Everyone makes ice water hash differently, and you can certainly deviate with your own methods at points in production. Our process resembles what top names in bubble hash use as a general standard. If you decide to choose this route, it is vital that you use only the finest flower. As we mentioned previously, you have no chance of producing full melt with an ill-fitting strain. Remember that even some of the top strains don’t do the job for generating bubble hash.
Known to many as “half melt”, 3 and 4 star hash or kief does just that, it half melts. The reason for the half melt is due to the presence of some debris and plant material in the final product, however it is considerably less than 1 or 2 star. These can include tiny bits of leaf material and anything that isn’t a full trichome head or stalk. Half melt adds potency to smoked flower products as a bowl topper but is more often than not pressed into rosin. Half melt does works for dabbing as well, but it should usually be pressed into rosin for the best results.
Bubble hash represents some of the best in solventless cannabis today. That is why rosin pressers love using it for their extractions. However, not all strains are created equal. Not every strain can cut the mustard because how it was grown, the strength of the genetics, the intrinsic terpene profile, and more all play significant roles. Even when strains are capable of producing full melt, the chances of making elite bubble hash can leave even some of the top names in the game scratching their heads. That said, they and aspiring solventless extractors in companies and home operations alike push forward to reach the upper echelon in the category.
–190 micron bag (often debris being filtered out)
In addition to bubble hash, a similar rating system for dry sift and kief has been informally created. The criteria for ranking the materials is close to bubble hash’s guidelines and can have you producing near full melt concentrates as well. However, it should be noted that creating full melt dry sift is not as easy as throwing trim in a sifter. Many mistakenly use dry ice, which rips open the trichome heads and stalks of the flower. This instantly reduces the quality of the final product dramatically. Very delicate sifting, without dry ice or only with very small rice-grain sized dry ice pellets, is necessary to produce light colored rosin.
We reached out to the godfather of the process himself to get some clarification – Marcus “ Bubbleman ” Richardson enlightened us with the following:
- How transparent are the resin glands after they have been at room temperature for at least a few hours?
- Using a high definition microscope, what is the ratio of intact, full trichome heads versus stalks?
- How clean is the hash overall? It should not contain debris such as dirt specs, microfibers, or plant matter.
- Using a quartz nail if possible, do a melt test and see how much char is left on the nail.
–160 micron bag (low quality trichomes)
Reaching a true 6-star caliber can be difficult, but with the right material and processes it becomes much more reliable. 5 star tends to be much easier to produce if you consistently have very high quality material but are still perfecting your wash and dry processes. Creating an elite full melt hash goes beyond the need for quality flower and know-how.
There aren't too many sights and aromas in cannabis that compare to the tiny bubbles that form when dabbing full melt bubble hash. We may not always take notice because we're smoking the delicious concentrates, but those tiny bubbles (and specifically how nothing should be left when they're gone) let you know that you'
Also called Glandular Trichomes. This type is the most common in buds and leafs of cannabis plants (they are only formed during the flowering stage of plants). The average size of their heads is slightly larger than sessile’s, and are the main producers of cannabinoids and terpenes. They are called like this precisely for the height of their stalk (150-500 microns). It is the only type of trichomes that has a layer of cells between the gland and the stalk; these cells can be broken, detaching the head from the stalk. This is why these trichomes are the most suitable ones to make top grade hashish.
Cured resin is pressed more easily than non-cured glands, and is also more potent and flavourful. The ideal curing temperature is 37ºC, and we should open our jars every 2-3 days to renew the air inside them.
So, if we want the best possible quality, filtering “downwards” with a 160 micron mesh is not enough. We should also perform a second sieve to get rid of those particles smaller than certain size. In most cases, we can get excellent results by using a set of three screens: 160, 70 and 45 microns. The first thing to do is getting our raw resin with our 160 micron mesh. Put the raw resin on a 160 micron mesh and gently card it to separate the heads from the stalks. Once done, put the filtered resin on a 70 micron mesh to separate the smaller particles. We have now 2 qualities: the former is composed of particles from 70 to 160 microns (first quality), the latter from particles smaller than 70 microns (second quality). We can clean this second quality by putting it on a 45 micron mesh and carding it, thus separating the smaller particles – which will pass through the mesh – from the larger ones. All particles that passed through the 45 micron mesh are our third quality.
We are talking about quality as purity. We understand purity as the higher possible concentration of heads of capitate-stalked trichomes (glandular trichomes) with the minimum possible presence of smaller heads, stalks, plant debris, etc. In most cases, the purest sample will also be the best product, both organoleptically and regarding the chemotype. It may also be worth, in order to widen the terpene range, to mix several screens; in this way, perhaps the final product doesn’t look so nice, but the organoleptic properties may be greatly improved in some cases. Recent studies have also shown that terpenes do have an influence on the effects of cannabinoids.
Once we have all the theory clear, let’s see how to make the purest possible dry sift separation. We will use an ancient technique in which we sieve and re-sieve the resin glands with screens of different sizes. We can use either sieving screens or bags (if we use bags we need to have the screen very tense).
The first thing we should know before trying to make the best possible dry sieved trichome separation is what types of trichomes we can find. As the plant ripens, trichomes segregate higher amounts of cannabinoids and terpenes. The three types of trichomes found have several features in common; they have a gland where cannabinoids and terpenes are segregated, a group of cells that attach the gland to the stalk, and the stalk itself, which joins the gland to the plant tissue. Let’s make a brief description of each of them.
We also want a hash free from external contaminants such as dust, soil, small insects, plant debris, etc. The cleaner our growroom and plants are, the cleaner our resin will be.
In this post we present you a system to obtain top grade dry sift separations easily and without investing in expensive equipment. All we need to obta
