm in Texas and we not only have high light but constant heat.....you're up north so your mileage may vary. If it was mine, I wouldn't do it. One "aw shit" and it's over, and you have a long way to go,
2. Once a plant goes into a flowering mode root production is put on the back burner. The plant is putting its energy into flower production, not roots. Root production should have happened at the beginning, not towards the end. That's how an annual "thinks", and that's what it does. You need to upcan before the flowering response for the best results,
3. If you're subject to winds and storms....good luck! Like the light, your plant is not acclimated to the stresses, pressures, that come with outdoor gardening. My outdoor gardens are beat up by constant gusty winds and storms...it's really a PITA and will bronze the leaves if the wind is bad enough, will split the crotch as shown here on this sativa that went thru a thunderstorm. In spite of a nasty split trunk (4 main colas) it did fine.
4. You have the option to top her and I would surely take out the tallest lanky stem,
5. High P foods contribute to the stretch. Stay away from them.

6. If you have a security issue and that includes peace-of-mind, keep it inside.
I've grown Dalat Viet. sativa indoors. Here's a photo of part of the garden where it was out of control so I put it at the perimeter of the garden and let it grow right past the lights which were raised to the max, about 6'. It was topped numerous times during flowering and it produced just fine.
You are the master of your garden and must take control.
Good luck,
