Product review (1 stars): Raises the humidity inside jars but does not control it ...
Raises the humidity inside jars but does not control it... they are supposed to stay at 62% humidity and not go above. The humidity was at 52-59% before adding these to the jars, after they were put in the humidity went up to 68%. I bought these boost packets because they came in two days versus waiting an extra 4 or 5 days for the Boveda 62% packets. After using the both and watching the humidity levels inside each of the jars Boveta wins by a long shot!
