Bubble Hash is simply trichome heads separated from the rest of the plant material using ice water and mild agitation.

Key Inputs – What Matters

Use either frozen trim or small buds. Utilizing fresh-frozen material will yield brighter terpenes; utilizing cured material will produce a deeper “hashy” note. Maintain the temperature of the water between 0–4°C throughout the entire process (add ice frequently); do not shred the leaves – your goal is to remove the trichomes from the leaves and not turn them into a liquid.

Guide to Microns – What Each Bag Is Used For

Micron Bag Role / what to expect
220 µm (work) Catches large debris; resin passes through
160–120 µm Sandy; Good to Excellent
90 µm Highly Successful; Clean heads; Nice melt
73–70 µm Another Prime Grade with Strong Flavor
45 µm Mixed Cut; Great for Edibles or Pressable Rosin
25 µm Fine Material; Save for Cooking or Blending

Step-by-Step Process

Preparation & Freezing. Place the plant material on a tray and freeze completely; if possible, chill your buckets, bags, and water. Layer your bags from the smallest micron at the bottom to the largest micron (220 µm work bag) at the top in a clean bucket.

Washing. In a separate bucket (or small washing machine), place ice → plant material → ice → cold water until you achieve a thick slush. Gently stir the mixture for 5–8 minutes; cease stirring when the water begins to turn green. Allow the resin to settle for 2–3 minutes.

Draining. Carefully pour the mixture through your bag stack. Slowly raise each bag allowing it to drain; once drained, rinse the resin with ice-cold water to remove any microcontaminants.

Collection. Using a spoon or card, carefully lift the patty from each bag and transfer it to parchment paper. Label your bags by micron – 90 and 73 are generally the top choices; 45/25 may also be used.

Drying (Important). Freeze drying (18–36 hours) is preferred, however, if you do not have a freeze dryer, you may microplane or crumble the patties into loose granules while they are still cold and then dry them in a cool environment (15–20°C, 35–45% RH) for 5–7 days with minimal airflow. Damp hash may form.

Curing & Storage. After the hash is completely dry, place it in a loose jar for several days, and then seal it and keep it in a cold, dark area away from direct sunlight.

How to make bubble hash easy: Working-Pro Tips that Save Batches

  • Perform multiple short washing cycles versus one single, longer washing cycle – performing 2 or 3 gentle pulling cycles and combining like micron grades will help reduce loss of trichomes during washing.
  • If the color of the hash begins to trend toward green, you are either agitating too aggressively or the water is too warm; add ice, reduce the length of the next wash cycle, and rinse more.
  • Wet or clumpy after a few days: did not dry completely. Re-granulate finer, extend dry time, lower humidity.
  • Bad taste: over-agitated the plant material or poor rinsing. Be gentler, use colder water, rinse more.
  • Terps Don’t Melt Well: Old/Oxidized Input or Incorrect Cut. Mix 90/73 Pulls; Reserve 45/25 for Edibles.

How to Make Bubblegum Hash

This is essentially about the genetic makeup of the plant. Utilize a variety of cannabis known as Bubble Gum or other sweet, fruity varieties, follow the same process described above, however, be extremely careful to control both the temperature and agitation so you do not damage the light, volatile terpenes.

How to Make Bubble Hash Oil

You have two solventless routes depending upon which route you wish to take. To produce dabs, press the dried bubble into rosin at a low temperature (approximately 80–95 °C / 175–200 °F) under moderate pressure.

To produce edible or tincture oil, decarb the dry hash (approximately 105–115 °C / 221–240 °F for 30–40 minutes), and then infuse into warm MCT or olive oil (65–80 °C for 1–2 hours) and strain if desired.

If you want to know how to easily make bubble hash on your first attempt, start with clean materials and do not rush the drying process – this is where most newbies fall down.
