What's the Difference: Home vs. Pharmaceutical Harvest Right Freeze Dryers & What We Recommend For Drying Bubble Hash

Freeze drying utilizes the process of sublimation to remove moisture from wet objects. Most commonly used for drying and preserving food, freeze dryers also work great for drying loose resin, or bubble hash. While it’s possible to allow wet hash to air dry loose resin through the process of evaporation, sublimation inside a freeze dryer speeds up the process, reducing oxidation and preserving more terpenes.

How to Use a Harvest Right Freeze Dryer to Make Bubble Hash (& Recommended Shelf Temp / Freeze Times)

Freeze drying is the ideal way to dry bubble hash. Loose resin that’s collected using ice water extraction comes out wet. If it’s not properly dried, it can quickly and easily get moldy. While it’s definitely possible to air dry bubble hash, and create a premium hash while doing so, there are some downsides to air drying. Air drying takes several days, and requires lots of space to spread the trichomes in a thin layer. Air drying also allows oxidation to occur

Can You Use the Same Water To Wash Bubble Hash Multiple Times?

Collecting loose resin via ice water extraction is a relatively low-cost and extremely effective way to make bubble hash. Everything starts with high quality cannabis material which are the mature flowers and trichome-covered leaves that surround them. Mixing cannabis with ice-cold water creates an environment where trichomes (most notably the globe-shaped heads of the trichomes) can fall away from the plant they once grew from. The heads get mixed in with everything else until the hash maker sieves them through a series of filters called bubble wash bags.

How to Use Gravity to Drain Water from a Bubble Hash Washing Vessel

Washing hash involves two main stages, agitating cannabis and ice water together, then running that water through a series of sieving bags called bubble wash bags. Agitation happens inside a mixing vessel, which could be an automatic washing machine, or a simple bucket or barrel that allows hash makers to mix cannabis and ice water with a paddle by hand. Washing machines come with a drain already installed, although it’s a good idea to change out the drainage hose if it’s a corrugated hose.

Top 10 Tips on How To Prepare Your Harvest for Fresh Frozen

Here at The Press Club, we love using fresh frozen cannabis to wash bubble hash. It’s tough to beat the explosive flavor, unmistakable aroma, and stunning clarity of loose resin that’s collected from cannabis harvested with fresh frozen preparations. Fresh frozen captures the most vibrant and unique qualities of the ripe cannabis flower, preserving terpenes and slowing down the process of oxidation to levels that dried and cured buds can’t match. While correctly harvesting cannabis for fresh frozen starting material isn’t the only trick to producing

Hash Wash Labeling: First vs Second Wash and Microns Collected

Hash makers collect loose resin multiple times, and from multiple wash bags, throughout the course of washing a single batch of cannabis material. The loose resin, or bubble hash, is gathered throughout the process in increments rather than collected in aggregate at the very end. This allows hash makers to differentiate between resin collected from the first wash all the way to the last wash, and from each individual sieving bag. The two primary phases of washing hash are mixing/agitation, and sieving.

How Does Terpene Volatility Affect Hash Rosin?

Bubble hash and rosin are two solventless cannabis concentrates both capable of chaning texture and consistency in rapid, sometimes unpredictable ways. This propensity for transformation is possible thanks to the volatile nature of high quality hash. So what is volatility, and how does it affect hash? Volatility can be defined as the tendency of a substance to evaporate at normal temperatures. Terpenes are the most volatile compounds in hash, and it’s largely the terpene content that determines how volatile a specific run of hash will be. Terpenes are hydrocarbon compounds

Gravity Drainage vs Hash Pump for Washing Bubble Hash

A hash pump is a specialized pump that moves trichome-infused water from one vessel to another during the ice water extraction. Hash pumps automate the movement of water from the mixing vessel into the collection vessel, which otherwise needs to happen with the force of gravity. In labs with certain constraints that make using gravity suboptimal, hash pumps are a great alternative to moving water efficiently. And most importantly, in a way that doesn’t damage trichomes in the process.

