4 ways to make hashish at home


Why do we have hashish?

Making hashish is a wonderful way to keep it productive long after harvest. Whether in the kitchen or in the laboratory, the manufacture of hashish is a process accessible to all. Using the old school methods or the new techniques of the market, the process is relatively simple: shake, sift, remove trichomes, collect resin, sort resin by size, dry resin, smoke and enjoy! Ed Rosenthal aka the Guru of Ganja gives us his secrets.

What are the ways to make Hash?


Water and ice can be used to mechanically separate trichomes from the plant and sieves can concentrate the trichome glands into uncompressed or "free" hashish.



Further refinement using machines and tighter control of temperature and humidity will result in the strongest solvent-free concentrates.


Squeezing unrefined hashish into balls, cakes or plates is a two-step process: First, the trichome glands are collected; then the collected material is compressed into bricks or balls.


Hashing involves a combination of strength and mild heat to condense the glands into a solid mass. The shape and size of hashish varies depending on the pressing method. When pressed by hand, the hashish is often ball-shaped. The hashish pressed flat can look like thin shale rock, with hardened layers in the form of shelves that flake along the folds. The mechanically pressed mince is usually a clean cake, like a bar of soap.


What good hashish looks like

Hashish comes in color and flexibility. The variety used, the method of manufacture, the temperature and the purity of the kief influence its color. Its hue ranges from pale yellow to charcoal black and its texture ranges from soft to hard and brittle.

Hashish oxidizes and darkens under the effect of light, oxygen and heat. Whatever its texture, high quality hashish has to soften with the warmth of your hands.


How to squeeze Kief or Water Hash?

Before attempting to compress the kief or water chop, the material must be completely dry. To ensure that all moisture has been removed before pressing, dry one last time: here are different drying methods.

  • Place the kief or water hash in a food dehydrator set to the lowest
  • In a horticultural heating mat preset to 23˚C
  • In the microwave at very low temperature
  • In an open dish in a freezer free from frost

Vacuum conditions promote the evaporation of water, preventing mold from infecting and wasting the hashish. However, when the drying temperature is above 24˚C, some terpenes will evaporate, reducing the kief's unique odors and their effects.

Pressing transforms matter both chemically and physically; the trichome glands are warmed and most break down, releasing the sticky oils that contain the psychoactive cannabinoids, as well as the terpenes that are the source of the smell, taste and after effects of cannabis.

Terpenes perfume hashish. The smells and tastes characteristic of hashish range from pungent or peppery to floral. Many terpenes are volatile at room temperature. When inhaled, they contribute to lung expansion (cough factor) and taste. The aged kief is both sweeter in smell and flavor, and less coughy, as some terpenes (but not THC) have dissipated.

The release and warming of the cannabinoids exposes them to the air. This has the beneficial effect of potentiating THC by decarboxylation. Continuous exposure to light, air, heat and moisture causes THC to deteriorate.

You can press the hash manually or mechanically. Manual methods work well for small quantities. Mechanical methods use a press, which is fast, convenient and efficient.

Here are 4 ways to make hashish at home

Method of manufacturing hashish with (clean) shoes

This pressing method allows you to multitask. While you're busy doing something else, the hashish is quietly pressed into your shoe!

Hashish pressing is an easy way to squeeze a small amount of kief or hachi into the water. A few grams, usually 5 grams or less, are wrapped in cellophane or parchment paper wrapped around the material several times. A piece of tape prevents him from deploying. Pierce a pinhole in the package to allow trapped air to escape. Do not use a plastic bag because the hashish sticks in a messy way. It is important that the material is securely sealed before it enters your shoe.

Place the package inside the heel of your shoe. Hard-soled shoes or boots are better for pressing than soft-soled shoes, such as sneakers, which take longer to process the kief.

The weight and pressure of the heel inside the shoe, helped by the heat of the body, compresses the hashish in a slab. This pressing lasts from 15 minutes to one hour of activity.

