Im going to grow about six or so plants in my closet and just wanted to know how to grow them good period. I don't have a lot of money either..
Use the search, read some of the many guides already out there, and be prepared to invest at least a couple hundred for 6 or so plants. Then post some specific questions and people will help.
find a space, get an hps/mh light, and read the grow guides (like this one http://forum.grasscity.com/absolute-beginners/73015-grandpas-grow-guide.html )
