The short version: air-dry your mushrooms on a wire rack with a fan until leathery (24–48h), then finish them in a sealed container over desiccant until they snap like a cracker. Done right, dried shrooms keep their potency for a year or more. Done wrong — heat, sunlight, moisture — psilocybin degrades fast.
Why drying matters
Fresh mushrooms are ~90% water and mold within days. Moldy mushrooms are dangerous — never eat them. "Cracker-dry" mushrooms stored properly are stable, easy to weigh accurately for dosing, and taste less… mushroomy.
Stage 1: air-dry (24–48 hours)
- Space mushrooms out on a wire rack or mesh so air reaches all sides.
- Point a fan near (not directly at) them, in a dark, dry room.
- They're ready for stage 2 when the outside feels dry and leathery but stems still bend.
Stage 2: desiccant finish (1–3 days)
- Put a layer of desiccant (silica gel packets, or DIY: oven-dried Epsom salt) in the bottom of an airtight container.
- Set a raised mesh above the desiccant, mushrooms on top — never touching the desiccant.
- Seal. Check daily. Done when a stem snaps instead of bending.
What NOT to do
- No ovens, no dehydrators above ~95°F — heat destroys psilocybin.
- No direct sunlight — UV degrades potency.
- Don't store half-dry. Any bend left in the stem = enough moisture to mold in a jar.
Storage
Airtight jar, desiccant packet, cool dark cupboard. Properly dried and stored, count on 12+ months at full strength.
