At the top of the pages here there's a link called 'Search'. Click on that, and use it. All the info is there for you in Searchland. Just look for the hundreds of other posts with the exact same questions and find the threads with the answers.

Alternatively (or in addition to using the search feature), I recommend a book: The Cannabis Grow Bible, by Greg Green. It'll tell you all you need to know, AND you'll be helping out Greg Green at the same time, which is bound to be good karma.
