You need to think of a physical factor that affects the growth of a plant and then think about how this might affect the growth. You then write it as a hypothesis by stating how you believe the two variables are connected.

By analogy, say I was testing the effect of weights on springs. My hypothesis might be, "As the weight attached to the spring increases, the length of the spring also increases".

You can extend the hypothesis by saying how exactly you think the dependant variable is affected by the independant variable (e.g. the extension of the spring is directly proportional to the load applied) but you don't really have to do this.
