The cannabinoid decarboxylation step is performed differently in nearly every lab. To create certain products, THCa, CBDa, CBGa, and many other cannabinoids must all get decarbed. Why and how does Decarb happen? One example is that CO2 extractors often decarb the biomass to improve their efficiency and yield. A second is when some manufacturers prefer […]
