Hey everyone, I've done a few outdoor grows and a couple closet grows, and I've decided to amp it up and convert part of my basement for growing. I'm going to have three 4 foot by 4 foot bleachers, each with 18 plants. I have two options for lighting, which is either three 1000w HPS, or two 1000w HPS and two 6 foot light movers. From everything I've read the two ballasts and light rails should give me the same yield as the 3 ballasts, but I figured I'd check on here and see what all of your collective experience has to say. Thanks in advance!
