Tools and Materials
Once your tools are gathered, you’re set to begin the extraction process.
Basic Equipment List
Here’s what you’ll need:
- Two food-grade buckets: One for mixing and one for catching filtered water.
- Bubble bags or mesh filter bags: Use graduated micron sizes for separation.
- Fresh-frozen buds or dried trim/flower: Your starting material.
- Ice: Keeps everything cold during extraction.
- Cold, filtered water: Essential for the process.
- Sturdy mixing tool: Helps agitate the mixture.
- Clean work surface: Keeps everything hygienic.
Optional Tools
While not necessary, these extras can make the process easier:
- Digital thermometer: Helps monitor water temperature.
- Drying screen or rack: Speeds up the drying process.
- Small scrapers or spatulas: Useful for collecting resin.
- Nitrile or latex gloves: Keeps your hands clean and prevents contamination.
- Clean towels or wipes: Handy for spills and cleanup.
- Loupe or magnifying lens: Great for inspecting trichomes.
Choosing the Right Bubble Bags
Bubble bags play a key role in separating materials. Coarse bags (higher micron sizes) remove stems and leaf fragments, mid-range bags capture lower-grade resin, and fine bags isolate the highest-quality trichomes.
When selecting bubble bags, consider:
- Durability: Bags should withstand repeated use.
- Mesh stability: Ensure the mesh holds up in cold water.
- Bucket compatibility: Match bag size to your buckets.
- Smooth drainage: Helps avoid clogs and speeds up the process.
A basic four-bag set works well for simple separation. If you want more precise grading, expand the range of micron sizes.
With your tools ready, it’s time to prepare your materials and start the extraction process.
Making Bubble Hash: Step by Step
Prep Work
Before you start, make sure your tools and materials are ready. Lay clean towels over your work surface and set up your buckets in a well-ventilated area with a temperature of 65–70°F (18–21°C). Freeze your cannabis material for at least 24 hours. Fill one bucket with 2–3 pounds of ice and enough water (35–40°F) to fully cover the material.
In the second bucket, stack your bubble bags in this order: the 220-micron (work bag) on top, followed by the 160-micron, 73-micron, and 25-micron bags at the bottom.
Mixing Process
Place your frozen cannabis material into the 220-micron work bag. Pour the ice-water mixture over it, ensuring the material is fully submerged but leaving about 4 inches of space at the top for stirring.
Use your mixing tool to stir gently:
- First 5 minutes: Slow, circular motions
- Next 10 minutes: Gradually increase the speed
- Final 5 minutes: Return to gentle stirring
Keep the water temperature below 40°F by adding more ice as needed. Avoid rough stirring, as it can break down plant material and contaminate the hash.
Filtering Steps
Once mixing is complete, let the solution settle for 2–3 minutes. Then, lift the 220-micron bag and allow it to drain fully. Gently shake the bag to help the water flow through and set it aside.
Repeat this process with the remaining bags:
- Lift each bag slowly and let it drain completely.
- Spray the bag gently with cold water to push the trichomes through the mesh.
- Use light pressure around the sides of the bag to encourage drainage.
Hash Collection and Drying
For each bag, follow these steps:
1. Initial Collection
Let the bag drain fully. Use the back of a clean spoon to press out any remaining water from the resin collected at the bottom.
2. Resin Gathering
Carefully scrape the resin paste off the mesh with a card or spatula. The resin’s color will vary from light tan to golden, depending on the micron size.
3. Drying Process
Break the collected hash into small 1/4-inch pieces and spread them out on parchment paper. Place them in a cool, dark, and ventilated area to dry for 2–7 days. Once dried, the hash should feel light and sandy. Always handle it with gloves to avoid contamination.

Problem Solving and Tips
After filtering your hash, address these common issues before moving on to drying and storage.
Common Problems
Low Yield Issues
The quality of your input material directly affects both yield and purity. As Hashtek explains:
"Making bubble hash is an extraction, not a magic process. It is impossible to take poor quality product and make something great with it".
Material Preparation Problems
For dry material, soak it for 30–120 minutes and break up any clumps. Fresh-frozen material requires only 1–5 minutes of soaking.
Water Quality Issues
Use reverse-osmosis or filtered water to eliminate chlorine and preserve flavor.
Once these factors are addressed, focus on controlling temperature and moisture for the best results.
Temperature and Mixing Guide
Keeping the extraction process cold is key to avoiding contamination. As Hashy Blog highlights:
"Washing the best hash generally means keeping your water and ambient temp as cold as you can get them. Cold water helps to separate the trichome heads from the plant material more efficiently".
Aim to maintain water temperatures between 32–34°F, and never let it rise above 40°F.
Tips for Maintaining Cold Temperatures
- Use pre-chilled, filtered water.
- Monitor water temperature regularly.
- Add ice as needed to keep it cold.
- Keep the room cool during the process.
Drying and Storage Methods
Drying and storing your hash properly is essential for preserving quality.
Drying Tips
Keep the drying area at approximately 55°F with humidity below 35%. Provide gentle airflow to help the hash dry evenly. Spread it out in a thin, even layer to ensure it dries uniformly until it feels light and sandy.
Storage Best Practices
- Use airtight containers like mason jars or C-vaults.
- Minimize headspace to reduce oxygen exposure.
- Let containers reach room temperature before opening to prevent condensation.
- Avoid silicone containers for long-term storage.
- Store in a cool, dark place to maintain potency and flavor.
Using and Storing Bubble Hash
Once your hash feels dry, light, and sandy, it’s crucial to store and handle it properly to maintain its quality. After ensuring it’s completely dried (see Drying and Storage Methods), follow these tips to keep it in top condition.
Storage Tips
For optimal storage, stick to the guidelines outlined in Storage Best Practices. Here are additional tips for handling and storing your bubble hash:
- Use airtight glass jars and keep them at 55°F with humidity levels below 35% RH.
