the more light the better..both grows being even...the 600 will harvest more than the 400...it burns hotter tho 3' x 3' is good for a 600 to get a real nice harvest....

600Watts Hands down, at least 1-5$ more than a 400Watt per month to run. Alot of heat though.. Take your room Length x Width x Height = CFM and get extractor fans with inline ducting on a air cooled reclector that double or triple your rooms CFM in one minute. 6inch High Velocity Inline or some shit.

Depends on how you feel. 1 plant under a 600 will yield the same as 6 smaller plants under a 600.. but will take a few more weeks of veg for the 1 plant of course. but you can do it. no difference. I run two 600s and prefer 4x good bushy plants under each, then have smaller weakling plants based around thoes
