What’s the Best Way to Make Hash at Home?
Hash is a collection of the extracted resin glands (trichomes) from a cannabis plant. The effects of hash are typically much stronger than straight cannabis flowers because trichomes contain concentrated amounts of THC, CBD and other cannabinoids. The two most common types of hash made at home may be bubble hash and dry-ice hash. After releasing tutorials on how to make your own Bubble Hash and Dry-Ice Hash, we received quite a few emails on the subject of hash. Everyone seems to love extracts in all forms, but there were two distinct opinions that kept showing up over and over again.
One group feels the dry-ice hash is the only way to go because bubble hash can be time consuming and doesn’t always get great yields.
The other group thinks bubble hash has the best potency/effects, and that dry-ice hash is an easy-to-make but less valuable extract.
Hash is basically the collection of trichomes from a marijuana plant. It’s much more potent than typical cannabis!
Honestly, I think they’re both great! But today, that’s not enough. Both types of hash are getting judged on certain attributes and we’ll figure out if one really is better than the other! In this experiment, the process of making bubble hash and dry-ice hash will be judged by these criteria:
- How pretty does it turn out?
- How hard is the technique?
- Yield (per ounce of material used)
- How much extract per ounce of weed?
- Perceived Potency
- How strong is it?
Alright, let’s get to the comparison!
How is Dry Ice Hash different?
Here’s another pertinent piece of info from the book Hashish!,
“The process of hash-making can be divided into two parts – resin collection, and resin preparation.”
Although not all hash is the same, many types of hash are pretty darn close. Water hash – also called ice hash, bubble hash, gravity(Gumby) hash, and dry ice hash all produce forms of the same product: isolated resin glands. The difference between methods comes down to how the resin is taken off the plant, and how the hash comes out afterward.
Although many methods produce the same or a similar product, using dry ice has advantages in many areas that end up making it superior to other means of resin collection:
- It’s faster than other methods.
- You can finish making dry ice hash in about 1/25th of the total time it takes to make gravity hash! Although that example is extreme, it only takes a few minutes to make dry ice hash and is much faster than other methods.
- It’s insanely easy
- And that ease translates to it being quickly gratifying. You get top grade hash at the cost of shaking a bucket and a bag for a combined total of less than 15 minutes.
- There’s no moisture!
- That means the resin is ready as soon as it’s shaken loose!
So, back to that quote: “The process of hash-making can be divided into two parts – resin collection, and resin preparation.”
We know that collecting the resin is easy with this method, but what about preparation? Let’s go back to ‘Hashish!’ one more time to see why we need ‘resin preparation’:
“Primarily, [preparation] makes resin powder a more easily transported and marketed commodity. Secondly, since early-smokers lacked metal pipe screens that could contain raw resin powder during smoking, they made the loose powder into solid pieces, convenient for smoking.”
In short, preparation makes your hash easier to sell and easier to use (if you’re somehow reading this 40 years in the past). In other words, it’s completely unnecessary in our case! We’ll save time and effort by skipping any post-processing, and there are no real drawbacks!
Safety considerations when making dry ice hashish.
Use a well ventilated room or an external area such as a garage. Your lungs need to absorb oxygen to survive but you will be using lots of carbon dioxide. In a closed room you could suffer oxygen deprivation, therefore it is vital to ensure excellent ventilation. Remember that dry ice can cause instant and severe skin/eye damage. Many hash fans are perfectly happy to leave dry ice extractions to the professionals for very good reasons. Don’t put dry ice in a sealed container, if it warms up and expands it could explode the container. Dispose of dry ice safely, don’t try to flush it down the toilet or sink as it can freeze them. Instead, simply place the unwanted CO2 pellets near an open window, door or garden and leave them to evaporate away naturally.
The dry ice method for making hash has two main attractors — it’s both cheap and easy. You also won’t need that much equipment or materials to get started, which means you’ll have a harvest of hash in no time. Some hash makers also claim that this method provides a more flavorful end product than other methods. At a temperature of −78.5°C, the dry ice effectively freezes and separates trichomes without the need to soak or sift cannabis material.
To make dry ice hash you will need the following materials:
- 2-3 pounds of dry ice broken into cube size pieces
- Dried or frozen cannabis plant matter (at least an ounce)
- Filter bags/bubble bags
- A large bucket
- A scraper
- A workbench, table, or other sufficient work surface.
- Safety equipment including heavy-duty gloves suitable for working with cryogens and goggles
- Place your plant matter into the bucket
- Wearing the gloves, add the dry ice
- Let this sit for 2-3 minutes to give the material time to freeze
- Empty the frozen cannabis and dry ice into a filter bag (a 160-micron bag is good for the first extraction although smaller micron bags may result in higher quality). *An alternate version of this step can be done by placing the filter bag in the bucket and then doing steps 1-3 above
- Shake the ice and plant material within the bag and/or bucket heavily for 2-3 minutes
- While shaking, the trichomes will freeze and pass through the filter bags onto your collection surface
- You can repeat the process with a higher numbered filter bag for an additional extraction
- Scrape the kief that has collected on the working surface into a storage container of your choice.
The fast-frozen plant material created by using dry ice will result in a powder or kief filtering through the filter bags. Pressing the kief converts it to hash. You can leave the hash as is or form it into a ball to resemble other forms of hash you might be familiar with.
Dry ice can be dangerous. Always wear productive gloves and goggles to protect your skin and eyes from freezing. And never keep dry ice in a fully-sealed container or use it in a poorly ventilated room. This can result in an explosion or suffocation.
There are several takes on how to make dry ice hash and you may want to experiment with the above to best suit your needs.
