How to Make Bubble Hash<\/h2>\n\n\n\nChoosing the Right Strain <\/h3>\n\n\n\n![\"\"](\"https:\/\/mobiustrimmer.com\/en-ca\/wp-content\/uploads\/sites\/5\/2023\/05\/AdobeStock_462250224-1024x683.jpg\")
<\/figure>\n<\/div>\n\n\nWhen learning how to make bubble hash, understanding how important it is to choose the right cultivar is key. Keeping in mind that bubble hash is created from cannabis trichomes, the best strains for making high-quality bubble hash<\/a> are those that are the stickiest and most resinous. Contained inside these trichomes are all of the compounds found in cannabis, such as cannabinoids, terpenes, and flavonoids, that give each strain its unique profile. <\/p>\n\n\n\nCertain cannabis trichomes are better suited for making bubble hash than others, and while bubble hash can be created with any strain, the best strains are those that produce numerous capitate-stalked trichomes. These are trichomes that are visible to the naked eye, with a long stalk and bulbous head that resembles a mushroom. <\/p>\n\n\n\n
The best strains for making bubble hash have trichomes with glandular heads that are easily released during the washing process. Some strains contain a considerably strong connection between the head and stalk of the trichome, making it harder to release, while in others, the connection is too weak, and too much oil is released from the trichome head during production.<\/p>\n\n\n\n
Cultivars that contain plenty of trichomes and have a strong aroma and flavor profile are the best for producing bubble hash. Avoid strains that don\u2019t have a strong terpene profile.<\/p>\n\n\n\n
Essential Equipment for Making Bubble Hash<\/h3>\n\n\n\n
To produce the highest-quality bubble hash on a commercial scale, utilizing the right equipment is essential. The first step is to ensure you are harvesting your plants for maximum trichome retention. Once the flower is harvested at its peak, you can begin the process of bubble hash extraction.<\/p>\n\n\n

- Freezer to hold fresh frozen cannabis flower<\/li>\n\n\n\n
- Freeze Dryer for collected bubble hash<\/li>\n<\/ul>\n\n\n\n
For making bubble hash on a commercial scale, washing by hand is not a viable option. A hash washer is needed to help scale the process to make it efficient, profitable, and consistent for quality and time to market. Hash washers range in size and processing capacities with varying features. The Mobius M100 Hash Washing System<\/a> has advanced features like integrated cooling, dewatering technology, and automatic wash sequences. <\/p>\n\n\n\nQuality, Cleanliness, and Materials<\/h3>\n\n\n\n
When making bubble hash, cleanliness is extremely important and should be thoroughly attended to. Any dust, dirt, or foreign particles can easily become part of the final product if the equipment isn\u2019t routinely cleaned and cared for. While cleaning can be one of the more challenging parts of harvesting cannabis and producing concentrates, keeping your workspace tidy and ensuring each piece of equipment is regularly maintained can help warrant a high-quality end product free from potential contaminants. <\/p>\n\n\n\n
Every aspect of processing affects the final quality of the end product, and cleanliness, proper maintenance, and the plant material are no exception. Ensure your cannabis flower is free from debris, dust, and any excess materials. Keep the flower in sealed bags to maintain freshness, and store in a freezer, if available. Use filtered water for your washer, or water from a reverse osmosis system to create the cleanest washing environment for your bubble hash. <\/p>\n\n\n\n
How to Prepare Cannabis to Make Bubble Hash<\/h3>\n\n\n\n
Correctly preparing cannabis prior to making bubble hash is key for success in this category. While bubble hash can be made from freshly harvested and cured cannabis, it\u2019s commonly produced from fresh frozen flower. Some hash producers contend that fresh frozen flower contains higher terpene content and can produce larger yields. <\/p>\n\n\n
\n![\"\"](\"https:\/\/mobiustrimmer.com\/en-ca\/wp-content\/uploads\/sites\/5\/2023\/05\/Frozen-Blueberry-Muffin-8679_websize.jpeg\")
