Ooops .... it is the other way around .... 1/2 cup salt and 1/4 cup water.
Another tip ... be sure the salty slurry does not touch the hygrometer. The cup of slurry is in the 1 gallon size zip lock bag, then put the hygrometer into the bag, but not in the slurry. Zip lock the bag closed.
Actually - it works either way. I've tried. Amazingly enough I get the same result.
