How to Make the Best Bubble Hash at Home: A Step-by-Step Guide
Key Takeaways
✔ Bubble hash is a solventless concentrate made using ice water and agitation to separate trichomes from cannabis.
✔ High-quality bubble hash is potent, clean, and full of terpenes for a smooth smoking or dabbing experience.
✔ The process requires a few key tools, including bubble bags, ice, and a stirring tool.
✔ Proper drying and storage are essential to preserve potency and flavor.
✔ The best bubble hash melts when heated, indicating high trichome purity.
Introduction
Bubble hash is one of the purest and most potent cannabis concentrates you can make at home. Unlike chemical extraction methods that use solvents like butane or ethanol, bubble hash is made using only ice, water, and agitation to separate trichomes from cannabis buds or trim.
This solventless method preserves the natural cannabinoids and terpenes, giving you a full-spectrum, flavorful hash that can be smoked, vaped, or pressed into rosin.

What Is Bubble Hash?
Bubble hash is a concentrated form of cannabis made by using ice water and fine mesh filters (called bubble bags) to separate trichomes from plant material. The process gently agitates cannabis in cold water, causing the trichomes to break off and collect in different micron-sized mesh screens.
✔ The term “bubble hash” comes from the fact that high-quality hash “bubbles” when heated.
✔ Bubble hash is rated on a star scale (1-6 stars), with 5-6 star hash being the highest quality and full-melt.
✔ It is completely solvent-free, making it a healthier alternative to chemically extracted concentrates.
💡 Key Tip: The purer the bubble hash, the lighter in color and softer in texture it will be.
Why Make Bubble Hash?
Bubble hash is one of the best ways to extract trichomes while maintaining the natural profile of the plant. Here’s why many growers and hash makers love it:
✔ No solvents – Uses only ice, water, and agitation, making it safer than BHO or ethanol extraction.
✔ Preserves terpenes – Full-spectrum hash retains more flavor and effects.
✔ Highly potent – Concentrates only the trichome heads, where THC and cannabinoids are stored.
✔ Great use for trim – Turn leftover sugar leaves and popcorn buds into high-quality hash instead of wasting them.
✔ Versatile – Can be smoked, vaped, dabbed, or pressed into rosin.
What You Need to Make Bubble Hash
Essential Equipment:
✔ Bubble bags (also called hash bags) – A set of micron-filter bags (220μ, 160μ, 120μ, 73μ, 45μ, 25μ)
✔ Two 5-gallon buckets – One for washing and one for filtration
✔ A large wooden spoon, paddle, or drill mixer – To stir the mixture
✔ A spray bottle with cold water – Helps collect hash from the bags
✔ A drying screen or parchment paper – For drying the hash
Ingredients:
✔ Fresh frozen or dried cannabis (trim or buds)
✔ Lots of ice – To keep the water ice cold (essential for proper trichome separation)
✔ Cold, filtered water – Helps prevent contamination and improves trichome separation
💡 Key Tip: For higher-quality hash, always use high-grade, resinous cannabis.
Step-by-Step Guide to Making Bubble Hash
Step 1: Set Up Your Bubble Bags
1️⃣ Stack the bubble bags inside the 5-gallon bucket, starting with the smallest micron filter at the bottom (25μ) and working up to the largest (220μ) at the top.
2️⃣ Place the second empty bucket nearby to collect hash later.
Step 2: Add Cannabis, Ice, and Water
1️⃣ Fill the top bucket (220μ) with cannabis (fresh frozen or dried, broken into small pieces).
2️⃣ Add enough ice to completely cover the cannabis.
3️⃣ Pour in cold water until everything is fully submerged.
💡 Key Tip: The colder the water, the easier trichomes are to break off without contamination of plant material.
Step 3: Agitate the Mixture
1️⃣ Use a wooden spoon or drill mixer to gently stir the cannabis and ice water for 10-15 minutes.
2️⃣ Let the mixture sit for 5-10 minutes to allow trichomes to settle.
Step 4: Filter and Collect the Hash
1️⃣ Lift the first (220μ) bag—this contains mostly plant material (discard or rewash).
2️⃣ Repeat this process for each bag, carefully collecting the hash from the finer micron filters (73μ, 45μ, 25μ).
3️⃣ Use a spray bottle to wash down the sides of the bags, helping hash collect at the bottom.
4️⃣ Scoop the hash onto a drying screen or parchment paper.
💡 Key Tip: The best quality hash comes from the 73μ and 45μ bags, which capture the most trichome heads.
How to Dry and Store Your Bubble Hash
✔ Press out excess water using a clean paper towel or pressing screen.
✔ Let hash dry for at least 24-48 hours in a cool, dark place.
✔ Avoid direct heat or sunlight, which can degrade cannabinoids and terpenes.
✔ Store in an airtight glass jar or freeze for long-term preservation.
💡 Key Tip: If hash is dried too fast, it can trap moisture and grow mold. Always dry slowly and evenly.
Tips for Getting the Best Quality Bubble Hash
✔ Use high-quality, resin-rich cannabis for the best yields.
✔ Keep water ice cold throughout the process.
✔ Stir gently—aggressive agitation will pull unwanted plant material into the hash.
✔ Collect hash from finer micron bags (73μ & 45μ) for the purest product.
✔ Dry hash properly before storing or pressing into rosin.
FAQ
Q: Can I use fresh frozen cannabis for bubble hash?
A: Yes! Fresh frozen cannabis preserves terpenes better than dried material.
Q: How do I know if my bubble hash is high quality?
A: High-quality hash is light in color, melts cleanly, and bubbles when heated.
Q: Can I press bubble hash into rosin?
A: Absolutely! High-quality bubble hash (5-6 star) makes excellent rosin.
Conclusion
Bubble hash is one of the best solventless cannabis concentrates, providing pure, potent, and flavorful results when made correctly.
✔ Use high-quality cannabis
✔ Follow the proper washing, filtering, and drying process
✔ Enjoy solvent-free, full-spectrum hash
