You will need about 3' between a 400 w HPS and you plants. That much room you might want to consider using CFL's. There might be more options if you search around this site.

i just read the posts on cfl man there is some way useful info there and that opens up a whole new door but now my only other question is how do i figure the electrical use of these versus the hps and to get the equal ammount of light of the 400 hps how many bulbs do you think i need. also how many can i put on one dedicated breaker?
