i agree w/ part of what mega octane 12 is telling you , but do consider how tall the plants will get when deciding between 600 / 1000 w. lights . penetration is very very important . lots of 400/600 might be nice for cloning tables / scrog / sog but if they end up trees the lower parts of plants are gonna be fiendin for light where they wont be w/ 1000's .
do lotsa research and learn from everyone on here's mistakes so you don't havta make them all yourself as they can be incredibly costly .
peace
