Separating them from the buds is a centuries-old practice, but, today, there are various ways to do so. One example is using dry ice to produce what is now known as bubble hash. A solvent-less concentrate, it is the purest form of hashish.
How To Make Bubble Hash
There are different methods to make hashish. Some use butane or water while others utilize heat and pressure. And then, there’s the dry ice or ice water, which produces bubble hash.
Refined by Marcus “Bubbleman” Richardson, the process has multiple levels of screening to remove plant materials and impurities. The dry ice procedure ensures that the by-product is pure as the buds do not get wet. Moreover, it is also a faster and easier technique to perform.
Dry ice hash also has some advantages over the others. Concentrates made with solvents can still contain amounts of the solvent used. By making the hash correctly, this, of course, is avoidable. Using dry ice, on the other hand, leaves nothing but the resin as no solvent is ever applied, and the dry ice just turns into gas.
Ingredients and Materials:
- 1-2 oz of cannabis trims/buds. For top-quality bubble hash, using high-quality buds is a must.
- 2-3 lbs of dry ice. Dry ice degrades fast, so it should be used immediately after obtaining it. For that reason, getting hold of the other ingredients and materials first is a great idea.
- 2 bubble bags. These are also called micron bags with sizes measured in microns. The lower the number, the smaller the holes are. A 73-micron bag will produce a golden-colored resin with no plant material. For this recipe, use both 73 mc and 120 – 160 mc bags.
- A 5-gallon bucket. A dry, clean bucket at about the size of the bubble bag would work best.
- A pair of gloves. Dry ice has an average temperature of -109.3 degrees F or -78.5 degrees C, which can harm the skin through direct contact. Thick, waterproof gloves should be used, such as snow or BBQ gloves.
- A flat surface. It is where the resin will fall off before being collected, so it should be spotless.
- A scraping tool. A paint scraper (unused) or a credit card will work.
- Optional materials. A heating mat can be used to dry the resin out completely. The end product can then be pressed into a hash using a pollen press.
Dry ice is safe to use, but it still poses risks if not handled correctly. As it sublimates (transitions to gas from solid), it is better to do this recipe in a well-ventilated room. The disposal is simple, although some people might not know better. It should be left on its own to let it turn into gas. Dumping it down the sink could freeze the water pipes. Meanwhile, storing it in an airtight container could pressurize the container.
Once every ingredient and material is ready, it is time to turn the weed into hashish. The steps are pretty straightforward, but as the process involves dry ice, it is essential to follow the safety instructions above and wear gloves at all times.
- Crumble the buds (optional). This step is optional and only if the buds are large and compact. Gently crumbling it down into smaller pieces can ensure that more trichomes come in contact with the dry ice. However, one needs to be careful at this step since too much handling and grinding the flowers might result in a contaminated resin.
- Put dry ice and weed in the bucket and shake. If the dry ice comes in large chunks, it is better to break them off with a hammer first. Then, put both dry ice and weed into the bucket and cover the container with the 73-micron bag. After which, one should gently shake the bucket for 2 to 4 minutes. This way, the trichomes freeze and become brittle, making it easy for them to detach from the plant.
- Transfer the mix. After freezing the trichomes, it should then be transferred to the bubble bag. Simply invert the bucket so the contents would fall into the bag.
- Extract the resin. The bag will have to be shaken gently to let the resin rain on the flat surface. The keyword here is “gently” as shaking too much will shred more plant matters, which might contaminate the concentrate. The extraction time varies, mostly due to the type of weed as some have trichomes that detach easier from the plant. The intensity of the shaking is also a factor. Gently shaking the bag can make the process longer.
- Collect the resin. The extraction time is about 20 – 40 seconds long on average. After which, the resin (or the kief) can then be collected and transferred to a clean container. This process can be repeated, although the succeeding runs might result in a lower-grade hash.
- Transfer to a heating mat (optional). While the result is not wet, as opposed to ice water hash, there might still be some moisture due to condensation. Some choose to dry it using a heating mat at 98.6 degrees F or 37 degrees C. If unavailable, letting it dry for a few hours will do the trick.
- Repeat the process. After collecting the resin, the cannabis and dry ice can be returned to the bucket to start the process all over again. More dry ice can be added to ensure that there’s enough to freeze the remaining trichomes. This time around, though, one must use the bigger sized bubble hash bags. Sometimes, people also pass cannabis through a 220 mc bubble bag, which produces a low-grade yet fragrant resin.
- Make it into a hash. Before storing the resin away, it should then be pressed using a pollen press to form it into a hash cake. People also press it manually into a ball.
Enjoying The Bubble Hash
If the instructions above are followed correctly, the by-product should be a pure high-grade bubble hash. People can break off a small chunk from the cake or ball and dab or vape it, or even roll it into a hash joint. Oral consumption is also possible by infusing it into a beverage.
