As smokie mentioned, I think it would be a good idea to dry, cure, then vacuum seal it and then store it in the fridge or even freezer. I once read that you can store them in the freezer without any bad effects. Look at food for instance, we can store it in the freezer only to thaw it at a later date without any ill effects, unless you have frozen beef in there for over a year. I'd advise not to eat frozen beef that's beef frozen that long lol. You could probably vacuum seal it before it's dried and then freeze it, and it would probably stay fairly fresh. Once the item becomes frozen, you are basically stopping any aging process, degradation process, stopping the break down of organic material, etc. etc. You are basically stopping time. If it works with meat then it should work with buds. For an item to degrade it needs several things, acid, time, temperature, oxygen, and moisture. By vacuum sealing you are cutting off the oxygen to it, by freezing it you are cutting off the moisture and you are cutting off the temperature, and ultimately slowing down the time.
I would try it and see what happens, but I would dry, cure, vacuum seal then freeze. Another thing to keep in mind is that when you freeze something that still has moisture in it you are creating ice crystals inside the item that is frozen. By creating these ice crystals you will puncture holes in the cells inside the item. I think that if you are puncturing holes in the cells of the bud it would cause damage. Also, lol, by taking out the moisture of something you can prolong the time it's viable just like how jerky is dehydrated. Can't grow bacteria without moisture.
Sorry for the rambling but it's something I have been thinking about myself.
