// Definition
Two methods of drying water hash after extraction. Air-drying allows hash to grease up and round naturally, hiding minor contaminants like capitate stalks within the greased surface. Freeze-drying preserves individual trichome structure but reveals contaminants as visible shadows of their former structure.
// From the Episode
Bubbleman noted air-dried hash is more photogenic because greasing hides impurities. Freeze-dried hash shows capitate stalks that are invisible in greased hash — they appear as 95% evaporated shadows. Both methods have nostalgic and practical value. Air-dried six-star hash develops a beautiful skin over weeks of curing.
