4 x 600 watts or 2 x 1000 watts ???

I don’t think anyone from 2014 is going to answer. And I only have 2 600’s in my flower room. Grow some pretty big bushes with them sometimes.

SNAP!!!! Damn I didnt pay attention I was just looking for new comments on combining 600s n 400s

Four 600 watts = 2400 watts
Two 1000 watts = 2000 watts
On top of being more watts, you will have way better light coverage.
Dont dim your bulbs, yes you can do it, but your bulbs are going to age faster, and not run at correct efficiency as they should. Bulbs are designed to be ran a certain wattage for maximum spectrum and all that good stuff.

I did the mistake of dimming the bulb for a grow some time ago.. The plant stressed out to the point of Hermie and it was a total loss of her in the end.. ( you can't get a female back from herm in this case) It is hard on both bulb and plants and not worth the risk in my opinion.
Start off with 400 bulbs and kick it up from there for safer results. That's my 2 cents.. Happy grow!
