What is Homogenization in Solventless Extracts?

Homogenization means combining different consistencies into one uniform consistency. In terms of cannabis concentrates, homogenization is creating a substance of the same texture throughout, as opposed to solid forms and liquid forms that exist together. For example, hash rosin often separates into solid crystalline structures surrounded by pools of liquid terpenes. Different methods can be used to combine these two distinct components of rosin into one uniform consistency.

The Endocannabinoid System and Cannabis

Humans have been using cannabis for thousands of years. The history of human experience has included cannabis for health and wellness and recreation. It’s been a love affair that’s not going away, and for good reason. In some ways, it seems that humans and the cannabis plant were made for each other. The active compounds in cannabis called cannabinoids fit like a hand in glove with a system of receptors in our bodies known as the Endocannabinoid System. So what exactly are cannabinoids? Cannabinoids are the naturally occurring compounds

Difference between Pillow Tech, Bottle Tech, and Chottle Tech

In the art of rosin extraction, there are several different methods that extractors can use to accomplish the same goal. For example, all rosin extraction involves pressing cannabis material between heated plates, but there are a variety of ways to pack the starting material into filter bags and position it between the plates. These different approaches are referred to as techniques, or “tech” for short. Pillow Tech, Bottle Tech, and Chottle Tech are different ways that rosin filter bags can be used to hold starting material, and how that material is oriented between rosin plates for extraction.

What's The Problem with Using Dry Ice for Dry Sifting?

Dry ice is the solid form of carbon dioxide, capable of achieving temperatures much lower than that of regular ice. Unlike water ice that changes from a solid to a liquid when it melts, dry ice sublimates as it warms up, meaning it changes from a solid directly into a gas vapor. This vapor cools the surrounding environment, which makes dry ice an effective cooling agent. At more than 100 degrees below zero, dry ice gets so cold that it can actually damage unprotected skin. One of the mantras often heard when working with solventless cannabis extracts like bubble hash and dry sift is “keep tools and environment cold”.

Top 5 Bubble Hash Drying Tips

Ice water extraction is the ideal method used to create high quality bubble hash. While other methods like dry sifting can produce excellent solventless concentrates, ice water offers extractors greater control over isolating trichomes and removing plant contaminants. But after extraction is complete a lot of water still remains, leaving a totally saturated patty of cannabis trichomes. Not only is the hash unusable in this state, but it’s vulnerable to microbial growth like mold. Just like fruits and other foods, bubble hash can invite microbial growth if there’s sufficient moisture present.

Aging Bubble Hash 101

There’s much more to aging bubble hash than simply the passage of time. Without proper preparations and a controlled environment, hash is just getting older in long term storage, not really aging like a fine wine, tobacco, or cheese. There isn’t yet much scientific research that gives us a clear understanding of the chemistry behind the magic of aging bubble hash, but we still have data. That data comes from human experience, passed down through the traditions developed over thousands of years in hash producing regions of the world.

Rosin Press Hand Pump Modifications

There are several types of rosin presses capable of producing high quality rosin, spanning the range between hair straighteners and fully automated pneumatic presses. Hair straighteners are the most manual of all presses, which require all the pressure to come directly from the weight of the extractor pressing down on the plates. Pneumatic presses are the most automated, using compressed air to generate internal pressure which is controlled by the simple push of a button

How To Prepare Fresh Frozen Cannabis and Average Yield for Washing Bubble Hash

Fresh frozen cannabis is a type of starting material used in the ice water extraction method of creating bubble hash. The difference between fresh frozen and other types of cannabis material, such as dried and cured flowers, is in the specific treatment of the material after harvest. Fresh frozen cannabis is grown in the same way as cannabis destined to be air cured in the traditional fashion, but rather than hung to dry, fresh frozen cannabis is harvested and then immediately frozen at subzero temperatures.

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.
