new to growing

i would like to set up in a closet 3.5feet square what do i need to get started
such as lights fertiliser and other equipment that i may need and how do i go about it thanks

You'll want to check out the SCROG or screen of green growing method.

well it depends on how much money u want 2 spend
if u want to go on the cheaper side lyk me get sum flourescent lights found at a ordinary home depot or w/e is in your area and hang them or put them within 3' of your plants AFTER they've ben successfully sprouted
for fertilizer get an all purpose 20-20-20 at a local nursery cant go wrong w/ that and i assume u kno how 2 feed em and wut not
your going to need a ventilation system but for the first two weeks theres no real smell so u wont need a filter yet to cover the smell but air flow IS ESSENTIAL just as light and nutes , air , light , water, and nutes are all the real essantials a normal house fan that is able to rotate can be used before u get a filter to make sure the plants arent grown to be lanky and weak thwe air blowing on them excerices the stem and guides them to become strong plants able to handle heavy sticky bud growth
now its hard to really giv sum good advice w/ out some more specific details on the room get a basic set up going and it will be easier to tell u wut u really need 2 work on.
keep me posted and good luck growing, pics would help a great deal

seems like u need do do some reading and research first...

yea wut he sayd all the stuff i sayd can be easily found out in a simple grow faq and they will go into it with better depth, just google growing weed