<\/figure>\n<\/div>\n\n\nIt\u2019s important to create an optimal environment when making bubble hash. While it requires proper planning, the effort put into designing the extraction space will make the entire process more efficient, and will ultimately lead to the most potent and profitable end products. With the right equipment<\/a> and workflow design, you can create an ideal environment for producing high-quality bubble hash. <\/p>\n\n\n\nSince bubble hash is a concentrate created using chilled water, a cold room is the best environment when considering your processing production for making bubble hash. An air-conditioned space will offer the best conditions for bubble hash extraction. Cold temperatures will help best preserve the delicate trichome heads. The colder the room and equipment used to handle the starting material and final product, the better. <\/p>\n\n\n\n
When setting up extraction equipment in the room, you\u2019ll want to keep the workflow in mind and set up the equipment accordingly. You should be able to move around the room freely, with equipment organized in a way that allows workers to streamline the entire process. For example, fresh flower can be frozen before washing and starting the extraction process, so consider configuring your processing space accordingly to follow the steps of production. This will ensure an ideal work environment.<\/p>\n\n\n\n
Making Bubble Hash<\/h3>\n\n\n\n
Making bubble hash is one of the easiest methods of creating a cannabis concentrate. When created in the right environment with the right strains, bubble hash can offer a profitable return for commercial operations. <\/p>\n\n\n\n
Follow our step-by-step guide on how to make bubble hash:<\/p>\n\n\n\n
01 Prepare for Your Wash<\/h4>\n\n\n\n![\"\"](\"https:\/\/mobiustrimmer.com\/en-ca\/wp-content\/uploads\/sites\/5\/2024\/02\/Hash-wash-image-1024x684.jpg\")
<\/figure>\n<\/div>\n\n\nCollect all of your materials, prep your equipment, and add your cannabis to your washer.<\/p>\n\n\n\n
02 Agitate the Cannabis and Water Mixture<\/h4>\n\n\n\n
The first step of making bubble hash involves mixing the cannabis and cold water in your hash washer. Once your washer is full of the cannabis, ice (if needed), and water mixture, let it soak for 30\u201340 minutes, which prepares for a clean separation of the trichome heads from the plant material. After the mixture has soaked, allow the washer to run for 5-10 minutes, depending on the agitation level of your system. Ensure gentle agitation for an optimized extraction.<\/p>\n\n\n\n
03 Filter the Mixture Through Your Screens<\/h4>\n\n\n\n![\"\"](\"https:\/\/mobiustrimmer.com\/en-ca\/wp-content\/uploads\/sites\/5\/2025\/02\/BB_Still_12-1024x576.jpg\")
<\/figure>\n\n\n\nAfter the mixture has gone through the agitation process, the next step is draining the mixture through the layered bubble bags<\/a> (starting with the smallest filter size on the bottom, working your way up to the largest size as the first micron bag). This allows the first bubble bags to collect any plant debris and large particles before getting to the high quality hash around the 73-120 micron range. Gently rinse, then scoop the bubble hash from the bags and place on a tray for the drying process.<\/p>\n\n\n\n04 Collect and Allow Bubble Hash to Dry<\/h4>\n\n\n\n
Freeze-drying bubble hash is recommended, but it can also be air-dried. <\/p>\n\n\n
\n![\"\"](\"https:\/\/mobiustrimmer.com\/en-ca\/wp-content\/uploads\/sites\/5\/2023\/05\/freeze-dried-ice-water-hash-rotated.jpeg\")
<\/figure>\n<\/div>\n\n\nIf air drying, drain the water and place the bubble hash on the smallest micron screen bag, then press out any remaining water and freeze in a regular freezer. Once frozen, break the hash over parchment paper. Creating as thin of a layer of bubble hash as possible will aid in the most effective drying. It should then be placed in a cold room (40\u201350\u00b0F) for approximately 5\u20137 days. <\/p>\n\n\n\n
If freeze drying, once bubble hash is frozen, it should be placed on trays for approximately 4\u20136 hours and then dried in a cold room for around 16\u201320 hours. <\/p>\n\n\n\n
Tips and Tricks for Making the Perfect Bubble Hash<\/h3>\n\n\n\n
While making bubble hash is a relatively simple process, there are a few things to keep in mind that can help you make the perfect batch. We\u2019ve created a general guideline of what to consider when making the highest-quality bubble hash. <\/p>\n\n\n\n![\"\"](\"https:\/\/mobiustrimmer.com\/en-ca\/wp-content\/uploads\/sites\/5\/2024\/01\/M100_multi-vessel-system-1024x683.jpg\")