How To Use a Washing Machine to Make Bubble Hash

Compact, portable washing machines like the kind designed for small apartments and RVs are great for washing hash. Although they’re made to wash small loads of laundry, they can also do a great job of mixing together cannabis and ice water for making bubble hash. Especially for extractors running high volumes of material, washing machines are the way to go. Machines automate the mixing process that would otherwise be done by hand, adding efficiency and scalability to your operation.

How To Clean Your Washing Machine after Making Bubble Hash

Washing machines are a great way to automate the all-important mixing phase of ice water extraction or washing bubble hash. Washing hash involves mixing together ice water and cannabis, then sieving the mixture through a series of filters called bubble wash bags. Using a washing machine for mixing enhances the efficiency, consistency, and scalability of output, and is often the best choice for processors working through a high volume of material.

Breeding to Collect Trichomes

The term “Hash plant” has been around for decades. Most notably the term showed up in the Seed Bank Catalogue in the 1980’s and 90’s as a plant that was selected for its hash-like flavor. In this article I will be referencing the term “Hash plant” as a plant that was selected because of the overall quality and yield of the hash that was derived from the sieving process and not that the plant's chemical profile tastes like hash in flower form. With more people growing and selectively crossing plants, we are starting to see some very unique expressions coming out of some of these contemporary cannabis lines.

How To Set Up a Water Drainage System for Washing Bubble Hash

Solventless extractors use lots of water for washing bubble hash, the process of mixing together ice water and cannabis to isolate trichome heads for collection. Water is the key factor that makes it all possible. A drainage system for washing bubble hash controls the flow of runoff water that’s used in ice water extraction. Water plays a part in both mixing and rinsing, so lots of clean, cold water is required. Once water comes into contact with the cannabis material

What Causes Green Bubble Hash?

Although vibrant hues of green are often associated with high quality cannabis, it’s actually not a good look for bubble hash. Bubble hash is composed of cannabis trichome heads, the bulbous resin glands that give cannabis flowers that crystalline, sugary look. These heads range in color from clear to amber, but never green. Trichome heads appear clear in their early weeks of development, turn milky as they approach ripeness, then finally become amber as the resin inside reaches full maturity.

How To Build A Cold Room for Washing Bubble Hash

A cold environment is essential for washing hash. Loose resin is nearly impossible to work with in warm temperatures, as it becomes a greasy mess that’s difficult to sieve through mesh wash bags. Creating a dedicated cold room for working with hash is the best option for serious extractors. Cold rooms should house all the equipment you need to wash hash, in a clean and well-organized space.

Using A Drill To Wash Bubble Hash?

The mixing together of ice water and cannabis is probably the most consequential of the steps involved in the ice water extraction process of washing bubble hash. While sieving and drying are also imperative to the process, properly mixing at the outset is the number one prerequisite for success. Agitating ice cold water and cannabis together causes trichome heads to separate from their stalks, liberating the minuscule resin globes from the rest of the material.

How To Identify Cannabis Strains for Solventless Bubble Hash Production

Identifying strains that are best suited for ice water extraction helps extractors minimize wasted time and resources spent washing material that doesn’t yield desirable results. No matter how perfect the equipment, environment, and process, some cannabis cultivars just don’t dump loads of high quality resin. It all boils down to the trichomes, and that’s where extractors can make the most meaningful assessment of the plant’s potential for solventless bubble hash production.

What Is Zombie Bubble Hash?

Somewhere between the living and the dead, the world of zombies exists in an enigmatic limbo. While much less dramatic than the creatures popularized in contemporary culture, zombie bubble hash is definitely worth the attention of discerning cannabis connoisseurs. But how can hash be a little bit living and a little bit dead? Bubble hash, or ice water hash as it’s also called, is made with a solventless extraction method that involves mixing ice, water, and cannabis. Agitating cannabis and ice water together knocks trichomes free from the plant material on which they grow.
