I vaguely remember the following information from 10th grade biology:
If you shine only blue or red light on a plant, it will look wonderfully healthy but actually be dying. It will die seemingly all of a sudden.
If you shine green light on a plant, it will look like ass but actually be very healthy.
Am I completely crazy? Google is not even a mild acquaintance tonight.
You got it backwards, if we’re thinking along the same lines. Plants look green because they reflect green light and absorb red. So if you shine red light on them, they’ll absorb all the light, getting the energy they need, but they’ll look black, because no light is getting reflected to your eyes. Similarly, if you shine green light on them, they’ll look happy and normal, because all the green light is getting reflected back to you, but since they’re not absorbing any light energy, they’ll die.
Not quite. According to this No single light color is detrimental to plant growth (within the limits of the experiment).
Well, it’s a bunch of kids, but it’s all we have to go on…
Anyway, thanks for the responses.
Hey, kids can do good science too.
