Yes, good thing to point out peace grow. Also there are moisture absorbing strips, and also oxygen absorbing strips. Both used together can help extend product life a long ways, especially if it is kept in a freezer or fridge. Tinted glass in a few baggies with oxygen absorbing and moisture absorbing strips in them is the best way to store stuff if you plan to get into it a lot. If you have something and know you wont use it for a few months I would vac seal it and freeze it probably.
