How to make your own CBD hash at home: The complete guide to extraction techniques

For dry sifting

• Sieves of different microns (150μ, 120μ, 90μ, 73μ)
• Wooden frames for the sieves
• Rigid plastic card
• Clean, cool work surface

For rosin

• Hydraulic press or iron
• High-quality parchment paper
• Pressing bags (25-37 microns)
• Collection tool (dabber)

Method 1: Bubble Hash (Ice-o-lator)

Detailed steps

1. Preparation: Place your CBD flowers in the freezer for 24 hours
2. Setup: Arrange the bags in descending order of microns
3. Extraction:
   • Add ice + flowers + cold water
   • Stir gently for 15-20 minutes
   • Leave to rest for 10 minutes
4. Filtration: Lift each bag gradually
5. Collection: Collect the resin from each sieve
6. Drying: 24-48 hours on sieves, in a dry environment

Qualitygrades

• 220μ bag: Plant material (compost)
• 160μ bag: Culinary quality
• 120μ bag: Good quality
• 73μ bag: Very high quality (full melt)
• 45μ bag: Premium quality
• 25μ bag: Ultra premium (rare)

Method 2: Dry Sift

Dry sifting technique

• Preparation: Well-dried flowers, cool environment
• First sieve (150μ): Remove plant debris
• Second sieve (120μ): Collect medium-sized trichomes
• Third sieve (90μ): Refine the selection
• Final sieve (73μ): Obtain the purest resin

Tips for dry sifting

• Work in a cool environment (15-18°C)
• Use light, steady movements
• Never force the passage
• Store each grade separately

Method 3: Rosin Press

Pressing technique

1. Preparation: Slightly moistened flowers (55-62% RH)
2. Temperature: 80-120°C depending on the desired texture
3. Pressure:
   • Flowers: 600-1000 PSI
   • Hash: 400-800 PSI
4. Duration: 30 seconds to 2 minutes
5. Collection: Immediate cold recovery

Settings depending on desired result

• Sappy texture: High temperature (110-120°C)
• Budder texture: Medium temperature (90-100°C)
• Stable texture: Low temperature (80-90°C)
• Method 4: Traditional charas

Ancient manual technique

1. Selection: Fresh, resinous flowers
2. Rubbing: Between the palms for 10-15 minutes
3. Formation: Roll the accumulated resin into a ball
4. Refinement: Press and reshape several times
5. Maturation: Allow the aromas to develop

Storage and preservation

Optimal conditions

• Temperature: 4-10°C (refrigerator)
• Humidity: 55-65% RH
• Containers: Airtight glass or parchment paper
• Duration: 6-12 months depending on the method

Avoid at all costs

• Exposure to direct light
• High temperatures
• Excessive humidity
• Plastic containers (long term)

Expected yields

By extraction method

Bubble hash: 15-25% of initial weight

• Dry sift: 10-20% of initial weight
• Rosin: 15-30% of initial weight
• Charas: 5-15% of initial weight

Factors influencing yield

• Quality of the starting flowers
• Trichome richness
• Mastered extraction technique
• Environmental conditions

Quality testing

• Evaluation criteria
• Colour: Golden blonde to light brown
• Texture: Supple, malleable at room temperature
• Aroma: Preserved terpenes, intense fragrance
• Solubility: Melts completely (full melt)

Bubble test

High-quality hash should melt without leaving any black residue or significant ash.

Use and dosage

Methods of consumption

• Vaporisation: 160-180°C to preserve terpenes
• Dabbing: Technique for pure concentrates
• Infusion: In fatty substances for culinary use
• Combustion: Mixed with neutral herbs

Recommended dosage

• Beginners: 0.05-0.1g
• Regular users: 0.1-0.3g
• Experienced users: 0.3-0.5g

Legal aspects and safety

• Personal production: Legal grey area
• THC < 0.3% mandatory
• Sale prohibited without licence

Personal use tolerated

• Safety precautions
