Hey guys, I'm starting to design a new grow room in a one car garage. It's probably about 10x15. I was thinking of getting 4 1000W lights and a tent with a 400W for vegging so I can keep a continuous cycle of vegging and flowering. I'm going to get 2 fans and a continuous line of ducting. Would I need to get 4 ballasts to operate each light? Also, would it be beneficial to add more lights, or should I keep it at 4 for this space? Any tips/comments would be greatly appreciated. Thanks!
