I put mine in a plastic freezer bag and inject CO2 from my wifes soda maker and then seal with the sealer I use for cultivation bags. And then the shrooms that I plan to use in the next few months are ground to a powder and put in "00" gel caps. These I put in a vitamin bottle with a silicon pack. I've given some of these frozen shrooms to people a year after harvest and they were still considered the best they had ever had. ------------------
