I have been hearing a lot of talk about people using 400 watt bulbs in 600 or even 1000 watt systems In fact my friend uses a 1000 HPS bulb in a jimmy rig 1,500 watt system.... So please all im asking is why when you ask about sticking the wrong sized bulb in a certain sized system do people get all frantic... but then there are people who do it anyway with no apparent problems????? IM lost GC help me understand lol
