Just like everything else in the world. The buds lose there taste, color, THC, and texture. Light, heat, moisture are no nos... Place them in a cool dark place with nothing touching them and a small fan keeping air moving around the buds, not directely on them. Dry till the stem has a snap to it thin place in jars. Once in jars you need to open them every 5-6 hours and gently remove them thin wipe away moisture and replace them.
