check out the link in my signature. If you are trying to grow 1-2 plants you can go down 2 different roads. It depends on your budget. If you have 300$ you can easily setup a premier closet grow that will produce some dank buds.
You need
soil - ocean forrest by foxfarms / cheap substitute is miracle grow (soil is important)
lights - (cfls are basically those spiral lights you see now days. You have 2 basic spectrums. 6500 k daylights are used to veggie the plant 18/6 light cycle, (aka when u start).
you then switch to 2700k lights when flowering at 12/12 cycle.
you can veg as long as you want, depending on space. The more light the better. And both of these spectrums will be on the box of the bulbs at the store (check out walmart, home depot, lowes, target). If you use the cfl method buy a power strip/surge protector and bulb to ac adapters. where u plug your lightbulb into an outlet directly. there you can also buy splitter and this and that. cfls use as many as u can. lights alone should cost you 50$ if you are gonna be really growing a plant.
ventilation is imprortant, have constant air movement, and you can build a carbon filter/scrubber for cheap (google the zen model scrubber) to eliminateo odors
if you want 2 dank plants buy a 150watt hps system. it has an enclosed ballast, you can get it at your local hydro shop.
also get nutes, foxfarm preferably, grow big, tiger gloom, big bloom.
I mean you get what you pay for, and if u spend a bit of money, do some reading, you will have a premier setup for cheap, and your plants will reward you with nice yields.
probably a lot i missed lemme know if u have more questions
