I use a battery-powered vac pump on mason jars if I want to keep the smell hidden between sessions and only bring out the AC-powered vac pump for long-term storage in the mason jars.
I only have and use a rechargeable vacuum sealer.
Just opened a small mason jar I vac sealed long ago with some CBD samples.
I always DATE my 62% Bovida pacs.
The date on the pacs was October 2022.
The Bovida pacs were still soft, meaning they are still GOOD.
*Since the legalization, I don’t vac seal much anymore as don’t feel the need for long term storage, but it’s proof to me that it’s a great solution, when needed.
