Thanks Copobo. I found some hygrometers at McGuckins that are about the size of a watch. they do temp, humidity, and 24 hour recording. $19.99 is pricy but they are small and fit in the cure bags well. I also found some double ziplock bags at Target that are the size of a large pillow case. They are clear blueish so you can see the humidity reading through the bag to know when to burp it. Ive never had a problem with plastic taste from curing in plastic containers.
