In the context of weed, carts are pre-filled vape cartridges that attach to a vape battery. Live resin carts are simply vape oil cartridges that have been filled with live resin instead of a more conventional cannabis concentrate. As with any cartridge, simply screw the cartridge onto a battery, activate the heating mechanism, and inhale through the mouthpiece.
How is live resin made?
The live resin process typically uses liquefied petroleum gas such as butane or propane as a solvent, leading many to consider live resin a form of butane hash oil (BHO). Ethanol or carbon dioxide (CO2) are also used for making extracts, but to a lesser extent.
The cannabis plant material is harvested and flash-frozen immediately. Plant material is flash-frozen by either slowly dipping it into an insulated cylinder filled with liquid nitrogen, or placing it in a cooler with dry ice (frozen carbon dioxide) on the bottom. Extractors pack the cannabis into a tank inside a closed-loop system that is dedicated to holding it throughout the process. The tank must be purged of any oxygen prior to passing the butane or other solvent through to ensure that there is no explosion and unnecessary pressure.
The solvent is chilled, then passed through the starting material, releasing the trichomes from the plant matter. To remove the solvent, heat is applied to the combined mixture of cannabis and solvent, causing the solvent to turn into a vapor and rise into the solvent column. There, it is cooled and condensed back into a liquid.
Extractors must always pay careful attention to temperature. Too much heat can ruin an extraction. Heat evaporates the volatile terpenes and triggers decarboxylation, which rids the concentrate of its translucent appearance and turns it into a darker oil.
Again, for health and safety reasons, extract production should be left to professionals since the safety precautions and equipment require precision and accuracy.
