For home growers looking to get the most out of every crop, the best quality trim and smaller buds are valuable commodities. The presence of sticky resin on any cannabis leaf material translates into a nicely concentrated draw – when handled properly.
Likewise, cheap buds or shakes often available at dispensaries can be turned into high-quality concentrates by anyone with a little work.
Several inexpensive home extraction methods make it fun and effective to separate trichomes from the trim and create a top-notch head stash. Here is an overview of good options.
Screening is the oldest form of hash making. It simply involves getting two to three different micron sizes of screens — preferably stretched on frames available at any quilt shop — and sifting the dried edge through the screens until the resin glands drop through the screens. The resin, or ‘kief’, coming through the finest screen of the smallest size is your purest and most valuable, while the coarser screens collect some green material, but also some decent mid-grade kief.
Bubble Hash Technique
Bubble Hash became popular in California in the early 2000s, where growers realized they could use ice water to freeze the trichomes of resinous leaf material. Similar to the sieving technique, sieves of different micron sizes (in the form of 5 gallon bucket liners) are used to separate different grades of the final product.
An agitator such as a drill with a stirring bit on the end is used to spin the trim in the ice water so that all the glands will separate, and the wet gunk on each layer of the “bubble bag” screens is collected and dried on coffee filter paper, after which it is pressed into balls or stones. With this method, you need to make sure it’s dry enough before pressing it, or else it could start to get moldy on the inside.
The term “bubble hash” comes from the fact that the finished product bubbles when you put a flame on it. Many smokers like the taste and feel of bubble hash.
Dry ice technology
Somewhere along the way, our ever-entrepreneurial stoner colleagues discovered that cold temperatures can be used to break down trichomes without getting the foliage wet. This is the dry ice technique. You can buy a kit that comes with the micron bags, a container, and a neoprene jacket to keep your hands from freezing. Place your dry trim in the container of broken dry ice pieces, seal it and shake it. Be careful with this stuff! You can burn yourself. Wear thick gloves, otherwise your skin will melt with the dry ice like superglue does with your fingertips. As with the other methods, the time you spend stirring the trim, along with the screen micron size, will determine the purity of your results.
The resin technique is the latest and possibly the coolest of all of these hashing techniques because when done right it produces a pure glassy end product that can be compared to shatter, wax or BHO, but without the need for a solvent. This technique requires tips (no trimming), an electric hair straightener, a small scraper, and parchment paper. You simply take a folded piece of parchment paper, place a button in it and flatten the button between the heated ironing boards until the resin from the button melts and sticks to the paper. It can then be scraped off and stored before it cools and stiffens. Since this method involves heat, the THC is “decarboxylated” in the process, meaning that the potency of the resin is maximized. Buds are recommended for trimming as trimming would result in a prohibitive amount of leaf scraps ending up in the finished resin.
Some industry professionals are experimenting with T-shirt pressing to make the resin technique more feasible. And with the right type of high-temperature screen material, the use of trimming, rather than just topping, can be introduced, which would make this technique unbeatable as an inexpensive, high-quality, and high-yield option for making high-volume cannabis concentrates. quantities.
