I wouldn't do seeds unless you have a way to bring the seedlings close to the light. They need to be no more than a couple inches from the bulbs. Given that, I'm not sure what value you're getting by putting them in a glass container. They need air circulation, which they wouldn't get in there, and it may end up too hot.

There is a forum called "Garden Junk". Some seriously creative people over there who might give you some ideas on what you can do with it (though you'll no doubt get one or two telling to you plant a fairy garden in it, LOL)

Personally, I'd use it as a terrarium for houseplants (after repairing the crack(s) first) rather than a greenhouse for vegetables.

As loribee2 said, veggies need a high amount of light. When people use flourescent lights they keep the bulbs only 1-2 inches away from the top of the plants. If the bulbs are any higher it leads to "leggy" plants. Good air circulation is a must to prevent damping off (fungus) problems. And it seems like watering the plants would be a bit of a pain. Plus, it just doesn't seem big enough to start many plants to me.

Just buy a new fish tank , that's it, If u have money of course.

You always need to update your aquarium, always. I do this every few years. And just recently I changed it to a new huge aquarium, and bought more fish so that everything was beautiful. But recently I read about the fact that there are worms that can live under water, in my opinion, I read here arcreef.com . So, I called a friend and immediately said that I want myself an exotic worm, so that it lives near my fish and pleases the eyes. He did so and now I admire the beautiful view.
