I do that to, jar the buds "to early" sometimes, depending on the season here in Sweden. We get some really low humidity times here. I jar the buds with a humidity meter and open the jars when it go over 75%, wich will happen real fast if the buds have a lot of moist in them. The i open and close the jars only by going after the reading on my meter. Its so easy one just cant fail.
Only way to go wrong is to let your buds dry out to much, wich is really hard if you ask me.
