NOTE: Decarboxylation is only for specific, rare herbs and exotic flowers. Do NOT attempt with common culinary herbs or fruits, as it will remove their moisture and flavor.
NOTE: Your oven may not be a precision appliance; this is normal. Most ovens operate on an approximation, average, or range of values for any given temperature. Therefore, calibrating your oven is essential to accurate decarbing and baking. Do NOT skip this vital step, or your sample could be destroyed. After calibration is completed, proceed to Phase 2.
Phase 1: Calibrate your oven
Phase 2: Decarb your herb
While 250°F/121°C is the optimal temperature to activate T-C, slightly higher temperatures (along with longer cook times) are effective at activating other beneficial cannabinoids like C-D and C-N, should you choose to highlight them instead. Please note that while higher temperatures/times help activate C-D and then C-N, each higher temp/time can also diminish the effect of a previously activated cannabinoid.
If you do not have a DecarBox, use an oven roasting bag or on a rimmed baking sheet. Make sure the pan is the correct size so there is not an empty space on the pan. Bake the cannabis for 30 to 40 minutes, stirring every 10 minutes so that it toasts evenly. When the cannabis is darker in color—a light to medium brown—and has dried out, remove the bag or baking sheet and allow the cannabis to cool. It should be quite crumbly when handled.
