Play it safe and smart. If you want to use the 430W HPS get a ballast made for that bulb.

Or better yet just get a new 400W HPS bulb that is compatible with your existing ballast.

Care for your plants and enjoy some homegrown with peace of mind.
Happy, thanks for your input. Im really torn, half the people i talk to say dont and the other half say DO IT!. I just went through a whole grow with that ballast and a 400w Bulb. But the bud turned out fluffy . Im thinking i might just have to take the chance on it. Do you really think that even though i had it runny for two hours fine, something can still go wrong? If something were to happen, what would that be? A pop? Ruined Ballast? Im just trying to weigh out the pros and cons.
