I grew these about 4 months ago. They've been sitting in my closet in an airtight container since then. They look ok, I just want to see if anyone can tell me if maybe they've gone bad.
If they have been 4 months in an airtight container in a closet and look ok they should be. Mushroom's store for quite some time. If you plan on storing them longer I would suggest adding a dessicant pack to your container. To keep them dry. Mushrooms suck moisture out of the air.
