Good report.
I have kept bud tightly packed in mason jars for up to 3 years and it was actually better than when I put it up. (I am smoking a blooberry/haze from two years ago right now and it is awesome.) Never removed the air, though. Since air and light are what diminish THC, I packed them kinda tight and kept it in the dark. Nothing too warm. I will open up the jars and remove contents for about five minutes, every six months or so. It helps the cure and makes it real smoooth
Years ago, I used to have these Jamaican bibles. Kept some in the freezer for years and it was always good to go.
Keeping the air and light away is the key.
