How to make pure hash, is one of the oldest and most beloved cannabis concentrates. Made from the resinous trichomes of the cannabis plant, pure hash is a potent and flavorful product that has been enjoyed for centuries. Whether you’re a cannabis enthusiast or a DIY connoisseur, learning how to make pure hash at home can be a rewarding experience. In this guide, we’ll walk you through the process of making pure hash, covering methods like bubble hash and dry sift hash, and sharing tips to ensure you create a high-quality cannabis concentrate.

How to make pure hash
Pure hash is a cannabis concentrate made by collecting and compressing the trichomes (resin glands) of the cannabis plant. These trichomes contain the cannabinoids, terpenes, and flavonoids that give cannabis its unique effects and flavors. The result is a potent, aromatic product that can be smoked, vaporized, or used in edibles.
There are several methods to make pure hash, including bubble hash, dry sift hash, and hand-rolling techniques. Each method has its own unique process, but all aim to separate the trichomes from the plant material to create a clean, concentrated product.

How to Make Pure Hash: Step-by-Step Guide
Gather Your Materials
Before you start, you’ll need the following supplies:
- High-quality cannabis flower or trim
- Ice water (for bubble hash)
- Bubble bags or a silk screen (for dry sift hash)
- A bucket or large container
- A mixing tool (spoon or paddle)
- Parchment paper
- A clean, flat surface for drying
- Gloves (optional)
2. Choose Your Method
There are two popular methods for making pure hash: bubble hash and dry sift hash. Here’s how to do both:

Method 1: How to Make Bubble Hash
Bubble hash is made using ice water to freeze and separate the trichomes from the plant material.
- Prepare the Ice Water Bath: Fill a bucket with ice and cold water. The cold temperature helps the trichomes become brittle and break off easily.
- Add Cannabis: Place your cannabis flower or trim into the bucket and stir gently for 15-20 minutes. This helps separate the trichomes from the plant material.
- Filter the Mixture: Pour the mixture through a series of bubble bags (micron screens) to filter out the plant material. The trichomes will collect in the finer screens.
- Collect the Hash: Scrape the collected trichomes from the screens and place them on parchment paper.
- Dry the Hash: Allow the hash to dry in a cool, dark place for 24-48 hours. Once dry, it’s ready to use!

Method 2: How to Make Dry Sift Hash
Dry sift hash is made by sifting dried cannabis through a fine screen to separate the trichomes.
- Freeze Your Cannabis: Place your cannabis in the freezer for a few hours. This makes the trichomes easier to separate.
- Sift the Cannabis: Place the frozen cannabis on a silk screen or mesh tray and gently shake or rub it. The trichomes will fall through the screen, leaving the plant material behind.
- Collect the Trichomes: Gather the sifted trichomes and compress them into hash using your hands or a press.
- Cure the Hash: Store the compressed hash in a cool, dark place for a few days to enhance its flavor and potency.
Tips for Making High-Quality Pure Hash
- Use high-quality cannabis flower or trim for the best results.
- Keep everything clean to avoid contaminating your hash.
- Be patient during the drying process to prevent mold or mildew.
- Experiment with different micron screens to achieve your desired consistency.
