Hanging and drying is a cure. Using jars and newspapers is also a cure. Once your bud is dry you can put it in a jar or zip loc bag and freeze or refrigerate it. I kept a couple of ounces in the fridge for over a year one time. I'd forgotten I had it. Lit some up - good as the day it finished drying. For those that are anal you can pump nitrogen in to replace the oxygen to keep the oils in the bud from oxidizing. I have a hard time keeping bud that long.
