You don’t have to grind the THCa flower before decarbing. nThe best approach is to break the flower into small and even pieces. If you leave larger, uneven chunks, the heat won’t decarb the material evenly. nWhen you grind hemp flower before decarboxylating, the heat affects the flower material evenly. This is the main perk about grinding the flower before decarboxylation. nHowever, ground flower may require a different decarbing time because it may burn more quickly. If you’re not being careful, you may burn the cannabinoids in the process. nIf you have a pre-ground flower on your hands, you should still bake at 240°, but shorten the time for baking if necessary. Watch it closely! n
