Use google, its all out there but too many differing opinions. Get yourself a safe secure place, tell no one, good soil, good lights, no light leakage, odour control, some nutes (go careful with the nutes), water, fan, good seeds, temp control depending on your climate and just go for it. My first grow was a great success and just researched as I went along, 2nd grow wasn't as good, 3rd grow a disaster but been good since then, last grow yielded enough to last me over a year from 3 plants. Trial and error builds experience and you will research as you go along anyway. The more you read the more you will understand how many differing opinions there are which will just confuse you.
