To keep buds fresh and delicious, simply store them in an airtight container.

I use small jam jars that have the red seal along the top of it. I keep my buds in there for months and they still stay fresh. Just open the jar every few days to check if no mold is forming. If you store the buds when they're too moist, then you risk mold.

If you want to add mositure back itno your buds, I used to slice up a raw potato and place a few slices in a baggy with the buds. They dryest buds became moist after about 6-8 hours. Avoid letting the potato of whatever touch the buds though.

Take care.
