Why Storage Matters
You invested in premium cannabis — do not let improper storage ruin it. Exposure to light, air, heat, and moisture can degrade cannabinoids and terpenes, reducing both potency and flavor.
According to research cited by Leafly, THC can degrade into CBN (a less desirable cannabinoid) when exposed to light and heat over time.
The Four Enemies of Cannabis
1. Light
UV rays break down cannabinoids rapidly. A study published in the Journal of Pharmacy and Pharmacology found that light is the single greatest factor in cannabinoid degradation.
2. Air
Oxygen oxidizes THC and terpenes. Too much air exposure leads to harsh, flavorless cannabis.
3. Heat
Temperatures above 77F (25C) can dry out cannabis and encourage mold growth. The sweet spot is 60-70F.
4. Moisture
Too much moisture breeds mold. Too little dries out trichomes. Ideal relative humidity is 55-62%.
Best Storage Practices
- Use glass jars — Mason jars with airtight seals are ideal
- Keep it dark — Store in a cabinet or drawer, away from windows
- Maintain cool temperatures — Room temperature or slightly below
- Use humidity packs — Boveda or Integra Boost packs maintain perfect humidity
- Do not use plastic bags — Static can pull trichomes off the flower
- Do not refrigerate or freeze — The cold makes trichomes brittle
Storage Timeline
| Method | Freshness Duration |
|---|---|
| Open bag | 1-2 weeks |
| Sealed plastic | 2-4 weeks |
| Glass jar (dark) | 3-6 months |
| Glass jar + humidity pack | 6-12 months |
Signs Your Cannabis Has Gone Bad
- Crumbles to dust when touched (too dry)
- Smells musty or like hay (mold or degradation)
- No aroma at all (terpenes gone)
- Harsh, unpleasant smoke
Pro Tips
- Label your jars with strain name and date
- Do not grind until ready to use — Ground cannabis degrades faster
- Separate strains to preserve individual terpene profiles
- Check weekly for any signs of mold
