How to Press Bubble Hash into Rosin

Have you ever wanted to make your own rosin straight from bubble hash at home? If you're a fan of cannabis concentrates, making homemade rosin from bubble hash is an enjoyable, rewarding, and relatively simple process.

Creating bubble hash rosin allows cannabis enthusiasts complete control over the extraction process and the final product. By using high-quality bubble hash and carefully controlling the pressing parameters, individuals can produce rosin that meets their specific preferences regarding potency, flavor, and consistency. 

Let's dive straight into the process.

What is Bubble Hash?

Bubble hash is a solventless cannabis concentrate made using ice water and shaking to separate the trichomes from the plant matter. Trichomes are the tiny resin glands on the surface of cannabis flower containing cannabinoids and terpenes responsible for the plant's effects and aroma.

As the cannabis industry matures, bubble hash rosin has made a name for itself as a high-quality, connoisseur-grade product type. Bubble hash products provide incredible flavor, capturing the essence of the plant from which it’s extracted, and are considered a "cleaner" product than many of its solvent-extracted counterparts.

What is Bubble Hash Rosin?

Bubble hash rosin is an extract made by pressing bubble hash into a potent and flavorful resin. Rosin is a popular choice among enthusiasts who prefer solventless extraction methods and want to create their own homemade products.

Extractors make rosin by applying heat and pressure to cannabis flower or hash. This process causes the trichomes to release their resin, which is then collected and pressed into a sticky and highly concentrated substance. This sticky and malleable substance can be used in various ways, such as dabbing or adding to joints or bowls.

Unlike other extraction techniques that utilize chemicals and closed-loop systems, pressing bubble hash into rosin is straightforward, simple, and easy to contain within a small space and limited budget. 

How to Make Rosin with Bubble Hash

Required items

  • Cannabis flower
  • Rosin press, either manual or hydraulic, depending on your budget
  • Heating source, if needed (many rosin presses come with this included)
  • Spoon
  • 25μ rosin bags (inner bag)
  • 160μ rosin bags (outer bag)
  • Parchment paper
  • Scraping tool
  • Straight Sided Glass Jar (U-line jars are best)
  • Nitrile Gloves

Making bubble hash

  1. First, place the cannabis plant material in a bucket filled with ice water. The cold temperature helps freeze the trichomes, making separating them easier. 
  2. Mix the plant material by hand or with a spoon to break off the trichomes. This agitation causes the trichomes to detach from the plant material and sink to the bottom of the bucket.
  3. Once the trichomes have settled at the bottom of the bucket, pour the mixture into the different-sized mesh bubble bags. Arrange the bags in a series of sizes, with the smallest screen size at the bottom. Pour the mixture into the bags, starting with the largest screen size and working your way down. The screens will filter out the plant material while allowing the trichomes to pass through. 
  4. After filtering the mixture, collect the trichomes and dry and cure them to remove any remaining moisture. This can be done by spreading the trichomes on a clean surface and allowing them to air dry. 
  5. Once dry, the bubble hash can be pressed into rosin or used in other cannabis products.

Pressing bubble hash into rosin

There are several techniques for pressing bubble hash into rosin, each with its own advantages and considerations. 

Hair straightener

This method involves placing a small amount of bubble hash between parchment paper and applying heat and pressure using the hair straightener. After pressing, collect the rosin from the parchment paper into a storage container. This technique is relatively simple and requires minimal equipment, making it a popular choice for beginners.

Manual press

This method uses a specialized press that applies heat and pressure to the bubble hash. The press usually consists of two heated plates that are manually operated to squeeze the hash. Manual rosin presses offer more control over temperature and pressure, resulting in higher-quality rosin. However, they can be more expensive and require more space than the hair straightener method.

Hydraulic press

These presses use hydraulic pressure to extract rosin from bubble hash. They offer precise control over temperature, pressure, and extraction time, resulting in consistent and high-quality rosin. Hydraulic rosin presses are often used by commercial producers or enthusiasts who prioritize efficiency and yield. However, they can be expensive and require a dedicated setup.

Temperature and pressure

Regardless of the technique used, it is essential to consider factors such as temperature, pressure, and duration of the press. The ideal temperature for pressing bubble hash into rosin is typically between 180°F and 220°F (82°C and 104°C). 

Higher temperatures can lead to darker and less flavorful rosin, while lower temperatures may result in lower yields. The pressure applied should sufficiently extract the rosin without causing excessive plant material contamination. The press duration can vary depending on the desired consistency and yield, but it is generally recommended to start with shorter presses and gradually increase the time if needed.


The final step is to put the hash rosin into a glass jar with a tight lid and allow it to “cure.” Although this is subjective, a cured product often tastes better and lasts longer than fresh press rosin. Curing from fresh-press rosin to shelf-stable budder can take three days to months. 

The Bottom Line

It is important to note that achieving high-quality homemade rosin from bubble hash requires practice and experimentation. Each batch of bubble hash may have different characteristics, so it is vital to adapt your pressing technique accordingly. Keep track of your process and adjust as needed to consistently produce the best rosin possible, all from the comfort of your home.
