nice, i just got done growing the sour cream out under a two fifty hps, and was super happy with her.. got a lil tall in flower, i would say it atleast tripled in size from the time i flipped her, and the smoke was great.. the smell of the buds is kinda hard to put a finger on, at first they just have an odd sour smell to them, but once they go into my grinder, i find the haze smell really pops out at me.. the smoke is nice, not too racey like a haze, and not pure couchlock like an indica would be.. it was very well balanced between the two, and of course i didn't take any clones off of her although i still have a few beans left of it.. i let it go to about 13 weeks or so and i think the timing was pretty good..
look forward to seeing what you get out of it under the leds.. good luck with the grow..
