Like has been said if u dont have a buddy with the already grow room knowhow ur ganna have to do alot of reading and trail and error. your first grow WILL NOT go off without a hitch. Skill only comes with experience. Your ganna have to provide perfect temp/RH, nutrients, no pests, no environmental problems, controlling the smell of that many plants, if ur ganna grow hydro or soil, so many different factors. and you will make mistakes, everyone does, lord knows i have. defieciency here, nute burn there. just all sorts of shit. Anyways i agree i would go with 3 or 4 600s instead of 2 1000's. 600s put out the best lumen per watt ratio, and with more lights u have lots more different angles of light hitting the plants. thats my 2 cents.
