Dry sifting is a technique used to produce hash. This process involves the use of a screen to remove the heads and stalks of trichomes. The trichomes are the glandular structures that produce the active compounds of the cannabis plant.
A variety of specialized micron screens are available, which range in size and capacity. These screens break off the desired compounds in order to produce the highest quality hash.
Dry sifting can be done at home using a simple pollen box and mesh screen. Many experienced hash makers also use filter bags.
Dry sifting is an easy and inexpensive way to make hash. However, the process takes several steps. It requires a lot of patience and rhythm.
The first step is to collect the trichomes of the cannabis plant. To do this, you should place the plant in a bucket. After about fifteen minutes, you should stir it a few times. You should be able to see more trichomes when you press the buds.
Next, you will need to break the trichomes apart. If you do not do this, the trichomes will stick together and become super brittle. Also, the trichomes will be easier to dislodge when they are in contact with the sifter.
As you pass the material through the sieve, you should use two hands. This helps to reduce strain on the back and shoulders.
Depending on the quality of your dry sift, you can either use it for cooking, rosin or vaporization. When stored correctly, the hash will last for a very long time.
