However, even in deep freeze THC deteriorates, at nearly 4% a year. In deep freeze (below 0°F) deterioration slows further. At refrigerator temperatures THC deteriorates at the rate of about 5.4% a year. A freezer is best for long-term storage; a refrigerator is good for protecting terpenes in the short term.
I have pot that is 2 and 3 years old and it's like new. I use 1/2 gallon Ball jars and I vacuum seal them.
In the past, I have used the same jars without vacuum sealing and the vacuum sealer definitely helps a lot.

I heard freezer is bad. Fridge is better. Something about freezer fracturing chlorophyll cells. Not 100% sure on that but, somehow recall hearing that.

long term storage?
keep the buds in sealed bags or jars in the Freezer
You guys got the vacuum seal part right, but vacuum means no air.
I've got 3 year old stuff that you would not believe. It gets stored in a cool dark place too.
