Length x Width = square/ft


10 x 10 is 100 sq/ft
10 x 10 x 10 is 1000 cubic feet

you want to acheive lumens per square foot.

Sometimes I wonder... Just how high *are* some people who post here lol. I am truely completely amazed I am reading a thread that has become an explanation of exponents and physics... And to think almost none of my friends ever thought algebra, math, and science would apply in the real world hahaha...
Delta9Haze420 Reviewed by Delta9Haze420 on . Lighting overkill? My one flower room that i am setting up is around 120sq foot, the clones/seeds/young plants veg under a 400w MH would 2 600w HPS for 120sq be over kill or just about right on? I thinking right on, but other opinions are welcome, the other flower room (for special purposes) has a 1k HPS and is about 80sq ft and they do fine in there, but again, its only a few that are "specialty" plants.
