I have an eigth that is in a air tight bag in a hiding spot in my room. They will be okay there for a week or two right?
Yes, as long as heat and moisture doesn't get to them they should be fine. I try not to hold onto a bag for a long time, the longest I ever had a bag for was a week and they were still good.
They'll easily last a month or two in a tight zip bag as long as they're dried. Just keep out of light/heat/moisture. For longer storage, there are many methods posted on shroomery.org about storing in honey/co2/capsules. Basically, once the mushies are absolutely dry, you need to keep as much air away from them as possible to prevent oxidation. Cheers
