What Is the Difference Between Microplaning and Sieving for Air Drying Bubble Hash?

Drying your freshly made bubble hash is the final step of the ice water extraction method of solventless extraction, and it’s a make or break process. Get it right and you’ll have an evenly-dried batch of bubble that’s ready for rosin production or enjoyment just as it is. Get it wrong and you can invite microbial growth and end up with a mildew-riddled product that’s only good for the trash bin. Drying is critical, but it can also be a bit tricky if you’re not familiar with the methods.

Top 5 Common Mistakes When Washing Hash and Dry Sifting

One of the things we love most about our work in the solventless community is sharing the tips and tricks we’ve picked up over the years in working with the cannabis plant. Solventless extraction requires knowledge of cannabis, its trichomes, and the techniques and best practices required to isolate, collect, and process them. The resulting concentrates, when made with care and intention, capture the essence of the cannabis plant better than anything else available.

Bubble Wash Bucket Insulation Guide

If you want to wash bubble hash there’s one thing you need without question, and that’s ice cold water. In addition to a set of quality bubble wash bags, frigid water is central to the process of creating solventless hash. Mixing cannabis flowers or trim leaves and ice water together in a wash bucket allows trichome heads to fall away from their stalks and separate from the unwanted plant material. The cold temperature of the water makes the trichome stalks brittle enough to break, and also minimizes the likelihood that the heads will rupture and leak their valuable resin.

How To Prepare Fresh Frozen Cannabis and Average Yield for Washing Bubble Hash

Fresh frozen cannabis is a type of starting material used in the ice water extraction method of creating bubble hash. The difference between fresh frozen and other types of cannabis material, such as dried and cured flowers, is in the specific treatment of the material after harvest. Fresh frozen cannabis is grown in the same way as cannabis destined to be air cured in the traditional fashion, but rather than hung to dry, fresh frozen cannabis is harvested and then immediately frozen at subzero temperatures.

Top 5 Ways to Keep Your Water Cold for Ice Water Extraction

Cold water is essential to the ice water extraction method of making bubble hash. Cold temperatures allow for the trichome heads to break free from their stalks and the rest of the plant material, while remaining intact at the same time. Warmer water creates an environment where the trichome heads can more easily rupture, stick together, and become difficult or impossible to collect. Without cold water, you’re left with drastically less trichomes to sieve out of the water and what you attempt to collect will be a greasy mess.

Top 5 Reasons to Use All Mesh Bubble Wash Bags

All bubble wash bags utilize the same basic technology, but not all wash bags are created equal. Although every wash bag incorporates mesh sieving screens into a bag-shaped design, the actual construction and materials of wash bags can differ. Traditionally, bubble wash bags were made with waterproof nylon side walls attached to a mesh screen at the base of the bag. Water can only pass through the mesh screens at the bottom of these bags, essentially limiting the surface area through which the ice water extraction actually takes place.

What Is the Purpose of Using Multiple Bubble Wash Bags for Ice Water Extraction?

Wash bags are the central piece of gear used in the ice water extraction process, a solventless method of making bubble hash. Wash bags are nylon bags that fit inside of a bucket and stack one inside of the other, secured along the top rim of the bucket. Wash bags are made in various sizes to accommodate different amounts of cannabis material.

What Is Bubble Hash?

Bubble hash is a type of cannabis concentrate, a collection of the plant’s most potent attributes, made using a simple and chemical-free extraction process. Bubble hash, or simply “bubble” is a pure and potent form of cannabis medicine, perfect to consume by itself or to use as a starting material for other forms of cannabis concentrates. Bubble is not only incredibly powerful and effective, but it’s clean as well. Bubble hash is referred to as a solventless cannabis product, since no solvents are used to create it.

How To Use a Work Bag for Washing Bubble Hash

Work bags are enclosed mesh filter bags used to hold cannabis starting material during the mixing phase of ice water extraction. Zipper work bags are similar to regular open-ended work bags in that they utilize the 220-micron filter screen size, however they’re designed to fully contain the cannabis material with a top lid that zips closed. Zipper wash bags are also made entirely with 220-micron mesh so that the total surface area acts as a filter.

How Does a Freeze Dryer Work?

Freeze dryers have grown in popularity in recent years, as solventless extraction artists are constantly improving on the quest to produce the world’s best bubble hash. For commercial and craft producers alike, freeze dryers present the most optimum solution to quickly and thoroughly dry fresh ice water hash. For decades, other methods have been successfully used to dry wet bubble hash, but in terms of overall quality and terpene preservation freeze dryers offer a better solution than the other approaches.

How Long to Mix Cannabis and Ice Water for Washing Bubble Hash

Washing hash involves mixing ice water and cannabis material together in order to separate trichome heads and isolate them through a series of mesh filter bags. The same material can be washed multiple times, and for varying lengths of time with each round of washing. The length of washing time impacts the number of trichomes released from the material, as well as the amount of plant contaminant that may end up in your hash.

What Is Ice Nucleation in Fresh Frozen Cannabis?

Like humans, living cannabis plants are composed mostly of water. At around 80% of their total weight, water accounts for the bulk of a cannabis plant’s biomass. After harvest, water slowly evaporates during the drying and curing process. But cannabis doesn’t have to be air dried in preparation for hash production. Fresh frozen cannabis has become the predominant source material for creating bubble hash and hash rosin. Freezing cannabis immediately after harvest allows us to capture and preserve the high terpene content that’s present in the living plant

Why Does Ice Water Change Colors When Washing Hash?

Cannabis material that’s properly washed for bubble hash often imparts a cloudy appearance in the wash due to thousands of trichome heads released into the ice water and cannabis mixture. It’s common to see an off-white color in the hash water, indicative of the resin that’s been effectively separated and left suspended in the water. In addition to the cloudy, creamy look of hash water, a greenish hue is also common. Green water is a sign of plant contamination and an early indicator that the quality of your hash may be compromised.

How To Make a Bucket Stacking System for Washing Bubble Hash

✅ Updated 7/18/21 When it comes to visualizing the process of washing bubble hash, a series of filter bags stacked one inside of the next is likely one of the first images that comes to mind. These filter bags, or bubble hash wash bags, are where all the magic happens. The sequence of nylon filters, arranged from largest to smallest in pore size, allows solventless extractors to isolate and collect mature trichome heads which compose the highest quality of bubble hash. Fitting the bubble hash wash bags together in sequence within a 5-gallon work bucket provides an effective and convenient configuration for hash production.

Best Tips To Reduce Stress on Your Back While Washing Hash

For the passionate hash maker, washing bubble hash is normally a labor of love. But there’s no escaping the hard work required for a solid day of ice water extraction. In contrast to pressing rosin, washing hash can be physically taxing. Lifting and holding water-filled wash bags in suspension while they drain is one of the most difficult aspects of the job. There’s also the matter of hunching over your work bucket, scooping and lifting ice, and pouring water. With potentially dozens of repetitions in a day, and hundreds over the course of a week
