The other cool thing about this is that you can let one go to seed and you will be swimming in seeds as well (though it's tricky to manage the light height because the flower stalk is quite tall). Hydroponics are not just great for food, they are awesome for people suffering from lack of light exposure in winter months. When I lived in Canada, I used to put a 4 foot long plant stand with fluorescent daylight bulbs along each wall of my apartment. I can't remember how long I had the light timer set for (probably 14 hours). It's incredible the difference. These days you can get creative with various LED solutions and probably do even better.