<\/figure>\n\n\n\nTemperature Control<\/h4>\n\n\n\n
One of the biggest things to remember is the importance of temperature control with any cannabis product and process. While ice water is used to make bubble hash, you\u2019ll find the highest quality bubble hash is created when the entire process is completed as cold as possible. <\/p>\n\n\n\n
An air-conditioned room will offer the best conditions for creating quality bubble hash. Temperatures in the washroom can be set as low as 30\u201340\u00b0F, which can positively contribute to the quality of the final product. If you can make your bubble hash in a large, walk-in storage freezer (like those common in restaurants), that\u2019s an even better option. <\/p>\n\n\n\n
You might also consider insulating the bubble hash bucket or washer to ensure temperatures stay as cold as possible throughout the entire process. <\/p>\n\n\n\n
Proper Agitation<\/h4>\n\n\n\n
Properly agitating bubble hash is key. When washing cannabis by hand, the mixture should first be gently stirred in the top bag for around 5\u201315 minutes. This first step in agitation will remove a considerable amount of trichomes, which will allow them to begin the filtration process through subsequent bags. It\u2019s extremely important to keep in mind that stirring with too much force can break off trichomes, which will decrease the quality of the final product. Be gentle and start slow, as you can increase agitation as you go if necessary. <\/p>\n\n\n\n
After the top bag is removed, the agitation process should be repeated in the same way until you\u2019ve gone through all bags and the bubble hash is ready to be collected from the bucket or wash tub. Properly agitating the mixture in each bag is critical for producing the highest quality end product.<\/p>\n\n\n\n
Know When to Stop Agitating<\/h4>\n\n\n\n
Over-agitating your mixture is possible, and knowing when to stop agitating is key. The perfect window for agitating the cannabis and ice water mixture will be between 5\u201315 minutes. If the mixture is agitated longer, you risk removing too much of the plant material which can contaminate the bubble hash. You can always go back and repeat the agitation process, but too much agitation from the start can decrease the quality of the final product. <\/p>\n\n\n\n
Use the Correct Micron-Size Bubble Bags <\/h4>\n\n\n\n![\"8](\"https:\/\/mobiustrimmer.com\/en-ca\/wp-content\/uploads\/sites\/5\/2025\/02\/lock-top_boldtbags_mobius-1024x1024.jpg\")
<\/figure>\n<\/div>\n\n\nBubble wash bags are the most fundamental piece of equipment in making bubble hash. Bubble bags come in different micron sizes, and the different microns on the screens separate different sizes of trichomes with as little plant matter contamination as possible. When making bubble hash, the wash tub should be lined with various micron sizes for each step in the agitation process. <\/p>\n\n\n\n
Smaller micron-sized bags only allow smaller particles to pass through the bag, while larger microns allow larger particles to pass through. The best quality hash is collected by multiple filters, and bubble bag wash kits are commonly sold in 4-bag or 8-bag options. Bags are stacked inside of each other, with the smallest micron size on the bottom. <\/p>\n\n\n\n
If you\u2019re washing a cultivar for the first time, using an 8-bag kit is recommended. Doing so allows you to determine the best micron size for filtering that particular cultivar. <\/p>\n\n\n\n
Micron bag sizes typically range between 25-220, whether sold in a 4-bag or 8-bag kit. A 220-micron bag contains the larger filter and also holds the ice and plant material. A 160-micron bag helps remove any contaminants remaining from the 220 bag and creates a low-grade hash (1-2 stars). The 120-micron bags will produce a decent bubble hash (3-4 stars), however, the 90, 73, and 45-micron bags are widely considered superior for producing the highest quality bubble hash (5-6 stars). The 73-micron bag is widely referred to as the \u201cfull melt bag,\u201d as this is the size typically used for creating full melt bubble hash<\/a>.<\/p>\n\n\n\nLast Thoughts on How to Make Bubble Hash<\/h3>\n\n\n\n
