💡 Drying Cannabis Isn’t About “Low & Slow” — It’s About Physics
The popular 60°F / 60% RH method sounds good, but fails under scientific scrutiny. Sharkmouse Farms challenges this tradition using thermodynamics, vapor pressure theory, and biological evidence. Surface water evaporates quickly, but internal plant moisture lags behind. If drying is too cold or slow, you trap moisture inside dense buds — a perfect setup for botrytis (bud rot) and mold outbreaks.
Under Fick’s Law, moisture wants to escape from high-concentration zones (inside buds) to low-concentration ones (the room). But if the environment doesn’t support that exchange (low vapor pressure), the inner bud stays wet while the outside dries — locking in problems.

Phase | Temp (°C/°F) | RH (%) | Vapor Pressure (kPa) | Time | Key Action |
---|---|---|---|---|---|
1 | 22.2 °C / 72 °F | 55 | 1.20 | 48 hrs | Remove surface moisture (desorption starts) |
2 | 23.3 °C / 74 °F | 52 | 1.39 | 24 hrs | Promote inner moisture migration outward |
3 | 23.9 °C / 75 °F | 48 | 1.50 | 48 hrs | Achieve ideal internal RH (~60%), prevent mold |
🌱 Why the Sharkmouse “Step-Down Dry” Method Works
Instead of freezing your dry room and praying for the best, this method uses gradually increasing vapor pressure differentials to pull moisture outward at a controlled rate. It keeps the terpene profile intact, reduces microbial risk, and matches the flower’s internal moisture release rate.
✅ Key Goals of Step-Down Drying:
- Prevent surface-hardening that blocks internal evaporation
- Maintain chlorophyll degradation (critical for smooth flavor)
- Allow even moisture transfer across the plant
- Avoid terpene boil-off (which happens even at room temp over time)

🧪 Terpenes and Time: Why Faster Drying Matters
“Slow and cold” might feel safe, but it’s scientifically flawed. Studies (Ross & ElSohly, 1996) show terpenes degrade rapidly — with as much as 55% lost within the first 7 days. Temperature alone doesn’t preserve them; time and air exposure are bigger factors.
And it’s not just smell. Terpenes are pharmacologically active — meaning that limonene, myrcene, and pinene all contribute to the “entourage effect.” Preserving them means preserving potency and medical efficacy.

🌘 Darkness = Better Chlorophyll Breakdown
Another Sharkmouse nugget: drying in darkness boosts chlorophyll breakdown. Research by Okada et al. (1992) showed that plant material stored in darkness for 3+ days exhibited faster and more complete chlorophyll degradation. This translates to smoother smoke and less “green” flavor.
💡 Pro Tip: Harvest during the final dark cycle before lights-on. Chloroplasts are already depleted of energy and enzymes, leading to better curing potential and faster chlorophyll fade.

🪓 Trim Later, Not Now
Contrary to some methods, Sharkmouse suggests not trimming wet. Instead, dry branches whole and only buck and trim after drying is complete. Why?
✅ Benefits of Post-Dry Trimming:
- Less terpene loss from exposed trichomes
- Slower surface drying = better moisture balance
- Easier to handle once dry
📦 Post-Dry Storage and Cure Tips
Once you’ve followed the 3-phase drying process, it’s time to cure your flower:
- Trim and place buds into glass jars
- Use Boveda packs to maintain RH between 58–62%
- Burp jars daily for the first 7 days
- Store in cool, dark space
- After 3–4 weeks, long-term flavor and cannabinoid stability begins
🌱 Science Over Tradition
Sharkmouse’s drying process isn’t “new age” — it’s thermodynamically optimized. Every phase is backed by math, moisture studies, and proven kinetics from food preservation, herbal drying, and cannabis-specific research.
✅ Better drying means:
- Fewer mold risks
- Cleaner smoke
- Richer terpenes
- Faster turnaround (no 14-day torture sessions)
It’s time to upgrade from folklore to formulas.
