The Art of Making Bubble Hash: Tips and Tricks for Success

What is Bubble Hash and How Does it Work?

Bubble hash is a type of cannabis concentrate made through a process of ice water extraction. It utilizes ice-cold water and agitation to separate trichome heads from the plant material, resulting in a highly potent and flavorful concentrate. The name “bubble hash” comes from the bubbles that form during the extraction process.

To make bubble hash, cannabis plant material is mixed with ice and water in a bucket or extraction vessel. The mixture is then agitated, allowing the trichomes to detach from the plant material and sink to the bottom. The water is carefully drained, and the remaining trichomes are collected, dried, and cured to create the final bubble hash product.

Choosing the Right Strain for Making Bubble Hash

When it comes to making bubble hash, not all cannabis strains are created equal. Some strains are more resinous and produce higher yields of trichomes, which are essential for making high-quality bubble hash. Here are some considerations when choosing a strain:

1. Resin Content:

Look for strains known for their high resin production. Indica-dominant strains and strains with dense, sticky buds tend to have more resinous trichomes.

2. Trichome Visibility:

Inspect the buds under magnification to assess the trichome coverage. Strains with abundant and prominent trichomes are ideal for making bubble hash.

3. Terpene Profile:

Consider the aroma and flavor profile of the strain. Terpenes contribute to the overall sensory experience of bubble hash, so choose strains with desirable terpene profiles.

It’s worth noting that personal preference plays a significant role in strain selection. Experimenting with different strains will help you discover the flavors and effects you enjoy most in bubble hash.

The Tools and Materials You’ll Need for Making Bubble Hash

Before diving into the process of making bubble hash, it’s essential to gather the necessary tools and materials. Here’s a list of what you’ll need:

1. Cannabis:

Choose high-quality cannabis flower or trim from the strain you’ve selected for making bubble hash. Ensure the plant material is clean, free from mold, and properly dried.

2. Ice:

Ice is a crucial component of the bubble hash extraction process. Use ice cubes made from filtered water to ensure purity and prevent any unwanted impurities from ending up in your concentrate.

3. Water:

Use clean, cold water for the extraction process. Filtered water or distilled water is recommended to avoid any contaminants that could affect the quality of your bubble hash.

4. Extraction Bags:

Extraction bags, also known as bubble bags, are specialized mesh bags with different micron sizes that allow you to separate the trichomes from the plant material. Typically, a set of bags with various micron sizes, such as 220, 160, 73, and 25, is used for the extraction process.

5. Extraction Vessel:

An extraction vessel, such as a bucket or a large container, is needed to hold the cannabis, ice, and water during the extraction process. Choose a vessel that is sturdy, easy to clean, and large enough to accommodate the amount of plant material you’ll be using.

6. Agitation Tool:

To agitate the mixture of cannabis, ice, and water, you’ll need an agitation tool. This can be a wooden spoon, a paint mixer attachment for a power drill, or a specialized bubble hash washing machine.

7. Drying Screens or Trays:

Once the extraction process is complete, you’ll need drying screens or trays to collect the wet bubble hash and allow it to dry properly. Stainless steel or food-grade drying screens are commonly used for this purpose.

Step-by-Step Guide to Making Bubble Hash

Now that you have your tools and materials ready, let’s dive into the step-by-step process of making bubble hash:

Step 1: Preparation

Start by placing your extraction bags in the extraction vessel, stacking them from largest to smallest micron size. The smallest micron bag should be placed inside the largest bag. This arrangement allows for progressive filtration during the extraction process.

Step 2: Adding Cannabis, Ice, and Water

Add your cannabis material, previously broken down into smaller pieces, to the extraction bags in the vessel. Add ice cubes on top of the cannabis, followed by enough water to cover the plant material.

Step 3: Agitation

Use your chosen agitation tool to gently stir and agitate the mixture. The goal is to separate the trichomes from the plant material by agitating the ice-cold water and cannabis. Agitate for about 15 to 20 minutes, being careful not to create excessive turbulence.

