If you insist on trying to continue to grow this plant your gonna have to learn ALOT fast. A question first, how long until you were able to put the roots into ANY form of water?
Ok first if you pulled it out of the ground then you left ALOT of its roots behind. thats the first obstacle to overcome. All of the plant that can no longer be sustained by the existing roots will most likely die(starting with the oldest growth). If she wasn't in flower you could mist her and place a large clear plastic bag over her to retain the moisture(Can still use the bag but don't seal it tight), but to do that durring late flowering would pose more problems than it would solve(mold etc.).
Additionally be sure to keep it out of HOT locations for a week or so to allow the roots to recover.
Second that girl looks like she has been in flower for quite some time. find you a GOOD magnifiying glass, or mini micro-scope and look carefully at the trichromes
shows a good photo of them. what color are they on your plant? If they are ALL clear you might have a chance to take her on to full maturity, BUT don't expect her to grow much more unless you can give her IDEAL conditions.(a costly prospect) If the Trichromes are still mostly clear(not milky or amber) then there is a slight chance you can get a little more bulk on her before you finish killing her(yes finish, you started the instant you pulled her out of the ground. should have dug out a good portion of the roots with her.)
If the trichromes are mostly milky/amber then the time for growing is over and you may as well cut it down cure it and enjoy.
After you have read your responses and determined where the plant is actually at stage-wise and have determined which of the two actions your going to take(try to revive, or smoke her) then go thru this board and learn how to grow from the experience available to you here. There are people here who have put alot of thought and effort into finding inexpensive ways to get a NICE yeild from rather small spaces.
Good luck to you
