Overall, the radish seedlings grew in all containers regardless of the colour of light.  However, both the green and red sprouted out of the earth by day three.  On the fourth day, seedlings growing under yellow and blue light emerged.  Growth of the seedling exposed to unfiltered light was not detectable until the sixth day.  By day six, seedlings growing under red and blue light achieved the highest heights followed by green and yellow.   Over the next four days seedlings growing under green light surpassed the blue.  At the end of two weeks the heights of the seedlings in descending order had grown under red, green, blue and clear.

These results are displayed in the following graph (Figure 1.).

These are the results of the daily growth of the plants
