I'm sorry but you just can not make that statement. There are way too many variables that you left out and you are not even sddressing the OP requirements. 600w HPS in a 4x4 tent Heat is always an issue.4x4 tent with 600w hps coolhood with a 6inch 470m3/hour fan with carbon filter and ducting heat is not a issue
I didnt mean it buy a 600w in a 4x4 heat is never an issue but i know people who have had a 600w in a 4x4 and had no problems, they even had a set up much stated almost identical to the one i said and heat was fineI'm sorry but you just can not make that statement.

it would be in a separate room (bathroom to be more specific)Stick with CFLs man, or a 250 HPS Max you'll be able to manage that much better... at the end of the day its down to you but you'd feel gutted if you went 600 or Even 400 HPS and temps are to intense ..out of interest what kind of reflector do you plan to use and would noise be an issue for you ? - STELTHY
maybe we should of asked this firstWhat is your budget for lights, fans etc etc ? - STELTHY
