growing weed isn't hard. i would ditch the yard soil though.. just because of the bugs in it.. not because of quality or anything.. and get some plain old soil that doesn't have any chemical fertilizers in it. i used scott's. dirt is basically dirt.. until you add stuff to it.
anyways.
change the soil, give it nice light, don't over or under water it. and give it some nice organic fertilizer, and you'll be rollin'.
just a personal word of advice ..in my opinion.. unless you are looking to grow and sell.. just try to start simple.. cfl bulbs work great, i just harvested 4 oz of premium bagseed bud from cfls.
and if you are growing for personal use (if you don't care about weight, just quality) think about doing a water cure.. it takes less time, and you really come out with a superior quality of weed.

toke! toke it up, man! good luck.
