Click on the link in my sig called "OG Growfaq" and read through the relevant articles. Most beginner questions are answered there in short, easy to understand format.

First thing to do is decide where your growspace will be. Once you know the size of it, you can begin to form a growing plan, addressing things like what system, soil or hydro, how many plants, how big, ventilation, etc.

Once you have your plan formulated post it up on this thread so I and others can critique. Read through the Growfaq first though for the basics.

Here is another good link to read for beginners.
