Is your flower room separate from your veggie room? Is your room CO2 induced with a controller? The reason for such a high wattage is because the CO2 makes the plant intakes twice as much nutrients and works twice as hard. (At least that's what i read) Im just trying to see this theory proved before I go out and spend $3500 on a new grow op.you would be better off with 4x600w in that space.
i run 3kw on 38sqft and its just a bit to much.
