How Does A Closed Loop Recirculation System Work?

As the name suggests, a closed loop recirculation system is a configuration that lets hash makers recirculate and thereby reuse water during the Ice Water Extraction process of collecting loose resin, or bubble hash. The traditional approach to Ice Water Extraction does not involve recirculating water through the system, rather extractors dispose of the drainage water after it’s mixed with starting material and passes through the sieving bags.

Hash Contaminants & How To Keep Trichomes Clean

Sometimes, contamination in the form of bugs, dust, sand, and even pesticides can get caught in the sieving bags along with the resin. And contamination in the bags can easily lead to contamination in the final product. Therefore, the goal is to minimize all contaminants on the starting material as much as possible before starting the Ice Water Extraction process. While there will always be some level of contamination, even if it’s extremely limited, there are things that hash makers can do to keep trichomes clean during the growth, harvesting, and preparation phases leading up to extraction.

What is Korean Natural Farming (KNF) & Why It's Important To Solventless Rosin & Hash

Korean Natural Farming (KNF) is a farming/gardening protocol that was organized and popularized by Master Cho Han Kyu. This production method uses local and onsite fermentations of plants, fruits, and fish, as well as the culturing of microorganisms to regenerate land into a healthy and productive living soil. KNF is a very affordable and regenerative production method that reduces input costs for farms and home gardeners while helping to maximize yield potentials and quality.
