Well, yes and no. Yes, it will flower your plant, but as hard-on said, it will be a very low yeild and of low quality. Not worth all that time and energy you put into it. I would get a 150 bulb, and a 75 bulb for good results. I've used a 150hps for 1 plant before and the yeild was, ehhh...okay I guess, but not something worth my time and energy. So try and get more light, or grow only 1 plant under a 150hps, or don't let your plants get quite as big, keep them smaller. Good luck!
