How long do I need to do a science project using plants under different color lights? My goal is to see if the different color lights effect their growth.
Answer 1:

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 Brassica species.


fast plants

Beans, radish, peas also seem to be good (and cheap!) choices. Good luck!
