Answer
Bubble hash is cannabis resin separated with ice water and micron bags. Cold water makes trichome heads brittle. Ice and agitation knock them off the plant material. Mesh screens catch the heads by size. The result is a concentrated hash that ranges from sandy to sticky depending on strain and screen size.
Cheap Bubble Hash Bags and Screens
What you need
- 5-gallon food-grade bucket, two if possible
- Bubble bag set: 220, 190, 160, 120, 90, 73, 45, 25 micron
- 4-8 oz (110-225 g) dried cannabis trim or flower
- 2-4 lb (1-2 kg) ice
- Clean, cold water
- Wooden spoon or plastic paddle
- Glass or ceramic collection dish
- Drying screen or desiccant pack
Use dried material, not wet. Freeze trim for 24 hours before starting. Work in a room below 70 F (21 C).
Cannabis Bubble Hash Terpene Profile: What Shapes Flavor
Step 1: Layer the bags
Place bags inside a 5-gallon bucket from smallest micron (25) to largest (220). The 220 bag sits on top. Line a second bucket with the 25 bag or use it as a catch bucket.
Step 2: Add cannabis, ice, and water
Put 4-8 oz of frozen trim in the 220 bag. Add a 1:1 ratio of ice to water, enough to cover the plant material. Water should sit at 32-39 F (0-4 C). Add ice as needed during the wash.
Step 3: Agitate
Stir with a paddle for 10-15 minutes. Use slow, circular motions. Do not blend or drill. High speed breaks plant matter into the hash. Let the mix settle for 10-15 minutes.
Step 4: Drain and collect
Pull the bag set out of the bucket. Let water drain through each screen. Rinse the 220 bag with clean cold water. Remove each bag one at a time. Scoop the hash from the 73, 90, 120, and 160 micron screens with a spoon. Collect the 45 micron screen separately. The 25 micron screen holds the smallest heads and plant matter.
Place each grade on a 25 micron pressing screen over a towel. Press with a paper towel to remove water.
Step 5: Dry
Break hash into small pieces. Dry in a dark room at 60-70 F (15-21 C) and 45-55% humidity. Air-dry 24-72 hours. Hash is dry when it crumbles and does not feel cold or damp.
Step 6: Store
Store dried hash in an airtight glass jar. Keep it in a cool, dark place. Refrigerate for long storage. Label the jar with screen size and date.
Yield and grades
A 4-8 oz batch of trim yields about 5-15 grams of bubble hash. Flower yields more. The 73-160 micron range holds the best full-melt grade. Lower grades work for edibles or pressing.
Problems to avoid
- Warm water: keep ice in the mix.
- Over-agitation: stir, do not blend.
- Wet hash: dry until no moisture remains before sealing.
- Dirty bags: rinse with cold water, never soap.
