how to decarb thca diamonds

Decarboxylating THCA (tetrahydrocannabinolic acid) diamonds is a process of applying heat to convert THCA into THC (tetrahydrocannabinol), which is the psychoactive compound found in cannabis. Decarbing THCA diamonds allows for their use in edibles, tinctures, or other cannabis products. Here’s how to decarb THCA diamonds:

Materials Needed:

  • THCA diamonds
  • Baking sheet or oven-safe dish
  • Parchment paper
  • Oven
  • Oven thermometer (for accuracy)
  • Oven mitts
  • Timer


  1. Preheat the Oven:
    • Preheat your oven to 240°F (115°C). It’s important to use an accurate oven thermometer to ensure the correct temperature.
  2. Prepare the Diamonds:
    • Place your THCA diamonds on a sheet of parchment paper. You can break them into smaller pieces if they are large.
  3. Baking Sheet or Dish:
    • Place the parchment paper with the THCA diamonds onto a baking sheet or into an oven-safe dish. The dish should be shallow to allow for even heat distribution.
  4. Decarboxylation Process:
    • Place the baking sheet or dish with the diamonds into the preheated oven.
    • Set a timer for 30-40 minutes. This is the general range for decarbing THCA diamonds, but the exact time can vary depending on factors like the size and moisture content of the diamonds.
    • During this time, the THCA will undergo decarboxylation and convert into THC. You may notice bubbling or sizzling, which is normal and indicates the release of carbon dioxide (CO2).
  5. Monitor the Process:
    • Keep a close eye on the diamonds to prevent them from overheating or burning. Stir or shake them gently every 10-15 minutes to ensure even decarboxylation.
  6. Check for Decarboxylation:
    • After the allotted time, remove the diamonds from the oven. They should have turned from clear or translucent to a more opaque, golden color. This change indicates that the THCA has been successfully decarboxylated into THC.
  7. Cool Down:
    • Allow the decarbed diamonds to cool down to room temperature before handling. They will become more solid as they cool.
  8. Storage:
    • Once cooled, store the decarbed diamonds in an airtight container in a cool, dark place.

Your decarbed THCA diamonds are now ready for use in various cannabis products, such as edibles, tinctures, or capsules. Keep in mind that decarboxylation can affect the potency of your product, so it’s essential to calculate the desired dosage and proceed with caution, especially if you’re new to cannabis-infused products.
