How To Make Dry Ice Hash

By using dry ice in a bucket with bubble bags you can turn weed into kief, which then can be pressed into hash. The cold separates the resin glands so they can be easily removed.

Using dry ice to make your kief that can then be used to be pressed into hash might be one of the best ways to get the resin glands off of your buds. The dry ice method is a handy trick to know for every hash lover, whether you decide to smoke the kief as is or decide to press it into hash.


To make hash you have to separate the resin from the buds, which results in kief. The kief is then pressed into hash, which is ready for consumption or to save it for later. Freezing the resin glands off of the buds is a very efficient way of acquiring kief. The cold freezes the resin glands which causes them to crystallise. When crystallised they break of off the buds so they can be easily removed.

Using dry ice might be the fastest, most efficient and perhaps the easiest way to make your hash. Because the dry ice evaporates almost instantly your buds never get wet and no trace of any solvent is left. It is also the fastest way of removing the resin glands; it is about 25 times faster than making gravity hash, making dry ice hash only takes a couple of minutes.


Dry ice is a relatively safe material to use if handled properly. Because dry ice turns directly into CO2 gas it’s better to work in a well ventilated area. The gas it forms expands, so do not put it in an airtight container. The top will blow off eventually or worse, the container could explode. Dry ice is also extremely cold, it gets -123,5 degrees Celsius at its warmest, so safety gloves are needed to make sure the dry ice does not get frozen stuck to your skin. Because dry ice gets so extremely cold make sure not to flush it down the toilet or put it down your sink. The dry ice could freeze your water pipes and they could break. The best way to dispose of your excess dry ice is to just leave it in a well ventilated area until it is dissolved into gas.


The different sizes of filters are expressed in microns. A filter with larger holes has a higher number on the scale of microns, the larger the holes are the more plant material is being let through into your final product. To give you an idea of what micron filters give which result here is a comparison:

73 micron filter: This is the smallest filter used, it will leave only the trichomes that were separated from the buds. This filter will leave you with an amber coloured kief that is very concentrated and potent.

90 to 160 micron filter: These filters will leave you with mid grade kief, it is still potent but more diluted with plant materials and therefor greener in colour.

220 micron filter: This filter will leave you with even more diluted kief but it is still less plant material than smoking buds and smells like a concentrated form of the weed you’ve used to make the kief. Most people don’t use these filters but they are worth a shot if you really want to get the most out of your buds resin glands.


hash dope dry ice method

Two bubble bags of 3,8 litre, one with a 73 micron filter and one with a 90 micron filter.
A bucket that is big enough to fit your bubble bags in.
A pair of safety gloves
A pollen press
A hammer
28,5 grams of high-grade weed
1 to 1,5 kilos of dry ice

28,5 grams of high-grade weed should yield you about 0.6 grams of kief that has a high grade and 2.9 grams of kief that is less potent.


Break the dry ice into smaller cubes of about 2,5 cm with the hammer, do this in the sink to make sure the dry ice does not fly all over the kitchen and make sure to wear the pair of safety gloves. To process 28,5 grams of weed you will need about two or three handfuls of dry ice in the bucket.

Put the weed on the bottom of your bucket and put the two to three handfuls of dry ice on top of the weed. Mix the dry ice and the weed gently by tossing it around in the bucket until it is thoroughly combined. Let the mixture of dry ice and weed rest for a couple of minutes in the bucket while putting the fine mesh bag on. Fit the bubble bag over the top of your bucket until it completely covers the top and then tie the bag off at the bottom.

Shake the bucket with the bubble bag in it for about two to three minutes; this also cools the bubble bag, after shaking invert the bucket with the 73 micron filter bag over a flat surface. Basically turn it upside down so the mixture falls out of the bucket and into the bubble bag. The fine mesh will make sure that the plant matter is contained while the THC is able to pass through. A larger micron filter will let more plant materials pass and therefor the kief that passes through will be more diluted and less potent.

Keep shaking the bucket and bag until the kief stops falling out; it should be of amber colouring. Shaking the bag and bucket should take you around two to three minutes tops. Make sure to also collect what sticks to the bottom of the bag by brushing it off after the kief stops falling out of the bag and scrape what has been collected together with a thin flat card like a credit card into one big pile.

Repeat the procedure using the remaining dry ice and the weed that has been left over from collecting the kief with the 73 micron bubble bag but this time with the 90 micron mesh filter bag. The collected kief should be more of a greenish colour than the previously collected kief with the 73 micron filter bag because it is more diluted with plant materials. It is of lesser quality than the amber kief but still very potent and full of taste.

Weigh the piles of collected kief separately on a sensitive scale: you should now have around 0.6 grams of undiluted amber kief and 2.9 grams of greenish more diluted kief. This kief is now ready to be processed in the pollen press to pellets of compressed hash.