Kief pressing or compression in the hand

Hand pressing is a method of turning kief into hashish of a few grams at a time. Hand pressing is convenient because it does not require additional equipment but it requires considerable energy and the results are better with a practiced technique. Those who are not used to hand pressing may have difficulty linking materials to each other. The considerable work that is required to squeeze hashish can easily result in painful hands.

This method works best using medium to high grade freshly sieved kief. If the kief contains a significant amount of plant material, it is more difficult to mold and may not stick properly. To squeeze by hand, make a small fresh pile that will hold comfortably in the hand, usually a few grams at most. Work it from one hand to the other until it starts to form a solid piece. Then, rub it between the palms of the hands or between the palm and the thumb. After 10 minutes or more it will begin to change density. The dry and aged kief does not have some of its original adhesiveness and may take longer to stick together but if it has been stored properly, it should cooperate, although it may require more kneading. When a piece of hashish has not been pressed properly, it crumbles easily at room temperature.

If the kief is particularly stubborn and does not want to stick to form a mass, heat it slightly. Wrap it in food grade cellophane, making sure it is completely sealed and all the air is expelled. Wrap this package in several layers of wet newspaper, cloth or paper towels. Turn frequently, heat in a frying pan over low heat. It does not need to be heated as long as the other methods because the only point of heating is to glue the material so that it can be kneaded into a solid piece.

Another method is to wrap it in the same way and press it a few seconds on each side with an iron set at very low temperature.

Method of manufacture with hot water bottles

The concept of using the hot water bottle method is similar to hand pressing. However, more heat is applied to completely melt the waxy cuticle of each trichome head. This method works with a medium high quality resin that is dry to the bone.

BHO vs. CO2

Place a pile of resin on the surface of organic cellophane or parchment paper. Fold the paper in half. Bring the water to a boil. Fill a bottle of wine with hot water. Allow the bottle to cool for 5 minutes. Place the bottle of mulled wine over the resin covered with paper and let it sit for 30 seconds.

Look through the bottle to the dark spot of the warming resin. If the color changes quickly, you have the sign that the resin will squeeze very quickly. If the resin just starts to change after 30 seconds, you will have to work the resin a lot more. In a series of passes, roll the wine bottle over the resin with minimal pressure. Allow the heat to melt the material without forcing, using the pressure of your hand. Flip the paper over and do the same on the other side.

The resin should no longer be a mound, but rather a flat slab and a slab: if it is not quite so. With a simple movement of the wrist, open the paper. The resin must be sticky and have a nice shine. Fold the resin in half, then fold and start squeezing again. Repeat this process again before taking the hot resin in the palm of your hand.

To create a modern "temple ball", roll the ball like a mass of clay. Roll it up with firm pressure; compress the resin together and remove the excess air. Resin that has bumps, wrinkles and fine lines needs to be worked deeper. Continue rolling the resin until you are satisfied with the mass in your hand.

With a resin of very high quality, the result will be a mass of resin completely melted and brilliant, ready to be stored.

Mechanical press manufacturing process

Making hash is a breeze with a mechanical press. Binding presses can also be used. Plans are available on the web for the construction of a press using a hydraulic cylinder.

Manual pump hydraulic presses are a cheaper way to get a tight press. Another cost-effective method uses a vise-grip, although it does require some adaptation.

For small quantities, a pollen press can be used with a pocket pollen collection mill, the kief adds to this small metal tube. The clamping pin is put in place and the pollen press is screwed on. The next day, the kief was squeezed into a clean hash block. Many companies today have similar presses, including one in stainless steel with a low torque T-handle.

How to store hashish

Once the hashish is pressed, it can be stored for months or years, with little deterioration in potency and flavor, with proper storage. A frost free freezer is the best place to keep hashish.

Containers made of metal, glass or silicone are preferable for storage. Plastics and rubber are not recommended because the terpenes responsible for the flavor and aroma of hashish are somewhat volatile compounds that interact chemically with plastic or rubber, degrading both hashish and the container. However, this occurs slowly under freezing conditions.

Over time, the outer layer of hashish oxidizes and loses its power. The interior, not exposed to light and oxygen, remains powerful. Remember that soft light, heat, moisture and oxygen oxidize the exterior of hashish, destroying its power.
