The three plants (spinach, radishes, and lettuce) were tested against red, orange, blue, green, and violet lights. After the computer aged the plants to 30 days under normal growing conditions and under the given color light, it spawned a plant. I measured the plant (actually 3) then averaged the heights.
What I found was that all three plants grow generally the same as each other. The only major change in heights happened because of light color, not species. All plants grew a lot under red light. It dipped down to orange, and continued to dip when under green light. Under blue light, the heights were close to the heights under red light. Going to violet light means growing less. A graph and table showing exactly that are at the bottom.
One very interesting thing I learned was that the reason plants grew less under green light involve their color. Since they look green to us, that means they reflect green. If they reflect green then they don't take it in as much. Therefore, green light makes them grow less.
