Ive recently been building a hydroponics system that I'd like to use to grow vegetables. I bought a float switch to operate the
pump, but when it arrived it stank of mothballs, and even unopened in the package had some kind of white powder on it, possibly the source of the odor. I may by a timer for this setup instead, but My question is whether or not the float switch is safe for use immersed in a solution that will feed plants that are meant to be eaten. Thanks.
