Inside the Bubble Hash Process with HPI Canna: A Deep Dive into Crafting Premium Hash
The world of cannabis concentrates has grown exponentially in recent years, with various methods and techniques emerging to extract the purest forms of resin and flavor. Among the most revered techniques is bubble hash—a solventless concentrate created using ice water and agitation to separate trichomes from the plant material. Anthony, from HPI Canna, is an expert in the craft, and he’s here to walk us through the precise and artful process of making bubble hash.
HPI Canna, known for its commitment to quality and sustainable cannabis production, has mastered the art of producing top-tier bubble hash. In this exclusive breakdown, Anthony takes us step-by-step through the process, showing how the brand makes its signature solventless concentrates with care and precision.
Fresh Frozen Flower: The Secret to Superior Bubble Hash
The journey to crafting premium bubble hash begins long before the agitation process. According to Anthony, the key to making high-quality bubble hash starts with the raw material. At HPI Canna, they use fresh frozen flower—a method where the cannabis is harvested and immediately frozen to preserve its trichomes and terpenes.

“Fresh frozen is the best way to go if you want to maintain the full essence of the plant,” says Anthony. Freezing the cannabis immediately after harvest locks in all the valuable compounds, ensuring that the hash-making process yields the highest-quality product possible.
Pre-Soaking: Preparing the Material
Once the fresh frozen flower is ready, the next step is to load it into the bubble hash machine. The machine is designed specifically for the delicate process of washing the cannabis material. Before anything happens, Anthony ensures the material undergoes a pre-soak in cold water.
“This helps to break down the trichomes and separate them from the plant matter,” Anthony explains. The pre-soak step ensures that the trichomes are ready to be collected efficiently in the subsequent agitation phase. Without this crucial step, the overall yield of hash might be lower, and the quality may suffer.
The Agitation Process: Separating the Trichomes
After the material has been pre-soaked, it’s time for the main event: agitation. Using the bubble hash machine, Anthony and his team agitate the fresh frozen cannabis in ice water, a crucial phase where the trichomes are detached from the plant material. The combination of cold water, ice, and gentle agitation causes the trichomes—the tiny, resin-filled glands on the surface of cannabis flowers—to break off and fall into the water.
The agitation process is one of the most critical steps in bubble hash production. If done correctly, it results in a high-quality concentrate, rich in terpenes and cannabinoids. "You want to make sure the agitation is gentle but thorough," Anthony notes. “Too much force can damage the trichomes, and too little won’t separate them properly.”
Draining the Water and Collecting the Hash
Once the agitation process is complete, it's time to drain the water into specialized bubble bags. These bags are equipped with different micron-sized filters, which allow for the separation of different grades of hash. Each bag will collect varying grades of hash, from the finest, most potent material to more coarse hash.
“We use different micron bags to separate the material based on its quality,” says Anthony. “The finer the micron, the purer the hash. The goal is to get as much of the trichome head in the bags as possible.” This step results in a multi-layered hash collection, each grade differing in purity and potency, giving consumers a choice of products based on their preferences.
Freeze Drying: The Final Touch for Freshness and Potency
After collecting the bubble hash, the next crucial step is freeze-drying. The freshly collected hash is placed in freeze dryers to preserve its flavor, potency, and overall quality. Freeze-drying is an essential step because it removes the moisture from the hash without using heat, which can degrade the delicate terpenes and cannabinoids.
“The freeze dryer helps to ensure that the final product maintains all of its flavors and effects,” Anthony says. Freeze drying not only keeps the hash fresh but also contributes to its stability, ensuring that the product will remain potent and flavorful even after storage.
The Art of Bubble Hash
Making bubble hash is both a science and an art, with each step requiring attention to detail and a passion for the craft. From selecting the best fresh frozen flower to carefully agitating, draining, and freeze-drying, every part of the process is essential to producing top-quality solventless concentrate. At HPI Canna, Anthony and his team take great pride in their bubble hash production, with every batch representing their dedication to quality, sustainability, and the cannabis culture.
