Yes works great with a digital hygrometer. Just dont put it in the cup...LOL
Oh and make sure to read the hygrometer before you open the ziplock bag or you will need to wait another & hours...I am sure that was common sense but anyway..
Room temp does not make a difference....well unless its like 100 plus degrees or something.
