T5's are great for early stages of plants.. but to use T5's the entire life of the plant will produce... mediocre results. However, if you can get specific spectrum bulbs for your T5 fixture, you'll do much better.

HiD is the way to go! But you must weigh out the circumstances and be sure that you are able to safely and properly setup HID without problems.

Cheers,
