Dude you seem pretty INTENSE about what your doing! That's a good thing! 400watt mh or hps can be found for around 125.00 to 200.00 it the bulbs that cost.They are as safe or safer than flo's.You got a ballast for every bulb.Increases yeild as well.But from the path your on,look's good! You'll be hunting HID lighting before ya know it! The best thing is! Ya ain't gotta have a license,to hunt'em.
