Stainless steel is better, less reactive, but not necessarily safe. All metals, just by their very nature, will leach elements in an acidic environment. These plants grow in an acidic environment. In this case, you're trading copper ions (which are definitely more toxic) for iron, chromium, and nickel ions being introduced. However, nickel is a known carcinogen.
Yes, stainless steel is used in many applications surrounding food, including utensils that you put in your mouth. But that momentary contact vs weeks or months of sitting in an acidic environment do not come close for a relevant comparison.
I guess the big question is, at least in my mind, why do you feel that grounding the plants is necessary? Billions upon billions of living and thriving potted plants prove that it is absolutely unnecessary.
Don't get me wrong, they're your plants to do with what you wish, but I can find very little evidence to support this claim that grounding is beneficial. The few articles I do find are laced with ads for ready made grounding devices you can purchase, give instructions on how to make grounding devices to plug into an outlet (yikes! DANGEROUS!), give references to "experiments" conducted, but give no data about the before, during, and after, or refer to people they claim are experts on the subject, but give no links to their online information, nor citations to their published works, and none of them have any mention of this being applied to carnivorous plants. That is the main focus of your question, and there is plenty of published evidence to, 1. support that these elements are toxic to carnivorous plants, and, 2. these elements will leach out in an acidic environment.
I'm not saying it's BS, but I'm getting a feeling that this is the equivalent to the ads for "X-Ray glasses" that used to be on cereal boxes when I was a kid.
If you can conduct and document an experiment that proves the benefits of grounding your potted plant, great. You'll be ahead of the vague claims of success I could find.
Everything happens for a reason. Sometimes the reason is that I make bad decisions.
