Out of curiosity, I wonder what would be the pH level of the acid in a pitcher plant? I also wonder if it makes a difference if you stir it? Must be a somewhat high level. Pure water is at 7 and then oven cleaner is around 13.5. Then you have Lemon juice around 2-pH level. The lower the number higher the acid content. I am guessing around 3 to 4-pH level for a pitcher plant (Nep or Sarr). I would need a pH stick to find out. You figure is breaks down soft tissue insects so it would have to be somewhat high, right?
