A Biological Question - Which fertilizer is better: brand A or brand B?

My Hypothesis: brand B, because it contains added plant vitamins.

The Experiment:

• Use 3 identical plants.
• Give water to each plant equally on Fridays.
• Plant 1 will just get water.
• Plant 2 will get water with fertilizer A added.
• Plant 3 will get water with fertilizer B added.
• Measure the height of each plant (in centimeters) on Mondays.
• Run the experiment for 2 months.
• At the end of the experiment, the best fertilizer will produce the tallest plant.
