If you were doing SOG i would say that 1000 on a light mover would be sufficient. Al B. uses 1000 over a pair of 4x4 trays. for those of you who cant add thats 1000 covering a 8x4 area.
Al B. uses 3x3 trays (actually 900mm trays which are 2.95"x 2.95")... He made the correction in his post, but Ive seen a lot of people still saying that he uses 4x4 trays.. A 1000w hps over 2 4x4 trays (or a single 8x4 tray) works ok, but not great, because you will only yield slightly more (and sometimes less) than having just a 1000w sitting over a single 4x4 tray for the whole 12 hrs a day.
