The Ultimate Solventless Rosin Pressing Resource
New Product Drop: The Press Club Hash Wrappers
Press bags have come a long way. They've evolved from basic mesh pouches into precision-engineered tools that are now standard in solventless extraction. And The Press Club has been there for the entire ride. But even with all that progress, anyone who's pressed enough rosin knows the frustration of seam failures, misting, bleeding, and full-on blowouts. Cheaply made bags with poorly constructed seams can ruin a batch and waste premium material in seconds.

How To Decarb Rosin and Make Powder for Edibles and Beyond
Rosin is one of the most incredible cannabis extracts you can make. No solvents, no mystery chemicals, just heat and pressure coaxing resin out of trichomes. But if you want to use that rosin in edibles, tinctures, or capsules, you need to activate it first through decarboxylation. And if you want to take things a step further, you can turn that decarbed rosin into a shelf-stable, easy-to-dose powder that works in drinks, food, or by itself.

The Best Ice Shape for Washing Hash and Why It Matters
Most hash makers obsess over their bags, their wash technique, and their starting material. All of that matters. But there's one variable that doesn't get enough attention, which is the ice itself. Not all ice is created equal when it comes to washing hash. The shape, density, and melt rate of your ice can make or break your wash.
Let's break down why ice shape matters and which types will give you the cleanest trichomes.

How To Clean Bubble Bags with Alcojet (Instead of ISO)
You've spent tons of time hunched over a sink scrubbing resin out of bubble bags with isopropyl alcohol, and you know the pain. Your hands smell like a hospital, your back hurts, and there's still sticky residue clinging to the mesh like it's personal. There's a better way, and it doesn't involve any scrubbing at all. The answer is Alcojet and a small washing machine. This combo will clean your hash washing bags faster, easier, and safer than the traditional iso soak ever could. Let's walk through how it works

Using Vibrating Screens for Washing Hash
Vibrating screen systems use stainless steel hardware instead of traditional nylon bags. This method can be used either as a second wash to further clean already collected heads or as a first pass alternative to bag-based methods. Is this just a refinement tool for perfectionists, or could it be the next step in the evolution of solventless extraction?
Let's break down how these systems work and what they bring to the table. A vibrating screen hash wash system consists of a stainless steel vessel with a stack of precision-micron stainless screens and a vibrating motor attached to the side.

The History of Cold Water Hash
The roots of cold water extraction reach back to the early-to-mid 1980s, when underground growers began experimenting with ice water as a tool for separating resin from trim. The fundamental principle was elegantly simple: submerge cannabis material in cold water, provide agitation, and observe as dense trichome heads sink while lighter plant matter floats. This physical separation required no solvents, no chemistry degree, just ice, water, and patience.

Using Feminized Cannabis Seeds for Washing Hash
Feminized cannabis seeds have transformed cultivation, unlocking unprecedented efficiency and crop predictability for growers. But as the solventless extraction movement continues to gain momentum, hash makers are asking an important question. Do feminized seeds hold up when it comes to ice water hash production? For extractors who depend on premium resin quality and consistent wash performance, understanding how feminized genetics perform in solventless applications is critical to making informed cultivation decisions.

Rescheduling Medical Marijuana and What It Means for Solventless Extractors
On December 18, 2025, President Trump signed an executive order directing the rescheduling of marijuana from Schedule I to Schedule III under the Controlled Substances Act while simultaneously expanding access to CBD products. This represents one of the most significant cannabis policy shifts in modern U.S. history, with implications that extend far beyond headlines. For every segment of the industry, from cultivators to concentrate makers, this moment marks a turning point in legitimacy, research opportunity, and market potential.

What Is True 6-Star Full Melt & How To Test It
Six-star hash, or full melt, is the highest grade of solventless concentrate that hash makers can achieve. As the absolute unicorn of solventless concentrates, you can always trust that the best of the best is defined by purity, meltability, and minimal residue. But the thing is that as more people enter the solventless space, the term "full melt" gets thrown around pretty loosely. Standards matter more than ever, and testing is how we uphold them.

Optimizing Quartz Surface Temperatures for Dabbing
If you've ever taken a dab that was way too hot, you know the feeling. That harsh, chest-tightening cough paired with a burnt flavor that masks everything good about your concentrate. Temperature control is everything when it comes to dabbing, especially if you want to experience the full spectrum of flavors and effects your rosin has to offer. Quartz bangers have become the gold standard for flavor chasers and concentrate connoisseurs, but owning a quality banger is only half the equation. The real skill comes from understanding how to use it at the right temperature.

Is Your Cannabis Crop Better for Flower Rosin or for Ice Water Hash Production?
When you’re growing cannabis for solventless extraction, you can take two different paths if rosin is your end goal. You can press flower rosin, or you can wash the flower for ice water hash. Both produce clean, solvent-free concentrates that showcase the plant's natural compounds, but they require different starting material and yield very different results. If you're a cultivator deciding how to process your crop, the central question is simple but critical

The Importance of Tolerance Breaks and the Endocannabinoid System
If you've been using cannabis regularly for a while, you might have noticed that the effects don't hit quite like they used to. Maybe you need more flower to feel the same effects, or your regular sized dabs aren’t doing the trick anymore. That's tolerance at work, and it's a completely normal part of the game. The good news is that taking a break can actually help you get more out of your cannabis experience in the long run.

Irrigation for Multiple Cultivars in a Grow Room
Growing multiple cultivars in a single room is common practice for commercial cannabis operations, and also tons of hobby growers too. It allows cultivators to offer variety, test new genetics, and meet market demands under one roof. But the challenge is that not all cultivars are created equal. Growing cannabis is not a one size fits all ordeal. Each strain has its own genetic expression, growth patterns, and nutritional requirements.

How To Wrap & Press Hash Without Rosin Bags
Rosin pressing traditionally relies on pre-made bags with stitched seams to contain hash during extraction. While convenient, these seams create problems that compromise both yield and purity. Stitching creates larger holes at attachment points, often exceeding 25 microns even when the mesh itself is finer. Resin gets trapped in seam crevices or leaks through stitch holes, and the structural integrity around stitched areas remains inconsistent.

Why Does My Rosin Bubble When It's Heated?
That bubbling effect has a nickname among hashmakers: "champagning." It refers to the gentle boiling and bubbling you might notice when rosin is heated on a nail or inside a jar at room temperature over time. While it might look like some kind of reaction or impurity, this bubbling is actually a combination of natural processes tied to the composition of the rosin itself.
