if you plan on staying small I would go with a 400. Th extra 200 is nice but if you have problems with heat you might as well downsize.
trinitybound Reviewed by trinitybound on . 600w HPS vs 400w HPS I think I sort of overshot and got the 600w on the assumption that it produces more lumens per watt and that I would probably need it I was thinking about downgrading to a 400w HPS since my growspot is rather small and I keep getting heat issues can ya take a look at my logs and tell me if I would justified in getting a 400w and selling my 600w?
