Not tryin' to hijack this, but when you all say he can get 4 to 6 plants with a 400w, is that SOG, SCROG, or 5 or 6 footers? I'm having a bear of a time trying to figure out how many plants I can reasonably grow in a room with 5 400w lights. I have 5 MH and 5 HPS, so vegging and flowering will get the proper lighting, just have to swap out ballasts. I am going to FIM/LST them, but they will get 5' or better, and probably 4' dia.
