Decarboxylation temperature differs from one cannabinoid to the next. THC, for example, decarboxylates at a lower temperature than CBD. 230 degrees Fahrenheit is a good temperature to gently decarb cannabinoids without destroying them or the terpenes that give marijuana strains their signature taste and scent.
