When using dry ice, low temperature is used so it won’t degrade the full flavor of hash. You’re missing something great if you haven’t tried using dry ice in making hash.

Making Hash Through Dry Ice Extraction

Hash is the result of collecting resin glands from marijuana plants. The non-compressed version is called kief and it can be smoked or vaped. When it is compressed, it turns into shiny and sticky hash balls. The color of the hash will depend on its purity. It can appear as light brown.

Sizes of Hash Bag

73 – It works best at catching resin without a single bit of plant material. You will only collect the golden, potent substance.

160 – You will be able to get a mid-grade product with some green stuff. The quality is not similar to 73 but it’s considered a great result too.

220 – This size will let you draw out almost everything except for the stems and leaves. It will let you have more plant matter compared to the other sizes but it’s lesser than the actual flowers.

The product smells like a concentrated form of weed. You may or not skip this size When you prefer to do the extraction only once, choose size 160.

Prepare the Necessary Things:

Ground or shredded Weed (buds or leaves)

A sanitized, 5-gallon bucket

Some hash bags, pollen bags, or bubble bags

Dry ice for extraction (2 to 3 pounds or 2 kg)

A scraping for collecting resin glands from bags

Protective gear: heavy-duty oven gloves, safety glasses, and clothes with long sleeves

A flat surface for shaking the bags

A working place that is well ventilated


  1. Use a clean bucket where you place the trimmed buds and leaves. Place the dry ice plus the hash bags in the same bucket. Shake them together.
  2. The buds quickly cool down with the dry ice. The sticky resin gland also freezes. The low temperature converts trichomes into gas-like and brittle form.
  3. The mechanical shaking extracts the trichomes then you can collect the hash bags filled with resin glands when you turn the bucket upside down.
  4. Place the hash bags on a flat surface and scraped them. To ensure that you have collected all the bits. Repeat the process as necessary.
  5. You may add ice dry pellets if you want too. You can make your hash in different forms like making it into balls or making the texture loose or powdery kief.

It can instantly cause your skin or eye damage when not handled with care. Some hash fanatics would ask assistance from experts when doing the process of dry ice extraction.

  1. Never place dry ice in an airtight container as you will regret it. When it’s being covered, the container is pressurized so it eventually shoot off or the worst part is an explosion.
  2. It’s a big ‘NO’ to hold the dry ice with your bare hands and that’s why you need a reliable pair of gloves. The warmest temperature is -190.3 degrees Fahrenheit. It’s not lethal but you don’t want to experience freezing burn.
  3. Disposal of dry age also requires caution even it’s done without effort. Throwing it into your toilet bowl or sink would freeze the water pipes. All you need to do is leave it in a ventilated area to evaporate into a gas.


Dry ice extraction is the easiest and fastest way of hash production. This way would let you collect every bit of trichomes. You will also love its rich flavor. It’s something that you should worth trying.
