Sow or root plants - not one plant, a group of them - in identical soil, in identical containers. When they have reached whatever stage of development you think is right to begin the experiment, divide the group in half. The control group will be treated according to horticultural instructions - whatever is recommended for that species. The experimental group will be subjected to stress. If more than one kind of stress is contemplated, you must further subdivide the experimental group and label clearly, or mark in some way as to which group is subjected to what kind of stress; e.g. Group W is overwatered; Group L is deprived of sunlight; Group S is allowed to become pot-bound and given no plant food. 

Every scientific experiment needs a control, a method and a pre-specified duration.
