Question

Answer 1

That isn't a bad choice, but you will still be VERY limited.  Hex tanks are taller and have more water to penetrate, so stronger lighting is needed.  Really, I'd stick with things like Java Moss, Java Fern, Hygro, Swords, lilies, Aponogetons, Anubias, Crypts, Anacharis, Bacopa, Pennywort, or similarly tolerant plants until you get a T-5 fixture.
