||Comparing growth rate of cress watered with different concentrations of fertiliser.
||To what extent do different concentrations of fertiliser affect the growth of garden cress?
||The fertiliser will increase the growth rate of the crees however, higher concentrations of fertiliser will inhibit further growth and kill the cress.
||Plant cress in different container and use distilled water to mix different concentrations of fertiliser and water the cress with their assigned concentration. Let the cress grow under same conditions (light,temperature and humidity).Observe how the growth processes over time and whether any differences can be observed.
