This is a guide that puts everything in plain and simple English, and doesnt go to deep into advanced botany and gardening. I find this one to be the best guide out there.

Growing marijuana indoors is fast becoming an American Pastime. The reasons are varied. With the increased
interest and experimentation in houseplant cultivation, it was inevitable that people would apply their knowledge of
plant care to growing marijuana. Many of those who occasionally like to light up a joint may find it difficult to
locate a source or are hesitant to deal with a perhaps unsavory element of society in procuring their grass. There is,
of course, the criminal aspect of buying or selling grass; Growing marijuana is just as illegal as buying, selling, or
smoking it, but growing is something you can do in the privacy of your own home without having to deal with
someone you dont know or trust. The best reason for growing your own is the enjoyment you will get out of
watching those tiny little seeds you picked out of you stash sprout and become some of the most lovely and lush of
all house plants.
