| I am not sure how rough copper is with orchids, but I know it very rough and deadly on aquatic plants and coral reefs. I owned a pet store many moons ago and I would always have to check the coral tanks to make sure that some kid wasn't making any wishes and throwing pennies in them. One or two, not a problem. But if they built up then it would cause problems with the corals and live plants.
Again, this is my experience with copper and aquatic plants and animals. I am not sure if it will have the same results with orchids. |
