I think I'm going to try an experiment. Last year I wrote a post about how I thought I could keep a plant alive in a closet by giving it sugar water. The whole point of sunlight and photosynthesis is to change CO2 in the air into glucose. If I give the plant glucose directly, perhaps it would grow just fine. I don't know if sucrose (table sugar) will work, but sucrose is just glucose and fructose bonded together.
So I'm going to try it out. I'll let you know how it works.
