If you're really tight on money and are just trying to pinch pennies on power, give it a go.
Running cfls I don't think the savings will really be that much, and I'm sure growth will be slower.

I've never used a schedule like that indoors, have used light interruption to prevent flowering outdoors, so the schedule works. I don't think it's all that great an idea for vegging though.
