Thanks for my incessant drivel this time goes to @Dred_pirate for tagging me in a thread started by @Merakian_Hash! Here: Propane vs n-Butane Propane vs. n-Butane vs. Alcohol vs. [Insert Solvent] WHY you should read this! Propane and n-butane are very similar, but they definitely extract cannabis differently. Ethanol and other alcohols work, but they also extract more or less undesirables, depending on the alcohol. They key differences between these molecules lie in the differences betwee…
