Yeah. You need to wait until fall unless you can figure out how to put the sun on a timer. That's the trade off I suppose. With artificial lights, it's a faster grow, flowering is controlled by you, but that electric bill is gonna sting. That sunshine don't cost you a dman thing but it sure does take it's sweet time.
Look, please don't take this the wrong way, and I barely know shit about growing myself, but I would recommend that you do some more work/reading/learning on your own. It seems that there is fundamental info about growing that you haven't learned yet. The GrowFAQ is very helpful.
Best of luck with your grow.
