400W HPS = 50,000 lumens
4 sq ft grow tent = 12,500 lumens per square foot.
Will this be okay if I keep my temps cool?

Are you asking about a 2'long X 2'deep X 5'tall space?would it be okay to use 400w in a 2x2x5,7 for only the flowering stage
yes i am. i would use cfl for veg then use 400w for flowering.Are you asking about a 2'long X 2'deep X 5'tall space?
im doing the same thing pretty much but mine is 5x2x5.... How many cfls are you using for veg?yes i am. i would use cfl for veg then use 400w for flowering.
well i was thinking about starting off with two 42w and then just adding more as they get bigger. i did that before but i dont have that much room this time.im doing the same thing pretty much but mine is 5x2x5.... How many cfls are you using for veg?
