Guide To Various Forms of Solventless Cannabis Concentrates
Solventless cannabis concentrates are made by isolating, accumulating, and condensing cannabis trichomes into a pure and potent form, all without the use of chemical solvents like butane, CO2, or ethanol which are commonly used in other processing methods. Solventless techniques allow extractors to capture the most therapeutic compounds made in cannabis, namely the THC and terpene-rich resin that’s located within a flowering plant’s trichomes. While high quality extracts can also be created with the help of solvents, for exampleRead more
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.Read more
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.Read more
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.Read more
Dry Sifting Screen Lines Per Inch (LPI) To Micron Conversion
Solventless extraction relies on mechanical separation to isolate resin glands from cannabis material. Dry sifting, pressing rosin, and washing bubble hash are different types of solventless extraction that requires extractors to sieve a trichome-rich starting material with some form of nylon mesh filter. Depending on what type of extraction you’re doing, the sieves are slightly different in form but virtually the same in function. For washing bubble hash, these sieves are called bubble wash bags. Bubble wash bags look like regular open-top bags with a mesh filter sewn into the bottom of the bag.Read more
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 materialRead more
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.Read more
What is Pressing Rosin 101
Rosin is one of the purest and most potent forms of cannabis extracts available. Made through the concentration of trichomes and the oily resin they produce, rosin can take on a variety of appearances. Some rosin looks creamy and buttery, but it can appear runny and sappy too. Some rosin even looks like diamonds. It’s a versatile cannabis concentrate that gives extractors a lot of freedom in how they want to process it. Unlike other cannabis extracts, rosin isn’t made with any solventsRead more
Cultivating Cannabis Specifically for Resin Production
There are many different methods and techniques used in the cultivation of cannabis. Environmental factors, nutrition, water quality, light intensity, medium selection (soil, coco, rockwool, etc), pest management all play a roll in the health and wellbeing of your plants. When starting your garden having a plan and setting a schedule will help achieve the desired outcome. Are you planning on growing the biggest, densest nugs possible? Are you after killer bag appeal? Do you intend to wash your harvest and produce world class resin?Read more
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.Read more
Top 5 Common Mistakes When Pressing Flower Rosin
Pressing dried and cured cannabis flowers is a great way to get started in the world of solventless extractions. With a few buds, rosin filter bags, and a simple press (even a hair straightener will work), you can make dabs quickly and easily at home. Although pressing bubble hash yields a higher quality rosin overall, squishing flowers can still yield some impressive results. Cannabis flowers are accessible, relatively low cost, and don’t require multiple steps of processing before squishing. Flowers can give new extractors a feel for pressing rosin.Read more
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.Read more
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.Read more
Cannabis Nutrient Selection and Its Relation To Resin Color, Quality, and Clarity
Nutrient selection plays a large roll in the health of your plants, whether you choose organic or synthetic, it can affect the quality, color and clarity of the trichomes. Carefully testing and selecting the right products for your individual fertilizer requirements is crucial for a positive outcome when harvest time rolls around, Cannabis plants are comprised of the environmental and nutritional factors they are exposed to throughout their lifetime. As the roots absorb nutrients up into the plantRead more
Tips To Minimize Filter Bag Slippage Hydroplaning While Pressing Rosin
Rosin bag slippage is an issue that most extractors have had to deal with at one time or another. As press plates apply pressure to the starting material during extraction, the rosin bag should remain perfectly fixed in position. But sometimes, as pressure increases and rosin begins to flow, the rosin bag and material drift out of place. This slippage can create various problems like reduced yields and torn parchment paper.Read more
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.Read more
What Is WPFF?
There are several ways to prepare cannabis material for ice water extraction, or washing bubble hash. Traditionally, hash makers hung cannabis upside down to fully dry, prior to extracting the resin. Drying cannabis flowers, and then subsequently curing in glass jars, is the same preparation for smoking them as well. But throughout this process, exposure to the open air (even inside an environmentally-controlled drying room) leads to terpene loss and oxidation. But there’s another way to prepare cannabis right after harvest, that can minimize oxidation and also preserve the abundance of terpenes locked inside the plant trichomes.Read more
How To Build The Ultimate Indoor Grow Room Part 1

What's The Problem with Using 2-Way Humidity Packs To Rehydrate Cannabis Flowers?
2-way humidity packs are thin pouches that contain water vapor, natural salts, and food-grade thickeners which help regulate humidity levels within airtight spaces. Traditionally used by cigar aficionados to preserve moisture levels inside humidors, 2-way humidity packs have been adopted by the cannabis industry to keep flowers at just the right humidity. Relative Humidity, or RH, is a measurement of moisture in the air (given as a percentage), and helps us aim for the right amount of moisture within cannabis flowers.Read more
How To Microplane Bubble Hash for Air Drying
Microplaning bubble hash is a way to break apart fresh, wet bubble hash for drying after Ice Water Extraction. Hash that’s just pulled from bubble wash bags is soaking wet, and in order to air dry properly, it needs to be prepared accordingly. Wet hash sticks together in globulous patties. Even if it’s spread into a thin, uniform layer to air dry, it will still trap moisture within. Moisture locked inside can’t evaporate by itself in the open air, and this invites mold growth before the hash gets a chance to fully dry.Read more
What Is Food Grade Bubble Hash?
Bubble Hash, or Ice Water Hash as it’s also known, is a type of solventless cannabis concentrate known for its purity and potency. Bubble hash is made through a process called Ice Water Extraction, a method utilizing only ice, water, and cannabis material to extract trichomes from cannabis. Extractors sieve the ice water and cannabis mixture through a series of mesh filters, called Bubble Wash Bags, in order to isolate and collect cannabis trichomes. These trichomes, also collectively referred to as “resin”, are the main object of interestRead more
