no it wouldn't though the sun is a biggillion fifillian times stronger than any flouro on earth. you would get way bigger yields if you just left it out, also to flower a plant indoors you have to expect it will at least double in size if not tripple by the time your done with it. might be a pain keeping it in your house, try putting candycanes and those crome globes on it, you could say it's a christmas tree... there are otherways to force flower, for instance you could move it into a shed for 12 hours a night or put a garbage can over it for the same time, just make sure you have absolutely no light leeks.
