The best hypothesis for the experiment would be:

If salt water is used to water plants, then the plants will not grow as tall as those watered with tap water.

This hypothesis is clear, testable, and predicts a specific outcome based on the condition of using salt water versus tap water, making it suitable for scientific investigation.
