Se monta un dispositivo experimental que pueda probar nuestra hipĂłtesis. Si hay otros factores que puedan influir en el crecimiento de las plantas (otras variables), se controlan todos y se aplican de forma idĂ©ntica para todas las plantas que se van a estudiar (luz, humedad, tipo de tierra, agua de riego, etc.). Variamos Ășnicamente el factor que queremos comprobar: los nutrientes, es decir, utilizamos semanalmente mĂĄs fertilizante para unas plantas que para otras y en algunas no usamos nada. Podemos utilizar fertilizante lĂquido disolviendo las distintas dosis a emplear en la misma cantidad de agua. Anotamos la cantidad de fertilizante que le echamos a cada planta.
