That will be fine for your seeds-how i started mine, and now ive got 14 6 foot bushes and over 50 clones happily budding. Only use it early on though, or put the bulb quite close to them-fluorescents tend to make the seedlings stretch and grow weak stems-a few weeks outside exposed to the elements works a treat at strengthening them up.
