Long-term cannabis storage without loss of quality. Optimum conditions for years of storage.
Proper cannabis preservation preserves quality and potency for years:
Conservation basics:
Quality degradation factors:
- Light (UV radiation)
- Oxygen (oxidation)
- Moisture (mould/drying out)
- Temperature (chemical reactions)
- Time (natural degradation)
Cannabis shelf life:
- Optimal conditions: 2-4 years
- Average storage: 1-2 years
- Poor conditions: 6-12 months
- Extracts: Longer shelf life
- Edibles: Shorter shelf life
Optimal storage conditions:
Temperature:
- Ideal: 15-20°C
- Cooler = longer shelf life
- Avoid frost (<0°C)
- Minimise fluctuations
- Cellar temperatures often optimal
Humidity:
- Optimal: 55-62% RH
- Above 65%: Danger of mould
- Below 50%: Terpenes vaporise
- Use humidity packs
- Aim for constant values
Light protection:
- Complete darkness ideal
- UV radiation particularly harmful
- Brown/opaque containers
- Cool, dark rooms
- LED lighting for inspections
Oxygen minimisation:
- Airtight containers
- Vacuum sealing for long-term storage
- Nitrogen flushing
- Minimised air exposure
- Fast handling
Storage container:
Glass containers:
- Airtight Mason Jars
- UV protection (amber glass)
- Various sizes
- Easy to clean
- Neutral flavour

Freeze-drying (Advanced):
Freeze-drying advantages:
- Maximum shelf life (10+ years)
- Terpenes and cannabinoids preserved
- Mould risk eliminated
- Weight reduction
- Professional technique
Freeze-drying process:
- Flash-freeze at -40°C
- Vacuum sublimation
- Moisture removal (99%+)
- Specialised equipment needed
- Industrial application
Monitoring and maintenance:
Regular inspections:
- Monthly quality checks
- Mould detection
- Humidity level check
- Flavour assessment
- Visual inspection
Rotation system:
- FIFO (First In, First Out)
- Use oldest stock first
- Labelling with date
- Inventory management
- Quality tracking
Train-specific storage:
Indica vs. Sativa:
- Dense Indica: More risk of mould
- Airy Sativa: Less susceptible
- Adjust RH accordingly
