  I'm doing an experiment for biology using artificial light.
After germination they appeared to be the same size when I 
placed them under the different color lights.  I used clear, 
yellow, red, green, and blue.  My blue, green and red are 
growing the quickest. Isn't this exactly the opposite from what 
it should be?  Can someone please tell me what the problem is?  
Is it because I used bean plants rather than another type of 
plant?  Also, why should the blue and green grow the slowest, or 
should red grow slower than green?  Thank you.
