Hey, this is my set up. Just getting started with the 1000w . Been working with a friend that had 6 x 400w lights, do you see a advantage with the 1000w ? I have a 10x10 room with Mylar and the two lights. I'm in veg now with the 1000w and plants are 8"-10" in two weeks. Seems to be doing good. Can you see a difference in plants when you move from the 400w to the 1000w? Any helpful advice would be appreciated.