Step 4: Collecting the Extract

After agitating the mixture, allow it to settle for a few minutes to let the trichomes sink to the bottom. Carefully lift the extraction bags out of the vessel, one by one, starting from the largest micron size. Drain the excess water, and collect the extracted material from each bag. The smallest micron bag will contain the highest quality and purest trichomes.

Step 5: Drying and Curing

Transfer the collected bubble hash onto drying screens or trays. Gently spread it out in a thin layer to allow for proper airflow and drying. Place the screens or trays in a cool, dark, and well-ventilated area. Allow the bubble hash to dry for several days, periodically flipping and mixing it to ensure even drying. Once dry, the bubble hash can be cured in airtight containers for improved flavor and texture.

How to Dry and Cure Your Bubble Hash

Drying and curing your bubble hash is an important step to achieve the desired flavor, potency, and texture. Here are some tips for drying and curing your bubble hash:

1. Drying:

Transfer the wet bubble hash onto drying screens or trays in a single layer. Place the screens or trays in a cool, dark, and well-ventilated area with low humidity. Avoid direct exposure to light and heat, as they can degrade the quality of the concentrate. Allow the bubble hash to dry for several days, flipping and mixing it occasionally to ensure even drying. The hash is ready for the next step when it breaks cleanly without bending or sticking.

2. Curing:

After drying, the bubble hash can be cured to enhance its flavor, aroma, and smoothness. Transfer the dried bubble hash into airtight containers, suchas glass jars, and seal them tightly. Store the jars in a cool, dark place with stable temperature and humidity. During the curing process, the flavors and terpenes of the bubble hash will develop further, resulting in a more enjoyable experience. Allow the bubble hash to cure for at least a week, but longer durations of several weeks to a few months can yield even better results.

Remember to check on the bubble hash periodically during the curing process, opening the jars briefly to release any excess moisture and allow fresh air circulation. This helps prevent mold and ensures optimal curing conditions.

Troubleshooting Common Problems When Making Bubble Hash

While making bubble hash can be a rewarding process, it’s important to be aware of potential issues and how to address them. Here are some common problems that may arise and troubleshooting tips:

1. Low Trichome Yield:

If you’re not getting the desired yield of trichomes, it could be due to factors such as using low-quality plant material, improper agitation, or insufficient resin production in the chosen strain. To improve yield, consider using higher-quality plant material with more resinous trichomes, optimizing agitation techniques, and experimenting with different strains known for their resin production.

2. Contaminants in the Extract:

If you notice unwanted contaminants in your bubble hash, such as plant material or debris, it may be due to improper agitation or inadequate filtration. Ensure that your agitation is gentle and controlled to minimize the chances of plant material breaking apart. Additionally, consider using finer micron extraction bags to enhance filtration and prevent contaminants from entering the final product.

3. Mold or Mildew Formation:

Mold or mildew can develop if the bubble hash isn’t dried and cured properly. To prevent mold growth, ensure that the drying and curing environment has low humidity, good air circulation, and controlled temperature. If mold is detected, discard the affected portions immediately to avoid contamination.

4. Harsh or Chlorophyll Taste:

If your bubble hash has a harsh or chlorophyll taste, it could be an indication of insufficient drying or improper curing. Make sure the bubble hash is thoroughly dried before curing to remove excess moisture. During the curing process, proper airflow and controlled humidity levels will help eliminate chlorophyll flavors and allow the desired flavors to develop.


Making bubble hash is an art that requires patience, attention to detail, and a commitment to quality. By understanding the process, selecting the right strain, using proper equipment, and following best practices for drying and curing, you can create high-quality bubble hash with exceptional flavor and potency. Remember to prioritize safety throughout the process and enjoy the fruits of your labor responsibly.

Happy bubble hash making!
