Please, not a sprayer made of copper. It only takes 3 ppm, or 3 micrograms of copper per ml of tea to kill a bunch of the beneficial bacteria.
Or if copper is used, it must be carefully lined and you must be careful to not scratch or damage that lining. You wouldn't drink from a cup made of copper, don't make your beneficials do it either.
