Brad,

How you set up your experiment is determined by the question you wish to answer. Also when doing an experiments such as the one you propose, you should have at least three plants per treatment, not one. This allows for simple statistics plus it gives more credibility to your results. If all of your plants in one treatment look similar, you can have more faith that the observed result came about because of the treatment.

Now, getting to the question:

What are the effects of caffine on plant growth?
What are the effects of caffeine withdrawal on plant growth?

The first question of the two would be the easiest to study. You could use different concentrations of coffee ranging from very weak to very strong. Remember, for every con- centration of coffee you need to look at the same number of plants. The reason you should use many concentrations of coffee is you don't know which concentration might be effective. Maybe at low concentration you might see an one effect and at high concentrations another effect might be observed. Good luck.
