![]() ![]() Both a rosin press and a rosin bag use pressure and heat to force the trichomes out of the cannabis leaves and buds. Rosin is a viscous sap whose appearance can range from clear to very dark, and it can be used in its extracted form or as a base for cannabis edibles. It is also a pretty wholesome method of extraction that leaves you with most of the cannabinoids intact. Because it uses water, this method is considered to be one of the safest and cleanest ways of making a pure, high-quality hash that has no impurities. The resin is separated by the mechanical force and it is collected. In this method, the cannabis is placed in a simple jar or bubbleator with water and ice and agitated. It is the brainchild of Neville Schoenmakers, founder of the first Cannabis Seed Bank. The kief is then graded based on the level of purity.īubble hash is a popular cannabis extract that is made using kief that has been Ice Water Extracted. The cannabis plant material is passed through a mesh and the kief collects at the bottom. One technique that has stood the test of time and is exceptionally safe is the use of a mesh. Kief, a type of cannabis concentrate, can be made using different mechanical techniques. Shaking, Sifting, and Dry Sifting-Used to Make Kief This is because the concentrates produced through this method are relatively safer. Solventless extraction is often used when creating concentrates for medicinal use. Non-Solvent-Based Methods for Making Cannabis Concentrates This means that it extracts impurities such as chlorophyll, which may affect the quality of the final extract. However, ethanol has a higher polarity than butane. The next step is to eliminate the solvent and remain with the cannabis extract. With ethanol, the solvent is dripped over the flowers and buds of the cannabis plant, which dissolves these compounds. It follows the same principle used in creating BHO. Because CO2 is a green gas, the extract produced through this method is relatively safe.Įthanol is a popular solvent used to make super-concentrated Rick Simpson Oil. It is then passed through the cannabis plant material in a closed loop system to extract the compounds and then the CO2 is evaporated. The carbon dioxide is subjected to supercritical conditions that causes it to fluctuate between a gas, liquid, and solid-state. Supercritical CO2 extraction uses CO2 to separate the different compounds from the cannabis plant material. The cost of blast proofing a room could be around $100,000. It is also a requirement for manufactures using hydrocarbons to blast-proof the premises. Securing the equipment could cost upwards of $30,000 for an average-sized model. When flammable compounds are present, open loop systems can easily cause a fire accident.Ĭlosed-loop systems, on the other hand, are safer but more expensive to implement. ![]() Open-loop systems have exposure to the external environment. The process of extracting cannabis can be either open-looped or closed-looped. Hydrocarbons are used to make butane hash oils (BHO) which includes budder, sauce, wax, shatter, and crumble among others.īecause hydrocarbons are highly flammable, a closed loop system of extraction should be used. Hydrocarbons (Butane, Propane, Hexane, etc.) Let us look in detail at how these solvents work. This method yields what is known as a cannabis concentrate.Īs discussed earlier, the solvent-based extraction method has been used for quite a long while now. Instead, the resin is pressed, beaten, or rubbed out of the plant, resulting in kief, rosin, or hash. Mechanical or solventless extraction: Mechanical or solventless extraction methods do not use solvents. This method yields what is known as a cannabis extract. The solvent is then removed, leaving behind extracts such as shatter, vape oil, or wax. Solvent-based extraction: In this method, solvents are added to the plant material to dissolve the resin, which is the concentrated part of the cannabis plant containing the cannabinoids and terpenes. When it comes to cannabis extraction, two main methods exist. What Are The Popular Methods of Cannabis Extraction? In recent times, the technology of extracting cannabis has grown in leaps and bounds, and we will take you through each of them in great detail. This was a precarious affair with consequences of explosive proportions, quite literally. This heralded the beginning of a new era.Īt the start, cannabis extracts were made using highly flammable hydrocarbons right in their backyards and garages. Not only were they more potent, but they were also a cleaner and a more convenient way to consume cannabis. These extracts varied from shatter to wax to batter to dabs and honey. Regular users started smoking less and dabbing more- heating oily extracts to inhale high concentrations of cannabis. At the turn of the century, cannabis enthusiasts began noticing a steep shift in the market. ![]()
