If I was just starting out, then I'd probably get set up with a tent growing package from AC Infinity -just because they seem like a great company and have all the gadgets that you need to get you started without having to shop around a lot.
After that, I'd get some reputable soil mix (like Fox Farm Ocean Forest, Or Roots Organic or Pro Mix, for examples). Start the seeds out on a 16 oz party cup until the root system fills it up. After they are well-rooted, transfer them into some 4-gallon (or thereabouts) garden pots. Keep the soil moist but not wet.
Monitor things like pH levels and don't get caught up in the "secret formulas", boosters and witches brew out there. Just stick to a basic fertilization regime such as Jack's 3-2-1 system.
And last but not least, make sure you start out with some good seeds, because genetics is everything. For starters, try some feminized seeds so that you are guaranteed of getting a female plant. After that, try some regular, photoperiod seeds.
I also think it's good advice to stay away from the trend of growing automatic flowering cannabis....read my signature.
Good luck!
