Growing one girl in a closet

[Bam66]

I am growing one female plant outdoors and its began flowering stage. I want to finish it up in my 2x2x4 (2 deep, 2 wide, 50 inches high) closet space. I put it on a 12/12 schedule 1st time last night. I want to leave it inside to finish up and having trouble as a mathematician how many lumens/watts I need for daytime sun. What is the best lighting amount I need? please help I am so overwhelmed.

depends on how big your plant it, tall, thin ,... thick??? bushy??
hum.. 2x2x4
try 3-4 or 5. 23w-26w cfl bulbs 2600k (lightcolor) that's about 6ooo lumen for a 2x2x4 that should be fine, especially if you have reflective walls, if you feel its not enough light add more lights..
