I have twelve 400watt hps ballast and lights these are regular shop lights, and ballasts. the lights are vertical unlike the fixtures Ive seen here that are horizontal. i only plan to use one light for now because of room and energy. anyway the question is are these lights sufficient for growing. how far apart from each ballast and how far from plant tops. i am a rookie at indoor growing any suggestions would be greatly appreciated. thank you
