HappyHarvest i had to bring a couple plants in from outside before, the general rule of thumb is if it's a Christmas tree above its the same below same with bushy plants the roots will be bushy too, then you need to remember for ever foot you see there's 2feet you don't, Bot don't worry to much as long as you make sure to give em a good veg before you try to continue flowering or else you'll get hermi's and no one wants a hemi...
having said all of that you also need to keep in mind weed is a plant has been around for a damn long time and it can handle a bunch of bullshit before it dies. as long as you keep 1/3 of your root mas it should bounce back within 3-5 days DO NOT water for the first 24hours you just ripped the poor girl from the ground last thing she needs is to prepare to distribute nutrients amongst herself.
as far as vegging time goes try to get 3-5 inches of growth before another try at flowering.
Cheers mate i'm sure things will be fine and if all else fails just camp out with your plants and Louisville slugger
