The Ultimate Solventless Rosin Pressing Resource
Difference between Pillow Tech, Bottle Tech, and Chottle Tech
In the art of rosin extraction, there are several different methods that extractors can use to accomplish the same goal. For example, all rosin extraction involves pressing cannabis material between heated plates, but there are a variety of ways to pack the starting material into filter bags and position it between the plates. These different approaches are referred to as techniques, or “tech” for short. Pillow Tech, Bottle Tech, and Chottle Tech are different ways that rosin filter bags can be used to hold starting material, and how that material is oriented between rosin plates for extraction.

What's The Problem with Using Dry Ice for Dry Sifting?
Dry ice is the solid form of carbon dioxide, capable of achieving temperatures much lower than that of regular ice. Unlike water ice that changes from a solid to a liquid when it melts, dry ice sublimates as it warms up, meaning it changes from a solid directly into a gas vapor. This vapor cools the surrounding environment, which makes dry ice an effective cooling agent. At more than 100 degrees below zero, dry ice gets so cold that it can actually damage unprotected skin.
One of the mantras often heard when working with solventless cannabis extracts like bubble hash and dry sift is “keep tools and environment cold”.

Why It's Important to Pre-Heat Your Rosin Bags for Pressing Rosin
Preheating cannabis starting material is an important prerequisite for extracting rosin. Whether you’re pressing flower, dry sift, or bubble hash, warming the material between heated rosin plates helps prepare the cannabis for extraction. Although pressing material without preheating will still give you results, you can achieve a more efficient extraction and better yields with a quick preheat before full pressure is applied.

Buying vs Building Your Own Rosin Press
A common question for people just getting into rosin is what type of rosin press they should buy. A hair straightener is some extractors’ first foray into solventless extraction, but the limited capabilities of this makeshift approach soon grows old (especially given the easy availability of better alternatives). Although a hair straightener can definitely produce quality rosin, a press that utilizes heated plates designed specifically for rosin production that can generate several tons of pressure is both easier to operate and more efficient for processing cannabis material.

Top 5 Bubble Hash Drying Tips
Ice water extraction is the ideal method used to create high quality bubble hash. While other methods like dry sifting can produce excellent solventless concentrates, ice water offers extractors greater control over isolating trichomes and removing plant contaminants. But after extraction is complete a lot of water still remains, leaving a totally saturated patty of cannabis trichomes. Not only is the hash unusable in this state, but it’s vulnerable to microbial growth like mold.
Just like fruits and other foods, bubble hash can invite microbial growth if there’s sufficient moisture present.

How To Press without Rosin Bags
Rosin filter bags offer many advantages to solventless extractors. They keep cannabis material tight and compacted for a consistent flow of rosin, facilitate even pressure from the heated plates onto the material throughout extraction, and help remove unwanted lipids and plant particles from rosin. Rosin filter bags are a staple of the solventless extraction toolkit. But can you press rosin without filter bags?
The answer depends on what type of cannabis material you’re pressing.

The Anatomy of a Cannabis Trichome and Why It's Important
Know why good cannabis looks like it’s covered in a sugar-like coating of tiny crystals? That lovely layer of sparkling goodness is actually thousands of little appendages that hold the magic of the cannabis plant. These resin-producing glands are called trichomes, and they contain the cannabinoids, terpenes, and flavonoids in highly concentrated amounts. Growers think about cultivating cannabis in terms of flower production, but another way to think about it is through the lens of farming terpenes. At the end of the day, it’s the trichomes we’re after.

Indoor vs Outdoor Cannabis Cultivation
The definitions of indoor and outdoor cannabis cultivation are self-explanatory: indoor growing takes place within an enclosed structure utilizing artificial light, whereas outdoor growing takes place outside using the sun as the primary source of light. Cannabis can be successfully grown in either type of environment. Both indoor and outdoor flowers are capable of reaching incredibly high qualities of flavor and potency. However, there are factors unique to each approach, and pros and cons that come with either type of garden you choose to establish.

Do I Need To Freeze Fresh or Cured Material Before Washing?
We know that cold temperatures are a necessity for producing high quality bubble hash with the ice water extraction method. Cold temperatures make trichomes on the cannabis material brittle enough to fall away from their stalks, while also minimizing terpene loss and helping to keep resin contained within the trichomes. But do we have to actually freeze cannabis material before beginning the process of washing hash?
First, let’s look at the different preparations possible for cannabis material used for washing bubble hash.

Aging Bubble Hash Temple Balls 101
There’s much more to aging bubble hash than simply the passage of time. Without proper preparations and a controlled environment, hash is just getting older in long term storage, not really aging like a fine wine, tobacco, or cheese. There isn’t yet much scientific research that gives us a clear understanding of the chemistry behind the magic of aging bubble hash, but we still have data. That data comes from human experience, passed down through the traditions developed over thousands of years in hash producing regions of the world.

How To Pre Soak Fresh or Cured Material Before Washing for Ice Water Extraction
For thousands of years hash producers have been extracting resin-filled trichomes from cannabis flowers, creating a pure and potent concentrate that captures the most desirable qualities of the plant. The first hash was collected directly by hand from mature flowers, creating a smear of resin by rubbing open palms across the plants. The hash was then peeled away and rolled into balls, called charas.

Wet Trimming vs Dry Trimming Cannabis Flowers
Trimming cannabis involves snipping away excess leaves that grow out of the buds, exposing the swollen calyxes and dense flower structure underneath. Trimming always happens after harvest, but it can take place before or after the flowers have been dried. Wet trimming takes place right after the flowers are harvested, before they’re hung to dry. Dry trimming takes place after the plants have already been hung to dry, before they go into jars for curing.

Bubble Hash Washing Vessel 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.

Rosin Press Hand Pump Modifications
There are several types of rosin presses capable of producing high quality rosin, spanning the range between hair straighteners and fully automated pneumatic presses. Hair straighteners are the most manual of all presses, which require all the pressure to come directly from the weight of the extractor pressing down on the plates. Pneumatic presses are the most automated, using compressed air to generate internal pressure which is controlled by the simple push of a button

How To Use a Pre-Press Mold
Pre-press molds allow extractors to quickly and conveniently compress cannabis material in preparation for rosin extraction. Compacting starting material eliminates gaps and inconsistencies throughout the flower, sift, or bubble hash within a rosin filter bag, allowing for an even flow of rosin as pressure is applied during extraction. If the cannabis material contains pockets of empty space, these mini chasms will collect and hold the freshly-squeezed rosin and prevent it from flowing through the filter bag and onto the parchment paper for collection.
