    Well, I forgot, its a half cup of salt with a little bit of water to make the salt the consistency of wet sand but what are the numbers and the exact measurments to recalibrate to see how far off my hygrometer is? Thanks in advance

    I dont remember for sure. Its like 1/4th cup of water to 2/3rds cup of salt. Wait 8-12 hours. It should read at 75%. Ive read on a few sites you dont have to use that much salt. It just says u need more salt then water.

    Google it or search BYC.I use 1/2 cup salt in cup add enough water to make it like wet sand
    .Put cup in 1 gal Zip lock along with Hygrometer .Seal and set aside in a way that you can read without opening for 7 to 12 hours .Reading should be 75 RH..Hygrometers generally have no way to adjust.So if its off over 10 off ( I get another ) less than I just allow for it...cva34
