Separating resin glands from foliage concentrates cannabinoids into dry powdered resin glands (kief*); when pressed into blocks, the resin concentrate is called hashish or hash. Resin glands can be separated using water. Solvents can also be used to separate cannabinoid-rich resin glands from foliage. Once separated from foliage, cannabinoids can remain suspended in a solvent such as butter, coconut butter (as a food), or alcohol (as a tincture), or the solvent can be removed so that concentrated oil remains.<\/p>\n\n\n\n

Resin glands are oil-based, and plant foliage is water-based. The two act differently, and this simple difference has been used for many years to separate resin glands from foliage. The first and most common form of separation is for the oily resin glands to accumulate on fingers and trimming tools. This is commonly referred to as “hand rub” or “finger” hashish.<\/p>\n\n\n\n

Resin can be collected by separating it from foliage and letting it fall through a sieve. Or it can be separated from foliage using a combination of cold water and sieves.<\/p>\n\n\n\n

Dry cannabis foliage and flower buds can also be sieved to separate resin glands. The resin, bits of foliage, and foreign matter fall through the sieve. The resulting powder below the sieve is called kief*. Europeans often mistakenly call it “pollen.”** This golden-colored resin dust is lightweight. It can easily be collected and pressed lightly together to form a ball. Kief is pressed to form hash.<\/p>\n\n\n\n

Kief<\/strong> consists of resin glands that are collected after passing through a sieve. Once pressed together, it forms hashish, also known as hash. The more resin in the processed cannabis, the more resinous the hashish. This chapter will touch on the basics of making hashish using safe extraction methods. Detailed information on chemical extraction methods using butane, acetate, different alcohols, and toxic dangerous solvents has been omitted because of possible health risks from explosion, fire, and fumes. Chemical damage may result from premature use of the end product before all solvents and residuals have been extracted. You can find much information on these subjects at many Internet sites.<\/p>\n\n\n\n

Pollen: <\/strong>In Europe and other parts of the world, sieved resin powder is called pollen. The term is used because the two look similar, but resin powder is not pollen. When you hear somebody talking about “pollen,” you know they are most likely referring to resin powder.<\/p>\n\n\n\n

Wet separation uses a similar principle to separate resin from foliage, except cannabis is immersed in cold water before passing through the separation screen. Once separated, wet resin is collected and dried.<\/p>\n\n\n\n

Resin can also be separated and concentrated with the use of solvents such as petroleum, fats, oils, and CO2.<\/p>\n\n\n\n

When concentrated in an alcohol or oil-based solvent, the solvent is removed, and a cannabinoid-potent liquid remains. This liquid, hash, or cannabis oil is usually very dense and increases in viscosity as it warms. The concentrate can also be manipulated with a vacuum to inject air and change the appearance of the end product.<\/p>\n\n\n\n

Before Making Hashish<\/h2>\n\n\n\n

Make sure your plants are as clean as possible before you begin to make hashish. Remove all stems and large or damaged leaves. Any oil-based residues on leaves will show up in the separated resin glands. For example, if extracting resin with water, you can see impurity residues as sheen of oil on the surface of the water. During the month before har- vest, do not use any harmful chemicals that leave residues. To avoid potential health risks after harvest, I prefer to use only water-based organic products.<\/p>\n\n\n\n

Leach growing medium with water for 5 days before harvest to remove built-up fertilizers in the soil and foliage. This will help ensure clean, sweet-tasting hash.<\/p>\n\n\n\n

See chapter 9, Harvest, Drying & Cur- ing, for more on washing plants with hydrogen peroxide (H2O2) at harvest.<\/p>\n\n\n\n

Freeze First:<\/strong> Once dry, freeze cannabis to prepare for making kief and pressing it into hashish. Place leaves in a paper bag or cardboard box in the freezer for an hour or longer. Remove them from the freezer, and use a dry or wet sieve to separate gland heads from foliage. Freezing makes it possible to collect more resin by making foliage and resin glands brittle. Cold, brittle resin glands snap off and separate easily from foliage.<\/p>\n\n\n\n

The yield from 7 ounces (198.4 gm) of leaves and small buds is between 0.2 and 0.7 ounces (5.7\u201319.8 gm) with the average around 0.36 ounces (10.2 gm). The quantity of hash produced depends upon the quality of the original material. Clean stems, large leaves with no visible resin, dead material, and any debris from leaves and buds before making kief. Male plants do contain resin with THC but much less overall than is contained by female plants. Outdoor plants are subject to wind, rain, and dust, which may prevent resin growth or cause much of the resin to be knocked off the plant. Plants protected in indoor and greenhouse environments exude as much resin as possible. Such plants with heavy resin are best for kief-making. Great hash also comes from the closely trimmed leaves around buds.<\/p>\n\n\n\n

Keep the entire hash operation clean. This is the key to keeping everything separated properly and having minimal contamination.<\/p>\n\n\n\n
