They're not very efficient so the WPG rule doesn't work as well with NOs. VHOs are good lighting though. How many do you have? if it's two, I would consider getting a bit more lighting for any plant that requires 'high lighting' personally.
I'm a newb to plants myself but I did deal with all kinds of lighting with my reef, I'm sure someone that knows more will correct me if I'm wrong.
edit: Oh, you said actinic.. a super actinic, eh? Assuming that's a 50/50, that really isn't suitable for freshwater plants. Your tank will look a bit on the dark side if you only have two and a lot more of that actinic (taking up half of the output) is being wasted than would be on a normal daylight bulb..
