For about two months, I had some wonderful little plants surrounding my Francis wall. I bought a 'forever sun' lamp which I kept on 24 hours a day (see the light shining from the corner) because this space had no natural lighting at all.
However, my once-little happy plants began to change. They were not doing well.
They were sick, obviously, and needed care. I tried variously things over the course of a few weeks… but nothing worked.
Then, I thought about grief.
"Oh my gosh! Of course!" I thought, "The plants are not getting darkness now at all, are they?"
I went to the literature and found out that, indeed, plants require darkness for photosynthesis. A carbon reaction reduces CO2 to form carbohydrates and thus to release oxygen. This happens only in the darkness of the night. The darkness is also necessary for photoperiod, the process by which the plant prepares itself for flowering, for blossoming.
Talk about a 'doy' moment of perspicuity.
When I read about this process for plants, I sat down and cried. Nature, the Great Teacher, thank you, thank you.
We need the darkness to be whole, to be healthy, to blossom.
My plant, now, after now being exposed to darkness again looks entirely different.
...And so do I.
