What Is the Purpose of Aging Bubble Hash?

The transformations in bubble hash that take place over time seem magical, in part because a scientific understanding of what’s happening, and why, still isn’t clear. Texture, taste, and smell of hash change as the product ages, and there are certain things that a hashishin can do to allow the passage of time to enhance instead of degrade. The goal of aging bubble hash is comparable to aging wine or whiskey. An 18 year old scotch is more desirable than a 2-year. It becomes smoother and more mellow over time, yet also more complex and intriguing to the senses.

How To Cure Cannabis Flowers

Curing is the process of slowly reducing moisture content in cannabis flowers within a controlled environment over multiple weeks or months. Although curing involves the evaporation of water content from cannabis, it’s not the same thing as the initial drying process which takes place immediately after harvest. First cannabis is harvested, then it’s hung to dry, then it’s cured. But what are the benefits to curing cannabis flowers, and is it always necessary?

How Long to Mix Cannabis and Ice Water for Washing Bubble Hash

Washing hash involves mixing ice water and cannabis material together in order to separate trichome heads and isolate them through a series of mesh filter bags. The same material can be washed multiple times, and for varying lengths of time with each round of washing. The length of washing time impacts the number of trichomes released from the material, as well as the amount of plant contaminant that may end up in your hash.

How To Harvest Cannabis for Peak Trichome Ripeness

In order to enjoy the fullest potential of what the cannabis plant has to offer, it’s important to harvest when its flowers are producing the maximum amount of therapeutic compounds. If the flowers are harvested too early, many of the beneficial compounds exist only in their precursor forms or in underwhelming amounts. If harvested too late, the cannabinoid content may begin to decrease or convert into compounds with less desirable effects. Therefore, harvesting at peak ripeness is key

What Causes Color Differences in Rosin?

Light color is a positive indicator of quality in the world of solventless cannabis extracts. Off white with a slightly golden hue, like a very light honey, conveys the purity of a concentrate made up almost entirely of fresh resin heads. A light color demonstrates a lack of plant contaminants, which is always the goal in creating solventless extracts. What else can color differences tell us about rosin? There are multiple variables that can impact the color of rosin.

What Are the Benefits of Whipping Rosin?

Whipping rosin is a common practice, yet it’s also a point of contention in the solventless community. Some extractors whip rosin to stabilize an otherwise unstable product, willingly sacrificing some terpene content for an unchanging consistency. Others refuse to intentionally modify fresh rosin, opting instead to preserve rosin in its natural and potentially shape-shifting form. What does it mean to whip rosin?

What Is Tissue Culture Propagation?

Tissue culture propagation is a way to copy and preserve cannabis genetics, similar to traditional cloning methods in some ways but different in others. Tissue culture propagation, or TC, is a technique that involves cutting small pieces of plant tissue and placing it in meticulously controlled growing environments where both roots and stems can develop. Essentially, TC is like growing cannabis in a test tube. The process looks more like something you’d see in a scientific lab rather than a greenhouse. Dedication to cleanliness and attention to detail are both prerequisites to a successful micropropagation program.

What Is Ice Nucleation in Fresh Frozen Cannabis?

Like humans, living cannabis plants are composed mostly of water. At around 80% of their total weight, water accounts for the bulk of a cannabis plant’s biomass. After harvest, water slowly evaporates during the drying and curing process. But cannabis doesn’t have to be air dried in preparation for hash production. Fresh frozen cannabis has become the predominant source material for creating bubble hash and hash rosin. Freezing cannabis immediately after harvest allows us to capture and preserve the high terpene content that’s present in the living plant

Why Does Ice Water Change Colors When Washing Hash?

Cannabis material that’s properly washed for bubble hash often imparts a cloudy appearance in the wash due to thousands of trichome heads released into the ice water and cannabis mixture. It’s common to see an off-white color in the hash water, indicative of the resin that’s been effectively separated and left suspended in the water. In addition to the cloudy, creamy look of hash water, a greenish hue is also common. Green water is a sign of plant contamination and an early indicator that the quality of your hash may be compromised.

Average Bubble Hash Washing Yields

Bubble hash is one of the cleanest and most versatile of all solventless cannabis concentrates. Made with just cannabis, ice water, and a series of filter bags, bubble hash is relatively easy to produce with minimal equipment and processing time. Bubble hash, or ice water hash as it’s also called, can be enjoyed by itself or used as starting material for hash rosin production. When cannabis material is mixed with ice and water, the resin glands which abound on quality cannabis are broken away from the plant left suspended in the ice water mixture. These resin glands, or trichome heads, are then filtered out of the water using a set of filter screens known as bubble hash washing bags.

Top 20 Best Tips for Washing Hash

Although hashish is an ancient form of solventless cannabis concentrate, the process of mixing ice water and cannabis flowers to produce it, the technique known as washing hash, is still a recent innovation. It wasn’t until the late 1980’s and early 90’s that the first hash runs were made by stirring together cold water and cannabis plant material, and gathering the resin as it separated from the rest of the material and settled to the bottom of a collection vessel. Later iterations of the process involved a series of filter screens to isolate and collect trichome heads from the slurry of ice water and cannabis.
