Once your stir time is completed, lift the top bag with the plant material and strain the liquid into the bucket until only ice and flower are left in the first bag. As you repeat the strain through successive bags, observe the traits of what’s left on the screen. Depending on your needs, various micron filters offer different melt levels. Bubble bags between 73 and 90 microns are assumed to produce the finest resin. To collect the remaining concentrate, turn each bag inside out after draining.
Cooking grade hash is highly contaminated with plant matter. Commonly used to make edibles — hence the name — cooking grade hash is also suitable for sprinkling over bowls or in joints. It consists of both low and high microns, and it doesn’t melt well, so it shouldn’t be used for dabbing.
Trichomes range from 20-125 microns. Filter screens or bags designed to make bubble hash are made to correspond with the bags of varying micron sizes that are used to make bubble hash. If a concentrate has the micron listed on the package, this number indicates the micron size of the bag used for that particular fraction of water hash.
It’s also important to remember that trichomes don’t always conform to micron screen sizes. In fact, trichome sizes are cultivar-dependent. Some cultivars will produce thicker trichome heads, while others will have small heads. Plant maturity will also affect the size. However, the right combination of filter screens and micron sizes can reliably produce quality hash. Most water hash equipment consists of several filtration bags of varying micron sizes.
The final step is to press all excess moisture out of your hash. Drying is arguably the most important factor in ensuring the quality of your final product. Gently press the excess moisture out of your ice hash and then use a butter knife, or razor blade, to break it down into small pieces. If you do not have access to a freeze dryer, the smaller pieces will make it easier for the hash to dry out.
Ice hash is a fairly versatile concentrate. There are several different ways to use ice hash, though some are generally preferred over others. Different methods of use may also suit different needs. Some users may prefer a sprinkle of ice hash over their bowl for an extra potency boost, while others may prefer to dab with ice hash for the full effect.
The 1-6 star rating system is subjective, but it does provide a sufficient avenue to single out quality hash. The higher the rating, the better the bubble hash will melt. The lower the rating, the more plant contaminants the hash will have.
Skunkman’s water-extraction methods paved the way for the first automated sieving machines In the 1990s, as well as new techniques for ice-water extraction. Around this time, Canadian cannabis entrepreneur and activist Marcus “Bubbleman” Richardson entered the scene, eventually revolutionizing the hash world with the Bubble Bag extraction system.
When making ice hash, the goal is always to isolate the trichome glands from the cannabis plant. Any plant material that is not removed reduces the ability to bubble and therefore reduces the quality of hash.
A cannabis concentrate formed by sifting the trichomes of the cannabis plant in the presence of ice water. Ice hash, (commonly referred to as ice water hash, bubble hash, or wet sift) is typically dabbed, but can also be used to add potency to flower.
Different types of bubble hash
Full melt clear dome
- 6 Bubble Bags (220-190-160-120-73-45)
- Two food-grade plastic buckets
- Ice cubes
- A stainless steel skimming spoon
- Oil pads, Slick Sheet or parchment paper
- Small washing machine, which makes the stirring process automatically, saving labor and time. You can also use a plastic bucket to stir the mix in case you don’t have a machine.
When the water is between 0-4ºC – and the plant material is hydrated – gently stir the mix with our skimming spoon/machine for about 5-7 minutes. We don’t want to beat the mix since this would result in a more contaminated resin, we can do it on the second run. Now, let it rest for 4-5 minutes before passing the mix through the screens.
Water hash of excellent quality
If we use dry plant material, we should soak it for a while to re hydrate it; in this way, we’ll find much less plant debris in our hash.
Use a frozen spoon or a plastic card to remove the resin from the bag. The best way to dry our resin is placing it in a dark, cool and dry place. Heating it is not advised since we can harm its organoleptic and psychoactive features. Place it in a non-stick surface and chop it as fine as possible. Some people use a frozen microplane or a strainer for this purpose. Others put the chopped resin in the refrigerator to dry it.
Ideally, our plant material should be frozen very fast (flash freezing), but this is something complicated for amateurs. Then, our options are freezing it in our conventional freezer or just keeping it in the refrigerator, without reaching the freezing point. We prefer chilling our plant material (especially when it is fresh) since in this way the water inside the buds don’t freeze and pierce the plant tissues, enabling chlorophyll to escape and harm our resin. This is an important point especially with live resins. You can check our post on fresh chilled material to make hash to know more about this phenomenon.
Once we have this concepts clear, we can see now how to make the purest possible bubble hash. It should be noted that, when we speak about purity, we are referring to the highest possible concentration of trichome heads, reducing the presence of contaminants like dust or plant debris to the minimum. In short, anything but glandular trichome heads is considered a contaminant.
In this post we tell you the basics for making top grade ice water hash easily at home. Cannabis concentrates are becoming more and more popular, and
