How to Make Your Own Homemade Hash

Hash is one of the most effective and efficient cannabis products to try. Progress in trichome and resin separation allows for high quality (i.e. high content of main cannabinoids) to be achieved — that is not necessarily true for hash bought from dealers on the black market, however, and many people prefer to produce their own hash at home. Methods of trichome separation can be divided into three basic groups, which then give name to the final product: charas, kief and water hash; or manual separation, size-based separation and density-based separation respectively.

1. Charas

This method of manual separation, also called “hand-made” hash requires the least amount of special equipment, but the greatest amount of raw stuff compared to the other methods. The method requires time, a lot of experience and access to as much plants as you can get. You'll also need a pair of powder-free latex gloves to make this hand-made hash, which was given the name charas by its original producers in Nepal and India.

Charas can be made from any plant which has trichomes visible on the flowers. You'll get the most stuff in the time during or after the main flowering period however (approximately two weeks before harvest). At that time, you'll be getting ripe trichomes mainly each time you're collecting trichomes — as the harvest time approaches, more and more trichomes appear, allowing for repeated trichome collections. The older the plant, the greater is the probability that the resulting stuff will contain more leafy particles.

Before you start collecting trichomes, make sure you don't need to take a break in the process, whether for a snack, cigarette or to visit a bathroom. Your gloves (and maybe even forearms, depending on the size of your crop) will be covered in a sticky layer with properties very similar to depilatory wax.

After putting your latex gloves on, head to the field and start rubbing the buds, gently at first, then thoroughly, from the top along all of their length. Try to touch as much trichomes as possible, be careful not to miss any part of the bud. Keep in mind that the goal here is to “pop” the trichomes — and you'll need to apply adequate force. If you are ripping whole blooms and petals in the process, you're using too much strength.

After going through all of the harvest, take your latex gloves off and put them into a freezer. After a few hours in the cold, the resin will start to peel from the surface easily. Press the resulting product — after that, it is ready for vaporization or smoking.


2. Kief

Size-based separation, also known as “dry sieving”, is the most widely used way of production of commonly available hash on the black market. The principle behind the method is quite simple — trichomes are small, whereas (most) other parts of the plant are large. Rubbing or shaking the plant on the surface of a sieve will get you a relatively pure powder, which can then be pressed to form hash.

Devices and tools for this method of hash production are produced in all possible shapes and sizes. A good example would be the so-called pollinator, invented in the Netherlands. Simply put, it's a cylindrical-shaped sieve, into which you put well-dried hemp, ideally loaded with trichomes, and rotate it slowly. Sieved trichomes gather on a tray beneath the sieve. Another popular device for trichome collecting is known as “kief box”. It's a hand-made wooden box.

It is possible, however, to make your own sieve for dry-sieved hash production yourself. You'll need two reliably closable boxes which fit into each other tightly. You may use any two food boxes — the main point is for the small box to fit right in to the bigger one. You'll also need a piece of thinly woven nylon or silk fabric — you may use a nylon sock or a silk scarf.

First, remove the bottom of the inner box — scissors and dexterous hands should do the trick. Strain the nylon or silk fabric over the hole of the bigger box and press the smaller box through it inside, so that it holds tight in the place.

For increased output, you may put cannabis to a freezer both before and during the sieving. Make sure to wait for a while between sieving individual doses so as not to lose valuable trichomes to the air whirling in the sieves.

Lay the well-dried stuff with ripe trichomes straight on the tight fabric, close the inner box tight and start shaking the sieve strongly and thoroughly. If you hit the box against your palm or a table once in the while, it will help the loosening of the trichomes. After sieving all of the stuff, start again and repeat the whole process three times.

Finally, let the box content settle down and carefully remove the inner box from the bigger one — there are all the sieved trichomes beneath the sieve. If you don’t intent to consume the hash right away, thoroughly dry the trichomes to prevent possible mold. Spread the powder out on a piece of black and white newspaper or on an unprinted pasteboard and leave it in a warm spot without draft overnight. For common transport, it is best to press the resulting stuff afterwards.

3. Water Hash

This simple recipe has been around since the hippie era of 1960s. In California, this method was made famous by none other than Ed Rosenthal, the legendary American grower and legalization activist. Maybe that's why this wet method of hash production is so popular in California to this day, especially in the north of the state. If you stick to the instructions below, you'll get a handful of very pure, sticky and quality hash.


1. First, cut grinded buds and petals, which you had put in the freezer after the harvest, into pieces about two centimeters (0.8 inches) long. Use a sharp or serrated knife. Thanks to this preparatory step, it will be easier to separate trichomes from the rest of the stuff.

2. Fill a container up to its third with it.

3. Pour in just enough water to cover the plant material. You'll need to pour some of the water out in case you added too much.

4. Once cannabis is submerged, add ice (about two percent of the container volume).

5. For stirring, a strong drill with a long, strong, bicycle-pedal shaped extension would be best. A classic drill usually isn't effective enough for stirring the frozen stuff. Thanks to stirring, the trichomes get perfectly separated. The time of the production depends on the amount of stuff used.

6. Collect the foam which has formed during the stirring from the surface and dispose of it.

7. Separate the trichome-containing water from the vegetal stuff by sieving it through a sieve. It is necessary to stir the water quickly in the process.

8. What remains of the plant can still be used for baking.

9. After straining the water to a prepared container, make sure to flush the rest of the stuff to it once more. That way, you'll not lose the trichomes which have remained in the remains of the plant.

10. Collect the trichomes using two filters. As a first filter, use a mesh bag inserted in another container.

11. Place a second mesh bag with larger holes, fixed to a frame, above this container. As you're pouring the water from the container where all the trichomes are, the first bag will catch the larger particles of the plant material and the other bag will catch even the finest ones.

12. Slowly raise the mix of water and crystals caught in the finer bag from the container and wait before the water drips away. Wring any excessive water.

Let the hash dry out outdoors for a couple of days before smoking it, as the fresh product may be a bit irritant.
