Experimental Hypothesis and Predictions

My group has hypothesized that the plant that is "rained" on at a slower rate will grow better because steady and gradual is a better condition than fast and abrupt. I, myself, am predicting that the plant that is "rained" on at a slower rate will grow faster than the other. In nature, a slower, plentiful rain always has a far better effect on plants, etc. whereas a sudden rain could lead to washing out plants and animals, causing danger in the ecosystem. I am a little worried that by doing such a sudden rainfall that some plants in that group may not grow, but I think that as long as my group is careful about how much water we add each day (150 mL per plant) that everything should go smoothly. I am not as worried about the condition of the plants that will be "rained" on lightly because the rain will not be so rough as to destroy them when they are just seedlings. I cannot wait to begin this experiment because I am anxious to find what is going to happen, and if my hypothesis in the first sentence is right.
