All of the plants were pepper plants because if they weren't all, your experiment wouldn't be valid. You can't compare pepper plant to say tomato plants.

If you were doing an experiment to see if plants grew better in direct sunlight or the dark, all of your variables have to be the same.

First, we need to define exactly what is an experiment.

An experiment is a set of systematic processes used to valid and prove a hypothesis or a system of hypothesis. All experiments need to have validation to ensure that results are reliable, other way, all efforts to demonstrate the hypothesis will be not trustful. Through experimental processes some behaviours are observed with a cause-effect relation between two variables, which are part of the purpose of the study.

So, before reproducing an experiment, all variables must be identified and defined, to be sure that it's been studied the right things. In this case, the study is about pepper plants, this is one of the variables, the sunlight is the other variable. Therefore, in the experiment, pepper plants are present because the study is towards their reaction to sunlight, the study cannot use tomato plants, because the hypothesis is not about them.
