Nothing. He is (wrongly) extending the definition of organic.
So if a plant in the wild was touched by a deer, is it no longer organic? What about a bear, a raccoon, or a human? If it is still organic, can someone explain to me the difference between the mammals that renders one plant organic, & one not?
At the supermarket, if you pick up some organic apples (assume they are truly organic) that someone else had touched, are they no longer organic?
You know I love you, (does your husband know? nm) but none of that has anything to do with being organic. A loose definition of organic just means naturally occuring (& I believe carbon based applies to earthly material) compounds that can be found in nature. You can bring them & use them anywhere you like. The light source, that's debatable. I think of it as more of an energy source. Because the sun, while being organic where it sits, by the time it reaches us is simply energy. Is it no longer organic to use another energy/light source? (I can see both sides of that one)
What you are talking about, to me, falls more under the definition of "Environmentally Friendly," not, organic.
