I took the rain caps off. I have 2 sensors that read exactly the same and a 3rd that is lower by 5%, but the temp is the same as the others. I know the 1 sensor is definitely lower then the other 2. I have them in a ziplock container, I wonder if it leaks a little because even my digital hydro isn't reading 75% yet after 2 days. I have never done the salt test before just used the boveda pack, but I just put a couple teaspoons of salt in a small container and wet it with some distilled water so its kind of slushy looking.
