oops my bad

in a 4x4 area add the second 400 and it should work out great..

I run 1 400 Hps in a 3x4 box and it works very well. probably not as well as LOC NAR1958 and his 1000 watts.. LOL
Bender Reviewed by Bender on . Which is better? (2)-400w hps or (1)-600 or 1000? Hi. I currently have a 400w PL light setup. I was thinking to augment this with a cheapo 400w hps (used, rebuilt, etc. off ebay or inside sun). Certainly the 400w hps systems are affordable. I wonder though - is it better to have (2)-400's or (1)-600? I'm afraid to go with 1,000 as I'd have heat to deal with and wouldn't be able to get the light as close to the plants anyway so it might be counter-productive. My space is about 3.5 or 4x4 feet. Or - hopeing to not have more than 4 Rating: 5
