Dry-Ice Hash skips the water altogether but keeps the agitation. Dry ice is made out of frozen CO2, and turns into a dry vapor as it warms (instead of water like regular ice). Dry-ice is so cold that it gets the resin glands to freeze, making them easy to break off. The dry-ice and weed are placed in the same type of sieve you would use for Bubble Hash and agitated until resin falls out onto a surface where it’s collected.

To make the test fair, I wanted to start with the same weed for each test. I took 2oz of flowers from an Ultimate Auto #1 plant and ground it all up to ensure similar consistency. Next, I mixed up the ground-up weed and split it into 2 containers and weighed them to make sure everything was equal. We got 2 sets of the same Bubble Bags and made both types of hash using 1 ounce of weed for each test. We processed the Bubble Hash by chopping it up and drying it overnight and put the Dry-Ice Hash in containers since it doesn’t need further processing. It was some of the larfiest buds from the harvest, but covered in trichomes. And this is the same bud after being ground up before we split it into 2 groups. Note: When making hash, there’s no benefit to grinding your bud/trim this fine.

This isn’t a super scientific test, but it should give you a good idea of what to expect if you’re thinking of making either of these two hashes. Although there are many other common types of extract (shatter, RSO, etc.), these two are the most common for home growers since they’re the easiest to make and don’t use solvents. It might be a cliche sentence at this point, but it’s still true. When it comes to whether or not you find something attractive, there isn’t a right or wrong answer. That being said, I feel there’s an obvious hierarchy here. Although both hashes are great, Dry-Ice Hash is just plain prettier. A closeup of Dry-Ice Hash from the same starting cannabis matter. Honestly, neither one of these two hashes is particularly hard to make, especially with the right equipment. In fact, if you haven’t already, I’d encourage to try making both types at home. You can get a feel for the difficulty of each, and as a pretty sweet bonus, you end up with two different types of hash to use! Part of the difficulty with Bubble Hash is that it can be messy to make since it involves lots of water. There is also one step when making Bubble Hash that can greatly affect the level difficulty: the mixing! Bubble Hash can go from being pretty intensive (when you mix the ice water and cannabis by hand) to moderate (using a hand drill) to pretty-easy-but-wet when you use a mini-washer (aka Hash-Machine, shown below). With the mixing out of the way, it’s just a bit of scraping, drying and chopping before your hash is ready. A mixing machine make the Bubble Hash process a lot easier, but you still have the mess of dealing with tons of ice and water. Once the ice water and cannabis have been mixed together and agitated for several minutes, the mixture is poured through special bags (called bubble bags), and the hash is collected with a spoon. The main drawback to Dry-Ice Hash is, well…the dry-ice! Dry-Ice can be harder to obtain than regular ice depending on where you live and it definitely costs more. It’s inherently more dangerous since prolonged contact can give you a mean “burn”. Still, even with those issues, Dry-Ice Hash is incredibly easy to make and if you follow a few easy safety guidelines like wearing oven mitts, the dry-ice won’t cause any problems and ends up being easier to make overall. After mixing your cannabis bud or trim with dry-ice in a bucket, you put the mixture in the same type of bubble bags and shake the hash onto a table. Each hash-making process produces multiple “grades” of hash. I weighed each grade separately and added the results together to get the total yield from each method. Here are pictures of the weigh-ins from the bubble hash. Total Amount of Bubble Hash per 1 Ounce: 4.41 grams. Percentage of Weight Returned as Hash:15.6% Dry-Ice Hash Yield from 1 Ounce of Buds.

Here are pictures of the weigh-ins from the dry-ice hash. Percentage of Weight Returned as Hash: 43.5% Winner: Dry-Ice Hash by a landslide! Potency (Perceived Potency) What’s the difference between “measurable” potency and perceived potency? Both terms are talking about the same thing – how strong the cannabis is – but they’re different in how each one is measured. A closeup of the trichomes on a live cannabis plant. All types of hash are made out of these mushroom-shaped resin glands.

“Measurable” potency (or just “potency”) talks about how strong cannabis is in terms of objective measurements. If you went to a dispensary and purchased cannabis, it would tell you the amount of THC/CBD/CBN the product contains to give you an idea of how strong (or “potent”) it is. “Perceived” potency describes how strong something feels to the person using it .
