I have buds that have been curing for 2 months in mason jars and they are somewhat dry...Yesterday I took a few small leaves off of a plant in my yard and threw them on the the top of the buds (after opening the jars for the first time in months)...
Throw a couple of orange peels in your mason jar for about 2 days. You can also throw it in your bathroom and turn on the shower steaming hot for about 2-4 minutes, enjoy your now non-crispy buds
I have used the orange peel method before, works wonders and leaves your bud with a nice citrus note. I tear the peals into small, quarter sized pieces and mix it through out the bud and put it back in the jars. I always wash the oranges really well before I peal them to make sure I am not introducing any wierd fungus or any other type of spore into the jars. seal them up and burp them once a day.
