Ok so I have a dual 400w pfo m58 ballast. I know I have asked about bulb choice for this ballast before but is there any bulb that can be over driven on this ballast. Such as a radium on other types of ballast. I know my selection of bulbs for this type of ballast is limited but I'm just wanting to get the best color and growth combo with this ballast.
