Take six plants and divide them in to two groups ';light'; and ';dark';. The ';light'; groups will receive 12 hours of light a day while the ';dark'; groups will receive no light. Measure the height of each plant every day for one week. After that week you can swap the groups so that the ';light'; group receives no light and the ';dark'; groups gets 12 hours of light a day. Measure the height of each plant every day for one week.
