Safely storing dried and cured herb

[Zeltar]

I have used special foil bags that you iron seal closed, no smell comes out and keeps the buds crispy n fresh

If you wish to use a pressurized container for storing your medicine, might I suggest a standard soda keg. These are routinely used in the home beer craft industry and can be obtained used for very little money. Make sure to check and replace any faulty o-rings, valves, etc. then do soap and water test under pressure to make sure it holds. The top is usually large enough to have easy access into the 'belly' of the container. Any gas could be used for pressurizing, but Nitrogen is fairly inert and usually available for home brewing enthusiasts. If you had a 'keg-o-rator' set up with several tap brews and then your false keg in the back, not only would it throw off OP, but would keep your med's nice and cool for as long as you need to store them.

Good luck!

that thing does look promising. CO2 would work better than nitrogen as long as it doesnt come in contact with the herbs.
I know there are ways to extract with CO2 but ive never seen it done.

CO2 would work if, as you suggested, plants do not have contact. CO2 can be pretty active over time and would degrade your stash. Nitrogen is much more inert.
