The most important part of designing an experiment is ensuring you have valid controls and are minimising the effects of any other variables that may affect the result (confounding variables). You are investigating the effect of light intensity on the rate of germination - so light intensity is your independent variable. Therefore, any other factors that may affect seed growth (think temperature, soil moisture, soil pH, oxygen concentration, type of soil?) must be kept constant in both groups to ensure your comparisons are valid. I'm assuming from your question that you're only testing the seeds in two conditions (low light intensity vs high light intensity), as opposed to a continuous range of low light intensity to high light intensity, meaning that you will only have two experimental groups to test. So with all that in mind, think about what design and apparatus you might use to do this experiment; and, most importantly, what measurements you will take.
