T8.........is this a good light?

A FRIEND OF MINE HOOKED ME UP WITH A BALLAST THAT HAD TWO 4ft f30t8 daylight hg HOOKED TO IT. I HEARD OF T5 BUT NOT A T8 AND WAS WONDERING IF IT WAS A GOOD HOOK UP. I USUALLY JUST USE CFLS. I HAVE A CALI CON BUDDHA TAHOE OG THAT JUST POPPED AND IM THINKING OF GROWING A MONSTER IN MY CLOSET. THINK IMA HANG IT HORIZONTAL AND JUST ROTATE THE PLANT TILL IT GET LIKE 5 OR 6 FT THEN PUT IT IN FLOWER. BUT ANYWAY I GOT OFF THE SUBJECT. IS THIS 4ft f30t8 daylight hg GOOD.

Free s always good ImO, personally, I run a t5 H/o setup and they are amazing!, T8's for free = can't go wrong. they'll add light and use a small ammount of electricity. Would I PAY for one, not if I could afford to get t5's instead.
