+1 for the reptile lights, much cheaper than an extra MH in the long run.

I use UVB cfls for the last 3 weeks, they put out 10% pure UVB at 18w

I have them on timers for 30min every hr for 4 hrs, over 'peak' daytime to simulate the sun but not over do it(as UVB breaks down THC and the buds, you end up with lower yields if too much UV is used)
