Step-by-step guides and SOPs for cannabis and hemp extraction methods including BHO, ethanol, CO2, and solventless techniques.

How to Make Live Resin Vape Carts: From Fresh Frozen to Filled Cartridge

Most live resin vape carts on dispensary shelves are not live resin in any meaningful sense. They are distillate with botanical terpenes and a label. The actual process of turning fresh frozen cannabis into a filled cartridge requires a specific extraction pipeline (see our extract density reference for fill weight calculations), precise decarboxylation, and formulation [...]

How to Make BHO Wax: Butane Extraction SOP for Every Texture

Shatter and wax come from the same butane crude; the vacuum purge decides which one you get. Pour the recovered crude 3 to 5 mm thick on PTFE parchment, rest it 15 to 30 minutes, then hold it at 90F for 2 hours at 29.5 inHg or deeper, ramp to 100F for 2 hours and [...]

CO2 Extraction for Cannabis: Supercritical vs Subcritical Complete Guide

CO2 Does Not Care About Your Marketing Claims Every equipment vendor selling CO2 extraction systems will tell you it produces “clean, solventless” extract. That framing is technically defensible and practically misleading. CO2 is a solvent. It dissolves target compounds under pressure and releases them when you drop that pressure. The fact that it evaporates completely [...]

Cannabis Extraction Lab Safety Equipment: The Complete Compliance Checklist

A cannabis extraction lab passes its safety inspection on six systems, and inspectors check them in a predictable order: a room classification stamped by a licensed engineer (NFPA 70 Article 500; Class I Division 1 for any room where hydrocarbon solvent is open to the air), fixed gas detection alarmed at or below 25 percent [...]

How to Press Rosin from Flower: Complete SOP for Maximum Yield

What Is Flower Rosin? Flower rosin is a solventless cannabis concentrate made by applying heat and pressure to dried cannabis flower. No butane, no ethanol, no CO2. Just mechanical force and controlled temperature squeezing cannabinoids and terpenes out of the trichome heads and onto parchment paper. The result is a golden, terpene-rich extract that preserves [...]

How to Make RSO (Rick Simpson Oil): Complete Extraction Guide

RSO oil, also known as Rick Simpson Oil, is a full-spectrum cannabis extract made by dissolving dried flower in 190-proof ethanol at a 750 mL per ounce ratio (roughly 3 cups per ounce of flower). The traditional Rick Simpson method used 1 gallon per ounce, but that volume of ethanol creates unnecessary fire risk during [...]

Cannabis Winterization: The Complete Guide to Dewaxing Extracts for Maximum Purity

Cannabis winterization is the cold-ethanol step that strips fats, waxes, and phospholipids out of crude extract before distillation. The process in four numbers: dissolve the crude in 190-proof ethanol at 10 parts ethanol to 1 part crude by mass, chill to -20°C for ethanol crude or -40°C for hydrocarbon crude, hold 12 to 24 hours, [...]

How to Make THCA Flower from Hemp: Chemistry, Compliance, and the Regulatory Clock

The conversation around THCA flower has been dominated by compliance anxiety for so long that the actual science barely gets airtime anymore. I find that frustrating. Not because compliance is unimportant, it is critically important right now, but because operators who do not understand the chemistry underneath the product are going to get crushed when [...]

Full Spectrum vs Distillate: The Chemistry Behind Cannabis Extract Types

What Is the Difference Between Full Spectrum and Distillate? What is the difference between full spectrum and distillate cannabis extracts? Full spectrum extract is a minimally refined cannabis oil that retains the plant’s complete chemical profile, including cannabinoids, terpenes, flavonoids, and other native compounds. Distillate is a highly purified extract produced through vacuum distillation, typically [...]
