Any one know how to do the 12 mark question in btec applied science exam on 3/5 . The question about the effect of mineral water and light intensity affect the growth and plants

I wrote
1.using ph meter and light meter to the measure the light intensity and ph of soil
2.divide the field into grid (10x10 square)
3.give each square a number
4.use random number generator to generate 10-15 numbers and match the number of the square
5.count the number of plant and calculate the percentage cover
Repeat 1-5 in others corrdinated square
6.try it in diffierent condition such as different pH and light intensity, the number may decrease for those two plants.
Am I doing correctly ?

i just talked about growing both of the seeds in the same plant pot and then measuring the root length after 15 days, i dont know if it is right though.
