When I was at home, I would grow a garden every year. As I was sitting at my desk eating an orange and drinking out of a bottle of water, I had an idea.
I happened to think "Hey, why can't I have a garden here?" After thinking it over, I realized that my dorm wasn't large enough for a decent garden, and I really didn't want to spend a lot of money on seeds.
I started trying to find ideas for a plant that produces fruit or vegetables in a dorm that would be long lived, have readily available seeds, and didn't cost too much top start and maintain.
Thinking this over, I was spitting my orange seeds out into the garbage can, I started thinking "what good are those going to do going to a landfill?"
For me orange seeds seem to fit the bill:
~Orange trees might produce the fruit I want***.
~Orange trees live for years.
~Oranges are covered under my school's meal plan, so I have an almost unlimited supply of seeds.
~Most of the items needed are recycled and are free or low cost.
~I'm already paying for my meal plan, so why not?
***NOTE: This is a big "might". Most indoor fruit trees never produce fruit. Most don't get enough light and don't get large enough to fruit. Your chances get better if you put your plants outside during the summer (and maybe winter if you live somewhere insanely hot).
