BCK beat me to it, but yeah AC water is ok. Water from a dehumidifier also works. THe reason I mentioned it is I lost my former collection which was in an undrained terrarium.....was good for over a decade then it went to hades in a matter of a week. Since then I have stuck to growing protocol where I can regularly flush out accumulated salts. I was religious in my use of distilled water too but after time things just seem to go bad no matter ho careful you are. Sarracenia seem a little more forgiving than Drosera.
