Here's the skinny on freezing~ After you have dryed and Cured your buds you can put it safely in a airtight container, normally a jar with a rubber seal. If you put it in a rubbermaid container or glad seal/plastic it has been said that it can taste like plastic after awhile. You can put it in a freezer for a long period of time but if it is not airtight you will be in troubles and also I have heard that the outside of the bud gets a light freezer burn.
I use a small fridge that holds about 40 jars, I keep temp between 40-50 degrees. I hold them there for up to a year or April 20 .
