The Grass Doctor

Does anyone know of a plant seed that will grow REALLY fast?

My daughter has a science fair project due in 10 days. She needs to find out if plants grow faster in sand or in dirt. With little time left, I did not want to end up with nothing growing. Any suggestions on what type of plant seed or even maybe grass seed that will grow in time?

3. If you use a heat lamp, marigold seeds can germinate within 3 or 4 days, if the temperature is at least close to 80 degrees or so. If you don't have a heat lamp, a flourescent light placed within about 6 inches or so should suffice.
4. I'm sorry I don't know :( maybe check the Library?
5. Chia Pet will gow fast haha
6. Try radish seeds. They germinate in a day or so and are ready to be picked in about 21 days. Grow some in a 10 gallon fish tank with the seeds along the glass and you can see them under the soil. Use nice soil about 8" thick. don't over water. This may be a way to go. This along with bean sprouts was all that I could find. It is a little out of my realm.
7. I plant tomatoes and green beans, but I am not sure of growing time wise though?
8. most of your beans, if you keep it uner a light and wet, grass, Rye grow pretty fast too MO
