You will want to decide what you are going to measure to determine which
lamps produce the best plant growth. Right away, you should measure the
plant height and perhaps the total number of leaves. Then measure these
same things again at the end of the experiment. Also, make sure that the
light from one treatment is not straying onto the light of another. If
it does, then it becomes very difficult to analyze the results. What
else can you think of that would be helpful for you to measure?
