You know i looked into it, and when you buy the bulb with the ballast, the ballast that comes with it is a 120v ballast, so i dont think it will pop. And i checked it out, the 430 Watt Son Agro HPS light bulb has a 30% increased blue spectrum in addition to the red/orange spectrum needed for fruiting, flowering and budding. So im sure this would be the better choice. (thats prolly why i only have one apposed to six) But if anyone knows if it would work in my 400w HPS ballast, that would be great.
