Go with 600 watts, you get more lumens/watt and better dispersion than 1,000 watts. If you're going with a massive setup like that make sure you've got good electricity, I'd highly reccomend looking into the new digital ballasts.

Buddahbear Reviewed by Buddahbear on . 4000-5000 watt grow? Real quick background. I set up a 3000W grow almost 2 years. It was an aero system. got through the cloning process, sexing and I think into the flowering process. But then I hit a snag and never finished the grow. FYI, dont leave hoses on and flood your space. So now I have a new space which is more secure and fool proof. I have calculated that I can use about 5000 watts of lighting to keep my electric bill in check. would I be better off using 5 1000watt bulbs or would it be better Rating: 5
