The length of time will be determined by what
kind of plant you use. Some plants grow faster
than others. I did a quick web search to find
good plants for science fair projects. It would
be nice to find something that grows faster so
you don't have to wait as long.
I found this website, which uses a Brassica
species. Cabbages and broccoli are examples of
Beans, radish, peas also seem to be good (and
cheap!) choices. Good luck!
