Here is a link to the website I bought my hygrometer from. http://incubatorwarehouse.com/incubator-thermometer-hygrometer.html I did the salt and water in a ziploc bag thing, and my hygrometer read 65%. What do I do? I left it in over night (12 hours) would this of messed it up? Does anyone have a link to where I can get a manual for this thing? Is this even a good one? Thankyou.
